What will happen if the gate is reversed?
If it was a gate turn-off dimmer, when a negative pulse (i.e., reverse voltage) was applied to the gate, the base current of V2 would decrease, causing Ik and Ic2 to decrease, and the decrease of Ic2 would cause la and Ic1 to decrease, resulting in the decrease of the base current of V1, thus forming a strong positive feedback. However, for other components, the reference did not mention the situation of adding reverse voltage to the gate, so it was impossible to answer accurately. Read more exciting novels for free
What will happen if the generator is reversed?
Different types of generators had different effects. For a self-excited direct current generator, the induced electromagnetic force produced by cutting the residual magnetic field during reverse rotation was opposite to that during forward rotation. The magnetic field produced by the exciting current was opposite to the remanence, which would make the remanence disappear, causing the generator to be unable to generate electricity. For a separately excited generator, the reversal had no effect on the exciting, but the output voltage and current had the opposite poles. For alternators, the phase sequence will be reversed when they are running in reverse, the ventilation may not be normal, the fastening may be loose, and the oil-glazed bearings may have less oil. If the permanent magnet generator is reversed, it can generate electricity and supply power normally. However, for the generator with an exciting machine, the pointers of the voltage meter and ammeter will be reversed when reversed (there is no such phenomenon for small generators without special exciting machines). In addition, when the generator is reversed (from output power to absorption power), if the power plant is operating in a small grid, the frequency of the entire power grid will drop, affecting the stability of the power grid, and the exhaust cylinder and the last stage blade of the steam turbine will quickly be overheated. Due to the lack of steam or a small amount of steam entering the steam turbine, the last stage blades of the steam turbine generated friction, causing the low pressure cylinder of the steam turbine to be overheated and damage the last stage blades. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What will happen when the generator is reversed?
If the generator was reversed (assuming an abnormal reversal): 1. ** For conventional generators (such as steam turbine-generators)** - ** Electricity ** - The phase order would change. If the generator was connected to the power grid or other electrical equipment, the phase sequence change might cause damage to some equipment sensitive to the phase sequence. For example, the three-phase motor might reverse (if there was no phase sequence protection device), affecting the normal production process. For example, some equipment in the factory that relied on the motor-driven conveyor belt, pump, etc. would run in reverse. - The generator's exciting system may be affected. During normal operation, the magnetic field, current, and other parameters of the generator were designed according to the forward rotation. The reversal may cause the relationship between the magnetic field and the induced potential to be disordered, affecting the voltage regulation and other functions of the generator. There may be voltage fluctuations, instability, and even the inability to establish voltage normally. - ** Mechanical aspects ** - The cooling system might not be working properly. For example, in some cases where the cooling fan was driven by the rotation of the generator to cool the generator, the reverse rotation would cause the cooling fan to be unable to blow in the design direction, resulting in a decrease in the cooling effect of the generator and an increase in temperature, which would accelerate the aging of the insulation materials inside the generator and reduce the service life of the generator. In serious cases, it may cause faults such as internal short circuits in the generator. - For the generator connected to the prime motor, if it was directly connected through a shaft, the reversal might cause damage to the prime motor. For example, if the steam turbine was forced to reverse, the force on the blades, shaft and other components inside would change, which might lead to serious problems such as blade damage and shaft bending. 2. ** For wind power generators ** - ** In terms of structure ** - The force on the leaves would completely change. The blades of the wind turbine were designed to withstand the wind according to the normal direction of rotation. When the blades were reversed, the force on the windward side and the leeward side of the blades would be reversed, which might cause the stress on the blades to exceed the design limit, which could easily cause serious accidents such as blade fracture. - The force on the tower would also change. During normal operation, the tower of the wind turbine was designed according to the direction of the force generated by the rotation of the blades. When the tower was reversed, it might be subjected to abnormal twisting force, which would affect the stability of the tower. In the long run, it might cause the tower to be deformed or even collapse. - ** Power Generation System ** - The control system of the generator adjusted the power, speed, and other parameters according to the normal direction of rotation. When it was reversed, the control system might not work normally, resulting in the inability to generate electricity effectively. It might even cause unstable power output and power quality deterioration (such as frequency fluctuations, voltage fluctuations, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reversed Dream
"Reversed Dream" had a special meaning in the game "Mountain Sea Traveler." In the game, the protagonist,"Dream Defier" Qiyun had special abilities, and "Dream Defier" was one of the core gameplay. Dream Definers could collect thoughts and turn them into perception (each time they extracted the correct thoughts, it would consume energy), and then stimulate the corresponding NPC to change its decision, thus completing the change to reality. For example, Qiyun needed to enter the villagers '"memory level"(the gameplay was similar to the Super Dream in 2077 or the detective mode in Batman), collect "perception"(key clues) to guide the character's behavior and change their fate. This process was called "reverse dream." After the "reverse dream" was successful, it would affect the real environment and promote the development of the plot. The novel "The Curly Witch Never Admits Defeat" is equally exciting. Everyone is welcome to read it!
Reversed drying
Reversed drying was a drying technique. During the drying process, the direction of the hot air could be changed. In this way, the wrinkles, entanglement, and distortion of the dried items could be reduced. For example, the stone mini washing and drying machine M1 Pure was equipped with this kind of forward and reverse two-way drying design to achieve a better drying effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
But the sound is reversed
If the " voice is reversed " here referred to the phenomenon of voice reversal, in a broad sense, it referred to the phenomenon of a singer's voice becoming hoarse and no longer mellow. Now, in the entire field of singers, it generally referred to the decline in singing skills and the wear and tear of vocal cords. There were two understandings of this kind of voice failure in the market. One was that in a broad sense, any decline in singing skills could be called voice failure. The other was that in a narrow sense, voice reversal referred to the irreversible damage of the cricothyroid muscle that controlled the closure of the vocal cords in vocal music, thus affecting the tone, range, and cavity ability. Generally speaking, after a voice reversal, a singer's vocal range and tone would experience a significant decline and change. If there was another meaning to the phrase 'the voice is reversed,' it would be difficult to answer precisely due to the lack of more background information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A reversed portrait
There were many situations related to reversed portraits mentioned in the reference materials: - In the field of investment, Adam's theory included reverse portrait prediction, which was the reversal form of the K-line chart. The principle was that many stocks and futures had strong trends, and the price support and pressure were regular. By copying and reversing the past K-line trend, the future trend could be predicted to a certain extent. The investor should not set the time interval of the K-line selection too short. After using the last trading day as the reversal portrait, he should choose a few more dates as the "last trading day", and then compare the multiple reversal portraits to find the direction with the greatest possibility. However, the analysis of security investment is based on probability, so it is necessary to pay attention to the deviation and correct it at any time. - In the search for the human trafficker, Aunt Mei, there was a situation where Aunt Mei's portrait was reversed. Initially, there was an unofficial second portrait of Aunt Mei that was spread. After the official refuted the rumor, the original portrait was drawn according to the description of the old man who lived with Aunt Mei. The similarity was close to 90%. However, it was not verified by the authorities and was quickly released by the father of the abducted child. Finally, after the suspect identified it, the second portrait was less than 50% similar to Aunt Mei. At present, only the first print released by the government in 2017 was confirmed. - In the stories related to the spy war, there were portraits that triggered the "butterfly effect." The identity of the person in one of the portraits caused the story to reverse. The person in the portrait was Gu Yizhong's butler, Fu Gui. This made people who knew about this matter instantly alert. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The positive and negative connection of the ammeter is reversed. Why is it reversed?
The working principle of the ammeter was based on the effect of the magnetic field on the current. When the current flows into the positive terminal of the ammeter and flows out of the negative terminal, the force received by the coil inside the ammeter in the magnetic field will cause the pointer to deflect in a positive direction. If the positive and negative terminal were connected in the opposite direction, the direction of the current would change from the negative terminal to the positive terminal. Then the direction of the force received by the coil in the magnetic field would be opposite, causing the pointer to deviate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
