Single-phase electric conversion three-phase electric energy using electric welding machine?
The electric welding machine was a device that could convert 220V and 380V alternating current into low-voltage direct current. Its main function was to carry out welding operations. It did not have the function of converting single-phase electricity into three-phase electricity, so the electric welding machine could not be used for single-phase to three-phase electricity.

Single-phase electric meter current 10A
If the single-phase meter current is 10 amps, this 10 amps may be the nominal current. The rated current was used to calculate the base current value of the load. The smaller the rated current, the smaller the starting current of the electric meter, and the more sensitive the electric meter was. For example, if the starting current of the meter is 0.5% of the nominal current, then the meter will start counting as long as the current in the meter circuit is higher than 0.05A, and the meter will not count if it is lower than this value. Single-phase electric meters often have different specifications such as 10, 20, 40, 60, 80, 100A, etc. When using an electric meter with 10A current, you need to consider its matching with the power consumption. The current parameters are neither the bigger the better nor the smaller the better. It should correspond to the power consumption. The maximum current of all electrical appliances should be calculated. If the current parameters of the electric energy meter are small, the electric energy meter may burn. Therefore, it is usually recommended to choose an electric energy meter with a slightly larger current parameters.

Reverse Connection Diagram of Single-phase Electric Machine
The following are several types of single-phase motor reverse connection methods:
1. For a motor with two identical winding and three-terminal connection (1/3 is the common terminal of the two winding, connected to L of the AC power supply, and 2/4 terminal is connected with the starting capacity), if the N terminal of the AC power supply is connected to terminal 2 for forward rotation, then N is connected to terminal 4 for reverse rotation.
2. For the agricultural single-phase motor (the main/secondary winding is different, there are four terminal: 1/2 for the main winding, 3/4 for the secondary winding), the two copper plates can be connected vertically to achieve reversal (the starting capacity, CPR, is connected between V2 and Ce, the running capacity, CPR, is connected between E and Ce, and the live line and neutral line are connected).
3. Another method was to cut the wires to connect to T1 and T2 of the reversing switch, and the other one was short-circuited to L1 and L2. The wires connecting U1 and W1 were also cut to connect to L3 and T3, and then connected to 220V alternating current to achieve reversal.

Single-phase AC electric meter circuit diagram
When the single-phase AC electric meter works, when the electric meter is connected to the circuit to be tested, the voltage of the circuit to be tested is added to the voltage coil. After the current of the circuit to be tested passes through the current coil, it will produce two alternating magnetic flux passing through the aluminum disk. These two magnetic flux are the same in time, and they will produce vortex currents on the aluminum disk. Due to the interaction between the magnetic flux and the vortex, a rotating moment was generated, causing the aluminum disk to rotate. The magnetic flux of the brake magnet also passes through the aluminum disk. When the aluminum disk is rotated, the magnetic flux is cut, and a current is induced on the aluminum disk. The interaction between the current and the magnetic flux of the brake magnet produces a brake moment opposite to the rotation direction of the aluminum disk, so that the rotation speed of the aluminum disk is uniform. Its main structure included a voltage coil, a current coil, a rotating disc (aluminum disc), a rotating shaft, a brake magnet, a gear, a meter, etc. These components worked together to achieve the power measurement function, but there was no detailed illustration of the single-phase AC electric meter circuit diagram.

Can the 380V three-phase electric protection switch be reversed?
Reverse connection of 380V three-phase electric protection gate is risky and not recommended. Because in air-conditioning products, the only part that really used 380V voltage was usually the refrigerator. Other parts such as the computer board were 220V. If the neutral line and one of the live wires were connected in reverse, it could cause the 380V voltage to be directly input into the computer board, causing the pressure-resistant parts to burn. Moreover, many products 'neutral lines could cause the computer board to burn. In addition, the three phase lines of the three-phase power supply had a fixed phase sequence, and the air conditioner could not be reversed. Once it was reversed, it was easy to cause damage to the air conditioner.

How to adjust the moon phase on the moon phase watch
To adjust the moon phase function of the moon phase watch, you can follow the following steps:
1. Check the instruction manual or watch online educational videos: The watch's accessory instruction manual usually has teaching content on adjusting the moon phase function, and some brands will also publish educational videos on the Internet. Different brands had different designs, so looking at this information first would help to understand the precautions for adjusting the moon phase function. For example, some watches had time adjustment restrictions.
2. [The reference standard for determining the current moon phase: After mastering the adjustment method, you need to specify the position of the moon during the adjustment.] You can get accurate moon phase information by searching for related tools online (such as time and date). During the adjustment, the new moon could be used as a reference, and the position of the new moon hidden by the two moons on the moon phase plate could be used as the starting point. Then, according to the lunar calendar, it was judged how many days had passed since the last new moon, so as to adjust the correct moon phase. It could also be used as a reference. First, the full moon pattern was placed in the center of the moon phase window, and then adjusted according to the length of time from the last full moon. This could reduce the error.
3. Understand the accuracy of the moon phase function of the watch: The basic moon phase display system uses a 59-tooth gear, and the moon phase period is 29.5 days. However, the actual moon advancement period is not exactly 29.5 days, so the moon phase watch with a 59-tooth wheel will accumulate an error of one day every three months. Therefore, if the watch had this basic moon-phase function, it could be adjusted every three months to ensure the accuracy of the moon phase.
In addition, when adjusting the moon phase, you need to pay attention to avoid the time that is not suitable for the fast adjustment device. For most watches, the hour hand should avoid the range of 8 to 4 clockwise.(Because the gears of the quick dial button are tightly fitted from 8:00 pm to 4:00 am every day, the use of the quick dial button will easily cause the mechanical parts to malfunction.) Some special watches (such as Blancpain's moon phase watch) cannot use the moon phase quick dial button at 12:00 noon. In this case, the hour hand can be set back to 8:00 or after 4:00, and then use the quick dial button to adjust the date or moon phase, and then adjust the time.

How to adjust the moon phase of the Blancpain Moon Phase Watch
The steps to adjust the moon phase of the Blancpain Moon Phase Watch are as follows:
If it was a full calendar moon phase watch and it was a pointer type moon phase, the pointer must first be aimed at the middle of the full moon. The buttons to adjust the moon phase were mostly on the side of the case. Blancpain's full calendar moon phase watch was adjusted on the patent hidden adjustment button behind the ear. Generally, the date, week, and month were adjusted first, and finally the moon phase was adjusted. However, which button corresponded to the moon phase and which button corresponded to the date and month depended on the specific watch model. You needed to refer to the specific watch manual.
Take March 14th, 2017 (the 17th day of the lunar calendar) as an example. There are two days between the 15th day and the 15th day. At this time, you have to pay attention to the number of days ahead, and you have to adjust the calendar to the day before today (if today is the 5th day, then adjust it to the 4th day), and then press the adjust moon phase button according to the calculated number of days (in this case, it is 2 days, press twice).
If it was a Blancpain 5054 moon phase watch, its B button was responsible for the moon phase function. Generally, it was best to adjust it after the 15th day of the lunar calendar. Pressing it once would move the moon back by one day.
Check the full moon date of the previous month (according to the lunar calendar) and calculate the date to today (the date on the watch is the solar calendar). For example, today is July 15th, the last full moon was July 2nd, and today is 13 days. Press the adjustment button on the outside of the case (watches with moon phase function all have an embedded adjustment button, different brands have different positions), press the moon phase to rotate one day until the moon is in the middle of the moon phase plate, and then press this adjustment button 12 times.
