The reverse rotation control circuit was a circuit used to control the forward and reverse rotation of the motor. The working principle was as follows: - ** Contactor Interlock Positive and Negative Rotation Control Circuit **: - ** Forward Rotation **: Press the Forward Rotation Start button (such as SSB2), and the coil of the Forward Rotation Contactor (such as Km1) will be energized. The Km1 auxiliary normally open contact is closed to achieve self-locking, ensuring that the circuit remains connected after the button is released; the Km1 auxiliary normally closed contact is disconnected and interlocked with the reversing contact (Km2) coil to prevent simultaneous power-on. At the same time, the main contact of Km1 was closed, and the motor was powered up and began to rotate forward. - ** Reverse **: Press the reverse start button (like SSB3), and the Km2 coil will be energized. The Km2 auxiliary normally open contact is closed and self-locked, and the Km2 auxiliary normally closed contact is disconnected, causing the Km1 coil to lose power (forming an interlocked). The Km1 main contact is reset, the Km2 main contact is closed, and the motor runs in reverse. - ** Double Interlock Positive and Negative Rotation Control Circuit of the Button-Contactor **: Add the Button-Contactor Interlock to the Contactor Interlock. The normally closed contact of the reverse start button is connected in series with the coil of the contactors that control the forward rotation, and the normally closed contact of the forward start button is connected in series with the coil of the contactors that control the reverse rotation. This was equivalent to double insurance, further ensuring that the positive and reverse contactors would not be energized at the same time, improving the safety and reliability of the circuit. The principle of the positive and negative rotation control in the ladder diagram was similar: - Two start-stop circuits were used to control the forward and reverse rotation of the motor. Pressing the forward start button (such as SSB2), the corresponding input point (such as X0) will turn ON, and its normally open contact will be connected, so that the coil of the output point (such as Y0) will be "energized" and self-protect, so that the coil of the forward rotating contactors (such as KM1) will be energized, and the motor will rotate forward. - Pressing the stop button (such as SSB1), the corresponding input point (such as X2) will turn ON, and its normally closed contact will be disconnected, causing the coil of the forward output point (such as Y0) to "lose power" and the motor will stop running. - In order to ensure that the forward and reverse rotation do not work at the same time, the normally closed contacts of the forward rotation output point (such as Y0) and the reverse rotation output point (such as Y1) are connected in series with each other's coil to achieve interlocked connection; and the button is interlocked, that is, the normally closed point of the reverse rotation start button is connected in series with the coil of the output point (such as Y0) that controls the forward rotation, and the normally closed contact of the forward rotation start button is connected in series with the coil of the output point (such as Y1) that controls the reverse rotation. In this way, when the motor was rotating forward, if it wanted to change to reverse operation, it could directly press the reverse start button without pressing the stop button, and through the switching of the contacts, it could realize forward transformation and reverse rotation. In addition, there are often overload protection components in the circuit, such as thermal relay (FT). When the induction motor is seriously overloaded for a long time, after a certain delay, the thermal relay will act, and its normally closed contact will be broken. When it is connected in series with the coil of the contactors, it can make the coil of the contactors cut off, and the motor will stop running, playing a protective role. Some thermal relay needed to be manually reset, and some had an automatic reset function. During the circuit connection and use, the connection position of the contacts needed to be reasonably arranged according to its characteristics to ensure safe operation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a plot of a novel about a one-stop funeral service: In a seemingly ordinary but depressing city, there was a woman named Shen Ting. She had been treated coldly and misunderstood by her family for a long time. After she was diagnosed with depression and became ambipolar, she was disheartened and decided to arrange for her death. She booked a luxurious one-stop funeral service on an APP called " Are you dead?" The one-stop funeral service in this APP sounded very comprehensive. They could even choose their favorite " ferryman " to send them on their last journey. When she began to deal with her belongings, burn her photo album, clothes, etc., erase the traces in the family and leave the house, the story of the one-stop funeral service began to unfold. The customer service had communicated with her many times about the "ferryman" candidate. First, the originally selected "ferryman" resigned but did not remove the photo. After re-selection, he was told to replace him. At this time, Shen Ting had already begun to swallow sleeping pills. She was bent on dying, but the arrangements for the funeral service were frequently in trouble. Her road to death was constantly interrupted by matters related to funeral services, such as various inquiries and negotiations from customer service, from service content, price discounts to specific operational procedures. Although Shen Ting was in such a desperate situation, the funeral service was like an invisible hand that maintained a connection between her and the world. It made the process of her seeking death complicated and complicated. At the same time, it also reflected the trace of attachment to life in her heart and the resistance to the absurdity of the world. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
