What is a low-voltage motor? Presumably, most electricians are familiar with it. The structure of the low-voltage motor is relatively simple and inexpensive, it is more convenient to use, and it is widely used in production and life. In large-scale chemical projects, there are many types of low-voltage motors, a large number, different control methods, and complex control requirements. The design of the control circuit of the motor plays a particularly important role in the operation, safety and value of the entire motor, especially the low-voltage motor. So in the motor circuit design interrupter, contactor, thermal relay, how should the three be selected? Let's let xiaobian give you a brief talk about it!
1. What are the main electrical components used in the starting circuit of the low-voltage motor?
2. What are the key points for the selection of the low-voltage motor start loop interrupter?
3. How to select the contactor in the starting loop of the low-voltage motor?
4. How to choose the thermal relay in the starting circuit of the low-voltage motor?
5. Motor, circuit breaker, contactor, thermal relay distribution table:
