What are the Conditions for a High Voltage Switch Cabinet Circuit Breaker Control Circuit?
Whether it is high voltage switch cabinet or low voltage switch cabinet, if it is basically operated by the control of the circuit breaker, it is mainly used to control closing and opening. How is the circuit breaker control circuit of the high and low voltage switchgear designed? What are the requirements?
High Voltage Switch Cabinet
The control of the circuit breaker in the High Voltage Switch Cabinet is divided according to the control location, which can be simply divided into two kinds of local control and centralized control. , The task of opening the gate belongs to the local operation. China High Voltage Switch Cabinet Factory reminds that this control method not only saves costs, but also saves cables and secondary equipment.
The centralized control of the high-voltage switchgear circuit breaker is carried out in the main control room. In this control method, there is generally a long distance between the circuit breaker to be controlled and the main control room, which needs to be realized through an auxiliary circuit, and the control switch It is connected to the operating mechanism by a control cable.
There are many types of circuit breakers configured in high-voltage switchgear, and their operating mechanisms are also different, so there should be many different types of control circuits. The high-voltage switchgear factory reminds that although the types and models are different, their basic requirements are the same, that is, they can be manually closed and opened, and can also be automatically closed and opened by the relay protection and automatic device to avoid burning. Bad coil.
At the same time, as the circuit breaker control circuit of the high-voltage switchgear, it should also be able to indicate the status of the circuit breaker closing and opening positions; it can monitor the integrity of the control circuit and power supply; it has a mechanical or electrical anti-jump locking device; wiring is simple and reliable wait.
High-voltage switchgear factory reminds that if the above requirements can be met, it can meet the use requirements of high-voltage switchgear, and can better control the switchgear to make the correct action, so that the entire system remains stable.
