Cause analysis: In the normal operating state of the circuit breaker, the circuit breaker does not open when there is no external operating power supply and mechanical opening action. After confirming that there is no misoperation, check the secondary circuit and the operating mechanism. It was found that the auxiliary switch contacts in the operating mechanism box were short-circuited, and the opening power supply was connected to the opening coil through the short-circuit point, resulting in false opening.

In the previous article, we talked about the mechanical atresia (lock) of the VS1 vacuum section device. What is the role of the fixed spindle of the device? ——It is a mechanical atresia between fixed and high -voltage forms. Why must you choose a mechanical atresia?

Speaking of this problem, let’s first understand what overvoltage is: Overvoltage refers to the long-term voltage fluctuation phenomenon in which the root mean square value of the AC voltage under power frequency increases, exceeds 10% of the rated value, and lasts for more than 1 minute; The appearance of voltage is usually the result of a moment of load switching. Occurs when inductive or capacitive loads are connected or disconnected during normal use. What are its occurrences?

Vacuum Circuit Breaker is an indoor switchgear designed for power systems, which can be used as a protection and control unit in power grid equipment and industrial power applications. It plays an important role in handling various loads, frequent operations and repeated short-circuit breaking.
