China LW30 126 High Voltage SF6 Circuit Breaker Manufacturers, Suppliers, Factory

"High-voltage vacuum circuit breaker" is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in distribution network.

The vacuum interrupter (vacuum tube) of the vs1 vacuum circuit breaker is an important component of the vacuum circuit breaker. It can be said that it is the soul of the vacuum circuit breaker. Since the vacuum interrupter is composed of ceramics or glass, if it is once vacuumed during use If the ceramic or glass of the arc extinguishing chamber is broken, or there are cracks, it can cause air leakage in the vacuum arc extinguishing chamber. If there is air leakage, serious consequences will occur, so protecting the vacuum arc extinguishing chamber has become a top priority.

Installation location ZW32 vacuum circuit breaker boundary switches are usually installed on outdoor utility poles, so they are also called watchdog vacuum circuit breakers.

In modern electronic devices, load switches play a vital role as an important power management component. This article will explore the definition, working principle, application areas and importance of load switches in power management.

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?
