How to detect and use vacuum circuit breakers?

To detect a vacuum circuit breaker, a vacuum degree detector is needed. The vacuum degree detector, as its name implies, is an instrument for detecting the degree of vacuum. It is a high-voltage detection appliance commonly used in power systems, and the core component is a vacuum interrupter. So how can we use it for detection?

Anti-misoperation measures of high voltage isolating switch

The function of the high-voltage isolating switch is mainly to ensure the safety of the maintenance work of high-voltage electrical equipment, and to form a clear insulation gap between the equipment part that needs to be repaired and other live parts, so that the staff can safely repair the electrical equipment without affecting the other parts of the work.

Analysis of the Reasons for the Decrease of Vacuum Degree of High Voltage Vacuum Circuit Breaker

In the distribution network with voltage levels of 10kV and below, high-voltage vacuum circuit breakers have gradually replaced oil circuit breakers. High-voltage vacuum circuit breakers have the advantages of being suitable for frequent operation, long electrical life, small maintenance workload, flameproof, explosion-proof, and high operational reliability.

The fundamental difference between isolating switch and load switch

The structure of the high-voltage isolation switch is simple, and it can be used to isolate the high-voltage power supply to ensure the safety inspection of other equipment. However, it does not have a unique arc extinguishing configuration, so it is not allowed to operate under load.

The function and significance of high voltage vacuum circuit breaker

High-voltage vacuum circuit breaker is a circuit breaker that uses vacuum as insulation and arc extinguishing. Its components are: vacuum interrupter, operating mechanism (there are electromagnetic operating mechanism and spring operating mechanism), brackets and other parts.

Arc extinguishing principle of vacuum circuit breaker

The extinguishing of the vacuum arc is based on the use of the high dielectric strength of the high vacuum medium and the high diffusion speed of the arc products (charged particles and metal vapor) in this rarefied gas, so that the contact gap after the arc current crosses zero. It is achieved by the principle that the strength of the medium can be quickly recovered.

What is a high voltage load switch? How big is the breaking capacity?

The high-voltage load switch is an electrical appliance whose function is between the high-voltage circuit breaker and the high-voltage isolation switch. The high-voltage load switch is often used in series with the high-voltage fuse; it is used to control the power transformer.

Common sense of life of high voltage load switch

A high-voltage load switch is a high-voltage electrical device specially used to switch on and off load current. When equipped with a trip unit, it can also trip automatically under overload conditions. But it only has a simple fire extinguishing device, so it cannot cut off the short-circuit current.
