What is the reason why a vacuum circuit breaker cannot close?
The vacuum circuit breaker requires a stable power supply for closing. If the power supply voltage is too low or the rectification part fails, it will cause the inability to close.
Comprehensive understanding of sulfur hexafluoride circuit breakers (SF6 circuit breakers)!
First, let's talk about SF6 circuit breakers. We know that the biggest difference between SF6 circuit breakers and vacuum circuit breakers is the difference in arc extinguishing media, so it is necessary to explain the properties of SF6 gas first.
What are the opening speed and closing speed of VS1 vacuum circuit breaker and their impact on the vacuum circuit breaker?
The opening speed and closing speed of the VS1 vacuum circuit breaker should be explained as the average speed. These parameters are often found in the factory test report of the vacuum circuit breaker. So what is the opening speed and what is the closing speed? Gate speed, what impact does it have on vacuum circuit breakers? Which speed range is the best for the vacuum circuit breaker? Let’s take a look at these questions together.
