How to judge whether the arc extinguishing chamber of vs1 vacuum circuit breaker is leaking?

At Timetric Electric, we know how important the vacuum interrupter of the VS1 vacuum circuit breaker is to the performance of the equipment. Let’s discuss how to determine whether there is a leakage problem in the VS1 vacuum circuit breaker and how to solve it.

1. Visual inspection method: For the vacuum bubble in the glass shell, we can initially determine whether there is an air leakage problem through visual inspection. Normally, the internal components of the vacuum interrupter should have a bright surface color and should emit blue arc light when the current is turned on and off. When the vacuum degree drops severely, the internal color may change to gray or dark red. Although this method is simple, it

The judgment results may not be accurate enough and may easily lead to misjudgments.

2. Vacuum degree detection method: Using the vacuum degree detection method, detection can be performed during a power outage. However, this method can only detect air leakage during a power outage, and there is still the possibility of air leakage during the detection period.

3. Benefit analysis: Through periodic vacuum testing of the vacuum bubble, the air leakage of the vacuum bubble can be evaluated. However, this method takes a long time and may cause power loss in the device.

4. Vacuum bubble method: By wrapping a double-layer metal mesh outside the vacuum bubble and covering it with a glass cover, air leakage can be detected in time and relevant personnel can be notified through the alarm circuit. This method does not require power outages, is economical and simple, and is applicable to all vacuoles.

5. Power frequency withstand voltage method: Use the power frequency withstand voltage method to test. If the test passes, it proves that the vacuum interrupter does not leak. If the current pointer swings or swings slightly during the power frequency withstand voltage process, it may be that there is an air leakage problem in the vacuum interrupter and needs to be replaced in time.

In short, the above method can be used to detect air leakage in the vacuum interrupter of the VS1 vacuum circuit breaker. Timetric Electric is committed to providing
