Vacuum circuit breaker has short arc burning time, high insulation strength, high electrical life, small contact distance and stroke, small operation energy, so the mechanical life is also high. In the daily operation, the maintenance workload is very small, the main inspection mechanism of the moving parts wear, fasteners are loose, remove the dust on the insulation surface, inject some grease in the active part, etc.
In the spring inspection preventive test, the DC resistance test of the switch should be compared with the historical data, and the problem should be dealt with and replaced in time. The power frequency voltage test of the fracture is an effective method to check whether the vacuum bubble leaks. (Indoor vacuum circuit breaker can learn from the color of the flash in the vacuum bubble when the load is off to initially judge the vacuum degree of the vacuum bubble. Dark red indicates that the vacuum degree is reduced, and light blue indicates that the vacuum degree is good.) During protection and colonization verification, low voltage off closing test is carried out on the circuit breaker to check whether the switch can operate reliably when the voltage is reduced when the busbar is faulty.
The operating mechanism is mainly composed of energy storage mechanism, locking mechanism, opening spring, switching spindle, buffer and control device.
