Abstract
Description
technical field
[0001] The invention relates to an isolating switch with a counter, belonging to the technical field of power supply devices. Background technique
[0002] During the manual operation of the isolating switch, due to differences in the habits, operation methods and strength of different operators, it is easy to cause accidental closing of the knife switch due to incomplete closing, resulting in false connection between the knife switch insurance and the contact point, or incomplete breaking. , Although the closing is not in place, although the circuit can be temporarily turned on, as the load increases, it is easy to cause overheating and burning of the dynamic and static contacts, and accidental closing is likely to cause personal injury to maintenance personnel. At the same time, when the isolation switch is frequently operated, it is easy to cause equipment aging and performance degradation. The isolation switch is different from equipment such as transform...
