Disconnecting switch with counters

Abstract

The invention discloses a disconnecting switch with counters.The disconnecting switch comprises a base, a left gate, a right gate, a disconnecting link and a disconnecting link state indicating device; the disconnecting link and the right gate are hinged together; the disconnecting link state indicating device comprises a first button, a second button, a first indicator light and a second indicator light, wherein the first indicator light and the second indicator light are electrically connected with the first button and the second button respectively; the disconnecting link is provided with a left ejector rod and a second ejector rod.The disconnecting switch is characterized by further comprising the first counter and the second counter, and the first counter and the second counter are connected with the first button and the second button respectively and used for recording the number of in-place switch-on times and the number of thorough switch-off times of the disconnecting switch.The counters are arranged on the disconnecting switch to record the number of in-place switch-on times and the number of thorough switch-off times, and operation standardization of workers is supervised by comparing the two kinds of data, so that the safety of the disconnecting switch is improved, and the disconnecting switch has good application prospects.

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...
