Outdoor switch cabinet circuit breaker action alarm device

Abstract

The invention discloses an outdoor switch cabinet circuit breaker action alarm device. The outdoor switch cabinet circuit breaker action alarm device includes a signal acquisition module, an input isolation module, a central processing module, an audio module, a nixie tube and indication light display module, a key input module, an alarm lamp output control module, an alarm indication module and a power source module for supplying power for the above modules. According to the outdoor switch cabinet circuit breaker action alarm device provided by the invention, the signal acquisition module comprises a plurality of circuit breaker fault sensors and a plurality of grounding fault sensors, wherein corresponding circuit breaker fault sensors acquire fault signals of corresponding switch cabinets, and corresponding grounding fault sensors acquire grounding fault signals of corresponding switch cabinets; the alarm indication module indicates circuit breaker faults and grounding faults of corresponding switch cabinets; the nixie tube is used for displaying the cabinet numbers of alarmed switch cabinets; and indication lights are utilized to distinguish circuit breaker faults and grounding faults; and therefore, healthy and safe operation of the switch cabinets can be ensured.

Description

technical field [0001] The invention relates to a switch cabinet monitoring device, in particular to an outdoor switch cabinet circuit breaker action alarm device. Background technique [0002] The urban power grid uses a large number of circuit breakers in the cabinet to protect the lines. When a fault occurs on a line, the inspectors need to open the cabinet door and check the status of the circuit breaker to check whether the circuit breaker is active. Since the urban network equipment is relatively scattered and some cabinets cannot be reached by vehicles, how to inspect the faulty line? Frontline personnel have to walk to each cabinet to open each cabinet to check, which is very time-consuming, seriously affects the progress of troubleshooting, and poses certain safety risks. Therefore, it is urgent to develop an outdoor switchgear circuit breaker alarm device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of...
