Temperature monitoring device and method for passive wireless switch device of switch cabinet

Abstract

The invention discloses a temperature monitoring device and method for a passive wireless switch device of a switch cabinet. The device comprises at least one first temperature sensor used for carrying out temperature acquisition on a bus bar in the switch cabinet, at least one twelve-temperature sensor used for carrying out temperature acquisition on a moving contact of a circuit breaker in the switch cabinet, and at least one third temperature sensor used for carrying out temperature acquisition on an outdoor knife switch, the three temperature sensors are in wireless communication connection with the relay modules respectively, and the relay modules are connected with a background monitoring system or a remote monitoring system in a wireless communication mode after being subjected to ad hoc networking. According to the present invention, the problem that it is difficult to conveniently and accurately monitor the temperature of tje bus bar in tje switch cabinet, the moving and static contacts deeply hidden in a circuit breaker shell and a disconnecting link arranged on an outdoor power transmission tower by manually holding a thermal imager or a contact type temperature sensor at present, is solved.

Description

Technical field: [0001] The invention relates to the technical field of power equipment operation monitoring, in particular to a passive wireless switchgear temperature monitoring device and method for a switchgear. Background technique: [0002] With the development of smart grid, real-time acquisition of status information of electrical equipment is very critical in the intelligent construction of power system. High-voltage switchgear is one of the important equipment in the power system. Whether it can be operated reliably is a very critical factor in the safe production of substations and the reliable operation of electric power. There are many scattered parts inside the switchgear, such as circuit breakers, bus bars, incoming and outgoing lines, etc. Due to the tight internal space of the switchgear due to the volume limit, the current as the intermediary of the incoming and outgoing lines is generally large. The high current often causes the temperature rise of the sw...
