Abstract

The invention discloses a temperature monitoring device of a switch cabinet, and relates to the switch cabinet. The temperature monitoring device of the switch cabinet comprises a temperature sensor (1), a multimode optical fiber (2), an optical fiber temperature monitor (3), an alarm apparatus (4) and a line detection network device (5), wherein the temperature sensor (1) is connected with the optical fiber temperature monitor (3) through the multimode optical fiber (2); the optical fiber temperature monitor (3) is connected with the alarm apparatus (4); and the alarm apparatus (4) is connected with the line detection network device (5). The optical fiber is insulated stably and reliably, and signal transmission is not affected by the environment or electromagnetism. An optical fiber temperature sensor can be directly arranged on a point to be tested inside the switch cabinet to transmit a temperature signal to low potential, so that online monitoring of operating temperature is achieved.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a switch cabinet temperature monitoring device. Background technique [0002] During the long-term operation of the switchgear, the contact of the circuit breaker in the cabinet and the connection of the bus bar will cause poor contact and local overheating due to oxidation, loosening and other reasons. The switchgear cannot operate normally. As disclosed in the application document of Chinese application number 201110356369.2, a switchgear temperature monitoring device includes a data acquisition module, an A / D conversion module, a single-chip processing module and a host computer connected in sequence, and also includes a single-chip processing module. Display module and alarm module. It solves the problem that the temperature of the switchgear needs to be inspected manually in the prior art, realizes the intelligent monitoring of the temperature of the switchgear, gets rid of the manual...
