Abstract

The present invention provides a ring main unit cable joint temperature sensing system. The system comprises a data collector module (1) and a temperature sensor module (2); the data collector module(1) communicates with the temperature sensor module (2) through a mode; the temperature sensor module (2) comprises a temperature sensor (20), an antenna PCB (21) and an antenna metal radiation fin (23); and the temperature sensor (20) and the antenna metal radiation fin (23) are arranged on the antenna PCB (21). The ring main unit cable joint temperature sensing system provided by the invention achieves the temperature online sensing and monitoring function and changes the manual temperature measurement to automatic online monitoring so as to improve the usage safety of the ring main unit; and the temperature sensor employs a wireless mode for operation and can supply power without usage of batteries or other external power sources so as to further improve the safety of the monitoring system, and the ring main unit cable joint temperature sensing system is compact and reasonable in whole structure and easy to install and maintain.

Description

technical field [0001] The invention relates to a temperature sensing system, in particular to a temperature sensing system for a cable joint of a ring network cabinet, and in particular to a wireless temperature sensing system for a cable joint of a ring network cabinet. Background technique [0002] Ring Main Unit (Ring Main Unit) is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metallic insulated cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and The fuse has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] Since the ring main unit is in the key position of th...
