Abstract

The embodiment of the invention discloses a device for temperature measurement and fault diagnosis of a switch cabinet, and is used for solving the technical problems that the sensor installation process of an existing device for temperature measurement and fault diagnosis of a switch cabinet is complicated, power outage of a power supply system is needed to perform installation operation, all key electric contacts in the switch cabinet all need to be equipped with a temperature sensor, and the cost is high. The device for temperature measurement and fault diagnosis of the switch cabinet includes magnetic type wireless temperature sensors and a wireless receiving display terminal, wherein the magnetic type wireless temperature sensors are arranged outside a cabinet body of the switch cabinet, and are connected with the wireless receiving display terminal through wireless signals.

Description

technical field [0001] The invention relates to the field of temperature measurement fault diagnosis of electric switch cabinets, in particular to a device for temperature measurement and fault diagnosis of switch cabinets. Background technique [0002] Switchgear is an important power equipment in the power system. During the long-term operation of the equipment, some dangerous hot spots in the switchgear, such as busbar contacts, high-voltage cable joints, contact points of circuit breaker contacts and sliding contact points, etc., will cause excessive contact resistance due to aging or other reasons, resulting in heating. If it is too large, it will directly affect the normal operation of the equipment and even cause accidents. [0003] The high-voltage switchgear equipment currently in operation is generally not equipped with a temperature monitoring function. When the equipment malfunctions and the temperature rises abnormally, the management personnel cannot be inform...
