Problems solved by technology

Electrical equipment in operation usually works at high voltage and high current. During the long-term operation of the equipment, some defects such as surface oxidation corrosion, loose fastening bolts, and aging of contacts and busbar connections will lead to excessive contact resistance. Large and hot, and the temperature of these hot parts is difficult to monitor, the general manual inspection and temperature measurement is more troublesome, and it is impossible to measure the temperature in time, which eventually leads to combustion, explosion or even equipment damage or quality accident due to excessive temperature

Abstract

The invention relates to the field of cabinet temperature measurement and particularly relates to a switch cabinet wireless temperature measuring device. A switch cabinet comprises a joint, and the position of the joint is the joint position of a cable. The position of the joint is equipped with a wireless temperature measurement part which is a wireless temperature measurement sensor. The wireless temperature measurement sensor is a watch strap type wireless temperature measurement sensor whose wireless temperature measurement probe is close to the joint position. The wireless temperature measurement part can measure real-time temperature and transmit the real-time temperature to a communication management machine and a host machine. The host machine can collect and record fed temperature. The advanced storage technology is used, and set parameters can be saved after power down. A self-locking panel type mounting mechanism is adopted, the wire connection is simple, and the disassembly and assembly are very convenient. The device has the advantages of a small size, a small occupation space and high applicability and is equipped with a standard opening size.

Description

technical field [0001] The invention relates to the field of temperature measurement of switch cabinets, in particular to a wireless temperature measurement device for switch cabinets. Background technique [0002] In industrial systems, for the safe operation of power equipment, the important principle is: effective prediction in advance and preventive measures, not just passive responses. Temperature is an important parameter that characterizes the normal operation of equipment. In order to avoid emergencies caused by equipment heating, automatic temperature monitoring has become an important part of industrial safety production. Contacts and joints in electrical equipment are an important hidden danger to the safety of the power grid. According to statistics, faults mainly occur in important equipment such as switch cabinet moving contacts, static contacts, cable joints, bus joints, and knife switches. Electrical equipment in operation usually works at high voltage and ...
