Description

A comprehensive automatic substation temperature detection system

technical field

The utility model relates to the field of power supply facilities and equipment, in particular to a comprehensive automatic substation temperature monitoring system.

Background technique

In the detection of electric power equipment, it is necessary to frequently measure the temperature of various components of electric power equipment, such as the temperature of the stator and rotor of the generator, the temperature of the transformer, and the internal temperature of the switch cabinet. The power transmission and distribution equipment in the substation is in high-voltage and high-current operation for a long time, which is very prone to problems such as oxidation and corrosion on the surface of the equipment, aging of the crimping of the busbar, and loosening of the fastening bolts. These problems can easily cause heating of the substation equipment. If reliable monitoring methods are used, the temperature rise will increase, the equipment will be overheated and the equipment will be burned, resulting in power supply interruption or serious accidents, and serious economic losses. Therefore, effective temperature monitoring of substation equipment has important practical significance. Because the high-voltage power equipment, high-voltage cables and switchgear in the substation are in the environment of high voltage, high current, strong magnetic field and extremely strong electromagnetic interference, it is difficult to manually inspect and measure the temperature, and it is impossible to use conventional temperature measurement methods to monitor the temperature. With the development of unattended integrated automatic substations in the power system, a reliable temperature real-time monitoring system is particularly important.
