Why do switch cabinets need to monitor temperature
It is an important device in the power system and widely used in various industries. There are many heat dissipation components in the switchgear, and the temperature is generally high. Imidlertid, existing switchgear generally has poor heat dissipation and high temperature, especially in some areas or seasons with high temperatures. It is easy to cause damage to components and accidents in the switchgear due to high temperature.

With the advancement of intelligent power systems, higher requirements have been put forward for status monitoring of substation switchgear. The existing comprehensive status monitoring device for substation switchgear still faces problems of incomplete monitoring system and unstable signal transmission.

Due to the complex structure of switchgear, existing switchgear status monitoring systems mainly focus on monitoring the status of a certain aspect of the switchgear, and have not achieved multi-dimensional status monitoring of the switchgear. Due to strong electromagnetic interference inside the switchgear, the data transmission of status monitoring is easily affected, making it difficult to obtain effective monitoring data and operating status, which increases the difficulty of monitoring and maintenance of the switchgear.

Overheating faults of high-voltage switchgear have always been common in high-voltage electrical appliances, especially during high temperatures such as summer, when overheating faults occur frequently. No matter which material is used for power transmission, there is always a material resistance value present. Under the action of current and voltage, the equipment will generate normal heat loss. Imidlertid, when the resistance of a connector in the current circuit is too high, the gap in that part will discharge, and the amount of heat generated will increase sharply. When the normal heat dissipation of the switchgear cannot dissipate the heat quickly, the temperature of this part will rise abnormally. The occurrence of overheating faults also poses a potential threat to the personal safety of substation operation and maintenance personnel.

Derfor, it is urgent to obtain the temperature field of the overheating fault of the high-voltage switchgear, so as to accurately determine its status, replace the faulty equipment in a timely manner, and avoid unnecessary losses.
