What is the necessity of temperature monitoring for low-voltage distribution cabinet?

Low voltage distribution cabinet is a kind of electrical equipment. The external line enters the main control switch in the cabinet first, and then enters the sub control switch. Each sub circuit is set according to its needs. For example, instruments, automatic control, motor magnetic switches, various AC contactors, etc., some are also equipped with high-voltage room and low-voltage room switch cabinets, high-voltage buses, such as power plants, etc., and some are also equipped with low cycle load shedding for main equipment.

As an important equipment to ensure the safe operation of the system, the overheating of the internal conductive connection of the low-voltage distribution cabinet will cause damage to the electrical equipment, and even more serious accidents such as fire may occur. Therefore, it is necessary to monitor the temperature of the high-voltage switchgear.

According to the characteristics of low-voltage distribution cabinet temperature measurement different from ordinary temperature measurement system, a wireless temperature measurement system using energy supply CT for power supply, wireless transmission mode and point to multipoint wireless networking is developed, and corresponding anti-interference measures are taken for the software and hardware of the whole system to ensure the reliability of the system.
