High voltage switchgear refers to the switchgear equipment working in high voltage and high current environment. Due to the particularity of the working environment, the general high voltage switchgear has very high technology and safety requirements. In the long-term operation process, it has the following characteristics:

(1) Intrinsic security. The high voltage switch cabinet is made of optical fiber sensor, optical fiber sensor is made of new insulating materials, and can carry out real-time monitoring of the power supply situation on the site, with extremely high safety performance. In addition, high voltage switchgear also has high stability, will not be affected by electromagnetic interference.

(2) Real-time monitoring. High voltage switchgear can realize real-time monitoring effect, can detect and control the power system in the case of unattended, saving manpower and material resources.

(3) Flexible and advanced. Flexible and advanced on the one hand means that the whole high voltage switchgear system can not only measure the temperature of a single switchgear, but also can measure the temperature of multiple switchgear at the same time. On the other hand, it can not only display the temperature of each switch cabinet one by one, but also collect all the data and upload it to the monitoring computer for unified management. In addition, the high voltage switchgear can not only display the temperature of the measured point, but also achieve the effect of temperature alarm through a series of means.
