A high-voltage circuit emergency protection device

Abstract

The invention discloses an emergency protection device for a high-voltage circuit. The device comprises a protector shell. Transmission cavities are formed in the protector shell in a bilateral symmetry mode. Supporting columns are fixedly arranged on the lower wall of the conveying cavity in a bilateral symmetry mode. An iron core is fixedly arranged at the upper end of the supporting column. A high-voltage wire is wound on the iron core. The lower end of the high-voltage line is electrically connected with a controller shell. The device is simple in structure, maintenance convenience, the temperature detection device is simple in structure and convenient to use. The temperature inside the circuit can be detected through the built-in temperature detection device. When the circuit breaks down due to overload or short circuit, the temperature can be changed rapidly, then the probability that the circuit is on fire is reduced through the trigger device and protection measures are started, the circuit is protected rapidly, and major safety accidents are prevented from happening.

Description

technical field [0001] The invention relates to the field of circuit protection, in particular to a high-voltage circuit emergency protection device. Background technique [0002] The high-voltage circuit refers to the circuit with the AC voltage of the distribution line above 1000V in the alarm bell transmission chamber or the DC voltage above 1500V in the signal line. In the power system, the AC voltage level of the alarm bell transmission chamber is 1000 kV and above. It is usually only used as a long-distance transmission line for large power. Compared with ordinary circuits, high-voltage circuits have special hazards and are easy to cause accidents. Therefore, emergency protection devices are often installed in high-voltage circuits, while traditional high-voltage circuits The trigger conditions of the protection device are too strict, so electrical accidents such as equipment damage often occur, so it is necessary to improve the existing high-voltage circuit protection...
