Fault removal protection device of high-voltage cable

Abstract

The invention discloses a high-voltage cable obstacle removal protection device, which comprises a device main body surrounded by an aluminum sheath, one side of the device main body is provided with a firewall, and the other opposite side of the device main body is provided with a branch box. Shutters are arranged around the box, branch openings are set inside the branch box, cable clamps are installed around the main body of the device except the bottom, circuit breakers and alarms are installed on the top of the main body of the device, and both ends of the main body of the device are equipped with Rotating shaft, the top of the rotating shaft is equipped with a fire extinguishing device, the two opposite sides of the main body of the device are equipped with manhole wells, the inside of the main body of the device is set with grooves, the outside of the grooves is covered with insulating materials, and the inside of the main body of the device is equipped with steel plates. The interior of the main body of the device is equipped with a return line and a temperature control device. This kind of high-voltage cable obstacle removal protection device can reduce the induced current when a short-circuit fault occurs and can keep the surrounding environment of the cable constant.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high-voltage cable obstacle removal protection device. Background technique [0002] High-voltage cables refer to power cables used to transmit power between 10KV-35KV. They are mostly used in main roads for power transmission. They have high power supply reliability and can be applied to special places. They are laid underground and basically do not occupy ground space. The production and life have brought convenience. [0003] However, the existing high-voltage cables are affected by the environment of the laying site, and the cables are prone to accidents, such as fires, etc., and the fault side finds and repairs take a long time, which brings great hidden dangers to people's lives, and the cables are not easy to branch underground. It is easy to cause a short circuit between cables and cause economic losses, so at this time, the high-voltage cable obstacle rem...
