Abstract

The invention discloses a self-recovery short-circuit protection device. The device comprises a shell. Two ends of the shell are symmetrically embedded with. A wire is connected between the two metalconnecting pipes, a warning lamp is embedded in the side wall of the shell in a surrounding mode, a positive electrode wire and a negative electrode wire are connected to the warning lamp, a vacuum cavity is formed in the shell, and two semiconductor rings and two magnetizing coils are symmetrically installed on the two side walls of the vacuum cavity. The functions of short-circuit protection andshort-circuit self-recovery are achieved through demagnetization separation and magnetization attraction of the magnetization conductive plate in the vacuum cavity, the service life of the device isprolonged through the semiconductor refrigeration ring, and normal work of the magnetization coil and the semiconductor refrigeration ring is guaranteed through semiconductor ring rectification alternating current.

Description

technical field [0001] The invention relates to the field of electricity safety, in particular to a self-restoring short-circuit protection device. Background technique [0002] In order to protect the safety of electrical equipment and personnel in the power line, a short-circuit protection device will be installed on the power line to prevent the short circuit of the line from causing electric fire or electric injury. [0003] The existing short-circuit protection device cuts off the circuit after the protection action is triggered, but cannot recover in time, so that the power line is in a power-off state for a long time, making other electrical equipment on the power line unusable, and the existing device cannot be used after the short circuit occurs. Due to the high temperature of the circuit caused by the short circuit, the life of the internal circuit of the protection device decreases with the increase of the number of protections. Contents of the invention [000...
