Short-circuit prevention protection device for high-voltage electric appliance

Abstract

The invention discloses an anti-short-circuit protection device for a high-voltage electric appliance. The device comprises a main seat, an inner seat is fixedly arranged in the main seat, and a cooling mechanism and a partition mechanism are arranged between the main seat and the inner seat. The inner seat with an opening in an upper end is arranged in the main seat, an operation table and a circuit closer are movably installed through the inner seat, and a switch type power supply capable of abutting against the circuit closer is installed in the inner seat; a cooling box, an evaporation pipe and an expansion air bag which are connected with one another are arranged in the main seat so that an evaporation liquid can be quickly evaporated when absorbing excessive heat to reach an evaporation point, and the expansion air bag expands to drive the circuit closer to be separated from the power supply; a driving rack and a driven flat gear which are in meshed connection are utilized so that a driving wind wheel and a driven wind wheel can drive high-temperature hot air in the inner seat to be rapidly exhausted in a rotating process; and a driving bevel gear and a driven bevel gear which are connected in a meshed mode are used for driving a pressurizing wind wheel to rotate at a high speed, and a cooling and heat dissipation protection effect is achieved by continuously supplementing low-temperature cold air.

Description

technical field [0001] The invention relates to the technical field of electrical appliance application management and protection, in particular to an anti-short circuit protection device for high-voltage electrical appliances. Background technique [0002] Because of the development of the times, many fields of production and life have gradually realized the use of intelligent electronic control equipment, but because of the long service life and high frequency of use, these electronic control equipment have to face high voltage risks. [0003] Because of unreasonable usage habits, the electronic control equipment is in the power-on standby state for a long time. Short circuit accidents are very easy to occur when the control equipment is connected to the electricity, which will cause a large amount of high-temperature heat to be generated in a very short period of time. If the power-off protection is not performed in time, and the high-temperature heat in the electronic co...
