Abstract

The invention discloses an automatic protection device for an internal circuit of a transformer. The device comprises a transformer box body, wherein four supporting columns are arranged at a lower end of the transformer box body in an array mode, a transformer base is fixedly arranged at lower ends of the supporting columns, a voltage transformation cavity is formed in the transformer box body, and four iron core supporting columns are arranged in a lower wall of the voltage transformation cavity in an array mode. The device is advantaged in that the device is simple in structure, convenientto maintain and use, through a built-in heat dissipation device, internal heat dissipation of the transformer can be continuously performed, circuit protection structure, so the fire probability of the transformer is reduced, moreover, a built-in fire extinguishing device and a circuit protection structure can quickly perform fire extinguishing protection treatment of the transformer when the transformer is on fire, so flames can be quickly extinguished, and greater disasters are prevented.

Description

technical field [0001] The invention relates to the field of electric circuit device protection, in particular to an automatic protection device for an internal circuit of a transformer. Background technique [0002] With the development of electrification, electrical equipment has become an indispensable work equipment in people's production and life, and the normal operation of electrical equipment is inseparable from the transformer. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The components are primary coil, secondary coil and iron core. Their main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. However, when the transformer is overloaded or encounters lightning strikes, other faults such as coil short circuit are prone to occur. In turn, a fire is caused, which seriously endangers the safety of the environment. Today's transformer lines are ...
