Automatic protection device for transformer

Abstract

The invention discloses an automatic protection device for a transformer; the device comprises a bottom plate, the top of the bottom plate is provided with a transformer, a binding post at the top of the transformer is connected with two insulated wires used for power transmission, the top parts, close to the two sides, of the bottom plate are fixedly provided with mounting strips, and the outer walls of the two mounting strips are provided with sliding grooves. Two sliding grooves are formed in the bottom plate, lifting blocks are vertically installed in the two sliding grooves in a sliding mode, springs are connected to the tops of the two lifting blocks and the inner walls of the two sliding grooves correspondingly, cutting knives are installed at the bottoms of the two lifting blocks, and grooves allowing the cutting knives to penetrate through are formed in the positions, located below the two cutting knives, of the top of the bottom plate correspondingly. Through cooperation of the structures, when the transformer encounters a fire emergency situation, power-off protection can be conducted on the transformer in the first time, the effect of conducting processing protection on the transformer in time is achieved, secondary accidents are prevented from being caused, and the protection performance of the transformer is further improved.

Description

technical field [0001] The invention relates to the technical field of transformer protection, in particular to an automatic transformer protection device. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. [0003] Although the existing transformer is connected to the transformer by introducing insulated wires, with long-term use, the connection between the transformer and the wires may be damaged due to the aging of the insulating material or short circuit, etc., and even burns and catches fire. If it cannot be processed in time, it will cause great safety hazards and lead to accidents. Contents of the invention [0004] The purpose of the present invention is to provide an automatic protection device for transformers. When the transformer encounters an emergency situation of fire, it can immed...

[0003] Although the existing transformer is connected to the transformer by introducing insulated wires, with long-term use, the connection between the transformer and the wires may be damaged due to the aging of the insulating material or short circuit, etc., and even burns and catches fire. If it cannot be dealt with in time, it will cause great safety hazards and lead to accidents.
