A transformer automatic protection device

Abstract

The invention discloses an automatic protection device for a transformer, which comprises a bottom plate, a transformer is installed on the top of the bottom plate, two insulated wires for power transmission are connected to the top terminal of the transformer, and the tops of the two sides of the bottom plate are close to each other. Mounting strips are fixed, the outer walls of the two mounting strips are provided with chutes, and lifting blocks are vertically slid in the two chutes, and the tops of the two lifting blocks are respectively connected to the inner walls of the two chutes. Springs are connected, cutting knives are installed on the bottoms of the two lifting blocks, and slots for the cutting knives to pass through are provided on the top of the base plate below the two cutting knives. Through the cooperation between the structures, the present invention can protect the transformer from power failure at the first time when the transformer encounters an emergency situation of fire, so as to achieve the effect of immediately processing and protecting it, preventing it from causing secondary accidents, and further Improve the protection performance of the transformer.

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...
