Transformer fireproof device with heat dissipation function

Abstract

The invention discloses a transformer fireproof device with a heat dissipation function. The transformer fireproof device comprises a transformer box body and a mounting base located at the bottom endof the transformer box body. The transformer box body is of a cavity structure with a lateral opening. A fireproof mechanism is arranged at the top end in the transformer box body; the fireproof mechanism comprises a first connecting block and a second connecting block which are transversely arranged and symmetrically arranged on the two sides in the transformer box body, chutes are formed in thesides, close to each other, of the first connecting block and the second connecting block, a telescopic plate connected with the two chutes is arranged in the transformer box body, and an obliquely-arranged movable rod is arranged at the bottom end of the telescopic plate. The transformer fireproof device has the beneficial effects that when the telescopic plate stretches out and draws back, sandcan leak out of the bottom of a compartment, fire is extinguished, and the fireproof effect is achieved; the interior of the transformer box body communicates with the outside, so that explosion is prevented; and due to the design of a heat dissipation mechanism, the temperature generated by the heating body is reduced, and heat in the transformer can be reduced.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer fire protection device with heat dissipation function. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic Saturated transformers), etc., can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument Use transformers, electronic transformers, reactors, transformers, etc.), circuit symbols often use T as the b...

AI Technical Summary

Problems solved by technology

[0003] Many transformers in the prior art are installed in the transformer box. Installing the transformer in the transformer box can increase safety and aesthetics, but the heat dissipation will be poor, and the transformer will generate a lot of heat during operation. If If the transformer is not dissipated, the service life of the transformer will be reduced if it is used for a long time. In severe cases, it may cause a fire, which brings economic losses to people and is not convenient to use. The box-type transformer in the prior art does not have an automatic fire extinguishing device, and a fire occurs in the transformer. It is difficult to extinguish the fire in time, causing life threat and property damage
