Mining flame-proof transformer

Abstract

The invention belongs to the technical field of transformer protection, and particularly relates to a mining flame-proof transformer which comprises a transformer body, a protective door is rotationally connected to the outer side of the transformer body, an index display screen is fixedly arranged on the outer surface of the protective door, control keys are fixedly arranged at the bottom of the index display screen, and a handle is fixedly connected to the outer surface of the protective door. The interior of the transformer is fixedly connected with an explosion-proof steel plate, the interior of the explosion-proof steel plate is fixedly connected with a buffer net, the interior of the inner wall of the transformer is fixedly connected with connecting frames, flame-retardant materials are fixedly installed between the connecting frames, and the interior of the explosion-proof steel plate is fixedly connected with a cross-shaped supporting frame. According to the mining flame-proof transformer, the explosion-proof steel plates are arranged inside, so that the situation that internal transformer parts are affected to the exterior of the transformer when explosion occurs is avoided, meanwhile, the flame-retardant materials are arranged, the situation that spontaneous combustion occurs in the transformer and then diffusion to an external circuit is avoided, and the safety of external connecting devices is guaranteed.

Description

technical field [0001] The invention relates to the technical field of transformer protection, in particular to a mine flameproof transformer. 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 transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it 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 transformers, electronic transformers , reactors, transformers, etc.). A transformer is a device tha...
