Automatic fire extinguishing type transformer

Abstract

The invention relates to an automatic fire extinguishing type transformer. The automatic fire extinguishing type transformer comprises a transformer shell, wherein a liquid storage box is arranged right above the transformer shell, insulating fire extinguishing liquid is stored in the liquid storage box, liquid discharge pipes are arranged at the bottom of the liquid storage tank, electromagneticvalves are arranged on the liquid discharge pipes, and spray heads are arranged at the lower ends of the liquid discharge pipes; a fire controller used for controlling the electromagnetic valves to beopened or closed is further arranged at the bottom of the liquid storage tank; and carbon dioxide is further stored in the inner cavity of the liquid storage tank, and the air pressure in the inner cavity of the liquid storage tank is 3-5 MPa. The automatic fire extinguishing type transformer is simple to install, maintain and operate, and can realize automatic fire extinguishing of the transformer; the transformer can immediately extinguish fire after ignition, so that the fire extinguishing efficiency is high; and the transformer does not generate a short circuit in the fire extinguishing process, so that further expansion of the fire can be avoided, the loss of the transformer is small, the subsequent maintenance or recovery of the transformer is facilitated, and the loss in the fire disaster is reduced.

Description

technical field [0001] The invention relates to an automatic fire extinguishing transformer, which belongs to the technical field of transformers. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil, iron core (magnetic core) and shell. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, 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.). [0003] When the current transformer catches ...

AI Technical Summary

Problems solved by technology

[0003] When the current transformer catches fire, only follow-up fire extinguishing schemes can be adopted. For example, firefighters use dry powder fire extinguishers for fire extinguishing operations. The fire extinguishing efficiency of the above fire extinguishing scheme is low, and the transformer will be almost completely lost. There is no need for maintenance, and it can only be recycled, so the loss will be relatively large
