Problems solved by technology

[0004] However, after a nationwide accident investigation, it was found that the simple method of oil discharge and nitrogen filling still has insufficient fire control, and it cannot quickly control the fire and extinguish the fire; rapid fire control can avoid further expansion of losses and reduce damage.

Abstract

The invention discloses a fire extinguishing system for a main transformer. The fire extinguishing system can more quickly and efficiently control a fire behavior of a transformer, reduce the fire loss and reduce the harm. The fire extinguishing system comprises fixed fire-fighting assemblies arranged on the left side and the right side of a transformer body 1 respectively, wherein each fixed fire-fighting assembly comprises a heat dissipation wall body, and heat dissipation fans are uniformly distributed on the heat dissipation wall body; a heat dissipation water pipe is distributed on each heat dissipation wall body; a water inlet of each heat dissipation water pipe is connected to a drainage outlet of a fire pump I of a fire water tank I, and each fire pump I is located in the corresponding fire water tank I; a fire-fighting water spraying pipe I is further arranged on each fire pump I, and fixed fire-fighting nozzle assemblies used for spraying water towards the transformer body are distributed on each fire-fighting water spraying pipe I; and fire-fighting water collecting grooves are annularly distributed around the transformer body, a fire-fighting oil collecting groove is formed in the distal position away from the transformer body, and an oil discharge outlet is further formed in the transformer body and is provided with an oil discharge pipe used for leading to the fire-fighting oil collecting groove.

Description

technical field [0001] The invention relates to a fire-fighting system for a main transformer, and is particularly used for fire-extinguishing and fire-fighting of a transformer in a power system. 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 with transformers, electronic transformers, reactors, transformers, etc.).
