Fire extinguishing system for outdoor transformer substation

Abstract

The invention discloses a fire extinguishing system for an outdoor transformer substation. The fire extinguishing system comprises a water storage tank, a pipeline, a fire pump, a foam liquid storagetank, a foam liquid pump, a proportional mixing device and spray guns. An inlet of the pipeline is connected with the water storage tank. The fire pump, the proportional mixing device and the at leasttwo spray guns are sequentially arranged in the direction from the inlet of the pipeline to an outlet of the pipeline. The proportional mixing device is provided with a first inlet, a second inlet and an outlet and the first inlet and the outlet communicate with the pipeline. An outlet of the foam liquid storage tank is connected with the second inlet of the proportional mixing device through thefoam liquid pump. Supporting columns are arranged at the diagonal positions of the periphery of a transformer in the outdoor transformer substation correspondingly. Each spray gun is arranged at thetop end of the corresponding supporting column. The two spray guns at the diagonal positions can completely wrap the transformer. The wind resistance of a fire extinguishing device of the outdoor transformer is greatly improved through the four-corner arrangement manner, and the all-weather and high-reliability fire fighting requirements can be well met.

Description

technical field [0001] The invention relates to a fire extinguishing system, in particular to a fire extinguishing system for an outdoor substation. Background technique [0002] At present, the fire extinguishing devices of outdoor substations mainly include water spray, foam spray, jet fan fog cannon, etc. Both water spray and foam spray are arranged with many pipe networks and nozzles around the transformer. The construction is complicated, which affects the simplicity and beauty of the surrounding transformer and subsequent maintenance. The jet fan fog cannon has high equipment cost. While spraying water mist or foam mist to cover the transformer, oxygen is continuously supplied to the surroundings of the fire source, and the fire extinguishing effect is at risk. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a fire extinguishing system with simple pipeline layout, strong wind resistance, and all-weather reliable...

[0002] At present, outdoor substation fire extinguishing devices mainly include water spray, foam spray, jet fan fog cannon, etc. Both water spray and foam spray are arranged with many pipe networks and nozzles around the transformer. The construction is complicated, which affects the simplicity and beauty of the surrounding transformer and subsequent maintenance.

The jet fan fog cannon has high equipment cost. While spraying water mist or foam mist to cover the transformer, oxygen is continuously supplied to the surroundings of the fire source, and the fire extinguishing effect is at risk.
