Sand spraying firefighting device for transformer substation

Abstract

The invention provides a sand spraying firefighting device for a transformer substation, which can implement automatic control and improve the diversity of firefighting monitoring and automatic fire-extinguishing functions of the transformer substation so as to reach effective prevention and extinguishing effects. The sand spraying firefighting device comprises a control system, an unmanned aerialvehicle, a fire-extinguishing unit, a firefighting sand recycling device and transformer substation equipment, wherein the control system is used for controlling flight action of the unmanned aerialvehicle and is used for investigating fire behaviors; after an investigating signal of the unmanned aerial vehicle is analyzed and calculated, a corresponding control signal is sent out according to apre-set program to a firefighting unit; the unmanned aerial vehicle is used for receiving instruction action and an investigating direction of the control system and transmitting investigating data to the control system; the firefighting unit is used for receiving a control signal of the control system and carrying out firefighting action; the firefighting sand recycling device is used for recycling, circulating and reutilizing firefighting sand which is used by the transformer substation equipment and the periphery. By adopting the sand spraying firefighting device provided by the invention,a pipeline maintenance problem of a common foam or water spraying device is solved and equipment damage accidents which are possibly caused by false operation of oil discharging and nitrogen injection are avoided, so that effective prevention and extinguishing effects are realized.

Description

technical field [0001] The invention relates to the field of substation fire safety, in particular to a sandblasting fire-fighting device for a substation. Background technique [0002] Most of the transformers, voltage transformers, and current transformers of the primary equipment in the substation adopt oil-immersed insulation, and the amount of mineral insulating oil is relatively large. It even reaches about 130t, and the single-phase oil weight of the high voltage reactor reaches about 70t. The insulating oil used has a flash point of 135-150°C, an ignition point of 165-195°C, and a spontaneous ignition point of about 332°C. It is easy to evaporate and burn, and can form an explosive mixture when mixed with air. The battery in the substation operates in parallel with the charger as a standby state, and all protection devices, automation devices, emergency lighting and other equipment rely on DC to provide power, and the consumption is relatively large. The substation...
