Embodiment 1

[0071] Such as image 3 As shown, taking the 110kV indoor substation as an example, the distribution and working process of each device in this embodiment are as follows:

[0072] Cable trench: In order to prevent the dissipation of the gas fire extinguishing system from weakening the fire extinguishing effect, and to effectively disperse the dry powder in the trench, and to ensure that there is basically no negative impact of misoperation, choose the first temperature-sensing cable, the first point-type temperature-sensing detector, The first point smoke detector and the first suspended dry powder fire extinguisher are combined, and both are arranged in the cable trench;

[0073] Working process: the temperature signal collected by the first temperature-sensing cable is output to the fire alarm control device; the fire alarm control device judges the temperature signal from the first temperature-sensing cable, and when the temperature value exceeds the set value, the fire ala...

Embodiment 2

[0097] Such as Figure 4 As shown, since in most substations, the transformers are located outdoors, especially in the new UHV substations, the main transformer is too large, so it is generally set as two transformers + adjusting and repairing transformers; although at present, with the shortage of urban land, urban Newly built substations of 220kV level and below gradually adopt indoor forms, and even some 500kV substations also adopt indoor forms, but transformers and GIS are only a small number of indoors overall; Work, for the situation of outdoor transformer and outdoor GIS, on the basis of embodiment one, arrange the second row of oil nitrogen injection device and the seventh gas storage type full submersion dry powder fire extinguishing device in the outdoor transformer, and the tenth video device, the first Seventh, the gas storage type dry powder fire extinguishing device is connected to the oil temperature gauge, coil winding temperature gauge and circuit breaker tha...

Abstract

The invention discloses a sub-regional protection type substation fire fighting monitoring and early-warning and fire fighting system which comprises a video unit, a detection device, a fire alarm control device and a fire fighting device, wherein the detection device comprises a temperature sensing cable, a characteristic gas detection device, a linear infrared beam smoke and temperature sensing detector, a point type temperature sensing detector and a point type smoke sensing detector; the fire alarm control device gathers signals collected by the detection device and sends a starting signal to the fire fighting device; the fire fighting device comprises a fire trace tube fire fighting device, a gas storage type total-flooding dry powder extinguishing device, a suspension type dry powder fire extinguisher, an oil-drainage nitrogen-filling device and a water mist fire extinguishing device. According to equipment in each sub region and the combustion characteristic of combustibles of the sub region, the sub-regional protection type substation fire fighting monitoring and early-warning and fire fighting system selects corresponding detection devices and corresponding fire fighting devices for combined distribution, carries out targeted fire detection, early warning and fire fighting arrangement, and comprehensively improves the prevention and fire fighting capability of substations to fire.

Description

technical field [0001] The invention relates to life-saving and fire-fighting in classification table A62, in particular to fire-fighting monitoring and early warning in substations. Background technique [0002] The substation is the assembly point of power transmission and distribution in the power system, which plays the role of transforming voltage, receiving and distributing power, controlling power flow and adjusting voltage. There are a lot of combustibles in the equipment in the substation, such as insulating oil and insulating cardboard in transformers (reactors, capacitors), outer insulating sheaths of power cables, and various components in electrical cabinets. As the core primary equipment, transformers mostly use oil-immersed natural cooling, so the oil consumption is huge and the fire hazard is extremely high; the outer sheath of power cables is the biggest fire hazard point, due to the high density of cables laid in the substation , operation and maintenance ...
