Embodiment Construction

[0027] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0028] A fire-fighting method for a prefabricated cabin type lithium iron phosphate battery energy storage power station, comprising the following steps:

[0029] Step 1: Position determination: mark the position of the energy storage battery in the prefabricated cabin according to the planning of the module, fix the position of each battery module in the prefabricated cabin, fix the position of the fire extinguishing agent nozzle, and mark the position;

[0030] Step 2: Infrared distance measurement: place the infrared distance meter at the center point of the prefabricated cabin, and record the highest point D of each battery in each battery module 1 , the lowest point D 2 , the infrared rangefinder conducts a test of the highest point an...

Abstract

The invention relates to a fire-fighting method and system for a prefabricated cabin type lithium iron phosphate battery energy storage power station. The method comprises the steps of marking the positions of energy storage batteries in a prefabricated cabin according to the planning of a module; placing an infrared distance meter at the central point position of the prefabricated cabin, and testing the highest point and the lowest point of each battery once in 30s by the infrared distance meter; using an infrared thermometer for measuring the temperature of a battery module, and using a control platform for analyzing the measured temperature; performing infrared gas testing on the battery module by adopting an infrared gas detector; and if H2 and CO are detected, cutting the battery module is cut off through the control platform. Whether the corresponding battery module is in the thermal runaway critical state or the thermal runaway state is judged through each control platform, the specific battery module with thermal runaway can be accurately judged, so that the corresponding fire extinguishing agent spray head is controlled to spray the fire extinguishing agent to extinguish fire, the situation that normal battery clusters are influenced by large-scale spraying of the fire extinguishing agent is avoided, and resources are effectively saved.

Description

technical field [0001] The invention belongs to the field of fire protection of energy storage power stations, and relates to a prefabricated cabin type lithium iron phosphate battery energy storage power station, in particular to a fire fighting method and system for a prefabricated cabin type lithium iron phosphate battery energy storage power station. Background technique [0002] One of the two major factors restricting the development of lithium iron phosphate batteries is safety. Accidents of combustion and explosion of electrochemical energy storage power stations often occur. Therefore, it is necessary to rapidly improve flame retardant, fire extinguishing and explosion-proof technologies. [0003] At present, for the prefabricated cabin of the lithium iron phosphate battery energy storage power station, temperature detectors, smoke detectors, etc. are usually used to detect the fire. When a fire is detected, the fire extinguishing equipment in the cabin is turned on...
