Embodiment Construction

[0024] In order to determine the risk of fire extinguishing the energy storage system with water, the inventor of the present invention first inquired and studied the conditions of human body electric shock and the parameters of protective protective gear.

[0025] According to the existing reference literature, the lowest resistance of the human body resistance model is 500 ohms, and the acceptable direct current is 50mA. The voltage of the lithium battery energy storage system is usually below 1000V. Under abnormal conditions, the AC part will be automatically turned off, leaving only Direct current part. Therefore, as long as the resistance of the water column and the resistance of the waterproof appliance are sufficient, the human body can be prevented from getting an electric shock, thereby avoiding the risk of electric shock.

[0026] According to actual measurement, the typical values ​​of relevant parameters are as follows: 1) Protective protective gear resistance: In the c...

Abstract

The invention discloses a fire extinguishing plant of an energy storage system, comprising a sprinkler device, a smoke drying device, a water retaining device, and a water drainage device, wherein, the sprinkler device is used for spraying running water at the ablaze battery module, the smoke drying device is used for discharging smoke on the fire point and drying the battery module when water spraying stops, and the water retaining device is arranged opposite to the sprinkler device for blocking the water sprayed from the sprinkler device to prevent the water from flowing around any region outside the ablaze battery module and allowing the water to enter the water drainage device to discharge. According to the invention, water is used for fire extinguishment and simultaneously smoke discharge is carried out, thus the speed of fire extinguishment is fast, the smoke is little, inflammable gases released from the battery can be rapidly removed by timely smoke discharge in the fire extinguishing process, the danger of gas suffocation is avoided, the explosion risk caused by accumulation of inflammable gases injected by the battery in the process of using gas for fire extinguishment is avoided, and the electric shock caused by chaotic water flow is effectively avoided by the water retaining device and the water drainage device.

Description

Technical field [0001] The invention relates to the field of fire protection of energy storage systems, and more specifically, to a fire extinguishing device for energy storage systems with high reliability. Background technique [0002] At present, grid energy storage systems, small energy storage systems in buildings, UPS (Uninterruptible Power System, uninterruptible power supply) energy storage systems, etc. are all composed of lithium battery packs. Existing lithium batteries will continue to release combustible gas for a period of time under abnormal conditions, such as a 50AH single lithium battery made of lithium iron phosphate. In the event of thermal runaway or abnormal short circuit, the volume can expand up to 50%. %, the thickness can increase by 50%~70% at most. After the internal pressure reaches the safety threshold of 0.4~0.6MPa, the gas will break through the safety valve and maintain the release jet for about 20 minutes. The jetted gas is mainly composed of met...
