Accident isolation system for energy storage power station

Abstract

The invention provides an accident isolation system for an energy storage power station. A plurality of energy storage battery prefabricated cabins (1) are placed in the energy storage power station, and each is characterized by comprising an explosion-proof shell (2), an accident handling subsystem (3), a mobile platform (4) and a mobile mechanism (5), wherein the front side of the explosion-proof shell (2) is fixedly connected with the accident disposal subsystem (3), and the rear side of the explosion-proof shell (2) is an open type opening and is provided with a sealing door (201) capable of realizing a sealing function; when an internal out-of-control accident occurs in one of the energy storage battery prefabricated cabins (1), the moving mechanism (5) is started to drive the moving platform (4), the explosion-proof shell (2) above the moving platform (4) and the accident handling subsystem (3) to move to the position near the energy storage battery prefabricated cabin (1) where the accident occurs, and then a translation mechanism (301) is started to contain the energy storage battery prefabricated cabin (1) with the accident in a cavity of the explosion-proof shell (2); and then the sealing door (201) is closed, so that physical isolation of the energy storage battery prefabricated cabin (1) in which the accident occurs is realized.

Description

technical field [0001] The invention relates to the technical field of energy storage power station management, in particular to an accident isolation system for an energy storage power station. Background technique [0002] In existing electrochemical energy storage power stations, batteries need to be used on a large scale. Due to the non-negligible safety problems of the battery itself, in the case of large-scale use, and with deep discharge and charging as the main method of use, the possibility and danger of accidents in energy storage power stations increase; in addition, when energy storage When an accident occurs in a certain module in the power station, if it cannot be dealt with in a timely and reasonable manner, the situation will deteriorate rapidly and affect the overall system to form a chain reaction, resulting in irreparable huge losses and safety risks. [0003] In the prior art, battery-based energy storage power stations usually adopt the design of (conta...

Problems solved by technology

[0004] Although through various technical means, most accidents can be controlled within a single energy storage battery prefabricated cabin, or even within a smaller range; however, it cannot be ruled out that all internal fire protection measures in the energy storage battery prefabricated cabin fail, and then a vicious accident occurs At this time, it is basically impossible to prevent the complete scrapping of the prefabricated cabin of the energy storage battery, but it is still possible and necessary to prevent the further spread of the accident.

For such accidents, although there is a certain amount of time to be able to characterize the accident, but there is no strong fire-fighting means to deal with it.

Usually, it can only be treated by spraying a large amount of water from the outside; and such measures are not only unsatisfactory in effect, poor in safety, but also produce a large amount of toxic and harmful waste gas and waste water, polluting the environment; according to estimates, single container prefabricated The external fire fighting of the cabin will consume at least about 300-500 tons of water
