Problems solved by technology
However, the operation of electric heat tracing itself is also easy to cause thermal runaway, and because when electric heat is traced, the heating wire will cause local surface high temperature, which will cause the aging of insulation materials and adhesives and release some gases, which is not only possible Trigger false alarms, affect the normal progress of battery testing, and may also damage other components of battery testing equipment, such as gas detectors used to detect gas components in closed environments
Therefore, the existing electric heat tracing scheme not only has the risk of fire caused by thermal runaway, but also is inconvenient to use and maintain, and the cost of installation and use is high

The invention relates to a fire extinguishing device and battery testing equipment. The fire extinguishing device comprises a spraying assembly, the spraying assembly comprises at least one spraying head arranged in the battery testing environment and a pipeline communicated with spraying head fluid, and when the spraying assembly is started, high-pressure first liquid flows through the pipeline and forms high-pressure liquid mist sprayed into the battery testing environment through the spraying head; the heat supply assembly comprises a heat supply pipeline, the heat supply pipeline is positioned on the outer surface of at least one part of the pipeline, when the heat supply assembly is started, heated second liquid flows through the heat supply pipeline to heat the pipeline and the spray head, and the heat preservation accessory wraps the spray head, the pipeline and the heat supply pipeline in a mode of being thermally isolated from the battery testing environment; and the controller is configured to control the spraying assembly and the heat supply assembly to be opened and closed. According to the fire extinguishing device and the battery testing equipment, the fire extinguishing function can be safely and reliably guaranteed under the extremely low-temperature testing condition.
Description
technical field [0001] The present application relates to the technical field of extinguishing fires that occur during battery testing, and more particularly, the present application relates to fire extinguishing devices and battery testing equipment. Background technique [0002] At present, the performance of batteries, modules and / or battery packs is usually tested under various test conditions by means of battery testing equipment. Due to the existence of relatively extreme test conditions, the tested batteries, modules and / or battery packs are easy to Thermal runaway can lead to fire, so it is necessary to extinguish the fire in a closed environment containing thermal runaway cells, modules and / or battery packs in time during battery testing to protect battery testing equipment. [0003] For example, high-pressure fine water mist can be sprayed by means of a high-pressure fine water mist nozzle to realize fire extinguishing. However, since in practice, the high-pressur...
