Scope of application
Double-layer explosion-proof test chamber is used to test the heat resistance, cold resistance, dry resistance and explosion-proof protection of various batteries. Suitable for batteries, electronics, electrical appliances, communications, instruments, vehicles, rubber and plastic products, metal materials, food, medicine, chemical building materials, aerospace, ships, weapons, colleges and universities, and scientific research units.
Characteristics of double-layer explosion-proof test
High temperature resistant smoke sensor
1. When the battery explodes, smoke in the cabin is sensed and the protection system is activated.
2. The equipment is shut down, the protection device of the independent power supply is turned on, and the fire extinguishing device is turned on. The fire extinguishing device delays the opening of the smoke exhaust fan.
pressure relief system
1. When the battery explodes, the pressure difference between inside and outside the cabin is large. When the pressure reaches 3~8KPA, the pressure relief system will activate.
Exhaust system
1. After turning on the fire extinguishing system or air dilution system, delay turning on the smoke exhaust system to discharge the gas in the cabin.
2. After the test is completed, the exhaust is exhausted and the door is allowed to open.
fire extinguishing system
1. Optional automatic sprinkler/thousand ice/heptafluoropropane/aerosol fire extinguishing device
Infrared temperature measurement device
1. Infrared temperature measurement and smoke sensor combination solution, the typical alarm action time of battery thermal runaway is as follows. When the battery thermal runaway is within the viewing angle of the infrared sensor, accurate alarm linkage can be performed within 2 seconds after the thermal runaway occurs.
