SAQE switch cabinet cable head explosion-proof protection device on-line monitors the temperature of busbar, dynamic and static contact of circuit breaker, cable head connection, etc. in the switch cabinet. Through intelligent analysis of the relationship between current and temperature, the corresponding set operation is carried out according to the deviation degree of current temperature curve. When the heating temperature of each connection exceeds the set value due to fault, the system will send out temperature alarm signal to effectively prevent the switch cabinet Temperature rise fault. At the same time, install the arc light sensor in the cable room. The arc light sensor is facing each connection point to detect the arc light signal. In case of arc light, the fault source can be cut off within 7 ms to minimize the harm of arc light to the equipment.
