Abstract
The utility model relates to an explosion-proof nickel metal hydride power supply control cabinet. A mechanical structure and control circuit combined design is employed according to the actual conditions of coal mine well safety monitoring and network communication power supply. A nickel metal hydride power supply and a charging and discharging management device are disposed in an explosion-proof cabinet body. The nickel metal hydride power supply is charged when the power supply is in a normal state, and the nickel metal hydride power supply is used for supplying power when a failure happens to the power supply through an instantaneous conversion, so that safety monitoring devices and network communication devices are guaranteed to work normally. The explosion-proof nickel metal hydride power supply control cabinet which employs advanced explosion proof design, is rapid in conversion and balanced in charging and discharging. The explosion-proof nickel metal hydride power supply control cabinet is an ideal explosion-proof nickel metal hydride power supply control cabinet.
Description
Technical field
The utility model relates to a kind of explosion-proof type ni-mh power controling box, belongs to the technical field of stand-by power supply Control and Application under coal mine.
