Method and device for power management of explosion-proof electrical equipment

Abstract

The invention relates to a device and a method for power management of explosion-proof electrical equipment. The device comprises a power management unit, a cloud server, an intelligent gateway and a terminal. The power supply management unit is used for managing a power supply of the explosion-proof electrical equipment; the cloud server is connected with the power management unit and is used for storing and analyzing data and sending a command to the power management unit through a network; the intelligent gateway is used for forwarding the data of the power management unit to the cloud server; and the terminal is used by a user to view or set the data of the power management unit. Therefore, according to the device and the method, the current can be detected, the branch load condition can be monitored, fault reset and on-off control can be carried out on each power supply branch under the condition that the door cover of the explosion-proof shell is not opened, data such as the current and the working state of the device (load) can be collected by utilizing a network technology and a cloud computing technology, and device fault analysis and health diagnosis can be realized.

Description

technical field [0001] The present disclosure relates to explosion-proof electrical equipment, and more particularly to methods and apparatus for power management of explosion-proof electrical equipment. Background technique [0002] For electrical equipment used in explosive environments (such as coal mines containing gas, chemical plants containing flammable and explosive gases, etc.), specific measures must be taken to prevent electric sparks or thermal effects from igniting the surrounding explosive environment. Among various explosion-proof forms (potting type, intrinsically safe type and flameproof type, etc.), the electrical equipment for explosive gas atmospheres protected by the flameproof enclosure "d" (hereinafter referred to as flameproof electrical equipment) is the most used, such as in GB3836 As defined in .2, flameproof enclosure "d" (flameproof enclosure "d") is an explosion-proof form of electrical equipment, the enclosure of which can withstand the interna...

Problems solved by technology

However, this method has two obvious disadvantages. One is that the overcurrent level at that time is unknown after the fuse blows or the circuit breaker trips; Cover --> Troubleshooting --> Replace the fuse; circuit breaker: need to stop the front power supply --> Open the door --> Troubleshooting --> Closing)

Moreover, in the prior art, the collection of data such as load current and load working status, the statistics of equipment faults, the diagnosis of equipment health status, etc. cannot be done automatically without manual work.
