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)

Abstract

The invention relates to a device and a method for power management of explosion-proof electrical equipment. The device comprises a power supply and a plurality of electric equipment groups located in a plurality of electric branches, a plurality of electronic switches which are positioned in each electric branch and are connected with a power supply and electric equipment, a current sensor which is positioned between the electronic switch and the electric equipment group and is used for detecting the current of each electric branch, a signal conditioner which is connected with the plurality of electric equipment groups, and is used for adjusting the signals of the current sensor to a range capable of being processed by the CPU and adjusting the control signals to a level at which the electronic switch can be turned on and turned off, and a communication circuit, a clock circuit and a memory which are respectively connected with the CPU. According to the device and the method disclosed by the invention, the current of each electric branch is monitored, and overcurrent protection is realized according to set parameters; load current of each electric branch is monitored and recorded, and the load current is sent to the control host to provide useful data for fault analysis and load balance; and the fault reset and on-off control functions of each electric branch can be realized under the condition that the door cover of the explosion-proof shell is not opened.

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...
