[0048] Working principle: please refer to Figures 1-11 , the electrical equipment can be installed inside the box 1 through the plurality of mounting frames 10, and then the electrical equipment and the current sensor 50 are connected through wires, when the electrical equipment occurs short circuit phenomenon, the current sensor 50 will feed back the electrical signal to the short-circuit grounding indicator 9, at this time the short-circuit grounding indicator 9 will process the electrical signal and feed back to the PLC controller 8, and then the PLC controller 8 knows the position of the short-circuit electrical equipment, when the staff opens the PLC controller 8 to repair the electrical equipment, the staff can accurately know the position of the faulty equipment through the PLC controller 8, at this time the PLC controller 8 controls the micro air pressure pump 14 to start the first pneumatic push rod 21, and then the extension of the telescopic rod of the first pneumatic push rod 21 will drive the mounting frame 10 and the electrical equipment to move, and then the staff can repair the electrical equipment alone, and since the faulty electrical equipment is moved and separated from other electrical equipment inside the box 1, the repair work of the staff will not be disturbed by other electrical equipment;

[0049] When the electrical equipment inside the box 1 is on fire due to aging, the flame sensor 33 will observe the electrical equipment on fire, and then the flame sensor 33 will feed back the electrical signal to the PLC controller 8, and then the PLC controller 8 controls the start of the micro air pressure pump 14, at this time the telescopic rod of the second pneumatic push rod 23 and the first pneumatic push rod 21 will move, and then the telescopic rod of the second pneumatic push rod 23 will retract to drive the corresponding pressure frame 22 to slide down, and then the bottom of the pressure frame 22 will press on the wire connection of the electrical equipment, and at the same time the telescopic rod of the first pneumatic push rod 21 will extend to move the mounting frame 10 and the electrical equipment on fire out of the electrical equipment group, at this time since the connecting wire of the electrical equipment is limited and fixed by the pressure frame 22, the wire of the electrical equipment will be separated from it during the movement, thereby the electrical equipment is powered off;

[0050] At this time, the electrical equipment moved by the first pneumatic push rod 21 will enter the inside of the upper cover 41 and the lower cover 42, and then when the electrical equipment contacts the pressure sensor 46, the pressure sensor 46 will feed back the electrical signal to the PLC controller 8, and then the PLC controller 8 controls the first electromagnet 39 corresponding to the position of the pressure sensor 46 to be powered off, at this time the upper cover 41 attracted by the first electromagnet 39 releases its attraction limiting effect, and then under the elastic tension of the tension spring 43, the upper cover 41 will close to the side of the lower cover 42, and the electrical equipment on fire will be wrapped in the inside of the upper cover 41 and the lower cover 42, and then the PLC controller 8 powers off the corresponding second electromagnet 40, at this time the upper cover 41 and the lower cover 42 can be separated from the side of the mounting plate 38, so as to achieve the effect of facilitating the short-circuit real-time monitoring of the electrical equipment inside the box 1, and facilitating the disengagement and protection isolation operation of the electrical equipment when the electrical equipment is on fire due to aging, thereby avoiding the loss of other electrical equipment inside the box 1 caused by the aging electrical equipment on fire.

[0051] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
