[0027] As Figure 1 Shown, in the embodiment, hole group 20 is arranged in multiple groups along the height direction of installation plate.The structure can install circuit breaker in different positions, so that multiple circuit breakers 13 can be installed on installation plate.A vertical hole group 20 is arranged symmetrically on both sides of busbar on installation plate.A vertical hole group 20 is further arranged outside the vertical hole group on one side, so that larger circuit breakers can be installed on the hole group 20 outside.

[0028] Combined Figure 4 And Figure 5As shown, in this embodiment, an inner door 30 is installed in the cabinet 10 in front of the mounting plate 11. A window 31 is provided on the inner door 30 for facilitating the operation of the circuit breaker 13. A frame 32 extending inwardly is connected to the periphery of the window 31. A bus bar cover 34 is provided in the window 31 to cover the bus bar 33. The bus bar cover 34 has a plurality of heat dissipation holes. The inner door 30 is divided into an upper door body 301 at the upper portion and a lower door body 302 at the lower portion. When the inner door 30 is closed during normal use, it can provide protection to prevent the operator from being injured during maintenance and repair. When repairing, the inner door 30 can be opened for convenience. The window is also convenient for the operator to operate the circuit breaker.

[0029] A ventilation base 102 is also included. The cabinet 10 is installed on the ventilation base 102. The ventilation base 102 is in communication with the interior of the cabinet 10. A pair of outer doors 14 is hingedly connected to the outside of the inner door at the front of the cabinet 10. First ventilation holes 103 are provided on the ventilation base 102 and the lower portion of the outer door 11. Second ventilation holes 104 are provided on the upper door body 301 of the inner door 30 and the upper portion of the outer door 14. Since the bus bar generates heat after a period of operation, the temperature of the air in the cabinet rises. The hot air rises due to its low density and is discharged through the second ventilation holes at the top of the cabinet. Cold air is continuously supplied to the cabinet through the first ventilation holes at the bottom, forming a natural ventilation cycle in the cabinet and achieving the purpose of heat dissipation.

[0030] In combination Figure 5 As shown, side plates 15 are installed on the left and right sides of the cabinet 10. A plurality of mounting holes 151 are formed in each side plate 15 from top to bottom. A mounting plate 16 is detachably installed at each mounting hole 151. Each mounting plate 16 is fixed to the side plate 15 by screws. Since the power distribution cabinet generally adopts a fully enclosed structure, its main purpose is to prevent the intrusion of external dust, moisture and other impurities to ensure the safe and reliable operation of electrical equipment. Therefore, during the manufacturing process of the power distribution cabinet, holes for connecting the power supply of the equipment are not pre-provided. Usually, before the power distribution cabinet is installed in the power distribution room, according to the actual needs, holes with sizes and numbers suitable for the power supply of the equipment are accurately opened on site. Then, the power distribution cabinet is installed in the power distribution room, and the power supply of the equipment is connected to the bus bar in the power distribution cabinet through the circuit breaker. However, when new equipment needs to be added in the subsequent production of the enterprise, there is no hole in the power distribution cabinet for the power supply line of the new equipment to pass through. If the power distribution cabinet is directly opened in the power distribution room to solve this problem, it may cause serious safety hazards. According to the above technical solution, when the power supply line of the new equipment needs to be connected to the power distribution cabinet, the mounting plate at one mounting hole can be removed. Then, the mounting plate 16 is moved outside the power distribution room and a hole suitable for the power supply line of the equipment is opened. Then, the mounting plate with the hole is installed back to the original position. The power supply line of the new equipment is connected to the circuit breaker in the power distribution cabinet through the hole in the mounting plate 16, which is very safe and convenient.

[0031] In combination Figure 6 As shown in the drawings, in the present embodiment, the mounting plate 16 comprises a plate body 161 and a lower edge connected to the lower edge of the plate body 161. The lower edge of the mounting plate 16 is pressed on the upper edge of the adjacent lower mounting plate 16. The lower edge comprises an inclined portion 162 connected to the lower edge of the plate body 161 and a vertical portion 163 connected to the lower edge of the inclined portion 162. A sealing rubber is attached to the inner side of the lower edge. Since the mounting plate is detachably mounted at the mounting opening, there will be a gap between the mounting plate 16 and the side plate 15. When it is humid and cold, because of the temperature difference between the inside and outside of the cabinet, water vapor in the air will attach to the surface of the cabinet to form water droplets. When the water droplets flow down the side plate, they may seep into the cabinet through the gap between the mounting plate 16 and the side plate 15, causing a safety hazard. With the structure of the mounting plate described above, when there are water droplets on the side plate, the water droplets directly drip onto the bottom surface along the plate body and the lower edge, preventing liquid from seeping into the cabinet. In addition, the upper edge of the uppermost mounting plate and the side plate can be sealed with a sealing rubber to prevent water droplets from seeping in between the uppermost mounting plate and the side plate.

[0032] In summary, in the present utility model, the bracket is installed on the back of the circuit breaker, the hook head of the bracket is inserted into the slot, and the bracket is quickly installed in place through the cooperation of the auxiliary hole and the through hole, so that the conductive plug of the circuit breaker is inserted into the busbar, and finally fixed by the locking screw. The structure is simple and convenient to use. An inner door is installed in the cabinet, which can play a protective role during normal use, preventing operators from being injured during maintenance and repair. The window also facilitates the operation of the circuit breaker by the operator. The inner door can also be opened for easy maintenance during maintenance.

[0033] The above describes one embodiment of the present utility model in detail, but the content described is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of the present utility model. Any equivalent changes and improvements within the scope of the present utility model application shall still belong to the patent coverage of the present utility model.
