Description

TECHNICAL FIELD

[0001] The utility model relates to a power cabinet technical field, concretely is a dustproof structure of power cabinet. BACKGROUND

[0002] The switch cabinet plays the roles of switch, control and protection in the power generation, power transmission and distribution and electric energy conversion of the power system, especially in the transformer, and a switch cabinet with a transformer is installed on one side of the high-voltage bus of the transformer substation, which can reduce the high-voltage electric power of 10kV to low-voltage electric power of 380V to provide power supply for 220V and 380V to be used in the transformer substation. In the process of voltage conversion, a large amount of heat is generated, so the switch cabinet generally needs to be perforated for heat dissipation. After the heat dissipation holes are set, the external dust will enter the interior of the switch cabinet from the heat dissipation holes, which will affect the performance of the electrical components in the equipment.

[0003] The current power cabinet usually adopts heat dissipation grids or heat dissipation covers for natural heat dissipation. If the power cabinet is used in an environment with a lot of dust, the external dust will inevitably enter the power cabinet through the heat dissipation grids or heat dissipation covers and cover the electrical components, which will affect the heat dissipation of the electrical components and even cause damage. Although a filter cloth is installed at the heat dissipation grids or heat dissipation covers to filter the dust entering the power cabinet, the filter cloth needs to be cleaned or replaced after a long time of use. Since the current heat dissipation grids or ventilation covers are usually fixed by a plurality of bolts, it is time-consuming and laborious to disassemble them, which brings inconvenience to the workers.

[0028] In detail, the two inner side walls of the mounting port 3 are respectively provided with a first mounting groove 6 along the vertical direction, the two sides inside the mounting frame 4 are respectively fixed with a mounting rod 7, and the mounting rod 7 can slide up and down in the inside of the first mounting groove 6.

[0029] In more detail: one side of the installation frame 4 is installed with a first locking assembly 8 in the vertical direction, one side of the installation rod 7 is installed with a second locking assembly 9 in the vertical direction, through the cooperation of the first locking assembly 8 and the second locking assembly 9, the installation frame 4 can be quickly disassembled; so as to provide convenience for the staff.

[0030] The first locking assembly 8 is explained in detail: the first locking assembly 8 includes a first protrusion 801 fixed on the inner wall of the first installation slot 6 in the length direction, and a first gap is left between adjacent first protrusions 801;

[0031] The second locking assembly 9 is explained in detail: the second locking assembly 9 includes a second protrusion 901 fixed on the side of the installation rod 7 in the length direction, and a second gap is left between adjacent second protrusions 901;

[0032] It should be noted that: the length of the first protrusion 801 is less than the length of the second gap; the length of the second protrusion 901 is less than the length of the first gap; so that the second protrusion 901 can extend through the first gap to the inside of the first installation slot 6;

[0033] If the installation frame 4 is installed: first, the second protrusion 901 is compared with the first gap respectively; then push the installation frame 4, the installation frame 4 can drive several second protrusions 901 to move horizontally through the installation rod 7, so that the second protrusion 901 extends through the first gap to the inside of the first installation slot 6; then loosen the installation frame 4, and drop down under the action of its own gravity; if the second protrusion 901 and the second protrusion 901 are compared with each other, the installation frame 4 is locked, preventing the installation frame 4 from falling off the cabinet 1;

[0034] If the installation frame 4 is disassembled: push the installation frame 4 upwards, so that the installation frame 4 drives several second protrusions 901 to move upwards through the installation rod 7, if the second protrusion 901 is misaligned with the first protrusion 801, pull the installation frame 4 outward, so that the installation frame 4 can be taken out from above the cabinet 1.

[0035] The bottom of the installation frame 4 is fixed with an installation protrusion 12, and the installation protrusion 12 is provided with a locking piece 13, and the side of the cabinet 1 is provided with a locking hole 14 matched with the locking piece 13; through the cooperation of the locking piece 13 and the locking hole, the installation frame 4 is fastened, preventing the installation frame 4 from loosening during use.

[0037] It should be noted that when the locking member 13 is a locking bolt threaded on the mounting protrusion 12, the locking hole 14 is a threaded hole, and the locking bolt is threaded through the mounting protrusion 12 and the threaded hole to be connected, thereby playing a fastening role.

[0038] The opposite side of the two mounting rods 7 is provided with a second mounting groove 701 along the length direction, and the same filter assembly 10 is slidingly installed between the two second mounting grooves 701. Through the arrangement of the filter assembly 10, when the dust from the outside enters the inside of the cabinet 1, the filter assembly 10 can filter the dust entering the cabinet 1, preventing dust from entering the inside of the cabinet 1. It should be noted that a plurality of support plates 11 are vertically fixed inside the lower part of the mounting frame 4. Through the arrangement of the support plates 11, the filter assembly 10 is supported to prevent the filter assembly 10 from falling downward due to its own gravity.

[0039] In detail: the filter assembly 10 includes a support frame 1001. Under normal circumstances, the two sides of the support frame 1001 can be connected to slide up and down inside the second mounting groove 701. The support frame 1001 is provided with a filter cloth 1002. Through the arrangement of the filter cloth 1002, the dust in the air is filtered.

[0040] When the filter cloth 1002 needs to be cleaned or replaced after a long time, first, the locking member 13 can be loosened so that the locking part of the locking member 13 is separated from the inside of the locking hole 14.
