Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a combined high- and low-voltage switch cabinet with a dustproof function. Background Art

[0002] High-voltage switchgear refers to electrical products used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. The working voltage level of high-voltage switchgear is 3.6kV~550kV. It includes high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and disconnecting devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear.

[0003] Dust is easily accumulated at the air inlets and outlets on the existing cabinets for heat dissipation. The dust will also enter the cabinet through the air inlets and outlets and adhere to the electrical components in the cabinet, which will affect the use of the components for a long time. Moreover, the internal space of the cabinet is large, and it is inconvenient to control the specific position of some small switch devices during installation, which brings trouble to work.

[0004] In the patent document with publication number CN219980118U3, a high-voltage switch cabinet with dustproof function is disclosed. The baffle is driven by an electric push rod to move closer to the side wall of the cabinet so that the baffle seals the exhaust port to prevent dust from entering the cabinet from the exhaust port and adhering to the electrical components in the cabinet, which will affect the use of the components for a long time.

[0005] However, when the high-voltage switch cabinet with dustproof function is in use, it is not flexible enough to install some equipment inside the switch cabinet, and the exhaust port is closed by a baffle to prevent dust during use. The baffle will always seal it, and it is difficult to prevent dust from entering the cabinet when it is removed. Therefore, it is necessary to propose a combined high and low voltage switch cabinet with dustproof function. Utility Model Content

[0026] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A combined high and low voltage switch cabinet with dustproof function, comprising a switch cabinet body 1, a dustproof box 2 fixedly connected to one side of the switch cabinet body 1, and a support frame 3 fixedly connected to the inside of the switch cabinet body 1, a dustproof mechanism is arranged inside the dustproof box 2, and a fixing mechanism is arranged on one side of the support frame 3;

[0029] The dustproof mechanism includes a filter plate 201, a mounting frame 202, a dust shield plate 203, a baffle 204, a limiting hole 205, a mounting column 206, a limiting block 207, a limiting rod 208, a reset spring 209 and a fixing block 210. The mounting frame 202 is arranged inside the dustproof box 2, the baffle 204 is fixedly connected to one side of the mounting frame 202, the filter plate 201 is slidably connected to one side of the mounting frame 202, the dust shield plate 203 is fixedly connected to the inside of the mounting frame 202, and the dust shield plate 203 is arranged in a downwardly inclined state inside the mounting frame 202 to prevent dust from directly entering.

[0035] Working principle:

[0036] First, through the set fixing mechanism, some small devices in the switch cabinet (for example: circuit breakers, disconnectors and load switches, etc.) can be installed on the mounting block 306. By loosening the limit threaded rod 305, the entire cross plate 304 can be moved to control the position of these devices inside the switch cabinet body 1 after installation. After adjustment, the limit threaded rod 305 can be tightened to fix it.

[0037] Furthermore, through the dustproof mechanism, dustproof boxes 2 are provided on both sides of the switch cabinet 1. The dust in the air will first be blocked by the oblique dust shield 203 arranged inside the installation frame 202, and then filtered by the filter plate 201 on one side of the installation frame 202 to prevent the dust in the air from entering the interior of the switch cabinet 1.

[0038] Furthermore, when the filter plate 201 needs to be replaced, the limit block 207 can be pulled open to compress the return spring 209. At this time, one side of the limit rod 208 is pulled open from the inside of the limit hole 205. At this time, the limit on the installation frame 202 is released, and then the installation frame 202 can be taken out from the inside of the dustproof box 2. Correspondingly, the filter plate 201 is limited by the baffle 204 on one side of the installation frame 202. The filter plate 201 can be directly pulled out from the inside of the installation frame 202 to replace the filter plate 201.

[0039] Furthermore, by means of the heat dissipation mechanism, the hot air inside the switch cabinet 1 can be blown out after the heat dissipation fan 403 is started, thereby achieving the effect of heat dissipation inside the switch cabinet 1 .

[0040] Furthermore, a support frame 3 is provided inside the switch cabinet 1 to divide the internal space of the switch cabinet 1, and the partitions 302 provided on the left and right sides of the support frame 3 divide the internal space of the switch cabinet 1 into four parts.
