Dustproof generator neutral point grounding resistor cabinet

Abstract

The utility model discloses a dustproof generator neutral point grounding resistor cabinet, which comprises a resistor cabinet main body, a rainproof top cover is arranged at the top end of the resistor cabinet main body, a heat dissipation groove is arranged at a position, close to the bottom, of one side in the resistor cabinet main body, and cabinet doors are arranged on two sides of the front end of the resistor cabinet main body. The dustproof assembly is arranged on the outer side of the heat dissipation groove in the bottom of one side of the resistor cabinet main body, and when the resistor cabinet runs, the wind force blown outwards by the heat dissipation fan blows up the dustproof sheet connected with the rotating shaft, so that the normal work of the heat dissipation function is not influenced when the resistor cabinet runs; after the resistor cabinet stops running, when the cooling fan stops rotating, the dustproof sheets fall to block the cooling grooves under the influence of gravity, and meanwhile, the dustproof sheets are more tightly attached to the side face of the resistor cabinet main body through rubber pads, so that dust is effectively prevented from entering the resistor cabinet through the cooling grooves; therefore, the purpose of performing dustproof protection on the resistor cabinet under the condition that the normal heat dissipation function operation of the resistor cabinet is not influenced is achieved.

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a dustproof generator neutral point grounding resistance cabinet. Background Art

[0002] The generator neutral point grounding resistor cabinet is a grounding protection device for the neutral point of the generator. During operation, it maintains the voltage between the neutral point and the ground within a safe range through resistance to avoid accidents caused by excessively high or low voltage. It is an important electrical equipment to ensure the safe operation of the generator.

A new type of dustproof generator neutral point grounding resistor cabinet includes a resistor cabinet body, a device box is fixedly connected to the top of the resistor cabinet body, a mounting slot is provided on the top of the device box, and a fan is provided on the top of the mounting slot. The dustproof generator neutral point grounding resistor cabinet cooperates with each other through the heat dissipation port, the dustproof net and the shell. By providing the heat dissipation port arranged obliquely on the shell, the dust entering the shell with the air is reduced to a certain extent. Combined with the dustproof net in the fixed frame, the dust entering the inside of the resistor cabinet is greatly reduced, thereby reducing the dust accumulation on the related electronic equipment, slowing down the aging speed of the electronic components, and facilitating the resistor cabinet to work better. At the same time, the dustproof net is respectively engaged with the upper card slot and the lower card slot, which is convenient for disassembly and cleaning, and improves the cleaning efficiency of the user. However, during the application of this technical solution, a dust-proof net is provided at the heat dissipation position to make the resistor cabinet dust-proof. The provision of the dust-proof net is likely to affect the normal heat dissipation function, thereby affecting the safe operation of the resistor cabinet. There is a technical problem that the dust-proof performance of the resistor cabinet cannot be effectively improved while ensuring the normal operation of the heat dissipation function of the resistor cabinet.

[0020] Example

[0021] Please refer to Figure 1-4As shown, the utility model provides a dustproof generator neutral point grounding resistor cabinet, comprising a resistor cabinet body 1, a rainproof top cover 5 is arranged on the top of the resistor cabinet body 1, a heat dissipation slot 8 is arranged at a position near the bottom of one side of the inside of the resistor cabinet body 1, the heat dissipation slots 8 are arranged at equal intervals at a position near the bottom of one side of the inside of the resistor cabinet body 1, the heat dissipation slots 8 are arranged horizontally on the inside of the resistor cabinet body 1, cabinet doors 2 are arranged on both sides of the front end of the resistor cabinet body 1, a fixing frame 12 is arranged at the bottom end of one side of the inside of the resistor cabinet body 1, and a heat dissipation fan 13 is arranged on one side of the fixing frame 12, and the heat generated during the operation of the resistor cabinet is discharged through the heat dissipation slot 8 by the heat dissipation fan 13;

[0022] As a further implementation of this embodiment, Figure 1-4 As shown, a connection frame 6 is provided near the bottom of one side of the resistor cabinet body 1, a rotating shaft 11 is provided on one side between the two ends inside the connection frame 6, and the rotating shafts 11 are arranged at equal intervals on one side between the two ends inside the connection frame 6, and a dustproof sheet 7 is provided at the bottom end of the rotating shaft 11. When the heat dissipation fan 13 is started to perform heat dissipation work, the dustproof sheet 7 connected to the rotating shaft 11 is blown up by the wind force blowing outward, so as not to affect the normal operation of the heat dissipation function of the resistor cabinet during operation. The dustproof sheet 7 is arranged on the outside of the heat dissipation groove 8 and corresponds to one of them. When the heat dissipation fan 13 stops rotating after the resistor cabinet stops running, the dustproof sheet 7 falls under the influence of gravity to block the heat dissipation groove 8, thereby preventing dust from entering the resistor cabinet through the heat dissipation groove 8. A rubber pad 10 is provided on the inner side of the dustproof sheet 7, and the rubber pad 10 makes the dustproof sheet 7 fit more closely with the side of the resistor cabinet body 1 after falling, thereby achieving the purpose of dustproof protection for the resistor cabinet without affecting the normal operation of the heat dissipation function, and the feasibility is strong.

[0023] When the resistor cabinet is running, the wind force blown outward by the cooling fan 13 blows up the dustproof sheet 7 connected to the rotating shaft 11, so as not to affect the normal operation of the heat dissipation function of the resistor cabinet. When the resistor cabinet stops running and the cooling fan 13 stops rotating, the dustproof sheet 7 falls down due to gravity to block the heat dissipation slot 8 to prevent external dust from entering the resistor cabinet through the heat dissipation slot 8. At the same time, the rubber pad 10 makes the dustproof sheet 7 fit more closely to the side of the resistor cabinet body 1.

[0024] As a further implementation of this embodiment, Figure 1 and Figure 2As shown, a moisture-proof component is provided at the bottom of the resistor cabinet body 1, and the moisture-proof component includes an overhead mounting seat 4, which is arranged on both sides of the bottom of the resistor cabinet body 1, and the vertical section of the overhead mounting seat 4 is "U"-shaped, and the overhead mounting seat 4 is symmetrically arranged at the bottom of the resistor cabinet body 1. The resistor cabinet body 1 can be mounted on the ground through the overhead mounting seat 4, so that its bottom is a certain distance from the ground to avoid direct contact between the resistor cabinet and the ground. An installation frame 3 is provided between the overhead mounting seats 4 at the bottom of the resistor cabinet body 1, and a moisture-proof pad 9 is provided between the inner side walls of the installation frame 3. The moisture-proof pad 9 can effectively prevent ground moisture from invading the interior of the resistor cabinet, causing internal components and circuits to be damaged by moisture and aging, thereby improving the moisture-proof performance of the resistor cabinet and further ensuring the safe operation of the resistor cabinet.

[0025] When in use, the overhead mounting seat 4 is arranged on both sides of the bottom of the resistor cabinet body 1. The resistor cabinet body 1 can be mounted on the ground through the overhead mounting seat 4, so that its bottom is a certain distance from the ground, and the moisture-proof pad 9 is installed on the bottom of the resistor cabinet body 1 through the mounting frame 3, so as to prevent the ground moisture from invading into the interior of the resistor cabinet and causing the internal components and circuits to be damaged by moisture and aging;

[0026] Specific working principle:

[0027] When using the neutral point reading resistor cabinet, first, when installing the resistor cabinet, the resistor cabinet body 1 can be installed on the ground through the overhead mounting seat 4, so that its bottom is a certain distance from the ground, and the moisture-proof pad 9 is installed on the bottom of the resistor cabinet body 1 through the mounting frame 3. When the resistor cabinet is running, the heat generated in the resistor cabinet during operation is discharged through the heat dissipation groove 8 by the heat dissipation fan 13, and the heat dissipation wind blows up the dust-proof sheet 7, so as not to affect the normal operation of the heat dissipation function of the resistor cabinet. After the resistor cabinet stops running, when the heat dissipation fan 13 stops rotating, the dust-proof sheet 7 falls due to gravity and blocks the heat dissipation groove 8. At the same time, the rubber pad 10 makes the dust-proof sheet 7 fit more closely with the side of the resistor cabinet body 1, so as to prevent external dust from entering the resistor cabinet through the heat dissipation groove 8. The elevated design and the moisture-proof pad 9 can prevent ground moisture from invading the inside of the resistor cabinet, causing internal components and circuits to be damaged by moisture and aging. At the same time, the rainproof top cover 5 is used to protect the resistor cabinet from rain from the top to ensure the safe operation of the resistor cabinet.
