Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a corrosion-resistant high-voltage power distribution cabinet. Background Art

[0002] High-voltage distribution cabinet refers to the switch, control or protection function used in power generation, transmission, distribution, power conversion and consumption of power system; the high-voltage distribution cabinet body, as a functional component of the high-voltage distribution cabinet, also plays a relatively important role.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing corrosion-resistant high-voltage distribution cabinet does not have the function of selectively shielding the vents. During long-term use, the vents are always in a ventilated state, even when no heat dissipation and ventilation are required. Too much moisture enters the cabinet, accelerating the downward speed of internal components. The corrosion protection is not ideal and urgently needs to be improved. Therefore, we propose a corrosion-resistant high-voltage distribution cabinet. Utility Model Content

[0004] The utility model aims to provide a corrosion-resistant high-voltage power distribution cabinet, which solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a corrosion-resistant high-voltage power distribution cabinet, comprising a cabinet body, baffles are placed at the middle of the inner sides of the two side walls of the cabinet body, slide rails are fixedly installed on the tops of the inner walls on both sides of the cabinet body, and inner rods are fixedly installed longitudinally in the slide rails;

[0006] An indicator light is fixedly installed in the middle of the upper surface of the cabinet, a temperature sensor is fixedly installed on one side of the lower surface of the cabinet top wall, a vent is fixedly installed in the middle of the two side walls of the cabinet, and a humidity sensor is fixedly installed on the upper side of the outer wall of the cabinet near the vent;

[0007] A bracket is fixedly installed on the top of the inner side of the baffle, an iron block is fixedly installed on the top of the bracket, and the iron block is located in the slide rail, and a processor is fixedly installed on the front side of a group of the slide rails;

[0008] The inner rod is movable and penetrates the iron block. A tension spring is sleeved on the top of the inner rod, and the two ends of the tension spring are respectively fixedly connected to the iron block and the inner wall of the top of the slide rail. An electromagnet is fixedly installed on the bottom end of the inner rod, and the electromagnet is fixed on the inner wall of the bottom of the slide rail.

[0009] A limit block is placed on the side of the rear inner wall of the slide rail close to the inner rod, and the top of the limit block is rotatably connected to the slide rail through a bearing. It can be used in conjunction with components such as a humidity sensor, a baffle and a tension spring. During the use of the corrosion-resistant high-voltage distribution cabinet, the temperature inside the cabinet can be detected by the temperature sensor, and the external humidity can be detected by the humidity sensor. Whenever the temperature inside the cabinet is lower than the set threshold and the external humidity is higher than the set threshold, the processor issues an instruction, the electromagnet turns on to adsorb the iron block, and simultaneously drives the baffle to block the inside of the vent. On the contrary, the electromagnet is closed, and the tension spring drives the iron block and the baffle to move up and reset. This structure is used to selectively block the vents, avoid excessive humidity in the cabinet to a certain extent, and has a corrosion-resistant protective effect.

[0010] As an optional solution to the technical solution of the present application, a groove is provided on one side of the inner wall at the bottom of the slide rail, a micro switch is fixedly installed in the groove, and the indicator light is electrically connected to the micro switch through a wire, which can be used in conjunction with components such as a limit block and an indicator light.

The caregiver can know that the electromagnet is turned on through the indicator light, and according to the recent weather temperature and humidity conditions, the limit block can be selectively turned to limit the iron block and manually close the electromagnet. The electromagnet can be selectively closed under permitted external conditions, thereby avoiding complete reliance on the electromagnet for limiting and reducing the loss of electric energy.

[0011] As an optional solution of the technical solution of the present application, the data output ends of the temperature sensor and the humidity sensor are connected to the data input end of the processor, and the signal output end of the processor is connected to the signal input end of the electromagnet. The internal and external components can be connected by wires to realize the transmission of data and signals, thereby realizing the intelligent opening and closing of the electromagnet, which meets the practical needs.

[0012] As an optional solution to the technical solution of the present application, a plurality of groups of assembly racks in a uniform array are fixedly installed on the rear inner wall of the cabinet, and positioning holes are provided on both sides of the front inner wall of the assembly racks. The high-voltage components can be detachably fixed through the assembly racks and their positioning holes, and the detachable assembly facilitates later disassembly, maintenance and replacement.

[0013] As an optional solution of the technical solution of the present application, feet are fixedly installed at the four corners of the lower surface of the cabinet, and positioning holes are opened on both sides of the feet. The cabinet can be detachably fixed through the feet and the positioning holes to ensure the stability of the cabinet limit to prevent it from tipping over.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a corrosion-resistant high-voltage power distribution cabinet, which is provided with a humidity sensor, a baffle and a tension spring. During the use of the corrosion-resistant high-voltage power distribution cabinet, the temperature inside the cabinet can be detected by the temperature sensor, and the external humidity can be detected by the humidity sensor. Whenever the temperature inside the cabinet is lower than the set threshold value and the external humidity is higher than the set threshold value, the processor issues an instruction, the electromagnet turns on to adsorb the iron block, and simultaneously drives the baffle to block the inside of the vent, otherwise the electromagnet is closed, and the tension spring drives the iron block and the baffle to move up and reset.

During the use of the corrosion-resistant high-voltage distribution cabinet, the temperature inside the cabinet can be detected by the temperature sensor 14, and the external humidity can be detected by the humidity sensor 16. Whenever the temperature inside the cabinet is lower than the set threshold and the external humidity is higher than the set threshold, the processor 31 issues an instruction, the electromagnet 41 starts to adsorb the iron block 22, and simultaneously drives the baffle 2 to block the inside of the vent 15.

Whenever the temperature inside the cabinet is less than the set threshold and the external humidity is greater than the set threshold, the processor 31 issues an instruction, the electromagnet 41 turns on the adsorbed iron block 22, and simultaneously drives the baffle 2 to block the inside of the vent 15. On the contrary, the electromagnet 41 is closed, and the tension spring 42 drives the iron block 22 and the baffle 2 to move up and reset. This structure is used to selectively block the vent 15, and to avoid excessive humidity in the cabinet to a certain extent. It is wet and has corrosion-resistant protection.

The caregiver can know that the electromagnet 41 is turned on through the indicator light 13, and according to the recent weather temperature and humidity conditions (such as low temperature in winter and rainy days), the limit block 51 is selectively rotated. The limit block 51 limits the iron block 22 and manually closes the electromagnet 41. The electromagnet 41 can be selectively closed under allowed external conditions, thereby avoiding complete reliance on the electromagnet 41 for limiting and reducing the loss of electric energy.
