Description

New heat dissipation and moisture-proof central cabinet

technical field

The utility model belongs to high-voltage power distribution equipment, in particular to a novel heat dissipation and moisture-proof central cabinet.

Background technique

The modular structure of the central cabinet brings great convenience to the installation, maintenance and operation of the switch cabinet, and guarantees the safety of equipment and personal safety. There are two installation methods for the grounding switch of the central cabinet: rear and central. When the grounding switch is placed at the rear, cable construction or maintenance must be done through the front lower door of the central cabinet, which is inconvenient for construction; when the grounding switch is central, cable construction or maintenance can be entered through the rear lower door. In addition, there are many electrical equipment in the closed central cabinet. When the peak load and the ambient temperature in summer are high, it is necessary to detect the heating of the contacts in the central cabinet to ensure the normal operation of the central cabinet; in winter, the temperature is low At the same time, it is also necessary to prevent condensation from falling on the electrical equipment in the central cabinet. The central cabinet is prone to insulation flashover accidents in humid environments. In order to avoid the problem of excessive temperature and humidity in the central cabinet, cooling fans and heating and dehumidification devices are generally added inside. Since the temperature and humidity in the central cabinet cannot be monitored and automatically controlled, the cooling fan and heating and dehumidification device Accelerated aging and damage or can not play its due role.

Utility model content

The purpose of the utility model is to provide a new heat dissipation and moisture-proof central cabinet with a central grounding switch that can monitor and automatically control the temperature and humidity in the central cabinet, so as to overcome the above-mentioned defects in the prior art.

The utility model is realized by adopting the following technical solutions: a new type of heat dissipation and moisture-proof central cabinet, which includes a cabinet body with the same front and rear heights, a middle partition board is arranged inside the cabinet body, and an instrument room is arranged on one side of the middle partition board , circuit breaker room, cable room, a handcart is provided in the circuit breaker room, a busbar room and a grounding switch are provided on the other side, and the grounding switch is fixed on the intermediate partition, the cable room, instrument room, circuit breaker Each room is equipped with a comb-shaped aluminum alloy heating plate, humidity sensor, exhaust fan and temperature sensor. The exhaust fan, temperature sensor, heating plate and humidity sensor are connected to the controller with a communication port. Features ventilation holes.

The cabinet body is provided with a pressure relief hole for installing a one-way valve.

The busbars in the busbar chamber are arranged in a vertical line.

The instrument room is integrated with the cabinet body.

The depth of the cabinet is 1600mm-1800mm.

Compared with the prior art, the beneficial effect of the utility model is: the utility model can automatically sense the temperature and humidity inside the cabinet, and when the temperature and humidity exceed the preset value, the control system controls the operation of the cooling fan to cool down or control the heating The device heats up and dries, and the utility model device greatly improves the efficiency of cooling and dehumidification, and the dehumidification effect is good, the degree of automation is high, no manual adjustment is required, and the service life of the working components is prolonged; and it can automatically and quickly release pressure, with pressure relief time Advantages of short length and high security.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a new heat dissipation and moisture-proof central cabinet includes a cabinet body 1 with the same front and rear heights, a middle partition 3 is arranged inside the cabinet body 1, and an instrument room 2 and a circuit breaker room are arranged on one side of the middle partition 3 5. The cable room 7 and the circuit breaker room 5 are equipped with a handcart 6, and the other side is equipped with a busbar room 4 and a grounding switch 8. The instrument room 2 and the cabinet body 1 are integrally structured, and the busbar in the busbar room 4 is a vertical one. Glyph layout; grounding switch 8 is fixed on the middle partition 3.

The cable room 7, the instrument room 2, and the circuit breaker room 5 are each equipped with a comb-shaped aluminum alloy heating plate, humidity sensor, exhaust fan and temperature sensor, and the exhaust fan, temperature sensor, heating plate and humidity sensor are connected to the controller with a communication port. Ventilation holes are arranged on the upper and lower panels and the left and right side panels of the middle partition 3 and the cabinet body 1.

The cabinet body 11 is provided with a pressure relief hole for installing a one-way valve, which further enhances the pressure relief speed, and avoids the bad influence of external humid air entering the cabinet body 11 on the electronic components.

The depth of the cabinet 1 is 1600mm-1800mm. When the overhead outlet cabinet is used for the incoming line of the busbar bridge of the main transformer cabinet, the effective distance from the live part to the rear panel of the bus room is greater than 125mm. The depth of the cabinet 1 within this range can meet the safety distance requirements .
