Description

A moisture-proof switch cabinet

technical field

The utility model relates to a moisture-proof switch cabinet, which belongs to the technical field of power supply equipment.

Background technique

Switchgear is one of the most important electrical equipment in substations and power plants. The switchgear is generally installed on the basis of the cable trench. The primary cable passes through the bottom of the cabinet and is connected to the wiring board of the switchgear. The bottom of the switchgear should be sealed to keep the switchgear in a sealed state. During the long-term operation of the switchgear, due to the harsh environment, when the bottom plate of the cabinet is not sealed in place, the moisture in the cable trench under the cabinet will continue to penetrate into the switchgear. After the moisture enters the switchgear cabinet. It will cause condensation on the equipment in the switchgear and reduce the insulation of the equipment. In severe cases, it will cause the insulation flashover of the switchgear, affecting the operation safety and service life of the switchgear. Therefore, it is particularly important to protect the bottom of the switchgear from moisture. It is necessary to carry out moisture-proof treatment on the switchgear.

Utility model content

The purpose of the utility model is to provide a moisture-proof switchgear, through the inlet fan and the outlet fan installed in the base and the switchgear, the moisture in the cabinet can be discharged more thoroughly. Openings on the base and electric heating pipes inside the switchgear can ventilate and dry the wet bottom. The moisture in the gas in the cable trench is absorbed, which prevents the moisture in the cable trench from penetrating into the switchgear cabinet to form tiny water droplets to drop on the insulating surface of the equipment, avoiding insulation flashover and insulation aging, and at the same time, the temperature and humidity are controlled. The monitoring improves the reliability of power supply and solves the above-mentioned problems in the background technology.

The technical scheme of the utility model is:

A moisture-proof switch cabinet, including a switch cabinet, a base, a temperature and humidity display, an inlet fan, an outlet fan, an air inlet hole, an air outlet hole, an electric heating pipe, an air inlet, an air outlet, an upper partition, a lower partition, and a vent , a lower cavity, an upper cavity, a base cavity, and a temperature and humidity sensor, the base is provided with a base cavity, the base is provided with a switch cabinet, the side of the base is provided with an air inlet, and the air inlet communicates with the base cavity , there is a vent between the top of the base and the bottom of the switch cabinet, the vent is connected to the inner cavity of the base, and the air inlet is arranged in the inner cavity of the base; the outlet fan, electric heating tube, upper partition, lower partition and temperature The sensors are all installed inside the switch cabinet. The upper partition and the lower partition are respectively arranged at the upper and lower ends of the switch cabinet. There is a lower chamber between the lower partition and the bottom of the switch cabinet. There is an upper cavity between them, the electric heating tube is set in the lower cavity, the outlet fan is set in the upper cavity, the side of the switch cabinet is provided with an air outlet, and the air outlet is connected with the upper cavity; the upper partition and the lower partition An air outlet and an air inlet are respectively provided; a temperature and humidity display is provided on the switch cabinet, and the temperature and humidity display is connected with a temperature and humidity sensor.

At least one side of the base is provided with an opening, and the opening communicates with the inner cavity of the base

The opening is provided with a filter layer covered with activated carbon or moisture-proof agent.

The temperature and humidity sensor is wired or wirelessly connected to the temperature and humidity display.

There are several air outlet holes and air inlet holes, which are evenly arranged on the upper partition and the lower partition.

The positive effect of the utility model: avoiding the moisture in the cable trench from penetrating into the switchgear cabinet to form tiny water drops falling on the insulating surface of the equipment, avoiding insulation flashover and insulation aging, and monitoring the temperature and humidity at the same time, improving the reliability of power supply.
