Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology for high-voltage equipment, and in particular to a novel dehumidification device for a high-voltage slip ring box of a gantry crane. Background Technology

[0002] High-voltage slip ring boxes are important components in large equipment such as gantry cranes. They carry out the guiding and supporting functions of high-voltage cables, ensuring that the high-voltage cables can move and connect flexibly during the operation of the equipment. At the same time, they play a role in electrical insulation, ensuring the safety and stability of power transmission.

[0003] High-voltage slip ring boxes are exposed to high temperatures, high humidity, and corrosive substances in the air for extended periods. In such an environment, moisture from the outside air easily enters the high-voltage equipment and condenses into water droplets on the internal insulation. This condensation not only reduces the equipment's insulation capacity but can also directly cause cable short circuits, leading to equipment failure or shutdown. Furthermore, prolonged exposure to humidity can corrode internal spare parts, severely impacting the equipment's lifespan. Traditional dehumidification methods to address this issue include rust removal from copper plates, replacement of high-voltage insulators, alcohol wiping, placement of desiccants, and high-temperature baking.

[0004] While existing dehumidification methods can alleviate equipment corrosion to some extent, they often require manual repetition during actual operation, which is time-consuming and labor-intensive. Utility Model Content

[0005] This application provides a novel dehumidification device for a high-pressure slip ring box of a gantry crane, which solves the problem of the time-consuming and laborious process of dehumidifying the high-pressure slip ring box in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel dehumidification device for a high-pressure slip ring box of a gantry crane, comprising a slip ring box body, a transformer breather and a duct dehumidifier installed on the outside of the slip ring box body, both of which are connected to the inside of the slip ring box body through pipes; a temperature and humidity controller, a temperature and humidity sensor and a heating plate are installed inside the slip ring box body, wherein the temperature and humidity sensor and the heating plate are electrically connected to the temperature and humidity controller.

[0007] Because the slip ring box is equipped with a temperature and humidity controller, a temperature and humidity sensor, and a heating plate, the humidity of the environment can be monitored in real time inside the slip ring box. When the humidity is higher than the set value, the sensor sends a signal to the temperature and humidity controller, which then controls the heating plate to heat the air. At the same time, the duct dehumidifier is connected to the inside of the slip ring box through a pipe to extract excess moisture from the slip ring box. This process does not require manual operation, saving time and effort.

[0008] Further, the bottom of the slip ring box body is fixed to the base below by the bottom foot through bolt connection, wherein the bottom foot is provided with spring washers, and the bolt is connected to the base after penetrating through the spring washers and the bottom foot; thus, the bolt can be effectively prevented from loosening under the action of vibration or external force, so that the installation of the slip ring box body is more stable.

[0009] Further, the base is also fixed with a support, which is fixed to the side of the base and supported below the pipeline dehumidifier, and the pipeline dehumidifier is connected to the bottom of the slip ring box body through a pipeline; the bottom is usually a region where moisture accumulates more seriously, and connecting the pipeline dehumidifier to the bottom of the slip ring box body can more effectively extract the moisture accumulated in the bottom, avoid the accumulation of moisture in the slip ring box, and ensure the dry environment inside the equipment.

[0010] Further, a valve is installed on the pipeline connected between the pipeline dehumidifier and the slip ring box body; thus, by adjusting the opening of the valve, the working efficiency and dehumidification capacity of the dehumidifier can be flexibly adjusted to adapt to different working environments and dehumidification requirements.

[0011] Further, the transformer breather is fixed to the side of the slip ring box body, wherein the side of the slip ring box body is fixed with two bolts, and the transformer breather is nested with a hoop, and the two sides of the hoop are fixed to the bolts on the side of the slip ring box body through nuts.

[0012] Further, the slip ring box body is wrapped with thermal insulation cotton; the thermal insulation cotton can effectively reduce the heat exchange between the slip ring box body and the external environment, thereby reducing the temperature difference between the inside and outside of the slip ring box body, and thereby reducing the probability of condensate water caused by excessive temperature difference.

[0013] The above technical scheme can achieve at least the following technical effects or advantages:

[0014] The transformer breather, the pipeline dehumidifier, the temperature and humidity controller, and the temperature and humidity sensor in the device work cooperatively. The transformer breather can pretreat the air entering the slip ring box to absorb the moisture and impurities in the air. Meanwhile, the pipeline dehumidifier is connected to the inside of the slip ring box body through a pipeline to extract the excess moisture in the slip ring box. Inside the slip ring box, the temperature and humidity sensor monitors the humidity of the environment in real time, and when the humidity is higher than the set value, the temperature and humidity sensor sends a signal to the temperature and humidity controller, which immediately controls the heating plate to heat and dehumidify. In addition, the thermal insulation cotton wrapped outside the slip ring box helps to reduce the temperature difference between the inside and outside, and reduce the generation of condensate water caused by excessive temperature difference. The whole device effectively realizes the dehumidification and protection of the dehumidifier high-voltage slip ring box through the cooperation of various components, without manual operation, saving time and effort.
