Abstract
Description
Technical Field
[0001] The utility model relates to an improved electric control cabinet. Background Art
[0002] Industrial production environments are often harsh, with high temperatures and high humidity in summer and low temperatures and humidity in winter. Due to the special environment, electrical control cabinets must be able to operate normally to ensure the normal operation of the electrical components inside. In an environment with high humidity and large temperature differences, condensation is very likely to occur, which in turn causes corrosion to the power transmission and distribution equipment, which in turn has a great impact on the electrical and mechanical properties of the equipment, ultimately leading to reduced insulation of electrical equipment, and ultimately causing failures in the power transmission and distribution process. When condensation occurs in the outdoor controller, the traditional control methods are mainly the following three: minimizing the humidity in the control cabinet; ensuring that the internal temperature of the control cabinet is higher than the external temperature; and enhancing the convection of air inside and outside the control cabinet through axial flow fans. However, some wires close to the heater are susceptible to long-term high temperatures and are prone to aging of insulation components and reduced insulation performance, which affects normal use. Utility Model Content
[0003] The utility model provides an improved electrical control cabinet, which is used to solve the problem in the background technology that some wires relying on heaters are susceptible to insulation aging due to long-term high temperature, and rely on forced ventilation to dissipate heat and reduce moisture, which leads to a reduction in final performance and affects normal use.
[0004] To achieve the above objectives, the utility model is implemented through the following technical scheme, an improved electrical control cabinet: including a cabinet body, upper and lower ends of one side of the cabinet body are fixedly connected with rectangular mounting seats, a cabinet door is movably connected to the side opposite to the rectangular mounting seat, a rubber strip is fixedly connected to one side of the cabinet door, an annular baffle is fixedly connected to one side of the cabinet body, a mounting tube is fixedly connected to the top wall of the cabinet body, a fan assembly is installed inside the mounting tube of the cabinet body, and an observation window is fixedly connected to the other side of the cabinet door.
[0005] A circular groove is opened on the upper surface of the cabinet body, a cover plate is movably connected to the inner side of the circular groove, and guide columns evenly arranged around the center line of the cover plate are fixedly connected to the lower surface of the cover plate.
[0006] Both sides of the cabinet of the utility model are fixedly connected with arc plates, and the inner side of the arc plates is movably connected with a flap. A semiconductor dehumidifier core is installed on one side of the inner wall of the cabinet, and the outlet end of the semiconductor dehumidifier core is connected with a drain pipe. A threaded rod is fixedly connected to the lower surface of the cabinet, and a hollow rod is threadedly connected to the surface of the threaded rod, and one end of the hollow rod is fixedly connected to a support sheet, and a through hole is opened on the upper surface of the support sheet, and a grounding bolt is inserted into the inner side of the through hole. Support rods are fixedly connected to the four corners of the upper surface of the cabinet, and a shielding plate is fixedly intercepted at one end of the support rod. A mounting seat is fixedly connected to one side of the cabinet, and a locking screw is movably connected to the inner side of the mounting seat, and a step cap is threadedly connected to one end of the locking screw, and a holder is fixedly connected to one side of the cabinet door.
[0007] When in use, the staff first seals the front of the device with locking bolts and rubber strips, and fills the gap of the wiring hole at the bottom with a reserved caulking ring. Then the staff starts the semiconductor dehumidifier core through the control switch, so that it can convert the water vapor in the device into water droplets and discharge them. The setting of the flap and cover enables the device to form a relatively stable closed environment when no ventilation is performed, reducing the exchange of air inside the device and external gas, so that the water vapor in the device is maintained at a low level, thereby achieving the effects of moisture-proof, high-temperature proof and low-temperature proof, and can be effectively applied to various special environmental requirements.
