Description

Technical Field

[0001] The utility model belongs to the field of insulated ring main switch cabinets, and specifically relates to an insulated ring main switch cabinet. Background Art

[0002] An insulated ring main switch cabinet is a high-voltage device used in a power distribution system, usually used in the power distribution systems of places such as cities, industrial parks, mines, etc. It is usually installed outdoors and is used for operations such as branching, earthing, and breaking, so as to quickly isolate the faulty part and ensure the reliable operation of the system when a fault occurs in the power grid. Insulated ring main switch cabinets mainly include solid-insulated type and gas-insulated type. The solid-insulated ring main switch cabinet uses solid insulating materials as the insulating medium, and the gas-insulated ring main switch cabinet uses air or high-pressure gas as the insulating medium. Through the insulating medium, the high-voltage parts inside the cabinet can be isolated, thereby ensuring the safe operation of the equipment and the safety of personnel.

[0003] According to the Chinese patent application number: 202220554419.1, there is disclosed an insulated ring main switch cabinet, including a cabinet body. An installation groove is opened on one side of the cabinet body. A dehumidifying fan is movably installed inside the installation groove of the cabinet body. Two L-shaped support plates are fixedly connected to one side of the cabinet body corresponding to the dehumidifying fan. The inner wall of the L-shaped support plate is in contact with the bottom of the dehumidifying fan. A card slot is opened at the top of the L-shaped support plate. A clamping plate is movably connected inside the card slot of the L-shaped support plate. One side of the clamping plate is threadedly connected with a threaded rod. One end of the threaded rod is rotatably connected with a pressing plate. By turning on the dehumidifying fan, the dehumidifying fan discharges the moisture inside the cabinet body, thereby keeping the inside of the cabinet body dry, reducing the damage of the components inside the cabinet body, and delaying the service life. The L-shaped support plate supports the dehumidifying fan. By rotating the rotating rod, the threaded rod rotates on the clamping plate, so that the pressing plate moves and presses the dehumidifying fan, facilitating the stability of the dehumidifying fan.

[0004] The prior art effectively solves the problem that the inside of the insulated ring main switch cabinet is prone to moisture when used outdoors, and has the advantage of being able to dehumidify the inside of the cabinet body. However, in actual use, since the insulated ring main switch cabinet is usually installed outdoors, it requires regular inspections by staff. When a fault occurs in the insulated ring main switch cabinet, the staff cannot timely understand the situation, so they cannot take timely treatment measures, which in turn affects the normal operation of the insulated ring main switch cabinet.

The output end of the PID controller 301 is connected to the input end of the wireless transmission module 302. The output end of the wireless transmission module 302 is connected to the input end of a remote terminal.

[0024] As Figures 1-4 shown, the cabinet body 101 and the cabinet door 102 are used to provide an installation and protection space for the switch module 2 and the monitoring component 3.

[0025] Embodiment 2

[0026] Referring to Figures 1-4 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0027] In this embodiment, the number of temperature sensors 303 is two, and they are respectively installed at the upper end and the lower end of the back surface of the cabinet body 101.

The PID controller 301 summarizes and processes the data. When a fault is judged, the PID controller 301 sends a warning message to the remote terminal through the wireless transmission module 302, so as to remind the staff to take measures in time. When the temperature sensor 303 monitors that the temperature in the inner cavity of the cabinet body 101 is higher than the set value, the PID controller 301 starts the exhaust fan 104. The airflow generated by the high-speed rotation of the exhaust fan 104 can discharge the high-temperature airflow in the inner cavity of the cabinet body 101, so as to cool the inner cavity of the cabinet body 101.
