Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a solid insulation ring network cabinet. Background Art

[0002] The use of electric energy is indispensable in our lives. Electric energy generally needs to be transmitted using an electric power system. Among them, the solid-insulated ring main unit is an important control device in the power distribution system, which is used to control the on and off of the power transmission line. A solid-insulated cabinet movement is usually provided inside the solid-insulated ring main unit. The two ends of the solid-insulated cabinet movement are respectively connected to the power line bus and the cable. When the solid-insulated cabinet movement is closed inside, the high-voltage electrical signal in the power line bus is output through the cable. It is simple and convenient to use. In order to improve the heat dissipation efficiency inside the cabinet, heat dissipation holes are often opened on the side walls of the cabinet to facilitate air circulation, but there is generally a lack of filtering devices, so dust will also enter the interior of the cabinet, thereby affecting the safety of the electrical components inside the cabinet. There are also filters installed, but the filters are generally installed inside the cabinet, which makes cleaning and maintenance more troublesome. For this reason, we propose a solid-insulated ring main unit. Utility Model Content

[0010] Furthermore, tension springs are provided inside the grooves at the front end of the slide seat, and the opposite inner ends of the two tension springs are fixedly connected to the adjacent L-shaped inserts respectively, so that the tension springs limit the free movement of the L-shaped inserts.

[0011] Furthermore, handles are symmetrically provided on the front side of the protective cover, and the two handles are located between the two L-shaped inserts to facilitate pulling out the protective cover.

[0012] Furthermore, strip-shaped slides are symmetrically arranged on the upper surface of the cabinet, and symmetrically distributed dustproof plates are slidably connected between the two strip-shaped slides. The dustproof plates correspond to the positions of the wire inlet holes on the upper surface of the cabinet to prevent dust from falling into the interior of the cabinet through the wire inlet holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the solid insulation ring network cabinet has the following advantages:

[0014] 1. When it is necessary to enhance the heat dissipation effect inside the cabinet during use, the control switch can be adjusted to make the fan blow to the rear side, and then the air inside the cabinet is discharged from the heat dissipation holes of the cabinet, and then the outside air is supplemented to the inside of the fan through the small holes of the protective cover, the filter holes of the filter net, and the large holes of the support cover through the guide cover, and then enters the inside of the cabinet, thereby speeding up the flow speed of the air inside the cabinet and improving the heat dissipation effect of the electrical components inside the cabinet. The fan can speed up the circulation speed of the air inside the cabinet, and the air can be filtered through the filter net to prevent dust from entering the inside of the cabinet, which is beneficial to improve the safety of equipment use and greatly extend the service life of the equipment.

[0015] 2. When the filter needs to be cleaned and maintained after being used for a long time, you can hold the handles with both hands and then press the L-shaped strip in the direction close to the handle. The L-shaped strip and the slide seat slide relative to each other, and then the head of the L-shaped strip moves out of the inside of the socket and stretches the tension spring. After the head of the L-shaped strip moves out of the inside of the socket, pull the handle forward, and then the handle will drive the protective cover to move forward and separate from the support cover, so that the filter can be cleaned and maintained. The filter can be disassembled simply and conveniently, and it can be disassembled from the front side of the box door. There is no need to open the cabinet door for maintenance, which can effectively avoid electric shock accidents, thereby not only improving the convenience of maintenance, but also improving the safety during maintenance.
