Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a high-voltage switch cabinet with a leakage protection device. Background Art

[0002] With the continuous innovation and development of switch cabinets, the level of manufacturing technology has been gradually improved to meet the needs of various functions, which has greatly improved the functionality of switch cabinets. Various types of switch cabinet products are constantly developing and updating, and there is still room for further improvement in the structure of switch cabinets. Most traditional switch cabinets use heat dissipation slots to dissipate heat. However, the heat dissipation slots are prone to dust entering and affecting the switch equipment.

[0003] The patent with application number 202022495588.6 discloses a switch cabinet that is easy to wire and has a leakage protection device, including a cabinet body, a protective tube, a cover plate and a heat sink. A movable shaft is installed on the inner side of the cabinet body, and an access pipe is provided on the inner side of the movable shaft. A three-phase line is provided on the inner side of the access pipe, and a leakage protector is installed on the end of the three-phase line. A connecting wire is provided on the side of the leakage protector, and a fixed sleeve is provided on the outer side of the connecting wire, and a rotating shaft is provided on the outer side of the fixed sleeve.

[0004] The above technical solution dissipates heat through a heat sink with a mesh and blocks it through a top plate. However, during the heat dissipation process, dust will still enter the heat sink from the side wall of the top plate and affect the use of the switch device. At the same time, the above technical solution uses the parts on the partition plate for wiring. The partition plate not only reduces the internal space of the switch cabinet, but also affects the heat transfer between different devices. Utility Model Content

[0008] Furthermore, a wire protection tube is embedded and fixed at the bottom end of the side wall of the switch cabinet body, and a plurality of wire positioning frames are fixed to the bottom wall of the switch cabinet body.

[0009] Furthermore, a plurality of heat sinks are fixed at equal intervals on the side wall of the heat absorbing plate, and a plurality of fans are embedded in the wind box.

[0010] Furthermore, ventilation slots connected to the fan are arranged between the plurality of heat sinks, and dustproof nets are installed at both ends of the fan.

[0011] Furthermore, a plurality of clips are fixed at equal intervals on the side wall of the equipment mounting plate, and a leakage protection switch is clipped and mounted on the clips.

[0012] Furthermore, the wire fastening block is provided with a wire fastening groove which is larger than one-half of a circle, and the inner wall of the wire fastening block is provided with a mounting groove.

[0013] Furthermore, a bolt is embedded in the installation groove, and one end of the bolt passes through the wire fastening block and is threadedly inserted into the screw hole.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model fixes an equipment mounting plate for mounting a leakage protection switch on the inner wall of the switch cabinet body, and a groove is provided on the outer wall of the switch cabinet body.
