Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet with cable top entry and exit. Background Technology

[0002] Distribution cabinets are key devices in power distribution systems for distributing electrical energy and controlling and protecting electrical equipment. Traditional distribution cabinets mostly adopt the bottom-in, bottom-out cable type, which relies on underground cable trenches pre-laid in the distribution room to complete the introduction and exit of cables. In this mode, cables need to enter from the bottom of the distribution cabinet through underground trenches, be distributed by the equipment inside the cabinet, and then return to the cable trench from the bottom and extend to the power terminal. With the acceleration of urbanization and the diversification of power distribution scenarios, its limitations have gradually become apparent. These limitations are mainly reflected in the following aspects: First, some distribution rooms do not have cable trenches due to power distribution scenarios, actual power distribution needs, or other reasons, and traditional bottom-in, bottom-out cable distribution cabinets cannot adapt to these scenarios. Second, the internal environment of cable trenches is closed and humid, which easily accumulates water, dust, or corrosive gases. Long-term operation may lead to cable insulation aging, short circuits, or even leakage risks. In addition, cable trenches are prone to becoming habitats for insects and rodents, causing damage to the cable protective layer. Maintenance personnel need to enter the narrow trenches to troubleshoot faults, which poses a personal safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a cable-in / out type distribution cabinet to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cable-in / out type distribution cabinet includes a cabinet body. A base plate is fixedly installed at the bottom of the cabinet body, and a cable mounting beam is fixedly installed on the base plate. An upper partition is fixedly installed in the upper left part of the cabinet body. The upper partition is parallel to the rear side plate of the cabinet body, and a cable channel is formed between the upper partition and the rear side plate. A cable fixing bracket is installed at the bottom of the upper partition. One end of the cable fixing bracket is fixedly connected to the upper partition, and the other end is fixedly connected to the cabinet body. A cover plate is fixedly installed on the top of the cabinet body. The cover plate has a cable through hole located above the cable channel. An instrument compartment is fixedly installed in the upper right part of the cabinet body. An instrument compartment side plate is fixedly installed on the left side of the instrument compartment. The instrument compartment side plate has a secondary cable through hole.

[0006] Furthermore, a cable is inserted through the cable through hole, with one end of the cable connected to the vacuum circuit breaker along the cable channel, cable fixing frame, and cable mounting beam, and the other end passing through the cable through hole to connect to external equipment.

[0007] Furthermore, the cable mounting beam and cable fixing frame are equipped with cable clamps for fixing the cables.

[0008] Furthermore, a first sealing ring is installed in the cable through hole, and a second sealing ring is installed in the secondary cable through hole.

[0009] Furthermore, a rear upper door is provided on the upper left side of the cabinet, and the rear upper door is hinged to the cabinet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model achieves a top-in, top-out power distribution method for cables by setting up cable channels inside the cabinet and opening cable through holes in the cabinet cover and instrument room side panel, which meets the needs of working scenarios without cable trenches. At the same time, it avoids the risks of aging, short circuits, and damage from insects and rodents in traditional bottom-in, bottom-out cable distribution. It has the characteristics of simple structure, low cost, and convenient installation. Attached Figure Description
