[0034] In the present embodiment: when the local distribution cabinet with built-in exposed wiring post protection device is in use, the protection plate 31 is placed inside the cabinet 1 by moving the limit plates 35 on both sides, and the protection plate 31 is moved to align the protection plate 31 with the wiring post of the electrical equipment, and the exposed wiring is shielded by the protection plate 31. Then the limit plate 35 will be pressed against the inner wall of the cabinet 1 by the elastic force of the spring 36 to limit the position of the protection plate 31. The exposed part of the connector is protected by the protection plate 31, thereby eliminating the safety hazard of exposed wiring post and reducing the incidence of electric shock accidents. Secondly, the device is easy to install, reduces the labor intensity of operators, and improves work efficiency. Finally, the device has a long service life, reduces maintenance costs, and brings tangible economic benefits to the company.

[0035] It should be noted that the protection plate 31 is made of high-strength transparent insulating material and has good electrical resistance and anti-aging properties.

[0036] Going further:

[0037] like Figures 1 - 4 As shown:

[0038] In order to improve the stability of the positioning of the protective plate 31, in an optional embodiment: the surface of the protective plate 31 is symmetrically fixedly connected with a safety mark 32; a screw 39 is rotatably connected inside the fixed plate 33, and a T-shaped block 38 is screwed on the surface of the screw 39, and the block 38 is slidably connected inside the fixed plate 33, and a movable groove is provided on one side of the limiting plate 35 close to the block 38; a worm gear 310 is fixedly sleeved on the surface of the screw 39, and a worm 311 is meshingly connected on the surface of the worm gear 310, and the worm 311 passes through the interior of the fixed plate 33 and is fixedly connected to a handle arranged on the surface of the fixed plate 33.

[0040] It should be noted that the end surfaces of the limiting plate 35 and the abutment block 38 are fixedly connected with rubber blocks to increase the friction between the limiting plate 35 and the inner wall of the cabinet 1 .

[0041] More specifically:

[0042] like Figures 1 - 4 As shown:

[0043] Combined with the above content, a heat dissipation component 4 is provided on the surface of the cabinet body 1. The heat dissipation component 4 includes ventilation pipes 41 symmetrically and fixedly connected to both sides of the surface of the cabinet body 1. Inside the ventilation pipes 41, fans 44 are symmetrically installed. On both sides of the fans 44, grid plates 42 and dust-proof nets 43 are respectively provided, and the grid plates 42 are fixedly connected to the cabinet body 1; the dust-proof nets 43 are installed inside the ventilation pipes 41 by bolts; a temperature sensor 45 is installed inside the cabinet body 1.

[0044] In this implementation plan: When the electrical equipment body 5 is working, it will generate heat, resulting in an increase in the temperature inside the cabinet body 1. Excessive temperature will reduce the service life of the electrical components inside the cabinet body 1. The temperature sensor 45 can monitor the temperature inside the cabinet body 1. When the temperature inside the cabinet body 1 is too high, the temperature sensor 45 can transmit an electrical signal to the controller inside the cabinet body 1, and through the controller, control multiple groups of fans 44 to start. By the fans 44, the air exchange inside the cabinet body 1 is accelerated, and the heat generated by the electrical components inside the cabinet body 1 can be extracted outside the cabinet body 1 to reduce the temperature inside the cabinet body 1, slow down the aging of the electrical components, and extend the service life. When the temperature inside the cabinet body 1 drops to a predetermined value, the temperature sensor 45 can control the fans 44 to turn off through the controller, realizing automatic cooling inside the cabinet body 1. The grid plates 42 can protect the fans 44, and the dust-proof nets 43 can prevent external dust from entering the inside of the cabinet body 1. Moreover, the dust-proof nets 43 are installed on the surface of the ventilation pipes 41 by bolts, and the dust-proof nets 43 can be disassembled for cleaning or replacement.

[0046] Working principle: When the local power distribution cabinet with built-in exposed wiring post protection device is in use, the protection plate 31 is placed inside the cabinet 1 by toggling the limit plates 35 on both sides, and the protection plate 31 is moved to align the protection plate 31 with the wiring post of the electrical equipment, and the exposed wiring is shielded by the protection plate 31. Then, the limit plate 35 will be pressed against the inner wall of the cabinet 1 by the elastic force of the spring 36 to limit the position of the protection plate 31, and the exposed part of the terminal is protected by the protection plate 31. The worm gear 310 can be driven to rotate by rotating the worm 311, and then the worm gear 310 will drive the stop block 38 outward through the screw 39, drive the stop block 38 to press against the inner wall of the cabinet 1, lock the position of the protection plate 31, and improve the stability of the installation of the protection plate 31. The electrical equipment body 5 will generate heat when working, causing the temperature inside the cabinet 1 to rise. Excessive temperature will reduce the electrical components inside the cabinet 1 The service life of the cabinet 1 can be extended by monitoring the internal temperature of the cabinet 1 through the temperature sensor 45. When the internal temperature of the cabinet 1 is too high, the temperature sensor 45 can transmit an electrical signal to the internal controller of the cabinet 1, and control the multiple sets of fans 44 to start through the controller. The fans 44 accelerate the air exchange inside the cabinet 1, and the heat generated by the electrical components in the cabinet 1 can be drawn out of the cabinet 1 to reduce the internal temperature of the cabinet 1, slow down the aging of the electrical components, and extend the service life. When the internal temperature of the cabinet 1 drops to a predetermined value, the temperature sensor 45 can control the fans 44 to be turned off through the controller to achieve automatic cooling of the inside of the cabinet 1. The fans 44 can be protected by the grid plate 42, and the dustproof net 43 can prevent external dust from entering the inside of the cabinet 1. The dustproof net 43 is installed on the surface of the ventilation pipe 41 by bolts, and the dustproof net 43 can be disassembled, cleaned or replaced.
