It is usually installed in the substation or distribution room to provide the functions of power conversion, control, protection and distribution. The low-voltage distribution cabinet is suitable for various industrial, commercial and residential power occasions to ensure the reliability, safety and stability of the power supply.

[0003] A circuit breaker and other electrical equipment are generally installed inside a power distribution cabinet. When installing a relay in an existing power distribution cabinet, a hole needs to be drilled in the cabinet body, and then the relay is fixed to the cabinet body with screws. Although the relay can be fixed to any position of the power distribution cabinet.

[0004] However, with the existing power distribution cabinets, when a large number of relays need to be installed, the staff need to repeatedly drill holes in the power distribution cabinet for installation, which is troublesome and inconvenient to isolate the relays. As a result, when one of the relays leaks electricity, it is easy to affect other nearby relays, resulting in poor safety. Therefore, a low-voltage AC power distribution cabinet that is convenient for installing multiple circuit breakers is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that when a large number of relays need to be installed, the staff need to repeatedly drill holes in the distribution cabinet before they can be installed, which is rather troublesome and inconvenient to isolate the relays. As a result, when one of the relays leaks electricity, it is easy to affect other nearby relays, resulting in poor safety.

[0006] To achieve the above object, the utility model provides the following technical solution: a low-voltage AC power distribution cabinet that facilitates the installation of multiple circuit breakers, comprising a power distribution cabinet body and a mounting plate, wherein an isolation mounting structure is provided inside the power distribution cabinet body;

[0026] The isolation installation structure includes a strip groove 3, a threaded positioning hole 4 and a mounting hole 8 opened on the front side of the mounting plate 2, a sleeve rod 5 is fixedly connected inside the strip groove 3, an isolation plate 6 is slidably connected to the inner side of the sleeve rod 5, a threaded column 7 is fixedly connected to the inner wall of the distribution cabinet body 1, the threaded column 7 passes through the mounting hole 8, a locking nut 9 is threadedly sleeved on the outer surface of the threaded column 7, a through hole 10 for cable routing is opened on the back side of the distribution cabinet body 1, a fixing ring 11 is fixedly connected to the inner side of the through hole 10, and a rubber insulating sheet 12 is fixedly connected to the inner side of the fixing ring 11. When the relay needs to be installed, since the front side of the mounting plate 2 has several threaded positioning holes 4, the staff does not need to constantly drill holes in the distribution cabinet body 1, which is more convenient.

[0027] Among them, it is only necessary to move the isolation plate 6 to make it slide on the outer surface of the sleeve rod 5 to install multiple relays in isolation, so as to avoid affecting other nearby relays when one of the relays leaks electricity, which has better safety. In addition, when relays of different sizes need to be installed, the staff only needs to customize the number of installation plates 2 and the relative distance of the isolation plate 6 to adapt according to relays of different sizes.

[0028] In addition, the cooperation among the through hole 10 , the fixing ring 11 and the rubber insulating sheet 12 can facilitate the routing of cables, and multiple cables can pass through the through hole 10 at the same time and be insulated and isolated by the rubber insulating sheet 12 .

[0029] There are four mounting plates 2 , which are evenly distributed inside the power distribution cabinet body 1 .

[0030] It should be noted that the back side of the locking nut 9 is pressed against the front side of the mounting plate 2 , and the mounting plate 2 is in the shape of a bar.

[0031] Embodiment 2:

Through the cooperation of the partition 13, the equipment box 14, the protective door 17, the sound-absorbing sponge layer 15 and the glass fiber flame-retardant layer 16, the electrical equipment and the relay can be installed in isolation, thereby avoiding the mutual influence between the two. At the same time, it can reduce noise and flame retardant effects, and has good practicality.

[0036] During installation, the staff first needs to align the mounting hole 8 of the mounting plate 2 with the threaded column 7 and insert it so that the threaded column 7 passes through the mounting hole 8, and then tighten the locking nut 9 clockwise to the outer surface of the threaded column 7, and make the back of the locking nut 9 press against the front of the mounting plate 2, so that the four mounting plates 2 can be installed equidistantly inside the distribution cabinet body 1. When it is necessary to install the relay, since the front of the mounting plate 2 has a number of threaded positioning holes 4, the staff does not need to continuously drill holes on the distribution cabinet body 1, which is more convenient. Among them, it is only necessary to move the isolation plate 6 so that it is on the outer surface of the sleeve rod 5. By sliding, multiple relays can be installed in isolation, so as to avoid affecting other nearby relays when one of the relays leaks electricity, which has better safety. In addition, when relays of different sizes need to be installed, the staff only needs to customize the number of mounting plates 2 and the relative distance of the isolation plates 6 to adapt them according to relays of different sizes. In addition, through the cooperation of the through hole 10, the fixing ring 11 and the rubber insulating sheet 12, it can facilitate the routing of cables, and multiple cables can pass through the through hole 10 at the same time, and be aligned and insulated by the rubber insulating sheet 12.
