[0023] like Figure 1-4 As shown, a high-voltage outgoing line cabinet that facilitates later maintenance includes a cabinet body 1, a front door 3, and a rear door 4. The front door 3 is located on the front side of the cabinet body 1, and the rear door 4 is located on the back side of the cabinet body 1. By setting the front door 3 and the rear door 4, the cabinet body 1 can be opened at both ends, thereby avoiding the need for maintenance personnel to choose the appropriate direction for maintenance based on the specific situation inside the cabinet body 1, and reducing the difficulty of maintenance.

[0024] To facilitate heat dissipation inside the cabinet 1, the high-voltage outgoing cabinet provided in this embodiment, which is convenient for later maintenance, also includes a wind chamber 2. The wind chamber 2 is fixed to the upper end of the cabinet 1. The projected area of ​​the wind chamber 2 on the horizontal plane is larger than the projected area of ​​the cabinet 1 on the horizontal plane, and an air outlet 8 is provided at the part where the two projected areas do not overlap. A circulating fan 9 is provided inside the wind chamber 2, and a ventilation port is provided on the air inlet end of the circulating fan 9 located in the wind chamber 2. By improving the ventilation path, the heat dissipation inside the equipment is accelerated, and the air outlet 8 is opened downwards to prevent rainwater and dust from seeping into the equipment, thereby extending the maintenance cycle of the electrical components inside the equipment.

[0025] like Figure 2 and Figure 4 As shown, to facilitate the organization of cables inside cabinet 1, the high-voltage outgoing cabinet provided in this embodiment, which is convenient for later maintenance, also includes a second vertical support 11 and a wire clamp 12. The second vertical support 11 is fixed inside the air chamber 2 near one side, and the wire clamp 12 is slidably installed on the second vertical support 11. The wire clamp 12 and the second vertical support 11 can be fastened together by bolts. It should be further explained that the wire clamp 12 is sleeved on the second vertical support 11, and a bolt is installed on the wire clamp 12 by thread rotation. The other end of the bolt passes through the wire clamp 12 and is equipped with an anti-slip pad. Rotating the bolt causes the anti-slip pad to abut against the second vertical support 11, thereby locking the wire clamp 12. In this way, the height position of the wire clamp 12 can be adjusted to improve the practicality of the equipment and facilitate the later maintenance of electrical components inside cabinet 1.

[0026] like Figure 5 and Figure 6 As shown, to facilitate the maintenance of internal electrical components, the high-voltage outgoing cabinet provided in this embodiment also includes a first vertical support 10. There are two sets of first vertical supports 10, which are symmetrically arranged on the side of the cabinet 1 near the front door 3.

There is also a circuit breaker 6, with both ends of the circuit breaker 6 mounted on the first vertical support 10, and a protective cover is hinged to the front surface of the circuit breaker 6.

[0027] It should be noted that the first vertical support 10 has an "L" shaped structure, and slots are evenly arranged on the first vertical support 10 from top to bottom. Both ends of the mounting frame 7 and the circuit breaker 6 are provided with locking posts that engage with the slots. By engaging the slots with the locking posts, it is convenient to adjust the installation height of the mounting frame 7 and the circuit breaker 6 and to disassemble them later, thereby improving the practicality of the equipment.

[0028] like Figure 1 and Figure 5 As shown, in order to facilitate the airflow circulation inside and outside the equipment, the high-voltage outgoing cabinet provided in this embodiment for easy maintenance also includes a vent 5. The vent 5 is symmetrically arranged on both sides of the cabinet 1 near the lower end to facilitate the input of external air. The vent 5 is also equipped with a moisture-proof protective net that can be detachably installed inside, thereby reducing the moisture content in the air and improving the service life of the equipment.

[0029] like Figure 1 As shown, to facilitate the use of the front door 3 and the rear door 4, one side of the front door 3 and the rear door 4 provided in this embodiment are hinged to the cabinet 1, and the other side of the front door 3 and the rear door 4 are snapped together with the cabinet 1.

[0030] The working principle and usage process of this utility model: When in use, the front door 3 and the rear door 4 are set to realize the double opening of the front and rear ends of the cabinet 1, thereby avoiding the need for maintenance personnel to choose the appropriate direction for maintenance according to the specific situation inside the cabinet 1, and reducing the difficulty of maintenance.

[0031] During maintenance, the mounting bracket 7 and the circuit breaker 6 can be easily adjusted and disassembled by the snap-fit ​​of the slot and the snap-fit. The anti-slip pad is made to abut against the second vertical bracket 11 by rotating the bolt, thereby locking the wire clamp 12 and adjusting the height of the wire clamp 12. This improves the practicality of the equipment and facilitates the later maintenance of the electrical components inside the cabinet 1. In addition, by improving the ventilation path, the heat dissipation inside the equipment is accelerated, and the air outlet 8 is made to face downwards to prevent rainwater and dust from seeping into the equipment and extend the maintenance cycle of the electrical components inside the equipment.
