Problems solved by technology

[0004] Most of the existing draw-out switchgears are drawers neatly arranged horizontally and vertically. When technicians are performing maintenance, it is more troublesome to take out the drawers with a higher height. Afterwards, it is easy to overturn. At the same time, when the existing neatly arranged drawers dissipate heat, the air circulation mostly passes through the gaps. In order to meet the heat dissipation requirements, a high-power fan is often required.

Embodiment 1

[0027] Example 1: Please refer to image 3 , a draw-out low-voltage switchgear, including a box body 1. In this embodiment, the box body 1 is cylindrical or prismatic, which is convenient for evenly distributing the drawers 27. There is a circle on the side wall of the box body 1. There are several distributed first heat dissipation holes 2, and the end surface of one side of the box body 1 is an open structure, and the first heat dissipation holes 2 are used to dissipate the heat in the box body 1 to the outside;

[0028] see Figure 4-6 , the rotating bracket 3 includes a support plate 4, the support plate 4 is a circular plate, the outer side of the support plate 4 is provided with a circumferential groove 5, the opening side of the box body 1 is provided with a mounting groove 6, and the mounting groove 6 is rotationally connected with a support wheel 7 , there are several support wheels 7 distributed around the circumference of the box body 1, and the rotating bracket 3 ...

Embodiment 2

[0041] Example 2: Please refer to Figure 8 , in this embodiment, the electrical connection bracket includes a rod frame 22 and a mounting plate 23, the rod frame 22 is rotatably connected to the delivery pipe 16, the rod frame 22 is located between the fan 20 and the air hole 18, and the mounting plate 23 is fixed on the rod On the frame 22 away from the end of the conveying pipe 16, there are two socket seats 21 symmetrically arranged on the mounting plate 23. Similarly, there are two symmetrically arranged socket ports 13 on the drawer 27. When the socket socket 13 is plugged into the corresponding socket seat 21 When connected electrically, realize the input and output of the electrical signal of the electric element in the drawer 27.

Embodiment 3

[0042] Example 3: Please refer to figure 1, in this embodiment, the limit block is fixed on the side of the box body 1, and the base 26 is provided with a card slot. It is provided with a rotating bracket 3 and a heat dissipation structure, and the box body 1 is detachably fixed on the base 26, which is convenient for installation and disassembly operations;

[0043] The working principle of the present invention is: when the switchgear is in normal use, the fan 20 blows gas into the delivery pipe 16, and the air flow is ejected from the air holes 18 on the delivery pipe 16. A special position ensures that the airflow is in efficient contact with the drawer 27 as a whole. The airflow enters the interior through the second heat dissipation hole 12, takes away the heat, and then discharges it from the first heat dissipation hole 2 on the box body 1; When the internal electrical components are inspected and repaired, the auxiliary handle 25 on the outside of the support plate 4 ...

Abstract

The invention discloses a draw-out type low-voltage switch cabinet, and relates to the technical field of switch cabinets. The switch cabinet comprises a box body, a rotary bracket and a heat dissipation structure; and the rotating bracket is rotationally connected to the inner opening side of the box body, the heat dissipation structure is fixed to the face, opposite to the inner opening side, of the box body, and a plurality of drawers are arranged on the rotating bracket. Compared with the prior art, the switch cabinet has the beneficial effects that: the drawers are fixed on the rotary bracket, and the rotary bracket is rotationally connected in the box body, so that for the switch cabinet, a so-called drawer positioned at a high position does not exist, when a technician needs to overhaul and check a certain drawer, the technician only needs to rotate the rotary bracket, the corresponding drawer is rotated to the lower part, the objects can be taken out, and some error operations during taking the objects at a high place are avoided.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a withdrawable low-voltage switch cabinet. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. [0003] The withdrawable switchgear is a closed shell made of steel plate, and the electrical components of the incoming and outgoing circuit are installed in the drawer, which constitutes a functional unit that can complete a certain type of power supply task. Compared with the traditional switchgear, this kind of switchgear is operated It is more flexible, and it is more convenient to repair and maintain in normal times. [0004] Most of the existing draw-out switchgears are drawers neatly arranged horizontally and vertically. When technicians are performing maintenance, it is more troublesom...
