Description

[0002] A capacitor compensation cabinet is a device and apparatus that generates reactive power where reactive power is required in order to improve the energy waste caused by low power factor of the power grid and these factors that are unfavorable to power supply production, that is, to increase reactive power compensation. The inside of the capacitor compensation cabinet mainly consists of busbars, fuses, disconnector fuse sets, capacitor contactors,..., power factor automatic compensation control devices, etc. Since there are a large number of components loaded in the cabinet and the operating power is high, a fan group is often set inside the cabinet for ventilation and heat dissipation. However, at present, mainly two fans are set at the middle positions on both sides inside the cabinet, and the air flow direction of the fans is mostly straight. For the bottom area and the top area inside the cabinet, most of the flowing air cannot flow well to this area. When the bottom area or the top area has high heat, the air flow concentrated in the middle area cannot be cooled in time. Therefore, those skilled in the art propose a ventilation component for a capacitor compensation cabinet and a cabinet body of a capacitor compensation cabinet here. Content of the Utility Model

[0027] Refer to the attached specificationFigure 4 As shown in the figure; the bellows mechanism 23 includes a rectangular frame 231 fixed to the inner port of the air inlet and outlet grille 22, two air cylinders 237 fixed in the inner cavity of the rectangular frame 231, and a servo motor 232 fixed inside the air cylinder 237. The output shaft of the servo motor 232 is fixedly connected with 5-8 fan blades 233 through a coupling. Among them, a strip frame 234 is fixed in the inner cavity of the rectangular frame 231. Servo cylinders 236 are fixed on the upper and lower surfaces of the inner cavity of the strip frame 234. And a turning plate 235 is rotatably connected to the left and right side walls of the inner cavity of the strip frame 234. The telescopic shaft of the servo cylinder 236 is hinged to the surface of the turning plate 235 away from each other.

[0028] Refer to the attached instruction manual Figure 4 As shown in the figure; connecting members 238 are fixedly connected to the surfaces of the air cylinders 237 away from each other and the upper and lower surfaces. And the end of the connecting member 238 away from the air cylinder 237 is fixedly connected to the side wall of the inner cavity of the rectangular frame 231.

And the end of the hinge away from the turning plate 235 is fixedly connected to the end of the telescopic shaft of the servo cylinder 236.

[0030] Refer to the attached instruction manual Figure 2 As shown in the figure; for the capacitor compensation cabinet body, specifically, there is a cabinet body 11, a metal frame 13 fixed in the inner cavity of the cabinet body 11, and electrical components 12 fixedly locked to the front surface of the metal frame 13 by screws.

For example, if the turning plate 235 on the right is inclined downward, the turning plate 235 on the left is also inclined downward, making the air flow direction inside the cabinet body 11 present a "V" shape, so as to dissipate heat from the area with too high temperature in time and draw away the hot air after heat exchange in time.
