Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, and more specifically, to a photovoltaic power generation control cabinet. Background Art

[0002] Photovoltaic AC and DC control cabinets refer to photovoltaic AC control cabinets and photovoltaic DC control cabinets. Photovoltaic DC control cabinets are mainly used in large-scale photovoltaic power stations to connect busbar boxes and photovoltaic inverters, and provide lightning protection and overcurrent protection, monitor the single-string current, voltage of the photovoltaic array, and the status of lightning arresters and circuit breakers. Professional electrical design and component selection can ensure long-term stable operation. Therefore, in order to better ensure the use effect of the photovoltaic power generation control cabinet, a photovoltaic power generation control cabinet is needed.

[0003] During the use of the existing photovoltaic power generation control cabinet, only the inside of the control cabinet can be cooled. As a result, the cooling effect is not good. Since most of the casings of the control cabinets are made of some metal materials with certain conductivity, part of the heat will enter the inside of the cabinet. When the existing photovoltaic power generation control cabinet allows air to enter the inside of the cabinet, the incoming air is not subjected to static electricity removal treatment, which affects the use effect of the control cabinet.

And a part of the second processing component 3 is arranged outside the cabinet body 1. A controller 4 is installed inside the cabinet body 1, and a clamping seat 7 is arranged inside the cabinet body 1. A placement plate 8 is connected to two of the clamping seats 7.

[0027] As Figure 1 - Figure 8 As shown in the figure, the first processing component 2 includes sixteen conveying grooves 201 with a U-shaped cross-section. The conveying grooves 201 are opened at one end of the cabinet body 1. One end of the conveying groove 201 is connected to a first shunt pipe 202. One end of the first shunt pipe 202 is connected to a first mounting cover 203. A plurality of input covers 204 and a filter drying net 205 are arranged inside the first mounting cover 203 for filtering and drying impurities and water molecules in the gas. An input fan 206 is arranged inside the input cover 204. The other end of the conveying groove 201 is connected to a second shunt pipe 207. One end of the second shunt pipe 207 is connected to a second mounting cover 208. A plurality of output holes 209 in a frustum shape are opened inside the cabinet body 1, and the output holes 209 are communicated with the conveying grooves 201. A plurality of output covers 210 are installed inside the second mounting cover 208. An output fan 211 is arranged inside the output cover 210. Temperature sensors 5 and humidity sensors 6 are symmetrically arranged inside the cabinet body 1.

[0028] As Figure 1 - Figure 8 As shown in the figure, the second processing component 3 includes a first motor 301. The first motor 301 is arranged at one end of the cabinet body 1. The output shaft of the first motor 301 is provided with a first threaded rod 302 through a coupling.

An electrostatic eliminator 304 is connected to the first threaded rod 302 and the first guide rod 303. The principle of the electrostatic eliminator 304 is the same as that of the model PG-502A;

[0029] The second processing component 3 further includes a second motor 305. The second motor 305 is arranged at one end of the cabinet body 1 through a support frame. The output shaft of the second motor 305 is connected with a second threaded rod 306 through a coupling.

Then, the output fan 211 is started through the controller 4. Then, the output fan 211 generates suction and inhales the heat generated by the electrical equipment inside the cabinet body 1 into the conveying groove 201 through the output hole 209, and then it is transported into the second shunt pipe 207 together with the gas for shell heat dissipation, and then it is discharged through the output cover 210, so as to dissipate heat from the shell of the cabinet body 1 and the inside of the cabinet body 1 at the same time, and further ensure the use effect of the control cabinet better.

[0031] When the heat inside the cabinet body 1 is discharged, the first motor 301 and the static eliminator 304 are started through the controller 4. Then, the output shaft of the first motor 301 drives the first threaded rod 302 to rotate, and then the static eliminator 304 is driven to move up and down in cooperation with the first guide rod 303, so as to eliminate the static electricity inside the cabinet body 1, and thus ensure the use effect of the cabinet body 1. Then, the second motor 305, the thermometer 309 and the current transformer 310 are started through the controller 4. Then, the output shaft of the second motor 305 drives the second threaded rod 306 to rotate, and then the second threaded rod 306 and the second guide rod 308 cooperate with each other to drive the moving cover 307, so as to detect the temperature outside the cabinet body 1 and whether there is a leakage problem in the shell of the cabinet body 1, and thus better discover the problems existing in the cabinet body 1.
