Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

As shown in fig. 1 and 2, this embodiment provides a high-voltage capacitance compensation cabinet, which includes a cabinet body 1, a high-voltage reactor 2, a high-voltage transformer 3, a high-voltage capacitor 4, a high-voltage isolating switch 5, a zinc oxide arrester 6, and a high-voltage insulator 7. Wherein, the middle part in the cabinet body 1 is provided with a vertical clapboard 11 to divide the space in the cabinet body 1 into a first cavity on the left side and a second cavity 102 on the right side; and a transverse partition 12 is provided in the upper middle portion of the first chamber to divide the first chamber into an upper first upper chamber 1011 and a lower first lower chamber 1012. The high-voltage reactor 2 is arranged on the bottom plate of the first lower cavity 1012; the high-voltage transformer 3 is arranged on the transverse partition plate 12; the high-voltage capacitor 4 is provided with three rows and is arranged at the lower, middle and upper three parts in the second cavity 102 at intervals through a bracket; the high-voltage isolating switch 5 is arranged on the side wall of the first upper cavity 1011 and is electrically connected with the high-voltage reactor 2; the zinc oxide lightning arrester 6 is arranged at the top of the first upper cavity 1011, and the plurality of high-voltage insulators 7 are respectively arranged at the top of the first upper cavity 1011, the vertical partition 11 and the top of the second cavity 102 so as to connect the lead wires of the zinc oxide lightning arrester 6 to corresponding parts. So, whole cabinet body 1 is separated into three parts to set up high-voltage reactor 2, high-voltage transformer 3 and high-voltage capacitor 4 in order, avoid interfering each other and influence, also the maintenance operation of being convenient for.

In order to ensure that three parts in the whole cabinet body can effectively dissipate heat, too many fans are avoided, a ventilation and heat dissipation path sequentially passing through the three parts is designed according to the position relation of three cavities in the cabinet body, and the ventilation and heat dissipation path can sequentially pass through a first lower cavity 1012, a second cavity 102 and a first upper cavity 1011 in consideration of the rising principle of hot air, so that an air inlet 13 is required to be formed in the side wall of the first lower cavity 1012, an air outlet 14 is formed in the side wall of the first upper cavity 1011, a ventilation opening is formed between the first lower cavity 1012 and the second cavity 102, and a ventilation opening is also formed between the second cavity 102 and the first upper cavity 1011. Then, the fan 8 may be disposed at any one of the four air openings, but since the two air openings are disposed on the vertical partition 11, if the fan 8 is disposed at the air inlet 13, the air outlet 14 or the air opening at the upper portion, the air flow passing through the second cavity 102 is mainly concentrated near the vertical partition 11, and the second cavity 102 cannot be effectively cooled. Therefore, as shown in fig. 3, the most preferred embodiment is that the fan 8 is disposed between the first lower chamber 1012 and the second chamber 102, and the ventilation opening between the first upper chamber 1011 and the second chamber 102 is used as the air guiding opening 15, that is, the fan 8 blows air from the first lower chamber 1012 into the second chamber 102, and the air just blown by the fan 8 has a larger power and can be blown to the right side in the second chamber 102 shown in fig. 1, thereby effectively causing the air flow in the whole second chamber and ensuring the heat dissipation effect.

Specifically, as shown in fig. 2 and 3, in order to ensure that the flowing air can drive the air flowing through the entire first lower cavity 1012 as much as possible, the fan 8 may be disposed on a side of the vertical partition 11 away from the air inlet 13, for example, in this embodiment, the air inlet 13 is disposed on the left side of the cabinet door, and the fan 8 is disposed on a side of the vertical partition 11 near the back of the cabinet body, so that the air flow obliquely passes through the first lower cavity 1012 to drive the air to flow for effective heat dissipation; of course, the air inlet 13 may be disposed at the left side of the back of the cabinet, and the fan 8 may be disposed at one side of the vertical partition 11 close to the cabinet door. Accordingly, as shown in fig. 3, in order to ensure the air flowability in the second cavity 102, the air guide opening 15 and the fan 8 may be respectively disposed at the positions of the vertical partition 11 near the opposite sides of the cabinet, for example, in this embodiment, since the fan 8 is disposed on the side of the vertical partition 11 near the back of the cabinet, the air guide opening 15 needs to be disposed on the side of the vertical partition 11 near the cabinet door, so that the air flow can obliquely pass through the second cavity from bottom to top to drive the air flow to perform effective heat dissipation. Similarly, as shown in fig. 1 and 3, in order to ensure air flowability in the first upper cavity 1011, the air guide 15 may be disposed on a side of the vertical partition 11 away from the air outlet 14, for example, in this embodiment, since the air guide 15 is disposed on a side of the vertical partition 11 close to the cabinet door, the air outlet 14 needs to be disposed on the left side of the back of the cabinet.

In addition, as shown in fig. 3, the fan 8 is disposed at the lower portion of the vertical partition 11, so that the air flow into the second chamber 102 is at the lowest position, and the air fluidity in the second chamber can be ensured. Similarly, the air guide opening 15 is disposed at the position of the vertical partition 11 near the transverse partition 12, so that the air flow entering the first upper cavity 1011 is at the lowest position, and the air flow in the first upper cavity is effectively driven to flow. The first lower cavity 1012 is directly air-inlet by the air inlet, so that the air inlet area is large, and the fluidity of air is ensured.

Since the fan needs to operate for a long time, the fan is likely to be out of order, and thus the efficiency of the disassembly, assembly and maintenance of the fan is important. For this purpose, as shown in fig. 4, the fan 8 includes a main body 81, fixing limiting plates 82 and mounting limiting plates 83 disposed at edges of two ends of the main body 81, the main body 81 is embedded in the vertical partition 11, and the fixing limiting plates 82 and the mounting limiting plates 83 respectively abut against two side surfaces of the vertical partition 11. The middle part of the installation limiting plate 83 is provided with a through hole, an installation sleeve 831 is arranged at the edge of the through hole, the installation sleeve 831 is provided with an internal thread, and the main body part 81 is provided with an external thread 811. During installation, the threaded end of the main body 81 passes through the ventilation opening of the vertical partition 11 until the fixed limiting plate 82 at the end part of the threaded end abuts against the side surface of the vertical partition 11, then the installation limiting plate 83 is tightly screwed by the threaded fit of the installation sleeve 831 and the main body 81 to abut against the other side surface of the vertical partition 11, and at the moment, the fan 8 is tightly held on the vertical partition 11 through the fixed limiting plate 82 and the installation limiting plate 83; when the detachable limiting plate is detached, the limiting plate is only required to be screwed down, and the detachable limiting plate is convenient to detach and maintain. And in order to facilitate the rotation operation of the mounting sleeve, an anti-slip strip 832 is provided on the outer side of the mounting sleeve 831.
