Description

Technical Field

[0002] A box-type substation is a factory-prefabricated indoor and outdoor compact distribution equipment that is composed of high-voltage switchgear, distribution transformers and low-voltage distribution devices arranged in an integrated manner according to a certain wiring scheme. A box-type substation will generate a relatively high temperature during operation, so it is necessary to perform heat dissipation and cooling treatment. A Chinese patent with publication number "CN113097873B" provides a box-type substation heat dissipation system. The application sets a heat dissipation zone so that a fan in the heat dissipation zone introduces outside air into the frame and takes out the heat inside the cabinet, thereby achieving the effect of cooling and heat dissipation. However, when the external ambient temperature is high, the cooling and heat dissipation effect is poor, and the heat dissipation zone is provided with structures such as electrical components, which occupy a large amount of space in the box-type substation. At the same time, the existing box-type substation is generally divided into two chambers. The application cannot perform centralized and rapid heat dissipation of the chamber with a higher temperature, so that the chamber is still at a relatively high temperature.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] See also Figures 1 to 6 The present invention provides a box-type substation with a heat dissipation device, comprising a box body 1, wherein the box body 1 is provided with two chambers, a first partition plate 2 for separating the two chambers is fixedly connected inside the box body 1, a mounting groove 3 is opened on the first partition plate 2, a distribution mechanism 4 for controlling the passage of gas is fixedly connected inside the mounting groove 3, a refrigeration mechanism 5 for refrigeration is fixedly connected to the outer wall of the box body 1, the output end of the refrigeration mechanism 5 is connected to the distribution mechanism 4, the output ends of the distribution mechanism 4 respectively located in the two chambers are fixedly connected with a cooling mechanism 6, and the cooling mechanism 6 is coated on the electrical components in the two chambers.

[0024] The refrigeration mechanism 5 is provided to produce low-temperature air, and flows to the cooling mechanism 6 located in the two chambers of the box body 1 through the distribution mechanism 4. In the initial state, the distribution mechanism 4 evenly distributes the low-temperature air to the cooling mechanism 6 in the two chambers, so as to dissipate the heat of the electrical components in the two chambers, and the cooling mechanism 6 is wrapped around the electrical components in the two chambers, which will not occupy too much space in the box-type substation. It can be retrofitted and modified on the original box-type substation to reduce the corresponding production time. The distribution mechanism 4 can redistribute the low-temperature air when the temperature of one chamber is higher than that of the other chamber, and more low-temperature air is transported to the high-temperature chamber to dissipate heat faster.

[0025] See also Figure 3 and Figure 4The distribution mechanism 4 includes a fixed tube 7 fixedly connected to the mounting groove 3, one end of the fixed tube 7 is fixedly connected to a distribution tube 8, both ends of the distribution tube 8 pass through the first partition plate 2 and extend into the chamber, the position where the distribution tube 8 is connected to the fixed tube 7 is rotatably connected to a first rotating shaft 9, one end of the first rotating shaft 9 extending into the distribution tube 8 is fixedly connected to a partition block 10, the position of the fixed tube 7 close to the partition block 10 is symmetrically fixedly connected to a limiting block 11, one end of the first rotating shaft 9 extending outside the distribution tube 8 is fixedly connected to a connecting rod 12, and the end of the connecting rod 12 away from the first rotating shaft 9 is fixedly connected to a pushing rod 13, and one side of the first partition plate 2 located in the two chambers is fixedly connected to a driving assembly 14, and the driving assembly 14 is used to drive the pushing rod 13 to move.

[0026] Please refer to the figure Figure 4 and Figure 5 The driving component 14 includes a mounting frame 15 fixedly connected to the first partition plate 2, a sliding groove 16 is provided on the mounting frame 15 near the first partition plate 2, an airbag 17 is provided inside the mounting frame 15, an end of the airbag 17 near the push rod 13 is fixedly connected to a sliding plate 18, an end of the sliding plate 18 away from the airbag 17 is fixedly connected to an abutment rod 19, and an end of the sliding plate 18 located in the sliding groove 16 is fixedly connected to a limiting plate 20.

[0027] When the temperature of one of the chambers is relatively high, the airbag 17 in the chamber will expand to a larger volume, and the airbag 17 will drive the sliding plate 18 to move. The movement of the sliding plate 18 drives the abutment rod 19 to move. The movement of the abutment rod 19 drives the push rod 13 to rotate around the first rotating shaft 9. The rotation of the push rod 13 drives the first rotating shaft 9 to rotate. The rotation of the first rotating shaft 9 drives the partition block 10 to rotate. The partition block 10 rotates away from the chamber with a relatively high temperature, so that the space connected to the fixed pipe 7 and the distribution pipe 8 on the side of the chamber with a relatively high temperature is increased, so that more low-temperature air can flow to the chamber with a higher temperature, thereby quickly dissipating the heat of the electrical components therein and preventing damage caused by the continuous increase in the temperature of the electrical components. When the partition block 10 rotates, the limit block 11 limits the partition block 10 to prevent the partition block 10 from completely closing the partition block 10 on the side of the chamber with a lower temperature, thereby preventing the electrical components in the chamber with a lower temperature from being unable to dissipate heat, causing the temperature of the electrical components in the chamber to continue to rise.

[0028] See also Figure 1 , Figure 5 and Figure 6The cooling mechanism 6 includes a connecting sleeve 21 fixedly connected to the distribution pipe 8, and the end of the connecting sleeve 21 away from the distribution pipe 8 is fixedly connected to a cooling pipe 22, and the cooling pipe 22 is fixedly connected to a second partition plate 23 along the axial direction. A second rotating shaft 24 is rotatably connected through the connecting sleeve 21, and one end of the second rotating shaft 24 located in the connecting sleeve 21 is fixedly connected to a blocking block 25, and one end of the second rotating shaft 24 extending into the installation frame 15 is fixedly connected to a pushing block 26. A torsion spring 27 is sleeved on the second rotating shaft 24, and one end of the torsion spring 27 is fixedly connected to the connecting sleeve 21, and the other end of the torsion spring 27 is fixedly connected to the second rotating shaft 24.

[0029] In the initial state, under the action of the torsion spring 27, the blocking block 25 is in a position parallel to the axis of the connecting sleeve 21. When the temperature of one of the chambers rises to a certain height, the airbag 17 will expand, driving the sliding plate 18 to move. The movement of the sliding plate 18 drives the limit plate 20 to move. The limit plate 20 moves and abuts against the push block 26. When the limit plate 20 continues to move, the push block 26 will overcome the force of the torsion spring 27 and rotate. The rotation of the push block 26 drives the second rotating shaft 24 to rotate. The rotation of the second rotating shaft 24 drives the blocking block 25 to rotate. The rotation of the blocking block 25 will close half of the cavity of the cooling tube 22, so that the low-temperature gas flowing into the cooling tube 22 can produce a faster flow speed, and the heat exchange speed with the electrical components in the chamber is increased, so that the temperature of the electrical components in the chamber with relatively high temperature can be reduced more quickly.

[0030] See also Figure 1 and Figure 6 The cooling tube 22 is wrapped around the electrical components in the two chambers. The cooling tube 22 is divided into two channels by the second partition plate 23. When the barrier block 25 closes one of the channels, the flow rate of the low-temperature gas in the other channel is accelerated, and the heat exchange rate with the electrical components is accelerated, thereby transferring the heat from the electrical components faster and completing the rapid heat dissipation process.

[0031] See also Figure 6 The blocking block 25 is semicircular and is used to close one of the channels of the cooling pipe 22. The semicircular blocking block 25 can only close one of the channels of the cooling pipe 22 when rotating, thereby increasing the flow rate of the low-temperature gas flowing in the cooling pipe 22.

[0032] See also Figure 5 and Figure 6 The side of the pushing block 26 close to the sliding plate 18 is arc-shaped, the pushing block 26 abuts against the limiting plate 20, and the side of the pushing block 26 in contact with the sliding plate 18 is arc-shaped, so as to avoid the limiting plate 20 being stuck in the sliding groove 16 by abutting against one side of the pushing block 26 when the limiting plate 20 returns.

[0033] See also Figure 4 The abutting rod 19 is hinged to the pushing rod 13 , and the movement of the abutting rod 19 can drive the pushing rod 13 to rotate around the first rotating shaft 9 .

[0034] See also Figure 2 and Figure 3 One end of the fixed pipe 7 extending outside the box body 1 is connected to the refrigeration mechanism 5, so that the low-temperature gas generated by the refrigeration mechanism 5 is distributed through the fixed pipe 7 and flows into the cooling pipes 22 in the two chambers.

[0035] See also Figure 1 A storage chamber 28 is provided at the lower side of the box body 1, and a sponge is provided in the storage chamber 28. The storage chamber 28 is connected to the end of the cooling tube 22 away from the connecting sleeve 21. The sponge can absorb moisture. The air in the end of the cooling tube 22 away from the connecting sleeve 21 completes heat exchange with the electrical components. The air temperature there is relatively high, so that the air temperature entering the storage chamber 28 is higher, so that the sponge that absorbs moisture can dry faster and absorb moisture again to maintain a dry environment in the box body 1.
