Description

Technical Field

[0001] The invention relates to the technical field of bus ducts, and in particular to an energy-saving bus duct with a high-efficiency waterproof function. Background Art

[0002] In order to meet the needs of high-current low-voltage transmission lines in industrial and civil engineering construction, the power distribution design adopts the bus duct trunk system. In recent years, with the continuous increase in the capacity of transmission and distribution lines, the bus duct trunk system has been widely used in engineering. The bus duct product structure design has changed from air insulation type to dense insulation type, from steel plate shell to aluminum alloy shell, from flat structure shell to heat dissipation strip structure shell, and the protection level has changed from IP40 to IP66, which runs through the development process of the entire industry. The most important technical performance index of the bus duct is the line loss caused by the conductor temperature rise and the reactance of electromagnetic induction. Current generates heat energy due to resistance. Since the bus duct is a high-current transmission line with concentrated conductors, the thermal effect of the conductor due to resistance is also particularly concentrated. The heat dissipation effect of the bus duct shell is directly related to the technical performance index of the entire product, the manufacturing and investment costs of the enterprise, and the safe use of users. In the past, the air-insulated bus duct with steel plate-formed shell used in the market had poor heat dissipation. The cross-sectional area of ​​its conductor was generally larger than that of the densely insulated bus duct conductor, and the temperature rise of the conductor was also higher than that of the densely insulated bus duct conductor. It was the most uneconomical product. This product will gradually be replaced by densely insulated bus duct products. In order to improve the heat dissipation performance of densely insulated bus duct, foreign countries have developed densely insulated bus duct products with aluminum alloy shells and heat dissipation strips. However, the existing energy-saving bus duct has a simple structure and poor heat dissipation effect inside the duct body, which causes energy loss in the bus duct and reduces the performance of the device. Moreover, at present, conventional busbar ends generally only have a circle of EVA sealing strip wrapped around the copper bar end, without an effective sealing design, and the sealing strip is easy to fall off. The protection of this part is weak, and water ingress short-circuit failure is prone to occur, which will affect the overall use. For this reason, there is a public technology that proposes a low-carbon, energy-saving and waterproof busbar duct, its matching end, connector and connection method. The low-carbon, energy-saving and waterproof busbar duct includes a busbar duct body formed by two busbar cover plates and two busbar side plates. A plurality of heat sinks are arranged on the outer side of the busbar side plate, and the heat sinks are arranged on the busbar side plate to form a protruding serrated shape. A plurality of heat sink teeth are arranged on the surface of the heat sink, and the heat sink teeth are evenly arranged on the heat sink to form a wave shape. The wavy heat sink teeth increase the heat dissipation area, and the cross-section of the heat sink teeth is an arc-shaped convex shape. After the bus duct is connected, a protective plate is installed on the side of the connector, and a sealing gasket is attached to the inside of the connection cover to ensure that the protection level of the connector is consistent with that of the bus body. The protection level of the connector can reach IP66. However, only by setting a sealing gasket at the connection, the waterproof effect of the energy-saving bus duct proposed in the disclosed technology is still insufficient.

[0003] There is also a disclosed technology that proposes a waterproof busbar duct device, including a first side plate, a second side plate, a top plate and a bottom plate, both ends of the first side plate and the second side plate are provided with a card slot, the top plate and the bottom plate are arranged in parallel, and the two ends are inserted into the card slots at the ends of the first side plate and the second side plate, and the device also includes: an inner sealing box, the inner sealing box is fixed on the bottom plate, the busbar is fixed in the inner sealing box, and the inner sealing box is filled with sealing material; a locking mechanism, the locking mechanism is installed on the top plate and the bottom plate; a heat dissipation mechanism. The present invention forms a cavity by enclosing the first side plate, the second side plate, the top plate and the bottom plate to form a first sealing layer, and an inner sealing box is arranged therein, and the double-layer sealing improves the waterproof performance, and because the first side plate, the second side plate, the top plate and the bottom plate are an enclosed structure, they can be easily repaired and replaced. Compared with the aforementioned disclosed technology, the disclosed technology proposes a double-layer sealing structure, which further improves the waterproof effect compared with the single-layer sealing.

[0004] However, the waterproofing measures for energy-saving bus ducts should be carried out simultaneously from the three aspects of drainage, sealing and waterproofing effect detection, rather than just considering the sealing problem at the connection. For this reason, it is necessary to further improve and optimize the waterproofing structure of the energy-saving bus duct. Summary of the invention

[0018] (III) Beneficial effects

[0019] The present invention provides an energy-saving bus duct with high-efficiency waterproof function. It has the following beneficial effects:

[0020] 1. Compared with the prior art, the energy-saving bus duct with high-efficiency waterproof function has water holes penetrating up and down on the inner wall of the upper cover, and multiple groups of water retaining blocks are arranged on the opposite sides of the two groups of side panels. When used outdoors or through walls, the water falling in the groove of the upper cover will be discharged downward through the water holes, and the water falling on the sides in the length direction will be intercepted by the multiple groups of water retaining blocks and drip down along the water retaining blocks. When there is a height difference between the front and back of the bus duct during installation, most of the water will be intercepted by the water retaining blocks and discharged through the water holes, and the end located at the low place will not be soaked by a large amount of water. By intercepting and guiding the water flow, the risk of water ingress inside the energy-saving bus duct is effectively reduced, and the waterproof effect is improved.

[0021] 2. Compared with the prior art, the energy-saving bus duct with efficient waterproof function is provided with side sealing strips between the side plate and the upper cover and between the side plate and the lower cover, and the end of the shell is provided with an end face seal. When the assembly is completed, the side plate and the upper cover and between the side plate and the lower cover are tightened by rivets, and the side sealing strips are squeezed to fully seal the connection between the side plate and the upper cover and between the side plate and the lower cover. The protective cover is fixedly connected to the fixing block and the shell by the second screw. After locking, the protective cover squeezes the end face seal to fill it between the inner wall of the shell and the outer wall of the conductive row, and seals the end of the shell and the outer wall of the conductive row. The waterproof effect is further improved by the side sealing strips and the end face seals.

[0022] 3. Compared with the prior art, the energy-saving bus duct with high-efficiency waterproof function has three sets of waterstop plates made of water-swelling rubber inside the shell and between the end face seal and the composite resin casting body to avoid aging and failure of the end face seal during long-term use. The three sets of waterstop plates supplement the sealing effect of the end face seal. Once the end face seal ages and fails, water encounters the waterstop plate and expands rapidly due to the characteristics of the water-swelling rubber, filling the space between the shell and the conductive bar, and cooperates with the end face seal to achieve a double-layer sealing effect on the end face.

[0023] 4. Compared with the prior art, this energy-saving bus duct with efficient waterproof function, in order to avoid aging and failure of the side sealing strips during long-term use, has receiving grooves arranged on the four walls of the composite resin casting body except for the two ends in the length direction, and the receiving grooves are filled with renewable desiccant. The desiccant absorbs water entering from the side, and cooperates with the side sealing strips to achieve a double-layer sealing effect on the side.

[0024] 5. Compared with the existing technology, the energy-saving bus duct with efficient waterproof function is also equipped with multiple groups of humidity detection probes in the receiving slot to detect the humidity conditions inside the shell, and transmit the humidity detection signal to the control box through a wire. The humidity conditions are fed back to the management platform through the communication module and communication antenna in the control box to avoid malfunctions caused by continued use of the bus duct after the waterproof measures fail, thereby achieving the effect of unmanned management.

The lower cover 1, the upper cover 3 and the two groups of side panels 2 are fixedly connected by multiple groups of rivets 5. The groove 4 is arranged on the upper wall of the upper cover 3. The outer wall of the shell can also be provided with a heat dissipation device proposed in the existing public technology to improve its energy-saving effect. This embodiment specifically improves the waterproof effect of the energy-saving bus duct, so the heat dissipation part is not described in detail;

[0036] like Figure 1 , Figure 3 As shown, in order to protect the conductive bar 10, multiple groups of conductive bars 10 are wrapped by a composite resin casting body 22, the composite resin casting body 22 is located inside the shell, the front end of the conductive bar 10 passes through the front wall of the composite resin casting body 22 and extends into the protective cover 9, and the outer wall of the conductive bar 10 is provided with a protective coating 11, which covers the rest of the conductive bar 10 except the two ends in the length direction. The protective coating 11 plays the role of insulation, corrosion resistance and moisture resistance, and fully protects the conductive bar 10;

[0037] like Figure 1 , Figure 3 as well as Figure 4 As shown, in order to seal and protect the end face of the shell, the shell has an upper wall provided with a groove 4, the inner wall of the groove 4 is fixedly connected with a fixing block 8 near the front end of the shell, the protective cover 9 is fixedly connected to the front end of the shell and the front wall of the fixing block 8 through multiple sets of second screws 13, and an end face sealing structure for sealing the front end of the shell is provided between the protective cover 9 and the composite resin casting body 22, and the end face sealing structure is an end face sealing member 18, which is arranged on the inner side wall of the shell and is located between the protective cover 9 and the water-stop structure, and the outer walls of multiple sets of conductive bars 10 all penetrate the inner wall of the end face sealing member 18, and the front end of the shell is sealed and waterproofed by the end face sealing member 18, and when the protective cover 9 is fixedly connected to the front end of the shell and the front wall of the fixing block 8 through multiple sets of second screws 13, the end face sealing member 18 is squeezed to fill between the conductive bar 10 and the inner side wall of the shell, so as to play the role of end face sealing and prevent water from entering the shell from the end of the shell;

[0038] like Figure 3 , Figure 4As shown, in order to form a double-layer sealing effect on the end of the shell, a water-stop structure for improving the sealing effect at the end face is arranged between the composite resin casting body 22 and the end face sealing structure, and the water-stop structure includes a first water-stop plate 19, a second water-stop plate 20 and a third water-stop plate 21. The first water-stop plate 19, the second water-stop plate 20 and the third water-stop plate 21 are arranged in sequence from front to back inside the shell and are all located between the end face sealing structure and the composite resin casting body 22. The first water-stop plate 19, the second water-stop plate 20 and the third water-stop plate 21 are all water-absorbing and swelling rubbers. The outer walls of the plurality of conductive bars 10 are sequentially penetrated by the first water-stop plate 19. 9.

When used for a long time, the end face seal 18 may be aged and fail. In order to solve this problem, three groups of water stop plates made of water-absorbing and swelling rubber are arranged between the composite resin casting body 22 and the end face seal 18. Due to the characteristics of water-absorbing and swelling rubber, once it encounters water, it will swell and fill the space between the inner side wall of the shell and the conductive bar 10 to prevent water from continuing to enter. The three groups of water stop plates can improve the water-stopping effect and extend the service life;

[0039] like Figure 1 , Figure 7 As shown, in order to improve the sealing effect between the various joints in the shell, the joints between the upper ends of the two groups of side panels 2 and the upper cover 3 and the joints between the two groups of side panels 2 and the lower cover 1 are all provided with side sealing structures, and the side sealing structures include four groups of side sealing strips 26, which are respectively provided at the upper and lower ends of the two groups of side panels 2, and the two groups of side panels 2 and the upper cover 3 and the two groups of side panels 2 and the lower cover 1 are respectively sealed by the four groups of side sealing strips 26.

[0040] like Figure 3 , Figure 5 as well as Figure 6 As shown, in order to form a double-layer sealing effect between the various connections in the shell, a receiving groove 25 recessed toward the center of the composite resin casting body 22 is provided on the upper wall, lower wall, left wall and right wall of the composite resin casting body 22, and a water absorption structure for absorbing water is provided between the inner wall of the receiving groove 25 and the inner wall of the shell. The water absorption structure is a desiccant 23, and the desiccant 23 is filled between the inner wall of the receiving groove 25 and the inner wall of the shell. The desiccant 23 is a silicate dry gel. After long-term use, the side sealing strip 26 may be aged and failed. In order to solve this problem, the desiccant 23 is provided to absorb the water infiltrated from the various connections in the shell to prevent it from flowing out to the multiple groups of conductive bars 10 and causing short circuits;

[0041] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, in order to monitor the humidity inside the shell, a humidity detection structure for detecting the humidity inside the shell is further provided between the inner wall of the receiving groove 25 and the inner wall of the shell, and the humidity detection structure is electrically connected to the control box 14 through a wire. The humidity detection structure includes multiple groups of humidity detection probes 24, which are arranged on the inner wall of the receiving groove 25 in a front-to-back distribution, and are electrically connected to the control box 14 through a wire. The control box 14 is arranged on the upper wall of the fixed block 8, and the upper wall of the control box 14 is arranged with a display screen 15 and a speaker 16 in a front-to-back distribution, and a communication antenna 17 is arranged on the front wall of the control box 14. The humidity detection probe 24 is used to detect the humidity inside the shell, and the internal main board of the control box 14 can adopt a low-power chip.

When the humidity detection probe 24 detects that the humidity is greater than the set value, the humidity signal is uploaded to the management platform through the communication antenna 17 so that the engineering maintenance personnel can handle it and realize unmanned management. In addition, the speaker 16 and the display screen 15 arranged on the upper wall of the control box 14 can be used for on-site maintenance and inspection;

[0042] like Figure 1 As shown, in order to reduce the water flowing to the end of the shell when it is applied outdoors and installed through the wall, the outer wall of the shell is also provided with a side water retaining structure and a drainage structure for preventing water from flowing along the length direction of the shell. The side water retaining structure is arranged on the side opposite to the two groups of side panels 2, and the drainage structure is arranged on the inner wall of the upper cover 3. A plurality of groups of first screws 12 are arranged on the upper wall of the lower cover 1 and on the left and right sides of the two groups of side panels 2.

The plurality of groups of water retaining blocks 7 are respectively fixedly connected to the side opposite to the two groups of side panels 2 and the plurality of groups of water retaining blocks 7 on the same side are arranged in the front-to-back direction according to The water retaining block 7 is evenly spaced, and the front projection of the water retaining block 7 is in the shape of a "J", and the two ends of the "J" shape extend toward the sides of the upper cover 3 and the lower cover 1 respectively. The drainage structure is a plurality of water holes 6, and the plurality of water holes 6 are arranged in an upper and lower through-shaped manner on the inner wall of the upper cover 3 and the plurality of water holes 6 are located on the left and right sides of the two groups of side panels 2 in a top projection. The water in the groove 4 is discharged through the plurality of water holes 6 to avoid flowing to the end of the shell body. The water cup water retaining block 7 on the outer wall of the side panel 2 intercepts the water and drips downward along the extended end of the water retaining block 7 to avoid a large amount of water flowing along the outer wall of the shell to the end of the shell body, thereby improving the safety of use.

[0043] Working principle: The protective coating 11 plays the role of insulation, corrosion resistance and moisture resistance, fully protecting the conductive bar 10. When the protective cover 9 is fixedly connected to the front end of the shell and the front wall of the fixing block 8 through multiple sets of second screws 13, the end face seal 18 is squeezed to fill between the conductive bar 10 and the inner wall of the shell, playing the role of end face sealing to prevent water from entering the shell from the end of the shell. After long-term use, the end face seal 18 may age and fail. In order to solve this problem, a composite resin casting body is provided. Three sets of water-stop plates made of water-absorbing and swelling rubber are arranged between 22 and the end face seal 18. Due to the characteristics of water-absorbing and swelling rubber, once it encounters water, it will swell and fill the gap between the inner wall of the shell and the conductive row 10 to prevent water from entering further. The three sets of water-stop plates can improve the water-stop effect and extend the service life. When the rivets 5 fix the side plates 2, the upper cover 3 and the lower cover 1, the four sets of side sealing strips 26 are squeezed so that the side sealing strips 26 fill the gaps between the side plates 2 and the upper cover 3 and between the side plates 2 and the lower cover 1 to play the role of side sealing. The function of sealing is that the side sealing strip 26 may age and fail after long-term use. In order to solve this problem, a desiccant 23 is set to absorb the moisture infiltrated from the various connections in the shell to prevent it from flowing out to the multiple groups of conductive bars 10 and causing a short circuit. The humidity detection probe 24 is used to detect the humidity inside the shell. The internal main board of the control box 14 can use a low-power chip. The control box 14 is in a dormant state on a daily basis, which can greatly improve its service life. When the humidity detection probe 24 detects that the humidity is greater than the set value, the humidity signal is uploaded to the management platform through the communication module and the communication antenna 17 for processing by engineering maintenance personnel to achieve unmanned management. In addition, the speaker 16 and the display screen 15 arranged on the upper wall of the control box 14 can be used for on-site maintenance and inspection. The water in the groove 4 is discharged through multiple groups of water holes 6 to avoid flowing to the end of the shell. The water cup water retaining block 7 on the outer wall of the side panel 2 intercepts it and drips downward along the extended end of the water retaining block 7 to prevent a large amount of water from flowing along the outer wall of the shell to the end of the shell, thereby improving the safety of use.
