Description

Technical Field

[0001] The utility model relates to the technical field of transformer accessory installation, and more specifically, to an arrangement structure for facilitating the routing of secondary lines of an oil meter of a transformer capsule oil storage cabinet. Background Art

[0002] The capsule oil storage cabinet used in the existing transformer mostly adopts a one-stop installation method for the secondary line of the oil meter. This wiring has the following disadvantages: 1) Because the secondary line is a one-stop wiring, most transformer manufacturers adopt a relatively safe oil meter disassembly, packaging and transportation method, which throws the problem to the transformer after-sales installer. Due to the lack of climbing equipment on site and the oil pillow being too high, it is very unsafe to climb to the oil pillow to connect the wires; 2) When installing the secondary line on site, there is the problem of reserving the length of the secondary line. If it is too short, it is not enough; if it is too long, it is a waste and affects the appearance. At the same time, it also increases the workload of the after-sales staff and increases the after-sales cost; 3) It increases the risk caused by the after-sales staff's improper installation of the oil gauge gasket.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The following is an explanation of the embodiments of the utility model based on its overall structure.

[0027] The specific implementation of the utility model is as follows:

[0028] As attached Figure 1-Figure 6As shown, a layout structure for facilitating the routing of the secondary line of the oil meter of the transformer capsule oil conservator includes a junction box 1 and a plurality of first wire loops 2, wherein the plurality of first wire loops 2 are arranged in a row on the bottom surface of the capsule oil conservator 3, and two cabinet feet 5 supporting the capsule oil conservator 3 are provided on the transformer 4, and the junction box 1 is installed on the inner side of the cabinet foot 5 of the oil level meter 6 away from one end of the capsule oil conservator 3; the bottom surface of the capsule oil conservator 3 is provided with a plurality of first wire loops 2 arranged in a row, and a first wire passing hole 7 is opened on the top of the cabinet foot 5 close to the oil level meter 6 on the capsule oil conservator 3.

[0029] In the layout structure for facilitating the wiring of the secondary line of the oil gauge of the transformer capsule oil conservator, a junction box 1 is arranged on the cabinet foot 5 for supporting the capsule oil conservator 3. The junction box 1 has the function of wiring transfer. The internal wiring of the oil level gauge 6 can pass through the first wire hole 7 and the first wire ring 2 and then be connected to the wiring terminal at the upper end of the junction box 1, and then the secondary line can be connected to the wiring terminal at the lower end of the junction box 1.

[0030] The utility model is used to facilitate the arrangement structure of the secondary line of the oil gauge of the transformer capsule oil storage cabinet. The oil level gauge 6 is installed before the transformer is shipped, and the glass part of the oil level gauge 6 is well protected to avoid transportation damage; before shipment, the secondary line of the oil level gauge 6 is connected to the junction box 1 on the cabinet foot 5, and then the secondary line of the transformer 4 is connected to the main line slot on the transformer oil tank from the junction box 1.

[0031] This is a layout structure that facilitates the routing of the secondary line of the oil gauge of the transformer capsule oil conservator. Because the oil level gauge 6 is installed in the company, there are quality personnel to check and avoid the risk caused by the unqualified placement of the sealing ring of the oil level gauge 6;

[0032] Because the secondary line of the oil level gauge is installed in the same company as all the secondary lines of the transformers, the length of the secondary line can be guaranteed to be reasonable, making it easier to achieve neat, standardized and beautiful secondary wiring.

[0033] Since the junction box 1 is set up for transfer, the length of the secondary line is more controllable and the wiring is more convenient. There is no need to worry about the personal safety of operators when connecting the secondary line of the oil meter of the oil storage cabinet. The junction box on the market is reliable in quality and low in price. It can easily solve various problems caused by the traditional wiring method at a very low cost.

[0034] Since the oil level gauge and secondary line of the transformer oil storage cabinet are completed before delivery, the time for on-site after-sales personnel to install the transformer is reduced, reducing after-sales costs.

[0035] In this embodiment, the cabinet foot 5 includes a crossbeam 8 connected to the transformer 4, a diagonal brace column 9 provided at the end of the crossbeam 8, and a top column 10 provided at the top of the diagonal brace column 9. The crossbeam 8, the diagonal brace column 9 and the top column 10 are provided with a U-shaped groove 11 that runs through both ends, that is, the crossbeam 8, the diagonal brace column 9 and the top column 10 are channel steel structures, and the U-shaped grooves 11 in the crossbeam 8, the diagonal brace column 9 and the top column 10 are interconnected. The junction box 1 can be slidably installed in the U-shaped groove 11 of the top column 10, and the notches of the U-shaped grooves 11 on the two cabinet feet 5 are arranged facing each other. The junction box 1 is concealedly installed in the U-shaped groove 11 to avoid wind and sun exposure and ensure service life. In addition, the secondary line can also be concealed and arranged below the capsule oil storage cabinet 3 and in the U-shaped groove 11 of the cabinet foot 5. The cable routing is neat and not easy to collide with the external structure.

[0036] In this embodiment, the center line of the first wire hole 7 is coplanar with the center line of the first wire loop 2, ensuring that the secondary wire of the oil level gauge 6 can be neatly routed.

[0037] In this embodiment, a reversing roller 12 arranged above the junction box 1 is provided at the top of the U-shaped groove 11 of the top column 10. The reversing roller 12 includes a guide groove provided in the U-shaped groove 11 of the top column 10 and a V-shaped roller rotatably provided in the guide groove. The setting of the reversing roller 12 facilitates the connection of the secondary line of the oil level gauge 6 with the wiring terminal at the upper end of the junction box 1 after reversing.

[0038] In this embodiment, two vertically arranged guide rails 13 are provided in the U-shaped groove 11 of the top column 10, and a vertically extending T-shaped slide groove is provided on the guide rail 13, and a screw structure 14 capable of vertical sliding is provided in the T-shaped slide groove. Connecting plates 15 corresponding to the two guide rails 13 are provided on both sides of the junction box 1, and mounting holes adapted to the screw structure 14 are provided on the connecting plate 15. The screw structure 14 is provided with a locking nut adapted to the outer surface of the connecting plate 15, and the screw head of the screw structure 14 can slide up and down in the T-shaped slide groove, and the screw of the screw structure 14 passes through the mounting hole of the connecting plate 15 after passing through the T-shaped slide groove, and then the connecting plate 15 is fixed to the guide rail 13 by tightening the locking nut. The junction box 1 can be adjusted up and down and installed on the guide rail 13, and the tension of the secondary line of the oil level gauge 6 connected to the wiring terminal at the upper end of the junction box 1 can be adjusted to prevent the secondary line of the oil level gauge 6 from sagging and shaking easily.

[0039] In this embodiment, a second wire loop 17 is provided in the diagonal support column 9, a third guide ring 18 is provided in the crossbeam 8, and a second wire hole 19 is provided at the inner end of the crossbeam 8. The second wire loop 17 and the third guide ring 18 can guide the secondary wire of the transformer 4 connected to the terminal at the lower end of the junction box 1, so that the secondary wire of the transformer 4 is neatly arranged in the U-shaped groove 11, and is hidden in the U-shaped groove 11, which protects the lead wire.

[0040] In this embodiment, bushings are provided in the first wire passing hole 7 and the second wire passing hole 19. The bushings can prevent the lead wire from rubbing against the hole wall and causing damage to the insulating outer skin.

[0041] In this embodiment, a wire clamp 20 is provided in the U-shaped groove 11 of the crossbeam 8 at the second wire passing hole 19, and the wire clamp 20 includes two spring telescopic rods 21 relatively arranged on the upper groove wall and the lower groove wall of the U-shaped groove 11, and a pressure block 22 is provided at the telescopic end of the spring telescopic rod 21. The pressure block 22 is a rubber block structure. The wire clamp 20 can clamp the secondary wire of the transformer 4 to prevent the secondary wire of the transformer 4 from pulling on the junction box 1 when it is pulled externally.

[0042] In this embodiment, an arc groove is provided on the pressing block 22, and a rubber gasket is provided in the arc groove. The arc groove positions the secondary line to prevent the secondary line from directly sliding out of the two pressing blocks 22. The rubber gasket is provided to prevent the outer insulation skin of the secondary line from being damaged.

[0043] Working principle:

[0044] Before the transformer is shipped, the oil level gauge 6 is installed and the glass part of the oil level gauge 6 is well protected. Then, the secondary wire of the oil level gauge 6 is extended to the bottom of the capsule oil storage cabinet 3 through the first wire hole 7, and then through the first wire ring 2, and then the reversing roller 12 is turned down to connect to the terminal at the upper end of the junction box 1, and then the secondary wire of the transformer 4 is passed through the second wire hole 19 into the U-shaped groove 11 of the beam 8, and then through the second guide ring 17 and the third guide ring 18. Connect to the terminal at the lower end of the junction box 1; then clamp the secondary wire of the transformer 4 with the wire clamp 20.

[0045] This is a layout structure that facilitates the routing of the secondary line of the oil gauge of the transformer capsule oil conservator. Because the oil level gauge 6 is installed in the company, there are quality personnel to check and avoid the risk caused by the unqualified placement of the sealing ring of the oil level gauge 6;

[0046] Because the secondary line of the oil level gauge is installed in the same company as all the secondary lines of the transformers, the length of the secondary line can be guaranteed to be reasonable, making it easier to achieve neat, standardized and beautiful secondary wiring.

[0047] Since the junction box 1 is set up for transfer, the length of the secondary line is more controllable and the wiring is more convenient. There is no need to worry about the personal safety of operators when connecting the secondary line of the oil gauge of the oil storage cabinet, which saves time for on-site installation of the oil level gauge and the secondary line. The junction box on the market is of reliable quality and low price, and can easily solve various problems caused by the traditional wiring method at a very low cost.

[0048] Since the oil level gauge and secondary line of the transformer oil storage cabinet are completed before delivery, the time for on-site after-sales personnel to install the transformer is reduced, reducing after-sales costs.
