[0002] GIL busbars are widely used in high-voltage and ultra-high-voltage power transmission. Traditional GIL busbar housings are mostly one-piece structures, which cause many inconveniences in transportation, installation, and maintenance.

[0003] The large size of the unibody casing requires special transportation equipment, resulting in higher costs. During installation, its large size places stringent requirements on the installation site and equipment, making installation difficult. During maintenance and repair, if local damage occurs, the entire unit often needs to be replaced, leading to high maintenance costs and long repair times. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a split-type GIL busbar housing, which solves the problem that the integrated GIL busbar housing is bulky and inconvenient for transportation and maintenance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-type GIL busbar housing, including an end cap and a busbar unit. The outer wall of the end cap is fixedly connected to the inner wall of the busbar unit. The busbar unit includes a unit shell, which constitutes the main structure of the busbar unit. An air filter is fixedly connected to the inner wall of the unit shell. The air filter effectively filters dust and other impurities from the outside air, preventing them from entering the busbar unit. A male connector is fixedly connected to one end of the inner wall of the unit shell, and a female connector is fixedly connected to the other end. Through the cooperation of the male and female connectors, rapid connection and separation between multiple busbar units can be achieved. A support base is fixedly connected to the inner wall of the unit shell. Ventilation holes are provided in the wall of the unit shell, and these ventilation holes are arranged in a linear array along the outer wall of the unit shell. The ventilation holes facilitate gas exchange between the inside and outside of the busbar unit and balance the air pressure.

[0008] Preferably, a protective tube is fixedly connected to the inner wall of the support base. The protective tube protects the internal conductor protection tube and other components, preventing damage from external factors. The conductor protection tube is slidably connected to the inner wall of the protective tube. This sliding connection facilitates the installation, disassembly, and maintenance of the conductor protection tube. A sealing ring is fitted on the outer wall of the conductor protection tube. The sealing ring further enhances the sealing between the conductor protection tube and the protective tube, ensuring the reliability of the gas insulation environment.

[0009] Preferably, the male connector includes a male connector base, which serves as the basic structure of the male connector and supports other components. A tension spring is fixedly connected to the inner wall of the male connector base, providing elastic force for the connection between the male connector and the female connector. An iron block is fixedly connected to the outer wall of the tension spring, and a permanent magnet is provided above the iron block. The iron block and the permanent magnet cooperate with each other to provide magnetic locking force during connection. An operating handle is fixedly connected to the outer wall of the permanent magnet, which allows the operator to manually control the connection and separation of the male connector and the female connector.

[0010] Preferably, the outer wall of the operating handle is slidably connected to the inner wall of the unit housing. This slidable connection ensures smooth movement of the operating handle during operation and also ensures the stability of the connection between it and the unit housing.

[0011] Preferably, the female connector includes a female connector base, which is the main structure of the female connector. A connecting tenon is fixedly connected to the outer wall of the female connector base. The connecting tenon mates with the corresponding structure of the male connector to achieve precise docking and a stable connection.

[0012] Preferably, the connecting tenon and the male connector body are slidably connected. Specifically, the structure of the connecting male connector and the structure of the connecting female connector can cooperate with each other. Through the synergistic effect of components such as tension spring, iron block, permanent magnet and connecting tenon, a convenient and stable connection is achieved.

[0013] (III) Beneficial Effects

[0014] This utility model provides a split-type GIL busbar housing. It has the following advantages:

[0015] (I) This split-type GIL busbar housing, through its split design, allows each busbar unit to be quickly connected and disassembled via male and female connectors. It can be transported separately during transportation, reducing the requirements for transportation equipment. Ordinary transportation tools can be used, saving transportation costs. The installation process is simpler and faster, eliminating the need for complex large-scale installation equipment and cumbersome operating procedures, reducing installation time and manpower input, and improving installation efficiency.

[0016] (ii) This split-type GIL busbar housing prevents dust and other impurities from entering the pipe by setting an air filter. At the same time, since the cross-section of the pipe is trapezoidal, wider at the top and narrower at the bottom, it is conducive to natural air convection. The inner wall of the air duct is smooth to reduce air flow resistance. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a split-type GIL busbar housing, including an end cap 1 and a busbar unit 2. The outer wall of the end cap 1 is fixedly connected to the inner wall of the busbar unit 2. The busbar unit 2 includes a unit shell 21. An air filter 22 is fixedly connected to the inner wall of the unit shell 21. A male connector 23 is fixedly connected to one end of the inner wall of the unit shell 21, and a female connector 24 is fixedly connected to the other end of the inner wall of the unit shell 21. A support base 25 is fixedly connected to the inner wall of the unit shell 21. Ventilation holes 29 are opened in the wall of the unit shell 21, and the ventilation holes 29 are arranged in a linear array along the outer wall of the unit shell 21.

[0025] A protective tube 26 is fixedly connected to the inner wall of the support base 25, and a conductor protection tube 27 is slidably connected to the inner wall of the protective tube 26. A sealing ring 28 is sleeved on the outer wall of the conductor protection tube 27.

[0026] The male connector 23 includes a male connector base 231. A tension spring 232 is fixedly connected to the inner wall of the male connector base 231. An iron block 233 is fixedly connected to the outer wall of the tension spring 232. A permanent magnet 234 is provided above the iron block 233. An operating handle 235 is fixedly connected to the outer wall of the permanent magnet 234.

[0027] The connecting tenon 242 is slidably connected to the male head seat 231. The connecting female head 24 includes a female head seat 241. The outer wall of the female head seat 241 is fixedly connected with the connecting tenon 242. The connecting male head 23 and the connecting female head 24 are adapted to each other.

[0028] When using, an appropriate number of busbar units 2 should be selected for series connection according to the actual site conditions. When connecting busbar units 2 in series, it is necessary to ensure that the male connector 23 fixed at one end of the inner wall of the outer shell 21 of each busbar unit 2 is aligned with the female connector 24 at the other end of the inner wall of the outer shell 21 of another busbar unit 2. The operator pulls the operating handle 235 outward along the sliding track on the inner wall of the unit shell 21, causing the permanent magnet 234 to move synchronously, thereby reducing the distance between the permanent magnet 234 and the iron block 233. When the two reach a specific position, the permanent magnet 234 generates a magnetic attraction force on the iron block 233, pulling the iron block 233 to move outward against the elastic force of the tension spring 232. As the iron block 233 moves, it is embedded in the interior of the connecting tenon 242 that is fixedly connected to the female head seat 241. Through the dual action of magnetic attraction force and tenon structure, the movement of the iron block 233 is restricted, thereby making the connecting male head 23 and the connecting female head 24 tightly connected. The outer wall of the operating handle 235 is slidably connected to the inner wall of the unit shell 21, ensuring smooth operation.

[0029] Multiple busbar units 2 connected in series form the GIL busbar housing, and its two ends are connected to the cable terminal and the overhead line terminal tower respectively through end caps (1). However, during installation, it is necessary to carefully check the inside of the end caps (10) and the tube housing (21) to ensure that no irrelevant items are left inside. Since the end cap (11) is fixedly connected to the end of the tube (1) away from the tube body (2), if irrelevant items remain inside, it may affect the connection stability and the overall performance of the GIL busbar housing. After the inspection is completed and confirmed to be correct, the subsequent installation operations can be carried out to achieve the complete and reliable installation of the GIL busbar housing.

[0030] Inside the busbar unit 2, the support base 25 is fixedly installed on the inner wall of the unit shell 21, and its inner wall is connected to the protective tube 26. The inner wall of the protective tube 26 is slidably connected to the conductor protection tube 27. This design facilitates the installation and disassembly of the conductor protection tube 27. The sealing ring 28 on the outer wall of the conductor protection tube 27 not only enhances the sealing between it and the protective tube 26, but also effectively ensures the stability of the internal protective gas environment and prevents gas leakage during the series assembly process.

[0031] In addition, when the equipment is running, outside air enters the bus unit 2 through the vent 29, is filtered by the air filter 22, and then circulates inside. Due to the special trapezoidal cross-section design of the unit shell 21, it is conducive to natural air convection. Combined with the smooth inner wall of the unit shell 21, it reduces air flow resistance and achieves good heat dissipation and gas circulation.

[0032] If the equipment malfunctions and requires maintenance, the operator uses the operating handle 235 to move the permanent magnet 234 away from the iron block 233. When the permanent magnet 234 and the iron block 233 are outside the effective magnetic force range, the permanent magnet 234 no longer generates magnetic attraction to the iron block 233. At this time, the tension spring 232 returns to its deformation and uses its own elasticity to pull the iron block 233 back into the male connector housing 231, thereby releasing the locking state of the male connector 23 and the female connector 24 and separating the two. After completion, reassemble according to the above installation steps to ensure the normal operation of the split GIL busbar housing.
