Description

Technical Field

[0001] The utility model relates to the technical field of bus duct oil injection, and particularly relates to a bus duct vacuum oil injection tooling. Background Art

[0002] In the power system, the bus duct is a key component for power distribution and transmission, and the stability and reliability of its performance are crucial. During the operation of the bus duct, to ensure the insulation performance and heat dissipation effect, an appropriate amount of insulating oil is usually filled. The traditional bus duct oil injection process often relies on manual operation, which is not only inefficient but also difficult to accurately control the oil injection volume and the pressure change during the oil injection process, thus affecting the overall performance of the bus duct.

[0003] With the progress of technology, automated oil injection tooling has gradually been applied to the oil injection operation of bus ducts. These toolings evenly inject insulating oil into the bus duct through preset oil outlet pipes, effectively improving the accuracy and efficiency of oil injection. However, there are still some deficiencies in the existing bus duct vacuum oil injection tooling. Especially when dealing with bus ducts of different specifications or requirements, the number of oil outlet pipes on the tooling often needs to be adjusted according to the actual situation. If there are too many oil outlet pipes designed on the tooling but not all need to be opened during actual use, the redundant oil outlet pipes need to be blocked by additional measures. This not only increases the operation complexity but also may cause problems such as oil leakage or uneven pressure distribution due to improper blocking. In addition, the existing oil injection tooling has relatively limited means for monitoring and controlling the oil circuit pressure. It usually relies on externally installed pressure sensors to achieve this, which not only increases the cost but also may not accurately reflect the true pressure situation inside the tooling main body due to the limitation of the sensor installation position, thus affecting the oil injection efficiency and effect. Therefore, in view of the above technical problems, a bus duct vacuum oil injection tooling is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bus duct vacuum oil injection tooling. By driving a rotating shaft with a driving motor, a pressing plate rotates and drives a connecting rod to slide, and then drives a sliding plate to move, effectively blocking redundant oil outlet pipes and realizing flexible adjustment of the quantity. In addition, the sliding plate can also sense the internal pressure in real time, and transmit it to a pressure sensor through the connecting rod and the pressing plate, realizing the intuitive monitoring of the oil circuit pressure inside the tooling main body without adding additional monitoring equipment, and the operation is convenient.

A sliding rod 8 is fixedly connected to one side of the sliding plate 7, and the sliding rod 8 is slidably connected with the second sealing plate 3. An installation sleeve 10 is fixedly connected to the outside of the second sealing plate 3. A chute 11 is opened on the outside of the installation sleeve 10. A connecting rod 12 is fixedly connected to the outside of the sliding rod 8, and the connecting rod 12 is slidably connected with the chute 11 and protrudes outside the installation sleeve 10. A deflection mechanism is installed on the outside of the installation sleeve 10.

[0026] The oil injection mechanism includes an oil outlet pipe 5 and a connection disk 6. The oil outlet pipe 5 is fixedly connected to both sides of the tooling main body 1, and the number of the oil outlet pipes 5 is several groups and is arranged horizontally. The connection disk 6 is fixedly connected to the outside of the oil outlet pipe 5, and a screw hole is opened on the outside of the connection disk 6.

[0027] The number of the sliding rods 8 is two groups and is symmetrically arranged. A sealing ring 9 is fixedly connected to the outside of the second sealing plate 3, and the sliding rod 8 is slidably connected with the sealing ring 9. The sealing ring 9 can prevent gasoline in the tooling main body 1 from leaking.

[0028] The deflection mechanism includes a rotating shaft 14 and a pressing plate 15. The rotating shaft 14 is rotatably connected to the outside of the installation sleeve 10.
