Description

Technical Field

[0001] This utility model relates to the field of power equipment installation technology, and in particular to a tooling device for installing conductors in long branch busbars of GIS. Background Technology

[0002] GIS (Gas Insulated Switchgear) equipment is widely used in power systems. The installation of long branch busbars requires high precision. Traditional methods rely on manual handling of the conductor, or sometimes a long rod is attached to the outer end of the conductor for lifting by a crane and slowly lowering it into the busbar drum. Due to directional instability, the conductor's tip may hit the inner wall of the busbar drum or the contact seat, causing damage such as dents and peeling of the silver plating, resulting in quality problems. Furthermore, this installation process is time-consuming and labor-intensive, easily damaging the silver plating at the conductor ends and affecting the overall product assembly quality. Its inefficiency also hinders batch installation. Therefore, a specialized tooling device is needed to improve installation efficiency and precision. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a tooling device for installing conductors on long branch busbars of GIS, which saves time and effort, ensures that the product is not damaged, and facilitates batch installation.

[0004] This utility model is achieved through the following technical solution:

[0005] A tooling device for installing conductors on a long branch busbar of a GIS includes two parallel support plates. Each support plate has several circular holes for inserting a connecting rod, which secures the two support plates together. The connecting rod is tightened at both ends by nuts. A semi-circular groove is provided in the center of each support plate to support the conductor. Three U-shaped grooves are provided on the outer edge of each support plate, extending in length. Through holes are located on both sides of the U-shaped grooves for installing shaft pins. PU (polyurethane) silent soft rubber wheels are installed on the shaft pins, positioned within the U-shaped grooves. After installation, a cotter pin is inserted into the end hole of the shaft pin for locking. All soft rubber wheels are located on the same inner circumferential surface of the busbar housing.

[0006] Preferably, a rubber pad is attached to the middle semi-circular groove of the support plate to provide support, prevent damage to the conductor, and reduce vibration.

[0007] More preferably, the PU polyurethane silent soft rubber wheel is a deep groove ball bearing with an outer layer of PU polyurethane. The PU polyurethane can reduce noise and prevent a series of problems caused by indentation and paint peeling on the busbar housing during movement. The bearing structure can reduce movement resistance and effectively increase stability.

[0008] In a further preferred embodiment, the GIS long branch busbar conductor installation tooling is equipped with a traction rope at its end, which is used to pull the tooling out of the busbar housing after the conductor is installed.

[0009] In a further preferred embodiment, the bearing of the PU polyurethane silent soft rubber wheel has retaining rings on both sides, and the shaft pin passes through the middle hole of the retaining ring.

[0010] The beneficial effects of this utility model are as follows: Through the fastening of the connecting rod and the constraint of the PU polyurethane silent soft rubber wheel, the conductor is placed into the semi-circular groove in the center of the support plate. Under the action of the PU polyurethane silent soft rubber wheel bearing, it moves linearly within the busbar cylinder (busbar housing), slowly pushing it into the space between the conductor's front end and the contact seat. A resistance will be felt when pushing it in forcefully, at which point the conductor is installed into the contact seat. This effectively prevents problems such as collisions and misalignment at the ends caused by the lack of this equipment, thus enabling batch assembly, saving time and labor, and increasing efficiency. It is an application device for installing conductors on long branch busbars in high-voltage electrical appliances.

[0011] This utility model discloses a tooling device for installing conductors in GIS long branch busbars. The device can be designed and manufactured according to the dimensions of the busbar drum. Its use significantly reduces labor intensity, ensures installation quality, avoids damage to the silver-plated surface of the conductor ends, and improves work efficiency. Its structure is compact, easy to process, and simple and quick to install. The device consists of two support plates equipped with six PU polyurethane silent soft rubber wheels to prevent indentations and debris caused by rolling during movement inside the drum, ensuring the quality of the product's internal structure and the stability of movement. This device can be manufactured to scale the dimensions of different busbar drums to achieve the desired installation. This enables batch, efficient, and precise installation, suitable for GIS equipment installation in power systems. Attached Figure Description

[0018] The attached figure shows a specific embodiment of this utility model.

[0019] Figure 2 The diagram shows a tooling device 3 for installing conductors on a long branch busbar. It includes two parallel support plates 31 with several circular holes for inserting connecting rods 32, which fix the two support plates together. The connecting rods 32 are secured at both ends by flat washers 33, spring washers 34, and hexagonal nuts 35. A semi-circular groove at the center line of the support plate 31 supports the conductor 6. The support plate 31 is approximately a semi-octagon with three U-shaped grooves along its edges. The U-shaped grooves extend in length and have through holes on both sides for installing pins 38. PU silent soft rubber wheels 36 are installed on the pins 38, located within the U-shaped grooves. After installation, cotter pins 39 are inserted into the holes at the ends of the pins 38 for locking and positioning. All soft rubber wheels are located on the same inner circumferential surface of the busbar housing for support and movement.

[0020] A rubber pad 4 is attached to the middle semi-circular groove of the support plate 31 to provide support, prevent damage to the conductor, and dampen vibrations. The rubber pad effectively prevents damage and quality problems when the conductor is inserted, and also acts as a buffer and shock absorber.

[0021] The PU polyurethane silent soft rubber wheel 36 is a deep groove ball bearing with an outer layer of PU polyurethane. The PU polyurethane helps to reduce noise and prevent indentations and paint peeling on the busbar housing 2 during movement. The bearing structure reduces movement resistance and effectively increases stability. Its outer ring PU polyurethane structure effectively prevents dents and debris from being crushed onto the inner wall of the busbar drum, while the inner ring bearing effectively reduces resistance and improves efficiency.

[0022] The GIS long branch busbar is equipped with a tooling device for installing conductors. The end of the tooling device is equipped with a traction rope 5, which is used to pull the tooling device out of the busbar housing 2 after the conductor 6 is installed.

[0023] The PU polyurethane silent soft rubber wheel 36 has retaining rings 37 on both sides of the bearing, and the shaft pin 38 passes through the middle hole of the retaining ring 37.

[0024] The tooling equipment for installing conductors on the long branch busbar mainly consists of a support plate, connecting rod, M10 hexagonal nut, 10 spring washer, 10 flat washer, PU polyurethane silent soft rubber wheel, retaining ring, shaft pin and cotter pin, etc.

[0025] The usage process is as follows: (e.g.) Figure 1 The diagram illustrates the actual assembly process. Typically, the branch insulator 1 has a contact seat 0 at its center. The outer circumference of the branch insulator 1 is connected to the busbar housing 2. First, a rubber pad 4 is installed at the semi-circular groove in the center of the support plate 31 of the long branch busbar conductor installation fixture 3, fitting tightly along the semi-circular groove. A traction rope 5 is attached to the outer end of this fixture for pulling the fixture out of the busbar housing 2 after conductor installation. After the long branch busbar conductor installation fixture 3 is inserted into the busbar housing 2 a certain distance, the conductor 6 is placed on the rubber pad 4 at the semi-circular groove of the support plate 31 of the long branch busbar conductor installation fixture 3. The operator then pushes the conductor 6 forward at its end until the front end engages with the contact seat 0. A resistance is felt; pushing further will fully engage the conductor 6 with the contact seat 0, completing the assembly task. At this point, the operator slightly lifts the end of conductor 6 and slowly pulls out the traction rope 5 by hand. As a result, the tooling equipment 3 for installing conductors on the long branch busbar is pulled out, and the inside of the busbar housing 2 is cleaned to await the next assembly task.

[0026] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
