Description

Technical Field

[0001] The invention relates to the field of busbar assembly, and in particular to a busbar assembly device for a switchgear. Background Art

[0002] Gas Insulated Metal Enclosed switchgear (GIS) is widely used in substations. Its operation stability directly affects the stability of power transmission lines and substations. Quality problems will cause significant economic losses. Busbars are key components of GIS equipment, and their assembly reliability and safety are crucial.

[0003] like Figure 1 As shown, the GIS includes a cylinder 11 and a conductive rod 12 inserted in the cylinder. The end of the cylinder 11 is provided with a flange protruding from the outer circumference of the cylinder 11, and a pot-type insulator 13 is installed on the flange. The pot-type insulator 13 is provided with an electric connector 14 connecting the two ends of the pot-type insulator. The electric connector 14 is cylindrical and is plugged into the conductive rod 12. During the installation process, the pot-type insulator 13 is first installed at one end of the cylinder 11, and then the end of the conductive rod 12 is pushed into the electric connector 14.

[0004] In the prior art, busbar assembly tooling is used during the installation of conductive rods. For example, Chinese invention patent application with application publication number CN113541072A discloses a support device and a GIL busbar assembly tooling, wherein the tooling includes multiple support devices, a single support device is provided with a locking structure for fixing the conductive rod and a support seat for lifting and lowering, the conductive rod is supported by the support seat, and multiple support devices can be lifted and lowered to adjust the axial position of the conductive rod until the axis of the conductive rod is in line with the axis of the electrical connector. At this time, the centering is completed, and then the conductive rod is inserted.

[0005] However, the above solution can only realize the centering of the conductive rod, and the insertion of the conductive rod still relies on manual pushing. The conductive rod is long and heavy, and direct pushing requires a large torque. In order to maintain a stable electrical connection between the electrical connector and the conductive rod, a contact finger is also provided in the electrical connector for elastic contact and cooperation with the conductive rod, which further increases the resistance during the pushing process. In the process of installation and pushing, improper force application may damage the pot insulator and injure the person applying the force. Summary of the invention

[0006] The object of the present invention is to provide a switchgear busbar assembly device, which is used to solve the problem in the prior art that during the assembly process of the switchgear busbar, the conductive rod is manually pushed and the pushing resistance is large, which may cause improper force to damage the insulator and injure the person applying the force.

[0007] To achieve the above purpose, a switchgear busbar assembly device in the present invention adopts the following technical solution:

Since the pushing member can move laterally relative to the frame, it is only necessary to apply force to the input structure of the transmission mechanism, and the output structure of the transmission structure will push the conductive rod to move laterally, so that the conductive rod enters the electrical connecting member, avoiding direct manual operation of the conductive rod and changing it to operation by the transmission mechanism, thereby solving the problem in the prior art that the conductive rod of the switch equipment busbar is pushed manually during assembly and the pushing resistance is large, which makes it easy to damage the insulator and injure the person applying the force due to improper force.

[0010] Furthermore, the pushing member includes a mounting seat for plugging and matching with the end of the conductive rod, and a mounting groove for inserting the end of the conductive rod is provided in the mounting seat.

[0011] The beneficial effect of the above technical solution is that the conductive rod can be easily fixed by the mounting seat, thereby preventing the end of the conductive rod from being separated from the mounting seat during the installation process.

[0012] Furthermore, a protection structure is provided in the installation groove for protecting the outer peripheral surface of the conductive rod during contact with the conductive rod.

[0013] The beneficial effect of the above technical solution is to avoid wear on the conductive rod during the installation process.

[0014] Furthermore, the fixing structure is a clamp, which is used to engage with the flange of the cylinder, and the clamp includes at least two, and the plurality of clamps are arranged along the circumference of the cylinder.

[0015] The beneficial effect of the above technical solution is that it is easy to be clamped with the flange of the cylinder, and at least two clamps are provided to facilitate clamping at different positions on the cylinder, and the clamping effect is better.

[0016] Furthermore, the clamps are hinged on the frame, and each clamp has a clamping end for cooperating with a cylinder flange stopper. The clamps have a clamping station for clamping the cylinder flange during the rotation of the frame.

[0017] The beneficial effects of the above technical solution are: the structure is simple, and it is convenient to fix the position of the switchgear busbar assembly device and the cylinder by rotating the clamp.

[0018] Furthermore, an elastic member is connected between the clamp and the frame, and the elastic member is used to deform under force when the clamp is in the clamping position so that the clamp clamps the cylinder flange.

[0019] The beneficial effect of the above technical solution is that the clamping is firm and the clamp is prevented from being disengaged from the cylinder during the installation process.

[0020] Furthermore, the transmission mechanism includes a worm screw lift and a pushing handwheel, the input shaft of the worm screw lift constitutes an input structure, and both ends of the input shaft extend to the outside of the frame respectively and are both equipped with the pushing handwheel.

[0021] The beneficial effect of the above technical solution is that the turbine screw lift is convenient for amplifying the torque, which has a labor-saving effect, and the push handwheel is provided with two ends respectively arranged at both ends of the input shaft to facilitate busbar assembly in different orientations.

[0022] Furthermore, the frame includes a support seat and a vertically arranged mounting plate, the fixing structure, the pushing member and the transmission mechanism are fixedly arranged on the mounting plate, and the support seat is provided with a lifting mechanism for controlling the lifting of the mounting plate.

[0026] Furthermore, the input shafts of the two worm screw lifts are fixedly connected together so that the two worm screw lifts can move synchronously.

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] In the embodiment 1 of the switchgear busbar assembly device (hereinafter referred to as the assembly device) of the present invention:

[0036] In this embodiment, a frame and a clamp hinged on the frame are provided, and the clamp can be used to be clamped and matched with the flange on the cylinder. A push rod and a mounting seat at the end of the push rod are also passed through the frame, and the mounting seat cooperates with the end of the conductive rod, and then the push rod is driven by the transmission mechanism to move to push the conductive rod.

[0037] Specifically, Figure 2 and Figure 3 As shown, the assembly device in this embodiment includes a frame and a fixed structure, the fixed structure is a clamp 2, and a pushing member for thrust-cooperating with the conductive rod 12 and a transmission mechanism for pushing the pushing member are also provided on the frame. An output structure connected to the pushing member and an input structure for applying force are provided on the transmission mechanism. A pushing handwheel 51 is connected to the transmission mechanism, that is, the pushing handwheel 51 can transfer torque to the pushing member through the transmission mechanism, thereby pushing the conductive rod 12.

[0038] The frame includes a mounting plate 41 and a support seat 42, and a walking wheel 43 is provided at the bottom of the support seat 42 toward the bottom surface, and the walking wheel 43 facilitates the assembly device to be moved to the corresponding position for use. The fixture 2, the pusher and the transmission mechanism are fixedly arranged on the mounting plate 41. Specifically, the mounting plate 41 is arranged vertically in the use state, and the mounting plate 41 is a rectangular plate. There are two fixtures 2, which are respectively located in the middle position of the upper and lower sides of the mounting plate 41 to facilitate the clamping and fixing of the cylinder 11. The pusher is arranged in the middle position of the two fixtures 2, so that when the fixture 2 is clamped to the flange of the cylinder 11, the pusher coincides with the axis of the cylinder 11, which is convenient for coaxial arrangement with the conductive rod 12 in the cylinder 11, and then convenient for pushing. In addition, in order to facilitate the movement of the assembly device, a handle 7 for pushing the mounting plate 41 is also provided on the mounting plate 41, and the handle 7 is a U-shaped structure fixed on the mounting plate 41 for easy holding.

[0039] The clamp 2 is used to be engaged with the flange on the cylinder 11, and each clamp 2 has a clamping end for engaging with the flange stopper. In this embodiment, the clamp 2 is a pipe with bent ends, that is, the pipe is bent into an L shape, wherein one end of the L shape constitutes a clamping section, and one end of the clamp 2 away from the clamping section is hingedly arranged on the mounting plate 41, and in order to facilitate better clamping with the cylinder 11, the clamp 2 is arranged along the circumference of the cylinder 11. In order to facilitate the stable cooperation between the clamp 2 and the cylinder 11, an elastic member for connecting the clamp 2 and the frame respectively is also provided between the clamp 2 and the frame. In this embodiment, the elastic member is a tension spring 8, wherein one end of the tension spring 8 on the clamp 2 at the bottom is connected to the clamp 2, and the other end is connected to the support seat 42; one end of the tension spring 8 on the clamp 2 at the top is connected to the clamp 2, and the other end is used to connect to the mounting plate 41, so that when the clamp 2 is opened, it has the power to make the two clamps 2 move toward each other, that is, when clamped, the clamp 2 can be clamped tighter and tighter on the cylinder 11.

[0040] In this embodiment, the transmission mechanism is a turbine screw lift, which has an input shaft and an output shaft, wherein the output shaft of the turbine screw lift constitutes the output structure of the transmission mechanism, that is, in this embodiment, the push output shaft 52 is fixedly connected to the push member for pushing the end of the conductive rod 12, and a push handwheel 51 is provided on the input shaft of the turbine screw lift, and the two ends of the input shaft are respectively located at the ends of the mounting plate 41, and the push handwheel 51 has two ends respectively arranged at the two ends of the input shaft. That is to say, the two push handwheels 51 are located on both sides of the assembly device, so that the transmission mechanism can be driven by rotating one of the push handwheels 51. In this way, in actual use, it can be used even if one side is blocked.

[0041] A mounting seat 3 is provided at the end of the push output shaft 52, and a mounting groove is provided on the mounting seat 3 for inserting the end of the conductive rod 12. During the pushing process, the end of the conductive rod 12 cooperates with the mounting groove to avoid slipping out. It is worth noting that during the installation process, it is necessary to avoid damage to the conductive rod 12 as much as possible, so a protective structure for protecting the conductive rod 12 during the contact process is provided on the mounting seat 3. In this embodiment, the protective structure is a non-metallic material provided on the mounting seat 3. The structural strength of the non-metallic material is less than the strength of the conductive rod 12, so as to avoid wear on the outer peripheral surface of the conductive rod 12.

[0042] In addition, in order to adapt to more types of switchgear, a lifting mechanism for controlling the lifting of the mounting plate 41 is also provided on the support seat 42. In order to control the lifting mechanism, a lifting handwheel 61 is also provided for connecting with the lifting mechanism to drive the lifting mechanism to rotate. The lifting mechanism is a worm screw lift, where the output shaft of the worm screw lift constitutes a lifting output shaft 62, and the input shaft is connected to the lifting handwheel 61. In order to better support the mounting plate 41, two lifting mechanisms are provided, two of which are symmetrically arranged along the axis of the mounting plate 41, and the lifting output shaft 62 is fixedly connected to both sides of the mounting plate 41, and two lifting handwheels 61 are also provided. The two lifting handwheels 61 are respectively connected to the input shafts of the worm screw lifts for lifting, and the input shafts are fixedly connected together so that the two worm screw lifts rotate synchronously. In this embodiment, the input shafts of the two lifting mechanisms are fixedly connected through a coupling 63. That is to say, in this embodiment, a total of three worm screw lifts are provided, of which one at the top is used as a transmission mechanism, and two at the bottom are used as lifting mechanisms.

[0043] like Figure 4 and Figure 5 As shown, when in use, first push the handle 7 to move the assembly device to the corresponding position, and adjust the lifting hand wheel 61 to make the height appropriate, that is, at this time, the axis of the push rod coincides with the axis of the conductive rod 12. Then, open the two clamps 2 so that the clamps 2 can be engaged with the flange on the cylinder 11 of the busbar, and then the clamps 2 will be engaged with the flange of the cylinder 11 under the action of the elastic member, and finally turn the push hand wheel 51 to drive the movement of the push rod and the mounting seat 3, so that the mounting seat 3 drives the conductive rod 12 to move to the corresponding position to complete the installation.
