Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to a disconnecting switch driving device. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power supplies, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has a specified insulation distance between its contacts and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) for a specified time.

[0003] Currently, when disconnecting switches are installed on high-voltage power line towers in the field, they need to be disconnected before subsequent manual maintenance. The disconnection method usually requires manual cutting of the connection part of the disconnecting switch by holding an insulating rod. Due to the large weight of the insulating rod and the manual operation, errors are easily made during the operation, resulting in damage to the connection part of the insulating switch or a slow disconnection process, which can easily generate electric arcs for a long time and damage the connection part. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a disconnector switch driving device. The basic concept of the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows:

[0005] A disconnector drive device includes two mounting plates, two bridge plates fixed between opposite sides of the two mounting plates, a disconnector switch provided on the top of each of the two bridge plates, the disconnector switch including two ceramic resistors, the two ceramic resistors being disposed on the top of the bridge plates near the two side edges, and threaded sleeves fixed to the bottom of each of the two ceramic resistors, the bottom of each of the two threaded sleeves extending through to the bottom of the bridge plate.

[0006] Optionally, both of the threaded sleeves are provided with locking nuts on their outer surfaces, and the tops of the two locking nuts are in contact with the bottom of the bridging plate.

[0007] Optionally, each of the two ceramic resistors has a copper bushing at its top, and the bottom of each of the two copper bushings extends into the interior of the ceramic resistor.

[0008] Optionally, a mating copper seat is slidably disposed between the inner walls of one of the copper bushings, and an opening is provided on the top of the mating copper seat and the top of the two ceramic resistors.

[0009] Optionally, a gate is rotatably provided between the inner walls of the other copper sleeve via a torque shaft. One end of the gate extends to the other copper sleeve, and constraint openings are provided on both outer surfaces of the gate near one edge.

[0010] Optionally, spring clamps are provided on the inner walls of both sides of the opening on the docking copper seat, and the two spring clamps are respectively engaged inside the constraint opening.

[0011] Optionally, a support ring is fixed between the inner walls of one of the ceramic resistors, and a spring is fixed between the top of the support ring and the bottom of the mating copper seat. A rotating block is rotatably arranged at the bottom of the mating copper seat, and an insulating pull rope is connected to the bottom of the rotating block. The bottom end of the insulating pull rope extends from the inside of the threaded sleeve to the bottom of the ceramic resistor.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. In this utility model, a spring is fixed between the top of the support ring and the bottom of the docking copper seat. The elastic force of the spring can keep the docking copper seat always located on the inner top surface of the ceramic resistor, and the top of the docking copper seat extends into the interior of the copper sleeve, so as to facilitate engagement with one end of the gate. During engagement, the spring clamp and the constraint port engage with each other. A rotating block is set at the bottom of the docking copper seat, and an insulating pull rope is set on the rotating block. Then, the bottom end of the insulating pull rope extends to the bottom of the ceramic resistor. When the gate is separated from the docking copper seat, the docking copper seat can be slid downward by pulling the insulating pull rope, thereby releasing the engagement between the spring clamp and the constraint port, and separating the gate from the docking copper seat.

[0014] 2. In this utility model, one end of the gate plate is rotatably connected to the inside of the copper sleeve through a torque shaft. After the insulated traction rope pulls downward to separate the gate plate from the docking copper seat, a certain torque is generated by the torque shaft to drive the gate plate to reset.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, as Figure 1-4 As shown, this utility model provides a technical solution for a disconnecting switch driving device: it includes two mounting plates 1, two bridge plates 2 are fixed between opposite sides of the two mounting plates 1, a disconnecting switch is provided on the top of each of the two bridge plates 2, the disconnecting switch includes two ceramic resistors 3, the two ceramic resistors 3 are located on the top of the bridge plates 2 near the two side edges, and threaded sleeves 11 are fixed to the bottom of each of the two ceramic resistors 3, the bottom of each of the two threaded sleeves 11 extends through to the bottom of the bridge plate 2.

[0026] The effect achieved by the entire embodiment 1 is that a spring 14 is fixed between the top of the support ring 13 and the bottom of the docking copper seat 7. The elastic force of the spring 14 can keep the docking copper seat 7 always located on the inner top surface of the ceramic resistor 3, and the top of the docking copper seat 7 extends into the interior of the copper sleeve 4, so as to facilitate engagement with one end of the gate plate 5. When engaging, the spring clamp 12 engages with the constraint port 6. A rotating block 15 is set at the bottom of the docking copper seat 7, and an insulating pull rope 10 is set on the rotating block 15. Then, the bottom end of the insulating pull rope 10 extends to the bottom of the ceramic resistor 3. When the gate plate 5 is separated from the docking copper seat 7, the docking copper seat 7 can be slid downward by pulling the insulating pull rope 10, thereby releasing the engagement between the spring clamp 12 and the constraint port 6, and separating the gate plate 5 from the docking copper seat 7.

[0027] Example 2, as Figure 1-4As shown, locking nuts 9 are provided on the outer surfaces of both threaded sleeves 11. The tops of both locking nuts 9 are in contact with the bottom of the bridge plate 2. Copper bushings 4 are provided on the tops of both ceramic resistors 3. The bottoms of both copper bushings 4 penetrate into the interior of the ceramic resistors 3. A mating copper seat 7 is slidably provided between the inner walls of one of the copper bushings 4. An opening 8 is provided on the top of the mating copper seat 7 and the tops of both ceramic resistors 3. A gate 5 is rotatably provided between the inner walls of the other copper bushing 4 via a torque shaft. One end of the gate 5 extends onto the other copper bushing 4. A constraint opening 6 is provided near one edge on the outer side surface. Spring clamps 12 are provided on the inner walls of the openings 8 on the docking copper base 7. The two spring clamps 12 are respectively engaged inside the constraint openings 6. A support ring 13 is fixed between the inner walls of one of the ceramic resistors 3. A spring 14 is fixed between the top of the support ring 13 and the bottom of the docking copper base 7. A rotating block 15 is rotatably provided at the bottom of the docking copper base 7. An insulating pull rope 10 is connected to the bottom of the rotating block 15. The bottom end of the insulating pull rope 10 extends from the inside of the threaded sleeve 11 to the bottom of the ceramic resistor 3.

[0028] The effect achieved by the entire embodiment 2 is that one end of the gate plate 5 is rotatably connected to the inside of the copper sleeve 4 through the torque shaft. After the insulated traction rope 10 pulls downward to separate the gate plate 5 from the docking copper seat 7, a certain torque is generated by the torque shaft to drive the gate plate 5 to reset.

[0029] Working principle: A spring 14 is fixed between the top of the support ring 13 and the bottom of the docking copper seat 7. The elastic force of the spring 14 keeps the docking copper seat 7 located on the inner top surface of the ceramic resistor 3, and extends the top of the docking copper seat 7 into the interior of the copper sleeve 4, thus facilitating engagement with one end of the gate 5. During engagement, the spring clamp 12 engages with the constraint port 6. A rotating block 15 is set at the bottom of the docking copper seat 7, and the insulating pull rope 10 is set on the rotating block 15. The bottom end of the insulating pull rope 10 extends below the ceramic resistor 3. When separating the gate plate 5 from the docking copper seat 7, the docking copper seat 7 can be slid downward by pulling the insulating pull rope 10, thereby releasing the engagement between the spring clamp 12 and the constraint port 6, and separating the gate plate 5 from the docking copper seat 7. One end of the gate plate 5 is rotatably connected to the inside of the copper sleeve 4 through the torque shaft. After the insulating pull rope 10 pulls downward to separate the gate plate 5 from the docking copper seat 7, a certain torque is generated by the torque shaft to drive the gate plate 5 to reset.
