[0002] With the increasing load on the power grid and the extended service life of open-type disconnecting switchgear, overheating of the contact parts of the disconnecting switches is becoming more and more frequent due to adverse factors such as external environmental pollution and equipment aging, affecting the reliability and even safety of power plant operation. Currently, the main approach to dealing with overheating disconnecting switches is to first shut down the power, then determine the cause of the problem based on images of the overheating switch and the relative temperature difference, shut down the power again after analyzing the cause of the overheating, and then carry out targeted inspection and maintenance.

[0003] However, if a problem of overheating occurs, a power outage could worsen the problem and affect operational safety.

[0004] When the losses from a power outage are too great, live-line work can be used for repair and inspection. In this case, the machine is operating with the faults but without power interruption. Maintenance personnel need to equip themselves with insulating shielding tools and work in shifts, and there is no way to avoid the risks.

[0005] The existing technologies currently have the following main problems:

[0006] 1. Power outages are costly to handle, consuming manpower and resources while significantly impacting the operation of the power grid, causing inconvenience to industrial production and residents' lives.

[0007] 2. Operating a faulty circuit without power interruption poses significant safety risks to the circuit operation and also compromises the personal safety of maintenance personnel.

[0010] The mounting bracket includes a stationary contact mounting part and a conductive rod mounting part. The stationary contact mounting part is fixedly connected to the stationary contact contact assembly, and the conductive rod mounting part is fixedly connected to the conductive rod contact assembly.

[0011] The stationary contact assembly includes a first contact portion for contacting the stationary contact bend of the disconnecting switch, and the conductive rod contact assembly includes a second contact portion for contacting the conductive rod of the disconnecting switch; both the first and second contact portions are vertically arranged.

[0012] The mounting bracket has mounting holes for detachable connection with the insulating mounting components.

[0013] Furthermore, the stationary contact assembly includes a stationary contact finger mounting block and a first contact portion; wherein the stationary contact finger mounting block and the stationary contact mounting portion are detachably connected.

[0016] The second contact portion includes a vertically arranged third spring plate and a fourth spring plate, both of which are detachably connected to the conductive rod contact finger mounting block. The third spring plate and the fourth spring plate are arranged opposite to each other to clamp the conductive rod.

[0017] Furthermore, the stationary contact assembly also includes two stationary contact fingers, one of which is fixedly connected to the lower end of the first spring plate, and the other stationary contact finger is fixedly connected to the lower end of the second spring plate.

[0018] The conductive rod contact assembly also includes two conductive rod contact fingers, one of which is fixedly connected to the lower end of the third spring plate, and the other conductive rod contact finger is fixedly connected to the lower end of the fourth spring plate.

[0019] Furthermore, the stationary contact mounting section has multiple sets of fixing holes for detachable connection with the stationary contact finger mounting block.

When the contacts heat up, the conductive rod contact assembly is fixedly connected to the conductive rod of the horizontal disconnector, and the stationary contact assembly is fixedly connected to the stationary contact bend of the horizontal disconnector. The short-circuiting device is then installed on the vertical disconnector.

[0039] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in the present invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of the invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to the methods, devices, and materials in the embodiments of the present invention.

[0040] Please see Figure 1-3 The present invention provides a short-circuit device for heating the contacts of a horizontal disconnect switch under energized conditions, comprising a mounting frame 1, a stationary contact assembly 7, a conductive rod contact assembly 8, and an insulating mounting assembly 4; wherein, the mounting frame 1 includes a stationary contact mounting part 2 and a conductive rod mounting part 3, the stationary contact mounting part 2 being fixedly connected to the stationary contact assembly 7, and the conductive rod mounting part 3 being fixedly connected to the conductive rod contact assembly 8.

[0041] Mounting bracket 1 is made of conductive material and can be in the shape of an arc, right angle, obtuse angle, etc.

[0042] The first contact portion 5, the stationary contact finger mounting block 13, the mounting bracket 1, the conductive rod contact finger mounting block 14, and the second contact portion 6 are all made of conductive material, so that the path formed by the above components can shunt the horizontal disconnect switch.

[0043] Both the stationary contact finger 15 and the conductive rod contact finger 16 are made of insulating material, so that if the first contact part 5 and the second contact part 6 are misaligned after being fixed, the contact finger can be adjusted by adjusting the contact finger.

[0044] The stationary contact assembly 7 is provided with a first contact portion 5 for contacting the stationary contact bend 9 of the disconnecting switch, and the conductive rod contact assembly 8 is provided with a second contact portion 6 for contacting the conductive rod 10 of the disconnecting switch; both the first contact portion 5 and the second contact portion 6 are arranged vertically.

[0045] Those skilled in the art should understand that horizontal disconnect switches are commonly used disconnect switch devices, and their structure is as follows: Figure 1 It mainly includes a stationary contact bent plate 9, a stationary contact rod 11, a moving contact piece 12, and an upper conductive rod 10 connected in sequence. The stationary contact bent plate 9 is set in the vertical direction parallel to the moving contact piece 12 and the upper conductive rod 10. The stationary contact rod 11 is set in the vertical direction and connects to the moving contact piece 12. It is the main position for the contact to heat up.

[0046] Combination Figure 1 It can be seen that the horizontal plate 25 can be set parallel to the stationary contact bending plate 9, while the first contact part 5 is fixedly connected and perpendicular to the horizontal plate 25 and the stationary contact bending plate 9 respectively.

[0047] The vertical plate 26 can be arranged perpendicular to the conductive rod 10, and the second contact portion 6 extends perpendicular to the conductive rod 10 along the length of the vertical plate 16.

[0048] There are many reasons why contacts can overheat. Contacts are generally connected by conductors and serve to conduct current. However, there is a certain contact resistance at the contact. When current flows through the contact, it consumes some electrical energy, which is converted into heat energy, causing the contact to overheat. Under basically the same heat dissipation conditions, the greater the heat generated, the higher the temperature rise, and the more severe the damage to the contact due to corrosion and material fatigue. When the temperature of the contact exceeds the maximum allowable temperature or even higher, overheating occurs. The contact will be severely damaged in a short period of time, resulting in insulation failure, burning, breakage, and other accidents that interrupt the power supply.

[0049] Therefore, by using short-circuiting to reduce the current at the contact points and lessen heat generation, and then treating the contact points after power outage maintenance, the continuous temperature rise and corrosion of the contacts can be prevented from the source, thus stopping the damage in time.

[0050] The mounting bracket 1 has mounting holes 21 that can be detachably connected to the insulating mounting assembly 4.

[0051] In some embodiments, combined with Figure 2 As shown in the structural diagram of the short-circuit device, the mounting bracket 1 can be formed by perpendicularly welding a horizontal plate 25 and a vertical plate 26. When interpreting the orientation of the first contact portion 5, it can be positioned at the end of the horizontal plate 25 away from the vertical plate 26, perpendicular to the horizontal plate in the vertical direction on the inner plane of the mounting bracket 1; and the line segment formed by connecting the two opposing stationary contact finger pieces 15 is perpendicular to the length direction of the horizontal plate 25. (The inner plane of the mounting bracket 1 is the plane with the second largest surface area of ​​the mounting bracket 1).

[0052] When understanding the orientation of the second contact portion 6, the second contact portion 6 can be positioned on the outer plane of the mounting frame 1 along the length of the vertical plate 26, at the end of the vertical plate 26 away from the horizontal plate 25; the line segment formed by the connection between the two opposing conductive rod contact fingers 16 is perpendicular to the plane formed by the length directions of the horizontal plate 25 and the vertical plate 26. (Wherein, the outer surface of the mounting frame 1 is the plane with the largest surface area of ​​the mounting frame 1).

[0053] The insulating mounting component 4 can be detachably connected to the mounting hole 21 on the mounting frame 1 by snap-fit ​​or threaded connection. The movement of the mounting frame 1 can be manually controlled by the insulating component, thereby controlling the connection position and connection method between the mounting frame 1 and the disconnecting switch.

[0054] In some embodiments, the stationary contact assembly 7 further includes a stationary contact finger mounting block 13; wherein the stationary contact finger mounting block 13 is detachably connected to the stationary contact mounting portion 2.

[0055] The stationary contact finger mounting block 13 can be installed on the stationary contact mounting part 2 by means of magnetic attraction or splicing.

[0056] The first contact portion 5 includes a vertically arranged first spring plate 17 and a second spring plate 18. Both the first spring plate 17 and the second spring plate 18 are detachably connected to the stationary contact finger mounting block 13. The first spring plate 17 and the second spring plate 18 are arranged opposite to each other to clamp the stationary contact bent plate 2 in the width direction.

[0057] The spring sheet can be a thin strip, and the elastic force of the first and second spring sheets 17 and 18 after deformation can be used to clamp it vertically to the contact head bend plate, so as to achieve a detachable connection in the vertical direction.

[0058] The first and second spring plates 17 and 18 may have screw holes at the points where they overlap with the stationary contact finger mounting block 13, and the spring plates and the contact finger mounting block may be fixed by bolts.

[0059] The first spring plate 17 and the second spring plate 18 can each be composed of several identical spring plates.

[0060] In some embodiments, the conductive rod contact assembly 8 may include a conductive rod finger mounting block 14; wherein the conductive rod finger mounting block 14 is detachably connected to the conductive rod mounting portion 3.

[0061] The conductive rod contact mounting block 14 can be installed on the conductive rod mounting part 3 by means of magnetic attraction or splicing.

[0062] The second contact portion 6 includes a vertically arranged third spring plate 19 and a fourth spring plate 20. Both the third spring plate 19 and the fourth spring plate 20 are detachably connected to the conductive rod contact finger mounting block 14. The third spring plate 19 and the fourth spring plate 20 are arranged opposite each other in the vertical direction to clamp the conductive rod 10 in the transverse direction.

[0063] Referring to the first spring plate 17, the second spring plate 18, the third spring plate 19, and the fourth spring plate 20 also engage the conductive rod 10 vertically through the elastic force after deformation, and the third spring plate 19 and the fourth spring plate 20 are set parallel to the first spring plate 17 and the second spring plate 18.

[0064] It should also be noted that the relative distance between the first and second spring plates 17 and 18 should be slightly smaller than the outer diameter of the stationary contact bent plate 9; the relative distance between the third and fourth spring plates 19 and 20 should be slightly smaller than the outer diameter of the conductive rod 10, so that the elastic force after the spring plates are deformed is sufficient to fix the short-circuit device.

[0065] In other embodiments, the stationary contact assembly 7 further includes two stationary contact fingers 15, one of which is fixedly connected to the lower end of the first spring sheet 17, and the other is fixedly connected to the lower end of the second spring sheet 18.

[0066] The conductive rod 10 contact assembly also includes two conductive rod contact fingers 16, one of which is fixedly connected to the lower end of the third spring plate 19, and the other is fixedly connected to the lower end of the fourth spring plate 20.

[0067] The stationary contact finger 15 and the conductive rod finger 16 can be flared outwards so that the spring sheet can be smoothly inserted into the stationary contact bent plate 9 and the conductive rod 10, whose outer diameter is slightly larger than the relative position of the spring sheet.

[0068] The stationary contact mounting part 2 has multiple sets of fixing holes 22 for detachable connection with the stationary contact finger mounting block 13. Each set of fixing holes 22 can have 1 to 3 holes, and each set of fixing holes 22 is distributed in parallel on the stationary contact mounting part 2.

[0069] The stationary contact finger mounting block 13 can be screwed to the stationary contact mounting part 2 through the fixing hole 22. The fixing hole 22 can be used to position the stationary contact finger mounting block 13, making it easy to adapt to different sizes of disconnecting switches.

[0070] In some embodiments, the stationary contact mounting portion 2 may include a horizontal plate 25, and the conductive rod mounting portion 3 may include a vertical plate 26. One end of the horizontal plate 25 is fixedly connected to the stationary contact assembly 7, and the other end of the horizontal plate 25 is fixedly connected to one end of the vertical plate 26. The other end of the vertical plate 26 is fixedly connected to the conductive rod contact assembly 8. The horizontal plate 25 and the vertical plate 26 may be integrally formed, and the lengths of both the horizontal plate 25 and the vertical plate 26 can be adjusted according to the specifications of the disconnecting switch.

[0071] For example, the horizontal plate 25 can be arranged parallel to the stationary contact bending plate 9 and clamped onto the stationary contact bending plate 9 through the first contact portion 5; the vertical plate 26 can be arranged perpendicular to the conductive rod 10 and clamped onto the conductive rod 10 through the second contact portion 6.

[0072] That is, the mounting bracket 1 can be L-shaped.

[0073] The first contact portion 5 can be arranged perpendicular to the extension direction of the horizontal plate 25 in the longitudinal direction, and the second contact portion 6 can be arranged parallel to the extension direction of the vertical plate 26 in the longitudinal direction.

[0074] In some embodiments, a handle 23 is provided on the surface of the horizontal plate 25 away from the stationary contact mounting portion 2.

[0075] The short-circuiting device is installed on the upper surface of the horizontal disconnecting switch and has an arc-shaped handle 23. The number of arc-shaped handles 23 can be 2 to 6. Among them, there may be a handle 23 that is set relative to the stationary contact assembly 7 and a handle 23 that is set relative to the conductive rod 10 contact assembly.

[0076] The insulating mounting assembly 4 includes an insulating rod, the surface of which is provided with a hook 24 that engages with the handle 23.

[0077] When the short-circuiting device is disengaged from the horizontal disconnecting switch, the hook 24 is pressed against the handle 23 of the contact assembly 7 relative to the stationary contact, and upward force is applied to disengage the first contact part 5 from the stationary contact bending plate 9; then the hook 24 is pressed against the handle 23 of the contact assembly relative to the conductive rod 10, so that the second contact part 6 is also disengaged from the disconnecting switch, thereby realizing the disassembly of the short-circuiting device.

[0078] In some embodiments, the horizontal plate 25 is also provided with a screw hole, which can be the mounting hole 21, and one end of the insulating rod is provided with a thread that mates with the screw hole. When installing the short-circuit device, the thread of the insulating rod 4 can be aligned with the screw hole first, and then slowly screwed in until it is tightly engaged. The short-circuit device can then be operated using the insulating rod.

[0079] The screw hole can be located on the horizontal plate 25, or a mounting plate can protrude from the horizontal plate 25 or the vertical plate 26 to set the screw hole, i.e., the mounting hole 21.

[0080] refer to Figure 3 The mounting bracket 1 can be welded together from a handle 23, a horizontal plate 25, a vertical plate 26, a mounting hole 21, and a conductive rod contact finger mounting block 14.

[0081] The insulating rod is fixedly connected to the mounting bracket 1 through the screw hole. The short-circuit device is supported by the insulating rod and moved to the contact overheating position, so that the contact finger piece of the conductive rod 10 is locked onto the upper conductive rod 10, and the contact finger piece 15 of the stationary contact is locked onto the stationary contact bending plate 9. Then, by pulling down the insulating rod, the contact fingers are clamped to the conductive rod 10 and the stationary contact bending plate 9 respectively. After the contact is heated and the short-circuit device is installed, the insulating rod is unscrewed and removed to complete the installation of the short-circuit device.

[0082] This invention also provides a horizontal disconnecting switch with energized operation, including a disconnecting switch body and a short-circuiting device as described above. When the short-circuiting device is installed on the horizontal disconnecting switch, the first contact portion 5 uses the elastic force formed by the deformation of the first and second spring plates 17 and 18 in the vertical direction to hold the stationary contact plate 9, so that the wide part of the stationary contact plate is detachably connected to the first contact portion. The third and fourth spring plates 19 and 20 in the second contact portion are oriented in the same direction as the first and second spring plates 17 and 18, and the second contact portion 6 uses the elastic force formed by the deformation of the third and fourth spring plates 19 and 20 in the vertical direction to hold the conductive rod 10. The short-circuiting device is fixedly connected to the horizontal disconnecting switch to achieve current diversion and reduce heat generation.

[0083] To facilitate a further understanding of the present invention by those skilled in the art, the following examples are provided:

[0084] like Figures 1-3As shown, this invention provides a short-circuit device for handling heated contacts of a horizontal disconnecting switch. When the contacts of the horizontal disconnecting switch (the connection between the stationary contact rod 11 and the moving contact piece 12) heat up, the stationary contact finger mounting block 13 is bolted to a suitable fixing hole 22 on the stationary contact mounting part 2, and the threaded end of the insulating mounting assembly 4 is screwed into the threaded hole on the stationary contact mounting part 2 until the insulating mounting assembly 4 is fixedly connected to the mounting bracket 1. The insulating mounting assembly 4 is then pushed upwards, causing the stationary contact finger piece 15 to press against the stationary contact bent plate 9. After the contact finger piece of the conductive rod 10 presses against the conductive rod 10, the insulating mounting assembly 4 is pressed downwards until the first contact part 5 holds the stationary contact bent plate 9 and the second contact part 6 holds the conductive rod 10. A portion of the current is diverted from the stationary contact bending plate 9 and passes sequentially through the first contact part 5, the stationary contact finger mounting block 13, the stationary contact mounting part 2, the conductive rod mounting part 3, the conductive rod finger mounting block 14, and the second contact part 6, forming a constant current diversion, reducing the temperature rise of the disconnecting switch contacts, and mitigating the heat generation.

[0085] During power outage maintenance, use the hook 24 on the insulation rod to lock the handle 23 near the stationary contact assembly 7 to lift the first contact part 5 until the stationary contact finger 15 is disengaged from the stationary contact bending plate 9. Then, use the hook 24 to lock the handle 23 near the conductive rod 10 contact assembly to lift the second contact part 6 until the conductive rod finger 16 is completely disengaged from the conductive rod 10. Remove the short-circuit device from the disconnect switch.
