Description

Technical Field

[0001] The present invention relates to the technical field of switches, and particularly to a grounding switch mechanism for high and low voltage power distribution cabinets. Background Art

[0002] As the name implies, high and low voltage power distribution cabinets are power distribution equipment used for power distribution, control, metering, and connection of cables in a power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, and then the low voltage side is led out through a transformer step-down to the low voltage power distribution cabinet. The low voltage power distribution cabinet then goes to each power distribution panel, control box, and switch box for power consumption. Inside, it is a power distribution device that assembles some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protection devices to meet the design function requirements.

[0003] The grounding switches installed in existing high and low voltage power distribution cabinets are mechanical switches with a special purpose that have a certain ability to close short-circuit currents. They are used to ground the switch cabinet during the maintenance of high voltage switch cabinets and their lines to protect personal safety. In addition, due to possible short-circuit faults in the circuit, the grounding switch needs to quickly ground the power distribution cabinet to facilitate maintenance by staff. However, during the closing and opening processes of the grounding switch, the moving contact and the static contact are prone to mutual wear and aging, resulting in poor contact between the static contact and the moving contact, leading to a poor grounding effect. At the same time, if the staff accidentally touches the operating rod, the grounding switch may no longer be connected to the ground, easily endangering the personal safety of the staff.

[0004] Therefore, an invention of a grounding switch mechanism for high and low voltage power distribution cabinets is proposed to solve the above problems. Summary of the Invention

[0009] When the rotating mechanism drives the supporting mechanism to swing towards the frame to the limit position, at this time the adjusting mechanism drives the moving contact to contact the static contact, and the rotating mechanism locks itself.

[0013] Preferably, a telescopic rod is slidably connected to one end of the adjusting plate close to the adjusting block. A plurality of positioning grooves corresponding to the telescopic rod are formed on the operating shaft.

[0019] Technical effects and advantages of the present invention:

[0020] 1.

When the connecting block swings to the extreme position, the moving contact gradually contacts with the static contact, and can avoid wear on the moving contact when the connecting block swings. Moreover, under the setting of the guide groove, even if the moving contact is worn, it can still be in close contact with the static contact, which not only improves the reliability of the contact between the static contact and the moving contact, but also reduces the damage to the static contact and the moving contact, reduces the problem of poor contact, and can also ensure the personal safety of the staff.

[0021] 2. The present invention can automatically lock the rotation of the operating shaft through the lateral movement of the adjustment plate and during the contact between the moving contact and the static contact, under the action of the telescopic rod, the limit block and the limit groove, thereby effectively reducing the problem of separation of the moving contact and the static contact caused by accidental touching of the operating shaft, improving the safety of the staff when repairing the circuit in the cabinet, and at the same time ensuring the reliability of the contact between the moving contact and the static contact, which can better ensure the personal safety of the staff.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] During the closing and opening processes of the grounding switch in the prior art, the moving contact 502 and the static contact 4 are prone to wear and aging, resulting in poor contact between the static contact 4 and the moving contact 502, and thus poor grounding effect. At the same time, if the operator accidentally touches the operating rod, the grounding switch may no longer be connected to the ground, which is likely to endanger the personal safety of the operator. To solve the above problems, this embodiment is specifically invented.

[0041] As Figures 1-8 shown, a grounding switch mechanism for a high and low voltage power distribution cabinet according to an embodiment of the present invention includes a cabinet body 1. A frame 2 is fixedly connected to the inner bottom of the cabinet body 1. A plurality of sensors 3 are fixedly connected to the frame 2. One end of each sensor 3 away from the frame 2 is fixedly connected to a static contact 4. The support mechanism 5 includes a connecting block 501 located on one side of the frame 2. Two moving contacts 502 are slidably connected to one end of the connecting block 501 close to the static contact 4. Each moving contact 502 can contact the static contact 4. A rotating mechanism 6 is fixedly arranged at one end of the frame 2 and is used to drive the support mechanism 5 to swing. The rotating mechanism 6 includes a plurality of brackets 601 fixedly connected to the frame 2. An operating shaft 602 is rotatably connected among the plurality of brackets 601. A plurality of support blocks 603 located on the corresponding brackets 601 are fixedly connected to the operating shaft 602.

[0042] The adjusting mechanism 7 is fixedly arranged between the supporting mechanism 5 and the rotating mechanism 6, and is used to adjust the positions of the two moving contacts 502. The adjusting mechanism 7 includes an adjusting block 701 fixedly connected to the supporting block 603, and a placement groove 702 with an opening facing the static contact 4 is provided on the adjusting block 701. The connecting block 501 is slidably connected to the adjusting block 701, and an adjusting plate 703 is slidably connected in the connecting block 501. The adjusting plate 703 is located in the placement groove 702, and two inclined guide grooves 704 are provided at one end of the adjusting plate 703 close to the static contact 4. Each moving contact 502 is fixedly connected to an adjusting rod 705 slidably connected to the connecting block 501, and one end of the adjusting rod 705 close to the adjusting block 701 is fixedly connected to a plug rod 706, and each plug rod 706 is fixedly connected to the connecting block 501. The rods 706 can be inserted into the corresponding guide grooves 704, a vertically extending guide groove 707 is provided on the adjustment plate 703, a longitudinally extending guide rod 708 is fixedly connected in the placement groove 702, the guide rod 708 is located in the guide groove 707 and can slide along the guide groove 707, a disc 711 mounted on the operating shaft 602 is fixedly connected to the bracket 601, an arc groove 712 is provided on the disc 711, a connecting rod 713 is provided on the connecting block 501, and a top rod 714 extending into the arc groove 712 is fixedly connected to the free end of the connecting rod 713. When the rotating mechanism 6 drives the supporting mechanism 5 to swing to the extreme position in the direction of the frame 2, the adjusting mechanism 7 drives the moving contact 502 to contact the static contact 4, and the rotating mechanism 6 locks itself.

[0043] A clearance groove 503 is provided at one end of the connecting block 501 close to the static contact 4, each moving contact 502 is located in the clearance groove 503, and the static contact 4 can extend into the clearance groove 503. A guide column 12 is commonly connected between two adjacent connecting blocks 501, and one of the guide columns 12 is connected to the ground through a wire 13. A circuit connection mechanism 14 is installed in the cabinet 1, and the circuit connection mechanism 14 is electrically connected to the static contact 4.

[0044] In use, when it is necessary to repair the interior of the cabinet body 1, it should be noted that the connection structure between the operating shaft 602 and the cabinet body 1 and the circuit connection mechanism 14 are both prior arts. The specific connection method will not be elaborated here. After opening the cabinet door of the cabinet body 1, the operating shaft 602 is manipulated, so that the operating shaft 602 drives the adjusting block 701 and the connecting block 501 to swing towards the frame 2 through the support block 603. Since the distance between the arc-shaped groove 712 and the center of the disc 711 gradually increases towards the frame 2, during the process of the adjusting block 701 swinging towards the frame 2, the connecting rod 713 drives the ejector rod 714 to slide along the arc-shaped groove 712, so that the connecting rod 713 drives the connecting block 501 to slide along the adjusting block 701 towards the direction close to the static contact 4. Since the guiding groove 707 is composed of a vertical section and an inclined section, the guiding rod 708 first slides along the vertical section of the guiding groove 707. When the guiding rod 708 slides to the inflection point between the vertical section and the inclined section of the guiding groove 707, after the guiding rod 708 slides from the vertical section of the guiding groove 707 into the inclined section, the guiding rod 708 drives the adjusting plate 703 to slide along the connecting block 501 through the guiding groove 707. Since the two inclined guiding grooves 704 form an eight shape, the adjusting plate 703 drives the two adjusting rods 705 to slide relative to each other along the relief groove 503 on the connecting block 501 through the insertion rod 706.

[0045] And during the process of the connecting block 501 swinging towards the frame 2 to the limit position, the static contact 4 gradually extends into the relief groove 503 of the connecting block 501. At the same time, the adjusting plate 703 drives the two moving contacts 502 to slide relative to each other through the insertion rod 706 and the two adjusting rods 705, so that the moving contacts 502 gradually contact the static contact 4. At this time, the moving contacts 502 can be in close contact with the static contact 4, so that the circuit connection mechanism 14 forms a loop with the ground through the static contact 4, the moving contacts 502, the guiding column 12 and the wire 13. At this time, the current in the cabinet body 1 can be guided to the ground, which can ensure the safety during the repair of the circuit in the cabinet body 1 and guarantee the personal safety of the staff. When it is necessary to disconnect the path to the ground, the above movement can be repeated in reverse at this time.

[0046] During the process of the static contact 4 sliding on the adjusting block 701 through the connecting block 501, the static contact 4 can gradually extend into the relief groove 503 of the connecting block 501 without contact. At this time, the friction of the static contact 4 by the connecting block 501 is reduced, and the two moving contacts 502 are driven to slide relative to each other through the adjusting plate 703 and the adjusting rod 705. When the connecting block 501 swings to the extreme position, the moving contact 502 gradually contacts the static contact 4, and at the same time, it can avoid wearing the moving contact 502 when the connecting block 501 swings. And under the setting of the guiding groove 707, even if the moving contact 502 is worn, it can still be in close contact with the static contact 4. This can not only improve the reliability of the contact between the static contact 4 and the moving contact 502, but also reduce the damage of the static contact 4 and the moving contact 502, reduce the occurrence of poor contact problems, and at the same time ensure the personal safety of the staff.

[0047] Embodiment 2

[0048] After the moving contact 502 swings to the specified position, when the staff accidentally touches the operating shaft 602, the moving contact 502 and the static contact 4 are separated from contact, resulting in the disconnection of the loop with the ground. At this time, potential safety hazards are likely to occur, which is not conducive to the safe construction of the staff. Therefore, based on the above embodiments, further improvements are made.

[0049] As Figures 6-11 shown, a limiting groove 604 is opened on one side of each bracket 601. A plurality of limiting blocks 605 corresponding to the positions of the limiting grooves 604 are slidably connected to the operating shaft 602. Each limiting block 605 can be inserted into the corresponding limiting groove 604. A plurality of sliding grooves 8 corresponding to the limiting blocks 605 are opened on the operating shaft 602. A sliding block 9 slidably connected to the sliding groove 8 is fixedly connected to one side of each limiting block 605 close to the operating shaft 602. A tension spring 10 is connected between the sliding block 9 and the sliding groove 8. A push rod 11 is coaxially and slidably connected inside the operating shaft 602. Each sliding block 9 is fixedly connected to the push rod 11. One end of the push rod 11 extends out of the operating shaft 602. One end of the adjusting plate 703 close to the adjusting block 701 is slidably connected to a telescopic rod 709. A plurality of positioning grooves 710 corresponding to the telescopic rod 709 are opened on the operating shaft 602. One end of each telescopic rod 709 close to the operating shaft 602 can be inserted into the corresponding positioning groove 710. The telescopic rod 709 is slidably connected to the support block 603 and the adjusting block 701.

[0050] During use, when the connecting block 501 slides along the adjusting block 701, the connecting block 501 drives the adjusting plate 703 to slide, causing the adjusting plate 703 to drive the telescopic rod 709 to slide in the direction of the static contact 4. Since the frictional force between the telescopic rod 709 and the support block 603 is greater than its own frictional force, the adjusting plate 703 drives the telescopic rod 709 to expand and contract. When the telescopic rod 709 expands and contracts to the limit position, at this time, under the action of the guiding rod 708 and the guiding groove 707, the adjusting plate 703 slides horizontally and slides in the direction of the static contact 4, and the telescopic rod 709 slides along the adjusting plate 703. Since the telescopic rod 709 expands and contracts to the limit state, at this time, the adjusting plate 703 drives the telescopic rod 709 to be pulled out from the positioning groove 710. Under the action of the tension spring 10, the tension spring 10 drives the limiting block 605 to slide along the operating shaft 602 through the slider 9 and the slideway 8, so that the limiting block 605 is inserted into the corresponding limiting groove 604, and at this time, the rotation of the operating shaft 602 is locked. When the operating shaft 602 is locked, when the operating shaft 602 is accidentally touched again, the reliability of the contact between the static contact 4 and the moving contact 502 can be ensured, a complete circuit can be formed, and at the same time, the personal safety of the staff can be avoided. When it is necessary to release the lock on the operating shaft 602, only need to push the push rod 11 to drive the limiting block 605 to be pulled out from the limiting groove 604 through the slider 9, and then rotate the operating shaft 602 again, and repeat the above movement in the reverse direction to release the contact state between the moving contact 502 and the static contact 4 and disconnect the ground circuit.

[0051] Through the horizontal movement of the adjusting plate 703 and during the contact process between the moving contact 502 and the static contact 4, under the action of the telescopic rod 709, the limiting block 605 and the limiting groove 604, the rotation of the operating shaft 602 can be automatically locked, which can effectively reduce the problem of the moving contact 502 and the static contact 4 being separated due to accidentally touching the operating shaft 602, improve the safety of the staff when overhauling the circuit in the cabinet 1, and at the same time can also ensure the reliability of the contact between the moving contact 502 and the static contact 4, and can better ensure the personal safety of the staff.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
