Description

Technical Field

[0001] This utility model relates to the field of power equipment installation and testing technology, specifically to a busbar power supply device. Background Technology

[0002] In power systems, substations play a crucial role in voltage transformation, power reception, and distribution. Internally, power transmission occurs via busbars. During routine operation and maintenance, external connectors are typically required for live-line testing and repair of substations or high-voltage switchgear.

[0003] Currently, these connectors on the market pose significant safety hazards during installation, especially in situations requiring live-line work. Traditional connectors mostly require operators to use both hands for installation and tightening, which forces their hands to be very close to the live busbar, greatly increasing the risk of electric shock.

[0004] Therefore, there is an urgent need for a connection device that can enable rapid and safe live installation to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model The purpose of this utility model is to solve the technical problems existing in the prior art and provide a busbar power supply device. It can achieve "single-hand push-in" safe pre-fixation of the busbar power supply device through the clever cooperation of elastic clamping claws and front inclined guide surface, fundamentally solving the risk of electric shock when the hand is close to the busbar during live installation.

[0006] 2. Technical Solution To solve the above problems, the technical solution provided by this utility model is as follows: A power supply device for a busbar includes a fixed base, on which a piercing claw and a receiving rod are movably connected. The receiving rod is used to push out the piercing claw. Both sides of the piercing claw are provided with clamping claws, which are connected to the fixed base. At least one of the clamping claws is connected to the fixed base through an elastic mechanism, and at least one of the clamping claws has an inclined guide surface at its front end.

[0007] Preferably, the elastic mechanism includes a guide rod and a spring. One end of the guide rod is fixedly connected to the clamping claw, and the other end is movably inserted inside the fixed base. The spring is used to drive the guide rod to return to its original position inward.

[0008] Preferably, the spring is sleeved on the guide rod and housed in the fixed seat, with one end of the spring fixed and the other end abutting against a limiting block fixedly disposed on the guide rod.

[0009] Preferably, the fixing seat has a cavity, and a connecting block is detachably connected to the cavity, with the guide rod and spring housed within the connecting block.

[0010] Preferably, a nut is connected to the end of the guide rod, and the nut abuts against the end face of the clamping claw.

[0011] Preferably, one end of the receiving rod is threadedly connected to the fixed base; the piercing claw is mounted on a piercing claw base, the piercing claw base is movably connected to the fixed base, and abuts against the end of the receiving rod that extends into the fixed base.

[0012] Preferably, the other end of the power connection pole is a power connection terminal for connecting external equipment.

[0013] 3. Beneficial effects Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention discloses a busbar power supply device, which fundamentally solves the problems of dangerous and inefficient live-line installation operations in existing technologies. The device achieves a revolutionary "one-handed pre-fixation" operation through its unique structural design: at least one of its symmetrically arranged clamping claws is connected by an elastic mechanism, and its front end has a beveled guide surface. During installation, the operator only needs to push the device towards the busbar with one hand. The busbar will automatically open the claws with the help of the beveled guide surface and slide into the claws, completing a quick and reliable pre-fixation under the action of a spring, keeping the operator's hand away from the live conductor. After pre-fixation, the user can safely screw on the connecting rod to drive the piercing claw to penetrate the busbar and complete the power supply. The entire process transforms the high-risk "two-handed live-line precision operation" into a safe two-step operation of "one-handed pre-fixation + remote piercing," greatly improving operational safety and convenience.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The terms "first" and "second" in this utility model do not represent specific quantities or orders, but are merely used to distinguish names.

[0022] like Figures 1 to 3 As shown, a busbar power supply device in this embodiment mainly includes a fixed base 10, a piercing claw 20, a power receiving pole 30, and a pair of clamping claws 40. The pair of clamping claws 40 are used to clamp the two sides of the busbar, which is not the traditional clamping on both sides of the busbar.

[0023] In this embodiment, the fixed base 10 serves as the main structure, with an internal cavity 60. The piercing claw 20 is fixedly mounted on a piercing claw base 201, which is movably disposed within the channel at the front of the fixed base 10. One end of the connecting rod 30 is threaded into the inner wall of the channel at the rear of the fixed base 10, and its end abuts against the tail of the piercing claw base 201. By screwing the connecting rod 30, the piercing claw base 201 and the piercing claw 20 can be pushed forward. The other end of the connecting rod 30 is a power receiving end, used to connect external cables or measuring equipment. To ensure operational safety, the connecting rod 30 is preferably covered with an insulating sleeve (not shown in the figure).

[0024] In this embodiment, the two clamping claws 40 are symmetrically arranged on both sides of the puncture claw 20. In this embodiment, both clamping claws 40 are connected to the fixed base 10 through the elastic mechanism 50, so that they can elastically open and close relative to the fixed base 10. Each clamping claw 40 includes a clamping plate 401 and an anti-dislodgement part 402 formed on the inner side of the clamping plate 401. The front end face of the anti-dislodgement part 402 is constructed as an inclined guide surface 40a, which is arranged obliquely inward toward the puncture claw 20.

[0025] Specifically, the elastic mechanism 50 includes a guide rod 501 and a spring 502. One end of the guide rod 501 (e.g., a bolt) is fixedly connected to the clamping claw 40 via a nut 504. The clamping claw 40 has a groove for the nut 504 to be inserted to ensure a smooth connection. The other end of the guide rod 501 passes through a through hole in the connecting block 70. The spring 502 is sleeved on the guide rod 501 and housed inside the connecting block 70. A limiting block 503 (e.g., the head of a bolt) is fixedly provided on the guide rod 501. One end of the spring 502 abuts against the limiting block 503, and the other end abuts against the inner end face of the connecting block 70. When the clamping claw 40 is subjected to an outward force, it will drive the guide rod 501 to move and compress the spring 502. The restoring force of the spring 502 will drive the clamping claw 40 to return to its original position.

[0026] For ease of assembly and maintenance, a connecting block 70 is detachably connected inside the cavity 60 of the fixed base 10. The aforementioned elastic mechanism 50 (guide rod 501, spring 502, etc.) is pre-installed in the connecting block 70 to form a modular component, which is then installed into the cavity 60 of the fixed base 10 and fixed by means of threaded connection.

[0027] To ensure the stability of the movement of the gripping jaws 40, each elastic gripping jaw 40 is preferably connected to the fixed base 10 through two symmetrically arranged elastic mechanisms 50.

[0028] Working principle and installation process: The core advantage of this invention lies in its "pre-fixing" mechanism, which enables safe one-handed installation while the device is powered on. The process is as follows: Pre-fixing stage: The operator holds the insulated part of the device and brings it close to the busbar. First, the anti-detachment part 402 of one of the clamping claws 40 is moved past one side of the busbar. Then, the operator continues forward and pushes the device with a little force, so that the other side of the busbar contacts and presses against the inclined guide surface 40a of the other clamping claw 40. Under the action of the inclined guide surface 40a, the force applied by the busbar is converted into a lateral component force that causes the clamping claw 40 to open outward, compressing the spring 502, thereby allowing the busbar to slide smoothly between the two clamping claws 40. Once the busbar is fully inserted, the compressed spring 502 immediately drives the clamping claw 40 to reset, using the anti-detachment part 402 to hold the busbar from both sides, achieving initial fixation of the device. This process can be completed with a single push with one hand, without the need for delicate hand operations near the busbar.

[0029] Puncture and Connection Stage: After the device is reliably pre-secured to the busbar, there is no longer a risk of direct contact between the operator and the energized busbar. At this point, use an insulated operating rod or wrench to tighten the connection rod 30. Driven by the threads, the connection rod 30 advances forward, pushing the puncture claw base 201 and puncture claw 20 forward, causing them to puncture the oxide layer on the surface of the busbar and engage tightly, thereby establishing a low-resistance, high-reliability electrical connection. Finally, connect the external equipment to the connection terminal to begin power extraction or supply operations.

[0030] In another embodiment, only one clamping claw 40 can be connected to the fixed base 10 via the elastic mechanism 50, while the other clamping claw 40 is fixedly connected to the fixed base 10. In this case, the inclined guide surface 40a should be located at the front end of the fixedly connected clamping claw 40. The installation process is similar to that in Embodiment 1: first, the elastically connected clamping claw 40 is moved over the busbar side, and then the device is pushed so that the busbar presses against the inclined guide surface 40a on the fixed clamping claw 40. Since the clamping claw 40 is fixed, the reaction force will cause the entire device to deflect, thereby forcing the elastically connected clamping claw 40 to open outward. After the busbar enters, the elastically connected clamping claw 40 is reset under the action of the spring force, completing the pre-fixation. This solution can also achieve the purpose of the present invention.

[0031] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
