Description

Technical Field

[0001] This utility model specifically relates to the field of lower disconnect switch break-in technology, and more specifically to an automatic lower disconnect switch break-in device. Background Technology

[0002] A down-disconnecting switch is a type of disconnecting switch installed in a specific location within a power system. Its core function is to create a clear electrical disconnect point in the circuit, ensuring the safety of personnel and equipment during maintenance and repair operations. A disconnecting switch is a switching device with no or very weak arc-extinguishing capability, primarily used to isolate power sources in a power system, creating a clear disconnect point between the equipment requiring maintenance and live parts. The "down" in "down-disconnecting switch" usually refers to its installation position being below a certain electrical device (such as a circuit breaker or transformer), or downstream in the circuit topology, used to isolate the circuit or load below it.

[0003] After the lower disconnector is assembled, due to accumulated errors in parts and other reasons, the grounding may not be fully engaged or disengaged. It is necessary to manually rotate the engagement and disengagement shaft and repeatedly run it 50-60 times to confirm that there is no jamming or dead spot when engaging or disengaging. This is very labor-intensive and the overtravel data of engagement and disengagement is inaccurate. Utility Model Content

[0004] The purpose of this invention is to provide an automatic break-in device for a lower disconnect switch. In this device, the lower disconnect switch is placed in a designated position, and the device connects the lower disconnect switch to a spring mechanism. Then, the power supply is connected, and the device automatically performs actions such as grounding and grounding opening, and can simultaneously detect some necessary data to solve the problems mentioned above in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic break-in device for a lower disconnect switch includes a frame; the frame is U-shaped; a fixing plate is fixedly installed inside one end of the frame; an electric pusher cylinder is fixedly installed on the fixing plate; the push rod of the electric pusher cylinder passes through the fixing plate and is fixedly installed on the pusher plate.

[0007] The other end of the frame is provided with a box, and an operating mechanism is installed on the side wall of the box; a lifting and translating assembly is also installed inside the frame; the lifting and translating assembly includes a support frame that is fixedly installed with the frame.

[0008] As a further technical solution of this utility model, two symmetrical slide rails are fixedly installed on the top crossbeam of the support frame; a movable plate is slidably installed on the slide rails via a slider; and multiple sliding columns are slidably installed on the movable plate.

[0009] As a further technical solution of this utility model, the top of the sliding column is fixedly installed with the lifting plate; the bottom of the lifting plate is fixedly installed with the cylinder push rod; and the cylinder is fixedly installed at the bottom of the moving plate.

[0010] As a further technical solution of this utility model, the top two ends of the lifting plate are provided with symmetrical sliding rods through fixing blocks; the sliding rods are movably installed with the carrier plate through connecting blocks;

[0011] As a further technical solution of this utility model, side plates are fixedly installed at both ends of the top of the carrier plate; a U-shaped groove is opened on the side plate; the side plate and the U-shaped groove cooperate with the two ends of the lower disconnect switch;

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, the lower disconnect switch is placed on the carrier plate by a robotic arm gripper, and the two ends of the lower disconnect switch are matched with the U-shaped grooves opened on the side plate to effectively ensure the stability of the lower disconnect switch. After the lower disconnect switch is placed, the robotic arm transmits a signal to the controller, and the cylinder push rod drives the moving plate to move upward, so that the lower disconnect switch is coaxial with the dynamic seal in the operating mechanism. Then, the carrier plate is manually pushed to connect the lower disconnect switch and the dynamic seal.

[0014] This utility model uses a controller to enable an electric pusher cylinder to move a push plate forward, thereby effectively fixing the lower disconnect switch. At this time, the cylinder retracts, separating the side plate and carrier plate from the lower disconnect switch, and then closing the soundproof protective cover. The controller enables the operating mechanism to automatically break in the lower disconnect switch.

[0015] In this invention, during the break-in process, the circuit breaker mechanism drives the grounding and closing of the lower disconnector switch. The controller effectively monitors the break-in time and number of cycles. After the break-in is completed, the soundproof cover automatically opens, and the cylinder drives the side plate and the carrier plate to rise, lifting the lower disconnector switch. At this time, the electric pusher cylinder drives the push plate to move backward. The lower disconnector switch is separated from the operating mechanism by manually pulling the moving plate, and then the lower disconnector switch is removed by the robotic arm gripper.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 In this embodiment of the utility model, the automatic break-in equipment for the lower disconnect switch includes a frame 1; the frame 1 is U-shaped; wherein, a fixing plate 2 is fixedly installed inside one end of the frame 1; an electric push cylinder 7 is fixedly installed on the fixing plate 2; the push rod of the electric push cylinder 7 passes through the fixing plate 2 and a push plate 6 is fixedly installed thereon.

[0025] The other end of the frame 1 is provided with a box 3, and an operating mechanism 8 is installed on the side wall of the box 3; a lifting and translating assembly 5 is also installed inside the frame 1; the lifting and translating assembly 5 includes a support frame 50 fixedly installed with the frame 1.

After the lower disconnect switch 4 is placed, the robotic arm transmits the signal to the controller, and the moving plate 57 is moved upward by the push rod of the cylinder 51, so that the lower disconnect switch 4 is coaxial with the dynamic seal in the operating mechanism 8. Then, the carrier plate 55 is manually pushed to connect the lower disconnect switch 4 with the dynamic seal.

[0027] In this embodiment, two symmetrical slide rails 53 are fixedly installed on the top crossbeam of the support frame 50; a movable plate 57 is slidably installed on the slide rails 53 via a slider 56; and multiple sliding columns 59 are slidably installed on the movable plate 57.

[0029] By adopting the above technical solution, the electric pusher cylinder 7 drives the push plate 6 to move forward through the controller, so that the push plate 6 can effectively fix the lower disconnect switch 4. At this time, the cylinder 51 retracts, so that the side plate 52 and the carrier plate 55 are separated from the lower disconnect switch 4. Then the soundproof protective cover is closed, and the operating mechanism 8 is automatically run-in to the lower disconnect switch 4 through the controller.

[0030] Furthermore, the top two ends of the lifting plate 510 are provided with symmetrical sliding rods 58 via fixing blocks; the sliding rods 58 are movably installed with the carrier plate 55 via connecting blocks.

[0031] In this embodiment, side plates 52 are fixedly installed at both ends of the top of the carrier plate 55; a U-shaped groove 54 is provided on the side plate 52; the side plate 52 and the U-shaped groove 54 cooperate with the two ends of the lower isolating switch 4.

[0032] By adopting the above technical solution, during the break-in process, the circuit breaker mechanism is used to drive the grounding of the lower disconnector switch 4. The controller effectively monitors the break-in time and number of times. After the break-in is completed, the soundproof cover opens automatically, and the cylinder 51 drives the side plate 52 and the carrier plate 55 to rise, thereby lifting the lower disconnector switch 4.

[0033] The working principle of this utility model is as follows: In use, the lower disconnect switch 4 is placed on the carrier plate 55 by the gripper of the robotic arm, and the two ends of the lower disconnect switch 4 are matched with the U-shaped groove 54 opened on the side plate 52 to effectively ensure the stability of the lower disconnect switch 4. After the lower disconnect switch 4 is placed, the robotic arm transmits the signal to the controller, and the moving plate 57 is moved upward by the push rod of the cylinder 51, so that the lower disconnect switch 4 is coaxial with the dynamic seal in the operating mechanism 8. Then, the carrier plate 55 is manually pushed to connect the lower disconnect switch 4 with the dynamic seal.

[0034] The controller enables the electric push cylinder 7 to move the push plate 6 forward, so that the push plate 6 can effectively fix the lower disconnect switch 4. At this time, the cylinder 51 retracts, so that the side plate 52 and the carrier plate 55 are separated from the lower disconnect switch 4. Then the soundproof protective cover is closed. The controller enables the operating mechanism 8 to automatically break in the lower disconnect switch 4.

[0035] During the break-in process, the circuit breaker mechanism is used to open and close the grounding of the lower disconnector switch 4. The controller effectively monitors the break-in time and number of times. After the break-in is completed, the soundproof cover opens automatically, and the cylinder 51 drives the side plate 52 and the carrier plate 55 to lift the lower disconnector switch 4. At this time, the electric push cylinder 7 drives the push plate 6 to move backward. The lower disconnector switch 4 is separated from the operating mechanism 8 by manually pulling the moving plate 57. Then, the lower disconnector switch 4 is taken out by the robotic arm gripper.
