Description

Technical Field

[0001] The present invention relates to the technical field of power switch cabinet maintenance equipment, and in particular to an electric auxiliary device for a baffle used in a nuclear phase of a 10kV switch cabinet. Background Art

[0002] During power system operation, after a substation is commissioned or renovated, phase verification is required on the newly commissioned / renovated equipment to verify the consistency of the installed phase sequence with the designed phase sequence. The phase verification process for a 10kV switchgear is as follows: 1) Workers use an insulating rod to pull open the switchgear's movable baffle, exposing the live static contacts; 2) Workers then use an instrument to verify the consistency of the static contacts' actual phase sequence with the switchgear's designed phase sequence. This process requires workers to reach inside the switchgear and move the baffle lever to open it. The baffle is often tilted, requiring multiple adjustments during the phase verification process. Furthermore, the safe distance between live parts and workers cannot be guaranteed.

[0003] In response to the problems involved in opening the isolation baffles of the above-mentioned 10kV switchgear, there are also some auxiliary devices in the prior art that are operated by hand-cranking or pushing. The auxiliary devices avoid direct contact between the operator and the switchgear and ensure a safe distance between the live parts and the staff. However, the applicability of such auxiliary devices in the prior art that are operated by hand-cranking or pushing is generally small, and is only applicable to switchgear of a single size.

[0032] Example 1:

[0033] See Figure 1 、 Figure 2 As shown in the figure, the first embodiment of the present invention proposes an electric auxiliary device for a baffle of a 10kV switch cabinet nuclear phase, comprising a main box 1 and an electric push rod box 4. The main box 1 is provided with a power module 8 and a horizontal push module 2. The driving direction of the horizontal push module 2 is toward the side of the electric push rod box 4. The end of the horizontal push module 2 is fixedly connected to the electric push rod box 4 through a quick-release connection structure to adjust the distance between the electric push rod box 4 and the main box 1 in the width direction. When the horizontal push module 2 performs a pushing stroke, the electric push rod box 4 moves away from the main box 1 in the width direction ( Figure 2 It can be extended in the left direction to adapt to switch cabinets of different widths. Figure 1As shown, the interior of the electric push rod box 4 and the interior of the main box 1 are respectively provided with a driving direction perpendicular to the driving direction of the horizontal pushing module 2 at one end away from the electric push rod box 4. The pushing module 5 is connected to a longitudinal module 6 with an adjustable height on the driving end located outside the box body for controlling the opening and closing of the isolation baffle of the switch cabinet. When it is necessary to control the opening and closing of the isolation baffle of the nuclear phase switch cabinet, the width of the device is first adjusted by the horizontal pushing module 2, that is, the electric push rod box 4 is pushed away from the main box 1 so that the width between the left and right ends of the main box 1 and the electric push rod box 4 is suitable for the current width size of the switch cabinet, and then the two pushing modules 5 are synchronously started. The pushing modules 5 started synchronously on both sides respectively push the longitudinal modules 6 connected to their respective driving ends toward the longitudinal direction of the device so that the longitudinal modules 6 reach the button on the isolation baffle of the switch cabinet. As the pushing module 5 is further pushed, the isolation baffle of the switch cabinet is pushed to open. After the pushing module 5 withdraws the pushing stroke, the longitudinal module 6 returns to the initial position of the side wall of the main box 1, and the isolation baffle of the switch cabinet is reset and closed. Since the button heights on the isolation baffles of different switch cabinets are different, in order to be applicable to switch cabinets with different button heights, the longitudinal module 6 of the present invention also has a height-adjustable function. According to the different button heights, the longitudinal module 6 can be height-adjusted on the push module 5 to be applicable to the opening and closing control of the isolation baffles of switch cabinets with different button heights. Through the control of the horizontal push module 2, the push module 5 and the longitudinal module 6, the electric auxiliary device for the core phase baffle of the 10kV switch cabinet of the present invention can avoid direct contact between the operator and the 10kV switch cabinet, and ensure a safe distance from the live device. By replacing manual operation with electric operation, the working efficiency of the opening operation of the isolation baffle of the 10kV switch cabinet is improved, so that the electric auxiliary device for the core phase baffle of the 10kV switch cabinet of the present invention has high applicability and safety for opening various types of 10kV switch cabinet isolation baffles.

[0034] Further, if Figure 3As shown, in a preferred embodiment of the present invention, the horizontal pushing module 2 includes a turbine motor 21, a screw 22, two screw fixing seats 23, a screw sleeve seat 24, a linkage arm 25, two push rods 26, and a coupling 29. Specifically, the turbine motor 21 is electrically connected to the power module 8, and the motor shaft of the turbine motor 21 is transmission-connected to the screw 22 through the coupling 29. The two ends of the screw 22 are rotatably connected to the screw fixing seats 23 at both ends. The screw sleeve seat 24 is threadedly connected to the screw 22, and the linkage arm 25 is fixed to the screw sleeve seat 24 and is arranged perpendicular to the screw 22. A push rod 26 is fixed to each end of the linkage arm 25, and the end of the push rod 26 passes through the push rod hole 12 on the side end plate of the main box 1 and is led out to the outside of the main box 1, and is quickly connected to the opposite side end plate of the external electric push rod box 4 through a quick-release connection structure. After the turbine motor 21 rotates a set angular displacement, the lead screw 22 rotates and drives the lead screw sliding sleeve 24 to carry the linkage arm 25 and the push rod 26 as a whole to complete a corresponding linear stroke, thereby realizing the horizontal drive of the electric push rod box 4.

[0035] like Figure 3 and Figure 4 As shown, push rod fixing blocks 251 are provided on the upper surfaces of both ends of the linkage arm 25, and the front ends of the push rods 26 are fixed on the push rod fixing blocks 251. When the linkage arm 25 moves, it can drive the push rods 26 at both ends to synchronously complete the pushing action. In order to make the linkage arm 25 and the push rod 26 as a whole more stable in performing the pushing action, the main chassis 1 is provided with a pushing stabilization mechanism at both ends of the corresponding linkage arm 25 for stabilizing the linkage arm 25. Specifically, as shown in FIG. Figure 3 As shown, the pushing and stabilizing mechanism includes two parallel guide rods 27 provided in the main chassis 1. The two guide rods 27 are respectively arranged on the left and right sides of the lead screw 22 and are respectively parallel to the lead screw 22. Specifically, as Figure 3 As shown, a guide rod 27 on the same side is arranged parallel to and below the push rod 26 on that side. The two ends of the guide rod 27 are respectively fixed by two guide rod support seats 271 provided in the main chassis 1. Among them, a guide rod slide 28 is slidably sleeved on the guide rod 27. The guide rod slide 28 is fixedly connected to the end of the linkage arm 25. The guiding effect provided by the guide rods 27 on both sides can provide stable support for the pushing action of the linkage arm 25 and the push rod 26.

[0036] In order to facilitate the movement of the lead screw sliding sleeve seat 24 and the guide rod sliding seat 28 in the main box 1, as shown in FIG. Figure 3As shown, the bottom of the main case 1 is provided with raising blocks 11 at the positions corresponding to the screw fixing seat 23 and the guide rod support seat 271, wherein the screw fixing seat 23 and the guide rod support seat 271 are respectively fixed on the corresponding raising blocks 11, so that the screw sliding seat 24 and the guide rod sliding seat 28 can have a safe suspended distance from the bottom of the main case 1, thereby avoiding friction between the screw sliding seat 24 and the guide rod sliding seat 28 and the bottom of the main case 1 when moving.

[0037] Further, if Figure 5 As shown, in a preferred embodiment of the present invention, the longitudinal module includes a height adjustment seat 61 and an actuator 62 provided on the height adjustment seat 61 for pushing the isolation baffle button in the switch cabinet. Particularly, a fixing sleeve 611 connected to the driving end of the pushing module 5 is formed on the height adjustment seat 61, and the actuator 62 includes two "L"-shaped push claws 621 symmetrically arranged up and down, and the "L"-shaped push claws 621 are adjustably fixed on the height adjustment seat 61 through a height adjustment structure. When applied to isolation baffles of switch cabinets with different button heights, the position of the actuator 62 on the height adjustment seat 61 can be adjusted accordingly to lower the installation position of the actuator 62 on the height adjustment seat 61, thereby adapting to isolation baffles of switch cabinets with different button heights. At the same time, the actuator 62 of the present invention can also adapt to buttons of different sizes by adjusting the relative distance between the two "L"-shaped push claws 621. Specifically, as Figure 5 As shown, the height adjustment structure includes a vertical elongated hole 612 formed on the height adjustment base 61, and a handle screw 622 adapted to fit into the vertical elongated hole 612 is formed on the vertical side plate of the "L"-shaped push claw 621. The handle screw 622 is fastened to the vertical side plate of the "L"-shaped push claw 621 via a handle nut 63. When the height needs to be adjusted, the handle nut 63 can be loosened, and then the installation height of the handle screw 622 can be adjusted. After moving to the corresponding adjustment height, the "L"-shaped push claw 621 can be fixed by tightening the handle nut 63, making height adjustment convenient.

[0038] The 10kV switch cabinet core phase baffle electric auxiliary device provided in the embodiment of the present invention is suitable for 10kV switch cabinets with relatively small width. The electric push rod box 4 is fixedly connected to the end of the push rod 26 of the horizontal push module 2 through a quick-release connection structure. As a preferred embodiment of the present invention, Figure 1 and Figure 10As shown, the quick-release connection structure includes a width-adjusting push plate 3 and an "L"-shaped bayonet 31 formed on the upper and lower edges of the side end plate of the box body, wherein a push plate assembly groove 311 is formed between the "L"-shaped bayonet 31 and the surface of the side end plate, and the upper and lower edges of the width-adjusting push plate 3 are snapped into the "L"-shaped bayonet 31. In the electric auxiliary device for the nuclear phase baffle of the 10kV switchgear in Example 1, the "L"-shaped bayonet 31 of the quick-release connection structure is formed on the side end plate of the electric push rod box 4 relative to the main box 1. The width-adjusting push plate 3 is inserted in parallel from the lateral open port of the push plate assembly groove 311, and the upper and lower edges of the width-adjusting push plate 3 are inserted into the push plate assembly groove 311, so that the width-adjusting push plate 3 is locked and connected to the electric push rod box 4. The push rod 26 on the horizontal push module 2 is fixedly connected to the width-adjusting push plate 3. When disassembly or assembly is required, the electric push rod box 4 can be translated laterally to allow the width-adjusting push plate 3 to escape from the push plate assembly groove 311 .

[0039] Furthermore, in a preferred embodiment of the present invention, it also includes an anti-error module for ensuring the safety of operation and maintenance personnel, and the anti-error module includes a limit switch 72, a buzzer alarm 73, an infrared transmitter 71 and an infrared receiver 7, wherein the limit switch 72 is provided at a position where the main box 1 is opposite to the longitudinal module 6, the infrared transmitter 71 is provided on the electric push rod box 4, and the infrared receiver 7 is provided on the main box 1, corresponding to the infrared transmitter 71. When the operation and maintenance personnel operate the device of the present invention and mistakenly extend their elbows or bodies into the switch cabinet, the infrared transmitter 71 and the infrared receiver 7 are triggered, and the controller controls the pushing module 5 to retreat, while the buzzer alarm 73 generates an alarm prompt. When the pushing module 5 retreats to the limit switch 72, the isolation baffle of the switch cabinet is closed, the pushing module 5 stops running, and the buzzer alarm 73 stops sounding. The present invention can monitor the safe distance between the operator and the switch cabinet by infrared monitoring through the anti-error module, close the isolation baffle of the switch cabinet in time, and greatly reduce the risk of electric shock. As a preferred embodiment, in an embodiment of the present invention, if Figure 5 As shown, the pushing module 5 is an electric push rod 51 , and the telescopic push rod of the electric push rod 51 passes through the side wall of the main box 1 and is fixedly connected to the fixed sleeve 611 of the height adjustment seat 61 .

[0040] Example 2:

[0041] See Figures 6 to 9As shown in the figure, the second embodiment of the present invention proposes an electric auxiliary device for a baffle of a 10kV switch cabinet core phase. In the second embodiment, a width extension box 9 is added to the first embodiment. The width extension box 9 is arranged between the main box 1 and the electric push rod box 4. The end of the horizontal push module 2 in the main box 1 is fixedly connected to the width extension box 9 through a quick-release connection structure, which is used to adjust the distance between the width extension box 9 and the main box 1 in the width direction. The side end plate of the width extension box 9 is detachably connected to the opposite side end plate of the electric push rod box 4 through a quick-release connection structure. In the second embodiment, the "L"-shaped bayonet 31 on the quick-release connection structure between the main box 1 and the width extension box 9 is formed on the side end plate of the width extension box 9 relative to the main box 1, and the width adjustment push plate 3 of the quick-release connection structure is locked and connected to the "L"-shaped bayonet 31 on the width extension box 9. The push rod 26 on the horizontal push module 2 is fixedly connected to the width adjustment push plate 3 that is locked and connected to the width adjustment push plate 3.

Through the quick-release connection structures at these two locations, the electric push rod box 4, the width extension box 9 and the main box 1 can be quickly and sequentially assembled.

[0042] In the second embodiment of the present invention, the width extension box 9 is used to make up for the width of the device. For 10kV switch cabinets with a relatively large width, the width extension box 9 is locked and connected to the electric push rod box 4 and the main box 1 respectively, which can increase the width of the device, reduce the width adjustment time, and improve the operating efficiency. The 10kV switch cabinet core phase baffle electric auxiliary device provided in the second embodiment of the present invention is suitable for 10kV switch cabinets with a relatively large width.
