Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of partial discharge monitoring, in particular to a 10-in-1 partial discharge monitoring system. Background Art
[0002] The PD 10-in-1 is an online PD monitoring sensor with multiple PD monitoring methods. When insulation defects exist inside switchgear and distribution equipment, PD will occur. By detecting PD, the insulation status of the switchgear can be effectively determined. This is when the PD 10-in-1 is needed.
[0003] When using a 10-in-1 PD device and PD ultrasonic waves to monitor partial discharge in switchgear, the sensor is generally magnetically attached to the switchgear door, and the sensor probe is aligned with the gap on the outside of the switchgear door. However, directly attaching the sensor to the door is unstable. When workers use excessive force when opening and closing the door, the sensor may slide downward relative to the door, causing the probe to misalign with the door gap after the door is closed, thereby reducing the stability of PD monitoring.

Detailed implementation mode
[0022] The following further elaborates on the present utility model in conjunction with the attached drawings.
[0023] Embodiment:
[0024] Referring to Figures 1 to 4 , the partial discharge 10-in-1 disclosed by the present utility model includes a housing 1. A probe 2 is fixedly connected to the upper half of one side of the housing 1. A first magnet 3 is fixedly connected to the lower half of the side wall of the housing 1. Two side grooves 4 are opened in the upper half of the side of the housing 1 close to the switch cabinet. The two side grooves 4 are respectively located on opposite sides of the probe 2. The upper half of the side groove 4 is rotatably connected with a rotating rod 5, and an adjusting part 6 is arranged on one side of the rotating rod 5.
[0025] A receiving groove 7 is opened in the side wall of the housing 1 below the side groove 4. The receiving groove 7 communicates with the corresponding side groove 4. A fixing block 8 is fixedly sleeved on the outer peripheral surface of the rotating rod 5. The bottom of the fixing block 8 is fixedly connected with a side plate 9, and the side plate 9 is located in the receiving groove 7.
[0026] In this embodiment, the side surface of the probe 2 is coplanar with the side wall of the housing 1. When the housing 1 is not installed, the side plate 9 is in a vertical state, and the fixing block 8 is completely located in the side groove 4 (as shown in Figure 2 ), at this time, transporting the device will not cause the side plate 9 to be impacted and bent, and it can also reduce the occupied space of the device.
[0027] When the device needs to be installed, the side plate 9 is adjusted through the adjusting part 6 so that the side plate 9 is in a horizontal state, and at this time, the side plate 9 is basically at the same height as the probe 2. The device is attached to the cabinet door of the switch cabinet. The side plate 9 is inserted into the gap at the top of the cabinet door, and the probe 2 is also directly aligned with the gap of the cabinet door. The first magnet 3 directly adsorbs the cabinet door, thereby fixing the device on the cabinet door. The housing 1 is subjected to both the magnetic adsorption force of the first magnet 3 and the supporting force between the cabinet door and the side plate 9, so the stability of the housing 1 is improved, and the housing 1 is prevented from sliding down when the cabinet door is opened and closed.
[0028] In a further preferred embodiment of the present utility model, as shown in Figure 3 and Figure 4 , the adjusting part 6 includes a worm gear 61 fixedly sleeved on the outer peripheral surface of the rotating rod 5. The inner top wall of the side groove 4 is rotatably connected with a worm 62. The worm 62 meshes with the corresponding worm gear 61, and the worm 62 rotates and extends below the housing 1.
[0029] In this embodiment, rotating the worm 62 drives the worm wheel 61 to rotate. The rotation of the worm wheel 61 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the fixed block 8 and the side plate 9 to rotate, so that the side plate 9 changes from the vertical state to the horizontal state.
[0030] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, a positioning plate 10 is fixedly connected to one side of the fixed block 8 close to the outside of the side groove 4, and a positioning groove 11 is provided on the inner top wall of the side groove 4. When the side plate 9 is in the horizontal state, the positioning plate 10 fits against the inner side wall of the positioning groove 11.
[0031] In this embodiment, in the initial state, the positioning plate 10 does not protrude from the side groove 4. When the fixed block 8 rotates, it drives the positioning plate 10 to rotate. And when the side plate 9 rotates to the horizontal state, the positioning plate 10 rotates into the inner side wall of the positioning groove 11 and fits against the inner side wall of the positioning groove 11, and the positioning plate 10 cannot rotate any further, thus reminding the staff that the adjustment is completed.
[0032] In a further preferred embodiment of the present utility model, as Figure 3 shown, when the side wall of the side plate 9 fits against the inner side wall of the receiving groove 7, the side plate 9 is completely located within the receiving groove 7.
[0033] In this embodiment, in the initial state, the side wall of the side plate 9 fits against the inner side wall of the receiving groove 7. Therefore, after the staff wants to retract the horizontally placed side plate 9 into the receiving groove 7, they rotate the worm 62 until the side plate 9 fits against the inner side wall of the receiving groove 7 and the side plate 9 can no longer move, which can remind the staff that the adjustment is completed. In the initial state, the side plate 9 is completely located within the receiving groove 7, preventing the side plate 9 from colliding with external components.
[0034] In a further preferred embodiment of the present utility model, as Figure 3 shown, when the side plate 9 is in the horizontal state, the fixed block 8 is completely located within the side groove 4.
[0035] In this embodiment, the fixed block 8 is always completely located within the side groove 4 during the rotation process, preventing the fixed block 8 from protruding from the side groove 4 so that the housing 1 cannot fit fully with the cabinet door.
[0036] In a further preferred embodiment of the present utility model, as Figure 1 shown, a knob 63 is fixedly connected to the bottom end of the worm 62, and the top surface of the knob 63 fits against the bottom surface of the housing 1.
[0037] In this embodiment, the setting of the knob 63 facilitates the staff to rotate the worm 62.
[0038] In a further preferred embodiment of the present utility model, as Figure 4 shown, a second magnet 12 is fixedly connected to one side of the side plate 9 close to the inner side wall of the receiving groove 7.
[0039] In this embodiment, when the side plate 9 is inserted into the gap of the cabinet door, the second magnet 12 is adsorbed on the top of the cabinet door, improving the stability of the side plate 9, and further improving the installation stability of the housing 1.
[0040] The implementation principle of the above embodiment is as follows:
[0041] In the initial state, the side plate 9 is in a vertical state and is completely located in the receiving groove 7, and the fixing block 8 is completely located in the side groove 4.
[0042] When installing this device, rotate the knob 63 to drive the worm 62 to rotate. The worm 62 drives the worm wheel 61 to rotate. The worm wheel 61 drives the rotating rod 5 to rotate. The rotating rod 5 drives the fixing block 8 and the side plate 9 to rotate, so that the side plate 9 changes from a vertical state to a horizontal state. Then insert the side plate 9 into the gap at the top of the cabinet door. The probe 2 is also directly aligned with the gap of the cabinet door, and the first magnet 3 directly adsorbs the cabinet door, thus fixing this device on the cabinet door, improving the installation stability of the housing 1, and further improving the partial discharge monitoring stability.
[0043] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
