[0002] Insulators are extremely important special insulating controls in power systems. In terms of structural composition, they are mainly divided into porcelain insulators, glass insulators and composite insulators. The primary function of an insulator is insulation. It can withstand voltages of different voltage levels in a power system and separate live conductors from poles, towers or potential bodies such as the earth. For example, insulator strings in high-voltage transmission lines must withstand high voltages. In addition, insulators also play a mechanical support role and can withstand loads such as gravity, wind, and icing on the conductors. In terms of application scenarios, insulators are widely used in transmission lines, and the types and quantities of insulators used at different voltage levels are different.

The electric gear on the standby side is controlled to drive the two racks so that the two clamps clamp the wires. After the electric gear on the leakage side is controlled to drive the two racks so that the two clamps loosen the wires, the insulating medium on the leakage side and the box 2 are lowered into the detection chamber. The leakage of the insulator can be monitored during use. When leakage occurs, a new insulator can be quickly and automatically replaced, which is highly safe to use.

[0022] 2. After lowering the leaking insulating medium into the detection chamber, first clean the surface of the insulating medium, and then detect the resistance value between the upper and lower ends of the insulating medium.

The box body 1 is provided with a detection cavity 9 on both sides. The top of the detection cavity 9 is an open structure. The front and rear sides of the top of the detection cavity 9 are respectively connected with a door panel 10 through an electric hinge 30. Specifically, two door panels 10 are provided on the top of the detection cavity 9 on the same side in a double-opening manner. A telescopic rod 2 is provided at the bottom of the detection cavity 9. An insulating block 18 is fixedly connected to the telescopic end of the telescopic rod 2. An insulating medium 7 is fixedly connected to the top of the insulating block 18. A current sensor 4 is provided on the insulating block 18. A box body 11 is fixedly provided in the middle of the top of the insulating medium 7. The box body 11 1 is provided with an electric gear 12 in the middle, and the upper and lower sides of the electric gear 12 are horizontally meshed with racks 14, and the far ends of the two racks 14 pass through the left and right side walls of the box body 11 through avoidance holes 29 respectively, and the two avoidance holes 29 are respectively provided on both sides of the box body 11, and the far ends of the two racks 14 are respectively fixedly connected with claw arms 1 28 and claw arms 2 31, and claw arms 1 28 and claw arms 2 31 are respectively fixedly connected with two clamps 13, and the opposite surfaces of the clamps 13 are provided with wire clamping grooves, and the clamps 13 are slidably provided on the top outside the box body 11, and the control center 3 is electrically connected to the current sensor 4, the telescopic rod 1 2, the electric gear 12 and the electric hinge 30;

[0028] In order to facilitate understanding of the working principle of the present invention, the insulating medium 7 on the right side is regarded as being in use, and the insulating medium 7 on the left side is regarded as being in standby. It should be noted that when the insulating medium 7 on the left side is regarded as being in use and the insulating medium 7 on the right side is regarded as being in standby, the working principle is the same;

[0029] When using it for the first time, it is necessary to fix the box body 1 on a fixed object such as a pole tower, open the two door panels 10 on the right side, and drive the insulating medium 7 and the box body 2 11 on the right side to rise above the detection chamber 9 on the right side by controlling the telescopic rod 12 on the right side, and drive the upper rack 14 to move to the left by controlling the electric gear 12 on the right side, and drive the lower rack 14 to move to the right at the same time, so that the two racks 14 drive the two clamps 13 to move relatively close to each other through the claw arm 1 28 and the claw arm 2 31, respectively, and the two clamps 13 clamp the wires 15 into the two wire clamping grooves, and fix the wires 15 on the top of the box body 2 11 on the right side; in this state, the insulating medium 7 on the left side is located in the detection chamber 9 on the left side, and the top of the detection chamber 9 on the left side is closed by the two door panels 10 on the left side, which can prevent external dust and other dirt from adhering to the insulating medium 7 on the left side;

[0030] The present invention sets two groups of insulating medium 7, first uses the right group, and the left group is reserved. Since the vertical projection of the wire 15 is located in the middle of the two boxes 11 during installation, the current sensor 4 on the right side (in use) is first used to monitor the leakage current of the insulating medium 7 on the right side. The current sensor 4 transmits the leakage current to the control center 3. When the control center 3 determines that the leakage current is greater than the set threshold, the control center 3 controls the two electric hinges 30 on the left side to respectively drive the two door panels 10 on the left side to flip outward, open the top of the detection cavity 9 on the left side, and the control center 3 controls the telescopic rod 2 on the left side to drive the insulating medium 7 and the box on the left side through the insulating block 18.

After the wire 15 is released, the control center 3 controls the telescopic rod 1 2 on the right side to drive the insulating medium 7 and the box 11 on the right side to descend into the detection cavity 9. The present invention can monitor the leakage of the insulator during use, and when leakage occurs, it can quickly and automatically replace a new insulator, which is highly safe to use.

The left and right side walls of the box body 1 are provided with telescopic mechanisms, which are connected to two resistance detection probes 5. When the insulating medium 7 is lowered into the detection cavity 9, the telescopic mechanism can drive the two resistance detection probes 5 to move from the outside of the insulating medium 7 to contact the box body 2 11 and the insulating block 18 respectively. When the insulating medium 7 needs to be raised from the detection cavity 9, the telescopic mechanism needs to be used to drive the two resistance detection probes 5 to move to the outside of the insulating medium 7 to avoid interference with the insulating medium 7.

The control center 3 controls the telescopic mechanism on the right to drive the two resistance detection probes 5 to move from the outside of the insulating medium 7 to contact the box body 2 11 and the insulating block 18 respectively. The two resistance detection probes 5 are used to detect the resistance value between the upper and lower ends of the insulating medium 7 and transmit it to the control center 3. When the control center 3 determines that the detected resistance value is less than the set threshold value, it means that the leakage is caused by dirt attached to the surface of the replaced insulating medium 7, and no replacement is required.

[0039] A monitoring method for an insulator with a leakage monitoring function comprises the following steps:

[0040] The following steps also assume that the right side is in use and the left side is in standby mode.

[0041] S1. Use the current sensor 4 on the right to detect the leakage current of the insulating medium 7 on the right and transmit it to the control center 3. When the control center 3 determines that the leakage current is greater than the set threshold, the control center 3 controls the door panel 10 on the top of the left detection chamber 9 to open, and the control center 3 controls the insulating medium 7 on the left to rise to be flush with the insulating medium 7 on the right;

[0042] S2, after the control center 3 controls the two clamps 13 on the left to clamp the wire 15, the control center 3 controls the two clamps 13 on the right to release the wire 15;

[0044] S4, the control center 3 controls the electric turntable 20 to drive the insulating medium 7 on the right side to rotate through the telescopic rod 2, so that the bristles 16 on the right side sweep and clean the entire outer surface of the insulating medium 7 on the right side;

[0045] S5. After cleaning is completed, the control center 3 controls the bristles 16 on the right to turn back into the closed cavity 27 on the right, and then controls the electric sliding door on the right to close, and detects the resistance value between the box body 11 on the right and the insulating block 18 (equivalent to the resistance value of the insulating medium 7 on the right) and transmits it to the control center 3. When the control center 3 determines that the detected resistance value is less than the set threshold, it means that the leakage is caused by the dirt on the surface of the insulating medium 7. After cleaning, the leakage is eliminated and no replacement is required. The cleaned insulating medium 7 is retained in the detection cavity 9 as a backup. When the control center 3 determines that the resistance value is greater than the set threshold, it means that the insulating medium 7 is damaged. The positioning module 24 sends a fault location signal to the control center 3, and the control center 3 sends the location signal and the fault signal to the remote management platform through the communication module 23.

[0046] The present invention can monitor the leakage of the insulating medium 7 in use in real time, and after detecting the leakage, it can automatically replace the insulating medium 7, and then automatically clean the replaced insulating medium 7 and re-inspect it, and then notify the damaged insulating medium 7 to be replaced according to the re-inspection result.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
