[0002] Insulation monitoring instruments, also known as insulation testers, insulation meters, DC screen insulation meters, photovoltaic insulation meters, and electric vehicle insulation meters, have a power supply range of 90-300VDC or 85-250VAC. They are compatible with 24V, 48V, 110V, and 220V systems. The existing detection methods mainly include the bridge balance principle and the low-frequency detection principle. In the field of power system maintenance, insulation monitoring instruments are commonly used to monitor the insulation of lines.

[0003] Patent application number CN202221262512.1 discloses an online insulation monitoring device for a power system, including a housing. Inside the housing, a monitoring instrument body is disposed. Side plates are fixedly connected to both the upper and lower ends of the monitoring instrument body. A pressure plate is disposed on the front side of the side plate. A spring is fixedly connected to the front end of the pressure plate, and the front end of the spring is fixedly connected to the housing. A wire is fixedly connected to the left end of the monitoring instrument body. A side cover is disposed on the left end of the housing, and the right end of the side cover abuts against the left end of the monitoring instrument body. A circular hole is disposed in the middle of the side cover.

[0004] When using this structure, the monitor body is inserted into the housing, and the side plate is inserted into the rear end of the pressure plate, so that the monitor body is completely submerged in the housing.

[0041] 3. This invention causes the shaft assembly to shift, driving the cable harness arc component to rotate along the axis at the connection point between the cable harness arc component and the support bracket component. This causes the two cable harness arc components on the support bracket component to move closer to each other, clamping the cable and ensuring the stability between the device and the cable. This prevents the device from becoming loose during insulation monitoring. The cable harness assembly shifts, allowing it to pull the cable and adjust the tightness of the cable harness assembly after the cable is bundled, thus improving the convenience and versatility of the device during use.

[0042] 4. In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of various structures, the extension rod, support plate, and universal ball seat can be unfolded to support the device. This allows for multi-angle adjustment of the support points during installation, improving the versatility and convenience of subsequent insulation monitoring. It also facilitates multi-angle adjustment of the cable clamping assembly when bundling cables, ensuring the stability between the device and the cable and preventing slackness during insulation monitoring. Adjusting the tightness of the cable clamping assembly after cable bundling enhances the convenience and versatility of the device during use. It allows for appropriate fine-tuning according to the complex environment of the line laying, easily realizing the function of wire bundling monitoring during insulation testing. It is convenient to use and has good practicality. Attached Figure Description

[0087] Preferably, the cross-sectional shape of the wire harness arc member 312 is set to arc shape, and the two wire harness arc members 312 are arranged opposite to each other, and the wire harness arc member 312 is provided with a rubber sleeve for anti-slip.

[0088] According to the above structure, when using this invention, the operator first installs the invention in the designated location. During use, the operator first activates the first hydraulic push rod 103, driving the first connecting rod 101 to rotate along the axis connecting the first connecting rod 101 and the support frame 1, thus unfolding the first connecting rod 101. Then, the operator activates the second hydraulic push rod 104, driving the second connecting rod 102 to rotate along the connection between the second connecting rod 102 and the first connecting rod 101, thus unfolding the second connecting rod 102. This allows the extension rod 105, support plate 4, and universal ball seat 5 to unfold and support the device. This allows the support points of the device to be adjusted at multiple angles during installation, improving the versatility and convenience of subsequent insulation monitoring.

[0089] Simultaneously, the extension rod 304 can be driven to extend from the support frame 301 by the first telescopic rod 302, thereby causing the various structures on the support bracket 306 to shift. Furthermore, the positioning top shaft 307 facilitates the rotation of the various structures on the support bracket 306 along the axis of the connection between the support bracket 306 and the snap-fit ​​plate 305, making it easier for the wiring assembly 3 to make multi-angle adjustments when wiring the lines.

[0090] Simultaneously, the second telescopic rod 309 is activated, and the drive shaft assembly 310 is displaced, causing the wire harness arc piece 312 to rotate along the axis point at the connection between the wire harness arc piece 312 and the support bracket piece 306. This causes the two wire harness arc pieces 312 on the support bracket piece 306 to move closer to each other, clamping the cable and ensuring the stability between the device and the cable, thus preventing the device from becoming loose during insulation monitoring.

[0091] Furthermore, with the pulley 203 and guide rod 204, the operator can push the monitor 205 and guide rod 204, and the pulley 203 moves along the guide rod 204 to move horizontally on the support crossbar 201 and support frame 1, thereby causing the cable bundle assembly 3 to move, so that the cable bundle assembly 3 can pull the cable, adjust the tightness of the cable bundle assembly 3 after the cable is bundled, and improve the convenience and versatility of the device during use.

[0092] As shown in the embodiments Figure 6 , 7As shown, the cross-sectional shape of the wire harness arc member 312 is set to arc shape, and the two wire harness arc members 312 are arranged opposite to each other. The wire harness arc member 312 is provided with a rubber sleeve for anti-slip.

[0093] It should be added that the arc-shaped cross-section of the cable bundling arc member 312 facilitates the two cable bundling arc members 312 to approach each other for cable bundling. At the same time, the rubber sleeve increases the friction between the cable bundling arc member 312 and the cable, ensuring the stability of the cable during bundling.

[0094] Unlike existing technologies, this application discloses an online power line insulation monitoring system. By enabling the extension rod 105, support plate 4, and universal ball seat 5 to unfold and support the device, the support points can be adjusted at multiple angles during installation. This improves the versatility and convenience of subsequent insulation monitoring. It also facilitates multi-angle adjustment of the cable bundling assembly 3 when bundling the line, clamping the cable to ensure stability between the device and the cable, preventing slackness during insulation monitoring, and adjusting the tightness of the cable bundling assembly 3 after cable bundling. This enhances the convenience and versatility of the device during use, allowing for appropriate fine-tuning according to the complex environment of the line laying. During insulation testing, it easily realizes the function of bundling and monitoring the line, offering both ease of use and good practicality.

[0095] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
