Description

Technical Field

[0001] This utility model relates to the field of power distribution insulation monitoring technology, specifically to a power transmission and distribution insulation monitoring device. Background Technology

[0002] The power transmission and distribution insulation monitoring device is a key piece of equipment specifically designed for use in power systems. Its core function is to monitor the insulation status of AC cables in real time, so as to detect and warn of potential leakage problems in a timely manner. Through high-precision sensors and advanced signal processing technology, the device can continuously and accurately measure key parameters such as cable insulation resistance and leakage current, thereby effectively assessing the integrity and performance of the cable insulation layer.

[0003] Chinese Patent Publication No. CN209878935U discloses an online cable insulation monitoring device. This device mainly includes a mounting rod, a stop block, a first spring, a slider, a cleaning ring, and a drive device. Although the device is designed with a drive motor and a series of mechanical structures to achieve online monitoring of cable insulation and is equipped with a cleaning function to improve monitoring accuracy, it still has some limitations in practical applications. Specifically, this online cable insulation monitoring device is insufficient in adapting to cables of different diameters because the collar and rollers in the device are designed to be fixed and cannot be adjusted according to the actual thickness of the cable. Rapid cable replacement or adjustment can lead to the device failing to effectively clamp or adapt to the cable surface when faced with cables of different diameters, thus affecting the accuracy and stability of monitoring. When the cable diameter is small, the ferrule may not fit tightly against the cable, causing the roller to slide rather than roll on the cable surface. This not only affects the accuracy of monitoring data but may also damage the cable surface. Conversely, when the cable diameter is large, the ferrule may not completely wrap around the cable, preventing the roller from effectively clamping it, thereby affecting the stability of the device and the monitoring effect. Therefore, those skilled in the art provide a power transmission and distribution insulation monitoring device to solve the problems mentioned in the background art. Utility Model Content

Drive motor 3011 drives pulley 307 to rotate through bearing 305 and transmission rod 306.

[0028] As one implementation method in this embodiment, such as Figure 8As shown, the lifting mechanism 4 includes four springs 401 and four connecting bolts 402. The four springs 401 are slidably sleeved on the upper outer side of the four guide rods 301, and the four connecting bolts 402 are threadedly sleeved on the upper inner center of the four guide rods 301. The four connecting bolts 402 and the four guide rods 301 are detachably connected. The upper end of each of the four connecting bolts 402 is fixedly connected to a limit buckle 403.

The positioning bolts 404 and the positioning plate 405 are fixed together by the fastening knobs 406 to further enhance the stability of the lifting mechanism 4. When it is necessary to move the drive mechanism 3, the pulling force can be released or increased by adjusting the springs 401 and the docking bolts 402 in the lifting mechanism 4, thereby realizing the up and down lifting operation of the drive mechanism 3.

[0029] Working principle:

[0030] AC cable assembly 1 transmits current through conductive core 101. Insulating sleeve 102 ensures no leakage during current transmission. Leakage detection mechanism 2 consists of upper and lower clamping sleeves 201 and 202, which are slidably fitted on the outside of insulating sleeve 102. The cable is clamped by the contact of upper and lower mating plates 203 and 204, and by the fixing of fastening bolts 207 and fastening nuts 208. Teflon sheet 2010, as an insulating and wear-resistant material, fits tightly against the outside of insulating sleeve 102 to ensure the accuracy of leakage detection. Leakage detection ring 209 is used to detect whether there is leakage in the cable. Drive mechanism 3 achieves stable up and down movement by cooperating with guide holes 205 of leakage detection mechanism 2 through four guide rods 301. The mating sleeve 303 on support plate 302 is threadedly connected to guide rods 301 to ensure the stability of drive mechanism 3. Drive motor 3011 drives pulley 307 to rotate through bearing 305 and transmission rod 306. Anti-slip sleeve 308 increases the contact with insulation. The friction of sleeve 102 enables the drive mechanism 3 to move along the outside of the cable. The remote control module 309 allows remote operation of the drive motor 3011 and the audible and visual alarm 3010. When leakage is detected, the audible and visual alarm 3010 will sound an alarm. At the same time, the remote control module 309 can receive signals and take corresponding measures. The battery 3012 provides power support for the entire drive mechanism 3. The lifting mechanism 4 provides upward pulling force through four springs 401 to ensure that the drive mechanism 3 can maintain a certain position when not in operation. The docking bolt 402 and the limit buckle 403 cooperate with the guide rod 301 to realize the positioning and fixation of the lifting mechanism 4. The positioning bolt 404 and the positioning plate 405 are fixed together by the fastening knob 406 to further enhance the stability of the lifting mechanism 4. When it is necessary to move the drive mechanism 3, the pulling force can be released or increased by adjusting the springs 401 and the docking bolt 402 in the lifting mechanism 4, thereby realizing the up and down lifting operation of the drive mechanism 3.
