Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and particularly relates to a positioning sensor for cable pulse high-frequency current method. Background Technique

[0002] With the improvement of cable manufacturing technology, the probability of insulation failure of the cable body has been greatly reduced, and most of the failures occur in cable accessories. The main reason for cable accessory failures is that due to process problems during installation, there are insulation defects in the cable accessories. After the cable is put into operation, the electric field concentration at the defective part is very serious, resulting in too high local field strength, which is prone to partial discharge and ultimately leads to the breakdown of the cable joint, causing insulation accidents. When a local discharge occurs at the cable joint, a high-frequency pulse current will be generated instantaneously. This pulse current propagates along the cable body in the form of a guided wave to a distance and enters the ground through the grounding wire of the intermediate joint or terminal joint.

[0003] In order to quickly and accurately detect the cable pulse current, it is necessary to install a current sensor to detect the pulse current. The movable clamp is clamped on the cable body, and then the movable clamp is connected to the sensor. However, most sensors are installed by surface mounting and fixed on the wall or the ground, resulting in the sensor being easily affected by the surrounding environment during use.

[0005] To achieve the above purpose, the utility model provides a positioning sensor for cable pulse high-frequency current method, including a sensor. One side of the sensor is movably connected with a movable clamp. A plurality of movable grooves are fixedly installed on the end face of the sensor. Movable blocks are movably installed inside the movable grooves. An installation frame is fixedly installed at the upper end of the movable block. A plurality of springs are fixedly installed at the lower end of the movable block and are symmetrically arranged. A through groove is fixedly opened on the side of the movable groove. A stop block is movably installed inside the through groove.

[0006] Preferably, a connection block is fixedly installed at the upper end of the movable clamp. A fastening bolt is movably installed inside the connection block. A hinge is fixedly installed at the lower end of the movable clamp.
