Description

Technical Field

[0001] The invention relates to the technical field of power transmission line maintenance, in particular to a high-voltage insulation electrical testing device which is easy to adjust. Background Art

[0002] A high-voltage insulation test device is a device used to determine whether a device is energized. It is usually composed of a detection probe and an insulating rod. The detection probes are classified into low voltage, high voltage and ultra-high voltage according to the voltage level. The detection probes are not universal for all lines. It is necessary to select a matching detection probe based on the voltage level, type (AC / DC) and specific usage scenario of the line. The reason is that voltage level mismatch can lead to serious safety hazards and insufficient insulation strength. Lines of different voltage levels (such as 10kV, 35kV, 110kV, etc.) have different requirements for the insulation performance of the tester; the detection sensitivity is incompatible. The electric field strength of the high-voltage line is much higher than that of the low-voltage line. If a low-voltage detection probe is used to detect the high-voltage line, false alarms or component damage may occur due to excessively strong electric fields. Conversely, the high-voltage probe may not be able to sensitively detect the weak electric field of the low-voltage line, resulting in missed detection.

[0003] The Chinese patent with the announcement number CN214278290U proposes a non-contact ultra-high voltage direct current transmission line electric detection device, including an electric field sensor, a movable unit, an electrode probe and a support rod. The electrode probe is installed at one end of the electric field sensor. The bottom of the electric field sensor is fixedly connected to an insulating sleeve. The inner wall of the insulating sleeve is provided with a thread. The inner thread of the insulating sleeve is connected to a threaded rod. The upper end of the support rod is provided with a receiving groove. The wall of the receiving groove is symmetrically provided with a slide. A slider is slidably connected in the slide groove. The two sliders face each other. The end passes through the corresponding slide groove opening and extends into the receiving groove, and is fixedly connected to the outer wall of the insulating sleeve. The bottom end of the threaded rod is rotatably connected to the bottom of the receiving groove through a first bearing. A first worm gear is fixedly sleeved on the rod wall of the threaded rod. The first worm is rotatably connected to the wall of the receiving groove through two second bearings. The first worm and the first worm gear are meshed with each other. One end of the first worm is fixedly connected to a turntable. An insulating tube is fixedly sleeved on the movable unit. A second worm gear is fixedly sleeved on the wall of the insulating tube. A mounting plate is fixedly connected to the electric field sensor.
