Description

Technical Field

[0001] This utility model relates to the field of high-voltage insulation testing technology, specifically a high-voltage insulation testing device. Background Technology

[0002] Insulating rods are critical safety tools in power systems, typically made of epoxy resin or fiberglass, used in scenarios such as live-line work and equipment maintenance (e.g., operating high-voltage disconnect switches). Their core function is to block current from passing through personnel, preventing electric shock accidents. Insulating rods require periodic sectional withstand voltage tests to verify that their insulation strength meets standards.

[0003] As described in patent CN221667856U, existing insulating rod testing devices achieve length adjustment and segmented testing through structures such as adjustment frames, combination frames, and support frames, but still have the following shortcomings in use:

[0004] The bearing groove is only an open groove. When multiple insulating rods are placed side by side, the ends are prone to misalignment, which leads to distortion of the test electric field and a surge in the risk of partial discharge. Utility Model Content

[0016] Furthermore, the conductive component includes two support rods that are vertically fixed at both ends of the top surface of the support base. A fixed conductive strip is fixedly installed between the top ends of the two support rods. A voltage-conducting strip is hinged to one end of the fixed conductive strip, and a locking hole is provided at the other end of the fixed conductive strip.

The support seats are slidably connected to the two guide rods 4 through the thread. A set of conductive components 9 are fixedly installed on the top surface of the two support seats.

[0041] A motor 7 is fixedly mounted on the outer side of a mounting plate 2. The end of the bidirectional lead screw 5 near the motor 7 rotates through the mounting plate 2 at the corresponding position and is fixedly connected to the output shaft end of the motor 7.

[0042] A scale 17 is set on the outer periphery of a guide rod 4.

[0043] Among them, a support block 6 is fixedly installed at the middle position of the top surface of the base 1, which is perpendicular to the bidirectional lead screw 5;

[0054] When installing the insulating rods, place multiple insulating rods parallel between the conductive foam protrusions 19 that fix the conductive strip 18; then rotate the screw 14 by the knob 15 to move the slide block 11 along the slide rod 10 to the end of the insulating rod, driving the alignment pressure plate 12 to press against the end face of all the insulating rods.

[0055] During testing, flip the conductive strip 20 to cover the insulating rod, so that the conductive foam protrusion 19 clamps the insulating rod from top to bottom; use bolts 23 to pass through the connecting plate 22 and lock it to the locking hole of the fixed conductive strip 18; connect the electrode post 21 of one set of conductive components 9 to the high-voltage transformer, and the other set of ground wires to start the segmented withstand voltage test.

[0056] In this invention, by setting up an alignment component, the ends of multiple insulating rods can be forced to be aligned, eliminating electric field distortion caused by length deviation and improving test accuracy.

[0057] In the length adjustment mechanism, the bidirectional lead screw 5 drives two sets of conductive components 9 to move synchronously and symmetrically. Combined with multiple sets of conductive foam protrusions 19 on the fixed conductive strip 18, it supports the simultaneous installation, alignment, and testing of multiple insulating rods, improving testing efficiency. The conductive foam protrusions 19 can adapt to the surface curvature of the insulating rod, ensuring uniform conductivity throughout the entire length.
