Technical Field
The invention relates to the technical field of withstand voltage tests of electric insulating rods, in particular to a device for simultaneously carrying out withstand voltage tests on a plurality of insulating rods.
Background
According to the regulations of the electric power safety work regulations, voltage withstand tests are required to be performed on insulating rod safety tools such as insulating rods and phase detectors every year so as to check the insulating performance of the insulating rod safety tools. This is because the insulation rod is used in field live working for a long time, and is inevitably aged, damaged or affected by moisture as the number of times of use increases, and the insulation performance thereof is also greatly reduced. If the insulating rod with poor insulating property is applied to field live-line operation, the insulating rod is extremely easy to cause harm to users. When the aged, damaged or damped insulating rod bears high-voltage electricity, phenomena such as insulating rod breakdown, flashover or overheating can occur, and therefore, a withstand voltage test is an effective method for verifying the insulating performance of the insulating rod.
In the withstand voltage test of the insulating rod, one end of the insulating rod to be tested is applied with voltage specified by regulations, and the other end of the insulating rod is grounded, so that the insulating rod is qualified to be free of breakdown, flashover and overheating in the withstand voltage test process. The traditional insulation rod voltage-withstand test can be only carried out by one, the insulation rod pressurizing end and the grounding end are required to be manually wound with bare copper wires each time, the winding is required to be reliable, the bare copper wires are ensured to be reliably contacted with the insulation rod, and otherwise, the test is unqualified; secondly, when the number of tests is large, the bare copper wires are frequently assembled and disassembled, time and labor are wasted, and hands of testers are often stabbed by burrs of the bare copper wires. In addition, the original test device is composed of two insulating stools, the distance between the two ends is not fixed, and the test distance corresponding to the voltage is measured by using a ruler before measurement is started every time, so that the test efficiency of the voltage resistance test cannot be improved.

The hole distance between the two paired circular holes penetrating through the stainless steel square pipe is 2cm, and the diameter of each circular hole is 3mm; the diameter of the steel wire ring is 2mm.
The whole testing device is fixed on the base, so that the withstand voltage testing distance can be fixed, and the testing distance corresponding to the voltage is not required to be measured by a ruler before measurement every time. The universal wheel is installed at the bottom of the device, so that the position can be adjusted conveniently during moving and testing. When the device is adopted for the insulating rod pressure test, the insulating rod can be inserted into the steel wire ring opening from the upper part of the stainless steel square pipe after the steel wire ring is pulled upwards through the thin rope, the two ends of the insulating rod to be tested are respectively placed in the steel wire ring openings above the stainless steel square pipes on the two sides, the thin rope is loosened, the steel wire ring is tensioned downwards under the action of the gravity of the conical weight and is tightly pressed on the insulating rod, the reliable contact between the steel wire and the insulating rod is realized by the cooperation of the conical weight, the stainless steel square pipe and the steel wire ring penetrating through the stainless steel square steel round hole, and further the pressure test of the insulating rod can be directly carried out. Because the plurality of groups of steel wire rings are arranged on the stainless steel square pipe side by side, the wiring of a withstand voltage test can be simultaneously carried out on the plurality of insulating rods, and the test is carried out, so that the working efficiency is greatly improved. The reverse locking device can lock the stainless steel round pipe which is rotated in place, so that the stainless steel round pipe is prevented from freely moving, and the safety and the reliability of the test are ensured. The invention realizes the reliable connection of the insulating rod and the steel wire through simple 'pulling, releasing and loosening', completes the steel wire winding of the insulating rod, replaces the operation of winding the bare copper wire on the insulating rod in the prior art, does not need to wind the bare copper wire manually any more, and avoids the hand from being stabbed.
