Description

Technical Field

[0001] The utility model relates to the technical field of insulation withstand voltage testing, in particular to a withstand voltage insulation testing tool. Background Art

[0002] A technical means to test and evaluate the insulation withstand voltage capability of electrical equipment. All electrical equipment needs to use insulation structures to isolate the live parts from the grounded parts, or from other live parts with non-equipotential potentials, to ensure the normal operation of the equipment.

[0003] The dielectric strength of a single insulating material is expressed as the average breakdown electric field strength along the thickness (in kV / cm). The insulation structure of electrical equipment, such as the insulation of generators and transformers, is composed of a variety of materials and has a very complex structure. Any local damage to the insulation structure will cause the entire equipment to lose its insulation performance. Therefore, the overall insulation capacity of the equipment is generally expressed by how high the test voltage can be tolerated (in kV).

[0004] The insulation withstand voltage test voltage can indicate the voltage level that the equipment can withstand, but it is not equivalent to the actual insulation strength of the equipment. The specific requirement of power system insulation coordination is to coordinate and formulate the insulation withstand voltage test voltage of various electrical equipment to indicate the insulation level requirements of the equipment.

[0005] At present, the insulation withstand voltage test is the most commonly used technical means to inspect and evaluate the insulation withstand voltage capability of electrical equipment.

[0006] However, existing insulation and withstand voltage equipment only focuses on the test itself, the test supporting tooling does not support expansion, the program is fixed, and the test channel of the test product cannot be effectively switched, and the adaptability rate to insulation and withstand voltage instruments is low.

[0010] The test terminal D is electrically connected to the rotary switch B; the rotary switch B is electrically connected to the high voltage pin C;

[0011] The housing A is an insulator with high dielectric strength.

[0012] Furthermore, the knob switch B is a three-stage high-voltage explosion-proof mechanical knob switch with self-locking.

[0013] Furthermore, the number of the knob switches B is 6, and the 6 knob switches B are arranged in two rows and three columns.

[0014] Furthermore, the number of the test terminals D is 6, and the 6 test terminals D are arranged in a row.

[0015] The test terminal D cooperates with the knob switch B to achieve free expansion.

[0016] Furthermore, the shell A is made of flame-retardant ABS material.

[0017] Flame retardant ABS is an ABS engineering plastic that has flame retardant added to it.

[0018] Furthermore, the high voltage pin C is a cylindrical plug-in, which has stable contact.

[0019] Furthermore, the high voltage pin C includes: a positive pin and a negative pin.
