Description

Technical Field

[0001] The utility model belongs to the technical field of insulation testing, and in particular relates to a withstand voltage testing device for insulating boots. Background Art

[0002] The insulating boots (gloves) withstand voltage test device is based on the principle of electromagnetic induction, changing the input voltage to reach the maximum voltage required for the test. The insulating boots (gloves) withstand voltage test device generally includes a water tank, a test transformer and a control console. The control console can adjust the voltage and display the leakage current of the insulating boots or insulating gloves. The control console is usually equipped with overcurrent protection, zero protection, time protection and alarm functions.

[0003] The test principle is to connect 0~220V power supply, adjust the power frequency withstand voltage test bench, and according to the electromagnetic induction principle of the test transformer, make the transformer generate 0~30KV power frequency high voltage to each electrode, so that the insulating boots (gloves) can obtain the specified test voltage. According to the test procedures of insulating boots (gloves), read and record the test parameters.

[0004] During the test, you need to fill the water tank with water, place the insulating boots in the water tank, fill the insulating boots with water, extend the electrode rod into the water in the insulating boots, ground the water tank and the console, then turn on the power and adjust the voltage for testing.

[0005] The problem with the prior art is that when the insulating boots are tested for withstand voltage, water needs to be injected into the boots. After the test, the inside of the insulating boots is dry, which is inconvenient to operate and affects the delivery of the insulating boots. During the test, in order to ensure that the bottom of the insulating boots is in contact with the water body, a clip is usually used to clamp the boot opening and the test is suspended. The positioning stability of the insulating boots is insufficient and the operation is inconvenient. Summary of the invention

[0006] The utility model aims to provide an insulating boot withstand voltage test device for the problems existing in the prior art, which has the advantages of convenient operation, stable positioning and simple structure.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an insulating boot pressure test device, including a test bench, on which a water storage tank body, a mounting frame and a water inlet pipe for supplying water to the water storage tank body are arranged, on which a water inlet valve is arranged, the water storage tank body is connected to a drain pipe, on which a drain valve is arranged, a porous water-absorbing pad for placing insulating boots is arranged at the bottom of the water storage tank body, a conductive member is arranged between the bottom surface of the water storage tank body and the porous water-absorbing pad, the conductive member is connected to a connecting wire for grounding, a conductive wire for connecting a power supply is arranged on the mounting frame, an ammeter is arranged on the conductive wire, a conductive wire 2 is detachably arranged at the bottom end of the conductive wire 1, a conductive metal sheet is arranged at the bottom end of the conductive wire 2, and the shape of the conductive metal sheet corresponds to the shape of the inner bottom surface of the insulating boot.

[0008] In the above scheme, the components are connected through the test bench to facilitate the overall transfer, and a water inlet valve is set to control the water inlet pipe to supply water to the water storage tank body, so as to form a conductive area on the outside of the insulating boots. The switch of the drain pipe is controlled by the drain valve to facilitate the discharge of water in the water storage tank body after the test. The outer bottom surface of the insulating boots is supported by the porous water-absorbing pad at the bottom of the water storage tank body to ensure that the outer bottom surface of the insulating boots is fully in contact with the conductor and the test effect is ensured.

The conductive wire is used to connect to the high-voltage end of the power supply, and the conductive wire is used to maintain the circuit between the high-voltage end of the power supply and the conductive metal sheet. During the test, after the conductive metal sheet is installed on the inner bottom surface of the insulating boots, the voltage of the power supply is adjusted, and the leakage current generated under high voltage is tested by the ammeter, thereby testing the pressure resistance performance of the insulating boots. When the device is in use, there is no need to add water to the inside of the insulating boots, which simplifies the later drying work of the insulating boots and is easy to operate.

[0009] Furthermore, a metal hook is provided at the bottom end of the conductive wire 1, two ends of the conductive wire 2 are fixed on the conductive metal sheet, and the middle part of the conductive wire 2 is connected to the metal hook.

[0011] Furthermore, a plurality of conductive metal balls are filled between the top of the conductive metal sheet and the insulating boot.

[0012] When power is turned on, the conductive metal ball is used to increase the contact area between the conductive metal sheet and the insulating boot, so that the conductive metal sheet and the inner bottom surface of the insulating boot are tightly connected, thereby improving the test effect.

[0013] Furthermore, a return water tank is provided on the test bench, the outlet end of the drainage pipe 1 is connected to the return water tank, the return water tank is connected to a return water pipe, the return water pipe is connected to a circulation pump, and the return water pipe is connected to a water inlet pipe 1.

[0014] A return water tank is set up to recycle the water discharged from the drain pipe. The recycled water is transported to the water inlet pipe through the return water pipe and the circulation pump for use in the next test, thus recycling and saving resources.

[0015] Furthermore, the return water tank is provided with a second water inlet pipe and a second water discharge pipe, the second water inlet pipe is provided with a second water inlet valve, and the second water discharge pipe is provided with a second water discharge valve.

[0016] The second water inlet valve and the second drain valve are used to control the switches of the second water inlet pipe and the second drain pipe, so as to facilitate the discharge and replenishment of water in the return tank through the second water inlet pipe and the second drain pipe.
