Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell component testing and relates to an insulation and wet leakage testing device. Background Art

[0002] The insulation and wet leakage tests of existing battery components are carried out on two instruments, one is an insulating tabletop for testing insulation resistance, and the other is a water tank for testing wet leakage.

[0003] When testing wet leakage, place the component in a groove and inject water. Because the component is in a groove shape, it is necessary to press down the component to prevent it from floating. After the test, turn off the power supply. Two people lift the component and pour the water in the groove of the component into the sink, and then put it on the ground to drain the water.

[0004] The existing process has the following problems: (1) The component area is large, which occupies a large laboratory area and increases operating costs; (2) The component is in a groove shape and is easy to float when placed in. Pressing the hand into the water increases ineffective movements and also increases the risk of electric shock; (3) When lifting out of the sink, the water in the component groove needs to be poured out, which consumes physical strength and reduces employee work enthusiasm; (4) Water remains on the edge of the sink, increasing the risk of electric shock during the operation; (5) When draining the water on the ground, water accumulates on the ground, increasing the risk of electric shock and affecting the cleanliness of the laboratory.

[0005] Therefore, inventing a device for insulation and wet leakage testing has high practical value. Utility Model Content

[0028] This embodiment provides an insulation and moisture leakage test device. Figure 1 The insulation and wet leakage test device comprises: an upper water tank 1, a diaphragm pump 2 and a lower water tank 3. The side wall of the upper water tank 1 is provided with a water injection port 4 and an overflow port 5. The overflow port 5 is connected to the lower water tank 3 through an overflow pipe. The lower water tank 3 is connected to the water inlet of the diaphragm pump 2 through an inlet pipe. The water outlet of the diaphragm pump 2 is connected to the water injection port 4 through an outlet pipe. A drain port 6 is provided at the bottom of the upper water tank 1. A first drain valve 7 is installed at the drain port 6. The first drain valve 7 is connected to the lower water tank 3 through a drain pipe. A support platform 8 for placing a solar cell module 9 is fixed in the upper water tank 1. The height of the overflow port 5 is greater than the height of the support platform 8.

[0029] The main function of the lower water tank is to store the water discharged from the upper water tank. When the water level in the upper water tank is too high, it flows into the lower water tank through the overflow port to prevent overflow from the upper water tank. When it is necessary to perform an insulation test or drain the water from the components, open the first drain valve to drain the water from the upper water tank into the lower water tank. When it is necessary to perform a wet leakage test, turn on the diaphragm pump to send the water from the lower water tank into the upper water tank. Therefore, the insulation and wet leakage test device of this embodiment can perform insulation and wet leakage tests. Compared with the use of two instruments for testing, it reduces the laboratory footprint and reduces operating costs; moreover, after the water from the upper water tank is drained into the lower water tank, the solar cell components are tested after the water is drained in the upper water tank. There is no need to lift the water tank, which avoids residual moisture on the ground, reduces the risk of electric shock, and reduces the difficulty and workload of operation.

[0030] The support platform 8 of this embodiment includes a high support platform 81 and a low support platform 82. A baffle for preventing the solar cell assembly 9 from sliding is provided on the side of the low support platform 82 away from the high support platform 81. The tops of the high support platform 81 and the low support platform 82 are both set as inclined planes with the same inclination angle. Because the solar cell assembly is in the shape of a groove as a whole, it is easy to float when placed in, and the assembly needs to be pressed down to prevent floating. In this embodiment, the solar cell assembly adopts the method of entering the water with an inclined surface, which prevents the solar cell assembly from floating, eliminates the action of pressing the hand into the water, and avoids the risk of electric shock.

[0031] Preferably, the support platform 8 of this embodiment includes a high support platform 81 and a low support platform 82. The low support platform 82 is set as a C-shaped structure, and the opening of the C-shaped structure faces the high support platform 81, which can constrain the movement of the solar cell assembly and prevent the solar cell assembly from sliding down the slope. The top of the high support platform 81 is set as an inclined surface. This embodiment adopts an upper water tank and a lower water tank, and the upper water tank is supported by a high support platform and a low support platform. The solar cell assembly adopts an inclined water outlet method to facilitate the discharge of water in the groove of the solar cell assembly, avoiding the heavy work of employees manually draining water.

[0032] The upper water tank 1 of this embodiment includes an inner tank made of polypropylene or random copolymer polypropylene and an outer tank 12 for supporting the inner tank 11. Polypropylene or random copolymer polypropylene has high impact resistance, strong mechanical properties, and resistance to corrosion by various organic solvents and acids and alkalis, so polypropylene or random copolymer polypropylene is used as the inner tank. The top of the inner tank 11 is set to be chamfered inwardly. Because the inner tank adopts a slope design, it can reduce the residual moisture at the edge of the inner tank and reduce the risk of electric shock.

[0033] The main function of the lower water tank is to store the water discharged from the upper water tank. The bottom of the lower water tank 3 of the present embodiment is provided with a second drain valve 10. When the lower water tank needs to be replaced with water or is not used for a long time, the water in the lower water tank can be conveniently drained.

[0034] The working principle of the insulation and wet leakage test device of this embodiment is as follows:

[0035] By designing an upper water tank and a lower water tank, the flow of water between the upper water tank and the lower water tank is completed through a diaphragm pump, a pipe and a drain valve, and the water in the upper water tank is drained to the lower water tank, thereby achieving the conditions for insulation testing in the upper water tank; by adding an inclined support platform in the upper water tank, it is ensured that the solar cell module enters the water at an inclined surface when entering the water, which is conducive to the water flowing into the groove of the module and avoiding the floating problem; at the same time, when the solar cell module is discharged from the water, it is also conducive to the discharge of water in the groove; the inclined support platform in the water tank provides conditions for draining the module.

[0036] The insulation and wet leakage test device of this embodiment solves the problems of large equipment footprint, much human intervention, high labor intensity, and high risk of electric shock.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All contents that do not deviate from the technical solution of the present invention should be included in the protection scope of the present invention.
