Embodiment Construction

[0022] The core of the present invention is to provide a spray test device so as to better complete the spray test of the battery board.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] In the UL1703 standard, the regulation on spraying water is "33.6 The resistivity of the water used in the test before the test is 3500±175Ω·cm (25°C), and the resistivity after the test is not less than 3200Ω·cm and not greater than 3800Ω· cm (25°C)", the compliance requirements or compliance standards mentioned in the embodiments of the present invention are the standards, and can also be regarded as compliance with rainwater standards.

[0025] Please refer to figure 1 , figure 1 It is a schematic structural diagram of the spray test device provided by the embodiment of the present in...

Abstract

The invention discloses a spraying testing device which comprises a groove-shaped working table, a water storage tank and a spraying system, wherein the water storage tank is communicated with the groove-shaped working table; the spraying system is used for spraying water and is communicated with the water storage tank; a temperature control device is arranged inside the water storage tank; the spraying system is provided with a power pump; the temperature of the spraying water is 25 DEG C; the resistance of the spraying water is 3500+ / -175omega cm; when the spraying testing device is used, the temperature of the spraying water is 25 DEG C and the resistance of the spraying water is 3500+ / -175omega.cm, so that the requirements in UL (Underwriters Laboratories) standards are completely met, the actual situation of rainwater is simulated well; and meanwhile the spraying water flows into the water storage tank after being sprayed to a battery panel put in the groove-shaped working table, and is sucked into the spraying system by the power pump, thereby a circulation system is formed; the spraying water which meets the standards can be used in circulation, so that the production cost is reduced; and meanwhile the temperature control can be carried out; and by adoption of the spraying testing device provided by the invention, the spraying test to the battery panel can be accomplished well.

Description

technical field [0001] The invention relates to the field of spray test technology, in particular to a spray test device. Background technique [0002] The spray test device is mainly used to test the insulation performance of the battery panel itself and whether it affects its power generation capacity when it is sprayed or soaked in outdoor rainwater. Since there is no professional spray test device for battery panels in China, the insulation and electrical properties of the battery panels in outdoor rainy weather cannot be detected, which brings great hidden dangers to product quality and safety, and reduces customers' expectations for products. Credibility. [0003] At present, there is no professional spray test device for solar panels in the domestic solar industry, especially the spray test device for UL certification. The UL certification test must be sent to the United States, and the round-trip process is long. Due to transportation problems, the test results are ...
