The invention relates to a simulative waterproof and dustproof level tester for a photovoltaic junction box, which belongs to the technical field of a photovoltaic assembly tester. The simulative waterproof and dustproof level tester for the photovoltaic junction box comprises a vacuum source, a main test desk, and more than one or two test systems. Each test system comprises a hand-pull vacuum valve, a fixed tool, a pressure valve and a pressure meter. The hand-pull vacuum valve comprises a valve body, a valve cover, a piston, an air inlet tube and an air outlet tube. A cylindrical bump of the valve cover is screwed in a cylindrical chamber of the valve body. The hand-pull vacuum valve, the pressure valve and the pressure meter are arranged on a work panel of the main test desk. The air inlet tube is connected with an extraction hole of the fixed tool by a hose and the air outlet tube is connected with the vacuum source by a hose. The pressure valve is connected with both ends of a cylinder of the fixed tool by a hose. The pressure meter is connected between the hand-pull vacuum valve and the photovoltaic junction box by a hose. The simulative waterproof and dustproof level tester for the photovoltaic junction box has the advantages that the simulative waterproof and dustproof level tester for the photovoltaic junction box is convenient to operate and has fast test speed; that each person can test 180 pieces of photovoltaic junction boxes every hour, 100% flawless detection of the photovoltaic junction boxes can be ensured; and the tested product reaches the level of IP67.
Description
