Pphotovoltaic junction box simulation waterproof and dustproof grade testing device

Abstract

The invention discloses a photovoltaic junction box simulation waterproof and dustproof grade testing device which comprises a base and a junction box, an air hole is formed in the top of the junction box, an elastic sealing ring is fixedly connected in the air hole, a sealing layer is fixedly connected to the bottom end of the elastic sealing ring, and a support is fixedly connected to the upper end of the base. The upper end of the support is fixedly connected with a fixed sliding barrel, a telescopic connecting barrel is slidably connected in the fixed sliding barrel, the top end of the telescopic connecting barrel is connected with a downward pressing mechanism through a connecting base, the downward pressing mechanism is connected with the support and the fixed sliding barrel, and the upper end of the telescopic connecting barrel is further connected with a vacuumizing assembly. A lead screw adjusting assembly is arranged on the surface of the base, the lead screw adjusting assembly is connected with two oppositely-arranged fixing plates, a fixing assembly is arranged on the front portion of one fixing plate, and a fixing groove matched with the fixing assembly is formed in the surface of one side wall of the junction box. The junction box is provided with the air hole, and the junction box can be vacuumized through the vacuumizing assembly, so that nondestructive testing of the junction box is realized.

Description

technical field

[0001] The invention relates to the technical field of photovoltaic junction boxes, in particular to a photovoltaic junction box simulation waterproof and dustproof level test device. Background technique

[0002] Solar energy is an inexhaustible green energy, which is very important for human beings to solve energy shortage problems and environmental pollution problems. With the development of science and technology, photovoltaic power generation technology has also made great progress. Power plants have been established one after another, which puts forward higher technical requirements for related components such as photovoltaic junction boxes, connectors, cables, etc. Solar photoelectric conversion devices are generally installed in remote fields and high altitudes, and it is troublesome to replace parts for maintenance. Therefore, choosing high-quality photovoltaic junction boxes and other components is an effective means to avoid high repair and mainte...
