[0041] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0042] like Figure 1-4 As shown, this embodiment provides a photovoltaic module insulation withstand voltage testing device, including:

[0043] Conveying unit 4 is used to transport photovoltaic modules and has a clearance space.

[0046] An insulation test unit is located above the lifting unit 6 and is used to contact the photovoltaic module after it is lifted by the lifting unit 6.

[0047] In practice, the photovoltaic module to be tested is placed on the conveying unit 4.

[0059] Specifically, after the photovoltaic module is lifted to a set height by the lifting unit 6, the second driving component drives multiple conductor components 2 to connect end to end in sequence to form a closed loop and make close contact with the outer periphery of the photovoltaic module. There is no need to manually install the ring conductor test component, and the degree of automation is high.

[0060] In this embodiment, the conductor component 2 is a conductive sponge. The conductive sponge is elastic and can better contact the photovoltaic module. There are four conductor components 2, which can be connected end to end to form a quadrilateral that matches the outer periphery of the photovoltaic module.
