Photovoltaic module wet leakage current testing system

1、 Purpose:
Photovoltaic module wet leakage current testing systemTest the insulation performance of the component under humid working conditions, detecting whether moisture from rain, fog, dew, or snow has entered the working part of the internal circuit of the component,Causing corrosion, electrical leakage, and non safety accidents to it. The photovoltaic module wet leakage current testing system is a specially designed wet leakage current testing device for the solar photovoltaic module industry.
2、 Camay Photovoltaic Module Wet Leakage Current Testing SystemKM-PV-WLSystem equipment composition
Experimental sink, sink usage1.5cmThick importsPVCMade of board, with a circulating water tank at the bottom of the sink,PVCPipe, with diameters on both sides of the pipe body5mmSmall hole, stainless steel filter screen installed at the circulating water inlet, one drainage outlet, water switch diameter1″
Temperature controlled sink, temperature controlled22±3℃, using1/4hpPump, outflow flow rate100L/minAt the outlet, a ball valve is used to control the inlet pipe along the edge of the water tank, with multiple holes for diversion, allowing the inlet water to flow evenly.
Heating system, immersion type（SUS304）Stainless steelUType double tube heater, single tube can also be independently adjusted, heating is fast, temperature control is accurate, and the water level in the box is automatically replenished;
Spray device, a spray device containing the same solution. Contains three sprinkler heads, each equipped with a water pressure gauge and a water flow control valve; Control the pressure of each sprinkler head within34.5KpaThe distance from the nozzle to the component is approximately0.9MSpray angle and component composition45 degrees, in accordance withUL1703regulations.
The control cabinet adopts the concept of integrated instrument and equipment control, and the control system is installed in the front of the sink bracket for easy setting and observation by operators.
