IIISmall Wet Leakage Current Testing System (Conductivity Meter)Item Description

3.1 Insulated water tank

3.1.1 Adopting20Mm thick importedPPThe board is seamlessly welded and has characteristics such as insulation, earthquake resistance, impact resistance, high temperature resistance, and corrosion resistance. The sink is equipped with a cross shaped shelf inside, which facilitates the placement of test samples;

3.1.2 The sink is equipped with two solution outlets and a return outlet at both ends, and a drain outlet at the bottom. Two of the water outlets are connected to the water pump, and the pipe mouth is inclined at a 45 ° angle to prevent the solution from splashing around. The height of the return water outlet can be adjusted according to the test requirements, and the solution is sufficient to cover all component surfaces except for the incoming wire of the junction box (when the junction box is not designed to be waterproof);

Install a stainless steel filter screen at the inlet of the circulating water inlet;

3.1.4 Test sink separately configuredAdjustable sample rack，Using aluminum alloy and steel (with outer insulation strips)The angle is35°；

3.2Small Wet Leakage Current Testing System (Conductivity Meter)Circulating water source

3.2.1 It consists of a water tank, a heating and constant temperature device, a water pump, and pipelines;

3.2.2 The water tank is welded with imported SUS304 # stainless steel plate and connected to the insulated water tank by a water pump. Water tank inlet and outlet

Installation diameter of all water outlets1 "safety valve;

3.2.3The water tank replenishment device adopts an electronic level gauge to control the solenoid valve to automatically replenish water, and stops replenishing water when the water level reaches the set height;

3.2.4水箱外部equiptransparentThe water level gauge can directly observe the water level,For the convenience of peopleControl the liquid level high；

3.2.5 The water pump adopts an electromagnetic pump,Effluent flow rate60L/min， At 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;

3.2.6 The constant temperature heater adopts an immersion type all stainless steel electric heating rod, which has the characteristics of fast heating and good constant temperature effect. The output mode is SSR+solid-state
