The main factors affecting the voltage resistance of electric heaters
Including the quality of insulation materials and the thickness of insulation layers, production process control, sealing materials and sealing processes.
Under normal circumstances, 100% testing is required for cold withstand voltage; Hot state pressure resistance should be tested as a sampling item when necessary. The withstand voltage test belongs to high voltage testing, and applying too high a voltage can cause hidden damage to the electric heater. Therefore, the higher the applied test voltage, the better. It needs to be carried out in accordance with standards (reference standards include IEC60335-1, UL1030, JB/T4088-2012, JB/T2379-2016).
leakage current
Leakage current refers to the current flowing through the insulating medium when a component reaches a stable operating temperature state.
Leakage current is one of the important indicators to measure the insulation quality of electric heaters, and it is the main indicator to measure the safety performance of products.
The measurement method for leakage current: Connect the component to the voltage, adjust the test voltage to make the input power equal to 1.15 times the rated power, and measure the leakage current after the component reaches stable operating temperature.
The main factors affecting leakage current
Including the quality of insulation materials, production process control, sealing materials and sealing processes, and working temperature.
Under normal circumstances, leakage current is measured as a sampling item according to standards (reference standards include IEC60335-1, UL1030, JB/T4088-2012, JB/T2379-2016) to verify the safety performance of the product.
Before leaving the factory, the leakage current of the electric heater shall not exceed 0.5mA, and specific industry standards shall also be followed for products.
Rated power deviation
Rated power deviation refers to the deviation between the actual input power and the rated input power of a component under normal operating conditions when the rated voltage is applied. The rated power deviation is one of the important indicators for measuring the performance stability of electric heaters.
