The LK-HT high-voltage harness comprehensive tester is mainly used for testing high-voltage harnesses of new energy vehicles, special industrial harnesses, aerospace high-voltage harnesses, etc. New energy vehicles generally use voltage platforms up to 300V~1000V, or even higher.High voltage cables are used to connect high-voltage batteries, inverters, air conditioning compressors, three-phase generators, and electric motors, thereby achieving the transmission of power electricity.Require the testing equipment to provide test signal outputs of up to DC6000V/AC5000V or higher. The LK-HT series can automatically complete the conductivity, insulation, voltage resistance, and airtightness tests of high-voltage cables. Its unique high-voltage pulse detection technology can quickly cut off discharge phenomena within 25us, ensuring the safety of test objects and personnel.

Function Overview:

lThe product can meet the requirementsGB/T18384 Safety Requirements for Electric Vehicles and Testing Requirements for GB/T20234 Electric Vehicle Charging Devices and Other Standards

lIt can accurately measure the conduction resistance and contact resistance of high-voltage wiring harnesses, with testing accuracy up to10u Ω.

lInsulation withstand voltage testing function: automatically completes multi-point insulation withstand voltage testing. The boost time and test time can be adjusted to quickly test the insulation resistance and leakage current between lines and between lines and shields.

lVoltage withstand testing can distinguish between real and imaginary leakage currents. Real leakage current can truly reflect cable material issues, while imaginary leakage current reflects cable parasitic capacitance.

lHigh voltage discharge monitoring function: During the withstand voltage test, monitor the tested wire harness to ensure thatShort cycle discharge phenomenon of 25us and cutting off high-voltage output to protect the safety of testing personnel
