Huazheng Electric HZ-3120A 20A Portable Transformer DC Resistance Tester

Summary

Transformer DC resistance is the required test item of semi-finished products, finished product factory test, installation, overhaul, change of tap switch, handover test and power department preventive test of the transformer in transformer manufacturing. It can check the welding quality of the winding joint and whether the winding is an inter-turn short circuit, detect whether each position of the voltage tap switch is good, whether the actual position of the tap switch is consistent with the indicated position, whether the lead line is broken, and whether multiple strands are broken. In order to meet the needs of rapid measurement of transformer DC resistance, the HZ-3120A DC resistance tester developed by our company. The instrument adopts the new power supply technology, which has the characteristics of small volume, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high-speed Scontroller with high degree of automation and automatic discharge and discharge alarm function. The instrument test has high accuracy and simple operation, and can realize the rapid measurement of transformer direct resistance.
