Product Description

Product introduction
Transformer direct resistance tester is a must-test item for semi-finished products, finished products factory test, installation, overhaul, change of tap changer, handover test and preventive test of power sector in transformer manufacturing. It can check the welding quality of the winding joint and whether the winding is short-circuited between turns. It can check whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the lead wire is broken, and the multi-strand wires are wound in parallel. Whether there is a stock break, etc. In order to meet the needs of fast measurement of transformer DC resistance, the transformer DC resistance tester developed by our company. The transformer DC resistance tester adopts a new power supply technology, which has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and perfect protection function. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, and has the functions of automatic discharge and discharge alarm. The instrument has high test accuracy and simple operation, and can realize fast measurement of transformer direct resistance.

Product Features
1. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation and easy operation.
2. Adopt high-frequency switching power supply technology, large output current, suitable for DC resistance measurement of large and medium-sized transformers
3. The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable
4. With audible discharge alarm, clear discharge indication, reduce misoperation
5. The response speed is fast, the on-load tap-changer can be directly converted in the measurement state, and the instrument automatically refreshes the data
6. The vertical chassis structure is adopted, which is convenient for on-site use
7. Intelligent power management technology, the instrument always works in the minimum power state, effectively reducing the internal heat of the instrument and saving energy. Can work for hours without interruption
8. Dot-matrix LCD, Chinese menu, printout
