Introduction
Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products, factory test, installation, overhaul, after changing the tap changer, handover test and preventive test in the power sector. You can check the welding quality of the winding joints and whether the windings have short-circuits between turns. You can check whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, and whether the lead wire is broken. Whether there is stock breakage, etc. In order to meet the needs of rapid measurement of transformer DC resistance, the XHZ1005 transformer winding DC resistance tester adopts a brand-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 functions. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, with automatic discharge and discharge alarm functions. The instrument has high test accuracy and easy operation, which can realize rapid measurement of transformer direct resistance.
Main features
1. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation and easy operation.
2. The instrument adopts brand-new power supply technology, has many current gears, and has a wide measuring range, which can be automatically selected according to the load. Select current, suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
3. The protection function is perfect, which can reliably protect the impact of the back EMF to the instrument, and the performance is more reliable.
4. With audible discharge alarm, clear discharge instructions, reducing misoperation.
5. Fast response speed.
6. Intelligent power management technology, the instrument always works in the minimum power state, which effectively saves energy and reduces heat generation.
7.480X272 dot matrix ultra-small pixels 65K true color LCD,
