I.Overview
Transformer DC resistance is a must-test item for semi-finished products in finished transformer manufacturing, finished product testing, installation, overhaul, change of tap-changer, handover test and preventive test in the power sector. It is possible to check the welding quality of the winding joint and the presence or absence of the turn-to-turn short circuit of the winding, and it is possible to detect whether the contact of each position of the voltage tap changer is good and whether the actual position of the tap changer and the indicated position are consistent, whether the lead wire is broken, and the multi-strand wire is wound. Whether there are broken shares and so on. In order to meet the needs of rapid measurement of DC resistance of transformers, our company developed HZ-3100A DC resistance tester. The whole machine is controlled by high-speed single-chip microcomputer with high degree of automation and automatic discharge and discharge alarm function. The instrument has high test accuracy and easy operation, and can realize rapid measurement of the direct resistance of the transformer.
II. Security measures
1. Be sure to read this manual carefully before using this instrument.
2. The operator of the instrument should have common knowledge of the use of general electrical equipment or instruments.
3. This instrument can be used indoors and outdoors, but should be used away from rain, corrosive gas and other places.
4. The instrument should avoid severe vibration.
5. Maintenance, care and adjustment of the instrument should be carried out by professionals.
6. After the test is completed, be sure to wait for the discharge alarm sound to stop before turning off the power and remove the test line.
7. To measure the no-load voltage regulating transformer, be sure to switch the gear position after the discharge indicating alarm sound stops.
8. During the test, it is forbidden to move the test clip and power supply line.
