Recently, kvtester received an order for ZC-205c three-phase DC resistance tester. Our R & D department broke down the order according to the customer's requirements and functional requirements, designed and customized on demand, and carried out the R & D and improvement of ZC-205c three-phase DC resistance tester. After continuous improvement and testing by technicians, we finally met the customer's needs, completed the R & D and arranged production on demand.
The DC resistance of the transformer is a necessary test item for the factory test, installation, handover test of semi-finished products and finished products in the manufacturing of the transformer and the preventive test of the power department. It can effectively find the manufacturing defects such as material selection, welding, loose connection parts, lack of strands, broken wires and other hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, our company has developed a three channel DC resistance tester for yn connecting winding. The instrument realizes the functions of three-phase power on at the same time, independent current sampling and voltage sampling, measuring and displaying three-phase resistance value and three-phase unbalance rate at the same time, greatly shortens the test time of transformer DC resistance, and solves the problem of long time-consuming DC resistance test of each tap winding of power transformer. The time required is only 1 / 3 of that of traditional methods.
Zc-205c three-phase DC resistance tester is a new generation product of transformer DC resistance measurement. It is optimized for measuring the DC resistance of three-phase winding of large capacity transformer. The three-phase winding DC resistance of the transformer can be tested at the same time. For the on load voltage regulating transformer, the tap changer can be directly adjusted without discharge. The measurement time is one third of that of the traditional single-phase measurement, which can greatly shorten the working time and labor intensity. The instrument adopts large screen LCD and full Chinese graphical interface, which is clear and intuitive and easy to operate. It is equipped with panel printer and large capacity nonvolatile memory, which can store 255 test data. The test data is stable, fast and repeatable. It is the best choice for on-site measurement of transformer DC resistance.
At present, zc-205c three-phase DC resistance tester has been freshly baked, the test and calibration have been completed, the goods have been inspected, the equipment has been packed and ready to be delivered to Malaysia transformer factory. In this cooperation, kvtester stands out among many manufacturers with the same production qualification by virtue of professional technology and service and superior testing function of products.
