Overview
Widely used for AC withstand voltage testing of 35-110kV series voltage transformers in power systems, to assess the main and auxiliary insulation strength of the transformers, and also for induction testing of the windings of motors and small transformers; It can also be used as a 150Hz power supply for short-term operation.
Product Details
Overview
This product is designed according to the Chinese standard GB311-61 and the "Preventive Testing Regulations for Electrical Equipment" issued by the former Ministry of Water and Electricity in January 1985, to meet the requirements of the power system for high-voltage transformer frequency doubling induction withstand voltage testing equipment. It is widely used for AC withstand voltage testing of 35-110kV series voltage transformers in the power system to assess the main and auxiliary insulation strength of the transformers, and can also conduct induction tests on the windings of motors and small transformers; It can also be used as a 150Hz power supply for short-term operation.
structure
Adopting a three core five column structure, the working magnetic flux density of the iron core is selected to be above the saturation magnetic flux density, so that the vector sum of the fundamental potential (positive sequence vector) in the secondary winding connected in a triangular shape is 0, and the 150Hz third harmonic (zero sequence) of the same phase should be generated at both ends of the opening.
