XTSFQ-5KVA/360V Triple Frequency Induction Withstand Voltage Test Device

Estimated delivery : 45 Days; MOQ : 1 PCS
Product Introduction Overview :
This product is designed according to the Chinese standard "GB311-61" and the "Electrical Equipment Preventive Test Procedure" issued by the former Ministry of Water Resources and Electric Power to meet the power system's requirements for high-voltage transformer frequency double-frequency induction withstand voltage test equipment. It is widely used in the AC withstand voltage test of 35-220kV series-excited voltage transformers in the power system to assess the main and slave insulation strength of the transformer. It can also be used for induction tests on the windings of motors and small transformers; it can also be used as a short-term 150Hz power supply.
Features :
A three-core five-column structure is adopted, and 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 wave potential (positive sequence vector) in the secondary winding with the openings connected in a triangle is 0, and the two ends of the openings should produce the same-phase 150Hz third harmonic (zero sequence).
