Overview

The ZJ-5SD motor turn to turn impulse withstand voltage tester can provide high testing impulse voltage and withstand large load capacity, making it particularly suitable for small and medium-sized AC/DC motor manufacturers to conduct turn to turn withstand voltage tests. This instrument is a new type of instrument that implements the GB755-87 and GB14711-93 standards, and is a means to improve the level and reliability of motor insulation testing in China. Complies with the standard JB/T 9615.1-2000 "Test Method for Interturn Insulation of AC Low Voltage Motor Loose Inlaid Winding".

Product Details

1、 Overview:

　　ZJ - 5SDThe inter turn impulse withstand voltage tester adopts the "pulse waveform comparison method" to conduct equivalent overvoltage simulation tests on the motor or coil winding with high voltage pulses to verify the impedance symmetry and balance of the coil winding. Pulse voltage waves with a certain wavefront time and specified peak values are alternately applied directly to the same designed test and reference line groups. The difference in attenuation oscillation waveforms caused by the impulse voltage between the two is used to distinguish whether the insulation between the motor winding turns is good, and the degree of difference reflects the severity of the coil turn fault. Good identification of inter turn short circuits, coil corona discharge, local short circuits, wiring errors, coil balance, etc. Due to the short wavefront time of the applied high-voltage pulse. Due to its low energy, it is considered a non-destructive test.

ZJ - 5SDThe inter turn impulse withstand voltage tester adopts a single circuit high-voltage line, peak voltage digital display, waveform oscilloscope display, integrated circuit of the whole machine, and easy and simple operation. Widely applicable for inter turn insulation testing of windings in micro special motors, small and medium-sized motors, high-voltage motors, transformers, relays, solenoid valves, etc.
