Electronic Multi-frequency Generator

Description

Electronic multi-frequency test device, multi-frequency withstand voltage test device, multi-frequency generator, electronic multi-frequency generator, electronic triple-frequency generator, transformer induction withstand voltage device

Detailed Product Description

The inductive withstand voltage test of transformers and mutual inductors is an important test to ensure that the product quality meets the national standards. The longitudinal insulation induction withstand voltage test between turns, between layers, between segments and between phases of transformer windings is an important item in transformer insulation test. The longitudinal insulation test needs to pass the frequency double power supply device, apply the test voltage, and carry out the withstand voltage test.

Meet the inductive withstand voltage test of 35kV and below voltage transformers

1. Help customers realize preventive AC withstand voltage test and handover AC withstand voltage test of various tested products;

2. Test the insulation of cross-linked rubber-plastic power cables, power transformers, GIS, transformers, insulators, generators, switches, etc. to withstand various over voltages.

AC withstand voltage test of force and capacitive load.

Product Feature

Device capacity: 5kW

Input voltage: AC, three-phase, 380V±10%.

Power frequency: 50Hz.

Output voltage: 0 ~ 400V

Output frequency: 50Hz, 100Hz, 150Hz, 200Hz (optional).

Waveform distortion rate: <3%.

General Technical Data

1. Parameter presets, protection settings, frequency selection, voltage adjustment control, etc., all adopt digital control technology. Built-in computer, 8-inch color LCD display, data storage can reach 3200 groups.
2. Using touch operation mode, equipped with thermal printer for Chinese character printing.
3. The test frequency of 50Hz, 100Hz, 150Hz, 200Hz can be preset (optional), and the voltage can be adjusted by touch mode (the step length can be adjusted in real time, select 1V, 2V, 5V, 10V), which can realize the multi-frequency test of the device Voltage output.
4. The external LC filter loop ensures that the waveform distortion rate is within the range of the index. An external tapped compensation inductor is used to compensate the capacitive current of the device under test and improve the load capacity of the device.
5. Because the generation principle of the traditional three-phase five-column triple frequency generator is abandoned, the following advantages are brought:
6. Small size, light weight, easy to carry and high power.
7. Not only generates three times the frequency, but also produces 1, 2, 3, and 4 times the test voltage output.
8. The operation and wiring are simple, and the requirements for the power supply capacity of the field test are greatly reduced.
