AC voltage withstand test equipment system: suitable for handover and preventive testing of large capacity and high-voltage electrical equipment

The communication voltage withstand test equipment system uses new and innovative technology to complete various tests, reducing the required power capacity while overcoming the traditional resonance that can only meet the maximum working time of one cable for 3 hours. The patented technology design ensures the continuous voltage withstand requirements of multiple cables on the engineering site.

To meet different levels of voltage testing, multiple reactors are designed separately and can be combined according to on-site testing requirements.

The main functions and technical features of our company's communication pressure test equipment system are as follows:

1. The communication voltage withstand test equipment system has protection functions such as overvoltage, overcurrent, zero position start, and system detuning (flashover).

2. The weight and volume of the equipment are 1/10-1/30 of that of a regular testing device. The power required for the experiment is only 1/Q of the test capacity.

3. The device has three working modes: fully automatic mode, manual mode, and automatic tuning manual boost mode

4. Store and print data, with numerical numbers for easy identification and retrieval by users.

5. The starting point of the frequency during automatic frequency scanning of the device can be set arbitrarily within the specified range.

6. DSP platform technology can add or remove functions and upgrade according to user needs, making the human-machine exchange interface more user-friendly.

7. Improve the waveform of the output voltage.

8. Prevent large short-circuit currents from burning the fault point.

9. There will be no overvoltage recovery.
