MSXB-F-270kVA 270kV AC Resonance Test System
This AC resonant test system is primarily designed for AC withstand voltage tests of 35kV and 110kV cables, 110kV main transformers, GIS systems, and circuit breakers.
It has a wide range of applications and is an ideal withstand voltage testing device for municipal, county-level high-voltage testing departments and power installation and maintenance engineering units.
The system mainly consists of a frequency converter, excitation transformer, reactor, capacitive voltage divider, and compensation capacitors.
1. 0.5km of 110kV/300mm² cable, capacitance ≤0.0735μF, test frequency 30-300Hz, test voltage 128kV, test time 60min
2. 2km of 35kV/300mm² cable, capacitance ≤0.389μF, test frequency 30-300Hz, test voltage 52kV, test time 60min
3. 5km of 10kV/300mm² cable, capacitance ≤1.88μF, test frequency 30-300Hz, test voltage 22kV, test time 60min
4. 110kV 5. For GIS, switchgear, and other substation equipment with voltage levels of 35kV and below, the test frequency is 30-300Hz, the test voltage is 265kV, and the test time is 1min.
6. For GIS, switchgear, and other substation equipment with voltage levels of 35kV and below, the test frequency is 30-300Hz, the test voltage is 95kV, and the test time is 1min.
1. It has overvoltage, overcurrent, zero-position start, and system detuning (flashover) protection functions.
2. The equipment weight and volume are 1/10-1/30 of ordinary testing equipment. The power required for testing is only 1 Q of the test capacity.
3. The device has three working modes: fully automatic mode, manual mode, and automatic tuning and manual voltage boosting mode.
4. Data storage and printing: The stored data is numbered for easy user identification and retrieval. 5. The starting frequency for automatic frequency sweeping can be set arbitrarily within a specified range.
6. DSP platform technology allows for adding or removing functions and upgrades according to user needs; the human-machine interface is more user-friendly.
7. Improves the waveform of the output voltage.
8. Prevents large short-circuit currents from burning out fault points.
9. No recovery overvoltage will occur.
