General Information:

Substation Electrical Apparatus AC Resonance Test Systems, mainly composed of the frequency control power, incentives transformers, reactors, capacitor divider formed , designed for testing AC voltage 220kV and below , transformer, GIS systems, SF6 switches, cables, casing and other capacitive devices .

This Series can meet the high-voltage, low current device test conditions require, but also to meet the low-voltage, high current device test conditions require, with a wide scope of application , is idea test equipment for power department, repair engineering units.

Features:

The same voltage level, the capacity of the reactor with its smaller, lighter; small temperature rise at rated load; epoxy cast dry-type, high mechanical strength, electrical insulation is good, beautiful and reliable;

Frequency control large source capacity margin; protection strong; output waveform is good; stability; with a variety of operating modes, easy to operate; use 220V or 380V single-phase power, easy on-site to take power;

3. Flexible configuration. Optional different types of reactors to meet the different test requirements to achieve a multifunctional, cost-effective;

The power inverter SPWM imported dedicated chip digital waveform, the frequency resolution of 16, when the frequency in the 20 ~ 300Hz fine of up to 0.1Hz, while using a non-synchronous fixed-carrier orthogonal modulation, to ensure the entire frequency range output waveform good;

Power part of the use of advanced IPM module, to ensure stability and security apparatus;
