System overall structure requirement
1. Three modules can be serial connection or parallel connection.
2. When three module serial connection, it must guarantee:
2.1 Transmission mechanism should be connected convenient and synchronism, the transmission should be flexible and low noise.
2.2 Each module’s location and fixation should be convenient, reliable, firstly, fix reactor, and then connect transmission shaft;
2.3 Its should be convenient for the current leading circuit between modules.
2.4 Each module voltage distribution almost corresponds with each other.
2.5 The connection of HV lead wire should be fixed and convenient;
3. Each reactor Z=f(δ) (The relations between impedance and air gap) characteristic curve should be almost same as each other, at the same air gap position, the different between impedance not surpass 5% of minimum value.
4. Reactors should have reliable air gap limit switch, and equip with air gap sensor, the user can read the iron coil’s gap on the control console.
5. Transmission device should has back-up protection treatment, in case of damage to the transmission from phase sequence opposite or air gap limit switch dysfunction
6. The system’s tuning and resonance function should be excellent. The system should not detuning when regulating device raise voltage, resonant(adjusting air gap) raise voltage or under any test voltage (not surpass rated voltage). And, when the exciter transformer output a relative low voltage (1-1.5kV), the system can also tuning to resonant state.
7. Regulating device should has the function regulation from zero position and auto return-to-zero function
8. The reactor’s air gap will back to the middle position after testing.
9. Regulator has the protection function when motor out of control.
10. Dimension requirement on transportation and crane
Structure:
Internal structure:
①. 30-Q-130 Grain-Oriented Electrical Steel,
②. There are earthing baffle between winding and iron coil, the earthing is reliable.
③. We do many improment on the system; abandon some unreasonable structure and creat our new resonant. New variable inductance power frequency resonant reactor’s working life not less than 60 years.
④. The iron steel has been done the chip removing treatment. And then form a entirety with curing agent, which lower the noise; equip guide rail between adjustable iron coil and fixed iron coil, to make sure the iron coil move vertical or horizontal. We have been leader of the power frequency variable resonant system, moreover, we cooperate with famous university and research institute and improve ours quality continuously.
