High Voltage Energy Saving System
System Composition - High Voltage Energy Saving System1. chief control unit
1). Parameter settings, the system running and monitoring are conducted by the CPU.
2). True Color LCD touch screen; brief and intuitive display of system monitoring situation;
3). Built-in PLC-specific technical requirements for transmission control; can set programmes
2. power unit
1).several serial power unit modules compose the control circuit of each phase
2)modular power units are installed in the power control cabinet which is convenient to disassemble and maintain
3).Strong fault-tolerant function of the power unit control loop ensures the reliability of the system. If a certain power module breaks down, it can bypass the power unit out and reduce the electrical load, so that the system can keep running with the remaining power units;
3. Phase-shifting transformer
specially designed input isolate transformer is of compact structure and perfect cooling wind channel which enable it to enjoy long life span under normal conditions.
Basic Principle - High Voltage Energy Saving System
1. ESE-GY Series High Voltage Energy Saving System is composed of phase-shifting, current-adjusting and multiple inverted output circuits. The chart below shows the low-voltage power unit becomes high-voltage output structure by multiple superimpositions. Each power module is of the secondary winding power supply of the input isolation transformer, which is of 590 input voltages and six for each phase. Therefore, the phase voltage is 3540V and the corresponding wire voltage is 6KV. There is a phase drop between the secondary winding groups which supply power to power unit. It realizes multiple inputs to remove the harmonics generated by the power units.
2. Each power unit module is of I GBT three-phase input. The output situation of single phase output inverter (pulse width adjustment type) is: 1,0,-1. By superimposing the six units of each phase can produce thirteen different voltages. Ell has perfect superimposed voltage output waveform.
System Features of High Voltage Energy Saving System
1. pure power input without harmonics interference
ESE-GY series high voltage energy saving system can meet the strict requirements of the harmonic distortion proposed by the power supply department and can avoid other networked electrical devices suffering harmonic interference. Do not have to worry about the expensive harmonic filters and related resonant problems.
2. high power factor
the power factor under normal speed range is higher than 0.96. do not need any power capacitor.
3. high quality power output
1) As a result of a multiple of the PWM design, ESE-GY series of high-voltage energy-saving system can provide the perfect sine without any input filter.
2) Multiple PWM output waveform can avoid electrical equipment heating caused by harmonic currents.
3) No matter how long the output cable of high-voltage energy-saving equipment is, it can protect electrical devices from the damage of common mode voltage and dv / dt stress;
4) Even the motor is running at low-speed, there was no shortage of torque problems caused by the harmonics of high-voltage energy-saving system. It can meet insulation requirements for normal electrical devices and cables.
Reliability of the system - High Voltage Energy Saving System 1) Application of mature and reliable technology, combined with multi-control technology, relatively independent power unit integrated ESE-GY series of high-voltage energy-saving system can ensure maximum reliability.
2) Surge protection circuit; protect energy-saving high-voltage system against instantaneous over-voltage.
3) ESE-GY series of high-voltage energy-saving system, which can withstand 100 ms without power grid electricity while energy saving high-voltage system can operate normally.
4) ESE-GY series of high-voltage energy-saving system can withstand ± 20% of the power grid voltage fluctuations.
5) Protection against high environmental temperature
ESE-GY series of energy-saving high-voltage system has built-in multi-point temperature detection circuit to ensure the operation of energy-saving high-pressure system in normal temperature environment.
6) Power unit bypass function
if some power unit breaks down, the system can bypass it and keep operating with lower high voltage energy saving system load capability.
7) Urban electricity bypass switch
By the urban electricity bypass switch circuit, it can form a drive-motor with double power supplies.
