Design And Manufacture

DC high voltage amplifier is one of the important components to support of PVDF thin films polling equipment. Hardware polling is a very important tool in the characterization of PVDF thin films to increase piezoelectric properties. The existence of the problem will be difficult to obtain a high voltage DC sources of lead in the market encouraged us to design and create high-voltage DC source. In research that has been done I've been able to design and create high-voltage amplifier 30 KV DC as a producer of high electric field. To validate the performance of this high voltage DC amplifier has created further testing and measuring the output voltage. Testing is performed to determine the precision, accuracy and stability of the output voltage of the amplifier for more than 60 minutes. From the test results and output measurements performed show that the relative error of 4.5%. Tool output stability is good enough for a span of 30 minutes. This indicates that the design and manufacture of high DC voltage gain have been successful.   Keywords: DC Amplifier, Electric field, High voltage, Polling, PVDF Film

Sine Signal

According to driving requirements of single-chamber and single-vibrator piezoelectric pump, a program-controlled driving power supply is designed. The power supply first utilizes D/A converter and voltage-controlled oscillator to generate sine signal with adjustable frequency, then it changes the amplitude of signal by T-type resistor network. At last, it utilizes high-voltage amplifier and power amplifier to obtain a high voltage and a large current to realize drive of piezoelectric pump. Output voltage and frequency of power supply can be adjusted under control of program. Prototype of driving power supply is manufactured and its output performance is test. Experimental results show that, in power supply, waveform of the sine signal is satisfying, range of output voltage is 0-170V and range of output frequency is 5-600Hz. Power supply designed meets the driving requirements of piezoelectric pump, and also has merits of small size, light weight and low cost.

The Stability

As for the wide application of arc suppression coil to the grounding in neutral point of mine high voltage grid, grid leakage fault rules and harmonic characteristics of the neutral point grounding system through arc suppression coil are analyzed, the selective leakage protection program “zero-sequence voltage starts, fifth harmonics of grid zerosequence voltage and zero-sequence current are extracted for phase comparison” is proposed, and corresponding fifth harmonic extraction circuit and power direction discrimination circuit are designed. The experimental results show that the protective principle applies not only to the neutral point insulated power supply system, but also to the power supply system in which neutral point passes arc suppression coil, which can solve selective leakage protection problems under different neutral grounding ways, improving the reliability of selective leakage and guaranteeing the stability of the action value.
