在现在工农业生产中,病虫害是科学研究中非常棘手的一项难题。传统的化学杀虫剂不仅杀虫效果不佳,而且对环境卫生、食品安全、人类健康等都有很大的不利影响。所以,洁净、安全的物理灭虫法的研究与设计就显得特别的必要,高压静电灭虫器的研究与设计就是在这种环境与条件下产生的。
本毕业论文研究和分析了高压静电的产生方法,并根据实际选择合适方案。由此来选择所需的电器元件和零件,设计灭虫器的主电路、控制电路、工作电路等。最后在设计基础上,将电器元件组成的电路集成到一块电路板上,将控制开关、电源等布置到合适位置,把工作装置设计成有益于人们应用的形式。
另外,在电学部分设计完成后,为灭虫器设计一个大小、重量、材料、形状合适的外壳,使其既实用又安全。
论文的研究结论有:
利用SG3525控制逆变电路可将直流电流转化成震荡的交流电,再通过MOSFET提高震荡频率。
利用普通变压器将低压高频交流电升压为较高压交流电流,倍压电路又将其进一步升压,并转化为高压直流静电,用于杀灭害虫。
为了提高杀灭害虫的功效,和杀灭不同植物上的害虫,高压灭虫器的高压探头可设计成不同形状的多电极的探头。
高压灭虫器的外壳为塑料材料制作的喷雾器结构形状。
本毕业设计特点与创新:
从环境和健康的话题出发,提出创新的杀虫方法,符合当今社会的可持续发展原则;
应用了电力电子技术中的PWM技术、逆变技术、倍压升压原理和SG3525、MOSFET、高压包等集成电学芯片等。
综合应用了机械、电工、电子、模具设计等多学科的专业知识。

Research and Design of High Voltage
Electrostatic Insect Killer
ABSTRACT
In the present industrial and agricultural production, pest and disease is a scientific research very difficult problem. Not only killing the traditional chemical pesticides ineff - ective, but also for environmental health, food security, human health has a significant adverse effects. So, clean, safe pest control method of the physical and design is parti- cularly necessary, pest control device of high voltage electrostatic and design is in this environment and under the conditions generated.
In this thesis I researched the method of high voltage static electricity, select the appropriate program according to the actual. As to select the required ponents and parts, designed for insect killers main circuit, control circuit, the working circuit. Finally , based on the design, ponents integrated circuit board, the control switch and power supply were arranged to the right location, the working device was designed to benefit people in the form of application.
Thesis concluded that:
Using Inverter circuit controlled by SG3525,DC can be changed to Concussion current. Through the mosfet improve concussion frequency.
By mon low-voltage high-frequency ac transformer will boost for high-pressure ac
