【摘要】：随着人们的生活水平的提高,社会生产以及人民的生活越来越离不开电的使用,正是因为现在对电能的高度重视,供电的可靠性要求也越来越高,促使各种高低压电器保护功能更趋完善。塑壳断路器作为低压电器中的一员,也得到了飞速的发展,特别是塑壳断路器中的脱扣器技术发展尤为迅速,早在六十年代初国外就研制出了断路器用电子式脱扣器,至今已经历了几代产品的更新。近年,由于电子技术的发展,进一步推动了电子脱扣器的技术革新。本文主要研究电子脱扣器的设计,本文从实际工程应用中对电子脱扣器的需求出发,描述了电子脱扣器所需要达到的基本技术指标,并以此技术指标为依据,展开了电子脱扣器的软、硬件设计。硬件设计主要为采样系统设计(包括电路仿真)、电源系统设计、MCU系统设计;软件设计主要为主程序及各功能程序的框图设计,同时为了提高系统可靠性,进行了电子脱扣器的EMC设计。通过对电子脱扣器的硬件设计、软件设计、电磁兼容设计等,得到了一个能够进行实际工程应用的脱扣器产品。通过上述设计方法得到的电子脱扣器,性能优越、可扩展性及环境适应能力强、电磁兼容性能好。完成相关设计后,把电子脱扣器应用于塑壳断路器,进行实物测试,并编制了相关通信测试软件。经过测试证明,以文中设计方案为基础的电子脱扣器能够满足塑壳断路器的要求,可以进行推广。
[Abstract]:With the improvement of people's living standards, social production and people's lives are becoming more and more inseparable from the use of electricity. It is precisely because of the high attention to electric energy that the reliability of power supply is becoming more and more high, and the protective function of various high and low voltage electrical appliances is more perfect. The rapid development, especially in the plastic case circuit breaker, has been developing rapidly. Early in the early 60s, the electronic release device for circuit breakers was developed abroad. It has been updated for several generations. In recent years, the technical innovation of electronic release is further promoted because of the development of electronic technology. This paper mainly studies the electronics. The design of the tripping device is based on the requirement of the electronic tripping device in the practical engineering application, and describes the basic technical indexes that the electronic release device needs to achieve. Based on this technical index, the software and hardware design of the electronic release device is developed. The hardware design is mainly designed for the design of sampling system (including circuit simulation), the design of power supply system, M CU system design; the software design is mainly the main program and the block diagram of each function program. At the same time, in order to improve the reliability of the system, the EMC design of the electronic release is carried out. Through the hardware design, software design and electromagnetic compatibility design of the electronic release device, a release product which can be applied to practical engineering is obtained. The electronic tripping device obtained by the design method has excellent performance, extensibility, strong adaptability to the environment and good electromagnetic compatibility. After completing the related design, the electronic release device is applied to the plastic shell circuit breaker to carry out the physical test, and the related communication testing software is compiled. The test proves that the electronic release based on the design scheme is based on the test. The device can meet the requirements of moulded case circuit breakers and can be popularized.
