摘　　要： 针对电力设备外绝缘子污闪问题,设计了一套监测系统,重点分析了系统的总体方案、软硬件设计。其中,在软硬件设计过程中,采用了面向对象的模块化设计思想和分层分布式的系统结构方法。另外,在设计中采用两级变送方法以提高绝缘监测系统的测量精度及可靠性。后经测试证明,该系统精度高、抗干扰能力强,完全达到了设计要求。 For flashover at external insulator of electrical equipment, a set of monitoring system is designed. The paper analyzes the general scheme and software ＆ hardware design of the system, in which the design concept of object-oriented modulus and the method of lamination and distribution system structure are applied. In addition, the 2-level transformation and transmission method is used in design to increase the measurement accuracy and reliability of insulation monitoring system. The system has been proved to have high accuracy and strong capability against interruption, and completely meet the design requirements.
