Design On The Transformers Automatic Switching Device In 220KV Transformer Substations

The paper, according to the using request of on-the-spot project of transformer, completely analyzes the running condition and function request of transformer change-over equipment, and brings to overall design project of change-over equipment. Aiming at the concrete design characteristics of the equipment, this article advances design project of hardware which uses 80C196KB single-chip microcomputer to make up structure of many CPUs, and we can adopt distributive, blocking design project of software to satisfy the high dependable and safe require of the equipment. This text demonstrates in detail design project and idea of equipping hardware and software, and their accuracy, simulation and static experiment in laboratory, locale experiment and practical function checkout on-the-spot. The investigation of this task resolves problem that two main transformers can substitute for each other in large transformer substation, so consumedly increase supply dependability and circulating economy of transformer substation.HE Run-ming(electrical engineering)Directed by prof.
