基于DSP的GIS断路器的在线监测前置采样及报警模块的设计

Design of Pre-Sampling of Online Monitoring GIS Breaker and Alarm Module Based on DSP

摘要: 随着电力系统朝着高压、大容量的方向发展，保证电力设备的安全运行越来越重要。高压断路器是电力系统中重要的电气设备，在电网中起到控制和保护作用，因此确保断路器的可靠性运行极为重要。对断路器实行的定期检修制度盲目性大，并且容易引入新的故障隐患，降低设备的可靠性。因此必须对高压断路器状态实行在线监测，实时监测断路器的运行状态，并为设备的状态检修提供依据。本文基于DSP2812设计了GIS断路器的在线监测前置采样及报警模块，目前已应用于GIS断路器的在线监测系统，并在电力生产运行中取得预期效果。

Abstract: Considering the development of electric power system turns to high voltage and great capability, keeping the electric equipments in safe operation becomes more and more important. High voltage circuit breaker (HVCB), as one of the most important electric equipments in electric power system, is used to control and safeguard electric power system, so making it work credible is very important. The traditional scheduled maintenance to breakers is inefficient and always causes faults by the maintenance itself. Therefore, Condition Based Maintenance (CBM) based upon condition monitoring is necessary and the running conditions of the HVCBs should be monitored on line in real time which can supply the basis for Condition Based Maintenance. Pre-sampling of the online monitoring GIS circuit breaker and alarm module are designed based on DSP2812 in this paper. At present, GIS circuit breaker has been applied to the online monitoring system, and to achieve the desired results in the electricity production.
