高压隔离开关与远程监控自动化的研究

Study on High-Voltage Isolation Switch and Remote Monitoring Automation

辽宁电科院虎石台高压试验场大容量实验室原隔离开关为40.5 k V气动操作机构。冬季受气温影响,气路系统易产生漏气,导致气体压力不足,无法实现正常的合、分闸操作,试验过程中存在很多安全隐患。因此,根据现有隔离开关的基本情况,为降低改造成本,在原有开关主体结构不变的条件下,研究一种采用交流电机旋转传动的操动机构,代替气缸实现操作,并通过控制器与上位机通信,实现操作人员对隔离开关进行远程操作与监控,满足试验需要,确保安全生产。

Hushitai high voltage laboratory testing ground for large-capacity original isolation switch is 40. 5 k V pneumatically operation mechanism. In winter,gas system affected by temperature is easy to leak,this results can lead to insufficient gas pressure,unsuccessfully normal closing and opening operations,there is the hidden trouble for test. According to the basic situation existing isolation switch,a rotating AC motor drive actuator instead of the cylinder is studies which can to reduce costs. The operators also achieve isolation switch for remote operation and monitoring to meet the test needs and safe production.
