非程控式电压互感器负荷箱档位切换装置设计
|
摘要
介绍在进行现场电压互感器检定时,负荷箱作为提供二次负荷的设备需要放置于被试互感器下方,每进行一次负荷切换都需要人工完成。而进行试验的位置离负荷箱的距离随电压等级的升高而增加,使得在进行该项试验时需要花费较长时间来进行负荷更换,严重影响其工作效率。根据使用现状设计了一种远程装置,可有线或者无线遥控来操作负荷箱的档位切换从而完成现场互感器检测,极大提高现有工作效率和降低现场试验的安全风险。
In the field voltage transformer test, the load box needs to be placed under the transformer as the second load to provide the equipment, a load switching need to be done manually each time. And the distance of the test location from the load box increase as voltage level increases, lead to the test takes a long time to carry out the load replacement, seriously affecting its efficiency. Therefore, this paper designs a remote device based on the use of using status, it can operate the load box by wire or wireless remote control to switch the field transformer detection, greatly improve the existing work efficiency and reduce the safety of field testing risk.
