10kV开关柜开锁方法、装置及系统
摘要：
一种10kV开关柜开锁方法、装置及系统，其中，所述方法包括：获取高压带电显示装置的信号；判断高压带电显示装置是否带电；如果判断为无电，则输出用于表征对开关柜进行开锁并控制接地刀闸闭合的开锁信号；否则，输出用于表征对开关柜进行强制闭锁的闭锁信号。通过判断高压带电显示装置是否带电，在无电时，输出用于表征对开关柜进行开锁并控制接地刀闸闭合的开锁信号，否则，输出用于表征对开关柜进行强制闭锁的闭锁信号。由于对高压带电显示装置的带电与否判断后进行开闭锁操作，确认无电才允许开锁，从而减低了误操作概率，使变电站中压开关柜的防误操作从技术上得到了保证，进一步确保了操作人员的人身安全，以及电网系统、设备的安全。
摘要（英）：

A 10kV switch cabinet unlocking method, device and system. The method includes the steps of: obtaining a signal of a high-voltage electrified display device; judging whether the high-voltage electrified display device is electrified; if the device is judged to be not electrified, outputting an unlocking signal representing that unlocking is performed on a switch cabinet and a grounding knife switch is controlled to be closed; otherwise, outputting a locking signal representing that forced locking is performed on the switch cabinet. By judgment of whether the high-voltage electrified display device is electrified, when the device is not electrified, the unlocking signal used for representing that unlocking is performed on the switch cabinet and the grounding knife switch is controlled to be closed is output, otherwise the locking signal used for representing that forced locking is performed on the switch cabinet is output. Since unlocking and locking operation is performed after judgment of whether the high-voltage electrified display device is electrified, unlocking is only allowed when the device is confirmed to be not electrified, thereby reducing the probability of misoperation, technically guaranteeing misoperation prevention of a medium-voltage switch cabinet of a transformer station, and further ensuring personal safety of operating personnel and safety of a power grid system and equipment.
