Background

The programming operation is an integrated operation process driven by a power grid and is an important component of smart power grid construction. In the programmed operation process, the opening and closing of the open type disconnecting link can send information to the dispatching through the auxiliary node, and the dispatching personnel can judge whether the disconnecting link is in place or not through the information. However, the information is generally sent by a motor of the disconnecting link transmission mechanism, and the transmission mechanism sends switching-on and switching-off information due to the problems of jamming, disjunction and the like of the disconnecting link transmission mechanism, so that the knife edge of the disconnecting link is still not switched on and off in place. Therefore, the dispatcher can make a judgment only by requiring experienced operators to check the switching-on and switching-off conditions of the disconnecting link on site. The problem not only has wasted the manpower, relies on the artificial experience to judge the switch on-off condition moreover, can't guarantee the accuracy of switch on-off of switch, consequently can save the human cost to switch on-off position decision device is installed to the switch, can also be more accurate judge switch on-off state, improve the security of equipment operation. In the case of an open-type knife switch during operation, the opening/closing position determining device mounted on the knife edge is in a high-voltage and high-current environment. On one hand, the interval of the opening and closing actions of the disconnecting link is more than one year every time, and the judgment device can be used for timely and effectively judging only by supplying power for a long time. On the other hand, the determination device is in a high-voltage, high-current environment that does not allow frequent battery replacement. A well-designed power supply system is necessary to ensure the validity of the determination device.
