Timing Coordination Analysis of 35 kV VN1 Type Switch Handcart Reclosing Signal and Interlocking Auxiliary Switch Action
According to the five prevention requirements,the opening and closing of the handcart will be locked based on the handcart position and switch status.Taking a reclosing failure accident of a 35kV VN1 type switch as an example,this paper explores the reclosing signal and timing coordination of the locking auxiliary switch of the switch handcart,and proposes a solution for similar faults in the switch handcart.
