The invention discloses a linkage device, a linkage reset switch and a reset switch linkage method. The linkage device comprises a plurality of induction switches, a controller, a first clamping device, a second clamping device, a first linkage coil, a second linkage coil and a linkage mechanism. The first connecting rod and the second connecting rod are coaxially arranged; the head end face of the first connecting rod is machined into an inclined face. The first linkage coil is arranged on the head of the first connecting rod. The head end surface of the second connecting rod is processed into an inclined surface; the first linkage coil is arranged at the head of the second connecting rod; the outer wall of the tail of the first connecting rod is a non-cylindrical surface; the outer wallof the tail of the second connecting rod is a non-cylindrical surface; the inductive switches are used for feeding back signals to the controller, and the first clamping device, the second clamping device, the first linkage coil and the second linkage coil are controlled based on the controller. The linkage device can carry out linkage operation on two adjacent groups of reset switches so as to solve the problem that the two groups of reset switches do not move synchronously.
Description
technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a linkage, a linkage reset switch and a reset switch linkage method. Background technique [0002] During the operation of the substation, secondary circuit breaker trips often occur, partly because of the short circuit of the circuit, and most of the reasons are due to human error or mechanical vibration, etc. If the motor power circuit breaker is disconnected by mistake , may cause the switch to refuse to move, which greatly affects the safe operation of the power grid. The function of the reset switch is a switch used to determine whether the switch action is normal. The reset switch will automatically switch back to the closed state when the switch operation is abnormal. [0003] Correspondingly, there is a certain correlation between different return switches. If a return switch is disconnected due to a short circuit in the circuit, in order to ensure the...
