Manual button device of operating mechanism and operating method thereof

Abstract

The invention relates to an operating mechanism manual button device and an operating method thereof. The device and the method are designed to solve the technical problem that the existing similar operating mechanism manual switching-on / off structure in high-voltage switch products is poor is design and poor in stability. One ends of push rods of switching-on and switching-off manual button assemblies of the manual button device respectively face the turning ends of a manual switching-on push plate and a manual switching-off push plate. The operating mechanism manual button device is characterized in that the switching-on and switching-off manual button assemblies respectively comprise two button push plates, a connecting rod, a tension spring, a push rod, and a button bracket. In the manual switching-on process, the button push plates are pressed, the button push plates drive a first pin shaft and a second pin shaft to push inward along a transverse guide rail slot of the button bracket, the second pin shaft drives one end of the connecting rod to push inward along the transverse guide rail slot of the button bracket, the other end of the connecting rod drives a third pin shaft to push downward along a longitudinal guide rail slot of the button bracket, the tension spring is pulled open and the push rod is pushed to push downward, the other end of the push rod contacts the manual switching-on push plate, and the manual switching-on push plate rotates around the center of a switching-on half shaft to realize switching-on.

Description

technical field [0001] The invention relates to a manual button of an operating mechanism in a high-voltage switch, in particular to a manual button device for the operating mechanism and an operating method thereof. Background technique [0002] A high-voltage switch, or a high-voltage circuit breaker, can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. Perfect arc extinguishing structure and sufficient breaking capacity. The operation process mainly involves controlling the three stations of closing, opening and grounding of the high-voltage switch. That is, when the operating mechanism is in the closing position, the grounding operation cannot be performed; when it is in the grounding position, the closing operation cannot be performed; thus Ensure the safety of the operating mechanism of th...
