Abstract

The invention discloses an operating mechanism and a load switch with the same, and solves the problems that the operating mechanism of the conventional load switch is relatively complex, and chain wheels and a chain on the operating mechanism are easy to damage. The load switch comprises the operating mechanism and an arc extinguishing device, wherein the operating mechanism comprises an operation main shaft and a driving motor; a first chain wheel is arranged on the operation main shaft; the driving motor is in transmission connection with the first chain wheel; a mounting plate, a driving disc and a stroke plate are arranged on the operation main shaft; a driving part is arranged on the first chain wheel; a sliding block is arranged on the driving disc, and has a first position on which the driving part is clamped with the sliding block to drive the driving disc connected with the operation main shaft in a linking manner to rotate and a second position on which the sliding block is separated from the driving part to enable the first chain wheel to idle. The driving disc is adopted to drive the operation main shaft to rotate, the two positions of the sliding block are utilized to ensure that the first chain wheel idles when the driving motor stops, and avoid the damage of the first chain wheel and the other parts.

Description

technical field [0001] The invention relates to a load switch, in particular to an operating mechanism and a load switch provided with the operating mechanism. Background technique [0002] The load switch is a switching device between the circuit breaker and the isolating switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current. Next, the main shaft rotates clockwise. On the one hand, the piston moves upward through the slider crank mechanism to compress the gas; on the other hand, the main switch knife is opened first through the transmission system composed of two sets of four-bar linkages, and then the arc extinguishing gate is pushed. The knife opens the arc contacts, and the compressed air in the cylinder blows out the arc through the nozzle. The operating mechanism of the existing load switch is usually complex in structure, and usually includes a motor, an operating spindle, a sprocket, a transmission ...
