Embodiment Construction
[0015] Now in conjunction with the accompanying drawings, the structure of the present invention will be further described. Such as Figure 1-Figure 3 As shown, the auxiliary switch smooth action structure includes output shaft 1, splint 2, bearing 3, auxiliary switch bracket 4, transmission gear 5, auxiliary switch rotating gear 6, auxiliary switch 7, A-shaped flat key 8, and the two ends of the output shaft Bearings are respectively provided, that is, the output shaft is installed between the splints through the bearings at both ends, the output shaft is fixed into a whole by the A-shaped flat key, the output shaft is fixed to limit the rotation, and one end of the output shaft protruding from the splint is connected with the transmission gear. Its structure is as follows: the transmission gear is a gear part with a fan-shaped tooth opening on one side, the auxiliary switch on one side of the transmission gear is installed on the auxiliary switch bracket, and the auxiliary s...

The invention relates to a smooth operation structure of an auxiliary switch of an operating mechanism and a working principle thereof so that technical problems that the rotation stability and reliability of the auxiliary switch are poor and the correct normally-open and normally-closing switching is inaccurate during the usage process of the existing same kind of products can be solved. Two endsof an output shaft of an auxiliary switch smoothing structure are installed between clamps; and one end of an output shaft extending out of the clamp plate is connected with a transmission gear. Thetransmission gear is a gear member having one side with a fan-shaped gear mouth; the auxiliary switch at on one side of the transmission gear is installed at an auxiliary switch bracket; an auxiliaryswitch rotation gear is arranged at the auxiliary switch and is engaged with the transmission gear; and the auxiliary switch rotation gear is installed at the auxiliary switch through a central squarehole and an integrated unit is formed by positioning with a positioning hole formed in a gear step. The transmission gear rotates by the output shaft to drive the transmission gear to rotate at a corresponding angle; and the auxiliary switch is driven to make rotation, wherein the auxiliary switch makes ormally-open and normally-closing switching at a rotation angle of 90 degrees.
Description
technical field [0001] The invention relates to the mechanical principle in the mechanical high-voltage switch industry, and relates to a stable action structure and working principle of an auxiliary switch of an operating mechanism. Background technique [0002] The auxiliary switch of the operating mechanism is a function of switching the power supply and taking signals when the circuit breaker is in the opening and closing state. For example, the application number 201310134725.5 disclosed in the Chinese patent literature, the application publication date is 2013.08.21, the invention name is "a circuit breaker opening position locking device"; when the circuit breaker opening position locking device is in the unlocked state, the opening position is locked The pin passes through the first locking hole of the circuit breaker operating mechanism frame and keeps a certain distance from the closing trigger. At this time, the closing trigger can be triggered and the circuit bre...
