Electric operating mechanism of outdoor AC high-voltage segregate switch

Abstract

Disclosed is an electric operating mechanism for outdoor AC high-voltage insulating switches, which effectively solves the problem of large force moment and long braking time on current manual operating mechanisms. The electric operating mechanism comprises a chest and a mechanical driving device, an electric control device and a manual-electric closedown device, which are arranged inside the chest. The technical proposal lies in that: driving teeth, a clutch internal tooth sliding sleeve and a duplicate gear sleeve, are arranged on a transmission shaft of the mechanical driving device, on which a worm wheel is fixed; the duplicate gear sleeve is meshed with a gearwheel on an output shaft; the peripheral retaining boss is wedged with a transmission fork which is driven by a crank shaft and is controlled by a hand shank. The hand shank is used to control the transmission fork to enable the clutch internal tooth sliding sleeve to disengage or mesh with the duplicate gear sleeve. The electric operating mechanism is reasonable in structure, flexible and convenient to operate manually with a speed equal to that when being operated electrically; the electric operating mechanism can close or open the brake quickly, thus remarkably prolonging the service life of the inductive contact and the sensing finger, and improving operational safety and stability.

Description

technical field [0001] The invention relates to an electric operating mechanism for opening and closing of a high-voltage isolating switch, in particular to an electric operating mechanism for an outdoor AC high-voltage isolating switch with flexible and convenient operation, labor-saving, safe and reliable operation, and rapid action response. It belongs to the field of high-voltage electrical equipment supporting equipment. Background technique [0002] At present, with the continuous improvement and rapid development of the technical level of outdoor AC high-voltage disconnectors, as well as the market demand, it is increasingly urgent to improve the performance of various operating mechanisms that match it. The electric operating mechanism for opening and closing of the high-voltage isolating switch has become a widely used operating mechanism that uses the motor as the operating power to realize the operation of the isolating switch. However, no matter what kind of ope...
