Double-power-source automatic transfer switching equipment

Abstract

The invention discloses double-power-source automatic transfer switching equipment which comprises a fixing seat, an end cap and a handle. A main circuit breaker and a standby circuit breaker are arranged on two sides of the fixing seat respectively, a handle groove for allowing the handle to rotate is formed in the end cap, a stirring seat is arranged above the fixing seat, a clutch motor is arranged on the fixing seat, two transmission plates are hinged on a mounting frame, one ends of the transmission plates are hinged to the stirring seat, two cams in one-to-one correspondence to the transmission plates sleeve a rotating shaft of the clutch motor in a linkage manner, a driving groove matched with a driving end of the corresponding cam is formed in each transmission plate, one side of each driving groove outwards extends to form a concave-arc-shaped driving wall, the handle sleeves the end of the rotating shaft of the clutch motor, and after pressing the rotating shaft on the clutch motor, the handle can drive the rotating shaft to independently rotate movably. The double-power-source automatic transfer switching equipment has the advantages of being convenient and labor-saving in manual operation, stable and reliable in working and high in sensitivity.

Description

technical field [0001] The invention relates to the field of a circuit breaker, in particular to a dual power supply automatic transfer switching appliance. Background technique [0002] The purpose of the dual power automatic transfer switch is to put it simply as one common and one backup. When the common power suddenly fails or fails, it will be automatically switched to the backup power through the dual power switch. (The backup power can also be powered by a generator under small loads ,) to allow the device to still function normally. The dual power automatic transfer switch generally includes a motor. The shaft of the motor drives the automatic switching transmission device of the double circuit breaker switch to realize the conversion of the circuit breaker switch. A handle for manual driving is also set on the shaft. Once the motor fails, the handle can be used to drive the switch. Conversion work, because the handle is fixedly sleeved on the rotating shaft, the po...

AI Technical Summary

Problems solved by technology

The dual power automatic transfer switch generally includes a motor. The shaft of the motor drives the automatic switching transmission device of the double circuit breaker switch to realize the conversion of the circuit breaker switch. A handle for manual driving is also set on the shaft. Once the motor fails, the handle can be used to drive the switch. For conversion work, since the handle is fixedly sleeved on the rotating shaft, the position of the rotating shaft in the motor is the rotor assembly. When the handle is driven, it is extremely laborious, which is not conducive to the convenience of operation.

[0003] And the double circuit breaker switch automatic switching transmission device is used to control two circuit breakers alternately on and off, the existing double circuit breaker switch automatic switching transmission device includes a fixed plate, and the fixed plate is provided with a motor, on the rotating shaft of the motor The sleeve is equipped with a rotating arm, and the two ends of the rotating arm are respectively hinged with a toggle seat, and the toggle seat is provided with an accommodating cavity for the switch of the circuit breaker. The motor drives the rotating arm to rotate to realize the switch on and off of the two circuit breakers. In this structure, slippage is likely to occur between the rotating arm and the motor shaft, and the motor is relatively difficult to rotate, which may easily cause the circuit breaker switch to not be turned on and off due to unstable work, posing a safety hazard
