Description
Technical field
The present invention relates to a kind of dual-power transfer switch, particularly relates to screw drive formula dual-power transfer switch.
Background technology
In order to realize the conjunction of two breaker of plastic casing point conversion, the double power supply automatic transfer switch well known at present is driven
Mechanism has plenty of the pushing that both sides are driven by drive disk, and drive disk rotates under the drive of motor, and the pushing of both sides is each
If doing near linear slip from along the individual support round platform of alinement, why current be referred to as approximate straight line motion, because
Fit clearance is needed for pushing and support round platform, and in order to ensure stroke, the track length of pushing is long, and pushing exists
In the course of work, the power being subject to is bigger, can not all ensure that pushing moves along a straight line in theory；In addition, pushing and back-up ring
Between there is also certain interval, only can not ensure pushing in the case of stress toward upwarping by these back-up rings.Thus make
Into the design margin " being eaten up " of stroke, the difficulty that can not detain or close a floodgate again after circuit breaker tripping is easily caused.Moreover with turn
The work times for changing device for switching rise, and the abrasion between pushing and support round platform can be increasing, causes gap further to add
Greatly, it is increasing to ultimately result in the possibility that can not again detain and can not close a floodgate；But in turn, increase the design margin of stroke, meeting
When causing the breaker closing particularly to detain again, the active force between handle and pushing is very big, and this can cause motor to can't bear weight
Negative reduction of service life or handle fracture；In addition, the pushing of currently known dual-power transfer switch electrical equipment can flirt
Condition is：It is 1. not adjustable；2. it can adjust, but it is adjustable only to detain direction again；3. fastening lock again can adjust, but both are not mutually only
It is vertical, related adjustment（It can cause to detain stroke and combined floodgate stroke contradiction again）, and adjusting screw is that axis is vertical in top handle
Alignment handle, but oblique, this strength and stiffness to threaded connection can bring detrimental effect.
