Abstract
The invention discloses a stage-type load switch operation mechanism. The stage-type load switch operation mechanism comprises a front support plate, a rear support plate, an operation shaft, a two-sectional switch-on output crank arm, a switch-on trip limiting shaft, a switch-on trip interlock crank arm, an interlock rotating shaft, an interlock plate, a switch-on trip position plate, a switch-off trip rotating shaft, a switch-off energy storage position rotating shaft, a gear set, a mechanism driving rotating shaft, a switch-on spring and a switch-off spring. The switch-on stroke is divided into two stages, in a first stage, the switch-on spring does not store energy, and a mechanism output shaft rotates along an operating shaft of an operation mechanism; in the second stage, the switch-on spring stores energy in compression, the mechanism output shaft does not rotate until the energy storage mechanism trips away, the switch-on spring releases energy to drive the mechanism output shaft to rotate in acceleration so as to drive the load switch to switch on. The stage-type load switch operation mechanism has fewer parts and is simple to assemble; the output capability of the switch-on spring of the operation mechanism is optimized through the stage-type operation.
Description
Technical field
The present invention relates to a kind of on-load switch operating mechanism, particularly disclose a kind of segmented on-load switch operating mechanism.
Background technology
On-load switch is a kind of device for switching between circuit breaker and isolating switch, has simple arc-control device, can cut off the rated load electric current, but can not cutting-off of short-circuit electric current.The on-load switch operating mechanism then is by the energy storage of spring and the action of charge releasing belt dynamic load switch spindle, realizes the combined floodgate of on-load switch and a cover mechanical device of separating brake.
In at present popular on-load switch pattern, often understanding some on-load switch needs stroke very big because of the on/off switch that needs of arc extinguishing stroke, and normally the angle that need rotate of main shaft is very big.Contact counter-force or resistance that we are bigger when needing spring to have enough power outputs to overcome on/off switch when knowing the on-load switch on/off switch, in order to increase mechanism's power output, a kind of is the overstriking spring diameter, another kind is the radius (just increasing arm of force length) that increases the combined floodgate output toggle arm, when spring diameter since mechanics limit can't continue to increase, that just can only be by increasing the radius of mechanism's combined floodgate output toggle arm, but increase the arm of force and also just mean the impulse stroke that can increase spring, such as angle of same rotation, A connecting lever radius is 50mm and B connecting lever radius 100mm, and their spring impulse stroke differs one times.Just one side B connecting lever has satisfied the requirement of power output, but but the spring free length of finding the B connecting lever simultaneously on the other hand is A connecting lever spring free length one times (because will satisfy the spring impulse stroke), the increase that long spring length just means mechanism's overall dimensions has brought difficulty to design.And on the other hand, the length of spring compressed stroke increases, stored energy increases, mean that intake also increases, after energy discharged, unnecessary energy can not make switch combined floodgate performance better, opposite on-load switch is after becoming acceleration through wide-angle, it is big that closing speed becomes, even the closing speed of the switch regulation that overloads, and causes contact to wear and tear because of high-speed impact or accidents caused.
Summary of the invention
The objective of the invention is at above-mentioned problems of the prior art, propose a kind of segmented and meet switch operating mechanism, by making process being divided into two sections, reduced the spring impulse stroke, make the requirement to satisfy mechanism's power output with less relatively switching-in spring, reduced input work simultaneously and satisfied the requirement of closing speed.
The present invention is achieved in that
