Description
Technical field
The present invention relates to a kind of emergency opening/closing operation mechanism of high-voltage switch equipment, belong to withdraw-type switching device technical field.
Background technology
High-tension switch cabinet is made up of control room, breaker chamber, bus-bar room and cable vault conventionally, is fixed with one group of fixed contact pedestal as static contact head device in the chamber of breaker chamber, connecting with extraneous high-voltage power circuit into and out of line fixed contact on fixed contact pedestal.In circuit breaker chassis pushes breaker chamber time, the upper and lower contact of circuit breaker cart engages respectively with into and out of line fixed contact, after breaker closing, realizes the connection on circuit.At circuit breaker manual operation handcart advancing mechanism, circuit breaker cart is closed a floodgate from test position is pushed into service position, or after separating brake, circuit breaker cart is retracted into test position from service position.And the divide-shut brake of circuit breaker is to control by divide-shut brake operating mechanism, therefore the operating mechanism of each circuit breaker is all furnished with urgent divide-shut brake button, be in an emergency, make operating personnel without opening under the prerequisite of cabinet door, can carry out the breaking-closing operating of circuit breaker, the urgent divide-shut brake button of most circuit breaker is the end plate that switch cubicle is installed, and therefore exists staff and touches the accident potential that causes circuit breaker misoperation by mistake.
The urgent switching off/on device of circuit breaker as disclosed in CN201413946Y, mainly by lever bracket, cabinet door bracket, opening button, runner, bearing pin, switch knob, closing operation bar stage clip, closing operation bar, sub-switching operation bar, sub-switching operation bar stage clip structure, lever bracket is hinged on cabinet door bracket by bearing pin, runner is fixed on bearing pin, be arranged on the cabinet door bracket of cabinet door inside and be respectively equipped with switch knob or opening button, and in lever bracket, be separately installed with closing operation bar and sub-switching operation bar, be sleeved on the both sides, front and back that closing operation bar stage clip on closing operation bar and sub-switching operation bar and sub-switching operation bar stage clip withstand on respectively lever bracket, make lever bracket energy half-twist by runner, make switch knob and opening button corresponding with one end of closing operation bar and sub-switching operation bar, by operating respectively switch knob or opening button, in the situation that need not opening switchgear cabinet door, just can control combined floodgate or the sub-switching operation of circuit breaker.But above-mentioned urgent close/open machine is in a lever bracket, to be separately installed with closing operation bar and sub-switching operation bar, in the time of rotating wheel, lever bracket only has two positions, a position is parallel with cabinet door after closing operation bar rotates with lever bracket with sub-switching operation bar, although can operate switch knob or opening button, can not control closing operation bar and sub-switching operation bar due to switch knob or opening button, therefore can not realize circuit breaker emergent switching on-off operation; In the time that lever bracket is vertical with cabinet door, switch knob and opening button corresponding with on closing operation bar and sub-switching operation bar and cabinet door bracket simultaneously, therefore switch knob or opening button can be operated and closing operation bar or sub-switching operation bar can be controlled, also because can control closing operation bar or sub-switching operation bar simultaneously, still there will be and touch knob phenomenon by mistake, therefore there is accident potential.
Summary of the invention
The object of this invention is to provide one rational in infrastructure, can thoroughly solve and touch divide-shut brake knob by mistake, improve the emergency opening/closing operation mechanism of high-voltage switch equipment of processing safety.
The present invention is that the technical scheme achieving the above object is: a kind of emergency opening/closing operation mechanism of high-voltage switch equipment, it is characterized in that: comprise control handle, opening button, switch knob and upper ejector pin and lower push rod, described opening button, control handle and switch knob are arranged on supporting plate, and control handle is arranged on the middle part of opening button and switch knob, the inner side of control handle is connected with plate, two connecting plates up and down of upper rotary support plate are hinged on supporting plate by bearing pin and the upper rotating shaft of coaxial line respectively, its two ends of torsion spring that are enclosed within rotating shaft are connected with supporting plate and upper rotary support plate respectively, be fixed on upper backing pin in rotating shaft corresponding with the upper driving lever of plate, the upper ejector pin of horizontally set is arranged on the upper head plate and upper spacer of rotary support plate, the both ends of the spring being sleeved on upper ejector pin withstands on respectively on the shaft shoulder of upper head plate and upper ejector pin, when upper ejector pin and the same axis of opening button, the two ends of upper ejector pin are corresponding with the separating brake switch on opening button and circuit breaker panel respectively, two connecting plates up and down of lower rotation supporting bracket are hinged on supporting plate by lower rotary shaft and the bearing pin of coaxial line respectively, its two ends of torsion spring that are enclosed within on lower rotary shaft are connected with supporting plate and lower rotation supporting bracket respectively, the pole pair of setting aside that is fixed on lower backing pin on lower rotary shaft and plate should, the lower push rod of horizontally set is arranged on the bottom plate and lower clapboard of lower rotation supporting bracket, the both ends of the spring being sleeved on lower push rod withstands on respectively on the shaft shoulder of bottom plate and lower push rod, when lower push rod and the same axis of switch knob, the two ends of lower push rod are corresponding with the closing switch on switch knob and circuit breaker panel respectively.
The present invention is hinged with respectively rotary support plate and lower rotation supporting bracket on supporting plate, upper rotary support plate and lower rotation supporting bracket are separately installed with upper ejector pin and lower push rod, when upper ejector pin and lower push rod are respectively when being arranged on opening button on supporting plate and the same axis of switch knob, make upper ejector pin two ends corresponding with the separating brake switch on opening button and circuit breaker end plate respectively, the two ends of same lower push rod are corresponding with the closing switch on switch knob and circuit breaker end plate, therefore can operate respectively opening button and switch knob, can can distinguish separating brake switch and the closing switch on operating breaker end plate by upper ejector pin and lower push rod, can realize the urgent divide-shut brake of circuit breaker without opening cabinet door.The present invention controls respectively upper backing pin and lower backing pin by the control turn-knob being arranged on supporting plate by the upper driving lever in plate and lower driving lever, make rotary support plate and lower rotation supporting bracket respectively along its hinged center rotating to service position, therefore going up the rotation of rotary support plate makes upper ejector pin and opening button at once, its lower rotation supporting bracket can not be rotated, therefore lower push rod can be not corresponding with switch knob, even if touch one of them button by mistake, can not make corresponding push rod action yet, can thoroughly solve and touch the accident potential that divide-shut brake button causes circuit breaker misoperation by mistake, improve the fail safe of emergent switching on-off operation.The present invention is installed in upper rotary support plate, lower rotation supporting bracket, control handle, opening button and switch knob and plate on supporting plate, compact conformation, rationally, does not take space larger in cabinet, there is good versatility, be convenient to existing switchgear to improve.
