Abstract
The combined circuit-breaker with electric operation mechanism is characterized by that the isolating switch form from frame, handwheel, shaft, crank arm, pull-rod and blade and spring control mechanism controlled by auxiliary switch are mounted on the cirucit-breaker, and the interior of the isolating switch also is equipped with electric operation mechanism formed from motor, reducing mechanism, electromagnetic clutch and gear, so that said circuit-breaker is matched with the operation mechanism so as to can implement automatic coupling and mechanical linkage of vacuum arc-suppressing chamber and isolating switch,and can ensure that the coupled isolating switch is in dead operation throughout, and with remote controller remote and short-range operation can be realized, operation process is simplified and the advanced property, safety and reliability of the combined circuit-breaker are improved.
Description
The present invention relates to the motor-operating mechanism of the isolating switch that outdoor vacuum circuit breaker wears.
Isolating switch is the visible isolation fracture of vacuum circuit-breaker, and branch, the closing operation of the isolating switch of wearing as outdoor vacuum circuit breaker rely on manual operation at present and realize, the manual operation great efforts, and inconvenient operation can't realize distribution automation.
Purpose of the present invention is all providing a kind of by shaking the modular breaker with motor-operating mechanism that control realizes electric operating, simplifies the operation course, improves circuit breaker advance, fail safe, reliability.
Purpose of the present invention realizes by following technical proposal: the framework of isolating switch is connected on the breaker body, the axle that links to each other with the operation handwheel is bearing in the framework two ends, described isolating switch comprises the connecting lever that is fixed on the axle, be connected the spring between connecting lever and the framework, pull bar lower end and connecting lever are hinged, the upper end is hinged with blade, send the breaker spring operating mechanism of electricity to be connected breaker body one side by auxiliary switch control, it is characterized in that described isolating switch is provided with the motor-operating mechanism of realizing electronic divide-shut brake, this mechanism be located at and two mounting panels of frame fixation between, comprise and shake the motor of controlling electricly, motor output connects reducing gear, the reducing gear axle be provided with motor simultaneously electric adhesive is just realizing the end face engagement, the electromagnetic clutch of reverse drive and gear I, II is fixed on the axle with gear I meshed gears.
The present invention mixes automatic interlock and the mechanical interlocking that can realize breaker vacuum arc control device and isolating switch behind the motor-operating mechanism, program by the electric wiring design, make vacuum interrupter and isolating switch disconnecting link by certain standard action isolating switch that closes earlier when promptly closing a floodgate, cross 2 and move the Zhong Houzai vacuum interrupter that closes.Cut off vacuum interrupter during separating brake earlier, after 1.5 seconds, cut off isolating switch again, thereby being always, the isolating switch that has guaranteed interlock do not have the electricity operation, and can adopt the electronics remote controller to realize far, closely shaking the control operation, simplify operating process greatly, strengthened advance, fail safe and the reliability of modular breaker.
Description of drawings.
Fig. 1 faces structural representation for the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the partial top view (motor-operating mechanism structure chart) of Fig. 2.
Below in conjunction with above-mentioned accompanying drawing embodiment the present invention is remake and to specify.
Modular breaker (referring to Fig. 1-3) with motor-operating mechanism, modular breaker is meant the outdoor vacuum circuit breaker of wearing isolating switch (2), this isolating switch is the visible fracture of vacuum circuit-breaker, realize branch, feed motion by motor-operating mechanism, make easy and simple to handlely, be easy to realize distribution automation.Concrete structure is that the framework (7) of isolating switch is connected on the breaker body (1), realizes that manually operated operation handwheel (8) is connecting axle (9), and axle is bearing in the framework two ends.Isolating switch comprises and a fixing connecting lever (3) that the spring (4) that is connected between connecting lever and the framework fulcrum is to realize the energy storage that divides, closes a floodgate and release the energy spring.The lower end and the connecting lever of pull bar (5) are hinged, the upper end is hinged with blade (6), the motor-operating mechanism of realizing electronic divide-shut brake is located between two mounting panels (18) of isolating switch and frame fixation, it comprises by electric wiring shakes the motor of controlling electricly (17), motor output is after reducing gear (16) slows down, by be provided with on the reducing gear axle with motor simultaneously electromagnetic clutch (15 or 12) and the gear I (13) or the left side of electric adhesive, or right engagement realizes the transmission of power of both forward and reverse directions, electromagnetic clutch is by end face tooth and gear I engagement, and gear I had both had the special gear that the end face tooth has the cylinder tooth, it can not only mesh with the electromagnetic clutch adhesive of a left side (or right) side, also mesh simultaneously with gear II (14), gear II is fixed on the axle, with transmission of power to the axle on.
The automatic interlock course of action of isolating switch and circuit breaker is as follows:
(1) closes a floodgate: " close " or " A " button by remote controller, electromagnetic clutch in the mechanism (15) electric adhesive, motor (17) simultaneously electric rotation, driven gear and spool (9) rotation, the rotation of axle drives pull bar (5) through connecting lever (3), and pull bar pulling blade (6) is done the motion of closing a floodgate downwards.Axle makes spring (4) energy storage when beginning to rotate, treat that spring crosses that electromagnetic clutch and motor cut off the power supply simultaneously behind the point midway, electromagnetic clutch is separated with gear, and the energy continuation driving blade (6) that relies on spring to cross mid point release is done to close a floodgate and is moved, and puts in place up to the blade combined floodgate.Meanwhile auxiliary switch (11) send electricity for the time relay of spring operating mechanism (10), and time-delay 2-5 makes the breaker vacuum arc control device close a floodgate after second, finish whole feed motion.
(2) separating brake: press remote controller " branch " or D button, make breaker vacuum arc control device separating brake earlier, after treating that breaker open operation puts in place, electromagnetic clutch (12) and motor (17) electric (this moment motor turn to when closing a floodgate opposite) rotational driving gear, axle, connecting lever, pull bar etc. are done counter motion when closing a floodgate, promote blade and make separating brake and move.The reverse energy storage of spring is given in the rotation of axle simultaneously, treat that spring crosses electromagnetic clutch and motor outage behind the mid point, electromagnetic clutch separates with gear, crosses mid point by spring and releases energy and continue to drive blade and make separating brake and move, put in place up to the blade separating brake, finish whole separating brake action.Begin separation spacing from breaker vacuum arc control device separating brake to the isolating switch blade about about 1.5 seconds.
The isolating switch action is leading and the action of breaker vacuum arc control device lags behind during owing to close a floodgate, and is opposite during separating brake, so the isolating switch of interlock is always and does not have electricity and operate, guaranteed fail safe and reliability.
