Abstract
The present invention relates to an operating mechanism of isolating switches in railway electric power circuits, which is a drive device for automatically turning on or turning off an isolating switch in a railway electric power transmission circuit. The operating mechanism is mainly composed of a bottom board (1), a slide board (2), crank shafts (3 and 8), a cam (4), a worm wheel (5), a worm (6), a gear (7), an upper tension spring, (9), a lower tension spring (10), a connecting rod (11), an electric magnet (12), a lock catch (13), a box body (14) and a motor (15), wherein the mechanism takes the bottom board (1) as a basal board. The slide board and a cam drive mechanism are arranged on the bottom board (1); a deceleration mechanism and a crank shaft drive mechanism are arranged under the bottom board. The mechanism utilizes the energy suddenly released by the tension springs to rapidly drive the rotating shaft (8) so as to achieve the purpose of rapidly turning on or turning off an isolating switch.
Description
The present invention is applied to automatically perform the opening and closing of disconnector in the circuit in the high voltage supply circuit of railway high voltage supply circuit and other similar railway power supply mode under the effect of control loop, belongs to the technical field of electrical equipment automation.
Railway automatically closes up, and to connect the supply terminals of circuit many for high voltage supply circuit, electric power, circuit is long, be in operation, easy et out of order during diastrous weather particularly, and cause power outage in nearly hundred kilometer range, at this moment, the maintainer must be along tens kilometers circuit, adopt the method for manually opening disconnector piecemeal to search,, maintainer's work has been brought great inconvenience because some local transit of circuit process is very inconvenient.Adopt this traditional maintenance and the method for work, not only workman's work capacity is big, and the required time is longer, generally needs several hrs or longer time to repair, in the several hrs of this reparation, because power failure, caused the work of relevant devices such as train signal to be interrupted, made that the driving order of train is upset, often a power outage will cause tens row trains late, even leading to great train operation accident, economic loss that causes and social influence are difficult to estimate.YG-5A disconnector remote control equipment (RCE) is the equipment of up-to-date use on the present railway, this equipment is designed by Nanjing water power section, but this equipment sets up channel line because of need, so investment is bigger, need again during et out of order manually to get involved remote manipulation and just can find trouble point in the supply line, therefore use also trouble.
Purpose of the present invention just provides a kind of artificial scene opening and closing one by one that do not need, but the operating mechanism for isolating switch for railway electric power supply line that carries out work by isolator operating mechanism automatically.
Operating mechanism for isolating switch for railway electric power supply line of the present invention is mainly by base plate (1), slide plate (2), bent axle (3), cam (4), worm gear (5), worm screw (6), gear (7), rotating shaft (8), last extension spring (9), tension spring (10), connecting rod (11), electromagnet (12), snap close (13) is formed, this device all is positioned at the both sides of base plate (1), and wherein being fixed on has snap close pilot pin (1-1) and a bent axle nest (3-1) on the base plate (1), and bent axle (3) passes base plate (1) and located by bent axle nest (3-1); Slide plate (2) is positioned on the base plate (1), and central channel (2-1) and open slot (2-2) are enclosed within respectively on snap close pilot pin (1-1) and the bent axle (3), on slide plate (2), be fixed with extension spring bolt (2-3) and sheave shaft (2-4), pulley (2-5) is enclosed within on the sheave shaft and can freely rotates, in addition, also be provided with on one side of slide plate can with gear (7) mating teeth bar limit (2-6), snap close (13) be positioned at the top of slide plate (2) and be hinged on snap close pilot pin (1-1) above, the other end of snap close and connecting rod (11) are hinged, connecting rod (11) has two, one end of another root is hinged on the base plate (1), the other end of two connecting rods and electromagnet (12) and pull-spring of connecting rod (11-1) are hinged, and electromagnet is fixed on the base plate (1).One end of last extension spring (9) is fixed on the extension spring bolt (2-3), and the other end is fixed on the sidewall of casing (14).Cam (4) also is positioned at the top of slide plate (2) and is fixed on the bent axle (3).Below in base plate (1) is provided with worm gear (5) worm screw (6) of power pack section and the part of cranking arm of bent axle (3), is fixed with a drive pin (5-1) on the side of worm gear (5), and worm gear (5) is enclosed within on the bent axle (3).Be provided with the minor axis (3-2) of hinged extension spring plate (10-1) usefulness on the part of cranking arm of bent axle (3), the central authorities of extension spring plate (10-1) are hinged on this minor axis, and two of tension spring (10) is separately fixed at extension spring plate (10-1) and decides on the extension spring plate (10-2).The principle of work of this device is: send drive signal by control circuit (16), pass through speed reduction gearing by motor (15), drive worm screw (6) by reducing gear (6-1) at last, drive worm gear (5) by worm screw (6), after worm gear (5) rotates, the drive pin (5-1) that is located on the worm gear rotates with worm gear (5), when drive pin (5-1) goes to cranking arm during the limit of bent axle (3), will head on cranking arm of bent axle also rotates bent axle (3) synchronously, after bent axle goes to certain angle, be that cranking arm of bent axle gone up extension spring plate (10-1) and gone to rear side, at this moment tension spring (10) is pulled to long status, in case after bent axle (3) turns over this summit, because the tension of tension spring, make the bent axle flat-out acceleration rotate, nearest until two extension spring plates.Because the unexpected rotation of bent axle, the cam (4) that is positioned at base plate (1) top also rotates rapidly thereupon, thereby propelling sheave (2-5), because pulley (2-5) is fixed on the slide plate (2) by sheave shaft (2-4), therefore, slide plate (2) also slides from a left side rapidly, the tooth bar limit that is located at slide plate one side is driven wheel (7) simultaneously also, make the rotating shaft (8) that is fixed on the gear (7) rotate rapidly, and the swing arm of disconnector just is fixed in the rotating shaft (8), so disconnector also just close rapidly.Go up simultaneously the front end that extension spring bolt (2-3) just in time moves to snap close (13), and blocked by snap close, extension spring also is elongated energy storage simultaneously on this moment, in case electric power circuit et out of order, making snap close (13) by control circuit (16) drive magnetic (12) is that rotate at the center with snap close pilot pin (1-1), makes extension spring bolt (2-3) break away from snap close (13), thereby rapidly slide plate (2) is retracted by last extension spring (9), driven wheel (7) and rotating shaft (8) are rotated, so that disconnector is opened rapidly.
The invention has the advantages that: after adopting this device, he can get rid of line fault automatically fast.General artificial debugging period is 4-5 hour, and place with a varied topography needs more than 10 hours; And adopt this device only to need a few minutes to solve, and greatly alleviated working strength of workers, improved efficiency, alleviated the handling loss that causes because of line fault, its economic benefit and social benefit are fairly obvious.
In addition, in course of action, suiting and disconnecting action of disconnector is to make the rapid action of link gear by the unexpected release of the energy of this device medi-spring, therefore meets the operation requirements of disconnector, can not produce the arcing phenomenon than making slowly because moving.Structurally, each actuating mechanism designs simply, and is reliable, not only can reduce the fault rate of machinery, but and actv. prolong service life of this device.
