Abstract
The aim exists to reduce the size of low-tension switchgears, but on the other hand it is intended to improve the switching power. New requirements now demand that the contacts of the low-tension switchgears close more quickly in order to achieve a small amount of contact erosion and hence a longer life of the low-tension switchgears. The invention indicates a means by which a switching mechanism is produced with only a few individual parts, a bell crank system 2, 3, 4 drives a contact shaft 6 via a switching lever 1, a locking device 9, 10, 11 initially locks the contacts 7, 8 shortly before touching, and, in the case of further operation of the switching lever 1, switches on suddenly, and a trip device 14, 16, 18 opens the contacts 7, 8 in the case of a fault current. Such a switching mechanism can be used in low-tension switchgears, preferably in fault-current protection switches.
Description
The present invention relates to a kind of operation mechanism for low-tension switch of the sets of contacts that has the handle by toggle link system drive contact axle and form by dynamic and static contact.
A kind of such operating mechanism that is used for switch electrical contact control is disclosed by Deutsche Bundespatent 3508110.Its described controlling organization comprises a blocking element, and its effect is at first to be locked before switch contact contacts.This biased blocking element maintains a switch shaft of setting up transitive relation with switch contact by a disk and affacts handle up to the switching force of selecting.Along with the raising that acts on switching force on the handle, by the elastic deformation storage power between handle and the switch shaft.After overcoming switching force, the disk of biased blocking element deflection and switch shaft rolls and leaves the garden shape profile of blocking element, along with the corresponding deflection of biased blocking element, disk departs from the engagement with blocking element, switch shaft is shifted to the combined floodgate direction rapidly, produces the sudden combined floodgate of switch contact thus.This operating mechanism is parts that are arranged in traditional failure current protection switch.Other exploitation also is, makes the miniaturization of trouble power protection switch, also make thus operating mechanism than in the past occupy littler position.
Task of the present invention is to improve the operating mechanism of trouble power protection switch, and it can be placed in the little predetermined space, and has satisfied about switch power all requirements of aspect such as useful life and weatherability.
The effect that the present invention reached is, the switch operating mechanism of little overall dimension is provided, and this operating mechanism can be loaded in the different switches, is specially adapted to the trouble power protection switch, except its reliability, and also convenient the manufacturing.
The further structure of technical theme advantage of the present invention can be found out from following feature, locking device links to each other with handle (1), this locking device is made up of with long-armed (10) that link to each other with this galianconism the galianconism (9) that is connected with handle (1), this long-armed and public toggle link system (2,3,4) moving axis phase coupling, wherein adopt such setting, make that promptly locking device (9,10) was in the dead-centre position in handle (1) separating brake position, during handle (1) operation, a locking device (9,10) and the mobile by this way toggle link of spring element (a 2) system (2,3 that links to each other with handle (1), 4) common axis (5), promptly the contact axle (6) that links to each other with toggle link system (2,3,4) makes moving contact (7) non-contiguously near fixed contact (8); When handle (1) continues operation, the spring length of the spring element 2 that compression can be moved in the longitudinal direction jointly, touch the protuberance (13) of arm (9) until the protuberance (12) of handle (1), and after crossing the dead-centre position, locking device (9,10) is in extended position and removes constraint and contact 7,8 moment closure.
Its advantage is, by means of corresponding inhibition, by rotating spring to the torque that release lever produces, partly eliminated by contact and passed to power (claim 4) on the release lever by connecting rod, bar and rocking arm.Wherein, payment power size is to consider like this, so that the power partly of not offsetting still enough can overcome the frictional force of each parts and thread off reliably, therefore, the dropout active force that can act on the plate axle on the throne minimizes, and a tripping relay with quite little active force can be set.
After the tripping relay tripping operation, it must reset to initial position.This is produced effectively by a restoring board, this restoring board is arranged on the axle rotationally, and by the connecting rod end it is rotated in a clockwise direction in operating mechanism separating brake position, thus, the bar of restoring board is pressed on the contact pin of tripping relay and resets, this restoring board is made by resilient plate, therefore, this bar is leaf spring (claim 5 and 6), these leaf springs are to arrange so there, so that under the situation of the power higher than required reset force, it flexiblely is out of shape.For the balance manufacturing tolerance, the making of this restoring board can have allowance, and when operating for the first time, it adapts by the installation situation of strain with reality.To this, guarantee tripping relay fully to be resetted and can it not acted on unnecessary excessive forces.
Showed one embodiment of the present of invention in the accompanying drawing, it will be described in more detail below.
Fig. 1 has showed the operating mechanism of the trouble power protection switch that is in the separating brake position with the form of end view.
Fig. 2 has showed the operating mechanism that is in locked position of coupler with the form of end view.
Fig. 3 has showed the operating mechanism that is in closing position with the form of end view.
Fig. 4 has showed the operating mechanism that is in the separating brake position after trouble power causes dropout with the form of end view.
According to Fig. 1 to 4, the trouble power protection switch can be closed a floodgate or separating brake by handle 1.For this reason, handle 1 is connected with a toggle link system, and this toggle link system is made of spring element 2, bar 3 and connecting rod 4, and the toggle link system has a public axle 5 that is provided with movably, contact axle 6 links to each other with connecting rod 4, and this axle is loaded with and fixed contact 8 corresponding moving contacts 7.
In addition, a locking device links to each other with handle 1, and this locking device is made up of galianconism 9 and long-armed 10.Two arms are installed on common axis 11.Galianconism directly links to each other with the axis of handle 1, and long-armed 10 free end coupling is in the common axis 5 of toggle link system, and for this reason, long-armed 10 are provided with slotted hole 15 in this termination.
The operating mechanism type of action is as follows, and operating room 21 has a quick closing device that has a displacement response locking device, in separating brake position according to Fig. 1, arm 9 and 10 and axle 11 make the toggle link system be in the dead-centre position.According to the locked position of coupler of Fig. 2, will constitute the toggle link system by spring element 2, bar 3 and connecting rod 4 and be latched in a such position, in the also not contact of this position contact.When handle 1 continues operation, the stage clip of the spring element 2 that compression can be moved in the longitudinal direction jointly touches the protuberance 13 of galianconism until the protuberance 12 of handle 1, and the lever system that has arm 9 and 10 continues motion and be in extended position fast after the dead point is crossed by this system, and discharges toggle link system 2,3 and 4 quickly.Thus, contact 7,8 moment closure.
Thread off and realize by release lever 16, restoring board 18 and lock bolt 22.When tripping relay 20 actions, restoring board 18, lock bolt 22 are rotated counterclockwise, the jut 23 of lock bolt 22 discharges release lever 16 thus, this bar can be rotated counterclockwise, and can make toggle link system 2,3 and 4 to left movement by turning clockwise of rocking arm 14, contact axle 6 is in the separating brake position as shown in Figure 4.
