Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
The present invention mainly is made up of high-pressure section, low-pressure section and drive part three parts:
High-pressure section comprises three-phase integrated sealing high-pressure chamber 3, and high-pressure chamber 3 is fixed on low pressure storehouse 8, is provided with arc control device 2 in the high-pressure chamber 3, and arc control device 2 are connected with down outlet 1 and last outlet 4; The outside of arc control device 2 is provided with excess of stroke adjusting device.
Low-pressure section comprises low pressure storehouse 8, and the middle part is equipped with making electromagnet 9 in low pressure storehouse 8, and making electromagnet 9 lower ends connect fixed core 10.Low pressure storehouse 8 left ends are installed with tripping electromagnet 15, and a manual separating brake bar 16 is laterally adorned at middle part, tripping electromagnet 15 back, and manual brake separating bar 16 1 ends are movably connected on 8 left side walls of low pressure storehouse, and the other end connects a dropout bent plate 17, is used for manual brake separating.Lower end, making electromagnet 9 left side is provided with altitude mixture control, is provided with the switch-on latching device with altitude mixture control homonymy upper end.
Drive part comprises drive plate 6, armature 7 and is connected bent plate 14; Be used for interlock high pressure and low-pressure section, three-phase integrated T type drive plate 6 is rotatably installed on the low pressure storehouse 8 by oscillating bearing, "-" of the drive plate 6 of T type structure is located at the rear portion in high-pressure chamber 3 and low pressure storehouse 8, " I " of T type structure is located at 8 tops, low pressure storehouse, drive plate 6 fixedly connected bent plates 14, fixedly connected armature 7 on bent plate 14 is rotationally connected by oscillating bearing 27 and low pressure storehouse 8.Position near arc control device on drive plate 6 is provided with the chute 26 that supplies arc control device guiding usefulness, and chute 26 directions are consistent with the arc control device direction.Because in deciliter when action,, slide block 22 was limited in the chute 26 of drive plate all the time, so excess of stroke adjusting device plays the effect to the arc control device guiding again.
It is exactly to change the deflection of contact spring 5 under deciliter state in fact that the excess of stroke of high-pressure chamber is regulated, rotatable swivel nut 23 is housed on arc control device moving conductive rod 21, a slide block 22 is adorned in swivel nut 23 the inners, swivel nut 23 is rotatably connected by a shaft block ring with slide block 22, drive the translation of slide block 22 by rotation swivel nut 23, thereby reach the purpose that the excess of stroke is regulated by the arc control device direction.Because in deciliter when action,, slide block 22 was limited in the chute 26 of drive plate all the time, so this device plays the effect to the arc control device guiding again.
The switch-on latching device adopts the roller type snap close, lock dog 20 is fixedlyed connected with drive plate 6 by connecting bent plate 14, one bearing 19 is installed on lock dog 20, bearing 19 rolls with locking board 18 and contacts, locking board 18 is designed to long ear shape, locking board 18 is fixedlyed connected with dropout bent plate 17, is rotatably installed on the low pressure storehouse 8 by bearing pin 24 with torsion spring, relies on torsion spring to realize resetting of locking board 18 and dropout bent plate 17.Tripping electromagnet 15 is fixedly mounted on the low pressure storehouse 8, and manual brake separating bar 16 can be automatically connected on low pressure storehouse 8 and the dropout bent plate 17.This roller bayonet type mechanism, the active force of 19 pairs of locking boards 18 of bearing points to the axis of rotation of locking board 18 all the time.Locking board 18 is designed to long ear shape as shown in the figure, can guarantee the reliability of snap close, can make the snapping amount be issued to required value in the situation that need not to adjust again, and has reduced the knot amount of taking between locking board 18 and the bearing 19.Even some deviations appear in the installation dimension of locking board 18 like this, also can directly not influence the reliability of snap close and the tripping operation under the low-voltage.Thereby realized that the snapping amount need not to adjust but the high switch-on latching device of reliability.
Altitude mixture control of the present invention is made up of rotatable spring base 11, fixed spring base 12 and sluice separating spring 13.Fixed spring base 12 is fixedly mounted on the low pressure storehouse 8, and rotatable spring base 11 carries out interlock with fixed spring base 12 by profile of tooth.When Different Altitude,, change the P2 power of sluice separating spring, adapting to the variation of the self-closing power of vacuum interrupter under the different atmospheric pressure, thereby realized adjusting with height above sea level by changing the different interlock shelves of rotatable spring base 11 and fixed spring base 12.
High-low circuit of the present invention is arranged up and down, high-pressure chamber 3 is fixed on the low pressure storehouse 8, arc control device 2 are positioned at three-phase integrated sealing high-pressure chamber 3, following outlet 1 and last outlet 4 are separately fixed on the high-pressure chamber 3, be used for being connected of contactor arc control device and outside major loop, on the high-pressure chamber 3 also specialized designs boss 25, boss 25 built-in embedding mothers are used to expand the interface of contactor-fuse combined electric apparatus.
Operation principle of the present invention is: for D type electromagnetic treadle, when making electromagnet 9 energisings, under the electromagnetic force effect, attract armature 7, armature 7 is rotated, armature 7 drives connection bent plate 14 and drive plate 6 rotates by counter clockwise direction, connect bent plate 14 compression sluice separating springs 13 and make its energy storage, simultaneously, the rotation of drive plate 6 makes arc control device moving conductive rod 21 to left movement by the P1 power of contact spring 5, the contact of arc control device dynamic/static contact is being closed a floodgate at the end, because being rotated further of drive plate 6 makes contact spring 5 produce compression, deflection is the excess of stroke, and the deformation force of this contact spring provides necessary thrust for the arc control device dynamic/static contact.Making process finishes, and the hold-in winding in the making electromagnet seals in closing circuit, and loop current reduces, and the "on" position of contactor only depends on holding current to provide.Need only during separating brake and cut off the power supply to closing circuit, electromagnet 9 loses electromagnetic force, suction to armature 7 also disappears equally, tripping spring 13 and contact spring 5 discharge the making process energy stored, promote to connect bent plate 14 and the rotation of drive plate 6 clockwise directions, drive arc control device moving conductive rod 21 by slide block 22, swivel nut 23 and chute 26 and move right, realized the separating brake process of contactor.
For J type mechanical contactor, it closes, the separating brake process is with D type contactor, and different is that J type contactor is to realize by mechanical lock buckle after combined floodgate puts in place, i.e. the locking of 18 pairs of bearings 19 of locking board.During separating brake, as long as to tripping electromagnet 15 energisings, its moving iron core moves upward, and dropout bent plate 17 and locking board 18 are turned clockwise around pivot pin 24, removes the lock-out state of 18 pairs of bearings 19 of locking board, realizes the separating brake of contactor.J type contactor also has manual brake separating bar 16, and when manual brake separating, manual brake separating bar 16 moves right, and by block card on it and packing ring snap close bent plate 17 and locking board 18 is turned clockwise around pivot pin 24.Remove the lock-out state of 18 pairs of bearings 19 of locking board.
