Below in conjunction with accompanying drawing and embodiment electronic electromagnetic intelligent switch of the present invention is described in detail:
Fig. 1 is the mounting structure sketch map of electronic electromagnetic intelligent switch of the present invention, and arc extinguisher I is fixedly mounted on the base of fixed contact 2 in Fig. 1.Closed mutually with fixed contact 2 during moving contact 4 energisings, fixed contact 2 is connected with power supply through mains side lead-in wire 5.On mains side lead-in wire 5, idiostatic current transformer 6 and electric arc postwave electronic arc-suppressor II are housed, this electric arc postwave electronic arc-suppressor II and application number are that disclosed electric arc ripple back edge electronic arc-suppressor II is a same structure in 200920033154.5 the invention application.
By Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6; The top of arc extinguisher I is provided with top cover 29; Inner fixed contact 2 is connected with striking contact 3 on the striking contact assembly 17 through connecting line 45; Striking contact assembly 17 is that triangle, both sides are that two kinds of basic configurations of rectangle and the ceramic grid sheet 18 that has two through holes and the both sides bar shaped striking contact 3 that has through hole are formed by the centre, and other are in order to adapt to the installation site needs, and are slightly different like its shape of turning; Be fixed into top and anterior striking contact assembly with the curved bolt 22 of band again; Anterior last the striking contact of assembly is longer, has two holes, four through hole outsides and is connected with straight insulated bolt 23 and longer contact 3 of bottom and grid sheet 18, connects into a striking group assembly 17 of an integral body at last.Handling ease particularly overcome the problem that big assembly can't be processed in the prior art, and rate of finished products is high like this.
Connect lead 45 on each contact of striking contact 3; Each lead 45 is connected with the coil that some numbers of turn do not wait; The coil that said some numbers of turn do not wait is interconnected into a whole coil 44 again, arc extinguishing grid pieces 18 and striking contact 3 alternately, be arranged in above the coil outside, the front and below.Be the full big advantage of magnetic flow of performance soft magnet core, iron core 46 adopts soft magnet core.Soft magnet core 46 passes coil 44; Its outside extends to the soft magnetism zone of the both sides, bottom of the are-tight grid chip module of insulation; This zone is in order to guarantee that electric arc does not receive the influence of square magnetic core 21 remanent magnetism; So that arc energy reliably gets into the soft magnetism zone of arc control device; This soft magnetism zone is exactly the zone that can produce at any time with the synchronous basically magnetic force of electric current; Insulate are-tight grid sheet 68 tops and ionic absorption grid sheet 69 both sides are provided with square magnetic core zone again, two zones respectively account for area what can according to the characteristic of used ferromagnetic material and and arc control device current limiting capacity and zero passage arc quenching characteristic suitably regulated, the square magnetic core also can dispose the iron core of different performance as required at diverse location.The size of square magnetic area and variation of magnetic force will guarantee that the magnetic force when little electric current can be removed square magnetic core 21 remanent magnetism, make the smooth arc extinguishing of arc current this moment.Soft magnet core 46 is connected the mode that adopts butt joint and soft magnet core 46 to overlap outside square magnetic core 21 with square magnetic core 21 junctions also fastening with countersunk head screw 27; Coil magnetic force reaches the square magnetic area around just reaching through soft magnet core 46 like this, and warp butt joint and lap-joint carry out degaussing to square magnetic core 21 and magnetize again.Ionic absorption grid sheet 69 is equipped with accelerating insulation recovery in are-tight grid sheet 68 tops of insulating, or the are-tight grid 25 of thin insulating are to add the long arc route.After electric arc got into the square magnetic area, if current magnetic force is identical with last time magnetic force direction, then current magnetic force continued to promote the preceding and then arc extinguishing of electric arc with magnetic force addition last time; If this time magnetic force is with last time opposite,, and make square magnetic core 21 be replaced by the magnetic force identical with this magnetic force direction just then this magnetic force is constantly removed the last time remanent magnetism of square magnetic core 21; Under the acting in conjunction of soft magnetism and square magnetic core magnetic force, electric arc is constantly pushed grid sheet upper end to, and is fixed up then;, arc current remains unchanged basically when descending, so arc ions is still produced bigger collision, power such as extruding owing to square magnetic core magnetic force remanent magnetism; Arc motion is formed big resistance; Form zero so that electric arc shifts to an earlier date stop motion, voltage height that electric arc is pressed down and coil ampere-turn and core area are magnetic field intensity, and be relevant with the product of arc path length, shape; It's the zero-sum medium recovery time is past the electric arc that so just extended, thereby reaches arc extinguishing.
The rear portion of arc extinguisher I is provided with electric arc zero passage arc-control device 28; This electric arc zero passage arc-control device 28 is to be combined alternately by diamagnetic sheet metal that has the oblique angle and rectangular diamagnetic sheet metal, and adjacent two rightabout settings that have the diamagnetic sheet metal at oblique angle by the oblique angle.This device be rely on magnetic force through guidance contacts 30 with electric arc under be pushed into top, and push grid sheet rightabout end to arc extinguishing.Below zero passage arc-control device 28, be connected with protective tube 70 through connecting line.
Fig. 6 is the structural representation of fixed contact assembly, and Fig. 7 is the left side view of Fig. 6; By Fig. 6 and Fig. 7, bending part blocks in the copper sheet upper and lower of fixed contact 2, and welding one connecting lever 7 is connected with following fixed head 11 on copper sheet; Iron core 12 is housed in the connecting lever 7; The top is stretched in iron core 12 both sides, increases magnetic force during little electric current, and core sataration makes thrust unlikely excessive during big electric current; Fixed support 13 is equipped with in iron core 12 bottoms, when the major break down electric current is arranged, can bear big electric power.After switch closes a floodgate; Keep a narrow slot between connecting lever 7 and moving contact 4 conducting rods, the effect of connecting lever 7 is when circuit has fault, produces very high thrust between connecting lever 7 and moving contact 4 conducting rods; Make switch directly act on tripping operation without the electric loop of relaying protection and switching mechanism; Accelerate tripping operation speed, realized the intelligent function of switch, improved the reliability of switch.Be welded with flexible steel disc 8 at the back at copper sheet, steel disc 8 makes to have more narrow slit, the degaussing in order to avoid produce eddy current, and the also available steel wire of steel disc 8 adds the insulation combination and replaces.Adding insulation after steel disc 8 bendings is fixed on the fixed head 11; Steel disc 8 also quite increases an about turn coil, in order to satisfy the conductive section requirement not only as magnetic conductor but also as resiliency supported; 11 of connecting lever 7 and fixed heads also connect an annealed copper wire 9, and fixed contact 2 is connected with coil 44 through connecting lead 45.When being used for the less situation of fault current, fixed contact 2 copper sheets also can be provided with iron core at the back.Fixed contact 2 upper ends are fixed with arc ignition bar 19; Electric arc is pushed into arc ignition bar 19 terminal also accesses than multiple contact and coil rapidly under magneticaction when the switch disconnection has electric current; Then under the coil magneticaction; Electric arc is pushed coil upper end and front end more rapidly to, and constantly inserts more multi-thread circle and strengthen magnetic force through each striking contact, simultaneously electric arc is pushed in arc control device 1 top and the anterior grid sheet.
By Fig. 8, Fig. 9 and Figure 10, it is that the protrusion slanted bar 24 of 24, two kinds of shapes of protrusion slanted bar of two kinds of shapes of concave, convex is spaced that the lower surface of the are-tight grid sheet 68 that insulate is provided with the center, protrusion slanted bar 24 and its front at are-tight grid sheet 68 back sides of the insulating layout that misplaces mutually.So that arc column disperseed the path tortuous when electric arc was pushed by magnetic force, increase resistance, the are-tight grid 25 of several thin insulatings are equipped with to add long arc route or ionic absorption grid sheet 69 to accelerate the removing of arc ions in top; In addition, the protrusion slanted bar 24 on the are-tight grid sheet 68 that insulate from last to under shape can also be set to from high to low, the insulation of this kind shape is are-tight can only install ionic absorption grid sheet 69 between the grid sheet 68.Electric arc postwave electronic arc-suppressor II and airtight arc control device IV are housed between several ionic absorption grid sheets 69.
Figure 11, Figure 12 and Figure 13 are used for more than the 35Kv the more mounting structure sketch map of high-voltage switch; When being used for more high voltage double break mouth switch; A fracture is installed arc extinguisher I; A fracture is installed sulphur hexafluoride arc control device 115 or vacuum interrupter, in the middle of these two fractures insulation column 117 is set, and the set inside rotation axis 121 of insulation column 117 also is connected to operating mechanism with the console switch folding; Insulation column 117 tops are provided with movable contact rod 118; One end of movable contact rod 118 is moving contact 4 and insulation connecting plate 122 fixedly; And through the insulation connecting plate 122 be connected with moving contact 4, the other end is connected with the moving contact 123 that can in the sliding tray on the movable contact rod 118 124, slide through soft line 120; Sulphur hexafluoride arc control device 115 set inside guide rings 127 and lobe shape contact 119, the purpose that guide ring 127 is set is to make moving contact 123 can successfully enter in the lobe shape contact 119.Outer setting retainer plate 126.
Arc extinguisher I and sulphur hexafluoride arc control device 115 usefulness double insulators 116 are supported fixing; Sequence of movement is, switch closes, the contact of arc extinguisher I closes first branch after being when tripping, and the contact of sulphur hexafluoride arc control device 115 is to close afterwards earlier to divide; When switch closes a floodgate like this such as circuit when fault is arranged; Do not have electric arc to produce during sulphur hexafluoride arc control device 115 contact closure, when the arc extinguisher I contact closure, arrive just discharge generation electric arc of certain distance, producing very between contact, high thrust can not be closed a floodgate switch; Electronic intelligence detects judgment means and moves simultaneously mechanism is returned when for high-voltage switch more; And carry out the arc extinguishing process simultaneously, and then sulphur hexafluoride arc control device 115 side contacts break off, and at this moment electric arc is because of arrived arc reduction less by arc extinguisher I; Sulphur hexafluoride arc control device 115 just break off zero passage electric arc; Alleviated the contact burden of sulphur hexafluoride arc control device 115, brought into play the strong and strong advantage separately of the fast zero passage arc extinguishing of sulphur hexafluoride medium recovery ability of electromagnetism limit arc ability, so at this moment sulphur hexafluoride arc control device 115 contacts can adopt lobe type contact 119.Still there is fault like switch circuit when the reclosing; Then process situation when closing a floodgate is identical, has accelerated the tripping operation process like this and has avoided the impact to system, passes through the course of action of protection switch mechanism after also having avoided closing as present switch again; Prolonged the time; Increase the probability of protection mechanism tripping, when circuit did not have fault, then switch closed a floodgate smoothly.Perhaps two arc control device are all used the electromagnetic blow-chamber, limit the arc better effects if like this, and Installation and Debugging are simpler.
Figure 14 is an electronic intelligence checkout gear circuit diagram, and when circuit breaks down electric current when big, 6 sending and receiving light pipes 100 of idiostatic current transformer just have big light signal output; Light signal is delivered to photosensitive tube 102 photosensitive tube conductings through optical fiber 101 and through potentiometer 104, capacitor 105 promptly triggers monostable clocked flip-flop 106 in order to prevent to disturb usefulness after potentiometer reaches set point; Triode 108 makes triode 108 collector potential step-downs through resistance 109 immediately; Triode 110 ends, and makes contacting controling circuit 111 outage, shutdown switch feed motions immediately; Avoid switch to be combined on the faulty line, cause bigger loss.
Below the arc quenching principle of electronic electromagnetic intelligent switch of the present invention and process are done further to detail:
When switch closure, moving contact 4 closely contacts with fixed contact 2, makes circuit connect normal operation; Arc extinguisher I is in idle condition, and moving contact 4 breaks away from fixed contact 2 earlier when switch breaks off, and under the effect of magnetic force, passes through arc ignition bar 19 then; Electric arc is pushed the terminal striking contact 3 of striking contact assembly 17 rapidly to, gets into simultaneously in the are-tight grid sheet 68 of insulation, and electric arc is under the collision of arc-chute, extruding, elongation effect; Reduce significantly rapidly, when arc current descends,, make arc reduction under same extruding, the collision at magnetic force because square magnetic core 21 still has very strong magnetic force; And electric arc gets into removing in the zero passage arc-control device 28 by ionic absorption grid sheet 69 and through leading arc bar 30 under square magnetic core 21 magneticactions, so that become zero in advance, has prolonged zero passage and medium recovery time; As can not extinguish; Electric arc gets in the ionic absorption grid sheet 69 more then, because of being connected with electric arc postwave electronic arc-suppressor II or airtight arc control device IV on the grid sheet, because the triode 58 of electric arc postwave electronic arc-suppressor II or thyristor 60 wiring are in the opposite direction paired; So no matter the sense of current how; Capital short circuit grid sheet perhaps gets into airtight arc control device IV and makes the grid sheet short circuit in the cross-over connection, arc extinction.When arc control device have fault can not arc extinguishing the time, electric arc gets in the automatically replaceable protective tube 70 of back and arc extinguishing again.When bigger fault current takes place in circuit; Just produce very high thrust between switch fixed contact connecting lever 7 and moving contact conducting rod; A kind of intelligent operating mechanism for high voltage electric switch that cooperates applicant's development, switch just can directly trip without the process of relaying protection and switching mechanism electric loop complicacy, have accelerated switch trip speed; Realize intelligent function, improved the reliability of switch.
