As shown in the figure, the present invention includes loam cake 1, inner frame 2, pedestal 3 and be installed in loam cake and inner frame between support 4, in loam cake, be distributed with supply hub 5, luminous indication piece 6, reset button 7 and testing button 8, the below of reset button 7 and testing button 8 is respectively equipped with reset copper sheet 21 and test copper sheet 22, the both sides of pedestal are provided with inlet wire copper spare 9 and outlet copper spare 10, limit copper is set in the both sides of inner frame 2, and to plug in folder 12 relative with supply hub 5,17 one-tenth " L " shapes of coil rack, its vertical skeleton twines pull-in winding 18 outward, pull-core 19 interlock moving contact components 14 in vertical skeleton, pull-core 19 upper end roof pressure return springs 29, the horizontal skeleton of coil rack 17 twines tripping coil 20 outward, tripping coil 20 matches with iron core in the tripping mechanism, limit copper is inserted between folder 12 and the supply hub 5 emergency exit mechanism is set, emergency exit mechanism is by the base 24 of band jack 23, slip lid 25 and back-moving spring 26 constitute, slip lid 25 activities are assemblied on the base 24, between two slip lids 25 back-moving spring 26 are set; In the pedestal 3 relative, be provided with the arc-extinguishing mechanism that constitutes by striking sheet 27, arc extinguishing cover plate 28 and arc-chute 11 with dynamic and static contact, arc-chute 11 is relative with the slotted eye 38 of loam cake 1 both sides, when short circuit or overload, when dynamic and static contact forms electric arc, arc-chute 11 plays the arc extinguishing effect, and electric arc, gas, smog are discharged by the slotted eye 38 of face loam cake both sides.Fixed contact 13 on the plug in folder 12 of limit copper matches with one group of moving contact 15A on being installed in moving contact component 14, moving contact 15A and 9 conductings of inlet wire copper spare, and another group moving contact 15B matches with outlet copper spare 10, and outlet copper spare 10 is inserted with limit copper and is pressed from both sides
Isolate by insulating trip 16 between 12, about respectively organize moving contact 15, utilize four springs that are placed in moving contact component 14 grooves to carry out return, welding brush wire 43, one sides that are flexible coupling in moving contact 15 lower ends are connected with magnet ring 36.Inlet wire copper spare 9 welds with an end of short circuit tripping coil 34, the other end connects with yoke 42 welding positions, and bimetal leaf 39 is with yoke 42 welding, bimetal leaf 39 lower ends be flexible coupling brush wire 44 1 ends together, conductive copper sheet 45 welds with brush wire 44 other ends, therefore electric current imports into thus, passes on two groups of moving contacts 15.The moving contact component 14 that tripping mechanism comprises iron core, match with iron core and be arranged on the outer tripping coil 20 of iron core, iron core is connected and composed by dropout iron core 30 and impact iron core 31 movable sliding sleeves, the front end of dropout iron core 30 passes and impacts iron core 31 control moving contact components 14, the rear end roof pressure is on back-moving spring 32, back-moving spring 32 offsets with yoke 42, between impact iron core 31 and dropout iron core 30, be provided with and impact iron core return-spring 33, dropout iron core 30 is the inclined plane with the composition surface of moving contact component 14, to improve the sensitivity of threading off.Job requirement according to varying environment, the outer tripping coil of iron core is electric leakage tripping coil 20 or short circuit tripping coil 34, electric leakage tripping coil 20 links by wiring board 35 and magnet ring 36, also can be that the outer tripping coil of iron core is electric leakage tripping coil 20 and the short circuit tripping coil 34 that is set up in parallel, electric leakage tripping coil 20 links by wiring board 35 and magnet ring 36, impacts between iron core return-spring 33 and the dropout iron core 30 that insulating case 37 being set.The rear end of dropout iron core 30 can link with bimetal leaf 39, its syndeton can be that extend the rear end of dropout iron core 30 and stator 40 joins, adjustment screw 41 on the stator 40 is pressed against on the bimetal leaf 39, and the upper end of bimetal leaf 39 and yoke 42 are connected and fixed.
In working order down, when pressing reset button 7, produce pulse signal, trigger the controllable silicon conducting, make pull-in winding 18 produce immediate current, generate an electromagnetic field, make pull-core 19 and moving contact component 14 adhesive risings and 30 lockings of dropout iron core, homing action is finished in dynamic and static contact (15,13) contact.By the effect of special-purpose integrated package, not put if pin reset button 7 for a long time, coil then no current passes through, and promptly can not burn out coil, plays a protective role.
Electric leakage dropout defencive function: circuit is in closure state; when producing leakage current (residual current) in the circuit; directly by magnet ring 36 inductions; special-purpose integrated package work; and in control circuit, produce voltage signal; trigger the conducting of dropout controllable silicon; impel electric leakage tripping coil 20 charged; produce magnetic field to impact iron core 31 snap actions with moving contact component 14 no any frictions are outwards pulled out; and to the outside impulsive force of dropout iron core 30 generations; add 30 pullout forces outside under the effect of electromagnetic force of dropout iron core; both additions have improved the dropout performance greatly; dropout is swift in motion; reliably, and when low-voltage≤50V also can play the dropout defencive function.Moving contact component 14 return and thread off at official hour under the effect of return spring 29, dynamic and static contact 15,13 disconnects, and finishing the electric leakage protection action of threading off.When pressing testing button 8, just be equivalent to produce an electric leakage signal, its course of action is threaded off identical with electric leakage.
Short circuit dropout defencive function: circuit is in closure state; when circuit is short-circuited; immediate current (short circuit current) is much larger than the multiple of rated current; short circuit tripping coil 34 directly produces magnetic field; pull out dropout (pull out greater than 0.5mm and can thread off) laterally to making dropout iron core 30; moving contact component 14 is return under the effect of return spring 29, and dynamic and static contact 15,13 disconnects, and finishes short circuit dropout protection action.
Overcurrent (overload) dropout defencive function: circuit is in closure state, and having served as live stream, to surpass 1.13 times of load current value (be I
t>1.13I
n) time; by short circuit tripping coil 34 current lead-through is arrived bimetal leaf 39; bimetal leaf 39 flexural deformation laterally of will generating heat; and in official hour, dropout iron core 20 is outwards pulled out; to making moving contact component 14 return under the effect of return spring 29; overcurrent (overload) dropout protection action is finished in fixed contact 13 outages.Because bimetallic adjustment screw 41 is installed in the screw hole with the copper stator 40 of iron dropout iron core 20 welding one, can adjust the drop-away time of bimetal leaf 39 during rotation adjustment screw 41.
When reversal connection line (being power line and load line reversal connection), power supply is connected with outlet copper spare 10, (being under the trip status) control circuit is not charged before dynamic and static contact 15,13 disconnects like this, because this product adopts the electric-controlled type resetting device, circuit is not charged again, and coil can not produce magnetic field, so under the situation of reversal connection line, can not the energized operate as normal even press reset button 7, have only by correct connection to connect, could operate as normal.
