In one embodiment, the electrical leakage tripping device 40 of earth leakage protective device 8 has three states: gate-dividing state, "on" position and trip status.Fig. 7, Fig. 8 a-8c, Fig. 9 a-9c and Figure 10 have disclosed the state that electrical leakage tripping device is in the earth leakage protective device under gate-dividing state, "on" position and the trip status respectively.Wherein Fig. 7 has disclosed the front view of the earth leakage protective device of the circuit breaker that distributes according to the optimization space of one embodiment of the invention, and wherein electrical leakage tripping device is in "on" position.Electrical leakage tripping device is in the separating brake position among Fig. 8 a, Fig. 8 b and Fig. 8 c, and Fig. 8 b is the dorsal view of Fig. 8 a, and Fig. 8 c is the end view of Fig. 8 b.Electrical leakage tripping device is in closing position among Fig. 9 a, Fig. 9 b and Fig. 9 c, and Fig. 9 b is the dorsal view of Fig. 9 a.Electrical leakage tripping device is in trip status among Figure 10.
More specifically, Fig. 8 b is the left view of Fig. 8 a, and Fig. 8 c is the rearview of Fig. 8 a.As shown in the figure, electrical leakage tripping device 40 comprises handle 50, U type bar 51, snap close 52, connecting rod 54, tripping 56, release link 61, release lever 59 and elastic spring 60.Handle 50 in the electrical leakage tripping device 40 can be used as the electric leakage indication; Rotating first 74 place that is fixed on the 3rd shell 3; The spring 49 of handle 50 is positioned on the handle 50, and spring 49 has two arms, and an arm acts on the handle 50; One arm acts on the shell 3, plays the effect that handle 50 is resetted.One end of U type bar 51 is positioned in first hole 71 in the handle 50, and the other end is positioned in second hole 72 of snap close 52.Another hole on the snap close 52, the 3rd hole 73 are rotatably mounted in the axle on the connecting rod 54.The hole 533 of connecting rod 54 is rotatably mounted to the 7th 88 places on the shell 3.Tripping 56 overlays on the connecting rod 54, and can be on connecting rod 54 second 78 be rotated.Release link 61 is rotatably mounted on the 3rd 84 of shell 3, and elastic spring 60 is fixed on root 46 positions of release link 61, and release lever 59 is rotatably mounted to the 4th 85 of shell 3.Torsion spring 70 is fixed on the 7th 88, and the one of which arm acts on the shell 3, and another arm acts on the 8th 89 of connecting rod 54, and connecting rod 54 is produced a clockwise power.Magnetictrip 63 is fixed on the 5th 86 and the 6th 87 on the shell 3.In Fig. 8 c, can more clearly see the allocation of space situation between the parts such as snap close 52, connecting rod 54, tripping 56, release link 61, release lever 59.On Width, connecting rod 54 and release link 61 coplanes, tripping 56 and release lever 59 coplanes, 83 places, bottom of elastic spring 60 are bigger than other position areas of reed, to such an extent as on Width, can contact with release lever 59.
When gate-dividing state, shown in Fig. 8 a-8c, can see snap close 52 and two dropout faces of tripping 56 this moment, the first dropout face 75 and the second dropout face 76 are in separated position.When closing a floodgate; The taper knob drive handle 50 of circuit breaker overcomes spring 49 and rotates counterclockwise; Handle 50 makes snap close 52 and tripping 56 at the first dropout face 75 and the second dropout face, 76 place's snap closes through U type bar 51; Thereby the huge torsion that comes connecting rod 54 to overcome torsion spring 70 rotates counterclockwise, and the lance 81 of connecting rod 54 bottoms hits the top 80 of release link 61, drives release link 61 and elastic spring 60 and clockwise rotates; Make the push rod 79 on the magnetictrip 63 pushed back initial position, accomplish resetting of magnetictrip 63; Simultaneously, an arm 90 of tripping 56 drives an arm 91 of release levers 59, release lever 59 is rotated counterclockwise and resets.
After accomplishing above-mentioned action, electrical leakage tripping device 40 is in closing position, sees Fig. 9 a-9c.
When instrument transformer 62 detected leakage current, instrument transformer 62 sent actuating signal to magnetictrip 63, and the push rod 79 on the magnetictrip 63 is ejected; Thereby hit elastic spring 60 lower ends 83, hitting power is passed to the bossing 41 on the release lever 59 that contacts with it by reed 60, release lever 59 is turned clockwise; The lower end 90 of tripping 56 is hit in the upper end 91 of release lever 59; After tripping 56 received counterclockwise power, the first dropout face (top dropout face) 75 separated with the second dropout face 76 of snap close 52 immediately, and electrical leakage tripping device 40 is accomplished and threaded off; When electrical leakage tripping device 40 is threaded off; The bending part 82 of connecting rod 54 can hit the 9th 65, the nine 65 and link to each other with the first overcurrent protection utmost point and first operating mechanism of the second overcurrent protection utmost point and the release lever of second operation machine structure of circuit breaker, thereby makes circuit breaker tripping.
Among Fig. 9 a-9c because the push rod 79 on the magnetictrip 63 ejects is instantaneous; The U type bar 51 that links to each other with handle in moment has little time action; Therefore the snap close 52 that links to each other with U type bar 51 all is in temporary transient inactive state, and tripping 56 receives the impulse force of release lever 59 and rotate counterclockwise.
Among Fig. 3 a 38 expression testing button 55 is positioned at upper surface 101 and 108 places, side.Torsion spring 57 is fixed on the axle 58 on the shell 3, and one of which arm 68 passes shell 3 and links to each other on electric with second terminals (end of incoming cables) 26 of the second overcurrent protection utmost point 7.Test resistance 19 is fixed on (see figure 5) in the first overcurrent protection utmost point 6; One pin of test resistance 19 passes shell 2, fixing (see figure 7) on half pass groove 66 between the middle and upper part of shell 3, zone 28 (the first short circuit wink move protective device 28) and the handle 50 (leak electricity and indicate handle).Another pin of test resistance 19 links to each other on electric with the coil 46 that moves in the protective device 28 in the first short circuit wink of the first overcurrent protection utmost point 6; Coil 46 passes (similar of moving protective device 34 and coil 47 and flexible cord 45 the second short circuit wink) through flexible cord 44 from instrument transformer 62, spot-welded together with first terminals (leading-out terminal) 24 of the first overcurrent protection utmost point 6.Another arm 67 of torsion spring 57 forms a fracture with a pin of test resistance 19 in 69 positions.
When testing button 55 was pressed, the compression leg of testing button bottom was pressed an arm 67 of torsion spring 57, contacted with the pin of test resistance 19 in being placed on half pass groove 66; Make test loop 22 conductings; Form the test leakage current, thereby make electrical leakage tripping device thread off 40, circuit breaker breaks off.
Electrical leakage tripping device is in trip status among Figure 10.That describes among wherein each parts and Fig. 8 a-8c and Fig. 9 a-9c is similar, no longer repeat specification here.
The circuit breaker that optimization space of the present invention is distributed is incorporated in the same circuit breaker product two-stage overcurrent protection utmost point and leakage protection module through reasonably optimizing and arrangement space to the circuit breaker inner space, reaches the effect that reduces spatial volume.
