As shown in Figure 2: circuit board 18 mainly is made up of shaping circuit 34, amplifying circuit 35, electric appliance circuits is connected to overload signal through current transformer the input 34-2 pin of the chip of shaping circuit 34, the chip of shaping circuit 34 is LM358, the output 34-1 pin of shaping circuit 34, after resistance, capacitance fade shaping, be connected to the input 35-1 pin of amplifying circuit 35, the output 35-16 pin of amplifying circuit 35 connects release 27, output 35-6 pin is connected to by-pass cock 14, and the chip model of this amplifying circuit 35 is FH1068.
During work, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: active copper 30, horse hook 6 are all on solid line position, input is gone into electrolytic copper 1 and is connected with the contact of moving silver point 31 by quiet silver point 32, moving silver point 31 is connected by active copper 30 and flexible conductor 19, be connected with output electric copper output 22, the work of circuit breaker device, shaping circuit 34, amplifying circuit 35 on the circuit board 18 are failure to actuate, indicating piece 33 on the indicating device 10 does not move yet, what can see on the indicating device 10 is blank, expression does not have leaky, and electric appliance circuits is normal.
In case overload fault occurs, electric appliance circuits inputs to overload signal through current transformer the input 34-2 pin of the shaping circuit 34 on the circuit board 18, shaping through shaping circuit 34, amplify, export from output 34-1 pin, through resistance, capacitance fade, shaping, input 35-1 pin to amplifying circuit 35 amplifies, shaping, export release 27 to from output 35-16 pin, release 27 is an end of pushing tow dropout link rod 26 upwards, dropout link rod 26 is rotated counterclockwise around dropout rotating shaft 25, one end of dropout link rod 26 other ends and horse hook 6 disengages, horse hook 6 has arrived dotted line position among the figure, make active copper 30 also arrive dotted line position among the figure by spring 29, this moment, moving silver point 31 disengaged with quiet silver point 32, and the circuit of going into electrolytic copper 1 and electric copper output 22 is disconnected, and electric appliance circuits just is disconnected, stop power supply, notify the maintenance personal to check, maintenance.At this moment, the 3rd end of dropout link rod 26 clockwise rotates dropout link rod 26 under the effect of extension spring 15, is returned to original position.After fixing, pulling handle 8 is to dotted line position, and horse hook 6, active copper 30 are replied original solid line position again.
In case leak current fault occurs, because under the normal conditions, flexible conductor 19 has electric current to pass through, flexible conductor 19 passes static magnet 16 again, but this undercurrent is so that static magnet 16 adhesive moving magnets 17, and when electric leakage, the electric current of flexible conductor 19 of flowing through increases greatly, cause static magnet 16 adhesive moving magnets 17, moving magnet 17 upwards, the magnetic deferrization 24 that drive is attached thereto upwards, the end that 26 contacts of magnetic deferrization 24 and dropout link rod the are connected pushing tow dropout link rod 26 that also makes progress, dropout link rod 26 rotates counterclockwise around dropout rotating shaft 25, cause the other end of dropout link rod 26 and an end of horse hook 6 to disengage, horse hook 6 has arrived dotted line position among the figure, horse hook 6 drives active copper 30 again and has also arrived dotted line position among the figure, moving silver point 31 disengages with quiet silver point 32, circuit-line is disconnected, a make progress end of pushing tow escape bar 12 of the other end of magnetic deferrization simultaneously 24, escape bar 12 is upwards oppressed stage clip 13, escape bar 12 rotates counterclockwise around escape rotating shaft 11, because the other end of escape bar 12 is stuck in the front end of indicating piece 33, along with of the rotation of this end around escape rotating shaft 11, this end leaves the origin-location, disengaging contacts with indicating piece 33 front ends, indicating piece 33 is not stuck, and to left, the release link 9 that is connected with indicating piece 33 is also to left under the effect of indication stage clip 36 for indicating piece 33, open the left side because show the perforate of indicating piece 33 on the indicating device 10 again at indicating piece 33, be blank, expression is normal, and this moment, indicating piece 33 arrived the position on the original left side, show red, leak current fault appears in expression, and should be coated with fluorescence on the redness, even dull thread also can be seen, also keep the leak current fault state after the power failure always, notify the maintenance personal in time to check, maintenance; After the outage, static magnet 16 not adhesive moving magnets 17, moving magnet 17 falls after rise downwards, and alignment pin 23 prevents that moving magnet 17 from continuing to fall and locate, and the 3rd end of extension spring 15 pulling dropout link rods 26 makes dropout link rod 26 be returned to the origin-location.After fixing, pulling handle 8 is to dotted line position, handle 8 is oppressed release link 9 to the right, release link 9 drives the also stage clip 36 of compressing indication to the right of indicating piece 33, thereby to right translation, the redness on the indicating piece 33 cannot see, can only see the blank of expression normal condition, when indicating piece 33 moved to the other end position of escape bar 12 to the right, the other end of escape bar 12 is stuck in indicating piece 33 again under the effect of stage clip 13 front end was a left end, and indicating piece 33 is fixed.Certainly, it is longer that indicating piece 33 also can be made, left side coated white, and the expression electric appliance circuits is normal, the right colored red, leak current fault appears in expression.
Rated current is the qualification of being done when all electrical equipment are all used, and to guarantee not overload operation of circuit, prevents accident.So for only using part electrical equipment; the protection meaning of rated current just is difficult to realize; therefore only with part electrical equipment the time; for guaranteeing that safety just is necessary to determine new rated current; be that rated current should be regulated; by-pass cock 14 is used for regulating rated current; the output 35-6 output of amplifying circuit 35 connects by-pass cock 14; by-pass cock 14 is one can carry out the switch that multistage is regulated; utilize the variation of resistance value to reach the control rated current; can the adjusting of three load current values in this example, as 40 peaces; 30 peaces; 20 peaces can certainly be set the adjusting of several load current values according to specific requirement.
If show other apparatus failure, can adopt a plurality of the present invention to realize.
The material of moving silver point 21, quiet silver point 23 is Agcdo, and active copper 22 materials are red coppers.
