The utlity model has reverse wiring protection function in order to make; when installation personnel wiring error; stop power supply input live wire, zero line to be electrically connected with power supply output live wire, zero line; as shown in Figure 3, Figure 4, a horizontal carriage release lever 60 that stops reverse wiring and one can drive the helical winding 62 that carriage release lever 60 moves to the utility model on the next door of release assembly 38.One end 61 of carriage release lever 60 is positioned at bullet 49 following of the metal guiding lock 48 that passes the slotted eye 41 on release assembly 38 center through hole 39, the snap close 40 and (as shown in Figure 7).The other end 71 of carriage release lever 60 is between the K switch contact 69,70 of helical winding 62 1 sides, and simultaneously, carriage release lever 60 is fixed on the iron core 63 of helical winding 62.Be placed with a permanent-magnet electromagnet 68 in the hole of helical winding 62 afterbodys, on the iron core 63 at helical winding 62 centers that link to each other with carriage release lever 60, be with spring 66.
The helical winding 62 that drive carriage release lever 60 moves is provided with two wiring pins 64,65, pin 64,65 is welded on respectively on the wiring board 36, pin 64 is connected on the negative electricity of diode rectifier bridge D1-D4 on the wiring board 36, and pin 65 is connected on power supply input live wire (HOT) by switch plate K and goes up (as Fig. 8).
When the wiring of the utility model power input is correct, import power supply and be connected on input (LINE) when going up, there is electric current to flow through in the helical winding 62, produce magnetic field, carriage release lever 60 is subjected to the attraction of the permanent magnet 68 of helical winding 62 afterbodys, direction to permanent magnet 68 moves, 71 of carriage release lever 60 1 ends have disconnected the switch plate K that is connected between helical winding 62 and the input live wire (HOT), carriage release lever 60 and the iron core 63 that links to each other with carriage release lever 60 are held for a long time by permanent magnet 68, the other end 61 of carriage release lever 60 gets out of the way guiding lock 48, guiding lock 48 can be moved up and down in the center through hole 39 of trip assembley therefor 38, thereby power input is electrically connected with output.
When the utility model power input wiring error reverse wiring, import power supply and be connected on output (LOAD) when going up, no current flows through in the coil 62, carriage release lever 60 does not move and is in the prevention reset mode all the time, guiding lock 48 can not move up and down in the center through hole 39 of trip assembley therefor 38, thereby stops the electrical connection of power input and output.
The utlity model has the principle of creepage protection function and reverse wiring protection function below in conjunction with Fig. 5～Fig. 8 explanation.
The schematic diagram that the input and output power connected when Fig. 5 correctly installed wiring for the utility model.With reference to figure 5 and shown in Figure 8, when installation personnel will be imported live wire (HOT) that power supply is connected on the utility model input side (LINE) and zero line (WHITE) and go up, there is electric current to flow through in the helical winding 62, produce magnetic field, carriage release lever 60 is subjected to the attraction of the permanent magnet 68 of helical winding 62 afterbodys, direction to permanent magnet 68 moves, and makes carriage release lever 60 move to position 67 rapidly.Simultaneously, an end 67 of carriage release lever 60 disconnects the switch plate K of helical winding 62, and no current flows through in the coil 62, and carriage release lever 60 is subjected to the suction of iron core 63 and permanent magnet 68 to remain on 67 places, position for a long time.At this moment, depress reset button 9, the conical head 49 of the metal that is attached thereto guiding lock 48 slides in the elliptical aperture 41 of " L " shape snap close 40 of the spring 46 of being threaded off, dropout iron core 42 roof pressures; Discharge reset button (RESET) 9, reset button (RESET) 9 is subjected to the effect of back-moving spring 50 upward pressures, and metal guiding lock 48 moves up; Because guiding lock 48 moves up, drive release assembly 38 also moves up thereupon, again because live wire, zero line input contact arm 34,35 are positioned at release assembly 38 both sides side arms 381,382 top, along with release assembly 38 moves up, live wire, zero line input contact arm 34,35 also move up thereupon, live wire like this, zero line input contact arm 34, a pair of input moving contact 26 on 35,27 just respectively with live wire, zero line output conductor 14, a pair of electrical contact 24 on 15,25 are connected, thereby realized under the correct wiring state that the input power supply is connected with the electric power of out-put supply.
When wanting to cut off the electric power output of socket, as Fig. 6, shown in Figure 8, press experiment button (TEST) 8, sheet 28, experiment resistance link to each other generation short circuit current (leakage current) with zero-power line by experiment to make live wire output conductor 14.After differential differentiating transformer 33 detects this leakage current, make the controllable silicon SCR triggering and conducting, tripping coil (SOL) 45 has produced magnetic field, makes dropout iron core 42 drive snap close 40 rapidly and moves right; The conical head that making guiding lock 48 upwards flees from out in the elliptical aperture 41 from the snap close 40 rapidly; At this moment, release assembly 38 moves down, and drive live wire, zero line input contact arm 34,35 move down, and makes power supply import moving contact 26,27 and 24,25 disconnections of power supply output electrical contact, thus the purpose of realization input, output power disconnection.
In like manner, when the utility model in use, when short circuit or leaky occurring, as Fig. 6, shown in Figure 8.After differential differentiating transformer 33 detects this leakage current or short circuit current, just make the controllable silicon SCR triggering and conducting, tripping coil (SOL) 45 has produced magnetic field, makes dropout iron core 42 drive snap close 40 rapidly and moves right; The conical head that making guiding lock 48 upwards flees from out in the elliptical aperture 41 from the snap close 40 rapidly; Because the conical head of guiding lock 48 upwards flees from out in the elliptical aperture 41 of snap close 40; release assembly 38 moves down; drive live wire, zero line input contact arm 34,35 move down; power supply input moving contact 26,27 and power supply output electrical contact 24,25 are disconnected; thereby realize that input, output power disconnect, and play the purpose of protection.
Fig. 7 stops and imports the schematic diagram that power supply is connected with out-put supply electric power for the utlity model has reverse wiring protection function.As Fig. 7, shown in Figure 8, when installation personnel is installed, mistakenly power input line is received on the output of earth leakage protective socket (LOAD), and when the input (LINE) that power supply output line is received earth leakage protective socket gone up, owing to stop the two pins 64 of the helical winding 62 of reverse wiring, the 65th, be connected on the HOT of input side (LINE) respectively, on the diode rectifier bridge negative terminal, if mistakenly a pair of power input line is connected on the HOT and WHITE line of outlet side (LOAD) when installing, because input moving contact 26,27 with output electric contact 24,25 are in off-state, helical winding 62 no adhesive power supplys, helical winding 62 does not produce magnetic field, and carriage release lever 60 just rests on 68 places, position all the time; At this moment; even firmly depress reset button (RESET) 9; the conical head of guiding lock 48 withstands on the end 61 of carriage release lever 60 all the time; guiding lock 48 can not be moved in release assembly 38; can not drive live wire, zero line input contact arm 34,35 moves up; power supply input moving contact 26,27 can not be connected by electric power all the time with power supply output electrical contact 24,25; realized reverse wiring protection function from face, promptly when installation personnel wiring error, stoped the input power supply to be connected with the electric power of out-put supply.
The above only is preferred embodiment of the present utility model, and protection range of the present utility model is not limited thereto.Anyly all belong within the utility model protection range based on the equivalent transformation on the technical solutions of the utility model.
