In addition; In the reset lock mechanism; The reset locking hole 401 of matching with electromagnetic trip iron core 151 on the reset key 4 is not unique structure; Also can be to be employed in the mode that release link 14 relevant positions are provided with the outstanding barb 403 that resets, the barb 403 that resets can be to make through the mode of punching, and be shown in figure 17.
The operation principle of this socket type earth-fault line-breaker is following: the circuit theory diagrams of this socket type earth-fault line-breaker are shown in accompanying drawing 25; The socket type earth-fault line-breaker is under initial condition; Reset key 4 under the elastic force effect of key back-moving spring 17 in a state of nature; At this moment, the slide block 22 that resets glides under the effect of slide block 22 resetting devices (promptly the compressing spring 24) that reset and breaks away from reset cradle 12, makes the outstanding inclined-plane 142 on the slide block 22 that resets fail to act on mutually with the inclined-plane 121 that resets; Electromagnetic trip iron core 151 is under the elastic force effect of iron core return-spring 153; The interlock hole 143 that front end passes the slide block 22 that resets is against the below in reset locking hole 401, and reset cradle 12 slides to the second place under the elastic force effect of support back-moving spring 13, and the contact is in trip status (being off-state); When manually pushing reset key 4 when resetting; At this moment; The elastic force that pressure overcomes key back-moving spring 17 moves down reset key 4, and meanwhile, the front end of electromagnetic trip iron core 151 makes electromagnetic trip iron core 151 retreat under the effect on inclined-plane; And slip in the reset locking hole 401; After removing external force, move on together with release link 14, because the front end of electromagnetic trip iron core 151 is that the interlock hole 143 of passing the slide block 22 that resets is inserted in the reset locking hole 401, therefore in reset key 4 under the elastic force effect of key back-moving spring 17; The slide block 22 that resets form interlock with release link 14 and on move; On this, move past in the journey, the outstanding inclined-plane 142 on the slide block 22 that resets acts on the inclined-plane 121 that resets mutually, overcomes the elastic force of support back-moving spring 13; Promote reset cradle 12 and slide to primary importance and power supply input conduction fixed contact 701,702 is contacted with the conduction moving contact 801 (K1 in the accompanying drawing 25) of short circuit conducting strip 8 and be in reset mode (being on-state), while reed switch 18 (S2 in the accompanying drawing 25) breaks off under the ejection of release link 14 ends; When having detected leakage current; Leakaging signal detecting circuit makes 15 actions of electromagnetic trip mechanism, and promptly electromagnetic trip iron core 151 bounces back under the effect of electromagnetic force, and the end breaks away from reset locking hole 401; Release link 14 is moved under the elastic force effect of key back-moving spring 17 together with reset key 4; The slide block 22 that resets glides under the effect of slide block 22 resetting devices (promptly the compressing spring 24) that reset and breaks away from reset cradle 12 in a state of nature, and reset cradle 12 slides to the second place under the elastic force effect of support back-moving spring 13 simultaneously, and the contact is in trip status (being off-state); Socket output precision 10 and 9 outages of wiring output precision reach earth leakage protective purpose.
Under trip status; When circuit occurring and connect anti-situation; Owing to reed switch 18 (being S2 in the accompanying drawing 25) closing of contact this moment, electromagnetic generator 161 (T4 in the accompanying drawing 25) power branch that is connected on the wiring output precision 9 obtains power supply, controls said Electromagnetically actuated support 162 actions and makes said electric conduction electrode-plate 164,165 moving contacts (K2 in the accompanying drawing 25) and 105,106 disconnections of socket output fixed contact; Cut off the power supply on the socket output precision; Make non-transformer output in the socket aperture, play and remind and the reverse wiring protective effect, eliminated potential safety hazard; One side reed of simultaneously Electromagnetically actuated support 162 touching maintained switchs 23 (S3 in the accompanying drawing 25) is drawn close to the opposite side reed; Make maintained switch 23 (S3 in the accompanying drawing 25) closure, when external force continues reset key 4 to press, also because maintained switch 23 (S3 in the accompanying drawing 25) is still closed; Electromagnetic generator 161 (T4 in the accompanying drawing 25) power branch that is connected on the wiring output precision 9 still can obtain power supply; Control said Electromagnetically actuated support 162 actions said electric conduction electrode-plate 164,165 moving contacts (K2 in the accompanying drawing 25) and socket output fixed contact 105,106 are broken off, still non-transformer output still can be played and remind and the reverse wiring protective effect on the socket output precision.
