A balance adjustment rack 308, be socketed in soft magnetic bodies 312 (referring to Fig. 3 a) on, the two ends of this balance adjustment rack 308 are provided with storage tank respectively, place in it and adjust piece 309, when balancing stand 308 with soft magnetic bodies on the moving moving contact 305 of shipper pole when contacting with fixed contact 203, this adjusts piece 309 under the downforce effect of a fixed contact (for example right-hand member fixed contact 203 of Fig. 3 c) to a moving contact, adjusts the contact force of another moving contact and another fixed contact (for example left end fixed contact 203 of Fig. 3 c).
Wherein, the bottom of described adjustment piece 306 is provided with the central pivot point of a projection;
Wherein, the storage tank of described balance adjustment rack 308 has a depression that adapts with the central pivot point of adjusting piece.
Wherein, the size of described adjustment piece is enough to make it to swing in storage tank.
Wherein, when 310 short time of closing coil switch on, draw magnetic force on producing one, make on the soft magnetic bodies and move,, make soft magnetic bodies 312 drive moving contacts 305 thus and contact with fixed contact 203 with the permanent magnet adhesive; When 311 short time of broken coil switch on, produce a drop-down magnetic force, soft magnetic bodies 312 is moved down, separate with permanent magnet 202, make soft magnetic bodies 312 drive moving contact 305 thus and disengage with fixed contact 203.
Wherein, be provided with a retainer spring 307 in the described sleeve, the fixedly connected sleeve of one end, the fixedly connected soft magnetic bodies 312 of its other end.When broken coil 311 energisings, can utilize the recovery elastic force of broken coil 311 and retainer spring 307 like this, make soft magnetic bodies 307 break away from permanent magnet 202.
Wherein, described soft magnetic bodies 312 forms one with balancing stand 308.
Wherein, the both sides of described balancing stand 308 are respectively equipped with the balance of insulation and adjust piece 309, and described soft magnetic bodies 312 is adjusted piece 309 drive moving contacts 305 by balance and moved.
Wherein, described soft magnetic bodies 312 is soft magnetism rods.
Because two coils of the actuating mechanism of ground-fault interrupter of the present invention are consumed power at short notice only, is that zero-power is connected during connecting, and therefore can save a large amount of energy.
Fig. 3 has shown and utilizes static pressure balance principle of the present invention to realize the graph of a relation that moving contact of the present invention and fixed contact reliably contact.
Referring to Fig. 3 a, balance adjustment rack 308 is socketed on the soft magnetic bodies 312, and the two ends of this balance adjustment rack 308 are provided with storage tank respectively, places in it and adjusts piece 309.

Referring to Fig. 3 d, under the downforce effect of a fixed contact (for example right-hand member fixed contact 203 of Fig. 3 c), adjust piece 309 other end perks to a moving contact.Another moving contact is reliably contacted with another fixed contact (for example left end fixed contact 203 of Fig. 3 c).
This shows, the present invention realizes that by the principle of static pressure balance moving contact contacts with the reliable of fixed contact, just, balance in the storage tank of balancing stand 308 is adjusted an end of piece 309 under the suppressing action of the static pressure of a fixed contact, make other end perk, thereby force another moving contact reliably to contact with another fixed contact, this is similar to the principle of seesaw, and an end presses down and makes other end perk.Therefore the present invention can realize that whole moving contacts contact with whole the reliable of fixed contact.
The course of work of the actuating mechanism of ground-fault interrupter is described below in conjunction with Fig. 1 and Fig. 2.
When initial condition, under retainer spring 307 effects, GFCI punishes disconnected state, (K in respect to Fig. 4 when pressing reset key (RESET) as described in Figure 1
3) closing coil 310 is (with respect to coil J among Fig. 4
1) charged, draw magnetic field in the formation, under the magneticaction in this magnetic field, soft magnetism rod 312 moves on rapidly, makes soft magnetism rod 312 and permanent magnet 202 adhesives, and because of balancing stand 308 be an one with soft magnetism rod 312, thereby balance goes up shipper pole simultaneously and moves on the movable contact spring 305 and move.Finish GFCI with static contact 203 connections and connect process, its on-state as shown in Figure 2.
Otherwise, when hindering electric current and other reasons for some reason, make broken coil 312 charged, form drop-down magnetic field, this moment, soft magnetic bodies 312 drop-down electromagnetic forces and retainer spring 307 were combined into greater than permanent magnet and soft magnetic bodies the suction-combining force, balancing stand were moved down, to making the GFCI disjunction rapidly.
Can find out that from last surface analysis just the actuating mechanism characteristics are: 1, GFCI connects and keeps relying on the electromagnetism the suction-combining force of permanent magnet and soft magnetic bodies, does not need the closing coil energising thereby does not have power consumption.2, different other GFCI of GFCI connect with mechanical force, are suitable for Long-distance Control and connect disjunction with electromagnetic force.
