Embodiment
Fig. 1 and Fig. 2 show the schematic diagram of the actuating mechanism of ground-fault interrupter of the present utility model, comprising:
A permanent magnet 202 is positioned at the position with a soft magnetic bodies 312 vicinities;
A soft magnetic bodies 312 is positioned at a sleeve, and this soft magnetic bodies 312 drives moving contact 305 and moves up and down under the effect of magnetic force;
A closing coil 310 is wrapped in an end of the nearly permanent magnet 202 of sleeve;
A broken coil 311 is wrapped in an end of the permanent magnet far away 202 of sleeve;
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, it holds fixedly connected soft magnetic bodies 312 in addition.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 utility model are consumed power at short notice only, is that zero-power is connected during connecting, and therefore can save a large amount of energy.
According to Fig. 1, structure shown in Figure 2, can obtain reducing the method for the actuating mechanism energy resource consumption of ground-fault interrupter, this method comprises:
When resetting, the magnetic field that utilizes the energising of closing coil (310) short time to produce, provide one to start magnetic force, to impel a soft magnetic bodies to move along a direction, and with a permanent magnet adhesive, make soft magnetic bodies drive energising moving contact (305) thus and contact with energising fixed contact (203), thus the "on" position of maintenance circuit breaker;
When ground connection, reversal connection line or other fault take place, the magnetic field that utilizes the energising of broken coil (311) short time to produce provides a disjunction magnetic force, and soft magnetic bodies (312) is oppositely moved along opposite, thereby energising moving contact (305) is broken away from and the contacting of fixed contact (203), cut off the electricity supply thus.
Because the utility model is during reseting period and error protection, only therefore consumed power at short notice can save a large amount of energy.
Below in conjunction with Fig. 1 and Fig. 2 the course of work of the present utility model is described.
When initial condition, under retainer spring 307 effects, GFCI punishes disconnected state, (K in respect to Fig. 3 when pressing reset key (RESET) as described in Figure 1
3) closing coil 310 is (with respect to coil J among Fig. 3
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.
