Adhesive, it under the guide effect of changement 2 11, overcomes the resistance of back-moving spring 2 12 by linkage 2 13 so that
Square shaft component 29 acts, while drives square shaft component 3 15 to act.So, the dynamic/static contact group C of right dynamic/static contact component 8 breaks
Open, dynamic/static contact group D closure, mother circuit turn-on, end of incoming cables " power supply I " at the same to " load I " with " load II " power supply.When entering
Line end " power supply II " supply power up it is normal when, after controller detects signal, electromagnet 2 10 again electric adhesive, pass through
Linkage 2 13 overcomes the resistance of back-moving spring 2 12 under the guide effect of changement 2 11 so that square shaft component 29
Action, while drive square shaft component 3 15 to act.So, the dynamic/static contact group C closures of right dynamic/static contact component 8, dynamic/static contact
Group D disconnects, and mother circuit disconnects, and " power supply I " is to " load I " power supplies, " power supply II " is to " load II " power supplies for end of incoming cables for end of incoming cables.
The present invention circuit operation principle be：Left dynamic/static contact component 7 and right dynamic/static contact component 8 are by 4 groups of dynamic/static contacts
Group A, B, C, D composition, its structure motion are controlled by switching mechanism one, switching mechanism two respectively, and two groups of realizations of A, B " touch by left sound
The combined floodgate of head assembly 7 " and disjunction, C, D two groups of realizations " combined floodgate of right dynamic/static contact component 8 " and disjunction.It is as shown in figure 4, normal
Under working condition, end of incoming cables two-way power supply is respectively to " loading I " and " load II " power supplies, dynamic/static contact group A, D disjunction, sound being touched
Head group B, C close a floodgate.
When end of incoming cables " when power supply I " supply power supplys go wrong, after controller detects signal, is driven by switching mechanism one
Dynamic circuit breaker opens the dynamic/static contact group B of lower end, go to upper end dynamic/static contact group A close a floodgate, by " power supply II " at the same to " load I " and
" load II " power supplies, now dynamic/static contact group B, D disjunction, dynamic/static contact group A, C are closed a floodgate.As shown in Figure 5.
When end of incoming cables, " when power supply II " supply power supplys go wrong, after controller detects signal, switching mechanism two drives
Dynamic/static contact group C is disconnected, the dynamic/static contact group D of lower end is closed a floodgate, is realized by " power supply I " is to two loads while powers, now
Dynamic/static contact group A, C disjunction, dynamic/static contact group B, D are closed a floodgate.As shown in Figure 6.
