In more important place, such as hospital, airport, harbour, depend on double power supply automatic transfer switch to provide continuous power supply.
The double power supply automatic transfer switch that the common current country uses is most widely bikini automatic switching control equipment, should
Wiring is two road power supplys, and the using and the reserved are standby each other, is combined by two catalysts or chopper or load-break switch,
Electric interlock and mechanical interlocking are all provided with typically between two Switch main bodies, in case two power sources in parallel.Under normal circumstances can be by
Any in two road power supplys powers all the way, and another road is standby；When normally being had a power failure using power failure, the automatic change-over is certainly
It is dynamic that load transition is powered to another power supply, three kinds can be divided into according to its various combination and operation principle：First contactor formula,
It is combined by two catalysts, the earliest one kind for being, the device circuit of this combination is simple, low price, but
It is its poor reliability, the long-term live line work of functional contact device coil, greatly, current designer is fewer and feweri to adopt this for power consumption
Plant combination；Second is CB level products, and it is formed by two air-break+controller combinations, with mechanical interlocking and electricity
Gas is interlocked, and protection switch and switching switch are combined together, and existing defencive function has handoff functionality again, and simple system can
Lean on；The third PC level product, PC levels product are typically encapsulated in a complete housing, are superimposed by two load-break switch
Form with controller combination, with mechanical interlocking and electric interlock, can be seen that from three of the above mode and turn in traditional dual power supply
Change, be realizing, to prevent from running without power sources in parallel by mechanically and electrically interlocking.
When interlocking unsuccessfully occurs that the state of two different electrical power parallel runnings causes load equipment scaling loss.

It is connected on action contact frame, the other end withstands on the outside of movable contact spring；Movable contact spring encloses to form inlet wire moving contact and outlet moving contact outwardly；It is dynamic
Three installing holes are circumferentially provided with tactile frame；Column is arranged on action contact frame by the installing hole；Spring is arranged with column；
Spring is located between two movable contact springs and is contacted with two movable contact springs.
Preferably, the movable contact block is one section of triangular shaft between two action contact frames, movable contact spring is centrally formed and moves
The vee gutter that the triangular shaft of contact base is adapted, also forms and vee gutter identical reed trough on reed.In assembling,
The hole of same shape and groove preferably can be fitted assembling, with preferable assembly performance.
Preferably, the opening of the vee gutter is arranged on outlet moving contact end.
Preferably, the triangular shaft vee gutter opening while formed with both sides action contact frame identical arc surface,
Have this switch contact preferably structural.
Preferably, the inside edge of inlet wire moving contact and outlet moving contact forms cambered surface, rounding off, it is to avoid line of damaging connects
Head.
This utility model adopts two structure of contact terminals, switch to connect primary, spare power supply respectively by rotation, and an inlet wire is moved
Contact switches between two power supplys, and an outlet moving contact switches between outlet terminal, can effectively prevent two different electricity
Source parallel running, dynamic contact mechanism simple structure, action are convenient and swift, and low production cost can be widely applied for dual power supply
In switch operating.
