Description
Technical field
The utility model relates to a kind of parts of dual-power transfer switch, especially a kind of dynamic contact mechanism of dual-power transfer switch.
Background technology
Double power supply automatic transfer switch to be used in electric power system, when main electricity breaks down, trouble power can being avoided to power to the load, reliably selecting again qualified power supply to drop into normal operation, to ensure that power supply is uninterrupted.The place of general use outbalance, such as hospital, airport, harbour, all rely on double power supply automatic transfer switch to power to provide continuous print.
The double power supply automatic transfer switch of common current domestic use is bikini automatic switching control equipment the most widely, this wiring is two road power supplys, the using and the reserved, for subsequent use each other, combined by two contactors or circuit breaker or load-break switch, generally electrical interlock and mechanical interlocking is all established, in case two power sources in parallel between two Switch main bodies.Any road under normal circumstances in the power supply of Ke You bis-road powers, and another road is for subsequent use; When normal use power failure has a power failure, this automatic change-over automatically by load transition to another Power supply, the three kinds: first contactor type can be divided into according to its various combination and operation principle, it is combined by two contactors, the one being the earliest, the device circuit of this combination is simple, low price, but its poor reliability, the long-term live line work of functional contact device coil, power consumption is large, this combination of the fewer and feweri employing of current designer; The second is CB level product, and it is combined by two air circuit+controllers, and have mechanical interlocking and electrical interlock, and protection switch and diverter switch are combined, existing defencive function, has handoff functionality again, and system is simple and reliable; The third PC level product, PC level product is generally encapsulated in a complete housing, combined by two load-break switchs superpositions and controller, there is mechanical interlocking and electrical interlock, as can be seen from above three kinds of modes, in traditional double transfer switch, there are two groups of moving contacts, be realized by machinery and electrical interlock, prevent from running without power sources in parallel.The state that unsuccessfully there will be two different electrical power parallel runnings when interlocking causes load equipment scaling loss.
Summary of the invention
For above-mentioned reasons, it is simple that the purpose of this utility model is to provide a kind of structure, the dynamic contact mechanism of easy to operate dual-power transfer switch.
For achieving the above object, the utility model adopts a kind of dynamic contact mechanism of dual-power transfer switch, comprise movable contact block, two panels movable contact spring, two panels reed, movable contact block both sides form the action contact frame of annular, two panels movable contact spring is enclosed within the movable contact block between two action contact frames relatively, two panels reed is separately positioned between the action contact frame of two panels movable contact spring and respective side, described movable contact spring is that Y type forms three moving contacts towards outer ring, three moving contacts are respectively an inlet wire moving contact of one end and two outlet moving contacts of the other end, reed side is connected on action contact frame, the other end withstands on outside three moving contacts of movable contact spring.
It is one section of square shaft that the utility model is set to described movable contact block further between two action contact frames, is formed centrally the square groove suitable with the square shaft of movable contact block in described movable contact spring, and reed also forms the reed trough identical with square groove.
The opening that the utility model is set to described square groove is further arranged between two outlet moving contacts.
The utility model is set to described square shaft at the opening of square groove further while form the arc surface identical with both sides action contact frame.
The inside edge that the utility model is set to described moving contact further forms cambered surface.
The beneficial effects of the utility model are contacts of employing three knife-switch structures, switch connects primary, spare power supply respectively by rotating, an inlet wire moving contact switches between two power supplys, the binding post of two power supplys can be arranged on the same side, two outlet moving contacts coordinate the rotation of contact to connect respectively at same outlet terminal, effectively can prevent two different electrical power parallel runnings, dynamic contact mechanism structure is simple, and action is convenient and swift.
