Background technique

In electrical power distribution apparatus, while twin-power switch is used for protection circuit and equipment from fault harms such as overload, short circuits, It more can quickly automatically switch another way backup power source, guarantee the continued power of route.With reusing the increasingly wider of place, The electricity consumptions such as equipment it is increasing, the demand to large capacity twin-power switch is increasing.

Large capacity dual power supply currently on the market mainly links up use by two table frame breakers, and volume is big, It is at high cost, it is unable to satisfy some demands for reusing place.

Chinese patent application 201210050095.9 discloses a kind of interlock for dual-power transfer switch, including Switching mechanism, operating mechanism, indicating mechanism and interlocking mechanism；Switching mechanism includes switching main shaft and reversing plate, the side of reversing plate Sliding surface is equipped at edge；Frame and floodgate semiaxis are equipped in operating mechanism；Indicating mechanism includes main indicator, master reset spring, pair Reset spring；Interlocking mechanism includes interlock plate, main blocking lever and duplicate invoice locking bar；The basic configuration of interlock plate is provided with three protrusive boards Y shape, center is rotatably arranged on the frame of operating mechanism；An interlocking hole is equipped in interlock plate on each protrusive board, wherein One protrusive board interlocks hole by it and is set in floodgate semiaxis, and another two protrusive board interlocks Kong Yuzhu blocking lever by it or duplicate invoice is locked Bar is connected；The other end of main blocking lever is connected with main indicator, and duplicate invoice locking bar is connected with secondary indicator.The invention can be according to cutting Change owner axis status limits floodgate semiaxis by the linkage of indicating mechanism, effectively prevent the generation because of maloperation, improves Security performance.But the inventive structure is relative complex, operation is relatively inconvenient, and also some are insufficient for the degree of reliability of conversion electric power, It is unable to satisfy some demands for reusing place.

Summary of the invention

Object of the present invention is to: for being difficult to ask in the power supply automatic conversion for reusing place and carrying out high current in the prior art Topic provides a kind of frame integral type dual power supply, and power supply is carried out by two-way power supply, when common power cut-off or failure, helps It quickly cuts off and converts to another way power supply.

Specifically, the present invention adopts the following technical solutions realize:

A kind of frame integral type dual power supply, including switching mechanism, operating mechanism and two groups of contact assemblies, the sets of contacts Part includes moving contact and static contact, and two moving contacts are connected with each other by connecting shaft, and shaft, two dynamic touchings are provided in connecting shaft Head can be rotated centered on the shaft, and there are two branches for one end setting of the switching mechanism, be connected respectively with moving contact, The other end preselects the direction of combined floodgate by stirring for handle, and operating mechanism is by realizing conversion to the promotion of switching mechanism Promotion of the mechanism to the static contact in the combined floodgate direction of pre-selection, makes the contact assembly of this one end close a floodgate.

Further, the switching mechanism includes handle and turntable, passes through first connecting rod machine between the handle and turntable Structure linkage, links between the turntable and a moving contact by second connecting rod mechanism, the turntable and another moving contact it Between linked by third connecting rod mechanism.

Further, the first connecting rod mechanism includes first connecting rod and rotor plate, and the first waist is provided on the turntable One end of type hole, first connecting rod is limited by waist-shaped hole, and the other end is hinged with rotor plate, is movably set in the middle part of first connecting rod In shaft, the rotation of rotor plate is by handle drives.

Further, the second connecting rod mechanism includes second connecting rod, third cantilever and the second main shaft, is set on the turntable It is equipped with the second waist-shaped hole, one end of second connecting rod is limited in the second waist-shaped hole, and one end of the other end and third cantilever is hinged, third The other end of cantilever is fixed on the second main shaft, and connecting rod is further fixed on the second main shaft, and connecting rod is connected with static contact, and according to The rotation of two main shafts and push or pull on static contact, the elastomeric element for stretching energy storage is also connected on the third cantilever； The structure of the third connecting rod mechanism is identical as second connecting rod mechanism.

Further, the operating mechanism includes the first main shaft, the second cantilever and sliding block, and one end of second cantilever is solid Due on the first main shaft, the other end is hinged with sliding block, and the shaft for being used to support the rotor plate rotation is set on sliding block.

Further, when closing a floodgate with major loop, corresponding elastomeric element is stretched to store energy, elastomeric element when separating brake In energy release.

Further, second waist-shaped hole on the turntable is bent along the circumferencial direction of turntable.

Further, the rotor plate is in isosceles triangle, and its vertex is connected with first connecting rod, the bottom on bottom edge and handle Portion abuts against.

Further, the vertex of the rotor plate is provided with waist-shaped hole, and the end of the first connecting rod is limited in the waist It is moved in type hole.

Further, first group of contact assembly is arranged in the top half of the ontology, for upper major loop, when which closes a floodgate Main power source is connected, another group of contact assembly is arranged in the lower half portion of ontology, and for lower major loop, which connects standby electricity when closing a floodgate Source.

Beneficial effects of the present invention are as follows:

The present invention allows two-way power supply to simultaneously switch off, but only allows power supply connection all the way.Due to a present invention only behaviour Make mechanism, when power supply is in on-state all the way, another way power supply, which can not close a floodgate, to be powered on, so the present invention reliably protects The safety of major loop is hindered；Present invention utilizes the large capacity rated current of frame short-circuiting device and disjunction indexs and integrated ontology to add The structure feature of one mechanism reduces product space and cost.
