Description
Technical field
The utility model belongs to disconnecting switch technical field, is specifically exactly to be related to a kind of flatly moving type contact of disconnecting switch
System.
Background technique
The word explanation of switch is to open and close.It refers to that one can make open circuit, make current interruptions or make it
Flow to the element of other circuits.The most common switch is the electromechanical equipment for allowing people to operate, wherein there is one or several contacts.Contact
" closed " (closed) indicate contact conducting, allow electric current flow through；" open circuit " (open) of switch indicates that contact is not turned on shape
At open circuit, electric current is not allowed to flow through.The developing history of switch is developed to from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electrics control equipment, the function of switch is more and more, and safety is also got over
Come higher, rotary switch is a kind of common switch, by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding specific position of state is determined to prevent rotary operating device from being operated without permission.Rotary isolation switch is widely applied
In electric system, for example, photovoltaic, wind-powered electricity generation etc..Such as in photovoltaic system, the lesser electric current that is generated in each photovoltaic cell
It is combined in parallel so as to the electric current or general power needed for being provided using system.
Have in existing switch one is disconnecting switch, disconnecting switch realizes contact system frequently with rotary or flatly moving type
Engagement and disjunction, wherein as shown in figure 1 and 2, existing flatly moving type contact system be only used for connect disjunction lower voltage
It is controlled with the circuit of lower-wattage, dynamic and static contact is in gate-dividing state, in order to improve the interrupting performance of breaker, dynamic and static contact
Between need to be arranged to it is biggish open away from, but dynamic/static contact is arranged to compared in the case of large opening, moving contact with it is adjacent another
Electric clearance between one phase static contact will become closely, and can reduce the interrupting performance of breaker device, especially connect disjunction height
When the circuit of voltage, it is just unable to satisfy the switch control requirement of electric system.
Utility model content
The purpose of this utility model is difficult to aiming at above-mentioned existing disconnecting switch flatly moving type contact system electric clearance
Setting is especially difficult to meet the technological deficiency for connecting the performance requirement of disjunction high voltage circuit, provides a kind of disconnecting switch
Flatly moving type contact system, by the improvement to existing flatly moving type contact system structure, make flatly moving type contact system moving contact and
Electric clearance between the static contact of adjacent another phase increases, and improves its interrupting performance, meets and connects disjunction high voltage circuit
Performance requirement.
Technical solution
In order to achieve the above technical purposes, the flatly moving type contact system of disconnecting switch provided by the utility model, it includes
Moving contact component and static contact component, the engagement and disjunction of the moving contact component and static contact component can be realized disconnecting switch
On-off, it is characterised in that: the moving contact component includes sliding block, and moving contact fills on the slide block, and the sliding block is located at institute
It states and is provided with boss on the adjacent another corresponding side of phase static contact of moving contact and can increase the moving contact and described adjacent
Another phase static contact between electric clearance.
Further, all it is arranged between the moving contact and adjacent another phase static contact on the two sides of the sliding block
There is boss.
Preferably, the boss is L-type or bobbin type.
Beneficial effect
The flatly moving type contact system of a kind of disconnecting switch provided by the utility model, by being located on the two sides of sliding block
Boss is all set between moving contact and adjacent another phase static contact, makes the moving contact of flatly moving type contact system and adjacent another
Electric clearance between the static contact of phase increases, and improves its interrupting performance, meets the performance requirement for connecting disjunction high voltage circuit.
