Abstract
The invention discloses a kind of high-speed circuit breaker breaking method.Controller and breaker are integrally melted into switching device, by branch wire time control in 12ms, the change that voltage is caught in 2ms is started at the time of wherein switch controller drops suddenly from voltage, and is judged, switching command is sent if necessary；Breaker, which is connected to after switching command in 10ms, completes divide-shut brake action, and the branch road for having sensitive loads is switched on stand-by power supply and continued to run with.Divide-shut brake is carried out in the achievable 12ms of the present invention, the requirement protected to sensitive loads is fully met, when closing a floodgate, dash current is small, and the short circuit current flow Breaking capacity of breaker is improved during separating brake, improves the service life of breaker.
Description
Technical field
The present invention relates to technical field of electric equipment, specially a kind of high-speed circuit breaker breaking method.
Background technology
At present, as economic develops rapidly, people also increasingly increase for the demand of the energy, power plant, transformer station
Deng the construction of distribution facility, making the intellectuality of switchgear turns into a kind of essential demand, but general switch cubicle, no
It is only complicated, and timely and effectively can not display running status, operation difficulty is significantly increased, while employee
There is no high identification when operation, extremely easily cause failure, and the improper behaviour of layman can not be avoided
Make, switch cubicle is the work when, its service behaviour of temperature and humidity strong influence can notably cause security incident, and
Switch cubicle is needed with very many functions, and substantial amounts of equipment makes switch cubicle be difficult to one by one show operational data, simultaneously
Detection and the difficulty safeguarded are added, the current market demand is thus difficult in adapt to.
The content of the invention
It is an object of the invention to provide a kind of high-speed circuit breaker breaking method, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of high-speed circuit breaker breaking method, its scheme is such as
Under：
Controller and breaker are integrally melted into switching device, by branch wire time control in 12ms, wherein switching control
Device starts at the change that voltage is caught in 2ms at the time of drop suddenly from voltage, and judges, switching command is sent if necessary；
Breaker, which is connected to after switching command in 10ms, completes divide-shut brake action, the branch road for having sensitive loads is switched to standby
Continued to run with power supply.
Compared with prior art, the beneficial effects of the invention are as follows：Divide-shut brake is carried out in the achievable 12ms of the present invention, it is completely full
The requirement that foot is protected to sensitive loads, when closing a floodgate, dash current is small, and the short circuit current flow that breaker is improved during separating brake cut-offs appearance
Amount, improves the service life of breaker.
Embodiment
The technical scheme in the embodiment of the present invention is clearly and completely described below, it is clear that described embodiment
Only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
A kind of high-speed circuit breaker breaking method, its scheme is as follows：
Controller and breaker are integrally melted into switching device, by branch wire time control in 12ms, wherein switching control
Device starts at the change that voltage is caught in 2ms at the time of drop suddenly from voltage, and judges, switching command is sent if necessary；Open circuit
Device, which is connected to after switching command in 10ms, completes divide-shut brake action, and the branch road for having sensitive loads is switched on stand-by power supply and continues to transport
OK.
Divide-shut brake is carried out in the achievable 12ms of the present invention, the requirement protected to sensitive loads is fully met, when closing a floodgate, punching
Hit that electric current is small, the short circuit current flow Breaking capacity of breaker is improved during separating brake, improve the service life of breaker.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
