Abstract
The present invention discloses a circuit breaking method of a high-speed circuit breaker. A controller and a circuit breaker are integrated so as to form a switch apparatus, and the switch on and off time is controlled within 12ms. From the time point of voltage plunge, the switch controller captures voltage change within 2ms, and determines that a switch instruction can be sent out if necessary. After receiving the switch instruction, the circuit breaker completes switch on and off within 10ms, so as to switch a branch with sensitive load to a standby power supply to run continuously. Through adoption of the method, the switch on and off can be carried out within 12ms, and the demand of protecting sensitive load is met., The impact current is low during switch on, and the short circuit current breaking capacity of the circuit breaker is improved during switch off, so that the service life of the circuit breaker is prolonged.
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, develop rapidly with economic, people also increasingly increase for the demand of the energy, power plant, transformer station
Deng the construction of distribution facility, the intellectuality of switchgear is made to become a kind of requisite demand, but general switch cubicle, no
Only complex structure, and can not timely and effectively running status be displayed, significantly increase operation easier, simultaneously employee
There is no high identification when operation, extremely easily cause fault, and the improper behaviour of layman cannot be avoided
Make, switch cubicle the work when, its service behaviour of temperature and humidity strong influence, notably can cause security incident, and
Switch cubicle needs there is very many functions, and substantial amounts of equipment makes switch cubicle be difficult to present operational data one by one, simultaneously
Increased detection and the difficulty safeguarded, be thus difficult in adapt to the current market demand.
Content of the invention
It is an object of the invention to provide a kind of high-speed circuit breaker breaking method, to solve proposition in above-mentioned background technology
Problem.
For achieving 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 is melted into switching device with chopper one, branch wire time is controlled in 12ms, wherein switching control
Device starts at, from the moment of the steep fall of voltage, the change catching voltage in 2ms, and judges, sends switching command if necessary;
Chopper completes divide-shut brake action in 10ms after being connected to switching command, the branch road having sensitive loads is switched to standby
Continue to run with power supply.
Compared with prior art, the invention has the beneficial effects as follows:The present invention can achieve in 12ms and carries out divide-shut brake, completely full
The requirement to sensitive loads protection for the foot, when closing a floodgate, dash current is little, and the short circuit current improving chopper during separating brake cut-offs appearance
Amount, improves the service life of chopper.
Specific embodiment
Below the embodiment it is clear that described is clearly and completely described to the technical scheme in the embodiment of the present invention
It is only a part of embodiment of the present 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 not making creative work, broadly falls into the model of present invention protection
Enclose.
A kind of high-speed circuit breaker breaking method, its scheme is as follows:
Controller is melted into switching device with chopper one, branch wire time is controlled in 12ms, wherein switching control
Device starts at, from the moment of the steep fall of voltage, the change catching voltage in 2ms, and judges, sends switching command if necessary;Open circuit
Device completes divide-shut brake action in 10ms after being connected to switching command, the branch road having sensitive loads is switched on stand-by power supply and continues fortune
OK.
The present invention can achieve in 12ms and carries out divide-shut brake, fully meets the requirement to sensitive loads protection, when closing a floodgate, punching
Hit that electric current is little, during separating brake, improve the short circuit current Breaking capacity of chopper, improve the service life of chopper.
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 the spirit or essential attributes of the present 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 requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.
Claims (1)
1. a kind of high-speed circuit breaker breaking method is it is characterised in that its scheme is as follows:
