Abstract
The invention discloses a method for controlling a switching controller. Characteristic analysis is performed on system current change and system voltage change, and the type of a system fault can be determined. On the condition that close-in short-circuit occurs in a branch circuit, large short-circuit current and great voltage reduction occur, and the branch circuit is switched off. On the condition that power failure accidents such as upper switch tripping occurs in a working power supply, the current drops to zero and voltage drops continuously, switching is performed immediately. According to the method of the invention, an action signal is transmitted in 2ms on the condition that a short-circuit fault or power fault occurs in a power supply system. Through performing characteristic analysis on the system current change and the system voltage change, the type of the system fault can be determined, and a corresponding switching strategy is adopted.
Description
Technical field
The present invention relates to technical field of electric equipment, specially a kind of switch controller control 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 switch controller control 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 switch controller control method, device scheme is such as
Under：
To system power, voltage change signature analysis it can be determined that system failure type, there is near region inside this branch road
When short-circuit, short circuit current is big, and voltage declines to a great extent, and now cuts off branch road；
When working power occurs the power outages such as higher level's switch jump, electric current is zero, voltage continuous decrease, carries out immediately
Switching.
Compared with prior art, the invention has the beneficial effects as follows：The present invention can be short-circuited fault or mistake in power-supply system
Send actuating signal in electric 2ms, it can be determined that system failure type, take by system power, voltage change signature analysis
Corresponding Switching Strategy.
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 switch controller control method, its scheme is as follows：
To system power, voltage change signature analysis it can be determined that system failure type, there is near region inside this branch road
When short-circuit, short circuit current is big, and voltage declines to a great extent, and now cuts off branch road；
When working power occurs the power outages such as higher level's switch jump, electric current is zero, voltage continuous decrease, carries out immediately
Switching.
The present invention can send actuating signal in power-supply system is short-circuited fault or dead electricity 2ms, by system power,
Voltage change signature analysis, it can be determined that system failure type, takes corresponding Switching Strategy.
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 switch controller control method is it is characterised in that its scheme is as follows：
To system power, voltage change signature analysis it can be determined that system failure type, there is near region short circuit inside this branch road
When, short circuit current is big, and voltage declines to a great extent, and now cuts off branch road；
When working power occurs the power outages such as higher level's switch jump, electric current is zero, voltage continuous decrease, is cut immediately
Change.
