Description
[technical field]
The invention belongs to Power System Electromagnetic Compatibility research field, relate to a kind of breaker operator controller for circuit breaker deciliter time controling and method of operation.
[background technology]
Along with power industry develop rapidly, transformer substation voltage grade improves constantly, weak current equipment based on microelectronics detection technique and Computer Control Technology is applied to transformer station more and more widely, electromagnetic compatibility be no longer only one to electrically utilize relevant technical problem, become one is stablized social safety, the quality assurance of living environment etc. is significant society, economic problems.
President Obama of the U.S. in 2009 proposes the development plan of investment intelligent grid, formally intelligent grid construction is incorporated American National economic development planning as a new forms of energy development strategy, after European Union and the Japanese Deng Guoyeji U.S., launch respectively the intelligent grid development plan of oneself.State Grid Corporation of China also disclosed the development plan of China's intelligent grid in 2009, the intelligent grid of China is defined as " strong intelligent grid ".At present, during the strong intelligent grid of China is comprehensively built, it is bulk transmission grid that target is built exactly with extra-high voltage grid, the sturdy power grid of other each level Grid stable coordination development, it can realize resource and the energy distributing rationally in a big way, can be ensured safety reliable supply of electric power, and will realize the informationization of electrical network, automation and interactive on the basis of sturdy power grid, the implication of Here it is strong intelligent grid " intelligence "." three change " feature of intelligent grid, basis is exactly electronic technology, and this just requires that the electronic mutual inductor playing detection effect in electric power system must can adapt to the demand of intelligent grid.
As switchgear of paramount importance in electric power system; important function control is played to power circuit and power equipment, regulating and protect; its figure spreads all over each corner of electric power system; but in transformer station; produce electromagnetic disturbance; and cause electronic mutual inductor to send rub-out signal; and then cause the accident of protection misoperation; the accident causing equipment to put into operation time even serious; the most typical with isolating switch; and along with the continuous rising of electric pressure, the continuous increase of net capacity, the harassing and wrecking that isolator operation produces are more and more stronger.When power system operation, switch will often operate, as isolating switch suit the unloaded bus of high pressure, circuit breaker suits high voltage bus, circuit breaker suits high-tension line, Circuit Breaker Switching Capacitor banks, also have the switching operation etc. of no-load transformer and reactor, when switching manipulation, high voltage bus can produce complicated transient voltage and electric current, and produce transient electromagnetic field at bus surrounding space.Not only amplitude is higher for these Transient Electromagnetic processes; and the frequency component comprised is from tens KHZ to MHZ up to a hundred; this will produce electromagnetic disturbance to the electronic mutual inductor worked in transformer station, thus affects the normal work of electronic mutual inductor, and then causes electric network protection malfunction or damage.Therefore, in the face of the reality of electrical network fast development, the electromagnetic disturbance characteristic testing research carrying out electronic mutual inductor is imperative.

5. the method for operation of a kind of breaker operator controller for circuit breaker deciliter time controling according to claim 1, it is characterized in that, comprise: the gear of gear control switch K1 is turned round to conjunction-t-stepping, the terminal 1 of gear control switch K1, the terminal 3 of 2 connection gear control switch K1, the terminal 3 of time-delay relay Y, 5 connect, power supply signal is first after time-delay relay Y, control photoisolator G1 to close, make control signal by the energising of photoisolator G1 control relay J, thus control circuit breaker conjunction port powers on, circuit breaker is made to carry out closing operation, then time-delay relay Y is after set delay time t, and the terminal 3,5 of time-delay relay Y disconnects, and the terminal 3,4 of time-delay relay Y connects, thus the power supply of signal to photoisolator G1 of cutting off the electricity supply, cut off the power supply of control signal to relay J, point closing operation eventually through relay J is shifted gears, and makes control circuit breaker divide port to power on, and makes circuit breaker carry out a point operation.
6. the method for operation of a kind of breaker operator controller for circuit breaker deciliter time controling according to claim 1, is characterized in that, comprising: turned round by gear control switch K1 and close gear to single point of list, the terminal 1,2 of gear control switch K1 connects terminal 4; Power supply signal serial connection is to single point of single combination switch K2; Single point of single combination switch K2 is gone to single stepping, and terminal 1 and the terminal 3 of single point of single combination switch K2 are connected, and now photoisolator G1 and photoisolator G2 does not all work, relay J dead electricity, and circuit breaker is in a point state.
7. the method for operation of a kind of breaker operator controller for circuit breaker deciliter time controling according to claim 1, is characterized in that, comprising: turned round by gear control switch K1 and close gear to single point of list, the terminal 1,2 of gear control switch K1 connects terminal 4; Power supply signal serial connection is to single point of single combination switch K2; Single point of single combination switch K2 is gone to single stepping, and terminal 1 and the terminal 4 of single point of single combination switch K2 are connected, and now photoisolator G2 connects, and relay J powers on, and carries out closing operation to circuit breaker.
