Background technology
High-voltage circuitbreaker is the important equipment for ensureing safe operation of power system, it, which is acted on, is normally born for cut-offfing circuit
Carry electric current and short-circuit current.
It is usually longer for the transmission system of 363kV and above, its transmission line of electricity.When breaker closes zero load
When long line and automatic reclosing, due to capacitive rise effect, it will usually have the closing overvoltage of higher magnitude, this requires breaker needs
Equipped with the switching-on resistance for suppressing closing overvoltage and switching-on resistance switch.
Land resource is resource non-renewable on the earth, and the floor space of breaker is high-voltage circuitbreaker market competition
One important indicator.Reliability is another important indicator of breaker, using the breaker of linear motion due to no connecting lever etc.
Transmission parts, intermediate transmission link is few, reliability higher.But when circuit breaker voltage is higher ranked, a fracture is difficult to reality
The switch performance of existing breaker.
Utility model content
The technical problems to be solved in the utility model is：How while breaker floor space is reduced, meet high pressure
Demand of the breaker to break performance.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of linear motion band switching-on resistance
The arrangement of multi-break breaker, it is characterised in that：Including at least two main arc extinguishing units, each main arc extinguishing unit is sequentially connected in series
Afterwards, then with switching-on resistance switch connect；Each main arc extinguishing unit presses element in parallel, switching-on resistance with a main arc extinguishing unit respectively
Device and switching-on resistance switch in parallel.
Preferably, the main arc extinguishing unit uses SF6 arc extinguishing units or vacuum arc extinguishing unit.
Preferably, the main arc extinguishing unit presses element to use lumped capacitance.
It is highly preferred that each main arc extinguishing unit presses the capacitance of the lumped capacitance of element identical.
It is highly preferred that each main arc extinguishing unit presses the capacitance of the lumped capacitance of element not exactly the same.
Preferably, the main arc extinguishing unit presses element to use lumped resistance.
Preferably, connected between the main arc extinguishing unit and operating mechanism by the direct acting kind of drive.
Arrangement of the linear motion provided by the utility model with switching-on resistance multi-break breaker is in use, in open circuit
During device closes, main arc extinguishing unit first closes, switching-on resistance device input；After 7~11ms, switching-on resistance closes,
Switching-on resistance is shorted, and exits circuit.In breaker separation process, main arc extinguishing unit first separates, and divides after switching-on resistance switch
Open, switching-on resistance switch is not involved in main arc extinguishing unit arc extinguishing operation.
Compared with prior art, arrangement of the linear motion provided by the utility model with switching-on resistance multi-break breaker
Have the advantages that：
1st, connected using two or more main arc extinguishing units, meet the needs of high-voltage circuitbreaker is to break performance.
2nd, to ensure that the electric field stress that each main arc extinguishing unit is born in interrupting process is more divided equally, it is provided with pressure member
Part.
3rd, the direct acting kind of drive is used between main arc extinguishing unit and operating mechanism, reduces middle connecting lever transmission link, carries
Its high reliability.
4th, switching-on resistance switch is connected with main arc extinguishing unit, reduces breaker tank diameter, reduces breaker occupation of land
Area, improves its economy and the market competitiveness.
