Description

A kind of Fast Speed Vacuum Circuit Breaker
Technical field
The utility model relates to field of circuit breakers, particularly a kind of Fast Speed Vacuum Circuit Breaker.
Background technology
Circuit breaker refer to the electric current that can close, carry and cut-off under normal loop condition and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition in official hour.Circuit breaker can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current.At present, obtain a wide range of applications.
In prior art, divide-shut brake is carried out owing to needing enough power, high pressure, ultra-high pressure switch responsiveness are slower, branch wire time is long, add the recognition time of short trouble, by release unit short circuit, can not could have a power failure in time after waiting until at least 100ms after short trouble generation, Switching power when needing to grow very much.This just require to take control gap, power electronic element and zinc oxide arrester etc. auxiliary protection means.Therefore, conventional series capacitor installation inevitably exist bulky, involve great expense, the problem of technical sophistication, poor reliability, this also conventional just series capacitor installation is difficult to the reason applied at high pressure, supergrid.
Now be badly in need of a kind ofly can shortening branch wire time, cost-saving Fast Speed Vacuum Circuit Breaker.
Utility model content
In order to solve the problem, the utility model provides a kind of can shorten branch wire time, cost-saving Fast Speed Vacuum Circuit Breaker.
A kind of Fast Speed Vacuum Circuit Breaker in the utility model, comprise circuit breaker frame, vacuum interrupter, permanent magnetism fast controller, storage capacitor is provided with in described circuit breaker frame, it is characterized in that, also comprise cut-off overvoltage device, described cut-off overvoltage device is located at by vacuum interrupter, is connected with vacuum interrupter by galvanic circle, described galvanic circle is connected with insulating supporting loop, and described insulating supporting loop is connected with high-power permanent magnet operating mechanism.
In such scheme, described cut-off overvoltage device is nonlinear damping resistor.
In such scheme, also comprise AC/DC modular converter, described AC/DC modular converter is connected with permanent magnetism fast controller.
In such scheme, also comprise circuit breaker propelling mechanism, described circuit breaker propelling mechanism is located at circuit breaker frame bottom.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of can shorten branch wire time, cost-saving Fast Speed Vacuum Circuit Breaker.The circuit breaker of this practicality; can disjunction fast when running into fault; breaker open operation time≤6MS; breaker closing time≤16MS, thus protection visual plant, as generator; high-power transformer etc.; simultaneously can cost-saving creation profit, conventional generator circuit breaker after separating brake minimum need to wait 15 minutes after can close a floodgate, and the circuit breaker of this practicality only needs to wait 3 minutes even less.Fast Speed Vacuum Circuit Breaker is applicable to incoming line cabinet tailored version, can carry out the switching of quick power supply at important place and play corresponding protective effect, avoids the rear long time-switching power supply that has a power failure, in order to avoid cause damage.Fast Speed Vacuum Circuit Breaker has more standby independence; have more the ability of preparation electric motor protecting, can effective fault current limiting, the system after enlarging adopts Fast Speed Vacuum Circuit Breaker to be connected with between former electric power system; the equipment of former electric power system does not need answer increase-volume and change, and play can investment reduction simultaneously.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
Embodiment one:
As shown in Figure 1, the utility model is a kind of Fast Speed Vacuum Circuit Breaker, comprise circuit breaker frame 1, vacuum interrupter 2, permanent magnetism fast controller 3, storage capacitor 4 is provided with in circuit breaker frame 1, also comprise cut-off overvoltage device 5, it is other that cut-off overvoltage device 5 is located at vacuum interrupter 2, is connected with vacuum interrupter 2 by galvanic circle 6, galvanic circle 6 is connected with insulating supporting loop 7, and insulating supporting loop 7 is connected with high-power permanent magnet operating mechanism 8.Cut-off overvoltage device 5 is nonlinear damping resistor.
Also comprise AC/DC modular converter 9, AC/DC modular converter 9 to be connected with permanent magnetism fast controller 3.
When needs separating brake time, permanent magnetism fast controller 3 gives storage capacitor 4 with the signal of telecommunication, and storage capacitor 4 drives insulating supporting loop 7 to move downward, Fast Speed Vacuum Circuit Breaker and quick acting switching-off.
In vacuum interrupter of the prior art, can produce powerful overvoltage in the moment of divide-shut brake, overvoltage needs the time to bleed off, and therefore the time of divide-shut brake has no idea to shorten too much.And the utility model is connected to cut-off overvoltage device, because overvoltage can be transferred to self rapidly and discharge by the characteristic of nonlinear damping resistor, the speed of divide-shut brake therefore greatly can be promoted.
Embodiment two:
As shown in Figure 2, also comprise circuit breaker propelling mechanism 10, circuit breaker propelling mechanism 10 is located at circuit breaker frame 1 bottom.
When needs separating brake time, permanent magnetism fast controller 3 gives storage capacitor 4 with the signal of telecommunication, and storage capacitor 4 drives insulating supporting loop 7 to move downward, Fast Speed Vacuum Circuit Breaker and quick acting switching-off.
In vacuum interrupter of the prior art, can produce powerful overvoltage in the moment of divide-shut brake, overvoltage needs the time to bleed off, and therefore the time of divide-shut brake has no idea to shorten too much.And the utility model is connected to cut-off overvoltage device, because overvoltage can be transferred to self rapidly and discharge by the characteristic of nonlinear damping resistor, the speed of divide-shut brake therefore greatly can be promoted.
