The switching switch has a quick switching speed, cannot be adhered to a contact due to inrush current during switching closing, has no re-ignition at the time of disconnection, generates no over voltage, reduces the probability of capacitor damages, has a low investment cost and saves energy and electricity.
Description
Technical field
The utility model relates to a kind of fling-cut switch, is a kind of high-pressure reactive compensation capacitor switching switch specifically.
Background technology
In the electric power transportation, the appearance of reactive power causes the power dissipation of circuit and power supply unit to increase, and shunt capacitor carries out power back-off on the circuit of therefore being everlasting.In these compensation arrangements, fling-cut switch is a key device, and its performance is directly connected to the reliability of running gear.Generally require service speed fast, electric stress is less, is fit to frequent operation, takes into account operating cost.
At present, the fling-cut switch of inactivity compensation device mainly contains three kinds of forms on the market.First kind, directly use contactor (relay) control switching, shortcoming is an easy firing in the switching process, produces overvoltage, and switching degree of gushing is big, produces electric arc, and time delay is longer, and reliability is differential; Second kind, use thyristor control switching, shortcoming is that withstand voltage properties is poor in the thyristor use, and the pressurized peak generates heat easily, and long-time running needs more thyristor in parallel, and will set up radiator, the cost of investment height; The third is the above two combination, jointly controls one group of switching with one a group of thyristor and a winding tentaculum, and its defective is that thyristor and contactor outfit are many, and utilization rate of equipment and installations is lower, and cost is also higher.
Summary of the invention
The purpose of this utility model is for solving the problems of the technologies described above the deficiency of existence, the high-pressure reactive compensation capacitor switching switch of a kind of quick switching, saves energy being provided.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: a kind of high-pressure reactive compensation capacitor switching switch, comprise casing, vacuum interrupter and wiring porcelain vase, vacuum interrupter and wiring porcelain vase are separately positioned on the last end face and bottom surface of casing outside, in casing, be provided with permanent magnet drive mechanism, the actuating bar of permanent magnet drive mechanism is connected with a cross bar, leading-out terminal in the vacuum interrupter is connected with the wiring porcelain vase by lead, and the moving contact connecting rod of vacuum interrupter links to each other with cross bar.
The outside of described casing also is provided with the folding pointer, and the folding pointer is connected with cross bar by plectrum.
Described permanent magnet drive mechanism is connected with peripheral control unit.
Described permanent magnet drive mechanism has one or more.
The utility model is used for controlling the input and the excision of high-pressure reactive compensation device capacitor group, the capacitor winding is at the wiring porcelain vase end of fling-cut switch, control unit by the outside moves according to permanent magnet drive mechanism in the actual conditions control fling-cut switch of circuit, and the separation or the closure of drive vacuum arc-extinguishing chamber contact, thereby realization is to the input and the excision of capacitor group.
The beneficial effects of the utility model are:
1, uses the folding of permanent magnet drive mechanism drive switch, realize the quick switching of capacitor group.
2, switching speed is fast, and the switching pass is fashionable can not had during disjunction and restrike because of the adhesion contact that shoves, and overvoltage can not occur, has reduced the probability that capacitor damages.
3, cost of investment is lower, energy-conservation economize on electricity.
