Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As it is shown in figure 1, the distributed serial of the duplicate protection of the present embodiment compensates system, including being arranged in power distribution cabinet
Series compensation capacitor 11, voltage limiter 13, current limliting antivibrator the 12, first high-speed switch 14, current-limiting resistance the 16, second high-speed switch
17, current collector 18 and bidirectional triode thyristor 15, current limliting antivibrator 12 is connected on the end of incoming cables compensating capacitor 11, voltage limiter 13
One end be connected with the end of incoming cables of current limliting antivibrator 12, its other end with compensate capacitor 11 leading-out terminal be connected, first is quick
Switch 14 is connected in parallel on the two ends of voltage limiter 13, and one end of current-limiting resistance 16 is connected with the end of incoming cables of current limliting antivibrator 12, its another
End is connected with the leading-out terminal compensating capacitor 11 with current collector 18 through the second high-speed switch 17 successively, bidirectional triode thyristor 15
Two ends are connected with the end of incoming cables of current limliting antivibrator 12 and the leading-out terminal of compensation capacitor 11 respectively.
In the present embodiment, current limliting antivibrator 12 is in parallel is formed by inductance L and resistance R.First high-speed switch 14 and second
High-speed switch 17 controls it by the controller being arranged in power distribution cabinet respectively and cut-offs.First high-speed switch 14 and second is quickly opened
Close 17 and be vacuum circuit breaker.
Operation principle is as follows: when the terminal voltage of series compensation capacitor 11 exceed can two-way control silicon 15 time, this is two-way controlled
Silicon 15 turns on, thus series compensation capacitor 11 short circuit, prevents series compensation capacitor 11 from damaging because of overvoltage；When series connection is mended
Repaying after capacitor 11 protected, series compensation capacitor 11 is discharged by Intelligent discharge system immediately, discharges series compensation capacitor
Electric energy in 11；When the terminal voltage of series compensation capacitor 11 drops to bidirectional triode thyristor 15 return voltage, bidirectional triode thyristor 15
Disconnecting immediately, now high-speed switch 14 closes a floodgate, and this series compensation capacitor 11 is protected by high-speed switch 14；When short trouble excises
After, when line current returns normal value, controller sends separating brake order, and high-speed switch 14 disconnects, and makes series compensation capacitor 11
Input circuit runs.When bidirectional triode thyristor 15 outlet fault or current collector gather electric current beyond preset range time, its
Second high-speed switch 17 quick-make, now series compensation capacitor 11 is protected by the second high-speed switch 17.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the protection that this utility model claims determine
In the range of.
