Abstract
A multi-tap arc suppression coil comprises loads of the primary winding, the secondary winding and the secondary coil, which is characterized in that the stepless adjustment of the primary multi-tap and the secondary thyristor or the step adjustment of the contactor are available, and has the advantages that it is not required to maintain control signal for long time, even if the control device is powered off, arc suppression coil can still remain on the tracking position. The coil is an ideal multi-tap arc suppression coil, which has the advantages of simple structure, high reliability, being able to quickly, dynamically, continuously make a stepless fine adjustment.
Description
One, technical field:
The utility model relates to a kind of arc suppression coil, and particularly a kind of combining once has level to transfer circle and secondary controllable silicon step-less adjustment or contactor to have level to regulate the turn-adjusting of both advantages with transferring arc suppression coil.
Two, background technology:
Usually adopt the arc suppression coil that is installed in the electric power system neutral point with the capacitance current of bucking-out system when the single phase ground fault in the present electric power system, make earth point electric arc be easy to extinguish.But in present arc suppression coil, also there are various defectives.Such as, induction-regulated, capacitor tuning type control signal need long-term the maintenance, after the control device outage. and arc suppression coil can not remain on tracing positional; Complex structure, defectives such as poor reliability.
Three, summary of the invention:
The purpose of this utility model is that a kind of turn-adjusting of design is with transferring arc suppression coil, this arc suppression coil tracing positional machinery keeps, control signal does not need long-term maintenance, even control device outage, arc suppression coil still can remain on tracing positional, simple in structure, the reliability height is in order to overcome the deficiencies in the prior art.
The purpose of this utility model can reach by following embodiment: this turn-adjusting is characterized in that with transferring arc suppression coil to be made up of the load of winding, secondary winding and a secondary winding load is a tunable load.
The utility model load has several, and K1 and Z1 are all arranged in each load, several K1 and Z1 is just arranged, i.e. K1 and Z1, K2 and Z2 in several loads ... in the load (n) Kn and Zn are arranged.
Z1-Zn in the adjustable load of the utility model be reactor, capacitor and resistor separately or constitute K1 ... Kn is contactor, both parallel connections of controllable silicon or uses one of them separately.
The by-pass cock of a winding of the utility model can be a plurality of single switch contacts or has the by-pass cock of carrying to regulate.
Advantage of the present utility model is that control signal does not need long-term maintenance, even the control device outage, arc suppression coil still can remain on tracing positional, simple in structure, the reliability height, it is many to regulate progression, governing speed is fast, is that a kind of comparatively desirable turn-adjusting is with transferring arc suppression coil.
Four, description of drawings:
Electrical schematic diagram when Fig. 1 is a plurality of single contact of winding by-pass cock of the utility model.
Fig. 2 is that a winding by-pass cock is the electrical schematic diagram that has when carrying by-pass cock.
Fig. 3 is that a winding by-pass cock is a plurality of single contacts, the electrical schematic diagram when the secondary winding by-pass cock is controllable silicon.
Fig. 4 is that a winding by-pass cock is for having the by-pass cock of carrying, the electrical schematic diagram when the secondary winding by-pass cock is controllable silicon.
Five, embodiment:
Shown in Fig. 1-4, this coil is made up of the load 3 of winding 1, secondary winding 2 and a secondary winding, it is characterized in that load 3 is tunable load.
The utility model load 3 has several, in each load 3 K1 and Z1 is arranged all, in several loads 3 several K1 and Z1 is just arranged, i.e. K1 and Z1, K2 and Z2 ... in the load (n) Kn and Zn are arranged.
Z1-Zn in the adjustable load 3 of the utility model be reactor, capacitor and resistor separately or constitute K1 ... Kn is contactor, both parallel connections of controllable silicon or uses one of them separately.
The by-pass cock of a winding 1 of the utility model can be a plurality of single switch contacts or has the by-pass cock of carrying to regulate.
