Abstract

The utility model relates to a resin insulated dry arc suppression coil which belongs to the common components such as: a transformer or an inductor. An iron core is composed of an air gap column and an iron core column. The air gap column and the iron core column are respectively sheathed with a resin-insulated primary coil and a secondary coil. The utility model solves a problem existing in the prior art that a tapped dry extinguishing coil has the small current regulation range. The utility model has a capacitive (or nasty) load on the secondary coil, and then adjusts the capacity of the capacitive (or nasty) load, which can implement the extensive current stepless regulation. Moreover, the resin is used for insulation, which is more suitable for the places which have high requirements for fire prevention, explosion protection and no oil.

Description

The resin-insulated dry arc suppression coil

The utility model belongs to the general parts of transformer or inductor, particularly its iron core and coil.

Resin-insulated dry arc suppression coil in the prior art mainly is made up of iron core that has air gap and primary winding, and coil has tap, fetches the adjusting inductance by branch, to satisfy under the different running statuses of electrical network taking off the requirement of humorous degree.But, because structural reason, primary winding with the tap number be limited, thereby limited the Current Regulation scope of this type arc suppression coil.

The purpose of this utility model be the design a kind of do not have tap, can load-carrying resin-insulated dry arc suppression coil.

The utility model comprises the primary winding of unshakable in one's determination and insulation resin, and described iron core comprises air gap post and core limb, the primary winding of suit insulation resin on the air gap post, the secondary coil of suit insulation resin on the core limb.

Iron core of the present utility model comprises air gap post and core limb, and coil is divided into once and secondary coil, as long as be with capacitive (or perception) load on secondary coil, regulates the capacity of this capacitive (or perception) load more like this, just can regulate the equivalent inductance of primary winding, and not need tap.In addition, because secondary coil can be with some groups of capacitives (or perception) load, can obtain multiple different load progression easily by different combinations, as adopt controllable silicon to control, then can realize the load step-less adjustment, therefore, Current Regulation scope of the present utility model increases greatly.Because the utility model employing is the coil of insulation resin, be specially adapted to the fire-proof and explosion-proof place that requires height, no oiling such as city transformer station, underground substation, subway again.
