Description
The present invention relates to be used for the air-core reactor of electrical power transmission system, the present invention especially describes a kind of improved tap reactor that is used for filter circuit, and at this, what often need is the on-the-spot inductance value of adjusting reactor.The invention still further relates to a kind of method of making air-core reactor, and a kind of rigid cylinder formula air-core reactor, it has the open spiral winding that is partially submerged into, and this winding is fixedly secured on the structural sleeve of rigidity.
The reactor of electric power system often combines use with capacitor and resistor, is used to finish the filter function in the electric power system.For example, they are used to pouring in of control capacitor group electric current and gush out, prevent to enter in the electrical network by the interfering frequency that rectification and Inverter Station produce, or the like.In many such application, know desired inductance value on the reactor definitely, guarantee that the filter that produces is transformed into correct frequency or frequency band is impossible.This is because many unknown numbers were arranged before actual installation is finished.Be used for guaranteeing that the general game that filter is transformed into correct frequency or frequency band is to dispose reactor with specific tap series, above-mentioned tap is set on the fixing position.
The example of known tap air-core reactor is the proprietary former obligee's of the present invention Canadian Patent 1,065,028 with reference to what announced on October 23rd, 1979 with Trench ElectricLimited.The tap reactor that this patents has a primary air core reactor part, this part is basically with this everyone early stage United States Patent (USP) 3,264,590 technology constitutes, above-mentioned United States Patent (USP) was announced on August 2nd, 1966, this structure is depicted among Figure 11, and wherein concentric coil windings is embedded in the resin material of a reinforcing.Every end in the end opposite of coil has a support, thereby allows to exist the local number of turn and be used for the winding that is connected in parallel.Each support is a rigid parts, and it has a maincenter, and this maincenter has from its radially outer a plurality of arms.Arm and maincenter are by electric conducting material or be installed in whole manufacturing of electric conducting material on the rigid structural member.The axle of maincenter is set on the axle of coil unit.The tap of reactor partly is pancake naked spirality winding, and this winding is by bottom support and be positioned in its downside.People can be connected in series it to naked spiral tapping on different positions with main coil.
The another kind of form of tap reactor is depicted in and is entitled as on the brochure of Trench Electric Applicance Co., Ltd of report by name 100-5E that be September nineteen eighty-three " dry-type air-core reactor " issuing date.Described a columnar reactor in Fig. 5, this reactor has the tap on the fixed position of passing insulating material, and insulating material comprises the conductor that is embedded in wherein.This report has also been introduced the tap scope of this reactor, and this scope is covered by the cylindrical serial connection of single encapsulation of bar or cable conductor.
The air-core reactor of high current capacity has many different application in electrical power transmission system, should be used for saying for these, requirement the most basic is that they must have the ability to bear very high machinery and thermal stress, above-mentioned stress is to be added on the reactor as the result that the superelevation electric current flows through, and this very high electric current occurs under the short-circuit conditions.In order to bear this point, reactor must have high structural stability, and coil-conductor will firmly fix in place.Coil windings must not have deformation in addition, is because manufacturing technology causes certainly on this part.
An object of the present invention is to provide a kind of air-core reactor with tap rigid element, this tap partly is used for an inductance and incrementally is adjusted to exact value.
Another purpose provides a kind of adjustable tap reactor, and this reactor can be regulated at the scene and reach desired inductance exact value.
Further purpose of the present invention provides a kind of reactor, this reactor has a rod-shaped conductors, it is local at least be embedded in the open spirality winding and secure lock in place, this reactor is so designed, thereby simplified manufacturing technique is convenient to produce in batches.
Consistent with above-mentioned purpose, according to an aspect of the present invention, provide a kind of air-core reactor at this, this reactor comprises the sleeve of the rigidity structure of being made by electrical insulating material; With the coil windings that is made of conductor of open spirality winding configuration, this winding is set on the outer surface of described sleeve, and described conductor has selected cross-sectional shape, and this profile has the wedge shape foundation of adjacent described sleeve; The insulation gap spare that between the adjacent turn of winding, has preset width, each turn-to-turn of winding keeps identical fixedly predetermined space relation on the whole length of winding; And at the locator material that radially is provided with, this material provides the partially filled at least filling to recess between the adjacent turn, and described filling the conductor locks in place, and provides the assembly of a rigidity with the described wedge shape foundation of conductor whereby.On preferred configuration, the outer end portion of conductor is exposed.In this external preferred configuration, distance piece is the bar that twines simultaneously with conductor, and the even interval of conductor turns is provided in manufacture process.Outstanding on this spacer bar part below conductor, thus provide adjacent turn conductor each other correct means in place.In one embodiment, this correct means in place comprise side recessed (being also referred to as the base groove after this), the opposite edges of the spacer bar on the recessed admittance adjacent conductor of the side circle on one of two bottom lengths direction edges of conductor.In another embodiment, spacer bar is actual "T"-shaped on the cross section, and the part of spacer bar is outwards protruded between two adjacent turn whereby.
Can comprise the spiral winding reactor of individual layer that has the tap that is installed in a close end by tap reactor provided by the invention, perhaps they can comprise two concentric spiral winding reactors that are connected in series, and outer field one has tap altogether.In each case, the tap part is made by aluminium conductor, and this aluminium conductor has special profile, and this profile has intensity and encapsulation easily, and reserves exposed outer end face, makes tap easily to be installed in required part.This tap can for good and all be fixed or install movably.
Reactor construction cost of the present invention is cheap, and possesses such structure, promptly utilize in the required local required tap of installing, might accurately obtain the central required inductance value of any practical application, rather than obtain by the selection from many fixed taps, fixed taps only provides rough correct result.
Advantage of the present invention is to allow tap is placed in Anywhere, even move at the scene or adjust.So in addition structure makes reactor of the present invention very firm, and simultaneously for being relatively economical with high-quality construction.
