The invention discloses a kind of reactor and pull bar thereof, belong to reactor manufacturing technology field.Reactor, including reactor winding and the upper and lower yoke clip piece being separately positioned on reactor winding upper/lower terminal, it is provided with pull bar between upper and lower yoke clip piece, described pull bar includes the drawhead forming pull bar both ends and forms the fiberglass rod of pull bar interlude, described drawhead has thread segment, and said two drawhead is respectively fixedly connected with on the two ends of fiberglass rod.The pull bar of the present invention is combined by drawhead and fiberglass rod and is formed, due to the material that fiberglass is a kind of light weight, intensity is high, price is low, therefore this pull bar is used to be possible not only to make upper and lower yoke clip piece to be strained and fixed reliably, can also reduce the overall weight of reactor, adaptability is the strongest.
Description
Technical field
The present invention relates to a kind of reactor and pull bar thereof, belong to reactor manufacturing technology field.
Background technology
Reactor is also inducer, and structure is divided into iron-core reactor and air reactor, causes inductance value to decline to reduce the saturated pcrmeability of iron-core reactor drastically to change, and general core limb is provided with multistage air gap.In order to make the iron-core reactor of band air gap form a firm entirety, the upper and lower yoke clip piece generally using pull bar to will be located in the upper and lower two ends of reactor winding is strained and fixed.The pull bar of the iron-core reactor of low capacity is the screw rod that stainless steel material is made, and the two ends of screw rod are through on upper and lower yoke clip piece respectively, are installed with the locking nut making screw rod be fixed between upper and lower yoke clip piece respectively at the two ends of screw rod.The pull bar of this screw-rod structure typically can meet the fixing requirement of the iron-core reactor of low capacity, and along with the increase of reactor capacity, the volume and weight of reactor also increases, and the demand being strained and fixed increases the most therewith, and therefore diameter and the length of screw rod should increase accordingly.When the capacity of reactor is the biggest, the size of corresponding screw rod is the biggest, such as capacity is that the reactor of 8000kvar should use a diameter of 40mm, the screw rod of a length of 2m, but this large-sized screw rod is commercially difficult to buy, and the weight of this screw rod is big, price is high, the overall weight causing reactor is big, cost is high.
Summary of the invention
It is an object of the invention to provide a kind of low cost, be applicable to the pull bar of high-capacity reactor.Meanwhile, the present invention also provides for a kind of reactor using this pull bar.
For achieving the above object, the reactor of the present invention adopts the following technical scheme that a kind of reactor, including reactor winding and the upper and lower yoke clip piece being separately positioned on reactor winding upper/lower terminal, it is provided with pull bar between upper and lower yoke clip piece, described pull bar includes the drawhead forming pull bar both ends and forms the fiberglass rod of pull bar interlude, described drawhead has thread segment, and said two drawhead is respectively fixedly connected with on the two ends of fiberglass rod.
Described drawhead is a screw rod.
Described drawhead includes the screw rod that two parallel interval are arranged, and is fixed with connector between two screw rods, and two screw rods and connector form U-shaped structure, and the two ends of described fiberglass rod are fixing with corresponding connector respectively to be connected.
Described fiberglass rod by being wrapped between two connectors, the organdy of dipped epoxy resin is formed through hot setting.
The surface that described connector is wound around contact for organdy is arcwall face.
The reactor pull bar of the present invention adopts the following technical scheme that a kind of reactor pull bar, it drawhead including forming pull bar both ends and the fiberglass rod of formation pull bar interlude, described drawhead has thread segment, and said two drawhead is respectively fixedly connected with on the two ends of fiberglass rod.
Described drawhead is a screw rod.
Described drawhead includes the screw rod that two parallel interval are arranged, and is fixed with connector between two screw rods, and two screw rods and connector form U-shaped structure, and the two ends of described fiberglass rod are fixing with corresponding connector respectively to be connected.
Described fiberglass rod by being wrapped between two connectors, the organdy of dipped epoxy resin is formed through hot setting.
The surface that described connector is wound around contact for organdy is arcwall face.
Pull bar in use, is fixed between upper and lower yoke clip piece by the pull bar of the present invention by spinning locking nut on drawhead thread segment, so that upper and lower yoke clip piece is strained and fixed.The pull bar of the present invention is combined by drawhead and fiberglass rod and is formed, due to the material that fiberglass is a kind of light weight, intensity is high, price is low, therefore this pull bar is used to be possible not only to make upper and lower yoke clip piece to be strained and fixed reliably, moreover it is possible to reduce the overall weight of reactor.Owing to fiberglass has good insulating properties, between fiberglass rod and reactor winding, need not arrange certain insulation distance, therefore can reduce the volume of reactor, thus reduce the weight of reactor further.The thickness of fiberglass rod and length are the size of the reactor according to different size and capacity is designed, and therefore the pull bar adaptability of the present invention is the strongest.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of reactor of the present invention；
Fig. 2 is the structural representation of the pull bar in Fig. 1；
Fig. 3 is the enlarged drawing of the end of pull bar in Fig. 2.
Detailed description of the invention
The structure of a kind of embodiment of reactor of the present invention is as shown in Figure 1 to Figure 3, the reactor of the present embodiment includes reactor winding 3 and is separately positioned on the upper and lower yoke clip piece 1,4 of reactor winding 3 upper/lower terminal, it is provided with pull bar 2 between upper and lower yoke clip piece 1,4, pull bar 2 includes the drawhead 5 forming pull bar both ends and forms the fiberglass rod 6 of pull bar interlude, and two drawheads 5 are respectively fixedly connected with on the two ends of fiberglass rod 6.The drawhead 5 of the present embodiment includes the screw rod 7 that two parallel interval are arranged, and is fixed with connector 8 between two screw rods 7, and two screw rods 7 and connector 8 form U-shaped structure, and the two ends of fiberglass rod 6 are respectively fixedly connected with on corresponding connector 8.The fiberglass rod of the present embodiment by being wrapped between two connectors, the organdy of dipped epoxy resin is formed through hot setting, the surface that connector is wound around for organdy is arcwall face.When making fiberglass rod, the length of fiberglass rod is determined by the distance of two drawheads, and the thickness of fiberglass rod is determined by the number of plies of the organdy being wound around.
Pull bar when mounted, is fixed between upper and lower yoke clip piece by the present embodiment by spinning locking nut on screw rod.Due to the material that fiberglass is a kind of light weight, intensity is high, price is low, therefore the pull bar of the present embodiment is possible not only to make upper and lower yoke clip piece to be strained and fixed reliably, moreover it is possible to reduce the overall weight of reactor.Owing to fiberglass has good insulating properties, between fiberglass rod and reactor winding, need not arrange certain insulation distance, therefore can reduce the volume of reactor, thus reduce the weight of reactor further.
In the other embodiments of reactor of the present invention, fiberglass rod can also be made in advance by the method that hands is stuck with paste, and then fiberglass rod is fixed together with drawhead also by threaded mode；The drawhead of the present invention can also be made up of a screw rod.
A kind of embodiment of reactor pull bar of the present invention is identical with the structure of pull bar in the embodiment of reactor of the present invention, and here is omitted.
