Description
Technical field
The utility model relates to a kind of reactor and pull bar thereof, belongs to reactor manufacturing technology field.
Background technology
Reactor is also inductor, is divided into iron-core reactor and air core reactor in structure, causes inductance value to decline in order to reduce the saturated magnetic permeability of iron-core reactor sharply to change, and general core limb is provided with multistage air gap.In order to make the iron-core reactor with air gap form a firmly entirety, conventionally adopt pull bar that the upper and lower yoke clip piece that is positioned at 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 respectively on upper and lower yoke clip piece, is installed with respectively and makes screw rod be fixed on the locking nut between upper and lower yoke clip piece at the two ends of screw rod.The pull bar of this screw-rod structure generally can meet the fixing requirement of the iron-core reactor of low capacity, along with the increase of reactor capacity, the volume and weight of reactor also increases, and the demand being strained and fixed also increases thereupon, and therefore the diameter of screw rod and length should corresponding increases.In the time that the capacity of reactor is very large, the size of corresponding screw rod is also very large, it is the screw rod that 40mm, length are 2m that the reactor that for example capacity is 8000kvar should adopt diameter, but this large-sized screw rod is difficult to buy on market, and the weight of this screw rod is large, price is high, cause the overall weight of reactor large, cost is high.
Summary of the invention
The purpose of this utility model is the pull bar that a kind of low cost is provided, is applicable to high-capacity reactor.Meanwhile, the utility model also provides a kind of reactor that uses this pull bar.
For achieving the above object, reactor of the present utility model adopts following technical scheme: reactor, comprise reactor winding and the upper and lower yoke clip piece that is separately positioned on reactor winding upper/lower terminal, between upper and lower yoke clip piece, be provided with pull bar, described pull bar comprises the drawhead that forms pull bar both ends and the fiberglass rod that forms pull bar interlude, described drawhead has thread segment, and described two drawheads are fixedly connected on respectively on the two ends of fiberglass rod.
Described drawhead is a screw rod.
Described drawhead comprises the screw rod that two parallel interval arrange, and between two screw rods, is fixed with connector, and two screw rods and connector form U-shaped structure, and the two ends of described fiberglass rod are fixedly connected with corresponding connector respectively.
Described fiberglass rod by being wrapped between two connectors, soaked that the organdy of epoxy resin forms through hot setting.
The surface that described connector is wound around contact for organdy is arcwall face.
Reactor pull bar of the present utility model adopts following technical scheme: reactor pull bar, it comprises the drawhead that forms pull bar both ends and the fiberglass rod that forms pull bar interlude, described drawhead has thread segment, and described two drawheads are fixedly connected on respectively on the two ends of fiberglass rod.
Described drawhead is a screw rod.
Described drawhead comprises the screw rod that two parallel interval arrange, and between two screw rods, is fixed with connector, and two screw rods and connector form U-shaped structure, and the two ends of described fiberglass rod are fixedly connected with corresponding connector respectively.
Described fiberglass rod by being wrapped between two connectors, soaked that the organdy of epoxy resin forms through hot setting.
The surface that described connector is wound around contact for organdy is arcwall face.
In use, the locking nut by spinning on drawhead thread segment is fixed on pull bar between upper and lower yoke clip piece pull bar of the present utility model, thereby upper and lower yoke clip piece is strained and fixed.Pull bar of the present utility model is combined to form by drawhead and fiberglass rod, because fiberglass is the material that a kind of quality is light, intensity is high, price is low, therefore use this pull bar not only can make upper and lower yoke clip piece be strained and fixed reliably, can also reduce the overall weight of reactor.Because fiberglass has good insulation property, between fiberglass rod and reactor winding, do not need to arrange certain insulation distance, therefore can reduce the volume of reactor, thereby further reduce the weight of reactor.The thickness of fiberglass rod and length are to design according to the size of the reactor of different size and capacity, and therefore pull bar adaptability of the present utility model is very strong.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model reactor;
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.
Embodiment
The structure of a kind of embodiment of the utility model reactor as shown in Figure 1 to Figure 3, the reactor of the present embodiment comprises reactor winding 3 and is separately positioned on the upper and lower yoke clip piece 1,4 of reactor winding 3 upper/lower terminals, between upper and lower yoke clip piece 1,4, be provided with pull bar 2, pull bar 2 comprises that 6, two drawheads 5 of fiberglass rod that form the drawhead 5 at pull bar both ends and form pull bar interlude are fixedly connected on respectively on the two ends of fiberglass rod 6.The drawhead 5 of the present embodiment comprises and between 7, two screw rods 7 of screw rod that two parallel interval arrange, is fixed with 8, two screw rods 7 of connector and connector 8 forms U-shaped structure, and the two ends of fiberglass rod 6 are fixedly connected on respectively on corresponding connector 8.The fiberglass rod of the present embodiment by being wrapped between two connectors, soaked that the organdy of epoxy resin forms through hot setting, the surface that connector is wound around for organdy is arcwall face.Making when fiberglass rod, the length of fiberglass rod determines 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.
When mounted, the locking nut by spinning on screw rod is fixed on pull bar between upper and lower yoke clip piece the present embodiment.Because fiberglass is the material that a kind of quality is light, intensity is high, price is low, therefore the pull bar of the present embodiment not only can make upper and lower yoke clip piece be strained and fixed reliably, can also reduce the overall weight of reactor.Because fiberglass has good insulation property, between fiberglass rod and reactor winding, do not need to arrange certain insulation distance, therefore can reduce the volume of reactor, thereby further reduce the weight of reactor.
In other embodiment of the utility model reactor, fiberglass rod also can be made in advance by the method that hand is stuck with paste, and mode and drawhead that then fiberglass rod is also threaded connection are fixed together; Drawhead of the present utility model also can be made up of a screw rod.
A kind of embodiment of the utility model reactor pull bar is identical with the structure of pull bar in the embodiment of the utility model reactor, repeats no more herein.
