Description
Technical field
The utility model is related to a kind of transformer core core through screw rod insulation systems, belong to technical field of transformer equipment.
Background technology
Iron core core through screw rod outsourcing insulation generally use wrinkle quires packet, when being installed across core lamination stack trepanning, wrinkle
Paper is easily damaged and can not find, such as exposed core through screw rod is contacted with core lamination stack or core lamination stack pass through with folder it is exposed
Core through screw rod short circuit, will produce the insulation such as short circuit or multipoint earthing of iron core hidden danger between lamination piece, it is serious iron core to be caused to send out
Raw spark discharge, hot-spot, seriously affect the normal safe operation of transformer.
Utility model content
The utility model aim is to provide a kind of transformer core core through screw rod insulation system, ensures insulation effect, avoids
Core through screw rod is contacted with core lamination stack, and the insulation hidden danger such as short circuit or multipoint earthing of iron core between lamination occurs, solves in background technology
There are the problem of.
The technical solution of the utility model is：
A kind of transformer core core through screw rod insulation system, including iron core, folder, core through screw rod, profiled insulation pipe, insulation
Washer and fixing nut, are fixedly connected between iron core and folder by core through screw rod, and core through screw rod both ends are equipped with fixing nut, wear
Heart screw rod is located in profiled insulation pipe, and the both ends of profiled insulation pipe are respectively equipped with insulating washer, and the insulating washer passes through punching
Fixing nut on screw rod is fixed on folder；The profiled insulation pipe penetrates in insulating washer along its length, profiled insulation
Pipe and the fixed connection of insulating washer.
The internal diameter of the profiled insulation pipe is matched with the outer diameter of core through screw rod.
The utility model has the beneficial effects that：Pass through profiled insulation pipe on the outside of core through screw rod and profiled insulation pipe both ends
Insulating washer ensures the insulation effect of core through screw rod, core through screw rod is avoided to be contacted with core lamination stack and folder, and it is folded to eliminate generation
The accident potential of short circuit or multipoint earthing of iron core between piece.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model insulating tube structure schematic diagram.
In figure：Iron core 1, folder 2, core through screw rod 3, profiled insulation pipe 4, insulating washer 5, fixing nut 6.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1,2, a kind of transformer core core through screw rod insulation system, including iron core 1, folder 2, core through screw rod 3,
Profiled insulation pipe 4, insulating washer 5 and fixing nut 6, are fixedly connected between iron core 1 and folder 2 by core through screw rod 3, punching spiral shell
3 both ends of bar are equipped with fixing nut 6, and core through screw rod 3 is located in profiled insulation pipe 4, and the both ends of profiled insulation pipe 4 are respectively equipped with insulation
Washer 5, the insulating washer 5 are fixed on by the fixing nut 6 on core through screw rod 3 on folder 2.
In the present embodiment, 4 surface requirements of profiled insulation pipe are smooth, the trepanning on profiled insulation pipe 4 and core lamination stack it
Between there are certain intervals, it is ensured that when across core lamination stack trepanning stand intact.4 length direction of profiled insulation pipe penetrates insulation
Washer 5, and the necessary lap of splice is kept, ensure insulation distance enough between iron core 1 and folder 2.Insulating washer 5 is located at folder
The outside of part 2, insulating washer 5 are fixed on by the fixing nut 6 on core through screw rod 3 on folder 2.
