Description
Technical field
The utility model relates to a kind of transformer core web insulation systems, belong to technical field of transformer equipment.
Background technique
When transformer station high-voltage side bus, iron core and web are in electric field, and iron core need to be grounded respectively with web, between iron core and web
Creepage distance there was only the thickness of insulation board, if iron core is contacted with web, just will form multipoint earthing, generate floating potential and draw
Play discharge in insulation.Therefore, it needs to guarantee insulation distance between iron core and web, and passes through the reliable ground of iron core and web, protect
Demonstrate,prove the normal operation of transformer.
Utility model content
The utility model aim is to provide a kind of transformer core web insulation system, can increase between iron core and web
Creepage distance, guarantee the insulation distance between iron core and web, iron core avoided to contact with web, exist in solution background technique
The problem of.
The technical solution of the utility model is：
A kind of transformer core web insulation system includes iron core, web, core through screw rod, insulation board and screw hole, iron core
It is fixedly connected with web by multiple core through screw rod, insulation board is equipped between iron core and web, is divided on iron core, web and insulation board
The screw hole that She You not match with core through screw rod, the screw hole matched on the iron core and insulation board with core through screw rod are
Circular hole, the screw hole matched on the web with core through screw rod are bellmouth close to insulation board one end, and the other end is circular hole.
Angle [alpha] on the web close to the bellmouth of insulation board one end is 30-60 degree.
The both ends of the core through screw rod are respectively equipped with fastening nut.
The utility model has the beneficial effects that：By the bellmouth on web, climbing between iron core and web can be increased
Electrical distance guarantees the insulation distance between iron core and web, iron core is avoided to contact with web, forms multipoint earthing, generates suspension
Current potential causes discharge in insulation, influences the normal operation of transformer.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model web structure schematic diagram；
In figure：Iron core 1, web 2, core through screw rod 3, insulation board 4, creepage distance 5, screw hole 6.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1,2, a kind of transformer core web insulation system includes iron core 1, web 2, core through screw rod 3, insulation
Plate 4 and screw hole 6, iron core 1 and web 2 are fixedly connected by multiple core through screw rod 3, and insulation board is equipped between iron core 1 and web 2
4, the screw hole matched with core through screw rod 3, the iron core 1 and insulation board 4 are respectively equipped on iron core 1, web 2 and insulation board 4
The upper screw hole matched with core through screw rod 3 is circular hole, and the screw hole matched on the web 2 with core through screw rod 3 is close
4 one end of insulation board is bellmouth, and the other end is circular hole.
In the present embodiment, referring to attached drawing 1,2, screw hole on web 2 is bellmouth, bellmouth close to 4 one end of insulation board
Angle [alpha] be 30-60 degree, the other end is circular hole, and coniform hole and circular hole form through-hole, and bellmouth is big close to the aperture of insulation board 4
In the aperture of circular hole.
Creepage distance is the distance between two current-carrying parts along insulating materials surface.It, can by the bellmouth on web 2
To increase the creepage distance 5 between iron core 1 and web 2.
