Abstract
The utility model relates to a CT leading-out terminal board with large creepage distance and small diameter for a large-sized power transformer, a commutator transformer, a reactor and the like, comprising a terminal board and a conductive rod which are integrated by pressure injection and stiffening. The two sides of the terminal board are provided with a lug boss. An electric field separating rib is arranged among the terminals of the side contacting with air. Because the two sides of the terminal board are provided with the lug boss, the intension of the terminal board is increased; a lead wire can be distributed evenly; and the insulation distance can be ensured. The electric field separating rib can separate the electric field and increase the creepage distance. Therefore, the distance of adjacent terminals is very small; the design requirement of multiple terminals and small diameter can be met; and the product cost can be reduced at the same time.
Description
Technical field
The utility model relates to a kind of large distance minor diameter CT exit daughter board that is used for large-scale power transformer, rectifier transformer, reactor etc.
Background technology
CT exit daughter board all utilizes mould to make at present.In mould, adopt the mixture of epoxy resin, fixative, silicon powder that copper conducting rod high temperature is fixed, curing process has just been made CT exit daughter board after the warp again.Requiring between the terminal on the CT exit daughter board has certain insulation distance, so the diameter of conducting rod radical terminal board how is big.The big terminal board of diameter is except the cost height, also brings difficulty for aspects such as the optimal design of transformer such as aesthetic property.
Summary of the invention
The purpose of this utility model provides and a kind ofly can satisfy that the conducting rod radical is many, diameter is little, creepage distance is big and the CT exit daughter board of easy-to-connect.
The utility model comprises terminal board, conducting rod, and conducting rod and terminal board are to solidify and be integral through pressure injection, and the terminal board both sides are provided with boss, and are equipped with the electric field isolation muscle between each terminal of air contact side.
Because the terminal board both sides are provided with boss, the even distribution that can increase the intensity of terminal board and help going between can guarantee insulation distance, and the electric field isolation muscle can cut off electric field and increase creepage distance.Therefore distance is very little between terminals of adjacent, can satisfy the designing requirement of multiterminal, minor diameter, has reduced product cost simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A cutaway view;
Fig. 3 is an electric field isolation muscle cutaway view.
1 is terminal board among the figure, and 2 is conducting rod, and 3 is boss, and 4 is the electric field isolation muscle.
Embodiment
As shown in the figure, the utility model comprises CT exit daughter board, conducting rod, terminal board 1 is to do by the fix agent, silicon powder of indoor epoxy resin, modified anhydride that filler, polyethers are made flexibilizer, benzyl dimethylamine adds mill base as promoter, press indoor epoxy resin 100: fixative 100: filler 330: flexibilizer 1.7: promoter 0.14: the proportioning of mill base 1.3, through APG technology, form with many copper conducting rod 2 pressure injections curing, the end of conducting rod is the wiring exit.The terminal board of making to increase the intensity of terminal board, is equipped with electric field isolation muscle 4 with the air contact side and be immersed in that side is equipped with boss 3 in the oil between the terminal of this terminal board and air contact side, can cut off the creepage distance between electric field and increase terminal.
Claims (1)
1, a kind of large distance minor diameter CT exit daughter board, comprise CT exit daughter board (1), conducting rod (2), it is characterized in that this terminal board (1) and air contact side and be immersed in that side is equipped with boss (3) in the oil, and be provided with electric field isolation muscle (4) between the terminal of air contact side.
