Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of iron core grounding structure of Triangular Three Dimensional Wound Core dry-type transformer.
Background technology
As everyone knows, three dimensional wound core transformer is a kind of Power-saving-type Power Transformer, it has creatively reformed laminated magnetic line structure and the three-phase layout of traditional power transformer, properties of product are more optimized, as three-phase magnetic circuit full symmetric, power savings significantly, noise reduces greatly, dispel the heat and overload capacity more by force, the feature such as compact conformation volume is little.
As shown in Figure 1, conventional stereo Wound iron-core transformer is by identical Winding iron core (i.e. the first iron core frame (1) of three physical dimensions, second iron core frame (2), and the 3rd iron core frame (6)) iron core arranged of the triangular solid that pieces together, due to the spatially triangular structure arrangement of three dimensional wound core transformer, in order to ensure reliable ground unshakable in one's determination, generally independently unshakable in one's determinationly draw a ground strip separately by three, namely the first iron core frame (1) is provided with ABC iron core and gathers ground strip (8), second iron core frame (2) is provided with the second iron core frame ground strip (3), 3rd iron core frame (6) is provided with the 3rd iron core frame ground strip (5), subsequently the second iron core frame ground strip (3) is connected wire (4) with the 3rd iron core frame ground strip (5) by BC iron core to connect, 3rd iron core frame ground strip (5) and ABC iron core are gathered ground strip (8) to be connected wire (7) to connect by CA iron core, namely closing three is one, and the ground strip through gathering is grounded through folder.This kind of earthing method is easy to cause connecting line short circuit to cause the problem of multipoint earthing unshakable in one's determination to occur.Although connection wire is carried out reinforced insulation by a lot of producer, aging along with what insulate, multipoint earthing problem unshakable in one's determination still frequently occurs.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of connection fastening, the iron core grounding structure of the Triangular Three Dimensional Wound Core dry-type transformer that security performance is good.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
An iron core grounding structure for Triangular Three Dimensional Wound Core dry-type transformer, described Triangular Three Dimensional Wound Core dry-type transformer comprises the first iron core frame (1), the second iron core frame (2) and the 3rd iron core frame (6) that are arranged in order distribution triangular in shape from beginning to end; Be separately installed with upper clamping piece and lower clamping piece at the two ends up and down of above-mentioned three iron core frames, described upper clamping piece is provided with earth stud; The outside of the first iron core frame (1) is provided with the first folder (9), and the outside of the second iron core frame (2) is provided with the second folder, and the outside of the 3rd iron core frame (6) is provided with the 3rd folder; Be welded with cold rolled silicon steel brace between described 3rd iron core frame (6) and the sidewall of the first iron core frame (1), between described 3rd iron core frame (6) and the sidewall of the second iron core frame (2), be welded with cold rolled silicon steel brace; Described first iron core frame (1) is provided with ABC iron core and gathers ground strip (8); Described ABC iron core gathers ground strip (8) and described earth stud close contact.
As optimal technical scheme, the utility model additionally uses following technical characteristic:
Further: the thickness of described cold rolled silicon steel brace is 0.3mm.
The advantage that the utility model has and good effect are:
Because the software conductor connecting structure between first iron core frame (1) of traditional triangle three-dimensional wound core dry type transformer, the second iron core frame (2) and the 3rd iron core frame (6) adopts cold rolled silicon steel brace Welding Structure to replace by the utility model, tie point unshakable in one's determination is transferred to sidewall (i.e. stem) unshakable in one's determination from the top of iron core simultaneously; Therefore, very securely the first iron core frame (1), the second iron core frame (2) and the 3rd iron core frame (6) can be linked together, form an equipotential entirety; Finally draw a ground strip (namely ABC iron core gathers ground strip (8)) on the first iron core frame (1) top, by the earth stud reliable ground on upper clamping piece.
