Abstract
The utility model relates to a transformer subassembly structure, especially a dry -type distribution transformer electrical connection terminal protection casing. This structure includes an iron core, and the coiling has high voltage winding and low voltage winding on the iron core, is equipped with a binding post mounting surface on high voltage winding's side, is equipped with a set of shunting gear binding post on binding post mounting surface, shunting gear binding post around be equipped with a protection casing, completely cut off binding post with outside after the protection casing is installed in binding post mounting surface on. The utility model discloses a dry -type distribution transformer electrical connection terminal protection casing has the high voltage through with winding connecting terminal setting protection type structure because the wiring is held when the operation to the effectual emergence of taking precautions against the electric shock accidents, also effectual the strick precaution like the dust, dirts etc. Are to live part's pollution and corruption, under the prerequisite of well being protected, have improved the life of product effectively, the user use cost of furthest's reduction.
Description
Technical field
This utility model relates to a kind of transformer device structure, especially a kind of dry-type distribution transformer electrical terminals protective cover.
Background technology
Dry-type distribution transformer, also referred to as dry-type transformer, refers to the transformer type that iron core and winding are not immersed in insulating oil, the occasion such as the transformator illumination of the type, building, airport, harbour and all types of numerically controlled processing equipments.The basic structure of existing dry-type distribution transformer includes an iron core, is wound with winding on iron core, and the upper and lower of iron core is provided with fastening folder and the wiring position being connected with winding.Wiring place at existing dry-type distribution transformer, in order to avoid electrical terminals and extraneous contact, generally after wire rod is connected with electrical terminals, electrical connection place is closed by sealing at electrical terminals place, it is to the effect of insulation, and this mode exists two weak points.
1, dry-type distribution transformer is large-scale converting equipment, and its operating temperature is higher and uses environment comparatively uncertain, in some cases, sealing can dry and cracked peeling, lose insulating effect；
2, often there is more electrical terminals on an equipment, each electrical terminals line carries out sealing operation later, improves the complexity of operation, reduces efficiency.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of stability that can keep and using, and reduces the kind dry-type distribution transformer electrical terminals protective cover of operation easier.
To achieve these goals, this utility model adopts the following technical scheme that
This structure includes an iron core, iron core is wound with high pressure winding and low pressure winding, it is improved by: be provided with a binding post mounting plane on the side of high pressure winding, binding post mounting plane is provided with one group of tapping gear binding post, described tapping gear binding post is provided around a protective cover, and protective cover is installed on binding post mounting plane later by binding post and external environment.
Preferably, at least provided with two protective cover fixing holes by described tapping gear binding post, described protective cover is fixed in protective cover fixing hole by insulated bolt.
Preferably, two described protective cover fixing holes are angularly disposed.
Preferably, the height of described protective cover fixing hole and size are equal to height and the size of tapping gear binding post.
Preferably, described binding post mounting plane is provided with groove, and the edge of described protective cover embeds and is installed in groove.
Preferably, described protective cover adopts insulation transparent material to be pressed into rectangular box lid.
Owing to have employed said structure; dry-type distribution transformer electrical terminals protective cover of the present utility model is by arranging protection type structure by winding connection terminal; due to terminals operationally all with high voltage; thus effectively having taken precautions against the generation of electric shock accidents; also effectively having taken precautions against such as dust, dirt etc. is to the pollution of live part and corrosion, under the premise obtaining good protection; it is effectively improved the service life of product, the customer using cost reduced to greatest extent.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of this utility model embodiment；
Fig. 2 is the side structure schematic diagram of this utility model embodiment.
Detailed description of the invention
As shown in Figure 1-2, dry-type distribution transformer electrical terminals protective cover of the present utility model includes an iron core 1, iron core 1 is wound with high pressure winding 2 and low pressure winding 3, the side of high pressure winding 2 is provided with a binding post mounting plane 4, binding post mounting plane 4 is provided with one group of tapping gear binding post 5, described tapping gear binding post 5 is provided around a protective cover 6, and protective cover 6 is installed on binding post mounting plane later by binding post and external environment.
In the present embodiment, described tapping gear binding post 5 is other at least provided with two protective cover fixing holes 7, and described protective cover 6 is fixed in protective cover fixing hole 7 by insulated bolt.
In the present embodiment, two described protective cover fixing holes 7 are angularly disposed.
In the present embodiment, the height of described protective cover fixing hole 7 and size are equal to height and the size of tapping gear binding post 5.
During for the ease of installing, location, simultaneously works as better seal effect, and in the present embodiment, described binding post mounting plane is provided with groove 8, and the edge of described protective cover 6 embeds and is installed in groove 8.
In the present embodiment, described protective cover 6 adopts insulation transparent material to be pressed into rectangular box lid.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
