Abstract
The closed breakout box of a kind of dry-type transformer of the utility model.This comprises the transformation winding being arranged side by side, described transformation winding outside is socketed with insulation shell, described insulation shell arranged outside is useful on the breakout box of wiring, described breakout box comprises cylindrical housings, bottom in the inside of cylindrical housings is provided with some binding posts along circumference, between binding post, be provided with the creepage ridge of protruding insulation, at the end face of cylindrical housings, be provided with insulation lid.Binding post is enclosed in columniform terminal box, has reduced the length dimension that binding post takies, and has increased the coil high pressure head and the tail joint terminal of dry-type transformer and the safe distance between binding post.
Description
Technical field
The utility model relates to a kind of dry-type transformer, relates in particular to the closed breakout box of a kind of dry-type transformer.
Background technology
Epoxy resin-insulated dry type transformer is the important electrical in power network, and in order to meet voltage ripple of power network requirement, transformer must, with the binding post of adjustable tapping gear, generally be positioned at transformer coil middle part.The dry-type transformer of special low capacity is because loop length size is less, distance between the first joint terminal of high pressure and high pressure tail joint terminal is less, binding post, the distance between high pressure connecting lead wire of coil high pressure head and the tail joint terminal (A, B, C and X, Y, Z) and tap are too near, and can not meet relevant criterion acceptance requirement.
How to make having enough safe distances between the coil high pressure initial and end joint terminal of dry-type transformer of special low capacity and binding post is those skilled in the art's problem demanding prompt solution always.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provide between a kind of coil high pressure initial and end joint terminal that makes dry-type transformer and binding post, have enough safe distances the closed breakout box of dry-type transformer.
For achieving the above object, the technical scheme that the closed breakout box of the utility model dry-type transformer adopts is:
The closed breakout box of a kind of dry-type transformer, comprise the transformation winding being arranged side by side, described transformation winding outside is socketed with insulation shell, described insulation shell arranged outside is useful on the breakout box of wiring, described breakout box comprises cylindrical housings, bottom in the inside of cylindrical housings is provided with some binding posts along circumference, is provided with the creepage ridge of protruding insulation between binding post, at the end face of cylindrical housings, is provided with insulation lid.Binding post is enclosed in columniform terminal box, has reduced the length dimension that binding post takies, and has increased the coil high pressure head and the tail joint terminal of dry-type transformer and the safe distance between binding post.
Cylindrical housings and the insulation shell of described terminal box are wholely set.The cylindrical housings of terminal box and the moulding of insulation shell integration mold, improved insulation effect when having reduced production cost.
The side mark of described binding post has Arabic sequence number, and the font degree of depth of Arabic sequence number is 1mm.Binding post embedded with cylindrical housings bottom, binding post side mark has Arabic sequence number to be convenient to workman's gear according to actual needs to carry out wiring.
Described insulation lid is transparent insulation lid.Transparent lid is convenient to observe the wiring situation of binding post, easy access.
The utility model compared with prior art, has the following advantages:
Binding post is enclosed in columniform terminal box, reduced the length dimension that binding post takies, the dry-type transformer that is suitable for low capacity, the coil high pressure head and the tail joint terminal of dry-type transformer and the safe distance between binding post have been increased, insulation lid can be enclosed in binding post in terminal box, further guaranteed binding post fail safe, the creepage ridge arranging between binding post can increase the creepage distance between binding post, meets safe requirement.The closed breakout box of dry-type transformer of the present utility model is simple in structure, compact, security performance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model dry-type transformer.
Fig. 2 is the schematic diagram of the closed breakout box of dry-type transformer.
