Abstract
The utility model relates to a current mutual inducer for the line outlet end of a transformer. The current mutual inducer comprises an integral structure formed by epoxy resin-vacuum pouring of an iron core, a secondary winding and a secondary wiring terminal. The integral structure further comprises a mounting base plate which is directly shaped with integral structure at one time; the integral structure takes the shape of a square cylinder; the section of a primary busbar wire outlet is rectangular; a mounting hole on the mounting base plate is a long through hole; the four corners of the square cylinder-shaped structure are circular; and the four corners of the rectangular busbar wire outlet are transitional circular corners. The current mutual inducer has the characteristics of small size, standardization, high mechanical intensity, aging resistance, long service life, vibration and impact resistance, convenient installation, etc.
Description
Technical field
The utility model relates to electric power system high-tension measurement and protective device, specifically a kind of transformer leading-out terminal current transformer.
Background technology
Transformer leading-out terminal current transformer is power plant excitation transformer in the electric power system, the rectifier transformer leading-out terminal equipment as current measurement, relaying protection.There are a lot of problems in existing transformer leading-out terminal current transformer, mainly show following several aspect: one, small product size is big, normalisation coefft is low, mainly use the conventional instrument transformer of electric power system, busbar line outlet and transformer outlet row can not be rationally supporting, have a lot of waste of material phenomenons; Two, mechanical strength is low, and the insulation form is mainly plastic casing, and is often broken when installing and using, and needs protection especially; Three, ageing-resistant degree is poor, and useful life is low, is subjected to the high influence of normal runtime environment temperature, and the product main material is aging in advance, greatly reduces the useful life of product; Four, anti-mechanical oscillation impact capacity is poor, because the vibration of the normal operation of supporting transformer or the vibration effect of running environment, the fixed form of product can not satisfy fully uses needs, and fixing loosening phenomenon often takes place, and needs the attendant often to safeguard.Above problems are the main difficult problem of puzzlement transformer production producer and the hidden danger of complete set of equipments safe operation, and the design of the mutual device of transformer leading-out terminal electric current must be innovated and update.
The utility model content
At above shortcomings part in the prior art, the technical problems to be solved in the utility model provides the transformer leading-out terminal current transformer that a kind of volume is little, normalisation coefft is high, mechanical strength is high, ageing-resistant.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The utility model relates to a kind of transformer leading-out terminal current transformer, comprising by iron core, secondary winding and secondary connection terminal adopts the epoxide resin vacuum cast to form integral structure, described integral structure also comprises the installation base plate, with the direct once-forming of above-mentioned integral structure; Described integral structure is the square tube shape, and one time busbar line outlet cross sectional shape is a rectangle.
Installing hole on the described installation base plate is elongated hole; Four jiaos of square tube shape structure is fillet; Rectangle bus mouth is the knuckle form for four jiaos.
The utlity model has following beneficial effect and advantage:
1. little, the standardization of volume: the utility model adopts the epoxide resin vacuum cast and is integral square tube formula structure, volume is little in light weight, the once female line outlet of product can be made the standardization slot of different size as required, realize standard interface with transformer leading-out terminal busbar, used in the past the conventional instrument transformer of larger volume electric power system and needn't resemble, busbar line outlet and transformer outlet row can not be rationally supporting, have a lot of waste of material phenomenons;
2. mechanical strength height, ageing-resistant, long service life: integral structure is that the epoxide resin vacuum cast forms, and product is not subjected to the temperature effect of environment, has higher mechanical strength and heatproof ageing resistace, longer service life.
3. vibration and shock resistant, easy for installation: because adopted installation base plate and the direct once-forming of integral structure, make product have vibration and shock resistant performance preferably, and base plate is installed is adopted the installing hole of elongated hole shape to guarantee that product is field erected convenient and swift.

Embodiment
Shown in Fig. 1～4, the utlity model has inner core 1, secondary winding 2 and secondary connection terminal 3 and adopt the epoxide resin vacuum cast to form integral structure, this integral structure also comprises, installs base plate 4, with the direct once-forming of above-mentioned integral structure; Whole integral structure is the square tube shape of a horizontal positioned, and inner envelope is put secondary winding 2; One time busbar line outlet 5 cross sectional shapes are rectangle; The mistake ferry of a bus was according to the difference of transformer leading-out terminal size of current when 5 conducts of busbar line outlet of inner chamber were installed and used, and its rectangle can adopt different sizes;
Installation base plate 4 of the present utility model casts directly over integral structure, makes itself and overall structure fluid-tight engagement, has vibration and shock resistant function; The installing hole of installing on the base plate 4 is elongated hole 6, make things convenient for transformer flexible installation;
The utility model square tube shape structure has very big fillet 7 for four jiaos, makes to the utlity model has strong mechanical strength and smaller volume.
Rectangle bus mouth is a knuckle form 8 for four jiaos, makes to the utlity model has strong mechanical strength, and is convenient to smooth installation with transformer rectangle busbar.
The utility model transformer leading-out terminal current transformer is a kind of new product that designs according to national standard fully; adopt the epoxide resin vacuum cast to form; employing rolls iron core; utilize electromagnetic conversion principle and Electric Field Distribution principle; make the secondary current situation of change of reflected measurement primary current exactly; be transferred to secondary measurement and control device, use, be widely used in the electric power system device for transformer as current measurement and relaying protection.
