Novel outdoor hollow dry-type reactor

Abstract

The invention relates to a novel outdoor hollow dry-typed reactor. The traditional outdoor hollow dry-typed reactor requires molding at one time during the manufacturing process and a cooling air duct is supported by a stay and requires overall stiffening, polishing and paint spraying after winding, thus causing difficult industrial production of the reactor in a manner of work pieces during the manufacturing process; as the stay covers the surface, the cooling condition is poor; the existence of the stay causes the cost to be increased; the quality of products excessively depends on the features of surface coatings, etc. In addition, in order to reduce the size of the occupied area, elliptic and rectangular structures can be adopted for windings. The novel outdoor hollow dry-typed reactor comprises a star frame, wherein, the star frame is connected with a winding (2) by a packing block (1); an upper star frame (17) and a lower star frame (8) are tensed and fixed by a glass fiber reinforced plastic body (3); the outer side of the winding (2) is provided with a envelopment (11) used for wrapping corona resistant and weather-proof thin film material; the winding can adopt multi-layer parallel connection form or continuous form or interleaved way or screw type or sectional form. The novel outdoor hollow dry-typed reactor is applied to electric power systems.

Description

Technical field: [0001] The invention relates to a novel outdoor hollow dry reactor. Background technique: [0002] Outdoor hollow dry-type reactor is a new generation of reactor products that appeared in the 1980s, such as figure 1 shown. It uses epoxy wrapping technology to completely seal the winding, and the wires are bonded to each other, which greatly increases the mechanical strength of the winding. At the same time, new weather-resistant materials are used to spray on the surface of the package, so that the product can meet the harsh conditions of outdoor operation. The air passages are formed by the struts between the envelopes, and the windings between the envelopes and the inner envelopes are usually connected in parallel to meet the requirements of capacity and heat dissipation. In order to meet the needs of reasonable distribution of current in each parallel branch, fractional turns are used to reduce the problem of circulating current between branches. In o...

Problems solved by technology

In addition, air-core reactors usually occupy the largest area and have the most serious external magnetic flux leakage, which is the main disadvantage of this type of reactor

[0004] Because the traditional outdoor hollow dry-type reactor must be formed at one time during the manufacturing process, the heat dissipation air channel is formed by the support of the stays, and it needs to be solidified, polished, and painted as a whole after winding, which causes the reactor to be very difficult in the manufacturing process. It is difficult to form workpieces for chemical industrial production. Due to the poor heat dissipation conditions caused by the covering of the surface by the stays, the existence of the stays causes the cost to increase, and the product quality is too dependent on the characteristics of the surface paint.
