Abstract
The utility model relates to a novel dry type transformer which is provided with a winding coil structure. The novel dry type transformer comprises an iron core which is provided with at least a group of a high-voltage winding and a low-voltage winding. At least one of each group of the high-voltage winding and the low-voltage winding is divided into two sections, each section is provided with a head end and a tail end, an insulation structure is arranged between the sections, and the tail ends of the upper side sections and the head ends of the lower side sections of two adjacent sections are guided out through binding posts and are connected through lug plates. According to the technical scheme, the specific position of short circuiting can be judged during circuit shorting, only a fault part in a winding is disassembled and replaced, and the whole winding does not need to be replaced. Accordingly, cost is saved, workload is lowered, environment is protected, fault correcting efficiency is improved, and circuit power using loss is lowered to the maximum degree.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to a kind of novel dry transformer with winding around structure.
Background technology
The conventional dry-type transformer with winding around structure at present, high and low pressure winding forms by coil direct coiling from top to bottom, in the time that circuit is short-circuited fault, larger short circuit axial force and diametral force can make winding deformation, turn insulation fracture, the master, the longitudinal insulation that are dry-type transformer are damaged, and when serious, may break wire.Because high and low pressure winding forms by the direct coiling of coil, cannot judge specifically and in which line cake position damage, cannot simply repair, will change whole winding.So not only wasted resource but also extended the repair time of fault, having increased staff's workload simultaneously.
Summary of the invention
For the problems referred to above, the utility model provides a kind of and economizes on resources, reduces the novel dry transformer of workload.
For addressing the above problem, the technical scheme that the utility model provides is: a kind of novel dry transformer, comprise iron core, described iron core is provided with at least one group of high pressure winding and low pressure winding, it is characterized in that: in every group of high pressure winding and low pressure winding, have at least one to be divided at least two sections, every section is equipped with first head and tail head, the intersegmental insulation system that is provided with, and the first head of the tail head of upper lateral section and lower lateral section is drawn and is connected through lug plate by binding post in adjacent two sections.Intersegmental insulation system is cross-over block.Each section of winding coiling, stacked when assembling, and adjacent first head and tail head is connected, ensure the globality of each winding on electric.In the time that a certain winding breaks down, the wire D.C. resistance of each section that can comprise by measuring it, judgement is that short trouble appears in which part, then only changes the part winding breaking down.Like this, when the circuit fault that is short-circuited, cause dry-type transformer winding be hit distortion, while damaging, do not need to change whole winding, only need to change the broken parts in winding, both economized on resources like this, reduce again transformer fault reparation required time.
Adopt the technical solution of the utility model, can in the time being short-circuited fault, judge the concrete position of short circuit, only remove the faulty component in winding and change, and without changing whole winding.So both saved cost, reduced workload, protected environment, improved again the efficiency of fault restoration, and made circuit electric loss be reduced to minimum.
