Problems solved by technology

[0018] H. Oil-filled transformers must use oil with many dangerous hidden dangers as insulation and cooling medium (flammable, explosive, easy to pollute);
[0019] I. In order to detect the oil medium, a complex gas chromatographic analysis test in oil must be used

Embodiment Construction

[0044] The implementation of the present invention is not limited by the following examples, and the specific implementation can be determined according to the actual situation and the above-mentioned technical solutions of the present invention.

[0045] as attached Figures 3 to 12 As shown, a wound core cable winding transformer / reactor includes a wound iron core and a cable winding 12. The wound iron core is wound in the cavity of the ring frame, and the cable winding 12 is wound outside the ring frame, while the ring frame consists of It consists of less than two sections of skeleton 14, and at least one section of skeleton 14 has holes or slots 15 for piercing the iron sheet.

[0046] In the manufacturing method of the wound iron core cable winding transformer / reactor of the present invention, the wound iron core and the cable winding 12 are installed together according to the following steps: first, the cable winding 12 is pre-wound in the hole without the iron chip thr...

Abstract

The transformer and reactor includes coiled core, annular skeleton and windings, the coiled core is wound in the cavity of annular skeleton, the windings are wound around the annular skeleton, and the annular skeleton comprises at least two sections, in at least one of which has holes for threading the core sheets. During the making, the coiled core and the windings are mounted through the following steps: winding on the skeleton without holes to form prefabricated windings; assembling the skeleton with winding and skeleton with holes to constitute annular skeleton; threading iron core sheets via the holes or slots inside the cavity of the annular skeleton to constitute the coiled core; and final forming the windings on the skeleton. The manufacture and test process is much simpler than that of conventional transformer and reactor, and the present invention can shorten greatly the production period and raise the voltage withstanding grade of non-soaked transformer and reactor.

Description

technical field [0001] The invention relates to the technical field of a cable winding transformer and a manufacturing method thereof, and relates to a coiled iron core cable winding transformer / reactor and a manufacturing method thereof. Background technique [0002] Transformers / reactors are available for all power ranges from a few W (watts) to 1000MW (megawatts). The term "transformer / reactor" generally refers to a transformer / reactor having a rated output from several hundred kW (kilowatts) to over 1000 MW, and a rated voltage from 3-4 kV (kilovolts) to very high transmission voltages. [0003] The existing medium and small-capacity transformers are commonly used in structures such as shell type, single-winding core type, three-phase, double-winding core type, and ring. Their magnetic cores, except for the ring magnets that must be wound with strip materials, the other four are made of silicon steel sheets that are stamped and laminated, su...
