Distribution Transformer Technology and Process Features

1. Process assurance:

The same high-voltage winding coiled around the process is wound using a high-speed winding machine that mechanically tensiones the wire and maintains a constant tension. Servo system is to achieve automatic control of non-polar cable, cable compact, automatic counting accuracy; due to the high-voltage coil winding process to impose on the wire and close, so the high-voltage coil wire is solid, and the end of the insulation Between the rigid immediately followed by uncompressed margin, the same reason, the low-voltage coil as well. Therefore, with the windings of the phase winding axial height to ensure that the design size (thus ensuring the accuracy of the impedance voltage).

2. Core stack:

The iron core is assembled on the pneumatic flip-up stacking platform, and the special position-positioning tooling is adopted. The iron core and iron core are used to clamp the lower clamps, Temporarily clamp on the clamp, and use C-clamp in the space to clamp the column iron; stand mobile storage area brushing fixative, remove the temporary fixture after drying and solidification, into the body assembly process. Iron core with a solid combination of low loss and noise.

3. Body assembly:

Because the iron core without iron yoke, winding-phase units, iron yoke pad using injection molded epoxy resin pad fast, high-voltage lead and tapping lead insulation with enhanced PVC pipe wear sets and other special support combinations, in the Rolling platform for body insulation and lead assembly line, assembly speed, good quality and clean.

4 ripple tank:

Corrugated tank is corrugated production line in the use of "corrugated sheet folding machine," automatically roll specifications of the cold-rolled steel sheet folded into the drawings required by the design drawings, including the corrugated corrugated high, pitch, corrugated film, straight edge length and Total length and width. Fold good quality fast; corrugated sheet folded into the welding, to complete the folding end seam and strengthen the iron welding, the welding using argon arc welding, welding arc stability, weld penetration depth, forming a good defect. Corrugated fuel tank at the bottom, along the box, the middle of the corrugated sheet set of welded rectangular mailbox. Corrugated sheet is folded by sheet processing, the transformer work in addition to having good heat dissipation, the corrugated sheet also has the expansion of the wave wing internal pressure rise function.

5. Technical Features:

10KV, 35KV class S9, S10.S11 series of distribution transformers, the capacity range of 30-3150KVA; core for the three-phase three-column, multi-stage cylindrical; coil using the same technology, good concentricity, The main technical indicators have reached the domestic advanced level of similar products.
