High Efficiency Amorphous Alloy Transformer In Oil Type 200 Kva , 10 Kv
Amorphous Alloy Transformer Introduction
1. High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China.
2. Excellent overload capability, capable of continuously working under 110% rated load.
3. Low loss, energy-saving, economic and maintenance free.
4. Nice appearance, small size, less installation space occupation and low engineering cost.
5. Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards.
6. Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.
high quality copper conductor
The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.
The tank is jointed with high-quality steel.
The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800KVA power are equipped with signaling thermometer and gas relay.
The core shall be earthed to the core clamping structure at one point only, through a removable external link suitably situated, and protected to allow testing after installation of the transformer.
Core clamping structure
The bottom core clamping structure shall be in electrical contact with the top core clamping structure through the tie bars, by way of the tank, or by means of a connection placed on the same side and end of the core as the removable core earthing link.
If a copper earthing connection is used between the core clamping structure and the tank, it shall be flexible, (e.g. laminated, stranded or braided), tinned at the ends, and shall be located on the same side and end of the core clamping structure as the removable core earthing link.
Care shall be taken to ensure that contact resistance between mechanical members that form part of any intentional current paths, be it circulating or to earth, is not detrimentally affected by any painting.
There shall be no sparking, that may upset Dissolved Gas Analysis (DGA) monitoring of the transformer, between bolted mechanical members during inrush or other transient conditions.
A drawing detailing the specifics of the earthing design is required as part of the transformer manuals and shall also be made available during the transformer design review.
