中文摘要 | 有載分接頭切換裝置(OLTC或ULTC)是裝置在變壓器上供調整電壓的設備,攸關良 質電力的維持和線路損失的降低,是一項極為重要的變壓器補助裝置。而隨著高壓電、大容 量電力變壓器之產生,配置其上之 OLTC 亦隨之做了一些改變及提升進步。本文針對供電單 位超高壓變電所目前運轉中之 345KV 500MVA 電力變壓器所配置之 OLTC 基本設計做一分析 探討,期對此一設備的現場維護能有所助益。 |
英文摘要 | On Lad Tap Changer (OLTC), a device installed in the power transformer to adjust the voltage, is a very important ancillary device for the maintenance of high quality power and the decrease of line loss. Accompaning with the production of high voltage and large capacity power transformer, OLTC has been modified and upgraded to some degree. This article is an overall basic study on the OLTC for 345KV 500MVA power transformers used by the EHV Substation of Electrical System Department. It would give some help for the site maintenance of the power transformer. |
