描述
SIEMENS 505-6660
干式變壓器：依靠空氣對流進行自然冷卻或增加風(fēng)機冷卻，多用于高層建筑、高速收費站點用電及局部照明、電子線路等小容量變壓器。干式：絕緣介質(zhì)為環(huán)氧樹脂、浸漬漆、杜邦紙網(wǎng)格布、空氣等，散熱介質(zhì)為空氣等（無滲漏，受到生設(shè)備等的限制一般用于35kV級及以下，容量不是很大，成本較高）
油浸式變壓器：依靠油作冷卻介質(zhì)、如油浸自冷、油浸風(fēng)冷、油浸水冷、強迫油循環(huán)等。油浸式：絕緣介質(zhì)為變壓器油、紙板等，散熱介質(zhì)為變壓器油等（有可能會滲漏，環(huán)保性差了一點，成本低一點）
變壓器（Transformer）是利用電磁感應(yīng)的原理來改變交流電壓的裝置，主要構(gòu)件是初級線圈、次級線圈和鐵芯（磁芯）。主要功能有：電壓變換、電流變換、阻抗變換、隔離、穩(wěn)壓（磁飽和變壓器）等。按用途可以分為：電力變壓器和特殊變壓器（電爐變、整流變、工頻試驗變壓器、調(diào)壓器、礦用變、音頻變壓器、中頻變壓器、高頻變壓器、沖擊變壓器、儀用變壓器、電子變壓器、電抗器、互感器等）。電路符號常用T當(dāng)作編號的開頭.例:T01,T201等。
