  前言

本规范由肯尼亚电力和照明公司（简称 KPLC）标准部与网络管理部合作编写，规定了杆式三相油式配电变压器的要求。该规范供 KPLC 在采购配电变压器时使用。
希望制造商能提供高效节能的标准设计变压器，以提高效率并显著节省初期成本。制造商还应提交相关资料，证明其对本规范范围内的产品具有令人满意的服务经验。

  1.范围

1.1.本规范适用于新制造的油浸式、空气冷却、户外型杆式三相配电变压器，用于 50 赫兹运行的 11 千伏和 33 千伏配电系统。
本规范适用于下列电压比和额定值的变压器：
  • 11000 / 420 V : 50 KVA , 100 KVA , 200 KVA 11000 / 420 V : 50 KVA , 100 KVA , 200 KVA 11000//420V:50KVA,100KVA,200KVA11000 / 420 \mathrm{~V}: 50 \mathrm{KVA}, 100 \mathrm{KVA}, 200 \mathrm{KVA} 和 315 千伏安
  • 33000/420V: 50 KVA , 100 KVA , 200 KVA 50 KVA , 100 KVA , 200 KVA 50KVA,100KVA,200KVA50 \mathrm{KVA}, 100 \mathrm{KVA}, 200 \mathrm{KVA} 和 315 KVA .
    1.2.该规范还包括测试、检查和应由制造商填写、签署并提交评标的《保证技术细节表》。
    1.3.本规格书规定了公司（KPLC）可接受使用的柱上安装式三相配电变压器的最低要求（包括防止破坏的功能），供应商有责任确保在制造 KPLC 配电系统使用的变压器时，设计充分、工艺精良、工程设计规范良好，并符合标准、规范和适用的规定。
    1.4.本规范无意包含合同的所有必要条款。
