概述110kV、220kV是供电网络的主要电压等级,由于电压很高,中性点一般采用直接接地方式,由于继电保护整定配置及防止通讯干扰等方面的要求,为了限制单相短路电流,其中有部分变压器采用中性点不接地方式。
在这种运行方式下,由于雷击、单相接地短路故障等会造成中性点过电压,而且变压器大多是分级绝缘,因此过电压对中性点的绝缘造成很大威胁,必须对其设置保护装置防止事故发生。
110/220系列变压器中性点成套设备是严格按照DL/T620-1997《交流电气装置的过电压保护及绝缘配合》中关于110kV/220kV有效接地电力网中变压器中性点采用间隙保护的相关规定制造,并按照GB311.1-1997《高压输变电设备的绝缘配合》及国家电网公司2005年6月出版的《十八项电网重大反事故措施》中防止接地网和过电压事故的技术要求进行设计。
适用于110kV和220kV有效接地电力网中不接地变压器的中性点过电压保护。
为使110kV、220kV变电站内的变压器中性点设备性能可靠、安装调试及操作方便、布置简洁美观,巨亿电气还推出集变压器中性点棒间隙、间隙电流互感器、隔离开关、避雷器、端子箱及安装支架等电气设备于一体的变压器中性点成套设备。
用户可自主选用纯间隙的变压器中性点过电压保护方案,也可选用间隙与避雷器并联工作,协同保护的方案。
避雷器与隔离开关可根据工程需要,灵活组配。
隔离开关的操动机构可选择手动或电动方式。
所有产品的电气及机械性能均在出厂前完成全套的调试与检测,亦可方便的在使用现场进行再校正。

本方案适用于企事业单位等用电场合.2. 主接线说明2.1 单母线适用于单电源单台或多台主变用户,也适用于双电源(一主一备)单台或多台主变用户。
单台主变用于负荷相对较小的用户,对于负荷昼夜或季节性变化较大时,可采用多台主变。
2.2分段单母线适合于两路工作电源、两台或两台以上主变的配电所。
供一、二级负荷用电。
优点在于运行方式灵活,可以高压备投。
但高压设备多,造价高。
3. 电气二次部分3.1 根据电力负荷管理专业相关制度要求:装见总容量在100kVA及以上的专用变客户必须安装负荷管理终端设备,其工程设计应满足《福建省电力有限公司负荷管理终端安装设计导则(试行)》,其主要要求如下:1)配电柜上必须设计有一个可安装负荷管理终端的小室。
终端小室柜门上应设置玻璃观察窗,便于客户观察终端设备运行状态;观察窗应采用厚度不小于4mm的无色透明玻璃。
小室应封闭并可铅封。
2)终端小室应预装试验接线盒、专用36端子排等辅助设备。
配电柜应预留负荷管理终端设备安装接线的所需走线通道及进出线孔,包括电压、电流二次接线,开关控制、遥信线,表计485、脉冲、门禁及天馈线等。

1种 5个及以下; 2种 8个及以下; 3种 12个及以下;4.耐溶剂性: (JIS C 3003 13.1)取长20cm之试料1根,置于125±3℃的恒温炉中加热10分钟后取出,以不弯曲,不伸长之状态,将试料大约15cm之部份浸入温度60±3℃的二甲苯溶液中浸泡30分钟,取出以目视检查漆膜上有无起泡或膨胀..接着对导体径0.19以下者采用指甲法(用指甲尖端摩擦该线);导体径0.20以上者采用铅笔法(将2H之铅笔削成刃形,并对试料以约60度角及约500gf之作用力刮擦一次).再以目视检查漆膜上是否有产生气泡或凸起,但浸渍于溶剂之端部及液面之下部20mm不做为试验之对象.注:红字部份只针对漆包线,不包括三层绝缘线5. 直焊性: (JIS C 3003 14/16)同一线轴上取试样长约150mm共3条,分别将其一端40mm浸入锡炉(锡条按CNS247中规定的软焊料Sn50:Pb50)中焊锡,所深入部份应均匀完全上锡(浸渍部份上端10mm处不做试验之对象),并且不能有碳化之黑屑.6. 导体电阻测试: (漆包线JIS C 3003 17,绝缘线JIS C 3005 4.7.1)用惠登或交流电桥法测定试料之电阻,并算出温度为20℃时线长1Km之电阴,须符合附表之规定值.(该项试验依据JIS CNS 3003-1984.第19节内容)计算公式:R(Ω/km)=1米之电阻*1000*温度系数导体电阴温度数表(标准温度为20℃)三层绝缘线导体电阻如下:7. 伸长率: (JIS C 3003 18)取长约400mm之试片,在其中央部份做250mm之标线距离,以305±25mm/min之速率拉伸至断裂,试片在标线之外拉断,该次试验视为无效,连接断裂部份后测量标线间长度,依下列公式算出伸长率:伸长率(%)={连接断裂部份标线间长度(mm) –原标点距离(mm)} ÷原标点距离(mm)8. 绝缘破坏电压; (漆包线JIS C 3003 110,绝缘线JIS C 3005 4.6)漆包线: 同一轴线截取样品3根(每根长约350mm),将每根样品对折剪成两段,依下表中的张力及卷线圈数与自身对绞,绞合部分长约120mm;再在每根绞线的两根导体之间施加50Hz或60Hz的正弦交流电压,试验电压以大约500V/S的速率均匀上升,由此测下破坏电压值,但若破坏发生在5S以内者,则降低升压速度,使其在5S以上发生破坏.三层绝缘线: 同一轴线截取样品五根(每根长约400mm),将每根样品对折剪成两段,依下表中的张力及卷线圈数与自身对绞,绞合部分长约125mm;再在每根绞线的两根导体之间施加50Hz或60Hz的正弦交流电压,试验电压以大约500V/S 的速率均匀上升,直至样品被击穿,样品被击穿的电压数值须大于12000V.。

注:1、以2005年4月份的原材料价格为基础进行核算。
用户朋友可以根据原材料市价格的变化,计算出不同时期的“新”变压器原材料成本价。
其中:硅铜片:40/43元/Kg、铜导线:40元/Kg、变压器油:5.5元/Kg、片式散热器:11元/Kg、钢材1(s9):6.0元/Kg、钢材2(SS11-M):9.0元/Kg。
2、上表中斜线左方的为S9变压器的原材料参数,斜线右边的为S11-M采用玻纹油箱,所以没有片式散热器的重量参数。
3、“新”的变压器市场销售价=变压器整机原材料成本+合理的毛利。
