Chinese translation for "tangqian"

塘前

Example Sentences:

	1.	Tangyin substation is an important substation which has two transformer of 120mva , eight 220kv lines and three 110kv lines . tangqian line is a 110kv line specially for traction transformer substation . because traction load is high - power nonlinear and asymmetry . it will produce much harmonic and negatvie sequence current , which have done harm to compensation capacitors of tangyin substation . in recent years , the tang6c capacitor often interrupted and in 2001 july the tang7c capacitor ' s discharge pt exploded 汤阴变电站是豫北一座枢纽变电站，有2台120mva的主变， 8条220kv线路和3条110kv线路，其中的汤牵线是专为牵引变电站供电的110kv线路。由于电力机车属于大功率的非线性负荷，且三相不对称，在其运行过程中必然会产生较大的高次谐波和负序电流。
	2.	In accord with the state standard about harmonic . the harmonic permission value of tangqian line is calculated . some measurement data are shown and analyzed , and some main conclusion is drawed that the 7th harmonic voltages of tangqian line is near to the permission value , total harmonic voltage distortion ratio has oversteped the permission value . the 3th harmonic , the 5th harmonic , the 7th harmonic and the 9th harmonic current from tangqian line all overstep the permission , the largest 5th harmonic current ratio in tangsc reaches 44 % , the 7th harmonic and the 9th harmonic current in tang7c and tangsc is large maybe because the harmonic current is magnified . this paper studies the model of each element in tang yin substation 根据有关公用电网谐波的国家标准，计算出汤牵线注入汤阴变电站的谐波电流允许值，从实测数据可以得出一些重要结论：汤牵线7次谐波电压含有率的最大值接近国标中的限值，汤牵线的谐波电压总畸变率的最大值已超标；汤牵线注入电网的3 、 5 、 7 、 9次谐波电流都超标；汤6c电容器的5次谐波电流含有率较高，最高达到44 ；汤7c和汤8c电容摘要器的7次和9次谐波电流含有率偏高，原因可能是发生了谐波电流放大现象。
