低压母线 meaning in English
low-voltage busbar
Examples
- And shanghai - nanjing highway , the city s transportation is very fast convenient . our company s main business scope are as the following . xqj bridge series
公司主要产品有美式欧式系列箱式变电站， xqj电缆桥架系列，高低压母线槽系列，高低压 - The necessity of appending special protective device for middle and low voltage busbars in important consumers " substation and that in electrical auxiliary system of power plant is disserted
因此有必要研制一种造价低、原理简单、适用于中低压母线的专用母线保护。 - Microprocessor based high voltage busbar protection has rapidly expanded . on the basis of analysis grouping - principle based middle and low voltage protection are put forward . the special busbar protection has adopted effective measures so that large improvement such as simpleness , reliability , economy , sensitivity and some appending additional functions has been obtaimed
高电压等级母线微机保护已经进入到成熟发展阶段，本文在对国内外现有母线保护进行研究分析的基础上，根据中低压母线的特点，提出了一种基于分组原理的母线保护，可以很好地解决中低压母线保护的实际工程问题，使得系统简单、可靠、经济、灵活、易于扩展，而且容易附加其它的保护功能。 - Because of forecasting reactive load at first , it can detect the change of voltage at low - voltage bus from the change of reactive load or the change of voltage at high - voltage bus , then it can decide that adjusting transformer tap or capacitor switch , and avoid blindly and deficient adjusting . on the condition the reactive power is balanced and voltage qualified , it can realize the switching times of loaded taps and capacitors being efficiently decreased
由于预先预测出无功负荷，提前了解了无功功率变化的趋势，可以有助于判定低压母线电压变化是由无功负荷变化引起还是由高压侧电压变化引起，从而适时决定是调有载调压变压器分接头还是投切电容器，以此避免了盲目和不充分的调节，实现在保证无功基本平衡和电压合格率的前提下，减少有载调压变压器分接头的调节和并联电容器组的投切次数。
