电力机车采用再生制动虽一直是人们的理想,但由于各种原因,在我国并未能得到推广。这主要是因为已经采用再生制动的电力机车在实际使用中存在以下缺点: (1) 功率因数低。进口的6Y_2电力机车再生时,功率因数低到只有0.3～0.5; (2) 单线区段反馈的能量,对电网产生干扰; (3) 波形畸变大,对通讯信号干扰大,对电网也产生干扰。随着时间的推移、技术的发展,有些缺点已可克服,所以我国这次向欧洲50Hz集团订
Although the adoption of regenerative braking for electric locomotive has always been the ideal of people, it has not been promoted in our country due to various reasons. This is mainly because the electric locomotives that have adopted regenerative braking have the following disadvantages in actual use: (1) The power factor is low. Imported 6Y_2 electric locomotive regeneration, the power factor is as low as 0.3 to 0.5; (2) single-wire section of the energy feedback, the power grid interference; (3) large waveform distortion, interference on the communication signal, the power grid also has interference . With the passage of time, the development of technology, some shortcomings have been overcome, so our country to the European 50Hz Group this set
