secondary current 【電學】二次電流,次級線圈電流。

secondary diagonal

Two kinds of new on - line monitoring methods , which are based on measuring primary , secondary currents and voltages to calculate the short - circuit reactances of windings for detecting the deformation windings of power transformer , are proposed in the paper . the methods used for on - line measuring the short - circuit reactances of traction transformer in electric railways , are designed 本文提出了兩種在線監測變壓器繞組變形的方法,通過在線監測變壓器繞組原、次邊的電壓和電流量,實時計算變壓器繞組的短路電抗來判斷變壓器繞組變形情況,并對電氣化鐵路主要接線型式的牽引變壓器繞組變形的在線監測方案進行了設計。

The secondary current will be distorted when the ct undergoes saturation , which will bring some influence on the distance relay inevitably . furthermore more and more people pay attention to this problem 飽和后的電流互感器二次側輸出電流產生畸變,不可避免地對距離繼電器造成一定的影響,而且這個問題越來越受到保護工作者的重視。

Abstract the paper gives a circuit of second band active filter ? made of secondary current transmitter , it not only is of the function ? of the voltage filter , but also the current one 摘要提出一種使用第二代電流傳輸器構成的二階帶通有源濾波器電路,它既可實現電壓濾波功能,也可實現電流濾波功能

Rated secondary current 額定二次電流

Since the secondary winding is normally operated into a high-impedance circuit, the secondary current is quite small . 因為次級繞組通常輸入高阻抗的電路,因此次級電流很小。

When the secondary circuit is closed, both primary and secondary currents set up a flux in the core . 當次級電路接通時,初級電流和次級電流都在鐵芯內建立了一個磁通量。
