4.The paper brings out a few of measures to save energy including rational planning of grid, improvement of line loss management, public line, reactive compensation on-spot, promotion of single-phase transformer and elimination of timeworn facilities, etc.
5.Abstract: The running types of the main transformer and power transformer in the ferroalloy plant in which the author works are analysed and the economic runnig type is obtained on the main transformer and power transformer in the plant through theoretical calculation,and the purpose of energy saving is also attained.
6.This article introduced the principles of cold cathode crowbar-tube used in test of pulse modulator and CW microwave tube.It can discharge the energy on the reserved capacitance in a very short time to ensure the safety of the traveling wave tube or the multibeam klystron.Two basic circuits of the pulse transformer spring mode and self-spring mode are also presented.
