1.This paper covers such important problems as earth connection,ups,super shielded transformer,earth free of power system and computer room, and methods to deal with them are also put forward.
2.iii) The two-stage BDC with non-isolated BDC and DC transformer is proposed.
3.By the development of high frequency switch, low frequency transformer has been withdrawn from many domains. But in the domain of UPS, linear power amplifier and the inverter output low frequency AC, for the purpose of isolation and change voltage, there is no choice but to use low frequency transformer.
4.Electronic power transformer (EPT) is a new type of power electronics device in power system, which can be applied to both the transmission system and in the distribution system. It combines power electronics technology and a high-frequency transformer to achieve the function of transformation and insulation.
5.The hand trolleys can divide into seven kinds,which are breaker hand trolley ,voltage mutual induction hand trolley, voltage mutual induction arrester hand trolley ,transformer hand trolley ,discommecting hand trolley and grounding hand trolley.
6.The Company mainly operates and acts as the agent for the following products including:frequency conversion cabinet,frequency converter,soft starter,automated control system,series of low-voltage circuit breaker,contactor,control relay,protective relay,knife switch,isolating switch,capacitor,dual power switching unit,low-voltage mutual inductor,low-voltage fuse,high-voltage vacuum circuit breaker,high-voltage mutual inductor,high-voltage load switch,high-voltage fuse,microcomputer integrated protection device and components and parts including automatic control products, Lights,button,terminal,electric meters and electromechanical products including pump,valve fan,motor,voltage transformer,wires and cables.
