Abstract
The invention relates to a duplex-feeding topology application which consists of four thyristors and two electromagnetic relays. The two electromagnetic relays form an interlocked change-over switch for controlling on and off of the four thyristors. Current of a main circuit is input to the thyristors but the electromagnetic relays; inrush current caused by electric devices can be avoided from the electromagnetic relays. The thyristors have the characteristic of allowing flow of the inrush current which is tens of common current. The duplex-feeding topology application solves the problem about inrush current of the change-over switch in the prior art.
Description
Technical field
The present invention relates to electric supply system, is that one supplies power with double circuit switching topological structure.
Technical background
At present, as shown in Figure 1, realize the conversion of two-way mains-supplied by use interlocking-type diverter switch, be widely used.But most of power consumption equipment, has inrush current when starting shooting, this inrush current may be more than the several times of usual electric current or even ten several times.Cause the mechanical contact fault of switch, the life-span of switch is low.
Summary of the invention
The present invention is exactly as shown in Figure 2, and by 4 thyristors, and two electromagnetic relays are formed.Two electromagnetic relays form the conducting shutoff that interlocking-type diverter switch controls 4 thyristors.Main road electric current stimulates the menstrual flow thyristor instead of electromagnetic relay.Electromagnetic relay can not produce the inrush current caused by power consumption equipment; Thyristor characteristically allows to pass through several times in the inrush current of usual electric current.
Present invention improves the inrush current problem of method 1 diverter switch.
