Abstract

The invention relates to a capacitive non-contact collector ring and the power supply device using the collector ring. The invention solves the problems of easy damage and poor stability in the priorcollector ring and the problem of unstable supply current output to the load by the power supply device which adopts the prior collector ring. The two electrode plates of the first capacitor and the second capacitor of the capacitive non-contact collector ring can move relatively under the precondition of keeping the relative distance and the relative area unchanged. The first electrode of the first capacitor is fixedly connected with the first electrode of the second capacitor; the second electrode of the first capacitor is fixedly connected with the second electrode of the second capacitor.The input high frequency circuit and the output high frequency circuit of the power supply device of the invention are connected via the collector ring of the invention. The capacitive non-contact collector ring of the invention can be used in the situation where the prior collector rings being used; the power supply device of the invention is suitable for the situation of high frequency power supply or low frequency power supply.

Description

technical field [0001] The invention relates to a collector ring and a power supply device using the collector ring. Background technique [0002] Generally, when the load receives power supply, it needs to obtain electric energy directly through the conductor. When there is no relative movement between the power supply and the load, it can be solved with wires or plugs and sockets. When there is relative movement between the two, simple wires, plugs and sockets cannot be satisfied, and people have designed a collector ring brush device for this purpose. The collector ring and the brush meet the relative movement between the power supply and the load at the sliding contact, and at the same time meet the smooth flow of the current in the entire circuit loop. Because there is a sliding friction contact between the collector ring and the brush, this brings a lot of inconvenience. First, due to the friction and wear between the brush and the collector ring, it needs to be repl...
