摘要： A contactless intellectual switch comprises a power supply, a signal sampling means, a controlling means and thyristor assembly and so on is disclosed. The on/off of a conventional switch is replaced with turning on/off of the thyristor assembly. The contactless intellectual switch can perform various determinations on short circuit, over load and time delay, soaking out and temperature protection and provide a series of signals for controlling turning on/off of the thyristor assembly and a cooling system. The electric power can be measured automatically and current, voltage and electrical power can be displayed alternatively. The contactless intellectual switch may be connected with other networks so as to release uninterrupt power supply, in particular, with a computer so as to realize the real time monitoring and controlling.

摘要： A contactless intelligent switchgear comprises a power source device, a signal sampler, a control device, a thyristor assembly etc., and can fulfill the on/off operation of a switch by on/off control of the thyristor assembly. Further, the contactless intelligent switchgear can automatically make a short-circuit judgment, a overload delay judgment, a leakage judgment, and a temperature protection judgment, and issues control signals for turning on/off the thyristor assembly and controlling the cooling system. Furthermore, the contactless intelligent switchgear can automatically measure an electric energy, selectively display currents, voltages, and the electric energy, can be interconnected with other switchgears so as to fulfill uninterrupted power supply, and can be also connected with a computer to fulfill a real-time monitor and control.
