The specification discloses a solid state auto-reset circuit breaker intended for use in ac circuits, dc circuits and ac/dc circuits. A current sensing device is used to generate a voltage drop proportional to the current flowing through the device. When the voltage drop reaches a predetermined level, resulting from an over-current condition, it trips a control means that opens a solid state switch in the line. After a defined delay interval the circuit will automatically reset to close the solid state switch. If the over-current condition still exists, the control means will again open the solid state switch. This cycle is repeated at the delay interval until the over-current condition has subsided. Circuits are also disclosed which provide over-voltage protection, through detectors which trigger the control means when an over-voltage condition is detected. The application of the invention to lightning or surge protection is also disclosed, for single line and multiline environments.

대표청구항 ▼

A pyramid protector providing line to line and line to ground over-voltage and over-current protection for each line to be protected, said protector comprising: (a) at least two conductors to be protected, and a ground conductor for dissipating over-voltage transients, (b) a multi-element primary protector having a discharge plate for each conductor and at least one ground plate for receiving over-voltage transients, (c) a current detector circuit, said circuit measuring a variable voltage drop across at least one element series mounted in said line to be protected, said current detector circuit generating a trip signal when said electrical current exceeds a predetermined level, (d) at least one normally open solid state silicon switch series mounted in each conductor following said primary conductor, said switches being responsive to a first control signal to close said switches for conduction therethrough, (e) control means for generating a first control signal in response for a voltage across the conductors to thereby close said switches to enable conduction therethrough, said control means responsive to said trip signal to shunt said first control signal to open said switch and interrupt conduction therethrough, said control means again generating said first control signal following a predetermined time interval, (f) a secondary transient protector means for conducting high voltage transient to ground, said secondary transient protector means mounted between each of said conductors and ground following said solid state silicon switches.
