Abstract

The invention discloses an overvoltage protector. The protector comprises a semiconductor switch circuit and a trigger circuit, wherein the first end of the semiconductor switch circuit is connected with the first end of a protected device, the second end of the semiconductor switch circuit is connected with the second end of the protected device, and the semiconductor switch circuit is used for controlling opening and closing of the overvoltage protector; and the trigger circuit is connected with a control end of the semiconductor switch circuit and used for triggering the semiconductor switch circuit. Through the overvoltage protector, the problem that effective protection cannot be provided for the protected device or circuit due to too high clamping voltage provided by the overvoltage protector in the prior art is solved, and effective and safe protection on the protected device is achieved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an overvoltage protector. Background technique [0002] Now, overvoltage protectors based on varistor technology have been widely used in electrical design to protect subsequent equipment or circuits. However, the existing technology has the following problems: the minimum clamping voltage that the overvoltage protector can provide is twice the operating voltage of the protected equipment, and the protected equipment often requires a lower clamping voltage, for example, 1.5 times the operating voltage times or 1.3 times, and some protected equipment even require the clamping voltage provided by the overvoltage protector not to be higher than its working voltage, which causes the overvoltage protector to be unable to effectively protect the subsequent equipment or circuit, that is, overvoltage The protective function of the protector has not been activated yet and the subseq...
