Abstract

The invention discloses an electric automatic protection switch, which comprises a first resistor to a fifth resistor, a first capacitor to a sixth capacitor, a switch, an inductor, a relay, an amplifier, a silicon controlled rectifier and a rectifier. The electrical automatic protection switch induces a current signal in an alternating current circuit through the inductor, amplifies the induced signal through the amplifier and triggers control according to the signal, thereby being high in sensitivity, being capable of timely disconnecting a power supply when electrical equipment has a fault,and having popularization and application values.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to an electrical automatic protection switch. Background technique [0002] Electricity is a general term for disciplines or engineering fields such as the production, transmission, distribution, use, and electrical equipment manufacturing of electric energy. It is a science to create, maintain and improve limited space and environment by means of electrical energy, electrical equipment and electrical technology, covering three aspects of electrical energy conversion, utilization and research, including basic theory, applied technology, facilities and equipment, etc. In the prior art, when electrical equipment is running, faults and the like will inevitably occur. Therefore, in order to avoid deterioration of faults, a protector is needed. Contents of the invention [0003] The object of the present invention is to provide an electric automatic protection switch in order to s...
