Problems solved by technology

[0002] In daily electricity consumption, due to the characteristics of the power grid itself, the user's power supply often has problems such as overvoltage, low voltage, surge voltage, and lightning strike voltage. If these abnormal phenomena are not eliminated in time and protective measures are taken, then the connection The electrical equipment in the power supply will be impacted by overvoltage or low voltage, which will even affect the safety of life, especially for children.

Abstract

The invention discloses a power supply device protection device which is used for protection of a power supply socket. The power supply device protection device comprises an insulating shell which covers the pedestal of the power supply socket; metal electrodes which are provided with a zero line, a ground line and a live line, wherein one end of each of the zero line, the ground line and the live line is connected with the power supply socket; a first voltage-dependent resistor component which is connected with the zero line electrode and the ground line electrode; and a second voltage-dependent resistor component which is connected with the live line electrode and the ground line electrode. The beneficial effects of the power supply device protection device are that the power supply device protection device is convenient to use, mature in technology, low in cost, easy to popularize and use, widely applicable to different power supply protection occasions and particularly suitable for protection of household power supply devices and socket wiring detection.

Description

technical field [0001] The invention relates to a protection device for a power supply. Background technique [0002] In daily electricity consumption, due to the characteristics of the power grid itself, the user's power supply often has problems such as overvoltage, low voltage, surge voltage, and lightning strike voltage. If these abnormal phenomena are not eliminated in time and protective measures are taken, then the connection The electrical equipment in the power supply will be impacted by overvoltage or low voltage, which will even affect the safety of life, especially for children. Contents of the invention [0003] In view of the above problems, the present invention provides a power supply protection device. [0004] The technical solution adopted by the present invention to solve technical problems is: [0005] A protection device for a power supply, used to protect a power socket, including: an insulating shell, the insulating shell is covered on the bas...
