Socket device with overcurrent tripping protection

Abstract

The invention provides a socket device with over-current on-off protection, which includes at least two sockets, at least one circuit breaker switch, a current monitoring unit and a microprocessor. The sockets are connected in parallel to the power supply system; the circuit breaker switch is respectively set on the path of each socket connected to the power system to open or close the circuit; the current monitoring unit is used to sense the amount of current flowing through the socket, and then generate a The group induced current value is output to the microprocessor; the microprocessor judges whether the sum of the currents flowing through the socket reaches a current safety critical value according to the induced current value, and when the sum of the currents reaches the current safety critical value, according to a The on-off setting data can selectively turn on and off all the circuit breaker switches at the same time, or turn on and off one of the circuit breaker switches, so as to ensure the safety of electricity use.

Description

technical field [0001] The invention relates to a power socket device, in particular to a socket device with over-current start-off protection. Background technique [0002] The outlet line of the building is connected to the AC mains system, and the AC power is introduced. The electrical equipment can be plugged into the outlet with a power plug to obtain operating power. Both the socket and the wire have basic specifications such as current rating and voltage rating to indicate the maximum current value and voltage value they can carry. Once the current of the power supply circuit exceeds the rated value, resulting in electrical overload, it will cause the circuit to overheat and accelerate the deterioration of the socket and wire, and even cause a fire accident. [0003] Electricity users often connect multi-level single-hole or multi-hole extension cords to the same socket socket due to insufficient awareness of electricity safety, so as to increase the number and range...

AI Technical Summary

Problems solved by technology

The current rating of a single socket is the same as the current rating of the socket device. Users often mistakenly believe that connecting electrical devices to different sockets and controlling the power consumption of each socket within the rated value can satisfy safety. Unaware that the combined amperage of all outlets actually exceeds the rating of the outlet unit and presents a safety threat

[0004] The fuses and non-fuse switches installed in the socket branch wiring inside the indoor distribution box will open and close the power supply circuit and stop the power supply when the passing current exceeds a predetermined value, but the electricity user cannot know the status of the socket. Power consumption

Furthermore, fuses and non-fuse switches both open and close the circuit when the circuit current exceeds the rated value. At this time, the circuit wire is already in an overheated state. This heat will cause the insulation coating of the wire to deteriorate, resulting in an increased risk of short circuit
