Problems solved by technology

However, arc fault circuit breakers currently on the market still cannot meet the safety protection requirements of existing circuits.
[0005] Moreover, ordinary rocker switches are only suitable for controlling low-power, low-current electrical appliances, and the protection switch on the socket can only be closed by manual switching
And most of the switches are single-circuit breakers, which are not safe. At present, various intelligent remote control automatic power-off switches are required in the market. The original ordinary switch socket (rocker socket) is not easy to connect to the relevant control system.

Embodiment Construction

[0046] In electrical short circuit fires, the danger of fire caused by ground fault arc short circuit is the greatest, because the arc has a large impedance and voltage drop, which limits the fault current, so that the overcurrent protection device cannot act or act in time to cut off the power supply, several The local high temperature of the ampere arc can be as high as 3000~4000°C, which is enough to ignite the nearby combustible substances to catch fire. Common circuit protection devices such as leakage protection devices, overload protection devices, circuit breakers, etc., cannot effectively protect the fault arc.

[0047] Aiming at the deficiencies in the prior art, the present invention provides a switch mechanism with an automatic tripping function. When the switch socket equipped with the switch mechanism has leakage, short circuit, overload, or arcing, the tripping module can drive the switch mechanism Action, so that the moving contact is separated from the static ...

Abstract

The invention discloses a switching mechanism with an automatic tripping function. The mechanism comprises a bracket, a swinging push rod, a connection swing arm and a lever; through operating the lever, a power source can be switched on and switched off manually, so that the function of an ordinary rocker switch can be realized. When electric leakage, short circuiting, overload and arcing occurs on a switch socket provided with the switching mechanism, a tripping module can push the swinging push rod to swing; one end of the swinging push rod contacts with the tail end of the connection swing arm so as to push the connection swing arm; the connection swing arm is separated from a catching groove under a pushing effect; the connection swing arm moves upwards with the lever under the action of a lever torsional spring, so as to be lifted, and at the same time, drives a main shaft and a moving contact thereon to be lifted, so that the moving contact can be separated from a fixed contact, and therefore, power-off protection can be realized, and security of electricity use can be ensured, and potential safety hazards can be avoided.

Description

technical field [0001] The invention belongs to the technical field of electric fire safety protection for electronic and electrical equipment, and in particular relates to a switch mechanism with an automatic tripping function. Background technique: [0002] Arcing is a natural phenomenon in which an insulator changes from non-conductive to conductive and emits light and heat after being broken down by voltage, commonly known as "arcing". Arc faults are sudden, concealed and random. Fault arc is a common safety hazard in electrical circuits. Fault arc occurs in poor insulation or poor contact of the line, and may also occur in loose wire connections, as well as aging or damaged lines and electrical circuit connections. It is easy to cause fire hazards and other safety hazards, and has a destructive impact on people's production and life. [0003] Fault arcs are generally divided into three types, namely series arcs, parallel arcs and ground arcs. In electrical short-ci...
