Description

TECHNICAL FIELD [0001] The present invention relates to a surge protection device, a one-touch separation device, and an earth leakage circuit breaker using the same. BACKGROUND ART [0002]

The present invention relates to a surge protection element one-touch separation device and an earth leakage breaker using the same,

More particularly, the surge protector is automatically disconnected quickly when a surge voltage or a surge current breaks it, or it is separated from the latching portion of the housing by operating the hook by a one-touch method as needed, thereby facilitating replacement and maintenance. The present invention relates to a surge protection device and a circuit breaker using the same. 2. Description of the Related Art [0002] The present invention relates to a surge protection device, and more particularly, to a surge protection device using a surge protection device.

A conventional art relating to an earth leakage circuit breaker or a surge protection device includes a utility circuit breaker No. 20-0246827 (registered on September 04, 2001)

This registration design improves the existing inconveniences of assembling all the parts separately so that ZCT, Trip Coil, Test Switch, and electronic parts are connected to the grounding detection electronic circuit board PCB) and solder (Dipper) at one time, thereby greatly reducing the number of assembling steps and improving the productivity, while also providing a technology capable of reducing the overall size.

In addition, there is a patent registration No. 10-1452839 (registration date October 14, 2014) [automatic restoration type earth leakage breaker]

This registered patent is capable of both small and efficient operation while allowing both short trip due to external factors such as lightning and short circuit trip due to internal factors such as short circuit,

Specifically, by placing the instantaneous trip means between the input terminal and the fixed contact, the instantaneous power flows into the input terminal and simultaneously flows to the coil of the instantaneous trip means. As a result, the instantaneous trip means quickly cuts off the current flow, In addition, since the instantaneous trip means and the electric trip trip means are arranged in series, the size of the housing can be reduced. Further, in the automatic restoration type earth leakage breaker according to the present invention, the instantaneous trip means and the earth leakage trip means are arranged in series on the same center axis and the instantaneous trip means and the bobbins of the earth leakage trip means are completely separated, The capacity of the coil of the instantaneous trip means can be increased irrespective of the coil, the capacity of the rated breaking current which can be blocked by the instantaneous trip means can be increased, and the connecting rod, which links the return means and the switch, The slot and the second guide slot are formed so that the protrusion of the returning means is freely movable in the second guide slot and the protrusion of the switch is freely movable in the first guide slot. Therefore, the protrusion of the switch and the protrusion of the plunger of the returning means move freely in the first and second guide slots, respectively, after the return, to maintain the position receiving the smallest force, The time required for the closing operation is finely controlled by the continuous shock at the initial stage of the movement caused by the longitudinal directional difference between the frictional force generated by the moment of the connecting rod and the plunger moving in accordance with the rotational motion and the moving direction of each connecting portion of the connecting rod Thereby preventing delay or blocking performance from being reduced.

In addition, there is a patent registration No. 10-1618210 (registration date April 28, 2016) [circuit breaker with integrated surge protector]

This patent relates to a circuit breaker integrated with a surge protector integrated with a general earth leakage breaker or an automatic restoration type earth leakage breaker,

Specifically, a leakage circuit breaker with a built-in surge and noise resistance and a SCR with improved surge resistance compared to the existing SCR are applied to reduce the occurrence of malfunctions of the circuit itself due to surge and noise. (And a surge protector-type, automatic restoration type circuit breaker), and a surge protector integrated circuit type circuit breaker (and a surge protector integrated type auto repair Type earth leakage breaker).

This patent relates to an automatic restoration type earth leakage breaker having an automatic restoration function when an earth leakage breaker is tripped due to a one-time cause of a momentary inflow of a large current such as a lightning or a surge,

Specifically, since the circuit breaker body is integrally formed with the circuit breaker and the restoring device which are integrally formed of the switching device, the instantaneous-leakage interlock trip device, and the automatic restoration device, the structure of the automatic restoration type earth leakage circuit breaker can be simplified, and the actual leakage current, Overcurrent detection is performed to quickly shut off the power supply. When the risk factors are resolved, the power supply is automatically restored by judging the cause of the power shutdown. And provides economical effect. Also, by applying the recovery solenoid, the toggle link connected to the handle and the handle is operated to perform the automatic restoration, thereby preventing the space limit in the main body of the circuit breaker.
