Problems solved by technology

[0007] However, if the user performs a reset after opening or releasing the residual current operated circuit breaker, he cannot guarantee that the error has been eliminated
Therefore, since this problem has not been properly addressed, when the user performs a reset, there will likely be subsequent closely spaced releases of residual current operated circuit breakers.

Embodiment Construction

[0017] With reference to the above drawings, according to the present invention, a reset device associated with a residual current operated circuit breaker includes a control device 1, which on the one hand can be conveniently connected to a residual current operated circuit breaker 2 through connection points 3 and 4, so The connection point connects the control device 1 from the downstream of the residual current operated circuit breaker 2 and the upstream of the load 5, on the other hand, connects the control device 1 from the upstream of the residual current operated circuit breaker 2 through the connection points 6 and 7 to bypass The residual current operated circuit breaker does not need to be connected to the grounding system.

[0018] figure 1 And the other figures show a wire with a phase line 8 and a neutral line 9.

[0019] Therefore, the control device 1 conveniently formed by a control board is inserted between the electric wire and the residual current operated circu...

Abstract

An automatic reset device, particularly for residual current-operated circuit breakers and the like, comprising an actuator (10) for automatically resetting a residual current-operated circuit breaker(2) that is connected to an electrical line (8, 9), upstream of a load; control means (1) for actuating the actuator (10), the control means being connected upstream of the residual current-operatedcircuit breaker and downstream of the residual current-operated circuit breaker, upstream of the load, in order to bypass the residual current-operated circuit breaker when the residual current-operated circuit breaker is released, the control means including a circuit (20) for checking the connection of the reset device to the electrical line and a circuit (23) for detecting leakage current, in order to check for the presence of a leakage current, before actuating the actuator to automatically reset the residual current-operated circuit breaker.

Description

Technical field [0001] The present invention relates to an automatic reset device especially applied to a circuit breaker operated by residual current. More specifically, the present invention relates to a device that allows a residual current operated circuit breaker to be automatically reset after checking the correct operation of the system after the residual current operated circuit breaker is released. Background technique [0002] As we all know, residual current operated circuit breakers are usually provided in domestic and industrial systems to prevent a wrong current from causing danger to the user and the load connected to the wire. [0003] Essentially, the residual current-operated circuit breaker interrupts the line when it detects an error current, thereby interrupting the power supply of one or more loads located downstream. [0004] After the residual current operated circuit breaker is released, once the correct operating conditions of the system are restored, the r...
