JP3097183U - Leakage level display Leakage breaker - Google Patents

Abstract

[Purpose] To display leakage current on a leakage breaker.
A signal from a leakage current detection circuit is displayed on a display circuit. The contact release operation circuit 2 shuts off the contacts in response to an operation signal from the circuit 3 that sends an operation signal to the contact release operation circuit when a leak occurs due to a signal from the leakage current detection circuit 1.

Description

[0001]
[Industrial applications]
The present invention relates to a new type of breaker in which a leakage level indicator is attached to a conventional leakage breaker.
[0002]
[Prior art]
Conventionally, even if there is a leak, it is used without knowing the extent to which the leak breaker operates.
[0003]
[Problems to be solved by the invention]
By displaying the degree of leakage, the insulation of the wiring circuit can be managed.
[0004]
[Means for Solving the Problems]
According to the present invention, a leakage current level is displayed on a conventional earth leakage breaker.
[0005]
[Action]
The leakage current is read by a current transformer and displayed on a display device.
[0006]
【Example】
Hereinafter, embodiments will be described with reference to the accompanying drawings.
A circuit 1 for detecting a leakage current of an earth leakage breaker; a circuit 2 for releasing a contact; a circuit for operating the circuit 2 by a signal of the circuit 1;
[0007]
[Effect of the invention]
As described above, the leakage level display breaker of the present invention uses the wiring circuit without knowing even if the leakage circuit is currently in operation until the circuit breaker operates, unless the leakage circuit is measured with a megger. The display enables the safety management of the wiring circuit. (Currently used without knowing until the Security Association regular inspection)
[Brief description of the drawings]
FIG. 1 is a structural diagram of the present invention.
1, a leakage current detection circuit 2, a contact release operation circuit 3, a circuit for transmitting an operation signal to a circuit at the time of electric leakage, and a circuit for displaying a leakage current of the circuits 4, 1.

Claims (1)

Leakage breaker characterized by indicating the level of the leakage.
