Description
Technical field
The present invention relates to a kind of chopper, in particular it relates to one has instruction leakage function
Chopper.
Background technology
In the prior art, with generally only a kind of indicating fault of circuit breaker of creepage protection function
Function, i.e. occurs various fault (short circuit, transship, leak electricity) all can indicate, and this makes the client cannot
Quickly understand the concrete reason broken down, consequently, it is possible to make time lengthening of fixing a breakdown.
Therefore, a kind of chopper that can indicate that fault type is needed in the art especially.
Summary of the invention
In order to solve defect of the prior art, the present invention provides a kind of open circuit with creepage protection function
Device.The present invention distinguishes different faults class by arranging the most proprietary dropout push rod for different faults
Type, particularly has individually electric leakage labelling instruction fault type at the product when there being electric leakage to occur, thus
Client can be allowed quickly to know the type that fault occurs.
According to an aspect of the present invention, it is provided that a kind of chopper with instruction leakage function, its feature
Being, this chopper includes: indicating mechanism and double dropout post rod mechanism；Described indicating mechanism includes electric leakage
Indication piece, is provided with electric leakage labelling；When there being leak current fault to occur, under the effect of electromagnetic force,
Electric leakage dropout push rod included by described pair of dropout post rod mechanism is ejected, thus releases and refer to described electric leakage
Show the locking of part, described electric leakage indication piece coordinate with it electric leakage indication piece spring effect under with open circuit
Device handle rotates together, thus demonstrates that the electric leakage labelling on described electric leakage indication piece is to indicate leak current fault
Generation, now this chopper is off.
