Description
Technical field
The utility model relates to leakage circuit breakers fields, and in particular to a kind of flash barrier for leakage circuit breakers.
Background technique
Miniature circuit breaker is also known as miniature circuit breaker, is suitable for exchange 50/60Hz, voltage rating 230/400V, rated current
Overload and short-circuit protection to 63A route are used, and can also be used under normal circumstances as the infrequently operation conversion of route.
Magnetic yoke is housed, its effect is to constrain the magnetic line of force of induction coil generation to external diffusion, makes the magnetic line of force inside miniature circuit breaker
Beam concentrates on around induction coil, to improve the efficiency of induction heating, and plays magnetic screening action, can be in miniature circuit breaker
The speed and magnetic that increase snap action urge the speed of short circuiting arc, improve the breaking capacity of breaker.
Existing miniature circuit breaker is generally set as the breaker of double break open type, i.e. zero curve and firewire is disconnected in open circuit,
And it is equipped with a flash barrier there are two disrupted configurations in the breaker of this structure, in each disrupted configuration, since two sides disconnect
The structure of mechanism is slightly different, therefore its arc plate shape used is also different, causes in same breaker that there are two kinds
Flash barrier of different shapes needs to process two different flash barriers in production, to influence production efficiency.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,
A kind of flash barrier for leakage circuit breakers versatile, that arc performance is good is provided.
To achieve the above object, the utility model provides following technical solution: a kind of arc for leakage circuit breakers
Plate, including the flash barrier pedestal made of plastic material, it is characterised in that: flash barrier pedestal side outer peripheral surface is equipped with protrusion
Magnetic conductive board accommodating cavity open at one end is formed between the coaming plate of flash barrier pedestal, the coaming plate and flash barrier pedestal, it is described to lead
Magnetic sheet accommodating cavity is equipped with the first positioning mechanism and the second positioning mechanism, and first positioning mechanism includes in the middle part of magnetic conductive board accommodating cavity
Equipped with the first annulus, the flash barrier pedestal is equipped in the first annulus opposite position to be connected with the first internal radius consistent first
Connect hole.
A kind of above-mentioned flash barrier for leakage circuit breakers can be further arranged to: second positioning mechanism includes leading
The first connection boss, the second connection boss and third connection boss, the external magnetic conductive board being spaced apart in magnetic sheet accommodating cavity pass through
The first positioning mechanism and the second positioning mechanism being arranged in magnetic conductive board accommodating cavity are connected to magnetic conductive board accommodating cavity.
A kind of above-mentioned flash barrier for leakage circuit breakers can be further arranged to: the coaming plate side is equipped with arc mistake
Section is crossed, arc-shaped transition section fits with the pole the N run-on tab in leakage circuit breakers.
A kind of above-mentioned flash barrier for leakage circuit breakers can be further arranged to: coaming plate is being installed on leakage circuit breakers
A side behind inside close to arc-chutes extends to form thick section to arc-chutes.
By adopting the above technical scheme, magnetic conduction is formed between the coaming plate and flash barrier pedestal of flash barrier pedestal outer peripheral surface setting
Plate accommodating cavity, magnetic conductive board are even installed in magnetic conductive board accommodating cavity by the first bindiny mechanism and the second bindiny mechanism, are not only installed
More firm and the first bindiny mechanism is set as the first annulus, flash barrier pedestal the first annulus opposite position be arranged with the
The link block that the first consistent connecting hole of one internal radius can be also arranged at this with the shell of leakage circuit breakers is connected, magnetic conduction
Setting and consistent second connecting hole of the first annulus outer diameter, are connected to outside the first annulus, the link block being arranged on pedestal on plate
It then passes through and limits flash barrier and magnetic conductive board at this inside the first annulus, in the arc-shaped transition Duan Zeyu of coaming plate side setting
The pole N run-on tab shape in leakage circuit breakers fits, so that internal structure is more beautiful, coaming plate is being installed on leakage circuit breakers
One end behind inside close to arc-chutes is provided with upset end, improves the arc ability of flash barrier, guarantees the arc extinguishing effect in arc-chutes
Fruit.
The utility model has the following beneficial effects: it is versatile, arc effect is good, improve production efficiency.
The utility model is described in further detail with reference to the accompanying drawings and examples.
