Description
Technical field
The present invention relates to low-voltage electrical apparatus electrical power distribution apparatus fields, especially a kind of that dropout can be adjusted outside the shell of breaker
The small-sized heavy current breaker of electric current（MCB）.
Background technology
Supply network commonly uses miniature circuit breaker（MCB）Breaker of plastic casing（MCCB）, thread off for the magnetic in such product
Device mainly has two kinds of coil type, clapper-type.Its design feature is compared, clapper-type magnetic release is generally directly using busbar as excitation
Coil, and coil type magnetic release can use different coil turns according to different current specifications.Therefore, clapper-type magnetic is de-
Button device is mostly used in the larger breaker of specification（More than 80A）, coil type magnetic release is mostly used the open circuit smaller in rated current
(it is less than 63 A) in device.Since small-size moulded case circuit breaker (MCB) is limited by space, the small-size moulded case circuit breaker of 18mm wide is maximum
Rated current can only accomplish 125A at present.
According to national standard, GB10963-2004, such miniature circuit breaker（MCB）Instantaneous trip range it is as follows,
(5.3.5 clauses)
Dropout form exchanges range direct current range
B 3I n <I≤5 I n 4I n <I≤7 I n
C 5I n <I≤10 I n 7I n <I≤15 I n
According to above-mentioned list, the drop-away current of the miniature circuit breaker of different rated current specifications be in a certain range,
It is unmodifiable after manufacture encapsulation.If it is desired to the drop-away current for adjusting product just needs to dismantle the related element of replacement of products.Cause
The protection of this such product is deficient accurately, versatility is not strong.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of simple in structure, dependable performances
Breaker tripping mechanism.
To achieve the above object, the utility model provides following technical solution：A kind of breaker tripping mechanism, including lead
Electric item and the matched yoke of conductive bar and the matched armature of the yoke and adjusting part, the armature and yoke pair
Answering has subtended angle between conductive bar side, and the adjusting part adjusts the subtended angle angle between armature and yoke, on the armature
It is provided with the matched auxiliary section of tripping with breaker.
So set, the electric current of yoke induction conductive bar is attracted armature, the auxiliary section of armature generates work to tripping
It, just can be to breaker when subtended angle angle of the adjusting part between armature and yoke is adjusted firmly so that tripping is threaded off
Drop-away current be adjusted.Therefore, technical solutions of the utility model have simple in structure, dependable performance, and drop-away current is adjustable
Technique effect.
The utility model is further arranged：The adjusting part includes connection wall, elastic component and adjusting screw, the yoke
One end and connection wall be articulated and connected, the elastic component to yoke impose active force make armature conductive bar corresponding with yoke side it
Between subtended angle be in opening trend, the adjusting screw connect with connection wall in screw-thread fit, top and the yoke phase of adjusting screw
To setting.
So set, by the built-in length to adjusting screw, just the subtended angle angle between armature and yoke can be carried out
It adjusts, further such that simple in structure, dependable performance.
The utility model is further arranged：With yoke in being wholely set, the elastic component is set as stretching the connection wall
The both ends of spring, the extension spring are connected with connection wall and armature respectively.
So set, further so that simple in structure, dependable performance.
The utility model is further arranged：The conductive bar is provided with the elongated end of fixed static contact.
So set, again further so that simple in structure, dependable performance.
