Two ends are welded with conductive contact, and moving contact check plate is equipped between the moving contact piece.
It further sets, the anti-coincidence brake mechanism is arranged on each single pole units of multi-pole double-break
In.
It further sets, the anti-coincidence brake mechanism is arranged in multi-pole double-break, in the multipole
It is touched in one pole of the integral type shaft of breaker with double breaks and plastic case or the double break point travelling contact of multiple poles equipped with described moving
Head check plate.
The anti-coincidence brake mechanism of the breaker with double breaks and plastic case so works：
After breaker with double breaks and plastic case is in combined floodgate, double break point travelling contact static contact corresponding with its is maintained at a level pressure
"on" position under power, when breaker with double breaks and plastic case is in the rated operational current in short circuit, more than ten times of generation, described
Dynamic and static contact between can generate a powerful electromagnetic repulsion force, this electromagnetic repulsion force makes the pulling force for overcoming touch spring
Described is dynamic
Contact is rotated to disjunction direction, at this time due to two moving contacts being arranged in moving contact supporter
Spring catch is motionless, after the moving contact embedded with moving contact check plate turns over moving contact spring pin, the double breaking points
For moving contact by between the right-angle side and two spring catch of moving contact supporter that are stuck in moving contact check plate, moving contact at this time will
It can not generate and turn round and reclosing again.
It is had an advantageous effect in that with the anti-coincidence brake mechanism of breaker with double breaks and plastic case：
It, can be to avoid double break due to being provided with anti-coincidence brake mechanism in the double break point travelling contact of breaker with double breaks and plastic case
The reclosing situation that point breaker of plastic casing is generated in short circuit breaking, the electrical hazard for reducing supply line occur.

Specific embodiment
With reference to Fig. 1~Fig. 5, by specific embodiment, the utility model is described in further detail.
It should be noted that the term " on ", " under ", " in " etc. instructions orientation or position relationship for based on attached drawing institute
The orientation or position relationship that show rather than instruction imply that signified device or element must have specific orientation, with specific
Azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
A kind of anti-coincidence brake mechanism of breaker with double breaks and plastic case, as shown in FIG. 1 to 3, bag
Moving contact supporter 5 is included, double break point travelling contact 1, moving contact check plate 3, moving contact spring pin 4 and 6, two dynamic tactile
