Description
Technical field
The present invention relates to a kind of low-voltage electrical apparatus, a kind of anti-coincidence brake mechanism of breaker with double breaks and plastic case is in particulard relate to.
Background technology
Breaker of plastic casing is a kind of conventional protection electrical equipment, and it has break-make load current and to the overloading of load, short circuit
The functions such as protection, it is widely used in overload, the short-circuit protection of various electrical power distribution systems and motor.Breaker with double breaks and plastic case
It is a kind of breaker of plastic casing of newer type, traditional breaker with double breaks and plastic case uses in the supporter of double break point travelling contact
Two Locating extension springs so that dynamic and static contact of the breaker with double breaks and plastic case when closing a floodgate can keep closing a floodgate under pressure
State, disjunction state can be kept in short circuit breaking, it is past because breaker is in enormous impact caused by short circuit breaking and vibration
Toward causing breaker with double breaks and plastic case reclosing occur from being maintained at disjunction state, the generation of such case will produce sternly
The electrical hazard of weight, gently then burns breaker, heavy then circuit is on fire.
The content of the invention
It is an object of the invention to overcome traditional breaker with double breaks and plastic case in reclosing situation caused by short circuit breaking,
Anti- coincidence brake mechanism is provided with breaker with double breaks and plastic case.
The technical solution adopted in the present invention is：
A kind of anti-coincidence brake mechanism of breaker with double breaks and plastic case, including moving contact supporter, double break point travelling contact, moving contact stop
Dynamic plate, moving contact spring pin and moving contact spring, described double break point travelling contact are made up of two moving contact pieces, and described is dynamic tactile
Two ends of head piece are welded with conductive contact, and moving contact check plate is equipped between two described moving contact pieces.
Further set, described moving contact spring pin is symmetrically arranged with two sides up and down of the moving contact supporter, it is described
Double break point travelling contact be arranged between two moving contact spring pins, one end of the moving contact spring is hung on described
On moving contact spring pin, the other end is hung on the outside of the double break point travelling contact.
Further set, described moving contact check plate is arranged to Z-shaped, and the upper end of the moving contact check plate is arranged to straight
Angle, the top at the right angle by a straight line and then by an evagination arc transition to outer side edges, the moving contact check plate
Middle part is provided with mounting hole, and the bottom of the moving contact check plate is arranged to right angle, the right angle it is following by a straight line,
Again by after a straight line by an evagination arc transition to another outer side edges.
Further set, described double break point travelling contact is made up of more than two moving contact pieces, two of described moving contact piece
End is welded with conductive contact, and moving contact check plate is equipped between described moving contact piece.
Further set, described anti-coincidence brake mechanism is arranged in each single pole units of multi-pole double-break.
Further set, described anti-coincidence brake mechanism is arranged in multi-pole double-break, in the multipole double break
Stop in a pole of integral type rotating shaft for point breaker of plastic casing or the double break point travelling contact of multiple poles equipped with described moving contact
Dynamic plate.
The anti-coincidence brake mechanism of described breaker with double breaks and plastic case so works：
After breaker with double breaks and plastic case is in combined floodgate, its double break point travelling contact static contact corresponding with its is maintained under a certain pressure
"on" position, when breaker with double breaks and plastic case in short circuit, produce more than ten times of rated operational current when, described
A powerful electromagnetic repulsion force can be produced between dynamic and static contact, the pulling force for overcoming touch spring is made institute by this electromagnetic repulsion force
That states is dynamic
Contact rotates to disjunction direction, now due to two moving contacts being arranged in moving contact supporter
Spring catch is motionless, and after the moving contact embedded with moving contact check plate turns over moving contact spring pin, described double break crawl touches
By between the right-angle side and two spring catch of moving contact supporter that are stuck in moving contact check plate, moving contact now will be unable to head
Produce and turn round and reclosing again.
Had an advantageous effect in that with the anti-coincidence brake mechanism of breaker with double breaks and plastic case：
Due to being provided with anti-coincidence brake mechanism in the double break point travelling contact of breaker with double breaks and plastic case, double breaks and plastic can be avoided
Case circuit breaker occurs in reclosing situation caused by short circuit breaking, the electrical hazard for reducing supply line.

Embodiment
With reference to Fig. 1~Fig. 5, by specific embodiment, the invention will be further described.
It should be noted that the term " on ", " under ", " in " etc. instruction orientation or position relationship be based on shown in the drawings
Orientation or position relationship, rather than the device or element of instruction or hint meaning must have specific orientation, with specific side
Position construction and operation, therefore be not considered as limiting the invention.
A kind of anti-coincidence brake mechanism of breaker with double breaks and plastic case, as shown in FIG. 1 to 3, bag
