Technical field
The present invention relates to circuit protection device fields, in particular to a kind of time-delay mechanism and breaker.
Background technique
Short trouble occurs for a variety of causes such as power supply system, electrical equipment, and it is disconnected that power-supply system often relies on miniature circuit breaker
Open circuit, miniature circuit breaker malfunction leapfrog tripping is the problem of always existing.When short-circuit current is more than the same level and upper one
When grade or even again a upper pole, until then which rank of miniature circuit breaker movement has randomness, here it is miniature circuit breakers
The problem of malfunction leapfrog tripping.In folk power supply route, service cable section difference has different D.C. resistances, therefore
The line impedance that line length is formed plays certain protective effect: line short fault, line impedance occurs in user terminal
Short-circuit current limit value is limited, breaker leapfrog tripping majority is embodied in this building unit panel switches or entire building distribution
Switch trip causes large-area power-cuts.
Therefore to avoid miniature circuit breaker from tripping phenomenon of bypassing the immediate leadership occur, the miniature circuit breaker of higher level generally can be using delay
Breaker is provided with time-delay mechanism in miniature circuit breaker.When overload or short circuit, make under the action of time-delay mechanism miniature disconnected
Device delay in road disconnects.Generally prolonged in the time-delay mechanism of existing delay action circuit breaker by the way of the elastic force for overcoming spring to realize
When, delay time is short, and delay effect is poor.

The restorable under the effect of external force of time-delay mechanism 30,30 returns of time-delay mechanism, that is, dynamic iron core 35 is to far from static iron core 33
Direction movement.For dynamic iron core 35 when moving to the direction far from static iron core 33, steel wire will be finally sliding along the second lead-in chamfered 372
Protrusion 37 is moved and crossed, finally realizes return.
In the present embodiment, limiting section is the protrusion 37 set on 35 outside of dynamic iron core, elastic wire 34 and protrusion
It can mutually be restricted between 37, so that 30 delay time of entire time-delay mechanism is longer, delay effect is good.In addition, on protrusion 37
The gradient of first lead-in chamfered 371 is greater than 372 gradient of the second lead-in chamfered, so that when 30 return of time-delay mechanism, elastic wire 34
Easier it can cross over protrusion 37.
Remaining structure of the present embodiment is same as Example 1, and details are not described herein.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
