Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
A kind of breaker trip gear of the utility model is as shown in Fig. 1,2,3,4,5,6, including is used to drive breaker
The main shaft connecting lever 5 installed on the breaker semiaxis 1 and breaker closing main shaft of dropout, it is solid on the breaker semiaxis 1
Dingan County is equipped with semiaxis connecting lever 2, and trip gear, the dropout are equipped between the semiaxis connecting lever 2 and main shaft connecting lever 5
Device includes dropout holder 7, dropout energy storage retaining arm 8, keep connecting lever axis 10, dropout output toggle arm 11, thread off driving connecting lever 6 with
And dropout semiaxis 12, the holding connecting lever axis 11 are rotatably installed in 7 upper end of dropout holder, keep being fixed with dropout on connecting lever axis 11
Energy storage retaining arm 8 and dropout output toggle arm 11,8 upper end of dropout energy storage retaining arm pass through energy storage component and main shaft connecting lever
5 ends connect, and 11 upper end of dropout output toggle arm is correspondingly arranged with semiaxis connecting lever 2, when keeping connecting lever axis 10 to rotate, thread off
Output toggle arm 11 can drive semiaxis connecting lever 2 to rotate；
The dropout semiaxis 12 is rotatably installed in 7 lower end of dropout holder, is fixedly installed on dropout semiaxis 12 and is useful for limiting
The dropout semiaxis that 8 lower end of dropout energy storage retaining arm rotates and the dropout for driving dropout semiaxis 12 to rotate drive connecting lever 6.
The breaker trip gear further includes the electromagnet 4 being connect with fault-signal end, is provided on electromagnet 4
Magnet mandrel for pushing driving connecting lever 6 of threading off.
Wherein, the energy storage component includes dropout energy-stored spring 3, and 2 both ends of dropout energy-stored spring are connected separately with the first extension
