Disclosure of Invention
In view of this, the present invention provides an electromagnetic system capable of producing a circuit breaker with a specification below 63A.
In order to realize above mesh, the utility model discloses a such electromagnetic system of circuit breaker, including yoke, the coil skeleton of installing on the yoke, iron core subassembly, coil, regulation support, iron core subassembly sets up in coil skeleton, iron core subassembly includes the ejector pin, establishes quiet iron core, the setting iron core that moves at quiet iron core opposite side on the ejector pin around establishing iron core spring, the cover on the ejector pin, the coil is around establishing on coil skeleton, the one end of coil is equipped with the vertical part, the vertical part stretches out from coil skeleton's upside, the other end of coil is equipped with the kink, the kink stretches out from coil skeleton's downside, it sets up to adjust the support to be located the coil top.
The utility model discloses further set up to the yoke include left mounting panel, right mounting panel, be the back connecting plate that the U type is connected with left mounting panel and right mounting panel, be equipped with the left draw-in groove that clamps the quiet iron core of iron core subassembly on the mounting panel of a left side, be equipped with the right draw-in groove that clamps the coil skeleton on the mounting panel of the right side, the coil is around establishing on the coil skeleton between left mounting panel and right mounting panel.
The utility model discloses further set up to adjust the support and include preceding mounting panel, back mounting panel, be the end connecting plate that the U type is connected with preceding mounting panel and back mounting panel, preceding mounting panel fixed mounting is in back connecting plate one side of yoke.
This practicality further sets up to adjust the support and adopt the copper product.
Compared with the prior art, the beneficial effects of the utility model reside in that: through the U type structure setting of the front and back mounting panel of adjusting the support and end connecting plate, compare preceding circuit breaker, it sets up the parallelly connected return circuit structure of original big ampere of electromagnetic system and changes into series circuit structure setting, can increase little ampere of specification on the basis that does not change tripping device after its return circuit improves, its internal diameter through coil skeleton and coil reduces, it has reduced electromagnetic system volume occupation space, space utilization has been increased, and the coiling shape at coil both ends changes, make its and the U type structure cooperation of adjusting the support, can let the wire of coil one end better lay wire, make little ampere of specification product need not the reposition of redundant personnel, adjust the support through adopting the copper product, make it increase the electric conductivity.
