Description

Multipole circuit breaker with standard package
The present invention relates to a kind of multipole circuit breaker, comprising with die stamping insulation shell:
-one substrate is separated into several isolation wards side by side by dividing plate, so that place each electrode, each electrode comprises open circuit an assembly and a trip assembley therefor with separable contacts,
-one capping is installed on the substrate with closure,
-one operating mechanism is installed between a pair of supporting bracket, this mechanism have one be connected the toggle link device that spring is connected with trip dog,
-one handle is connected on this operating mechanism, and passes the opening in the capping so that use from the outside,
-one switch lever of making by insulating material, as the support of the moving contact of all electrodes, this bar is mechanically connected to and is installed on the toggle link device of doing limited rotation between closing of contact position and the open position,
The trip assembley therefor of-one release lever and electrode and the interlock of the pawl of trip dog.
According to the difference of the electric installation pattern of user, protective circuit breaker may be (the two poles of the earth, three utmost points or four utmost points) one pole or multipole.According to the rated value and the type of protecting needs of circuit breaker, some parts, particularly mechanism, switch lever, contact component, arc control device and trip gear also must suitably mate.In order to realize this purpose, circuit breaker series needs the optional model of many kinds.The assembly problem of making that causes of a great variety because part that will mate or element can not always have same profile and structure, and is difficult for exchanging.
The objective of the invention is to realize a kind of multipole circuit breaker that has standardized structural, can form several models by standard-sized assembly.
This circuit breaker according to the present invention is characterised in that:
-each assembly that opens circuit is to be made of the hexahedron monolithic box that a plastic material is made, each assembly is inserted in the corresponding isolation ward of substrate, a rest(ing) contact, arc control device and a pair of being used for be housed in the described box at least is connected to intercell connector on the trip assembley therefor of the same utmost point to a binding post
-one mechanical actuation components of forming by switch lever and mechanical component, this unit firmly is attached in the capping,
The release lever of-rotation is supported by stop, is arranged on the bottom surface of capping,
-and several grooves and otch be arranged in the dividing plate of substrate, its effect is respectively as first area supported of switch lever and release lever when the first subassembly A of the substrate formation that has open circuit assembly and trip assembley therefor group is connected with the second subassembly B that is made of the top capping that mechanical actuation components release lever and pawl are housed.
The whole various die stamping insulation case circuit breakers of performance as requested and power can both be created by the assembly that opens circuit, trip assembley therefor and the mechanical actuation components of different model.Regardless of the assembly which kind of selects for use be used to assemble, in case the number of electrode is determined, the structure of shell is exactly unique.The location of switch lever is to carry out simultaneously when the subassembly that two need assemble in advance is connected with the location of release lever.
In substrate one side, this bar is positioned in two second supportings, and these two second supportings are that the breach cross arrangement that provides in the big side plate by partition groove and box constitutes.In capping one side, first supporting of this bar is to be made of the curved bearing surface that links with the mechanism supports plate securely.
To understand more clearly that from the declarative description of the embodiment of the invention that provides subsequently other advantages and feature, embodiment only are a nonrestrictive example and expression in the accompanying drawings, in the accompanying drawings:
