Description
Technical field
The utility model relates to a kind of breaker of plastic casing not trip gear, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology
The breaker of plastic casing of Thermomagnetic type is comparatively large because of its volume, is generally three poles or four-pole circuit breaker.Three poles or four-pole circuit breaker due to inner space abundant, by installing sensitive switch additional and interlock rotating shaft provides normally opened contact for peripheral warning circuit, realize the pyromagnetic overload-alarm non-tripping function of circuit breaker.But the miniature circuit breaker of modularization, its inner space is less, and multipole circuit breaker is assembled structure mostly, adopts traditional mode to be difficult to realize.
Summary of the invention
In view of above-mentioned Problems existing, the purpose of this utility model be to provide a kind of rational in infrastructure, volume is little, simple installation, is applicable to the Thermomagnetic type overload-alarm non-tripping device that a/D small circuit breaker uses.
For achieving the above object, the utility model takes following technical scheme:
A kind of Thermomagnetic type overload-alarm non-tripping device described in the utility model, by trip assembley therefor and modular converter two parts not formed, described not trip assembley therefor is made up of bimetal leaf, thermal element, pcb board, spring leaf, insulating part, moving contact, fixed contact, trip assembley therefor is not arranged in modular converter by screw, and modular converter is installed on-board the circuit breaker; On modular converter, be provided with relay and five binding posts.
As preferably, described bimetal leaf, thermal element, spring leaf, moving contact, fixed contact 7 adopt nonferrous materials to make respectively, and pcb board adopts two-sided copper foil covered plate material to make.
As preferably, described bimetal leaf adopts welding or riveting method to be fixed on thermal element;
As preferably, described spring leaf, fixed contact adopt welding manner to be fixed on pcb board;
As preferably, described moving contact adopts welding or riveting method to be fixed on spring leaf.
As preferably, described relay and five binding posts are arranged on the shell of modular converter.
The utility model is owing to adopting the structure of pcb board, and will not be arranged in modular converter by trip assembley therefor, therefore contact can be set in less space, and provide normally opened contact by the modular converter that circuit breaker external is assembled for peripheral warning circuit, realize the non-tripping function of pyromagnetic overload-alarm.The utility model is rational in infrastructure, volume is little, simple installation, is not only applicable to a/D small circuit breaker and uses, and is also applicable to other various circuit breakers simultaneously and is used as the use of pyromagnetic overload-alarm non-tripping device.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
With reference to accompanying drawing, a kind of Thermomagnetic type overload-alarm non-tripping device described in the utility model, by trip assembley therefor and modular converter two parts not formed, trip assembley therefor is not made up of bimetal leaf 1, thermal element 2, pcb board 3, spring leaf 4, insulating part 5, moving contact 6, fixed contact 7, trip assembley therefor is not arranged in modular converter M by screw, and modular converter M is arranged on circuit breaker N; On modular converter shell 8, be provided with relay and five binding posts.
Described bimetal leaf 1, thermal element 2, spring leaf 4, moving contact 6, fixed contact 7 all adopt nonferrous materials to make; Pcb board 3 is two-sided copper foil covered plate material, and insulating part 5, shell 8 are nonmetallic materials; Bimetal leaf 1 adopts welding or is fixed by caulking to thermal element 2; Spring leaf 4, fixed contact 7 adopt and are fixedly welded on pcb board 3; Moving contact 6 adopts welding or is fixed by caulking to spring leaf 4; Insulating part 5 is fixed on moving contact 6.1. spring leaf 4 is connected by L1 wire with the terminal of relay 9; Fixed contact 7 is connected by L2 wire with binding post 11; 2. binding post 10 is connected by wire L3 with the terminal of relay 9; Binding post 12 is connected by wire L4 with the NC terminal of relay 9; Binding post 13 is connected by wire L5 with the C terminal of relay 9; Binding post 14 is connected by wire L6 with the NO terminal of relay 9.
Working method of the present utility model is achieved like this:
Binding post 10 is connected by external cable G, the control power supply of 11, thermal element 2 bimetal leaf 1 after certain hour that is energized is heated to F force direction and bends, promote moving contact 6 by spring leaf 4 to close with fixed contact 7, by wire L1, L2, the terminal that the closure signal of moving contact 6 and fixed contact 7 is transferred to relay 9 by L3 1. with terminal 2., the normally-closed contact NC of relay 9 is opened, normally opened contact NO closes, by wire L4, L5, L6 is transferred to binding post 12, 13, 14, be connected with peripheral warning circuit by external cable E again, realize the object of this pyromagnetic overload-alarm non-tripping.As the utility model is implemented in containing many group bimetal leafs 1, the many group moving contact 6 corresponding with it and fixed contact 7 are connected by pcb board 3, as long as wherein arbitrary group of contact closure, all can realize the object of this pyromagnetic overload-alarm non-tripping utility model.
The utility model is rational in infrastructure, volume is little, simple installation, is applicable to a/D small circuit breaker and uses, and is also applicable to other various circuit breakers simultaneously and is used as the use of pyromagnetic overload-alarm non-tripping device.
