In order to ensure the continuity powered, the overload-alarm non-tripping device of breaker is widely adopted.It is arranged on disconnected
Road device load end, directly collection a phase, b phase, c phase operating current signal, when load current is specified more than the breaker of certain multiple
During electric current (in), continue in the regular hour, breaker can provide an alarm actuating contact signal, remind user load super negative
Lotus, and do not execute dropout.
Utility model content
The purpose of this utility model is it is simply that report to provide a kind of hm60-400 of breaker with new structure to transship
Alert not trip gear.
To achieve these goals, the utility model employs a kind of technical scheme below: the hm60-400 mistake of breaker
Carry alarm non-tripping device, for acquisition testing three-phase operating current signal, realize alarm non-tripping, including pedestal, draw bar,
Bimetal leaf assembly, microswitch and reduction torsion spring；Draw bar activity is erected on pedestal, bimetal leaf assembly totally three groups uniform
Interval setting is simultaneously connected with draw bar transmission respectively, and microswitch is arranged on pedestal, and reduction torsion spring is connected to pedestal and traction
The elastic force that draw bar resets is provided between bar；When breaker has overload current, bimetal leaf is heated and produces bending, drives traction
Bar rotates counterclockwise, and then triggers the contact of microswitch, so that contact is converted to normally closed by normally opened, provides the user with an overload
Alarm actuating contact signal.
Described pedestal includes left socle, right support and is connected to crossbeam between left socle and right support, on crossbeam
It is provided with microswitch mounting seat, described microswitch is arranged in this microswitch mounting seat.
Described draw bar includes drawing bar body, is interval with the u shape of three oblique upper openings in traction bar body
Groove, in traction bar body, the position corresponding to microswitch is provided with the projection of the contact for triggering microswitch.
Described bimetal leaf assembly includes heater element, bimetal leaf and adjusting screw, the bottom of bimetal leaf and heating
The bottom of element is connected, and the oblique outside of top fold of bimetal leaf is stretched out, and adjusting screw is connected to the upper end phase of bimetal leaf
Skewed and corresponding on draw bar u shape groove cutting ferrule should be formed be connected.
Described draw bar is provided with locating piece, and this locating piece can contact the return shape being connected to draw bar with the crossbeam of pedestal
State is positioned.
The hm60-400 overload-alarm non-tripping device of breaker of the present utility model due to employing above technical scheme,
There is following significant advantage and feature:
1), structure is simply it is easy to assemble；
2), directly drive draw bar to rotate by bimetal leaf heated bending, and then trigger microswitch, output is reported to the police and touched
Point signal.
3), improve the continuity of power supply.
