Description
Technical field
The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of breaker of plastic casing apparatus for warning overload.
Background technology
Instantaneous, time-delay two segment protect functions that existing breaker of plastic casing all has.When being short-circuited in the circuit or during fault such as thermal overload, moving or thermal actuation device makes the circuit breaker action through mangneto respectively, thereby the contact state of its contents is changed, and reaches the purpose of warning.But existing Thermomagnetic type breaker of plastic casing can't inform that user's circuit breaker is owing to short circuit or thermal overload moves; And require the circuit breaker overload time only to report to the police and circuit breaker is failure to actuate at some special occasions (like fire-fighting), traditional Thermomagnetic type circuit breaker can not meet the demands.
Summary of the invention
The utility model technical problem to be solved is that a kind of breaker of plastic casing apparatus for warning overload that can be sent the overload-alarm signal by the thermal actuation device triggering of circuit breaker is provided.
The breaker of plastic casing apparatus for warning overload of the utility model includes a pedestal that is installed in the Shell of circuit breaker, in pedestal, is provided with a snap close, and the snap close middle part is hinged on the pedestal through bearing pin; The snap close rear portion is provided with the inclined-plane, has a push rod to be pressed on the said inclined-plane through the ledge of its end; Said push rod is installed on the pedestal and can be driven its straight line by the thermal actuation device of circuit breaker and moves, and the ledge of its end presses snap close through above-mentioned inclined-plane and rotates around bearing pin in push rod straight line moving process; The back side on inclined-plane is provided with spring, and spring is in the opposite direction to the depended on pressure of the force direction of snap close and push rod; The front end of said snap close contacts with the rear end of a transmission arm, and transmission arm is hinged on the pedestal through the power transmission shaft that is fixedly connected with it; On the said power transmission shaft torsion spring is installed, the active force of torsion spring makes the transmission arm rear end rely on the snap close front end; Also be fixedly connected a frizzen on the said power transmission shaft, frizzen is with transmission arm and power transmission shaft rotation, matches with the triggering sheet of a sensitive switch in the frizzen end, and the rotation of frizzen can be through triggering sheet driving sensitive switch closure or breaking off; Sensitive switch is connected in the warning circuit, can start or close warning circuit.
The original thermal actuation device of the utility model circuit breaker capable of using drives it;, sends circuit breaker alarm signal when transshipping; Both can link with tripping mechanism; The nature of trouble of indication action in circuit breaker overload action also can be when not connecting tripping mechanism, realizes that the circuit breaker overload is only reported to the police and the specific function requirement of being failure to actuate.

Embodiment
As shown in the figure, the breaker of plastic casing apparatus for warning overload includes a pedestal 1 that is installed in the Shell of circuit breaker, in pedestal, is provided with a snap close 2, and the snap close middle part is hinged on the pedestal 1 through bearing pin 3; Snap close 2 rear portions are provided with inclined-plane 4, have a push rod 5 to be pressed on the said inclined-plane 4 through the ledge of its end; Said push rod 5 is installed on the pedestal and can be driven its straight line by the thermal actuation device of circuit breaker and moves, and the ledge of its end presses snap close 2 through inclined-plane 4 and rotates around bearing pin in push rod 5 straight line moving process; The back side on inclined-plane is provided with spring 6, and the force direction of 6 pairs of snap closes of spring and the depended on pressure of push rod 5 are in the opposite direction; The front end of snap close 2 contacts with the rear end of a transmission arm 7, and transmission arm 7 is hinged on the pedestal 1 through the power transmission shaft 8 that is fixedly connected with it; On the power transmission shaft 8 torsion spring is installed, the active force of torsion spring makes transmission arm 7 rear ends rely on snap close 2 front ends; Also be fixedly connected a frizzen 9 on the power transmission shaft 8; Frizzen is with transmission arm 7 and power transmission shaft 8 rotations; Match with the triggering sheet 11 of a sensitive switch 10 in frizzen 9 ends, the rotation of frizzen can drive the closed or disconnection of sensitive switch through triggering sheet; Sensitive switch 10 is connected in the warning circuit, can start or close warning circuit.
In the utility model course of work, when circuit breaker generation overload fault and adstante febre, the thermal actuation device action of circuit breaker; Push rod 5 straight lines that drive the utility model move; And then press snap close 2 rotations, and the snap close 2 and the overlap release of transmission arm 7 are thrown off, transmission arm is rotated under the effect of torsion spring; And then, send alarm signal through power transmission shaft 8 drive frizzens 9 triggering sensitive switches.
