Another technical problem that the present invention solves is that a kind of transducer with low cost, that be used to detect circuit-breaker status is provided.
The technical scheme that the present invention solve the technical problem employing is, circuit breaker, circuit breaker comprises shell and shift fork, and shift fork has compressing tablet, on shell, the position of shift fork is provided with extending bore, and extending bore is provided with state sensor, and described state sensor comprises fixed part, two electrodes and metal elastic part, one end of metal elastic part forms with electrode and is electrically connected, and the other end is in the zone of action of compressing tablet of shift fork; Be provided with another electrode in the range of movement of metal elastic part.
The fixed part of described transducer comprises two fixed axis arranged side by side, respectively corresponding extending bore and connecting hole; Metal elastic part and electrode are arranged at the fixed axis corresponding to extending bore.Described metal elastic part is to be coiled in a wire or the torque spring that constitutes of sheet metal on the electrode, and the range of movement of an end of metal elastic part is limited by another electrode, and this electrode is arranged on elastic force direction one side of elastomeric element.
When shift fork was in the ON position, metal elastic part contacted with two electrodes, and when shift fork was in the OFF position, metal elastic part contacted with an electrode;
Perhaps, when shift fork was in the ON position, metal elastic part contacted with an electrode, and when shift fork was in the OFF position, metal elastic part contacted with two electrodes.
The present invention also provides a kind of circuit-breaker status transducer, comprises fixed part, two electrodes and metal elastic part, and electrode is arranged on the fixed part, and an end of metal elastic part is fixed on the fixed part, forms with an electrode to be electrically connected; The other end is a movable end, is provided with another electrode in elastic force direction one side of elastomeric element.
The invention has the beneficial effects as follows, by the external circuits that is connected with electrode, can detect the location status of shift fork accurately, and then detect the operating state of circuit breaker, special, transducer major part of the present invention is arranged on circuit breaker inside by the own extending bore of circuit breaker, therefore have the small and exquisite advantage of volume, and it is simple in structure, failure rate is low, with respect to like product, has significantly advantage with low cost.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a sensor states schematic diagram of the present invention, and circle is represented the cross sectional shape of fixed axis 12.
Fig. 2, the 3rd, the schematic diagram of the present invention under two states.Wherein a is the schematic diagram under the profile status, and b is the stereoscopic-state schematic diagram.
Fig. 4 is a scheme of installation of the present invention.
Abc three width of cloth figure of Fig. 5 are the profile schematic diagram that the circuit breaker of transducer is installed.
Embodiment
Referring to Fig. 1～4.
Thinking of the present invention is, because the position of shift fork 4 and the state of circuit breaker are one to one, can be by the circuit state of shift fork 4 control electrodes, short circuit/the off state of electrode in other words, make the operating state of circuit breaker and the short circuit of two electrodes/off state form corresponding relation, can detect the operating state of circuit breaker by the circuit state of detecting electrode.
Circuit breaker of the present invention has state sensor 7, and transducer comprises fixed part 1, two electrodes 2 and metal elastic part 3, and metal elastic part 3 is the metal torque spring.State sensor 7 is installed on the connecting hole of circuit breaker by bolt 8.Two electrodes are arranged on the fixed part 1, and an end of torque spring 3 is a stiff end, are fixed on the fixed part 1, and perhaps, torque spring is enclosed within on the electrode, form with this electrode to be electrically connected; The other end is a movable end; The scope of activities of metal torque spring 3 has covered two kinds of positions that make two electric pole short circuits and open circuit.
The fixed part of transducer comprises two fixed axis arranged side by side, respectively corresponding extending bore and connecting hole; Metal elastic part and electrode are arranged on the fixed axis corresponding to extending bore.
Circuit breaker of the present invention comprises shell 5 and shift fork 4, shift fork 4 has compressing tablet 6, position at shell 1 upper shift fork 4 is provided with extending bore, extending bore is provided with state sensor, described state sensor comprises fixed part 1, two electrodes 2 and metal elastic part 3, one end of metal elastic part 3 forms with electrode and is electrically connected, and the other end is in the zone of action of compressing tablet of shift fork 4; Be provided with another electrode in the range of movement of metal elastic part 3.Fixed part comprises two fixed axis arranged side by side 11,12, respectively corresponding extending bore 21 and connecting hole 22; Metal elastic part and electrode are arranged at the fixed axis corresponding to extending bore.Connecting hole is that normal circuit breaker is own, is used for two parts shell of circuit breaker is linked together, and is generally riveted joint, has promptly formed connecting hole.Two fixed axis are separately positioned on two holes, have guaranteed that transducer can not rotate to cause operational failure.
The alleged compressing tablet of the present invention is meant a part of shift fork, and common and shift fork is an one, and shown in Fig. 2 b, it is the structure of circuit breaker self, and shift fork and compressing tablet self are not inventive point of the present invention.
Concrete, described metal elastic part 3 is for being coiled in a wire or the torque spring that constitutes of sheet metal on the electrode, the range of movement of one end is limited by another electrode, this electrode is arranged on elastic force direction one side of elastomeric element, when spring is not subjected to power beyond the transducer, because flexible relation keeps all forming circuit with two electrodes and is connected, in other words, short-circuit condition.When spring was subjected to the external force skew, two electrodes opened circuit.The arrow of Fig. 1 b is represented to make spring break away from an electrode from the pressure of compressing tablet.
When the shift fork 4 that the circuit breaker of transducer is installed was in the ON position, metal elastic part 3 contacted with two electrodes, and when shift fork 4 was in the OFF position, metal elastic part 3 contacted with an electrode;
