Abstract
The utility model relates to an alarm contactor, which is installed in a circuit breaker. When the circuit breaker has a short circuit or a disconnection, the utility model outputs an alarm signal. The utility model comprises a microswitch (7), a supporter (6), and a support piece (5). The microswitch (7) is arranged on the supporter (6) by the support piece (5). The supporter (6) is fixed on the magnetic conducting plate of the electromagnetic mechanism of the circuit breaker. The reed of the microswitch (7) is contacted with a nylon rod which is arranged on the lock catch of the circuit breaker. The conductor wire (1) of the microswitch (7) is connected with a control power source. The utility model has the advantages of small size (53 mm*18 mm*31 mm), high working reliability, etc. The utility model can directly use the nylon rod which is arranged on the lock catch of the circuit breaker to shift the microswitch (7).
Description
The utility model relates to a kind of Alarm contactor, is installed in the isolating switch as a kind of functional part, and when circuit breaker short circuit or disjunction, output alarm signal.
At present, employed Alarm contactor in the isolating switch, owing to have problems on the structure, the volume of whole Alarm contactor is increased (46mm * 21mm * 54mm), and the fiber-glass pole that it can only be mounted in the isolating switch tripping stirs microswitch, thereby influences functional reliability.
Task of the present utility model is that a kind of rational in infrastructure, volume is little, functional reliability is high Alarm contactor will be provided.
Task of the present utility model is finished like this, a kind of Alarm contactor, it comprises microswitch (7), support (6), supporter (5), microswitch (7) is installed on the support (6) by supporter (5), support (6) is fixed on the magnetic conductive board of circuit breaker electric magnetic mechanism, the reed of microswitch (7) contacts with the fiber-glass pole that lock for circuit breaker is buckled, and the lead (1) of microswitch (7) is connected with the control power supply.
The utility model is because after adopting said structure, (53mm * 18mm * 31mm), the fiber-glass pole that can directly utilize lock for circuit breaker to buckle is stirred microswitch (7), has improved functional reliability to have dwindled volume.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model structural drawing.
Fig. 2 is the structural drawing of microswitch of the present utility model (7).
Earlier with microswitch of the present utility model (7), corresponding separately positioning screw hole on the support (6) is aimed at, with screw (2) and add the positioning screw hole of packing ring (3) from support (6) and pass, after treating that screw (2) passes support (6), add insulating cell (8) again, make screw (2) pass insulating cell (8) and enter in the positioning screw hole on the microswitch (7), screw (2) is twisted then inward, enter opposite side until the positioning screw hole that passes on the microswitch (7), at this moment add insulating cell (8) again in opposite side, and at its outside stack supporter (5), in the positioning screw hole on the head screw-in supporter (5) of screw (2), microswitch (7) is fixed on the support (6) thereby finish.The lead (1) of burn-oning respectively on three utmost points (4) of microswitch (7) then, every lead (1) is connected with the control power supply.At last the utility model is installed on the magnetic conductive board of electromagnetic mechanism of isolating switch, and the fiber-glass pole that lock for circuit breaker is buckled contacts with the reed of microswitch (7).
When isolating switch disjunction or short circuit, the fiber-glass pole on the snap close of disconnected little device just touches the reed on the microswitch (7), thus the alerting signal of sending.
Claims (1)
1, a kind of Alarm contactor, be installed in the isolating switch, output alarm signal when circuit breaker short circuit or disjunction, it is characterized in that it comprises microswitch (7), support (6), supporter (5), microswitch (7) is installed on the support (6) by supporter (5), support (6) is fixed on the magnetic conductive board of circuit breaker electric magnetic mechanism, and the reed of microswitch (7) contacts with the fiber-glass pole that lock for circuit breaker is buckled, and the lead (1) of microswitch (7) is connected with the control power supply.
