Abstract
A time delay contactor for answering electrical network flashing consists of a transformer, a closing coil circuit and an electronic time delay circuit. The closing coil circuit comprises an intermediate relay and a closing coil and is connected with a power supply connecting coil of the transformer to form a series circuit. The electronic time delay circuit consists of four rectifier diodes, a resistor, a capacitor and an immediate relay and is connected with a non-power supply connecting coil of the transformer through respectively leading wires from the two groups of rectifier diodes connected in parallel. The utility model has the advantages that when being used for answering the electrical network flashing, the time delay contactor can automatically restored and started, namely the time delay contactor can answer the voltage after electric network flashing to be instantaneously recovered within one second; and the time delay contactor of a motor is not required to be newly and manually started, so that the effect of the device on normal production due to power failure is avoided. The time delay contactor has wide application scope and particularly can provide reliable guarantee for the normal operation of the device as for an enterprise which is easy to generate the electrical network flashing.
Description
Technical field:
The utility model relates to the control contactor of pump motor, and particularly a kind of electrical network of tackling dodges the timing contactor that falls.
Background technology:
Pump motor dodges to fall to understanding because of the decompression outage causes contactor to reset when electrical network occurring when operation, and the contactor control circuit also disconnects simultaneously, cause the pump motor stall and supply water and interrupt, thereby need manually moisturizing again, start water pump, ordinary production is impacted.
Summary of the invention:
The purpose of this utility model is at above-mentioned existing problems, provides a kind of reply electrical network that can automatically reply startup to dodge the timing contactor that falls, and avoids water pump to cut off the water ordinary production is impacted and increases work efficiency.
The technical solution of the utility model:
A kind of timing contactor of tackling electrical network flashing, constitute by transformer, pull-in winding circuit and electronic delay circuit, the pull-in winding circuit comprises auxiliary relay and pull-in winding and connects and composes series loop with the power coil that connects of transformer, and electronic delay circuit is made up of four rectifier diodes, resistance, electric capacity and auxiliary relays and is gone between respectively from the rectifier diode of two groups of parallel connections and is connected with the non-power coil that connects of transformer.
Operation principle of the present utility model: power supply by after the transformer step-down through charging by resistance capacitance after four rectifies, and connection auxiliary relay coil makes the auxiliary contact adhesive, connect the contact coil simultaneously and make the main contacts closure, and connect circuit and carry out work.When electrical network dodges outage, because capacitor discharge causes electronic delay circuit still to be in "on" position, the auxiliary contact of auxiliary relay are still closed, and the pull-in winding circuit still is in on-state, make the automatic adhesive when power system restoration of pull-in winding and main contacts, thereby assurance equipment moves normally.
The utility model has the advantages that: when this timing contactor reply electrical network dodges, can automatically reply startup, promptly can tackle electrical network and dodge the voltage moment recovery in 1 second that falls behind, need not manually start the timing contactor of motor again, avoid equipment ordinary production to be impacted because of having a power failure.This timing contactor applied range especially dodges the enterprise that falls to being prone to electrical network, can provide reliable assurance to the normal operation of equipment.

Embodiment
Embodiment:
A kind of timing contactor of tackling electrical network flashing, constitute by transformer T, pull-in winding circuit and electronic delay circuit, the pull-in winding circuit comprises auxiliary relay KA and pull-in winding KM and connects and composes series loop with the power coil that connects of transformer T, and electronic delay circuit is made up of four rectifier diode D1, D2, D3, D4, resistance R 1, R2, capacitor C and auxiliary relay KA and is gone between respectively from the rectifier diode of two groups of parallel connections and is connected with the non-power coil that connects of transformer.
Among this embodiment, power supply by after transformer T (the model 11FB-05NL 12V) step-down through after four rectifier diode D1, D2, D3, D4. (IN4007) rectification, charge by resistance R 1 (1W10k) capacitor C (500uf/12v), and connection auxiliary relay (DSP1-DC-12V) coil makes auxiliary contact KA adhesive, connect pull-in winding (220V 1A) simultaneously and make main contacts KM closure, and connect main circuit and carry out work.When electrical network dodges, though the power supply dead electricity is still because the capacitor C discharge causes auxiliary relay KA circuit still to be in "on" position, its auxiliary contact KA is still closed, and the KM coil circuit still is in on-state, and pull-in winding and main contacts KM can directly be devoted oneself to work automatically.Experimental result shows that motor can be restarted automatically during electrical network flashing, and not influence equipment runs well.
