Device, for gathering the distance between the magnetic line girth sheets of A.C. contactor body and adhesive plate signal, and by the distance for measuring letter
Number it is sent to microchip；
Microchip, for receiving the signal of range sensor transmission, and being translated into control signal frequency conversion is transferred to
Device；
Converter, for receiving the signal of microchip transmission, and according to the signal control A.C. contactor sheet for receiving
Body real time execution watt level.
The energy saver also includes：The Analog input mModule being connected between range sensor and microchip, uses
In receiving and converting the distance signal that range sensor is gathered, then the signal after conversion is sent to into microchip；
The digital quantity I/O modules being connected between microchip and converter, for receiving and convert microchip transmission
Control signal, then the signal after conversion is sent to into converter.
The inductive head of the range sensor is arranged at the sensor installation port on the adhesive plate of A.C. contactor body,
And irradiate the magnetic line girth sheets of A.C. contactor body.
The electric end of entering of the A.C. contactor body passes through converter and power electric connection.
The range sensor is laser type range sensor.
The microchip is single-chip microcomputer.
The converter adopts the miniature converters of 150W.
Compared with prior art, the present invention at least has the advantages that the present invention is connect using sensor sensing exchange
In tentaculum attracting process, the change of spacing between adhesive plate and coil plate, and by sensor acquisition to signal be sent to it is miniature
Chip, microchip sends control signal according to the distance monitored, and control signal is sent out after digital quantity I/O module converters
Give converter, optimum power consumption of the converter real-time adjustment A.C. contactor under the premise of the suction-combining force is met, when inhaling completely
After conjunction, the electric current of very little is only kept in coil, to maintain attracting state, while electric energy is saved, extend exchange and connect
The service life of tentaculum, with good application and popularization value.
