Description

The high-efficiency, energy-conserving and electromagnetical rail controller

Affiliated field: the utility model relates to a kind of high-efficiency, energy-conserving and electromagnetical rail controller.

Background technology: electromagnet is widely used in hoisting machinery, lathe, light textile, petrochemical industry machine and equipment in industrial production.All kinds of electromagnet that use during domestic industry is produced at present and technology are that China's the fifties is introduced from the former Soviet Union basically, and there is following problem in it:

1, volume is big, weight is big, consumptive material serious (copper, iron consumption big).

2, energy consumption height.

3, easily cause circle to burn during short, the moving armature bite of poor stability, life-span.

4, the interchange noise is big.

Summary of the invention: the purpose of this utility model provides that a kind of consumptive material is little, energy consumption is low, and fail safe is good, the high-efficiency, energy-conserving and electromagnetical rail controller of long service life.The purpose of this utility model connects realization by following circuit: the utility model is a kind of high-efficiency, energy-conserving and electromagnetical rail controller, the former edge joint power supply of transformer B AC380V, secondary two lines meet rectifier diode D1-D4, mid line connects capacitor C 1 negative electrode, D1, the D2 common cathode connects capacitor C 1 anode, the D1 anode connects transformer B secondary, the D2 anode connects another utmost point of B secondary, D3, D4 anode altogether connects load L coil, the D3 negative electrode connects the D1 anode, and the D4 negative electrode connects the D2 anode, and capacitor C 1 anode meets D1, the D2 common cathode, the C1 negative electrode connects transformer B secondary common port, capacitor C 2 anodes connect the C1 anode, C2 negative electrode connecting resistance R1, another termination of R1 C1 negative electrode, resistance R 2 connects the C2 negative electrode, another termination triode T base stage, triode T emitter connects the C1 negative electrode, and collector electrode connects solid-state relay SSR (-) end, SSR (+) termination C1 anode, SSR exchanges end one side joint power supply AC380V, and another exchanges termination rectifier diode D5 anode and D6 negative electrode, D5, the D8 common cathode connects the C1 negative electrode, C1 cathode connection circle L, D6, D7 is the anode connection circle L other end altogether, D3, D4 is anode connection circle L anode altogether, and D8 anode and D7 negative electrode connect and exchange AC380V.Time circuit is by R1, C2 charges and discharge circuit and forms, with solid-state relay as alternating-current switch, the ON time of control heavy current, rectification reaches commutation supply voltage magnet weak current and keeps for the time circuit direct current after AC transformation, with solid-state relay as alternating-current switch, the ON time of control heavy current is the break-make of heavy current rectifier bridge, and rectification reaches commutation supply voltage magnet weak current and keeps for the time circuit direct current after AC transformation.The utility model adopts modern electronic technology, makes product realize electromechanical integration, makes the electromagnet product change new high-tech product into.Many weakness of existing product have fundamentally been solved.According to the characteristics of electromagnetic force, the adhesive of electromagnet with keep sending following different electric current, adhesive moment passes to big electric current, just can reach the sticking purpose with Weak current during maintenance.As alternating-current switch, control the ON time (being the break-make of heavy current rectifier bridge) of heavy current with solid-state relay, rectification reaches commutation supply voltage magnet weak current and keeps for the time circuit direct current after AC transformation.This circuit is by solid-state relay SSR, heavy current rectifier bridge D5-D8, and transformer B, lower pressure rectifier D1-D4, time control R1, R2, C2, T forms.Powered on moment capacitor C 2 charging, the switch transistor T conducting, solid-state relay SSR conducting, rectifier bridge D5-D8 work, power supply magnet coil L is with heavy current, electromagnetic actuation.Capacitor C 2 chargings finish the back switch transistor T and end, and solid-state relay ends, not conducting of rectifier bridge D5-D8, and by diode D3, D4 full-wave rectification power supply magnet coil weak current, electromagnet keeps.The utility model is simple in structure, practical, current conversion is contactless, no-spark, action is quick, frequency is high, withstand voltage big, the life-span is long, satisfies the action request of high-efficiency, energy-conserving and electromagnetical iron fully.More old-fashioned electromagnet is energy-conservation greater than 95%, and the electromagnet material-saving does not have the operation noise greater than 70%, 100% water holdup, does not burn coil, safeguards simple.According to electric circuit characteristic, because adhesive moment has only more than 100 millisecond to pass to 341 volts of direct currents, only pass to 12 volts of direct currents during sticking, greatly reduce electric current, reduced energy consumption.Direct solenoid iron coil footpath reduces greatly simultaneously, reaches the material-saving purpose.The utility model can be used as the driving mechanism of brake.Now be used for JWZA100,200,300,400,500,600 type ac brakes have been widely used in industries such as machinery, metallurgy.
