The additional power supply which is bridged on the terminals of the external direct current supply of the frequency changer comprises a battery and the control switch circuit. The control circuit comprises a sensor which is in a power-off condition, an on-off control circuit and a microprocessor unit. The sensing signals are conveyed to the microprocessor unit via an analog to digital converter; after the judgment of the control procedure stored in the EPROM, the switch signal is exported from the output interface and is conveyed to the switching circuit via a digital to analogue conversion to complete the switch changing; the emergency additional power supply is connected with the direct current terminal of the frequency changer, which can prevent the disconnection or rolling caused by the power cut.
Description
Technical field
The utility model relates to the improvement of fly frame power supplier.
Background technology
At present, stable with relative mechanical operation for the ease of the regulation and control of many motor speeds in the applied fly frame system, often supporting have a variable frequency power supply, also claims frequency converter.The quality of rove and the effect of frequency converter and operate as normal relation are greatly.During practical application, a rove unit is made up of many fly frames, by a computer realization team control, and every independent supporting frequency converter of fly frame, to realize and to guarantee that the strictness between fly frame main frame stabilized (steady-state) speed and each transmission mechanism cooperates, in order to guarantee the spinning quality of rove.Yet can meet the unexpected interruption of power supply general supply or each fly frame independent power source at the unit duration of work, the motor that frequency converter is controlled can produce not controlled free stall, thereby causes certain even all unit fly frame instructions of stopping in emergency of can't object computer sending.In the implementation behind this instruction issuing in each mechanism the parking order of original strictness upset, thereby cause fly frame full court face broken yarn or clot, making the back that restores electricity be difficult to the state of resuming work at once, cause quality accident.
Summary of the invention
The purpose of this utility model is to improve design at the problem that existing fly frame power supplier exists, set up a urgent power supply that replenishes of fly frame outage, make under the situation of emergency power off, frequency converter can work on, and execute the instruction of stopping in emergency that the control computer sends smoothly, prevent that the accident of broken yarn and clot from taking place.
Analyze in the existing structure of frequency converter, AC power port and external dc power terminal are all arranged.The external communication electric current enters frequency converter after three-phase bridge rectifier circuit is converted to DC source, and this DC source is promptly by cross-over connection electric capacity and outside dc terminal and connect.Be that the three-phase alternating-current supply of frequency adjustable removes to control the main motor speed in the fly frame by DC source footpath oscillator circuit conversion again, when the external power source fault takes place, the DC source power down that is actually frequency converter causes the stall of main motor, can't correct execution postpones the snub instruction of stopping.Externally power interruptions the time, standby DC power supply if can be switched on the dc terminal of frequency converter, promptly can keep the operating state of main motor, until finishing the instruction of stopping in emergency, thereby avoid the generation of full court broken yarn or clot accident, design of the present utility model promptly is to come from above consideration.
For this reason, in stand-by power supply storage battery that the utility model is set up (or claiming dc battery jar) and the input that matches, the output switch circuit, especially switching circuit is designed to a controlled switch road of contacting with dc battery jar confession, the widely different road of charging, control circuit then is to be the microprocessing unit of core and the fly frame off-position transducer that links to each other with the input interface of this unit with CPU by one, and the switch triggering circuit that links to each other with this unit output interface composition, the output of dc battery jar is connected on the dc terminal of frequency converter by switching circuit.The power-off signal that state sensor collects enters microprocessing unit, after CPU identification, send corresponding switching circuit triggering signal from output port, the switching circuit startup makes switch finish switching storage battery is received on the corresponding frequency converter dc terminal, realize urgent direct current supply, to guarantee the correct execution of cutoff command.
How further specify goal of the invention of the present utility model below in conjunction with symbol figure realizes.
