Abstract
The invention provides a three-phase balance automatic adjustment device which comprises a shell which is internally provided with a current transformer, an A/D converter, a CPU and a stepper motor. The current transformer is connected to user current through the wiring end on the shell and is connected to the CPU through the A/D converter. The CPU is connected to an SMS module outside the shell, a current display module on the shell and a manual and automatic transfer switch which is connected to the stepper motor. By using the mechanical measuring principle and the measurement automatic control principle of electricity amount, the three-phase balance automatic adjustment device is designed, the manual and automatic adjustment of a load can be conveniently carried out, the current of each phase can be displayed and the time of automatically adjusting the load can be set, and the three-phase balance automatic adjustment device has the advantages of simple structure, convenience in use and high adjustment efficiency.
Description
Technical field
The present invention relates to electric load adjusting device technical field, be specifically related to a kind of three-phase equilibrium self-checking device.
Background technology
Along with the develop rapidly of economy, rural subscribers' three-phase load unbalance phenomenon is more and more obvious, is mostly to use the balanced adjustment manually carrying out load at present, need to have a power failure, and the time is long in the process of load adjustment, dangerous high, uncontrollable factor of existence.
Summary of the invention
The invention provides a kind of three-phase equilibrium self-checking device, to solve the problem of the three-phase load unbalance that prior art exists.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of three-phase equilibrium self-checking device, comprise housing, enclosure interior arranges current transformer, A/D converter, CPU and stepper motor, current transformer is connected with user's electric current by the terminals on housing, current transformer is connected with CPU by A/D converter, electric current display module on the SMS module of CPU and outside, housing is connected with manual automatic transfer switch, and manual automatic transfer switch is connected with stepper motor.
Above-mentioned housing is arranged electric current adjustment and knob, interval time adjust button and power switch.
The principle of work of apparatus of the present invention is: the electric current being measured multiple user by current transformer, and transfer digital signal to by A/D converter, CPU the current value of all users is adopted into after, be shown on the charactron of electric current display module, and calculate one by one, if there is out-of-balance current value to transfinite, starting SMS module is sent in the phone of specifying by the out-of-balance current value information of transfiniting, when CPU after out-of-balance current value transfinites detects manual automatic transfer switch whether on automatic position, how to be in automatic adjusted position, Logic judgment will be started, according to the result judged, control step motor adjusts three-phase load automatically, if be on manual position, then adjust knob by related personnel by electric current and manually adjust three-phase load.
The present invention utilizes the measurement Automatic Control Theory of mechanical principle and electricity, devise a kind of three-phase equilibrium self-checking device, automatic adjustment and the manually adjustment of load can be carried out easily by apparatus of the present invention, and the electric current of each phase can be shown and the time of automatic Load adjustment can be set, there is the advantage that structure is simple, easy to use and regulated efficiency is high.
