The utility model discloses utilize the measurement automatic control principle of theory of mechanics and electric quantity, designed a three -phase equilibrium automatic regulating apparatus, through the utility model discloses the device can be convenient carry out the automatic adjustment and the hand regulation of loading to can show the electric current of each looks and can set up the time that the automatic adjustment was loaded, have the efficient advantage of simple structure, convenient to use and adjustment.
Description
Technical field
The utility model relates to electric load adjusting device technical field, is 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.
Utility model content
The utility model 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 utility model solves the technical scheme that its technical matters adopts:
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 the utility model device 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 utility model 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 the utility model device, 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.
