Description
One, technical field
The utility model relates to the control device of a kind of motor running protection control and economize on electricity, specifically a kind of electrical machine energy-saving control cubicle.
Two, background technology
The industry and the commercial motor overwhelming majority who is used to drive are the squirrel-cage AC induction motor.This type of motor has characteristics such as cost is low, sturdy and durable, reliability is high, easy to use.The operation principle of AC induction motor is to produce three-phase rotation magnetomotive force by the three-phase symmetrical current in symmetry three phase windings of stator; Wherein the first-harmonic magnetomotive force acts on smooth air gap, and produces the first-harmonic rotating magnetic field in air gap.The first-harmonic rotating magnetic field is with synchronous speed NS=60F/P rotation, cutting stator and rotor winding and induced electromotive force in winding respectively.The rotor motor-driven gesture produces electric current in having the rotor winding of closed-loop path of one's own, fundamental wave magnetic field effect in this electric current and the air gap produces electromagnetic torque, thereby makes the load of rotor rotary driving machine tool.
Motor all must consume certain energy and allow its continuous operation so that magnetic field to be provided.When the terminal voltage of supplying with the cage modle motor was constant, therefore the magnetic flux that produces also kept constant.Under rated speed, it is constant that the energy that magnetic field consumes keeps, and irrelevant with the torque that load is required, the energy size of holding load torque depends on the size of torque.When the load torque increase, the rotating speed of rotor can descend (revolutional slip increase) a little, makes the rotor current of induction rise to increase torque, and the electric current that increases in the rotor comes balance by the electric current that increases in the stator coil.On the contrary, load torque if desired reduces, and revolutional slip reduces, and rotor current descends, the also corresponding decline of stator current.But under the constant situation of terminal voltage, stator provides the electric current in magnetic field will keep constant under any load torque condition.The result is that the efficient of induction machine reduces with the minimizing of load.In fact motor seldom moves under rated condition all the time.Usually its nominal of standard electromotor of selecting all is higher than greatest requirements when driving load.Owing to this reason, selected motor almost must exceed standard, causes the low load with strong power phenomenon.
Three, summary of the invention
The purpose of this utility model provides a kind of electrical machine energy-saving control cubicle, utilizes the operating characteristic and the existing problems of squirrel-cage AC induction motor, adopts intelligent microprocessor controller, solves motor running protection and economize on electricity problem.
The technical solution of the utility model realizes in the following manner:
The intelligent motor microprocessor controller that adopts Britain's rope agate (SOMAR) company to develop recently combines with motor supply line and original motor startup protector and forms a new motor running protection control energy-saving circuit; components and parts reasonable Arrangement that its circuit was provided with in cabinet, is constituted a kind of novel electrical machine energy-saving control cubicle.
The utility model is made up of cabinet, intelligent microprocessor controller, current transformer and contactor components and parts, it is characterized in that cabinet is a rectangle, be provided with intelligent microprocessor, contactor and components and parts on the inner panel in cabinet from left to right, its circuit meets contactor K for drawing triple line from three-phase power line
1, meet K in parallel again
1Contactor K
2, passing current transformer again and intelligent microprocessor controller joins, intelligent microprocessor controller and motor join, and are parallel with bypass contactor K between current transformer triple line exit and the outlet of intelligent microprocessor controller
3, on intelligent microprocessor controller import triple line, the semiconductor protector is installed.
Compared with the prior art the utility model has the following advantages:
1, overload protection: intelligent microprocessor controller adopts distinctive software to monitor the ruuning situation of motor in real time, can judge rapidly that the load condition of motor protects.
2, open-phase protection: can in centisecond, make protection when arbitrary phase shortage, be better than other guard method and measure.
3, Presentation Function: after the electric motor starting operation, the ruuning situation that can observe motor; During operation, run indicator is bright; Power supply indicator is bright; Optimize the run indicator flicker.
4, self-starting function: when switch being placed " automatically " state, the startup protector of economize on electricity in the control cubicle can be according to the situation that detects, actuating motor voluntarily when the time of setting reaches.
5, remote control startup, hold function: (wait starting state) presses remote controller start key starter motor under stopped status; Under running status, press the remote controller stop key and shut down.
