Description
The utility model belongs to electric motor starting energy saving in running controller and makes the field.
The existing background technology of the utility model is: CN90221699 number, title " energy saving motor automatic protector "; this device is to utilize three loop coils to obtain the induced signal input; utilize AC power to make the energy-conservation phase-lacking protective device of power supply; its weak point is: therefore the restart operation after this protector can not be shut down the protection motor is a technology that can not realize its every function.
Purpose of design of the present utility model is: design a kind ofly with the Single-chip Controlling thyristor, make the power-factor of load high and have an electric motor starting energy saving in running controller of defencive functions such as phase shortage, misphase, under-voltage, overvoltage, overcurrent.
Design of the present utility model is:
1, design philosophy: at present, in the middle of the power-equipment, the energy consumption of motor accounts for more than 50% of gross generation, because these motors are general to be that condition is selected with energy operate as normal under the load of maximum all, but in service in reality, but through the heavy duty of being everlasting, underloading even under zero load, move, therefore the load factor of motor is low, efficient is not high, electric energy loss is very big, for avoiding this deficiency, so designed " electric motor starting energy saving in running controller ",, reduced meritorious, the idle loss of motor as much as possible to greatest extent to reach energy-conservation.
2, design principle explanation: the utility model is with the Single-chip Controlling thyristor, thereby the power factor of load is reached more than 0.85, reduces meritorious, reactive loss, realizes economize on electricity.For in real time the variation according to the load weight becomes to motor terminal voltage, single-chip microcomputer must extract the power factor and the electric network state of load at any time, and finishes defencive functions such as phase shortage, misphase, under-voltage, overvoltage, overcurrent.The startup stage stress on the motor with different speed, greatly reduced motor adopt in the past method start surge current big, to the drawback of the impact of electrical network, and according to the weight of load, to start slope adjustable arbitrarily.Know by Fig. 2 and Fig. 3: behind the power connection, machine system enters readiness, if carry out electrical network generation misphase, the phase failure, overvoltage, under-voltage phenomenon, this controller is pretrigger not, corresponding indicator light is lighted, when above-mentioned phenomenon does not take place, press start button, single-chip microcomputer will be set the soft start motor according to starting resistor value of setting and delay time, to the startup end, the Single-chip Controlling motor enters the automatic power factor adjustment state, if the underload power factor reduces, voltage zero-cross synchronous pulse extracting circuit and current over-zero synchronous pulse extracting circuit will extract pulse signal and input to single-chip microcomputer, program by input is in advance calculated in real time, given thyristor gating circuit, the ON time of control thyristor makes motor be in electricity-saving state.If load increases the weight of, single-chip microcomputer is the time of ms level, rapidly signal is added to circuits for triggering, and shifting to an earlier date of the control thyristor angle of flow increases voltage, otherwise then anti-.
