Description
Art
The utility model relates to a kind of control device for motor load generation continuous change realization economize on electricity, especially can not change output frequency, ensure that the motor load affecting output power of motor and rotating speed changes automatic control electricity-saving device.
Background technology
At present, known control device of electric motor is made up of air circuit, A.C. contactor, thermal relay, push-button switch, the power supply of control or actuating motor.But a variety of motor produces a large amount of active energy wastes at work, and control device of electric motor can only play the effect starting to motor load and power.General control device of electric motor can not give motor electricity saving, makes active power energy loss larger.
Summary of the invention
Can not to the deficiency of motor load economize on electricity in order to overcome existing control device of electric motor, the utility model provides a kind of motor load to change automatic control electricity-saving device, this motor load power-saving control device to be connected between power switch and motor load in loop, power supply can not only be provided to motor, and can be the consumption of motor saving active energy.
The utility model solves the technical scheme that its technical problem adopts: in control circuit; primary circuit input wires terminal, hot protective relay, three phase power control module group, to be electrically connected with output wiring terminal order by electronic overcurrent protection device; composition economize on electricity loop; an other loop three-phase ac contactor is set; three-phase ac contactor one end is electrically connected with hot protective relay, and the other end is electrically connected with output wiring terminal.When being operated in electricity-saving state; electric current is by input wires terminal; through hot protective relay to three phase power control module group; output current is modulated by three phase power control module group; by electronic overcurrent protection device to output wiring terminal to motor, the electric current exported, voltage, power factor and power are steadily controlled.When being operated in other loop, electric current by input wires terminal through hot protective relay to three-phase ac contactor input, then by three-phase ac contactor output to binding post to motor.Once break down can by other loop to motor in economize on electricity loop, turning in bypass, bypass trochanter electric process in economize on electricity is switching without flash, produces without surge current.Secondary control loop is used to control the open and close of three-phase ac contactor in primary circuit and the work of three phase power control module group.After confession electrically connects, motor starts through one section of bypass delay working, for reducing at the excessive rush of current to three phase power control module group of motor start-up immediate current, motor work overcurrent moment also can proceed to bypass time delay automatically, stable state is entered after treating overcurrent, motor operating current recovers normal, again automatically goes back to power saving operation, also can manual operation electricity-saving state and bypass condition.
The beneficial effects of the utility model are, are not changing output frequency, and ensureing can not affect output power of motor and rotating speed reaches economize on electricity object.
