Description
Affiliated technical field
The utility model relates to a kind of control device of motor with the electric loading economize on electricity that be; Especially can between economize on electricity and other loop, change each other and realize uninterrupted power supply, guarantee can not influence after a side is broken down therein the motor load electricity-saving control device of motor load normal power supply.
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 produce a large amount of active energy wastes at work, and control device of electric motor can only play the effect that starts and supply power to motor load.General control device of electric motor can not be given motor electricity saving, makes meritorious electric power energy loss bigger.
Summary of the invention
Can not be in order to overcome prior electric machine control device to the deficiency of motor load economize on electricity; The utility model provides a kind of motor load electricity-saving control device; This motor load electricity-saving control device is connected between power switch and the motor load in the loop; Can not only power supply be provided to motor, and can economize on electricity for motor load.
The utility model solves the technical scheme that its technical problem adopted: in control circuit; Primary circuit input wires terminal board, threephase load are followed the tracks of the adjusted in concert battery saving arrangement and are electrically connected in proper order with the outlet terminal daughter board; Form the economize on electricity loop; An other loop three-phase ac contactor is set; Three-phase ac contactor one end is electrically connected with the input wires terminal board, and the other end is electrically connected with the outlet terminal daughter board.When being operated in electricity-saving state, electric current is directly followed the tracks of adjusted in concert battery saving arrangement to outlet terminal daughter board through threephase load through the input wires terminal board and is supplied power to motor load, can steadily control electric current, voltage, power factor and the power of output.When being operated in the loop, side, making electric current pass through the input wires terminal board and directly supply power to motor load through three-phase ac contactor to outlet terminal daughter board.Once break down and can be supplied power to motor load by other loop in the economize on electricity loop, changeing in bypass, the bypass trochanter electric process in economize on electricity is not have to dodge disconnected switching.Secondary control loop is the open and close that are used for controlling the three-phase ac contactor in the primary circuit.After power supply is connected; Motor begins one section bypass delay working, and purpose is to reduce in that the motor start-up immediate current is excessive the rush of current of adjusted in concert battery saving arrangement is followed the tracks of in threephase load, also guarantees simultaneously to change bypass automatically in motor work overcurrent moment; Wait to delay time after a period of time; The motor operating current recover normal after, go back to power saving operation once more automatically, but also manual operation electricity-saving state and bypass condition.
The beneficial effect of the utility model is that the realization economize on electricity does not have the disconnected control of sudden strain of a muscle with conversion on the basis that guarantees normal power supply.
