Description

Ball mill motor electricity saving control device

Art

The utility model is related to a kind of control device that economize on electricity is loaded for ball mill electric motor, especially can be in section Uninterrupted power supply is realized in mutually conversion between electricity and other loop, it is ensured that it is electromechanical not interfere with ball milling after side failure wherein The ball mill motor electricity saving control device of motivation normal power supply.

Background technology

At present, known ball mill control device of electric motor be by air-break, A.C. contactor, electrothermal relay, by Button switch is constituted, control or the power supply for starting motor.But, a variety of ball milling electric motors are starting with being produced greatly in work The active energy of amount is wasted, and control device of electric motor can only play a part of to motor load starting and powering.General ball milling Electric motor control device can not give motor electricity saving, make active power loss larger.

The content of the invention

In order to overcome the shortcomings of that existing ball mill control device of electric motor can not economize on electricity to motor load, this practicality is new Type provides a kind of ball mill electricity-saving control device, the ball mill electricity-saving control device be connected on power switch and motor load it Between in loop, motor can not only be given to provide power supply, and can be economized on electricity for motor load.

The utility model solves the technical scheme that its technical problem used：In control circuit, primary circuit input Binding post, air-break, input reactance device, electricity-saving controller, output reactance device, A.C. contactor, output wiring terminal Order is electrically connected, composition economize on electricity loop, an other loop is arranged in parallel with electricity-saving controller, by electrothermal relay and A.C. contactor Composition, input wires terminal, air-break, electrothermal relay, A.C. contactor are electrically connected with output wiring terminal, composition economize on electricity With bypass double circuit power supply circuit.When being operated in electricity-saving state, electric current passes through input wires terminal, air-break, input Reactor, electricity-saving controller, output reactance device, A.C. contactor to output wiring terminal are powered to ball mill motor load, The electric current of output, voltage, power and power factor can steadily be controlled simultaneously.When being operated in other loop, electric current passes through input Binding post, air-break, electrothermal relay, A.C. contactor to output wiring terminal are powered to ball mill motor load. It once economize on electricity loop is broken down, can be powered by other loop to ball mill motor load, bypass, bypass trochanter electricity are turned in economize on electricity During only flash switching.Secondary control loop is for controlling electricity-saving controller and A.C. contactor in primary circuit Mutual switching, work indicate and control operation.After power supply is connected, ball milling electric motor starts soft start, it is therefore an objective to reduce In the excessive rush of current to electricity-saving control device of motor start-up immediate current, while also ensureing in electric motor operation excessively stream wink Between be transferred to bypass automatically.After ball mill electric motor operation electric current recovers normal, power saving operation can be gone back to again, is also manually operable Electricity-saving state and bypass condition.

The beneficial effects of the utility model are that economize on electricity is realized on the basis of normal power supply is ensured, passes through soft start and work( The service life of rate control extension ball mill.
