Description
Art
The utility model is related to a kind of control device economized on electricity for fan electromotor with electric loading, especially can be in economize on electricity
Mutually uninterrupted power supply is realized in conversion between other loop, it is ensured that a side does not interfere with fan electromotor after breaking down wherein
Load the blower fan soft start and electricity-saving control device of normal power supply.
Background technology
At present, known fan electromotor control device is by air-break, A.C. contactor, electrothermal relay, button
Switch composition, control or the power supply for starting motor.But, a variety of fan electromotors are substantial amounts of with being produced in work in startup
Active energy is wasted, and control device of electric motor can only play a part of to motor load starting and powering.General fan motor
Machine 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 fan electromotor control device can not economize on electricity to motor load, the utility model
A kind of blower fan soft start and electricity-saving control device are provided, the blower fan soft start is connected on power switch and electricity with electricity-saving control device
Between motivation load in loop, power supply can not only be provided to motor, and can be motor load economize on electricity, is particularly suitable for big work(
Rate blower fan.
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, A.C. contactor, output reactance device and output wiring terminal
Order is electrically connected, composition economize on electricity loop, sets an other loop soft initiator, the soft initiator in parallel with electricity-saving controller, one
End is electrically connected with electricity-saving controller input, and the other end is electrically connected by A.C. contactor with electricity-saving controller output end, composition
Economize on electricity and bypass double circuit power supply circuit.When being operated in electricity-saving state, electric current by input wires terminal, air-break,
Input reactance device, electricity-saving controller, A.C. contactor, output reactance device to output wiring terminal fan motor load are supplied
Electricity, while can steadily control the electric current of output, voltage, power and power factor.When being operated in other loop, electric current passes through defeated
Enter binding post, air-break, input reactance device, soft initiator, A.C. contactor, output reactance device to output wiring terminal
Fan motor load is powered, and is particularly suitable for high-power blower.Once the failure of economize on electricity loop can be by other loop fan
Motor load is powered, the only switching of flash in economize on electricity turns bypass, bypass trochanter electric process.Secondary control loop be for
The mutual switching of the electricity-saving controller and soft initiator in primary circuit is controlled, work is indicated and control operation.Connected in power supply
Afterwards, fan electromotor starts soft start, it is therefore an objective to reduce in the excessive electricity to electricity-saving control device of motor start-up immediate current
Stream impact, while also ensureing to be transferred to bypass automatically in electric motor operation excessively stream moment.Fan electromotor operating current recovers normal
Afterwards, power saving operation can be gone back to again, be 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 blower fan.
