Description

Small-power air compressor machine electricity-saving control device

Art

The utility model is related to a kind of control device that economize on electricity is loaded for small-sized air compressor electric motor, especially can Uninterrupted power supply is realized in mutually conversion between economize on electricity and other loop, it is ensured that a side does not interfere with pneumatics after breaking down wherein Electric motor loads the small-power air compressor machine electricity-saving control device of normal power supply.

Background technology

At present, known small-sized air compressor control device of electric motor is by air-break, A.C. contactor, hot relay Device, button switch composition, control or the power supply for starting motor.But, a variety of small-sized air compressor motor are in startup and work Produce substantial amounts of active energy in work to waste, control device of electric motor can only play the work for motor load starting and powering With.General small-sized air compressor control device of electric motor 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 small-sized air compressor control device of electric motor can not economize on electricity to motor load, this reality With a kind of small-power air compressor machine electricity-saving control device of new offer, the air compressor machine electricity-saving control device is connected on power switch and electricity 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 small work( Rate air compressor machine.

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 are through A.C. contactor and outlet terminal Sub- order is electrically connected, composition economize on electricity loop, sets an other loop A.C. contactor, the ac contactor in parallel with electricity-saving controller Device, one end is electrically connected with input wires terminal, and the other end is electrically connected with output wiring terminal, and composition economize on electricity is supplied with bypass double loop Circuit.When being operated in electricity-saving state, electric current is controlled by input wires terminal, air-break, input reactance device, economize on electricity Device, output reactance device, A.C. contactor to output wiring terminal give air compressor motor load supplying, while can be to the electricity of output Stream, voltage, power and power factor are steadily controlled.When being operated in other loop, electric current passes through input wires terminal, ac contactor Device to output wiring terminal gives air compressor motor load supplying, is particularly suitable for small-power air compressor machine.Once economize on electricity loop occurs Failure can give air compressor motor load supplying by other loop, turn there was only flash in bypass, bypass trochanter electric process in economize on electricity Switching.Secondary control loop is the mutual switching for controlling electricity-saving controller and A.C. contactor in primary circuit, work Indicate and control operation.After power supply is connected, air compressor motor starts soft start, it is therefore an objective to reduce in motor start-up moment The excessive rush of current to electricity-saving control device of electric current, while also ensureing to be transferred to bypass automatically in electric motor operation excessively stream moment. After air compressor motor operating current recovers normal, power saving operation can be gone back to again, be also manually operable electricity-saving state and bypass State.

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 air compressor machine.
