Description
Technical field
This utility model is related to a kind of economize on electricity field, particularly a kind of electricity-saving appliance for three phase alternating current motor.
Background technology
The a variety of causes such as the long-time light running of motor, irregular varying load operation lead to motor in actual motion
When, power factor is low, and the reactive power of motor and active power all have great waste, and national grid is also to factory
The power factor of business electrical has limited.Therefore, in recent years, energy-conserving product miscellaneous continues to bring out.But it is used for three-phase
Ac motor economize on electricity is also all confined to " frequency control " technology (i.e. converter), although converter has economize on electricity when running slowly
Effect, but the equipment being unable to speed governing for majority is such as：Blender, disintegrating machine, transmission equipment and machining equipment (as car, milling,
Plane, grinding machine etc.) helpless, and produce a large amount of harmonic effects motor device power utilization environments simultaneously.
Therefore, a kind of can effective compensation reactive current, the hoisting power factor energy-saving device of real-time monitoring can be provided urgently
Exploitation to be studied.
Utility model content
The problem existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of visualization three-phase automatically to save
Electrical equipment, this apparatus structure is simple, easy for installation, can effective compensation reactive current, hoisting power factor can providing show in real time
Show monitoring.
To achieve these goals, this visualization three-phase automatic electricity economizer, including：Including digital multimeter 1, described
Digital multimeter is provided with voltage measurement end, current measurement end, outfan, voltage measurement end and three-phase ac power cord
L1, L2, L3 connect respectively, and current measurement end is connected respectively with three current transformer TA and three-phase ac power cord L1, L2, L3
Connect, outfan is sequentially connected automated power compensating controller K2, relay KA4, A.C. contactor 5, chopper 6, and accesses three
Cross streams power input；The described A.C. contactor TA other end passes through a self-healing type parallel condenser 3 incoming transport electricity in parallel
Source line N.
Further, described digital multimeter 1 is that one kind can calculate and show electric current, voltage, available power, no in real time
Instrument with power, power factor.
Further, described automated power compensating controller K can be when power factor be less than setting themselves value, to described friendship
Stream catalyst sends pumping signal.
As of the present utility model preferably, described relay KA is a kind of electromagnetic relay, issues in described pumping signal
Raw closure.
As of the present utility model preferably, described A.C. contactor is a kind of quadrupole catalyst, under described pumping signal
There is adhesive.
Compared with prior art, originally automatically power off and have the beneficial effect that：
1st, arrange A.C. contactor, can be little in motor load, power factor reduce when, thus autobalance power because
Number, reduces motor temperature and noise simultaneously.
2nd, self-healing type parallel condenser is set, can effectively limiting circuitry Gao Bo, surge ripple, elimination clutter and wavelet, subtract
The consumption of few active energy.
3rd, setting digital multimeter is convenient monitors, straightforward.
Brief description
Fig. 1 is this section appliance wiring and principle schematic；
In figure：1st, digital multimeter, 2, automated power compensating controller K, 3, self-healing type parallel condenser, 4, relay
Device KA, 5, A.C. contactor, 6, chopper.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, being a kind of wiring of the electricity-saving appliance for three phase alternating current motor and principle schematic, this visualization three
Phase automatic electricity saver, including：Including digital multimeter 1, described digital multimeter is provided with voltage measurement end, electric current
Measurement end, outfan, voltage measurement end is connected respectively with three-phase ac power cord L1, L2, L3, and current measurement end is with three electric currents
Transformer TA is connected respectively with three-phase ac power cord L1, L2, L3, outfan be sequentially connected automated power compensating controller K2,
Relay KA4, A.C. contactor 5, chopper 6, and access three-phase alternating-current supply input；The described A.C. contactor TA other end leads to
Cross a self-healing type parallel condenser 3 incoming transport power line N in parallel, for imitating limiting circuitry Gao Bo, surge ripple, filter off clutter
And wavelet, reduce the consumption of active energy.
Further, described digital multimeter 1 is that one kind can calculate and show electric current, voltage, available power, no in real time
With the instrument of power, power factor, can be shown in real time after measurement end measurement parameter current of electric, voltage, active power,
The data such as reactive power, power factor.
Further, described automated power compensating controller K2 can be when power factor be less than setting themselves value, to described
A.C. contactor 5 sends pumping signal.
As of the present utility model preferably, described relay KA is a kind of electromagnetic relay, issues in described pumping signal
Raw closure.
As of the present utility model preferably, described A.C. contactor is a kind of quadrupole catalyst, under described pumping signal
There is adhesive.
Close circuit breaker 6, this electricity-saving appliance starts to show, when power factor is less than setting value, compensates control by automated power
Device K processed sends pumping signal, allows relay KA to close, A.C. contactor adhesive simultaneously, and master connected by automated power compensating controller
Loop, electricity-saving appliance puts into operation.
