Embodiment
Below in conjunction with specific embodiment, the utility model is described further, but protection range of the present utility model is not limited in this:
Embodiment: as shown in Figure 1, a kind of battery saving arrangement based on intelligent AC electrical network, is made up of Contactless voltage regulator TY, auto by pass unit PL, power-saving control unit KZ, electric capacity C; Contactless voltage regulator TY is connected with auto by pass unit PL, power-saving control unit KZ, electric capacity C respectively, carries out voltage-regulation according to peripheral condition by Contactless voltage regulator TY, to enter economize on electricity pressure regulation state; Auto by pass unit PL is connected with power-saving control unit KZ, and electric current leads to power-saving control unit KZ from auto by pass unit PL; Power-saving control unit KZ is in parallel with electric capacity C.
As shown in Figure 2, it is primarily of two inductance coil N for the circuit of the power-saving control unit KZ of the utility model device 1, N 2, impedance Z, electricity-saving controller composition, two inductance coil N 1, N 2connect and and resistance Z parallel connection.Due to inductance coil N 1and inductance coil N 2be wrapped in respectively above three core limbs of flux circuit each other with the voltage of other two-phase, current coil, so there is self-induction, mutual inductance between six groups of coils, the total inductance amount L of therefore formed each phase current coil 2to the macro-energy high-frequency instantaneous variation in major loop, there is induction reactance effect.Vector analysis shows, with output voltage U 0synchronous self-induced e.m.f Δ U and input voltage U iphase difference be 180 °, Δ U can at L 2on generate delayed U 0the electric current Δ i of 90 °, Δ i lags behind U altogether i270 ° that is the advanced U of Δ i i90 ° is capacity current, and it can compensating load electric current I iin part inductance current.Therefore device has the effect of the instantaneous raising power-factor of load.In addition, in operation, in three-phase iron core, the vector of magnetic flux is always zero, makes output current have the effect suppressing input three-phase imbalance.
As shown in Figure 3, described auto by pass unit PL is by two switch J 1and J 2compose in parallel, different circuit can be selected according to the closedown of respective switch.
As shown in Figure 4, described Contactless voltage regulator TY mainly contains two transformation coil BL and GB and n resistance switch unit and is formed in parallel.Each resistance switch unit by a resistance R i1and K switch i1connect and and another K switch ibe formed in parallel.
Concrete method of operation: as the 1. unit K 1closed, change to the 2. unit K 2time closed, the order of operation gearshift should be: 1, K 12closed; 2, K 2closed; 3, K 1disconnect; 4, K 12disconnect.On the contrary, from the 2. unit K 2closed change to the 1. unit K 1order time closed is then: 1, K 12disconnect; B, K 1disconnect; 3, K 2closed; 4, K 12closed, by that analogy.
As Fig. 5 is the pressure regulation conceptual scheme of the utility model device at below 0.4kV line voltage, this device enter economize on electricity pressure regulation state before the auto by pass unit PL of system default be bypass condition, i.e. J 1closed J 2open circuit, when only having an independent motor load, should make the leading full voltage starting of motor.Afterwards, just electricity-saving state can be entered, by current coil N after device foxing part license outside 2the voltage at two ends recalls a gear pressure reduction, and so far, pressure regulating device brings into operation.For the integrated load of regional power grid, then KZ can directly determine whether starting to enter economize on electricity pressure regulation state depending on peripheral condition.Many taps autotransformer is pressure regulation unit TY, exchanges each tap make N when adjustment 1on the relative input voltage U of voltage variety iwhen being 1% or less, continuous setup output voltage U can be considered as roughly 0, U 0=U i-Δ U, wherein Δ U=U i[N 2/ (N 1+ N 2)], therefore U 0=U i{ 1-[N 2/ (N 1+ N 2)], when solid-state relay SSR in TY (Solid State Relay) switch element matrix is selected to have connected N by control program 1a certain gear tap time, then Δ U is a definite value.Three-phase SSR selects by instruction and exchanges the element switched zero point, to ensure the fail safe of system.
The know-why being specific embodiment of the utility model and using described in above; if according to the change that conception of the present utility model is done; its function produced do not exceed that specification and accompanying drawing contain yet spiritual time, protection range of the present utility model must be belonged to.
