Abstract
The present invention discloses a multi-plate capacitor which is suitable for the energy saving of a three-phase inductive load in electric equipment, such as the reactive power compensation of a three-phase asynchronous motor. The capacitor takes a conventional double-plate capacitor as a primary form and is added with polar plates which are arranged in a geometric form. The capacitor comprises a star-shaped capacitor and an angle-shaped capacitor, * is the symbol of a star, and * is the symbol of an angle. The capacitor with the structure can be used as a matching part for the energy saving of an inductive load in three-phase electric equipment and can be produced by the prior art of producing capacitors. Compared with the existing capacitor for a three-phase inductive load, the present invention has the advantages of small total volume, low cost and convenient assembly. The present invention is suitable for the random matching of the reactive power compensation of a three-phase asynchronous motor.
Description
The invention belongs to the electric type product, is the inductive load energy saver in the power consumption equipment.
In existing power consumption equipment, mainly contain inductive load, for example transformer, motor, motor has threephase asynchronous and single-phase motor etc., in service at inductive load, need from electrical network, draw perceptual reactive current, set up magnetic field, so the voltage of electrical network is reduced to supply with its stator winding, electric energy loss increases, and has hindered the output of active power.
People are in order to reduce electric energy loss at present, improve power factor, on some electric equipment, set up reactive power compensator, reduce electric energy loss as compensation condenser, improve the electricity consumption economy, though and overcompensation to be this compensation that is harmful to still do not solve the loss root problem that makes moderate progress, reactive power compensation should be followed variation with load variations, the particularly variation of inductive load, for example the night factory's underload or the rest of stopping work just can cause the undesirable transition effect of people unavoidably.
In inductive load equipment, have only sub-fraction to install the two-plate capacitor additional at present, as just having worn capacitor dispatching from the factory usually on the single-phase motor, what have wears a two-plate capacitor, it is start capapcitor, two the two-plate capacitors of wearing that have are start capapcitor and operation capacitor, and other saving energy and decreasing loss measure, this shows that people dispose capacitor as much as possible for energy-conservation aborning on perceptual power load, to reach the purpose of reactive power in-situ compensation, improve power factor, reduce electric energy loss deep understanding is arranged, yet account for the threephase asynchronous of very big proportion and other inductive load at present and do not have the wiring capacitance device, it why: main cause has the threephase asynchronous starting easily, the 2nd, the three-phase inductive load is worn hell to pay, because being three-phase, it to wear three pairs of two-plate capacitors, with three pairs of two-plate capacitors of present capacitor product, be exactly three capacitors, thereby volume is worn trouble greatly, thereby improved cost, therefore, present three-phase inductive load is as threephase asynchronous and other inductive load not charged container that dispatches from the factory usually.
The purpose of this invention is to provide a kind of capacitor that can assemble easily, and do not need a plurality of assembly units can be applicable to energy-conservation in the three-phase inductive load electric equipment, with be used for the three-phase inductive load with capacity capacitor at present and compare, can dwindle the capacitor volume and reduce product cost.
In order to achieve the above object, it is that a kind of multipole this capacitor of plate capacitor of embryo has star-like capacitor of three-phase and three phase angle type capacitors that the present invention has adopted with conventional two-plate capacitor, the star-like multipole plate capacitor of three-phase has i.e. 1 pole plate of a large-area metal pole plate, with corresponding 2 pole plates that three equivalent areas are arranged of 1 pole plate, and between pole plate and pole plate, arrange dielectric, on each piece pole plate, be electrically connected an electrode connection terminal and constituting star-like quadripolar plate capacitor; The multipole plate capacitor of three phase angle types is to be arranged opposite to each other by the pole plate that three areas equate, and is separated with dielectric between pole plate and pole plate, has be electrically connected that an electrode connection terminal constitutes on each piece pole plate.
The advantage of the multipole plate capacitor of the present invention is simple in structure, the technology production of available present production capacitor, easy for installation, be used for three-phase load with conventional capacitor and compare, overall volume is little, and product cost is low, adaptability is strong, as the supporting purpose that reaches local compensation of three-phase inductive load, also can regard conventional two-plate capacitor use, and be applicable to the magnetizing capacitance device when threephase asynchronous is done generating.
The invention will be further described below in conjunction with accompanying drawing
Fig. 1 is the star-like multipole plate capacitor arrangement schematic diagram of the present invention
Fig. 2 is the multipole plate capacitor arrangement of an angle of the present invention type schematic diagram
Fig. 3 is the expression symbol of this capacitor in circuit diagram is used
Fig. 4 is star-like multipole plate capacitor embodiment schematic diagram
Fig. 5 is the multipole plate capacitor of an angle type embodiment schematic diagram
As seen from Figure 1, Figure 2, the multipole plate capacitor of the present invention is made up of pole plate 1 and electrode connection terminal 2 and dielectric a, and dielectric is arranged in the capacitor body battery lead plate is separated, and plays insulating effect.
As shown in Figure 1, star-like multipole plate capacitor is by forming across dielectric in the middle of 4 pole plates, (a big pole plate and three be equal to the little pole plate of area), can constitute conventional two-plate capacitor by the big as can be seen pole plate of the star-like quadripolar plate capacitor of Fig. 1 and any one little pole plate, if three little pole plate binding posts are merged as a battery lead plate, also can form two conventional plate capacitors to big pole plate as another battery lead plate again.
By the described multipole plate capacitor of Fig. 1 as can be seen, mix electrode and just can be made into star-like quadripolar plate capacitor as long as wherein pole plate of conventional two-plate capacitor is divided into three when making this electric capacity.
As shown in Figure 2, any two pole plates of this invention multipole plate capacitor of angle type can use as conventional two-plate capacitor.
Fig. 3, a are star-like multipole plate capacitor symbol; Fig. 3 b is the multipole plate capacitor symbol of angle type.
By dwindling as can be seen on the multipole plate capacitor symbol of Fig. 3 b angle type
Symbol (pole plate) angle, just can realize the rolling technology of capacitor.
Fig. 4 and Fig. 5 are embodiment of the invention schemes, and this star-like multipole plate capacitor can be applied directly to star and connects on the load as seen from Figure 4, and it can adapt to all three-phase inductive loads as seen from Figure 5.
