Abstract
The utility model discloses a three-in-one motor capacitor, which can be used as a carrying energy-saving part with wattless compensation for a three-phase motor. The utility model is used for the local capacitive compensation of the motor. The utility model can enhance the factor of the motor power, can reduce the consumption, and can improve the power supply quality of the electric network. The capacitor uses conventional double-pole plate capacitors as a basic type. Three pairs of double-pole plate capacitors are combined together, so that a conveniently assembled three-phase motor capacitor with multiple end heads is formed. The three-in-one motor capacitor can be produced by the skill of producing the existing capacitor. Compared with the existing capacitor used for the three-phase inductive load, the three-in-one motor capacitor has the advantages of small whole size, low cost, and convenient assemblage.
Description
The utility model 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 have threephase asynchronous and single-phase motor etc., in service at inductive load, need from electrical network, draw perceptual reactive current, set up magnetic field from supplying with its stator winding, so the voltage of electrical network is reduced, and electric energy loss increases, and has hindered the output of active power.
People improve power factor in order to reduce electric energy loss at present.Power capacitor is set as reactive power compensator on grid equipment, reduces electric energy loss, improve the electricity consumption economy.And overcompensation is harmful to, root problem does not still solve though this compensation makes moderate progress to loss, 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.Thereby people are in transformer station, electrical network, electric power system, and in the adjustment and fluctuation problem of voltage, design stub capacity transfer power capacitor and change over switch capacity transfer capacitor reduce transition effect again.
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---start capapcitor, what have wears two two-plate capacitors---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, the problem that reduces electric energy loss has deep understanding, yet account for the threephase asynchronous of very big proportion and other inductive loads at present and do not have the wiring capacitance device, why is it? main cause has the threephase asynchronous starting easily, the 2nd, the three-phase inductive load is worn the capacitor burden, because it be three-phase 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 alternating-current motor and other inductive loads not charged container that dispatches from the factory usually.
The purpose of this utility model provides a kind of capacitor that can assemble easily, and is used for the three-phase inductive load with capacity capacitor at present and compares, and can dwindle the capacitor volume and reduce cost.
In order to achieve the above object, it is a kind of three-in-one capacitor of fundamental mode that the utility model has adopted with the capacitor of conventional two-plate, this capacitor be with 3 o'clock conventional two-plate capacitors combine become a multiterminal head so that the capacitor of installing.This capacitor has two kinds of compound modes: a kind of is that three pairs of identical pole plates of area are made a non-disconnectable three-phase capacitor; Not a kind of is three capacitors that manufacture certain size, gets up to become disconnectable three-phase capacitor with a casing device.
The advantage of the three-in-one motor capacitor of the utility model is simple in structure, and the technology production of available present production capacitor is easy for installation, is used for three-phase load with conventional electric capacity and compares, and overall volume is little, and product cost is low.Adaptability is strong, does the supporting purpose that reaches local compensation of three-phase inductive load, also can use as conventional two-plate capacitor.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the non-disconnectable capacitor arrangement figure of the three-in-one motor of the utility model.
Fig. 2 is that the three-in-one motor of the utility model can change the capacitor vertical view.
By Fig. 1,21 is capacitor, 2 leading-out terminals, the 3rd as can be seen, shell body, the 4th, and fixing hole, and can find out that thus this three-in-one motor capacitor all has a plurality of line ends.
This capacitor is that three pairs of capacitor plates are made a multi-thread end capacitor as seen from Figure 1, so this capacitor can star connection, also can the dihedral connection, because of it is specially adapted to threephase motor, make the supporting capacitor of compensation usefulness.
Capacitor 1 has three all to be contained in 3 li of housings as seen from Figure 2, because being three capacitors, it forms, therefore it can be adapted to three-phase star connection and dihedral connection, and can find out that by Fig. 2 B the overall dimensions B of this capacitor is 1/2nd of L, so that the adjusting during actual wearing.
Claims (2)
1, a kind of three-in-one motor capacitor, it is three pairs of conventional two-plate capacitors to be combined become a capacitor, it is characterized in that this capacitor has a plurality of line end heads (2).
