Abstract
The utility model discloses a capacitor element structure, which comprises an element body, insulating liners and lead sheets. The element body consists of a pole plate and a medium layer, the liners are positioned on an inner layer of the element body, the liners and the element body are jointly rolled into a flat barrel, the two lead sheets are disposed among the liners and the inner layer of the element body and led out of one end of the element body, and the liners form linings with flat elliptical sections in the center of the element body. The two liners are arranged between the two opposite lead sheets, the liners are protruded out of the end surface of the element body at one end, which is inserted with the lead sheets, of the element body, and the insulation distance between the lead sheets is effectively guaranteed. Parameters of the pole plate, media and the liners are set and the position of a lead plate is calculated during manufacture. The lead sheets and the liners can be placed and rolled automatically by a rolling machine. By the aid of the capacitor element structure, production efficiency is improved, damage to the media and the pole plate due to artificial factors is avoided, and rolling quality is guaranteed. In addition, the liners are high in universality, processing procedures of the liners are reduced, the liners form the linings so that the element body is 'harder' and can be carried and pressed conveniently, and dead wrinkle is not easy to be caused.
Description
(1) technical field
The utility model relates to the power capacitor technical field, is specially a kind of structure of capacitor element.
(2) background technology
Coupling capacitor and capacitor voltage divider mainly are made of through the metal dilator that fuse, insulating oil and the compensation oil volume of high vacuum impregnation process varies with temperature usefulness insulator shell, interior dress.Fuse is made up of the element connected in series of some capacitors.The element body that the element of capacitor is made of dielectric and pole plate is reeled to flatten and is formed.Pole plate is drawn by lead wire, adds the cushions to realize the insulation of lead wire between two lead wire.Insulation between the element guarantees by the outsourcing medium.
The component structure of existing capacitor is that the element body volume that dielectric layer and pole plate constitute flattens shaping again for tubular, and two lead wire that accompany liner are inserted between pole plate and the medium.
The shortcoming of this component structure is: 1, the element body of dielectric layer and the pole plate formation process that rolls needs closed-down manual to place the lead wire that accompanies liner, is difficult to use the higher bushing machine of automaticity to roll element; 2, damage medium and pole plate in liner and the lead wire put procedure easily, influence rolls the element quality that forms; 3, need increase manufacturing process according to the pre-processed corresponding liner of component size; 4, the capacitor element integral body of this kind component structure is softer, and easy formation fold in carrying and fuse press-fit becomes capacitor element puncture hidden danger in service; When 5, element flattens, form dead folding easily, damage medium or pole plate.
(3) utility model content
The purpose of this utility model provides a kind of structure of capacitor element, and internal layer one roll set that liner is in the element body of pole plate, dielectric layer formation is a flat drum shape, and two lead wire place between liner and the element body internal layer.Make things convenient for rolling automatically of capacitor element, and improve element quality.
The structure of the capacitor element of the utility model design, comprise the element body that pole plate, dielectric layer constitute, insulating cell and 2 lead wire, pole plate and dielectric layer are wound into the cylindrical component main body that the cross section is flat ellipse, 2 lead wire are joined with corresponding pole plate respectively, end at element body is drawn lead-in wire, between 2 lead wire insulating cell is arranged; It is characterized in that liner is in the internal layer of the element body of pole plate, dielectric layer formation, be flat tube with pole plate, the common volume of dielectric layer, two lead wire place between liner and the element body internal layer; Liner is formed centrally the liner that the cross section is a flat ellipse in element body.Two lead wire relatively, between be 2 layers of liner.
An end liner pad that is inserted with lead wire at element body protrudes the element body end face, and preferred plan is that liner protrudes element body end face 5mm～30mm, with the creepage distance between two lead wire of effective assurance element.
Capacitor element of the present utility model is before rolling, setting rolls the length of the internal diameter calculating liner of element, according to the internal diameter that rolls element and the number of total coils calculating that rolls and the length of setting pole plate and dielectric layer, calculate the length of outsourcing insulation according to the external diameter that rolls element; Set their transmission order; Medium, pole plate and liner predetermined fixed are on the mandrel of bushing machine, and a side of the liner of predetermined fixed protrudes from medium, the pole plate with side; Set to place the number of turns of lead wire, one of them lead wire is positioned on the position of the corresponding setting number of turns of pole plate layer length, another lead wire place previous lead wire rear and with previous distance another pole plate layer for the length of this layer half-turn on; Bushing machine carries out element automatically and rolls.After element rolled and finishes, liner had formed liner in capacitor element inside, two lead wire relatively, between insulate for double layer cushion.
The advantage of the structure of the utility model capacitor element is: 1, when element rolls, the parameter of pole plate, medium and liner, lead plate is set by the Element Technology requirement; The higher bushing machine of automaticity can be realized rolling automatically, places lead wire and liner automatically, improves the production efficiency of capacitor greatly; 2, the automatic placement of lead wire and liner, the damage to medium and pole plate of having avoided human factor to cause has guaranteed the manufacturing quality of capacitor element; 3, liner highly versatile need not to prepare various gasket by all types of capacitor elements, has reduced the manufacturing procedure of liner; 4, liner has formed a liner that the cross section is a flat ellipse in the capacitor element body interior, makes element " firmly ", is convenient to the carrying of element and press-fits; 5, because the liner of liner is arranged, element is not prone to dead folding when flattening, and pole plate and dielectric layer be easy damaged not.
