Abstract
The utility model relates to an arc-extinguishing chamber assembly of an outdoor vacuum load switch, comprising a vacuum arc-extinguishing chamber, an upper and a lower lead terminals and an insulated tension pole. The utility model is characterized in that the vacuum arc-extinguishing chamber is fixedly sealed in an upper porcelain bushing; the end surfaces of the upper porcelain bushing and a lower porcelain bushing are embeded with connecting bolts; the upper surface and the lower surface of a coupling disk the middle part of which is inlaid with the lower lead terminal (busbar) are provided with slots and holes corresponding to the bolts in the upper porcelain bushing and the lower porcelain bushing; the bolts penetrating through the holes are screwed in the slots by nuts. The utility model can cause the outdoor vacuum load switch to enlarge an external insulation distance and can enlarge a creep distance, which is favorable to the miniaturization of the integral device; the utility model is used on switches of arc-extinguishing devices.
Description
The utility model belongs to the loud-break switch of being with the lonely device that goes out, the particularly arc-control device of outdoor vacuum on-load switch.
The arc-control device of existing outdoor vacuum on-load switch covers one deck silicon rubber outward by arc control device, also has a silicon rubber to support between arc control device and switch casing, connects by ring flange between them.Because the ring flange external diameter, causes distance increasing between each phase of switch greater than arc control device silicon rubber external diameter, is unfavorable for the integral device miniaturization.In addition, arc control device coat the complex process of silicon rubber outward, the production cost height.
The purpose of this utility model is a kind of novel arc control device assembly of design, makes it can strengthen the external insulation distance, adds large distance, and anti-condensation.Help the switch integral miniaturization.
Below, narrate its structure with reference to accompanying drawing.
With insulating cement 3 vacuum interrupter 4 is encapsulated in the insulator 2 admittedly, the lower surface of last insulator 2 is buried bolt 6 equably underground, the upper surface that is positioned at the following insulator 11 on the switch casing is also buried bolt 6 equably underground, the bolt of burying underground in the insulator up and down 6 staggers mutually, link the circumference place of terminal pad 5 upper and lower surfaces of insulator up and down respectively have with insulator up and down in bolt 6 corresponding slotted eyes, the centre of terminal pad 5 is inlaid with down lead terminal (busbar) 9.
Slotted eye on the so-called terminal pad 5 is a groove of opening a depthkeeping (thick) degree along the thickness direction of terminal pad 5, and groove is opening facing to circumferencial direction.The bottom of groove drills through the hole.Bolt 6 passes the back from the hole fastening with nut 8 in groove.
The utility model is owing to be packaged in vacuum interrupter 4 usefulness insulating cements in the insulator 2, insulating cement has suitable temperature coefficient, suitable intensity, not bursting by freezing in serviceability temperature (+40 °～-40 °) scope, not softening, have stronger insulating capacity, and have lower heat conductivility.Therefore can realize strengthening the external insulation distance, add large distance, solve anti-condensation problem simultaneously.In addition, owing to adopt the structure of terminal pad 5, the external diameter of terminal pad 5 is not more than the insulator external diameter, like this, can reduce phase spacing, makes whole switching device miniaturization.
Description of drawings:
Fig. 1 is a full sectional view of the present utility model, and Fig. 2 is the front view of terminal pad 5, and Fig. 3 is the A-A cutaway view of terminal pad 5.
