Abstract
The utility model relates to an insulating cylinder for an indoor high-voltage vacuum circuit breaker. Conductive seats for incoming and outgoing lines are respectively installed on the top part and the middle part of the insulating cylinder, wherein a seat (3) for the outgoing lines, which is arranged on the top part is fixedly connected with the static end (4) of an arc-extinguishing chamber through an upper bracket (2); a lower seat (6) for the outgoing lines, which is installed on the middle part is in sliding connection with a conductive rod at the moveable end of a vacuum arc-extinguishing chamber through a lower bracket (8) and a conductive vane (7); the inner side and the outer side of the insulating cylinder are respectively and additionally provided with skirt edge structures (10) and (9) to enable insulating creep distances to be more than 240 mm. The utility model is a novel insulating support; through the utility model, the conductive seats for the outgoing lines can be reliably connected with the arc-extinguishing chamber into a whole, and foreign matters and dust can be prevented from entering.
Description
The insulating cylinder that relevant indoor high-voltage vacuum circuit breaker such as mode and insulation property is used is formed in the installation that the utility model relates to a kind of and vacuum circuit breaker body.
Existing indoor high-voltage vacuum circuit breaker generally adopts the form that fixes installation by insulator, support, supplemental support when vacuum interrupter is installed arranging, exist volume big, influence deficiency such as outward appearance.
The purpose of this utility model is the deficiency at above-mentioned existence, propose a kind of brand-new insulation and support, conduction outlet seat and arc control device can be connected reliably in aggregatesly by it, and it can prevent to lead thing and dust enters, satisfy the requirement of national standard to creep distance
Technical solution of the present utility model: structure as shown in drawings.
Turnover line conductive seat is equipped with at the top of insulating cylinder and middle part respectively, outlet seat (3) is by upper bracket (2) and the quiet end of arc control device (4) fixed connection on the top, the following outlet seat (6) that install at the middle part slides with vacuum interrupter moved end conducting rod (5) by lower carriage (8), conductive vanes (7) and connects, and inside and outsidely all is equipped with shirt rim structure (10) at insulating cylinder, (9) make inside and outside insulation creep distance all more than 240mm.Insulating cylinder is equipped with the wedge shape projection as supplemental support (11) over against the side that outlet seat circular hole is installed, and insulating cylinder and circuit breaker frame connect with screw.This insulating cylinder is the main support of circuit breaker galvanic circle body part.Can change traditional galvanic circle by it and install and fix mode, promptly be fixed on the mounting bracket by insulator on insulator, install again, the traditional approach of lower carriage, its superiority is to make installation more convenient, each alternate consistency of circuit breaker is better, and has improved the outward appearance of this part greatly.It is that a kind of brand-new insulation is supported; can reliably connect in aggregates with arc control device conduction outlet seat by it; simultaneously can also protect arc control device to avoid impact damage; acquisition is as the heat loss through convection effect of chimney; and it can prevent that foreign matter and dust from entering; make arc control device ceramic package surface be difficult for being subjected to filthy contamination by dust, its insulation property satisfy the requirement of national standard to creep distance.
Accompanying drawing is a structural representation of the present utility model.
Insulating cylinder adopts the epoxy injection moulding process, than the compressing worker of traditional SMC (CDNC) Skill has higher dimensional accuracy, mechanical strength and good electrical property, and the design of supplemental support makes insulating cylinder When breaker work moves, have better intensity and shock resistance, bending resistance.
Claims (2)
1. the insulating cylinder of indoor high-voltage vacuum circuit breaker, turnover line conductive seat is equipped with at the top and the middle part that it is characterized in that insulating cylinder respectively, outlet seat (3) is by upper bracket (2) and the quiet end of arc control device (4) fixed connection on the top, the following outlet seat (6) that install at the middle part slides with vacuum interrupter moved end conducting rod (5) by lower carriage (8), conductive vanes (7) and connects, in inside and outside shirt rim structure (10), (9) of all being equipped with of insulating cylinder, make inside and outside insulation creep distance all more than 240mm.
2, the insulating cylinder of indoor high-voltage vacuum circuit breaker according to claim 1 is characterized in that insulating cylinder over against the side that outlet seat circular hole is installed, and insulating cylinder and circuit breaker frame connect with screw, are equipped with the wedge shape projection as supplemental support (11).
