Abstract
The invention relates to a combined electrode column of a vacuum arc extinguishing chamber which overcomes the problems of lower flow capacity and weaker heat radiating capability which may seriously reach the vitrification temperature of epoxy resin to cause major accidents in the traditional sealing electrode column. The combined electrode column is characterized in that epoxy resin perfusion points are arranged in the mutual connecting positions of an upper shielding ring, an upper insulating barrel, an upper wire outlet end, a lower insulating barrel and a shielding electrode; pre-mixed epoxy resin and a solidifying agent are perfused for firmly connecting the shielding electrode, the lower insulating barrel, the upper wire outlet end, the upper insulating barrel and the upper shielding ring together to form an outer cover of the electrode column; the vacuum arc extinguishing chamber is assembled in the outer cover of the electrode column; and the conductive connection of the electrode column is realized through a movable contact, a spring touching finger and a lower wire outlet end. The combined electrode column has the advantages that the manufacturing technology of the electrode column is simplified; the insulating capability of the electrode column is enhanced; the manufacturing cost of the electrode column is reduced; once the vacuum arc extinguishing chamber self hasa quality problem, only the vacuum arc extinguishing chamber needs replacing; an outer electrode column still can be used continuously; and therefore, the installation and the replacement of the vacuum arc extinguishing chamber are convenient.

Technical field
The invention belongs to high voltage electrical apparatus technical field, particularly for a kind of composite type vacuum interrupter pole in the 126kV high-voltage system vacuum circuit-breaker.
Background technology
In the prior art; the vacuum interrupter pole is pole normally; adopt the APG(automatic pressure gel) the technology making; need special-purpose automatic pressure gel mould and the vacuum blender of several covers like this; make-up machine; special equipments such as heated at constant temperature case are solidified in the back; the pole that completes also must carry out the x-ray fluoroscopy inspection; to determine whether defectiveness of inside; therefore; the investment of mould and equipment is bigger; production cycle is longer; particularly x-ray fluoroscopy inspection; need special-purpose high-power X-ray machine; price is very high; also need special-purpose plumbous room and labour protection measures simultaneously; admittedly in case quality problems occur in the envelope process, not only the epoxy resin of pole and silicon gel part need be broken into pieces and scrap, even expensive vacuum interrupter also might be scrapped simultaneously together; therefore the production difficulty is bigger; along with the raising of electric pressure, the vacuum extinction chamber size constantly strengthens, and manufacture difficulty is also in continuous increasing; cost is more and more higher; in addition, because vacuum interrupter is enclosed in epoxy package inside fully admittedly, through-current capability is lower; heat-sinking capability a little less than; the temperature rise of pole is higher, may reach the vitrification point of epoxy resin when serious, causes bigger accident.
Summary of the invention
Problem to be solved by this invention is, overcome the weak point that prior art exists, the manufacturing process that can simplify pole is provided, reduce the cost of manufacture of pole, be conducive to simultaneously breaker mechanic property adjustment be used for a kind of composite type vacuum interrupter pole in the 126kV high-voltage system vacuum circuit-breaker.
The technical solution used in the present invention comprises bucking electrode, following insulating cylinder, last leading-out terminal, last insulating cylinder and last shading ring and mounting flange, be provided with first epoxy resin perfusion point at last shading ring and the interconnective position of last insulating cylinder, be provided with second epoxy resin perfusion point at last insulating cylinder and the interconnective position of last leading-out terminal, be provided with the 3rd epoxy resin perfusion point at last leading-out terminal and the interconnective position of following insulating cylinder, be provided with Fourth Ring epoxy resins perfusion point at following insulating cylinder and the interconnective position of bucking electrode, at described first epoxy resin perfusion point, second epoxy resin perfusion point, inject pre-mixed epoxy resin and curing agent in the 3rd epoxy resin perfusion point and the Fourth Ring epoxy resins perfusion point, with bucking electrode, following insulating cylinder, last leading-out terminal, last insulating cylinder and last shading ring firmly link together and constitute the pole outer cover, in the pole outer cover, assemble vacuum interrupter, and by moving contact, spring touch finger realizes that with lower wire end the conduction of pole is connected.
Described first epoxy resin perfusion point, second epoxy resin perfusion point, the 3rd epoxy resin perfusion point and Fourth Ring epoxy resins perfusion point respectively are processed with two material feeding circular holes by two ring-shaped grooves compositions on each ring-shaped groove.
Compare with existing traditional pole, the invention has the beneficial effects as follows:
(1) described pole is modular construction, connect electric conductor, insulating cylinder, bucking electrode with the epoxy resin perfusion, replaced traditional employing automatic pressure gelation process to make pole, simplified the manufacture craft of pole, and improved the insulating capacity of pole, needing also to avoid the investment on particular manufacturing craft, special-purpose making apparatus and the special testing instrument, reduced the cost of manufacture of pole;
(2) described epoxy resin is poured in batch mixing in the air, the needing no vacuum operation, the perfusion of resin only needs simple injection tool to finish, and solidify at normal temperatures, need not firing equipment, and the epoxy resin that connects usefulness is fully within the shield ranges of electrode, and internal defects can not influence the insulation property (office puts, power frequency or impact) of pole, therefore need not to carry out the x-ray fluoroscopy inspection.
(3) described vacuum interrupter changes package assembly into by solid seal structure, vacuum interrupter assembles in pole, flexible, in case self quality problems appear in vacuum interrupter, only needing to change vacuum interrupter gets final product, outside pole still can continue to use, therefore and installation and the replacing of vacuum interrupter have been made things convenient for, it is the stronger sulfur hexafluoride gas of capacity of heat transmission between vacuum interrupter and insulating cylinder, improve the radiating condition of pole, be conducive to convection current and heat conducting and radiating, reduced the temperature rise of pole, improve the ampacity of pole, make the equipment operation safer.
(4) the described shape that goes up lower wire end and electric field shielding electrode and position equilibrium lower wire end and go up electric field between the mounting flange of leading-out terminal and ground connection on the arc control device, in assurance conductor ampacity, guaranteed alternate and relatively between dielectric strength.
The present invention makes pole with the 126kV vacuum interrupter for the first time and is installed on the 126kV C-GIS product, and through tentative use, mechanical strength is higher than the requirement of product dynamic thermal stability, and dielectric strength satisfies request of national standard.
