Abstract
The utility model provides a high-voltage ceramic vacuum switch tube which comprises a movable end component and a static end component, which correspond to each other and are positioned on the same axis. A movable end cover plate and a static end cover plate are arranged inside the movable end component and the static end component respectively; a ceramic case component is connected between the movable end cover plate and the static end cover plate and sleeved outside the movable end component and the static end component; the ceramic case component comprises two corrugated ceramic cases which are connected through a fixing ring and a shielding drum which is nested inside the two corrugated ceramic cases through the fixing ring. The high-voltage ceramic vacuum switch tube is characterized in that sealing rings are welded at the outer ends of the two corrugated ceramic cases through a sealing end housing, the ceramic case component is welded with the movable end cover plate and the static end cover plate through the sealing rings at the two ends thereof, an exhaust pipe is hermetically connected at the outer end of the static conducting rod of the static end component, and an exhaust passage is arranged on the static conducting rod and used for communicating the corrugated ceramic cases with the inner cavity of the exhaust pipe. The high-voltage ceramic vacuum switch tube has the advantages of high vacuum degree, high success rate of high-voltage on/off, high welding strength of the ceramic cases and the sealing rings, good welding air tightness and stable product quality.
Description
Technical field
The utility model is particularly related to a kind of high-voltage ceramic vacuum switch tube that cut-offs.
Background technology
The developing industry of the national most important thing is already classified resource equipment as in China's science and technology development planning at present, proposition develops to high voltage, extra-high pressure vacuum circuit-breaker direction, this is that equipment for power transmission and distribution manufacturing industry technology is further challenged, and provides fabulous opportunity for the manufacturing technical development of grid equipment especially.
Existing high-voltage ceramic vacuum switch tube is to be made of moved end assembly, quiet end assembly, the porcelain shell component that is sleeved on moved end assembly and quiet end assembly outside, the porcelain shell in its porcelain shell component directly with moved end assembly and quiet end assembly in sealing ring weld.The problem of its existence is: the vacuum degree in the vacuum switch tube is low, can not effectively guarantee the success rate that high pressure cut-offs; Direct and the sealing ring welding of porcelain shell, weld strength is low, and welding airtightness is poor, and the commissure is easy to generate chronic leakage, causes high pressure to cut-off failure, causes various accidents.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can guarantee condition of high vacuum degree, thereby guarantees the success rate height that high pressure cut-offs, and porcelain shell and sealing ring weld strength height, welding airtightness are good, the high-voltage ceramic vacuum switch tube of constant product quality.
The utility model is achieved in that it comprises mutual correspondence and is positioned at moved end assembly and quiet end assembly on the same axis, in moved end assembly and quiet end assembly, be respectively equipped with moved end cover plate and quiet end casing, between moved end cover plate and quiet end casing, be connected with the porcelain shell component that is enclosed within moved end assembly and quiet end assembly outside, porcelain shell component comprises two ripple porcelain shells connecting by retainer ring and is nested in two shielding cylinders in the ripple porcelain shell by described retainer ring, its special character is: sealing ring is welded by a sealing-in end shield respectively in the outer end at two ripple porcelain shells, described porcelain shell component welds with moved end cover plate and quiet end casing respectively by the sealing ring at its two ends, static conductive rod outer end at quiet end assembly is sealedly connected with blast pipe, is provided with the exhaust passage that is communicated with ripple porcelain shell and blast pipe inner chamber on described static conductive rod.
Above-mentioned high-voltage ceramic vacuum switch tube is with the insulation gum cover respectively in sealing ring and two ripple porcelain shell outer ends at porcelain shell component two ends.
Above-mentioned high-voltage ceramic vacuum switch tube, described sealing ring material is a stainless steel.
The utility model has the advantages that: owing to be sealedly connected with blast pipe in the static conductive rod outer end of quiet end assembly, can utilize blast pipe to realize long-time high-temperature exhaust air, make the abundant emptying of gas in the vacuum switch tube, can guarantee the condition of high vacuum degree in the vacuum switch tube, thereby guarantee the success rate height that high pressure cut-offs; Owing to weld sealing ring by the sealing-in end shield respectively in the outer end of ripple porcelain shell, make the weld strength height of ripple porcelain shell and sealing ring, welding airtightness good, constant product quality, the high pressure connecting-disconnecting function is strong, long service life.
