Abstract
The utility model discloses a low-voltage large-open circuit ceramic vacuum switch tube with strong current opening and closing ability, small contact resistance and welding resistance. The low-voltage large-open circuit ceramic vacuum switch tube comprises a moving end tube core and a static end tube core, which are correspondingly and coaxially arranged; a moving end contact and a static end contact are respectively arranged at the opposite ends of the moving end tube core and the static end tube core; ceramic insulating housings are sleeved on the moving end tube core and the static end tube core; two ends of the ceramic insulating housings are excessively and fixedly connected with a moving end cover board and a static end cover board through a copper sealing ring; and shielding barrels sleeved outside the moving end contact and the static end contact are nested inside the ceramic insulating housings. The low-voltage large-open circuit ceramic vacuum switch tube is characterized in that the moving end contact and the static end contact are of a composite transverse magnetic field structure, and respectively welded with a moving contact sheet, a moving contact support, a static contact sheet and a static contact support, which are evenly distributed inside four grooves shaped like a Chinese character 'wan'; the moving contact sheet and the static contact sheet adopt a CuCr40Ti alloy material; the moving contact support and the static contact support adopt a TU1 material; a moving shield plate is welded above the moving contact support, and a static shield plate is welded below the static contact support.
Description
Technical field
The utility model relates to a kind of ceramic vacuum switch pipe, particularly a kind of low-voltage big-breaking capacity ceramic vacuum switch tube.
Background technology
Vacuum switch tube is the key components of vacuum switch (circuit breaker, contactor, on-load switch etc.), the national economy every profession and trades such as electric power, metallurgy, machinery, mine, traffic, scientific research, industry, agricultural have been widely used in, have that volume is little, lightweight, the life-span is long, dependability is high and the remarkable advantage such as easy to maintenance, become the direction of domestic and international switch industry development and application.The development of colliery industry is the important foundation of national development, and the safety in production of the sector is most important.The colliery is the short circuit current connecting-disconnecting function with its key parameter of vacuum switch tube.Its structure of contact terminal of ceramic vacuum switch pipe of producing at present is the vertical magnetic structure of contact terminal of cup-shaped, and dynamic and static contact resistance is large, large short circuit current easily occurs cut-off or close contact welding problems when closing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly cut-offs with the making current ability by force, and contact resistance is little, the low-voltage big-breaking capacity ceramic vacuum switch tube of anti-melting welding.
The technical solution adopted in the utility model is; It comprises moved end tube core and the quiet end tube core of mutual correspondence and coaxial arrangement, be respectively equipped with moved end contact and quiet end contact in the opposite end of moved end tube core and quiet end tube core, be arranged with the ceramic insulation shell at moved end tube core and quiet end tube core, the two ends of ceramic insulation shell respectively by the copper sealing ring excessively and moved end cover plate and quiet end casing affixed, be nested with the shielding cylinder that is enclosed within moved end contact and quiet end contact outside at the ceramic insulation shell, its special character is: described moved end contact and quiet end contact are compound transverse magnetic field structure, and be welded by the uniform moving contact sheet of " ten thousand " font four groove and movable contact head rest and fixed contact sheet and stationary contact head rest respectively, described moving, what the fixed contact sheet adopted is the CuCr40Ti alloy material, moving, the stationary contact head rest adopts the TU1 material, above the movable contact head rest, be welded with moving barricade, below the stationary contact head rest, be welded with quiet barricade.
The utility model has the advantages that: because moved end contact and quiet end contact are for strengthening the compound transverse magnetic field structure of high-current on-off, what dynamic and static contact blade adopted is the CuCr40Ti alloy material, strengthened the resistance fusion welding energy of high-current on-off or pass contact when closing, what dynamic and static contact tray adopted is the TU1 material, namely satisfied the intensity of cut-offfing of contact, make again contact resistance little, be welded with barricade above the moving contact with below the fixed contact, shielding during high-current on-off the electric arc splatter to insulation porcelain shell inwall, thereby the raising connecting-disconnecting function.
