Abstract
The utility model discloses a solid seal full-vacuum switching device, which comprises a three-station vacuum switching chamber which is arranged on the right side of a vacuum arc distinguishing chamber below a casing and is parallel to the vacuum arc distinguishing chamber. The lower portion of a three-station vacuum switching chamber driving rod is fixedly connected with a moving contact at the upper end of the three-station vacuum switching chamber. The moving contact of the three-station vacuum switching chamber is opposite to a fixed contact on the lower portion of the three-station vacuum switching chamber and opposite to a grounding contact above the moving contact. An outer end of the grounding contact is connected with a grounding bus, and electric conducting soft connection is adopted between the moving contact of the three-station switching chamber and a moving contact of the vacuum arc distinguishing chamber in a cavity above the three-station vacuum switching chamber and a moving contact of the vacuum arc distinguishing chamber. Compared with the prior art, the solid seal full-vacuum switching device has the remarkable advantages that the volume is small and a wiring mode is changed conveniently and fast.
Description
Technical field:
The utility model relates to a kind of high voltage switching device, particularly a kind of vacuum switching device that seals admittedly.
Background technology:
The sulfur hexafluoride gas switch cubicle has advantages such as little, the non-maintaining and anti-environment of volume is good, the operation occasion that is specially adapted to have relatively high expectations.But one of sulphur hexafluoride greenhouse gas that to be Kyodo Protocol clear and definite belong to the gas that restriction is used.For replacing the sulphur hexafloride circuit breaker cabinet, become the important topic of various countries' research.The solid insulation switch cabinet is a kind of novel electric equipment that adopts solid insulating material that each electric elements in the cabinet are encapsulated; But because the electric elements kind is many; And components and parts have nothing in common with each other; Need with single or a plurality of elements respectively solid encapsulation become various modules, like vacuum extinction module, earthed switch module, isolating switch module, busbar modules, fuse module etc., each module generally is a three-phase split-phase type structure.Wherein vacuum interrupter, earthed switch and isolating switch are core parts; The combined level of its module and determined the shape and the volume of solid insulation switch cabinet with the draw bail of other modules; And existing structure makes two even three separate modules with vacuum interrupter, earthed switch and isolating switch; Bulky, installation form immutable (single) is unfavorable for the miniaturization of switch cubicle.
Summary of the invention:
The purpose of the utility model provides the little and a kind of easily and efficiently vacuum switching device that seals admittedly of mode of connection change of a kind of volume.The technical solution of the utility model is; Comprise three station vacuum interrupter chambers; It is characterized in that: the right side of vacuum interrupter is provided with the three station vacuum interrupter chambers that vacuum interrupter therewith parallels below housing; The moving contact of the bottom of three station vacuum interrupter chamber drive rods and three station vacuum interrupter chambers upper end is connected; The moving contact of this three stations vacuum interrupter chamber therewith the fixed contact of three station vacuum interrupter chamber bottoms relatively and therewith the grounding contact of moving contact top is relative; The outer end of this grounding contact connects with earth bus, is provided with the soft connection of conduction between three-station chamber moving contact above three station vacuum interrupter chambers and vacuum interrupter in the cavity and the vacuum interrupter moving contact.A kind of vacuum switching device that seals admittedly; Comprise three station vacuum interrupter chambers; It is characterized in that: the left side of vacuum interrupter is provided with the three station vacuum interrupter chambers that vacuum interrupter therewith parallels below housing; The moving contact of the bottom of three station vacuum interrupter chamber drive rods and three station vacuum interrupter chambers upper end is connected; The moving contact of this three stations vacuum interrupter chamber therewith the fixed contact of three station vacuum interrupter chamber bottoms relatively and therewith the grounding contact of moving contact top is relative; The outer end of this grounding contact connects with earth bus, is provided with the soft connection of conduction between three-station chamber moving contact in the cavity above three station vacuum interrupter chambers and vacuum interrupter and the vacuum interrupter moving contact.The utility model and prior art relatively have that volume is little to change remarkable advantage easily and efficiently with the mode of connection.
