The utility model discloses owing to move the end at the vacuum bubble and directly with the end overlap joint of flexible coupling, left out the copper billet in the current connection, and the vacuum bubble moves end and flexible coupling plane contact, electric conductive property is good, has improved vacuum load switch's security performance, has advantages such as rational in infrastructure, safe and reliable.
Description
Technical field
The utility model discloses a kind of vacuum load switch improvement structure that is flexible coupling, and divides by International Patent Classification (IPC) (IPC) to belong to vacuum load switch manufacturing technology field.
Background technology
On-load switch is a kind of device for switching that can cut off rated load electric current and certain overload current; Can separate high voltage load switch and low-voltage load switch, wherein vacuum load switch is a kind of high voltage load switch, utilizes vacuum medium arc extinguishing; Electric life is long; Existing vacuum load switch is through the contact of isolation switch and fixed contact or separate and realize that circuit is connected or cuts off, and isolation switch and vacuum bubbles electrically connect, and the moved end of vacuum bubbles is through a centre copper billet and be flexible coupling and connect in proper order with outlet copper; Because vacuum load switch is to utilize the vacuum extinction principle to realize overload and short trouble defencive function on the circuit; And the coupling components of vacuum bubbles moved end is redundant, causes the circuit coupling reliability to reduce, and then has influence on the general safety performance of switch.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable vacuum load switch improvement structure that is flexible coupling.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of vacuum load switch improvement structure that is flexible coupling; Comprise vacuum bubbles, insulating base, be flexible coupling and the outlet copper bar that vacuum bubbles is arranged in the insulating base, the insulating base lateral opening; The vacuum bubbles moved end directly is connected with the end face that is flexible coupling, and being flexible coupling in addition, end is connected in the outlet copper bar.
Further, described to be flexible coupling be to be superposed to one by some copper sheets, and being flexible coupling is connected in the screw that outlet copper bar top cooperates through fixed head and bolt.
Further, the horizontal plane and to extending below of being flexible coupling is passed in described vacuum bubbles moved end, is flexible coupling outwards to form arc structure and to extending below, extend end face and vertical outlet copper bar and electrically connect.
The utility model is owing to directly overlap with the end face that is flexible coupling in the vacuum bubbles moved end; Omitted the copper billet in the existing connection, and the vacuum bubbles moved end and the plane contact that is flexible coupling, conduct electricity very well; Improve the security performance of vacuum load switch, had advantages such as rational in infrastructure, safe and reliable.
