Abstract
The utility model discloses a rotary isolating switch comprises first insulators, conducting bars, fixed contacts and an insulating driving shaft. The fixed contacts are arranged on the first insulators. The insulating driving shaft is composed of second insulators, conductive metal blocks and a metal shaft, all of which are serially connected at intervals. The conducting bars are installed on the conductive metal blocks. The metal shaft on the insulating driving shaft is rotated to enable the rotation of the whole insulating driving shaft, and the conducting bars and the fixed contacts are driven to be contacted or separated, so that the connection or isolation of the circuit is realized.
Description
Technical field
The utility model relates to device for switching field, in particular to a kind of rotary isolation switch.
Background technology
Existing isolating switch structure is as shown in Figure 1 a, 1 b: it is made up of support 1, supporting insulator 2, static terminal 3, conductive bus bar 4, moved end 5, drive rod 6, compression spring 7.Conductive bus bar 4 rotates along moved end son 5 under the actuating of drive rod 6, in the time of the position of conductive bus bar 4 in contacting with static terminal 3, by conducting between static terminal 3 and moved end 5, thereby connects circuit; When conductive bus bar 4 is when overhead positions (shown in dotted line), will isolation between static terminal 3 and moved end 5, thus point deenergizing; In overall structure, support 1 is basis, and compression spring 7 can keep conductive bus bar 4 and static terminal 3 and moved end 5 to have reliable electrical contact.The shortcoming of this structure is that actuating conductive bus bar 4 rotates and need to realize by drive rod 6, and transmission link is many, and reliability is low.
Utility model content
The utility model provides a kind of rotary isolation switch, rotates in order to overcome actuating conductive bus bar in prior art the problem that transmission link is more, reliability is low needing.
For achieving the above object, the utility model provides a kind of rotary isolation switch, comprise: the first insulator, busbar, fixed contact and insulated drive axis, fixed contact is arranged on the first insulator, insulated drive axis is formed by the second insulator, conducting metal piece and metal shaft interval serial connection, and busbar is arranged on conducting metal piece, makes whole insulated drive axis rotation by the metal shaft on rotating insulated driving shaft, drive busbar with fixed contact contact or separate, realizing connection or the isolation of circuit.
Optionally, the second insulator, conducting metal piece have respectively multiple.
Above-described embodiment is driven busbar with fixed contact contact or is separated by rotating driveshaft, realizes connection or the isolation of circuit, has simplified the transmission link of isolating switch, improves its reliability, both can realize electric three phase isolated, can reach again the object of direct driving.
