Abstract
The utility model belongs to a high voltage electricity transmission and distribution device which relates to a single phase isolating switch. The single phase isolating switch comprises a frame and a front static contact head and a back static contact head which are fixed respectively on the front end and the back end of the frame by insulators, wherein the structure of the front static contact head comprises a horizontal front wire connecting terminal and two upright front contact head plates, which are connected into integration; the structure of the back static contact head comprises a horizontal back wire connecting terminal and two upright back contact head plates, which are connected into integration; two sets of movable contact knives are installed between the front static contact head and the back static contact head, the back ends of the two sets of movable contact knives are respectively hinged with the two back contact head plate of the back static contact head, contact pieces on the front ends of the two sets of movable contact knives are respectively corresponding to the positions of the two front contact head plates of the front static contact head forming a switch contact; the middle part of the frame is provided with a transversal rotary shaft of which the middle part is fixed with a crank arm which is connected with the movable contact knives by being hinged with an insulating pulling rod. The utility model has the advantages of compact structure, simple transmission and convenient installation and adjustment.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of single-phase isolating switch.
Background technology
Common single-phase isolating switch generally is by a pair of fixed contact and is installed in a movable touch knife between two fixed contacts, and the operating mechanism of movable touch knife is formed, owing to will guarantee that enough contacts area and contact pressure are arranged between movable touch knife and fixed contact, thereby fixed contact and movable touch knife often volume is bigger, taking up room of whole switch is also bigger, its transmission link is more simultaneously, assembling and adjustment inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of compact conformation, transmission are simple, installation and single-phase isolating switch easy to adjust.
Single-phase isolating switch of the present utility model includes a framework and is fixed on the preceding fixed contact and the back fixed contact at the forward and backward two ends of framework by insulator; The structure of fixed contact includes preceding binding post and two vertical front contact plates of the level that is connected as a single entity before described, and the structure of back fixed contact then includes back binding post and two vertical back contact plate of a level that is connected as a single entity; Two groups of movable touch knifes are installed between forward and backward fixed contact, and each group movable touch knife is made up of contact side by side some, and each contact of organizing movable touch knife is connected as a single entity by a contiguous block; The rear end of two groups of movable touch knifes respectively with back two of fixed contact after contact plate hinged, the contact of two groups of movable touch knife front ends is then corresponding with two front contact Board positions of preceding fixed contact respectively, constitutes switch contact; In frame mid portion a horizontal rotating shaft is installed, the rotating shaft middle part is fixed with connecting lever, and connecting lever is connected with movable touch knife by hinged insulated tension pole.
The utility model can be adjusted separately contact each owing to adopt two groups of contact knifes and many structures to contact, is easy to guarantee contact pressure and contact area, simultaneously few, the compact conformation of its drive disk assembly, reliable in action height.
