Abstract
The utility model belongs to the technical field of switches, and relates to a high-voltage AC single-phase isolating switch movable blade. The high-voltage AC single-phase isolating switch is provided with a cylindrical or cuboid-shaped movable blade arm made of a copper rod, two ends of the movable blade arm are both provided with a flat head, the flat head is provided with a mounting hole, one end of the flat head is provided with a copper flexible connector, and the other end of the flat head is provided with a moving contact. According to the utility model, the movable blade arm of the movable blade is integrally prepared by adopting the copper rod with good conductivity, the two ends of the movable blade arm are connected to the copper flexible connector and the moving contact respectively, thereby well solving problems of inaccurate positioning in closing operation and short service life because an existing movable blade is easily heated and deformed in the use. The high-voltage AC single-phase isolating switch movable blade has the advantages of simple structure, high strength, good guidance, high electric conduction, heat conduction and corrosion resistance and excellent electrical performance, and greatly prolongs the service life of the movable blade.
Description
Technical field
The utility model belongs to switching technique field, particularly a kind of high-voltage alternating single-phase isolating switch cutting blade.
Background technology
Current electrical apparatus industry, the major loop cutting blade great majority of isolating switch adopt two blades to fasten by bolt clip, then are connected with the dynamic and static contact of isolating switch, realize separating brake, the closing operation of isolating switch.Because isolating switch is in long-term work process, blade contacts, rubs with moving contact, causes surface abrasion, thereby cause blade heating, distortion, finally cause the location of closing a floodgate inaccurate, destroyed the electric property of isolating switch, greatly shortened the useful life of isolating switch.
Summary of the invention
The purpose of this utility model is exactly inaccurate in order to overcome existing isolating switch cutting blade combined floodgate location, and the problem that electric property is poor and useful life is short, provides a kind of high-voltage alternating single-phase isolating switch cutting blade.
Concrete scheme of the present utility model is: high voltage isolator cutting blade, it has the cylindrical or cuboid moving knife arm of being made by red copper bar, moving knife arm two ends are respectively processed with a flat head, on described flat head, be processed with installing hole, wherein on the flat head of one end, red copper is installed and is flexible coupling, on other end flat head, moving contact is installed.
Good for guaranteeing moving knife arm conductivity, the arm of moving knife described in the utility model is cylindrical, and its diameter is 20～40mm; Certainly moving knife arm can be also cuboid, and the cross section of cuboid is square, and its length of side is 20～40mm.
Better, more solid and reliable for guaranteeing cutting blade conductivity, flat-nosed thickness described in the utility model is 10～12mm, and flat head is designed to arc transition with the connecting portion of moving knife arm and is connected.
In order to make, cutting blade closes a floodgate, separating brake motion action is easy, the utility model is processed with a circular hole at described moving knife arm middle part, on circular hole, composite insulated pull-rod can be installed, be connected with the operating mechanism on main conductive circuit holder, coordinate separating brake, closing operation.
The utility model has changed cutting blade in existing isolating switch and has adopted two blades to fasten by bolt clip, the blade distortion of easily generating heat in long-term use, causing closing a floodgate, it is inaccurate to locate, affect the problem in its life-span, adopt the good red copper bar of conductivity to be integrated into moving knife arm cutting blade, at the two ends of moving knife arm, install respectively that red copper is flexible coupling and moving contact, well solved the existing cutting blade problem that location is inaccurate, useful life is short of closing a floodgate; The utility model is simple in structure, and intensity is high, guidance quality good, conduction, heat conduction, corrosion resistance are strong, and excellent electrical properties has extended useful life of cutting blade greatly.
