Abstract
The utility model relates to the technical field of power transmission, and concretely relates to an anti-drop fixing frame for a high-altitude 330kV power transmission line V-shaped insulator chain. The anti-drop fixing frame of the utility model is characterized in that: a lower end portion of the insulator chain is provided with a ring-shaped metal fitting which is in ring-ring connection with a U-shaped hanging ring fixed on a connecting plate, and the connecting plate is fixedly connected with a wire clamp of a power transmission line. The anti-drop fixing frame of the utility model changes a currently used ball socket connection way of the power transmission line V-shaped insulator chain into the ring-ring connection way between the ring-shaped metal fitting and the U-shaped hanging ring, so as to avoid the problem that a ball head drops from a socket hanging plate under the impact of a strong wind due to the ball socket connection of the V-shaped insulator chain. According to the anti-drop fixing frame of the utility model, a ring-ring interlocking connection way is adopted between the ring-shaped metal fitting and the U-shaped hanging ring, so that the V-shaped insulator chain can be connected stably and firmly; in addition, the anti-drop fixing frame also has the advantages of simple structure, raw material saving, capacity for not increasing line cost, simple and easy construction, and capacity for ensuring safe and stable operation of the power transmission line.
Description
Technical field
The utility model relates to the technology of transmission of electricity field, specifically relates to a kind of high height above sea level 330kV transmission line V-type insulator string slip-off preventing fixed mount.
Background technology
At present, the connected mode of the high height above sea level 330kV transmission line V-type insulator string ball-and-socket connected mode that mainly adopts the ball gold utensil to link to each other with socket-clevis eye.After the V-type composite insulator string was subjected to horizontal phoenix power, the composite insulator bulb impacted the R pin in the bowl head, and after the R pin was subjected to the cross force distortion, bulb came off from socket-clevis eye, the safe and stable operation of serious threat transmission line.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that exists for prior art, and a kind of high height above sea level 330KV transmission line V-type insulator string slip-off preventing fixed mount is provided.
A kind of high height above sea level 330kV transmission line V-type insulator string slip-off preventing fixed mount of the utility model is achieved by following technical proposals: a kind of high height above sea level 330kV transmission line V-type insulator string slip-off preventing fixed mount comprises insulator string, annular gold utensil, U-shaped link, connecting plate, U-shaped link ring ring on described insulator string bottom arranges annular gold utensil and is fixed on connecting plate is connected, and connecting plate is fixedly connected with the wire clamp of transmission line.
A kind of high height above sea level 330kV transmission line V-type insulator string slip-off preventing fixed mount of the utility model has following beneficial effect compared with prior art: the ball-and-socket connected mode of the transmission line V-type insulator string that the utility model will use at present changes the ring ring ring connected mode of annular gold utensil and U-shaped link into, has avoided impacting the problem that lower bulb comes off because V-type insulator string ball-and-socket is connected to strong wind from socket-clevis eye in the prior art.Annular gold utensil of the present utility model and U-shaped link adopt connected mode all linked with one another to make V-type insulator string stable connection firm, and simple in structure, save material, and do not increase line cost, and it is simple to construct, and has guaranteed the transmission line safe and stable operation.
