The utility model relates to the technical field of overhead line electric power fittings, in particular to a novel overhead line column type insulator fixing device.
Background
The medium-voltage overhead lines of the power system basically adopt pin-type or pillar-type insulator fixed conductors. At present, a cross binding method of an aluminum wire top groove is commonly adopted for needle type or pillar type insulator binding, the binding method has high requirements on the construction process, and the binding wire is ensured not to be subjected to extra mechanical force. With the increase of the power load, the cable wire diameter of the medium voltage circuit design is thicker and thicker, the cable can vibrate along with wind, and the binding wire is subjected to vertical pulling force caused by relief fluctuation in the operation process, so that the insulator is easy to fly off and damage under severe environments such as strong wind, ice coating and the like under the front-back pulling force caused by large-span and the like, and the potential safety hazard of various power systems is easy to be caused. Therefore, a novel insulator fixing device needs to be designed.
The utility model patent of China with the bulletin number of CN216289871U discloses an overhead line column type insulator binding hardware fitting, which comprises a round clamping seat and a wire fixing clamp, wherein the round clamping seat is formed by fixing two semicircular rings at the umbrella skirt at the upper end of a needle type or column type insulator in a closed loop manner by bolts; the fixed wire clamp is arch bridge type, and both ends are arranged on the circular clamping seat by bolts, and the fixed wire clamp is used for fixing overhead conductors, and two fixed wire clamps are arranged and are respectively fixed at both ends of the circular clamping seat.
The applicant has developed the overhead line column insulator binding hardware in the earlier stage, however, in the subsequent use process, the following technical problems exist in the prior art:
the circular clamping seat of the binding hardware fitting is two semicircular rings and is fixed at the umbrella skirt position at the upper end of the needle type or column type insulator by adopting a bolt closed loop. Because the needle type or column type insulator has multiple specifications, the umbrella skirt of the circular clamping seat and the insulator are not completely matched, and part of the insulator exists, and the binding hardware fitting can be fixedly installed, but a certain and larger gap still exists between the semicircular ring and the umbrella skirt surface of the insulator. This causes in the strong wind environment that semicircle ring and insulator can collide constantly because of the swing of cable makes both sides, and semicircle ring adopts the metal material, damages the insulator easily.
