Problems solved by technology

Existing strain insulators mainly rely on the umbrella shed to protect the mandrel. When encountering rain, snow, hail and other weather, the sheath is easily broken by external impact or corroded due to contact with rain and snow, thereby weakening the core. The protective effect of the rod shortens the service life of the tension insulator and also brings safety hazards to power transmission and transformation

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] As shown in the figure, a rainproof tension insulator includes a mandrel 1, the mandrel 1 is arranged horizontally and has several sheds 2 fixedly sheathed on the outer wall, and iron caps 3 are fixedly sheathed at both ends of the mandrel 1 , the solid outer side of the iron cap 3 is connected with a fixer 9, and the joint of the umbrella skirt 2 at both ends is provided with a bearing 5, and the inner wall of the bearing 5 is fixedly connected with the described umbrella skirt 2 on both sides of the joint, The top of the outer wall of the bearing 5 is fixedly connected with a semi-cylindrical rain shield 6 through a support rod, and the bottom of the outer wall of the bearing 5 is fixedly connected with a counterweight device 7 through a support rod, and the mass of the counterweight device 7 is greater than that of the Describe the quality of the ra...

Abstract

The invention discloses a rainproof strain insulator. The rainproof strain insulator comprises a core rod, umbrella skirts, iron caps, reinforced rings, bearings, rain shielding plates, weight balanceapparatuses, bird-expelling needles and fixers; the umbrella skirts are fixedly arranged outside the core rod in a sleeving manner; the iron caps are fixedly arranged at the two ends of the core rodin a sleeving manner; the fixers are fixedly connected with the outer sides of the corresponding iron caps; the bearings are fixedly connected in the umbrella skirt connecting positions at the two ends; the rain shielding plates are fixedly connected with the top of the bearings through supporting rods; and the weight balance apparatuses are fixedly connected with the bottoms of the bearings through the supporting rods. By virtue of additional rain shielding plates outside the umbrella skirts, contact between the umbrella skirts and rain and snow in rainy and snowy days can be avoided, therebyavoiding corrosion to the umbrella skirts by rain and snow, avoiding a phenomena of umbrella skirt breaking caused by external force impact, reinforcing the protection effect on the core rod, prolonging the service life of the strain insulator, and maintaining safety operation of power transmission and transformation.

Description

technical field [0001] The invention relates to the technical field of electric insulation equipment, in particular to a rainproof tension insulator. Background technique [0002] Tensile insulators have been widely used in power transmission and transformation equipment to withstand certain voltage and mechanical stress between conductors of different potentials or between conductors and grounding components. Existing strain insulators mainly rely on the umbrella shed to protect the mandrel. When encountering rain, snow, hail and other weather, the sheath is easily broken by external impact or corroded due to contact with rain and snow, thereby weakening the core. The protective effect of the rod shortens the service life of the tension insulator and also brings safety hazards to power transmission and transformation. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art and provide a rainproof tension insulator. [0004] In or...
