Abstract: |
Typhoon meteorological disasters occur frequently, which seriously threaten the safe and stable operation of old transmission lines. The old transmission towers can be retrofitted with composite insulated cross arms to solve the problems of low capacity of wind protection design and insufficient distance between conductor and ground. The paper analyzes the wind load and bearing capacity of composite insulated cross-arm towers under the action of a typhoon through theoretical calculation and finite element analysis and puts forward the calculation method of wind load under the action of a typhoon, and it is revealed that typhoon has less influence on the force of composite cross arm and greater influence on the deformation of the composite cross-arm. Finally, the bearing capacity of a composite insulated cross-arm tower under typhoon load is proposed. |
