Overview
This outdoor high-voltage disconnector is a high-voltage switchgear with unipolar structure, which can be used for opening and closing circuits when there is voltage and no load in the outdoor 3.6-40.5KV kV line network. It is equipped with fixed hook and self-locking device, which is flexible and reliable, and is operated by insulating hook. The anti pollution outdoor high-voltage disconnector can meet the requirements of users in seriously polluted areas, and can effectively solve the pollution flashover problem of disconnectors in operation.
Features
This outdoor high-voltage disconnector is of single-phase structure, and each phase is composed of chassis, pillar insulator, knife switch, contact, etc. There are screws for adjusting contact pressure and springs for pressing on the side of the knife switch, and a self-locking device for fixing the buckle and connecting it is installed on the upper end for opening and closing the insulating hook bar. The utility model has the advantages of large contact area, low contact resistance, good conductivity and high mechanical strength.
