Abstract
The utility model discloses a combined insulator arrester. The combined insulator arrester comprises an insulating sleeve with skirts, an insulating tube arranged in the insulating sleeve, and an upper fitting and a lower fitting, which are fixedly connected with the upper and lower ends of the insulating sleeve respectively. A tubular cavity with crossed zinc oxide valves is arranged in the insulating tube. A spring is arranged at each of the two ends of the tubular cavity. The upper spring is arranged between the upper end of the tubular cavity and the upper fitting, and the lower spring is arranged between the lower end of the tubular cavity and the lower fitting. A cavity for storing a drying agent is formed in each of the upper and lower fittings, and is separated from the corresponding spring in a sealing way. A bleeder hole is formed in each cavity, and is communicated with the interior of the cavity. A sealing plug is arranged in each bleeder hole. The combined insulator arrester is simple and rational in structure and high in practicability, the tension load bearing capability of the arrester can be effectively improved, and the stability of the arrester is improved.
Description
Technical field
The utility model relates to the composite insulator lightning arrester.
Background technology
