Abstract
The utility model discloses an adjustable insulator arrester. The adjustable insulator arrester comprises an arrester body. The arrester body includes an insulating ceramic sleeve, and a zinc oxide valve sheet and an insulating layer which are disposed in the insulating ceramic sleeve. The arrester body is equipped with an adjustable separating device including adjusting supports, an upper separating terminal, and a lower separating terminal. Each adjusting support comprises a hollow sleeve, and an upper fulcrum bar and a lower fulcrum bar which are disposed in the hollow of the sleeve. A spring and clamping blocks used for clamping are disposed in the hollow sleeve. The upper fulcrum bar and the lower fulcrum bar are abutted against the top of the spring and the bottom of the spring, respectively. The upper separating terminal is disposed on the upper fulcrum bar, while the lower separating terminal is disposed on the lower fulcrum bar and is electrically connected with the zinc oxide valve sheet. The upper fulcrum bar and the lower fulcrum bar are fixed in the sleeve by the clamping of the clamping blocks. The adjustable insulator arrester has a simple structure and is equipped with adjustable separating device which can be timely adjusted according to requirements. Therefore, using security is effectively increased and lightning-protection effect of the arrester is not affected. The adjustable insulator arrester has good practicality.
Description
Technical field
The utility model belongs to the lightning arrester field, is specifically related to a kind of adjustable insulator lightning arrester.
