Title: UMBRELLA SLEEVE AND ELECTRICAL APPARATUS USING SAME
Abstract:
Disclosed are an umbrella sleeve and an electrical apparatus using same. The umbrella sleeve (100) is arranged on the electrical apparatus, and the electrical apparatus comprises at least two parallel insulators (300); and at least two mounting holes (103) capable of enabling the at least two insulators to pass through and openings (104) corresponding to the mounting holes are arranged on the umbrella sleeve, and the openings are in communication with the mounting holes and the edge of the umbrella sleeve. The electrical apparatus can also comprise a housing (200), and the at least two insulators are connected to the housing by housing connection parts (400); and the umbrella sleeve covers at least the housing connection parts. The umbrella sleeve has a significant effect of increasing creepage distance, and can effectively prevent rain, snow and dirt, and has a better anti-pollution flashover effect; the umbrella sleeve can also effectively prevent rain, snow and dirt from entering the junction regions between the connection parts and the insulators and the housing, and thereby can improve the safety of the electrical apparatus; and the diameter of the umbrella sleeve is larger, and can break a conductive passage forming a rain curtain, at least to some extent avoiding or even eliminating a rain flash accident.
