Embodiment Construction

[0017] figure 1 It is an embodiment of the present invention—the insulating protective sleeve, which is used to be installed on the incoming line end of the switch, including the housing 1 and the sleeve channel 2, which are formed into an integral structure by one-time molding of silicon rubber material, and the sleeve channel 2 is divided into branch channels 4 It coincides with the axis line of the main channel 5, the main channel and the branch channel. The main channel is a hollow cylinder, and the branch channel is a hollow conical table with a certain taper. The taper matches the taper of the switch bushing. The main channel and the branch channel pass through The necking portion 3 communicates, and the necking portion matches the outer diameter of the switch bushing. When in use, the insulating protective sleeve can be installed vertically on the switch bushing.

Abstract

The invention provides an insulating protective jacket, which can be used at electric joints of distribution equipment such as a cable branching box, a switch cabinet, a ring-network cabinet and the like. The insulating protective jacket is characterized in that the insulating protective jacket comprises a housing and an enclosing passage adapted to a member wrapping an electric joint inside the housing; and the housing adopts integrated structure made of an insulating material.

Description

technical field [0001] The invention relates to an insulating protective fitting in a power network equipment, especially an insulating protective cover, which can be used in the electrical connections of power transmission and distribution equipment such as cable branch boxes, switch cabinets, and ring network cabinets. Background technique [0002] In the transformation of the urban power grid, a large number of power transmission and distribution equipment such as cable branch boxes, switch cabinets, and ring network cabinets need to be used. Therefore, the requirements for the operation safety and reliability of these equipment are getting higher and higher. If the original cable branch box, switch cabinet, the inlet and outlet ports of the ring network cabinet, and the electrical connection with the busbar are directly exposed to the air, dust is easy to accumulate. In a humid environment, such as in some places in southern my country Areas are prone to condensation, and...
