Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0012] like figure 1 As shown: the present invention includes a strain insulator string 1, a cross-arm composite insulator 2, a lightning arrester 3, a wire fixing clamp 4, a line tower 5, a cable terminal joint 6, a grounding box 7, a protective cover 8, a lightning arrester discharge counter 9, Mounting plate 10 , cable terminal pole tower 11 and terminal grounding pole 12 .

[0013] Reliable operation of cable terminals must consider external insulation requirements, lightning protection requirements, mechanical performance requirements, and convenient repair and maintenance requirements. The main basis for external insulation performance is whether the arrangement meets corona discharge under dry and humid conditions; The main basis for the requirement is whether the arrester can effectively protect the cable terminal; the basis for the mechanical performa...

Abstract

The invention relates to a tower arrangement structure, and in particular relates to a tower arrangement structure at a cable terminal. The tower arrangement structure is used for improving the safety of the cable terminal, belonging to the technical field of electrical safety. The structure comprises a line tower and a cable terminal tower at one side of the line tower, wherein the cable terminal tower is provided with a mounting plate which is fixedly provided with an arrester and a cable terminal joint; the distance L between the cable terminal joint and the arrester is 1-1.5m, thus reducing the field intensity distribution on the cable terminal joint and decreasing the occupied land resources. The structure is good in effect and stable in operation, and is safe and reliable.

Description

technical field [0001] The invention relates to a pole tower layout structure, in particular to a pole tower layout structure for a cable terminal, specifically a pole tower layout structure for improving the safety of a cable terminal, and belongs to the technical field of electric power safety. Background technique [0002] In recent years, the application of high-voltage cables of 110kV and above has risen sharply, and the number of cable accidents has also increased year by year. Many high-voltage cable accidents have occurred in many areas. The requirements for strengthening quality control and reducing cable failure rates are imminent. [0003] At present, the design of cable lines mainly includes single loop, double loop, double split and double split double loop and other methods. The design methods of cable terminal layout in various ways are various. The spatial arrangement of various components such as lightning arresters and down-conductor connections has mutual ...
