Abstract

A high voltage cable rubber part joint test connecting pipe comprises a pipe body, the pipe diameter of the pipe body is slightly greater than the external diameter of a cable conductor, and 8-12 screw holes penetrating an inner wall are arranged on the pipe wall of the pipe body. Fastening screws are screwed in the screw holes, and the tail ends of the screws are in contact and pressure welding with the cable conductor. The high voltage cable rubber part joint test connecting pipe saves the cost of shielding tiles, is simple and convenient to install, eliminates the other problems caused by the joint close or sharp corner scratch of the shielding tiles, and saves the production, transportation and installation cost substantially.

Description

高压电缆橡胶件接头试验用连管Connecting pipe for rubber joint test of high voltage cable

技术领域 technical field

本发明涉及电缆附件，尤其涉及不限电缆平方规格的各类110kV及以上电缆橡胶件接头安装附件。 The invention relates to cable accessories, in particular to installation accessories for various 110kV and above cable rubber joints with unlimited cable square specifications.

背景技术 Background technique

现有各电缆附件公司使用的接头试验连管，大多是并不专用或者说是并不专业，主要表现在不但无法满足240～2500mm2接头的通用试验，而且大方采用压接的方式，而且只能一次性使用，造成严重浪费。所以这些方式，不但存在明显的缺陷，而且需要很多规格，一次性使用成了极大的浪费。 Most of the joint test tubes used by cable accessories companies are not dedicated or not professional. The main performance is that not only cannot meet the general test of 240-2500mm2 joints, but also generously adopt the crimping method, and can only Disposable use, causing serious waste. Therefore, these methods not only have obvious defects, but also require many specifications, and one-time use has become a great waste.

发明内容 Contents of the invention

本发明针对现有技术的不足，提供了一种可重复使用，无需压接，无需屏蔽瓦，节约了安装时间，大大提高工作效率的高压电缆橡胶件接头试验用连管。 Aiming at the deficiencies of the prior art, the present invention provides a high-voltage cable rubber joint test connecting pipe that can be used repeatedly without crimping or shielding tiles, saves installation time, and greatly improves work efficiency.

为实现本发明目的，提供了以下技术方案：高压电缆橡胶件接头试验用连管，包括管体，管体管径略大于电缆导体外径，其特征在于管体管壁上开设有8~12个贯通内壁的螺孔，螺孔内旋接有紧定螺钉，螺钉末端与电缆导体接触压接。 In order to realize the purpose of the present invention, the following technical solutions are provided: the connecting pipe for the test of the rubber part joint of the high-voltage cable includes a pipe body, and the diameter of the pipe body is slightly larger than the outer diameter of the cable conductor, and it is characterized in that 8 to 12 A screw hole penetrating the inner wall, a set screw is screwed in the screw hole, and the end of the screw is in contact with the cable conductor for crimping.

作为优选，螺钉末端为圆锥形，圆锥形底端为圆弧状凸体。 Preferably, the end of the screw is conical, and the bottom end of the conical shape is an arc-shaped convex body.

作为优选，管体外壁光洁度。 As a preference, the smoothness of the outer wall of the tube.

作为优选，螺钉设置为上下对称。 Preferably, the screws are arranged symmetrically up and down.

本发明有益效果：本发明节约了屏蔽瓦的成本，安装简便，更排除了因屏蔽瓦的合缝或尖角产生的刮伤等引出的其它问题，大大节约了生产、运输、安装成本。 Beneficial effects of the invention: the invention saves the cost of shielding tiles, is easy to install, and eliminates other problems caused by joints or sharp corners of shielding tiles, greatly saving production, transportation and installation costs.
