Problems solved by technology

[0002] When the existing three-phase power cables are connected to oil transformers, oil switches and other equipment, they generally adopt a split-type multi-component combination method. There are many parts and large volume, and the installation and maintenance are complicated and inconvenient.
Chinese Patent No. 200420020971.4 discloses a "buried transformer high-voltage cable connector". Although it has the advantage of three-phase plugging and unplugging at the same time, the components are small but numerous, and its high-voltage live parts have low compressive strength and require plastic insulation. The bracket is isolated, and the insulation medium needs to be perfused to pass the AC withstand voltage test

Embodiment Construction

[0015] See Figure 1~ image 3 As shown, the main body of the connector: the shape is a segmented cylindrical shape with a flange, and the internal structure is divided into four sections: the first section is at the upper end and is a cylindrical channel 1 with a larger diameter and a shorter length. The second section in the middle is at least three independent cylindrical tunnels 2 with a relatively long length: they are evenly distributed at the lower end of tunnel 1, and the upper end is connected to tunnel 1, while the lower end of tunnel 2 is independent and smaller. The channel 3 is connected. The third section is also in the middle. It is a smaller channel 3 with a relatively short length: its upper ends are independently connected to the channel 2 and there is a socket 4 in the center of the interior. The fourth section is at the lower end, which is the pre-embedded section: in the main body of the connector, a socket 4 corresponding to the channel 3 is pre-embedded, the ...

Abstract

The provided small three-phase cable connector comprises a main body with at least independent three column channels every pre-buried metal plug and a fit bolt as screw form and pawl top opening, wherein the outside wall of connector is flange segmental column-form. This invention has well voltage endurance feature, and fit to wide application.

Description

Technical field: [0001] The invention relates to electrical equipment for power cables, and is a three-phase power cable connector suitable for oil transformers, oil switches and SF6 electrical equipment. Background technique: [0002] When the existing three-phase power cables are connected to oil transformers, oil switches and other equipment, they generally adopt a split multi-component combination method, which has many parts and large volume, and is complicated and inconvenient for installation and maintenance. Chinese Patent No. 200420020971.4 discloses a kind of "underground transformer high-voltage cable connector". Although it has the advantages of three-phase plugging and unplugging, the parts are small but numerous, and its high-voltage live parts have low voltage resistance and require plastic insulation. The stent is isolated, and the insulating medium needs to be poured to pass the AC withstand voltage test. Summary of the invention: [0003] The purpose of the pre...
