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 ~ Figure 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, which is a cylindrical hole 1 with a larger diameter and a shorter length. The second section is in the middle, which is at least three independent cylindrical channels 2, and the length is relatively long: they are evenly distributed at the lower end of the channel 1, and the upper ends are all connected with the channel 1, and the lower ends of the channel 2 are respectively independently connected to the smaller ones. Channel 3 is connected. The third section is also in the middle, which is a smaller channel 3 with a shorter length: its upper end is independently connected to the channel 2, and the inner center has a socket 4. The fourth section is at the lower end, which is the embedded section: in the main body of the connector, a socket 4 corres...

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 of 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-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. Invention content: [0003] The...
