Detailed Description
As shown in fig. 1, a three-phase common-box bus with temperature compensation is characterized in that a temperature compensation expansion joint 3 is connected between two adjacent shells 1 through a flange structure; the inner cavities of the two shells 1 are respectively provided with insulators 7, and the three-phase conductors 4 are connected between the two insulators 7; one of the insulators 7 is provided with a plug contact 6, the end part of the three-phase conductor 4 at the corresponding position is also provided with the plug contact 6, and the adjusting conductor 5 is inserted between every two plug contacts 6 at the corresponding positions in a sliding manner.
And one end of the three-phase conductor 4, which is far away from the adjusting conductor 5, is connected to the shell 1, and the outer end part of the three-phase conductor is spliced with the insulator 7 at the corresponding position. The stability of the three-phase conductor in the shell is further ensured.
As shown in fig. 2 and fig. 3, the temperature compensation expansion joint 3 has an annular structure, two ends of the temperature compensation expansion joint are tubular structures, the middle of the temperature compensation expansion joint has a bellows structure, and two ends of the tubular structures have flanges. The length of the temperature compensation expansion joint 3 can be adjusted in an expansion mode through the corrugated pipe structure.
To sum up, the three-phase of taking temperature compensation of this application is total to case generating line has solved the three-phase that uses at present and has total case generating line flexible volume less, and the casing is easy to split shortcoming under the special conditions such as the temperature is lower, the difference in temperature is great, whole main bus is longer to can be used to the reliable butt joint of engineering extension port department, be adapted to in the gas-insulated metal enclosed switchgear of 363 kV voltage level. The large expansion amount of the temperature compensation expansion joint compensates the displacement caused by expansion with heat and contraction with cold of the main bus shell in the area with low temperature and large temperature difference, and also compensates the accumulated displacement caused by the large expansion amount of the whole main bus, so that the expansion joint can be used for reliable butt joint of an expansion port in long-term engineering.
