Abstract
The utility model relates to a variable diameter tool used for a power-frequency voltage-withstand test device. The power-frequency voltage-withstand test device comprises a test cylinder and an installation assembly arranged in the test cylinder and used for installing a piece to be tested. One end of the installation assembly is electrically connected with a high voltage introducing device, and the other end of the installation assembly is connected with a connection end of the piece to be tested. The variable diameter tool is composed of a variable diameter cylindrical shell and connection flanges arranged at two ends of the variable diameter cylindrical shell. The variable diameter cylindrical shell is a gradually enlarging cylindrical shell or a gradually shrinking cylindrical shell. The variable diameter cylindrical shell has a mother end, the cylinder diameter at the mother end is identical to the cylinder diameter of a connection end of the installation assembly, and the variable diameter tool is connected with the connection end of the installation assembly through the flange at the mother end. The variable diameter tool used for the power-frequency voltage-withstand test device is installed at a high voltage introducing end of the power-frequency voltage-withstand test device. Voltage-withstand tests on insulators of various specifications can be carried out by varying diameters. The variable diameter tool improves the versatility of voltage-withstand test equipment, has a simple structure and is suitable for popularization.
