Description

[technical field] [0001] The invention relates to a device for direct current transmission, in particular to a thyristor press-fitting mechanism for a direct current transmission converter valve. [Background technique] [0002] With the development of power electronics technology, thyristor-based converter valves are more and more widely used in power systems. With the continuous improvement of thyristor parameters, the requirements for press-fitting are becoming more and more stringent, especially for large-size flat thyristors and high-voltage thyristor valves, the mechanical strength and electrical insulation strength of the thyristor press-fitting mechanism are required to be high, and the compact structure Safe and reliable, stable performance, and easy to install. [0003] Existing thyristor press-fitting mechanisms are of various types, basically adopting the method of applying pressure through the center line of the thyristor and radiator, and there are also various...
