Abstract

The invention, which belongs to the technical field of direct current transmission, relates to an opening structure of a direct-current circuit breaker. The opening structure comprises a first conductive terminal and a second conductive terminal; and a screw rod is arranged between the first conductive terminal and the second conductive terminal, wherein the rotation directions of the two sides ofthe screw rod are opposite. A first opening-closing assembly and a second opening-closing assembly are respectively connected to two sides of the screw rod; the first opening-closing assembly is electrically connected to the first conductive terminal; and the second opening-closing assembly is electrically connected with the second conductive terminal. On the basis of the split structure, quick and effective opening and closing of the mechanical circuit breaker are realized.

Description

technical field [0001] The invention relates to an opening structure of a direct current circuit breaker, which belongs to the technical field of direct current transmission. Background technique [0002] With the depletion of global fossil energy and the increasing environmental problems, the large-scale development and utilization of renewable energy such as wind energy and solar energy has become an important means for countries to adjust their energy structures. As a result, large-scale renewable energy will be integrated into the grid. However, due to the intermittency and randomness of new energy grid integration, it is difficult for the traditional grid structure and electrical equipment to accept large-scale renewable energy, and even "abandoned wind" and "abandoned light". In this context, the multi-terminal DC system based on flexible DC transmission technology has been proposed and recognized as an effective means to solve the above problems. The development of DC...
