Abstract

The invention discloses a split type high-voltage series compensation damping MOV. The split type high-voltage series compensation damping MOV comprises resistance slice devices and a flow-equalizing connection plate; one ends of the resistance slice devices are fixedly connected with an electric reactor; the other ends of the resistance slice devices are fixedly connected with the flow-equalizing connection plate; the flow-equalizing connection plate comprises a circular plate and installation arms; the circular plate and the installation arms are integrally cut and formed; an opening is formed on the circular plate; and each installation arm is connected to the resistance slice device, wherein two installation arms are connected to multiple resistance slice devices. By adoption of the split type high-voltage series compensation damping MOV disclosed by the invention, the split structure in electric reactor parallel linear resistance and damping MOV can be realized; simultaneously, the flow-equalizing problem of resistance slices can be solved well; the resistance slices are good in electrical contact, compact in structure, free from air cavity and good in sealing performance, and can release stress well when being heated; and the through-current capability of the resistance slices is improved.

Description

technical field [0001] The invention belongs to the technical field of lightning arresters for power systems, and in particular relates to a split-type high-voltage series compensation damping MOV. Background technique [0002] With the rapid development of my country's electric power industry, my country's power grid has entered a new stage of large power grids, large units, and high-voltage direct current transmission. The application of long-distance and large-capacity high-voltage transmission technology has become an urgent need for the development of my country's electric power industry. Power transmission makes the stability of the system more and more prominent in our country. The series compensation technology that can improve the power system transmission capacity and improve the stability of the power system is bound to be widely used in the high voltage field. The metal oxide voltage limiter (MOV) is an important protection device in the series compensation devic...
