Abstract

The invention discloses solid insulated switchgear. A main incoming line switch is arranged inside a vacuum interrupter; the upper end of the main incoming line switch is movably connected with the lower end of an insulated pulling rod; the upper end of a main switching cable outgoing line cylinder is movably connected with the lower end of the vacuum interrupter; the surface of a transmission rod is provided with outer thread and is located at the lower part of the solid insulated switchgear; the inner surface of an isolated knife is provided with inner thread and sleeves the transmission rod; and the isolated knife is connected with the upper end of the main incoming line switch through a conductive insert. Through arranging the main incoming line switch in the vacuum interrupter, the insulated level is enhanced while the size is reduced, and a solid and air-combined insulated mode is used for narrowing the space occupied by the whole switchgear; and movable connection is adopted among parts, the operation is simple, and convenience is provided for transport, maintenance and mounting of products.

Description

technical field [0001] The invention relates to the technical field of high voltage switches, in particular to a solid insulated switchgear. Background technique [0002] High-voltage switchgear refers to indoor and outdoor AC-DC switchgear operating in a power system with a voltage of 3kV and above and a frequency of 50Hz or below. It is mainly used in power systems (including power plants, substations, transmission and distribution lines, and industrial and mining enterprises, etc.) The control and protection of users) can not only put some power equipment or lines into operation or out of operation according to the needs of power grid operation, but also quickly remove the faulty parts from the power grid when power equipment or lines fail, so as to ensure that there are no faulty parts in the power grid The normal operation of equipment and the safety of operation and maintenance personnel. [0003] At present, the widely used high-voltage switchgear is mainly based on ...
