Valve tower of DC circuit breaker

Abstract

A valve tower of a DC circuit breaker comprises a rapid mechanical switch tower, a power electronic switch tower, an energy consumption lightning arrester tower, a coupling negative pressure driving device, an insulation supporting platform and an isolation transformer. The insulation supporting platform is arranged at the bottom of the valve tower, a transition layer is arranged at the top of theinsulation supporting platform, the rapid mechanical switch tower, the power electronic switch tower, the energy consumption lightning arrester tower and the coupling negative pressure driving deviceare all installed on the transition layer, and the coupling negative pressure driving device is located in the power electronic switch tower; the rapid mechanical switch tower, the power electronic switch tower and the energy consumption lightning arrester tower are arranged on the transition layer. The power electronic switch tower is located on the side face of the rapid mechanical switch tower, and the energy consumption lightning arrester tower is located in front of the rapid mechanical switch tower. The isolation transformer is arranged on one side of the insulation supporting platformand used for providing electric power for the valve tower. The structure is beneficial to independence among the towers, and the problems of complex structural design, complex electrical connection, complex wiring and the like caused by structural staggering are avoided.

Description

technical field [0001] The invention belongs to the field of electric equipment and relates to a valve tower of a DC circuit breaker. Background technique [0002] The overall structure of the DC circuit breaker valve tower includes: fast mechanical switch tower, power electronic switch tower, energy consumption arrester tower, coupling negative pressure drive device installed on the transition layer, insulating support platform and isolation transformer. There are many components in the overall structure and the structure is complex. Affected by the two factors of installation space limitation and complicated electrical connection, the conventional layout method not only takes up a huge space, but also makes the electrical connection very cumbersome, and is not conducive to the layout of power supply cables. and lay out communication fibers. Contents of the invention [0003] In order to facilitate on-site installation and construction, the present invention proposes a c...
