Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] A specific embodiment of the valve tower structure of a high-voltage DC circuit breaker of the present invention, as Figure 1 to Figure 5 As shown, the valve tower structure in this embodiment includes a plurality of circuit breaker power assemblies 5 for sequential series connection, the plurality of circuit breaker power assemblies 5 are arranged in layers at intervals along the upper and lower directions, and any adjacent two-layer circuit breaker power assemblies The interlayer support structure is fixedly installed between them to form the valve tower main body 300. The interlayer support structure here specifically adopts the interlayer support insulator 81, and each valve tower main body has 5 layers of circuit breaker power components 5 respectively. In this embodiment, the valve tower bodies 300 here are arranged in two rows at intervals...

Abstract

The invention relates to a high voltage DC breaker valve tower structure. The high voltage DC breaker valve tower structure comprises multiple breaker power assemblies which are sequentially connected in series and are distributed from up to down with intervals layer by layer, an inter-layer supporting structure is arranged between any two adjacent breaker power assemblies to form a valve tower body, the valve tower body is supported on a bottom portion supporting insulator structure, the valve tower structure further comprises a lightning arrester assembly correspondingly arranged at a side of the valve tower body, and the valve tower structure further comprises a suspension device used for suspending the valve tower body under a corresponding suspension beam. The multiple breaker power assemblies are distributed from up to down with intervals layer by layer and are relatively tight in space, so the horizontal land occupation area is relatively small, moreover, the valve tower body employs a dual-reinforcement measure capable of realizing both the top portion suspension effect and the bottom portion supporting effect, the valve tower antivibration performance can be effectively improved, structural strength requirements for the bottom portion supporting insulator structure are reduced, and more breaker power assemblies can be laminated in the vertical direction.

Description

technical field [0001] The invention relates to a valve tower structure of a high-voltage direct current circuit breaker. Background technique [0002] The multi-terminal DC transmission and DC grid technology based on flexible DC is one of the effective technical means to solve the problem of new energy grid connection and consumption, and the high-voltage circuit breaker is the key equipment for building a DC grid, which is safe and reliable for the DC transmission system and DC grid. Operation plays an extremely important role. For a long time, under the condition of high voltage and high current, how to solve the problem that the DC current has no natural zero-crossing point and it is difficult to break, and the rapid rise of the DC short-circuit current requires it to be broken within a few milliseconds, which has plagued academic circles and engineering at home and abroad. Therefore, it is known as a century-old problem in the field of electric power technology. [0...
