Embodiment Construction

[0028] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The following descriptions in the specification are preferred implementation modes for implementing the present invention, but the descriptions are for the purpose of illustrating the general principles of the present invention, and ...

Abstract

An operating mechanism having three operating positions, the mechanism comprising: a front board (1), a rear board (2), an output module (8), an operating shaft module (3), a ground-side on-off switch board module (4), an isolation-side on-off switch board module (5), and a spring module (6). The operating shaft (31) is a core component of the operating shaft module (3). The output module (8) is mounted on the operating shaft (31), and rotatable about an axis of the operating shaft (31). A ground-side on-off switch board (41) is mounted on the operating shaft (31) and near the front board (1). The isolation-side on-off switch board (51) is mounted on the operating shaft (31) and near the rear board (2), and is rotatable about the axis of the operating shaft (31). The operating mechanism having three operating positions provides an output in a simple manner, reduces the volume of the switches, and enables universality of the mechanism.

Description

technical field [0001] The application relates to the technical field of high-voltage switch cabinets, in particular to a three-station operating mechanism. Background technique [0002] The three-position switch is often used in fully enclosed combined electrical appliances or composite electrical appliances, and is not a separate product. Commonly used in ring network cabinets. The so-called three-position refers to three working positions: the closing position where the main breakout of the isolating switch is connected, the isolation position where the main breakout is separated, and the grounding position on the grounding side. The three-position switch actually integrates the functions of the disconnector and the grounding switch. [0003] The three-position switch requires fast and accurate closing and grounding reliability, and the operating mechanism is its core component. At present, the existing three-position switch spring operating mechanism in my country has...
