Double-power-supply automatic change-over switch structure with neutral line overlapping function

Abstract

The invention discloses a double-power-supply automatic change-over switch structure with a neutral line overlapping function. A switch body comprises a common power supply three-phase line assembly, a common power supply neutral line assembly, a standby power supply three-phase line assembly and a standby power supply neutral line assembly, which are parallel to one another and are symmetrically arranged on a base, and further comprises a driving mechanism, wherein the driving mechanism comprises a common power supply driving rotary shaft and a standby power supply driving rotary shaft; the common power supply neutral line assembly is driven by the standby power supply driving rotary shaft; and the standby power supply three-phase line assembly is driven by the common power supply driving rotary shaft. With the adoption of the double-power-supply automatic change-over switch structure with the neutral line overlapping function, disclosed by the invention, a parallel connecting rod mechanism and a connecting rod mechanism are utilized, so that a rapid, accurate and reliable automatic change-over function can be provided. The double-power-supply automatic change-over switch structure has the advantages of simple structure, guarantees of neutral line overlapping time, high reliability, long service life, high stability, easiness of machining and assembling parts and low cost, and is suitable for large-batch production.

Description

technical field [0001] The invention relates to the technical field of a four-pole dual-power automatic transfer switch with a neutral line (N pole) in an automatic transfer switch, in particular to a dual-power automatic transfer switch structure with a neutral line overlapping function. Background technique [0002] The automatic transfer switch appliance is a widely used terminal appliance. It mainly uses the controller on it to drive the electric operating mechanism to control the action of the executive switch, so as to connect or break the common and standby power supply, so as to ensure the safety and production of the power system. continuity. At present, the commonly used four-pole dual-power automatic transfer switch with neutral line (N pole) is mainly divided into synchronous conversion between neutral line (N pole) and phase line poles and overlapping conversion between neutral line (N pole) and phase line poles. Two categories. The existing automatic transfer...
