Problems solved by technology

[0003] This kind of dual power supply switch can realize the conversion of dual power supply, but there is a certain power interruption time during the conversion, and because the mechanical switching system of this kind of dual power supply switch adopts a linkage system, when the main power supply circuit is cut off, the backup power supply can connected, so its power interruption time is strictly limited by its mechanical switching system, resulting in a longer interruption time
For some power-consuming units, such as the textile industry, such a long interruption time will cause the entire production line to take several hours to reorganize before continuing to run. This kind of refurbishment is a huge loss for the enterprise.

Abstract

The invention discloses an uninterrupted dual power supply changeover switch, which comprises an encloser, a contact on-off system and a mechanical transmission system. The invention is structurally characterized in that the uninterrupted dual power supply changeover switch comprises two mechanical transmission systems which are independent of each other and two contact on-off systems which are independent of each other; each of the mechanical transmission systems drives one contact on-off system matched with the mechanical transmission system. The invention has the advantages of compact structure and small volume. In addition, the invention can eliminate power interruption, thus achieving uninterrupted conversion of dual power supply.

Description

technical field [0001] The invention belongs to the technical field of power switches, and in particular relates to an uninterrupted dual power switch. Background technique [0002] Chinese patent 200420022005.6 discloses a dual power supply phase loss automatic detection transfer switch, which consists of a transfer switch and an automatic control. The transfer switch includes a linkage contact opening and closing system and a mechanical switching system; the automatic control part includes Item detection system, electromagnetic control system; transfer switch and automatic control are connected through the transmission mechanism to form a whole. [0003] This kind of dual power supply switch can realize the conversion of dual power supply, but there is a certain power interruption time during the conversion, and because the mechanical switching system of this kind of dual power supply switch adopts a linkage system, when the main power supply circuit is cut off, the backup...
