Auto-synchronous dual-power change-over switch with double-breakpoint moving contact

Abstract

The invention relates to the technical field of uninterruptible power supplies, and discloses an automatic synchronous dual-power change-over switch with a double-breakpoint moving contact. The change-over switch comprises a shell, the left side of the inner wall of the shell is fixedly connected with an input end, the right side of the inner wall of the shell is fixedly connected with an output end, and the outer side of a rotating wheel is movably connected with a stop lever. A pressing ball is fixedly connected to the interior of the rotating wheel, an air bag is fixedly connected to the interior of the driving wheel, and a driving block is slidably connected to the outer side of the driving wheel. According to the automatic synchronous dual-power change-over switch with the double-breakpoint moving contact, the left feeler lever and the right feeler lever are driven to rotate through the rotary switch, the left feeler lever and the right feeler lever drive the air pipe to slide, and the air pipe drives the piston to slide; when the piston slides to the input end and the output end, the piston enables air in the air pipe to enter the top ball, and the top ball expands to drive the sliding rod to slide; through cooperative use of the sliding rod and the stop lever, the effect that the contacts at the two ends can move synchronously is achieved.

Description

technical field [0001] The invention relates to the technical field of uninterruptible power supplies, in particular to an automatic synchronous dual power supply transfer switch with double breakpoint moving contacts. Background technique [0002] The uninterruptible power supply is a system device that connects the battery with the main engine, and converts direct current into mains power through a module circuit such as the main engine inverter. It is mainly used for powering a single computer, computer network system or other power electronic equipment such as solenoid valves, Pressure transmitters, etc. provide stable and uninterrupted power supply, among which dual power transfer switches are widely used in power supply and distribution systems. [0003] In the actual use of the existing dual power switch with double breakpoint moving contacts, it is difficult to ensure that the contacts on both sides move synchronously, which is easy to cause damage to the contacts, a...
