Problems solved by technology
[0004] In order to solve the above technical problems, the present invention provides an uninterrupted power conversion device for use in power distribution cabinets, to solve the problem that the existing transfer switch needs to be cut off first and then connected to the switch that needs to be switched. There will be a short-term disconnection in the middle circuit, which is not allowed in continuous operation equipment. At the same time, a short-term disconnection is likely to cause impact on circuit components and even damage components.

The invention belongs to the technical field of electric power engineering, particularly relates to an uninterrupted power conversion device for a power distribution cabinet which aims to solve the problems that the circuit components are easily impacted and even damaged due to the fact that an existing change-over switch circuit is in open circuit transitorily. The device comprises an outer shell, the middle part of the outer shell is axially connected with a group of rotating shafts, the group of rotating shaft is connected with a group of rotating contact discs in a sliding manner, and theright side of the interior of the outer shell is fixedly connected with three groups of upper fixed contact pieces. The device is compact and small in structure, can realize the power conversion underthe condition of uninterrupted power supply, improves the operation accuracy, has an automatic disconnection function, and can realize the automatic disconnection when the circuit is in emergency, can protect the circuit, and improves the safety.
Description
technical field [0001] The invention belongs to the technical field of electric power engineering, and more specifically relates to an uninterrupted power conversion device used in a power distribution cabinet. Background technique [0002] In the design of the power distribution cabinet, it is often necessary to switch the power, and the power switch is generally used to switch the power. [0003] For example, application number: CN201010175467.1 Integral power conversion switch, in which the detachable part is integrally formed to reduce errors caused by accumulated assembly tolerances, simplify the manufacturing process, and improve operator convenience. The integrated power transfer switch includes: common power terminals or emergency power terminals respectively formed on the upper part of both sides of the integrated power transfer switch; a module including load terminals, and the load terminals are formed on the lower part of one side of the module to communicate wit...
