Electric conversion operating mechanism available for three power sources

Abstract

The invention discloses a power-driven conversion operation mechanism available for three power supplies. The power-driven conversion operation mechanism comprises a left side plate, a right side plate, three fixed plates, a first working plate, a second working plate and a third working plate, wherein the three fixed plates are arranged between the left side plate and the right side plate and are in parallel to one another, the first working plate, the second working plate and the third working plate are sequentially arranged above each fixed plate from bottom to top and are parallel to the fixed plates, one side of the right side plate is provided with a rotation assembly, a driving assembly is arranged on each of the first working plate, the second working plate and the third working plate, and the driving assemblies on the first working plate, the second working plate and the third working plate are respectively engaged with the rotation assembly and act under the driving of the rotation assembly. The power-driven conversion operation mechanism has the advantages of simple structure and convenience in driving.

Description

technical field [0001] The invention relates to a switching mechanism for automatically switching from a common power supply to a standby or emergency power supply in a power distribution system where there are two backup power supplies for power supply, in particular to an electric switching operation mechanism that can be used for three power supplies. Background technique [0002] At present, the dual power automatic transfer switch has become mature day by day as an integral part of the distributed control system of electric power supply. However, as people have higher and higher requirements for power usage in daily production and life, new requirements are put forward for the security inspection and stability of the power supply system. Especially in some special occasions and requirements, dual power supply has obviously not met its requirements. Require. [0003] In the three-power supply system, the access method for the three-way input power supply can only be one...

However, as people have higher and higher requirements for power usage in daily production and life, new requirements are put forward for the security inspection and stability of the power supply system. Especially in some special occasions and requirements, dual power supply has obviously not met its requirements. Require

[0003] In the three-power supply system, the access method for the three-way input power supply can only be one power supply at a time, and two or more power supplies cannot be connected at the same time, otherwise it will lead to danger or accidents

However, in the national standard "Code for Design of Power Supply and Distribution System" (GB50052-2009), the regulations for occasions requiring the use of three power sources are relatively special or rare, so that the automatic conversion of common power sources that can be selected in the power supply system of three power sources Few switching mechanisms to backup or emergency power
