Embodiment 1

[0040] This embodiment provides a dual power conversion mechanism, such as Figure 1 to Figure 3 shown, which includes:

[0041] A commonly used power switch 1 is a vacuum tube switch, which includes a first moving contact 2 and a first static contact 3 opposite to the first moving contact 2;

[0042] The standby power switch 4 is a vacuum tube switch, which includes a second moving contact 5 and a second static contact 6 opposite to the second moving contact 5; existing power transfer switches all use air arc-extinguishing contacts , referred to as the air contact. It takes at least 10ms to extinguish the arc generated when the moving contact and the static contact are separated under air conditions; Together, a travel time of at least 20ms must be reserved for existing moving contacts. Therefore, the existing dual power supply switch cannot complete the conversion within 20ms. In this application, a vacuum tube switch is used to replace the existing air arc-extinguishing...

Abstract

The invention discloses a dual-power conversion mechanism and a power supply power having the dual-power conversion mechanism. The dual-power conversion mechanism includes a common power switch including a first moving contact and a first static contact opposite to the first moving contact, a standby power switch includes a second moving contact and a second static contact opposite to the second moving contact, and a driving mechanism including a driving member which is connected with the first moving contact and the second moving contact and is driven to reciprocate, wherein the driving member has a power-off position capable of making the common power switch and the standby power switch achieve simultaneous power off, a first power-on position capable of making the common power switch powered on and the standby power switch powered off, and a second power-on position capable of making the standby power switch powered on and the common power switch powered off. The dual-power conversion mechanism is advantaged in that a problem of serious safety risks caused by the lack of a mechanical self-locking device between a common power and a standby power of a dual-power conversion mechanism in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power conversion switches, in particular to a dual power conversion mechanism and a power supply with the dual power conversion mechanism. Background technique [0002] The dual power supply conversion mechanism is the main part of the power supply with dual power supplies. The dual power supply conversion mechanism has two sets of static contacts connected to the normal power supply and the standby power supply respectively, and a set of moving contacts or two sets of moving contacts connected to the above static contacts. together form the output. Relying on the opening / closing actions of the moving contacts and different sets of static contacts, the above output ends are connected to different power supplies. [0003] The dual power conversion mechanism in the prior art lacks a mechanical self-locking device between the normal power supply and the backup power supply, and the control switches of the n...
