Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As Figure 1-3, the major loop operating mechanism of the present invention can independent withdraw-type dual-power transfer switch, including, two
The end of incoming cables 1 that group connects with two set power supplys respectively；Two groups of leading-out terminals connected with electrical equipment respectively 2,
Two set operating mechanisms, often set operating mechanism includes operating unit 3 respectively, as executor or chopper, Yi Jifen
She Zhi not fix the moving contact 4 being connected with the input terminal of operating unit and outlet terminal, operating unit 3 is containing in order to control electricity
Road connection or the main contact 6 disconnected；Described moving contact mates setting, i.e. described inlet wire with corresponding end of incoming cables and leading-out terminal
End and leading-out terminal are the static contact mated with described moving contact, and both connections can use duckbilled union joint, Flos Mume union joint
Etc. various ways；
Propulsive mechanism 5, enters with described in order to carry the operating unit described in two set operating mechanisms and driving and moving contact
Line end and leading-out terminal are switched on or switched off.
Operating unit is utilized propulsive mechanism to support by the present invention breakthroughly, utilizes the space of operating unit to move reality simultaneously
Existing executor is in link position or separate and does not puts, and when being in link position, operating unit can realize the disconnection of power supply and connect
Logical, the operating unit being in separation point position is then in the state of completely disengaging from, so when operating mechanism breaks down, and can be by it
Removal, can realize maintenance under line and not affect the normal work of another operating mechanism, it is achieved that the constantly electricity work of electrical equipment.
Specifically, moving for realizing the space of operating mechanism, described propulsive mechanism is two independent controls or connection
Moving the horizontally moveable of control or the mechanism vertically moved, described operating unit is arranged on described bogey.Use
Bogey cooperative mechanical locking mechanism etc. that is horizontally moveable or that vertically move, can realize the translation of operating mechanism or vertically move
Dynamic, the switching of power supply is effectively ensured.Described operating unit can be controlled main contact to realize two power supplys by electric operating etc.
Automatically switching operation.
Preferably, saving for realizing space, reduce space hold, described propulsive mechanism is two independent controls or linkage
The microscope carrier of the lifting driven controlled, described operating unit is fixedly installed on described microscope carrier.Elevating mechanism is utilized to realize
Lifting type space is moved, and the switching that can realize power supply equally is even automatically switched.Preferably, for ease of the pull-out of operating mechanism,
Being additionally provided with bogey on described microscope carrier, described operating unit is fixedly installed on described bogey.So
Easily operating unit can be pulled out the cabinet of permutator, it is provided that bigger service clearance, maintenance can be realized installing state,
And also allow for entirety and hang load.
The control method of the dual-power transfer switch of the present invention comprises the following steps,
1) moving contact that two operating units are corresponding respectively is in link position with corresponding static contact by propulsive mechanism, holds
Row mechanism drives the main contact of one of them operating unit to close, it is achieved the connection of power supply, and keeps another one operating unit
Main contact disconnect；
2), when needing Switching power, actuator drives operating unit to make the main contact disconnection of original on-position, same
Step or the asynchronous open position main contact that another was originally in are connected；
3) have to time, propulsive mechanism will need to safeguard and be in the operating mechanism of off-state and end of incoming cables and leading-out terminal
Disconnect.
Wherein, the most then according to actual requirement, utilize existing mechanical mechanism all can realize it and control, synchronize control
