Abstract
The utility model relates to a kind of ac panel power switch devices, including main power source contact, backup power source contact, armature contact, electric pushrod, main power source contact and backup power source contact are fixedly mounted on inside device, armature contact is mounted on swing rod, swing rod is hinged with device, the movable end of electric pushrod and swing rod are hinged, and electric pushrod connects trigger, and trigger is separately connected main power source contact, backup power source contact and armature contact.The beneficial effects of the utility model are: when the power break occurs, backup power source can be switched fast, lost caused by reducing because of power-off.
Description
Technical field
The utility model relates to ac panel more particularly to a kind of ac panel power switch devices.
Background technique
AC distribution panel and is supervised to power supply system for connecting power supply, transformer, converter and other loads
It controls and protects, have and carry out on-off, conversion between power supply and various loads, the control such as defined method of operation of realization
The equipment of function.When main power source breaks down, ac panel needs to be connected to backup power source.But it generallys use in the prior art
Manual switching extends power-off time.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of ac panel
The speed of cut-in stand-by power supply can be improved in power switch device.
The utility model is to be achieved by the following technical programs:
A kind of ac panel power switch device, including main power source contact, backup power source contact, armature contact, electric pushrod,
Main power source contact and backup power source contact are fixedly mounted on inside device, and armature contact is mounted on swing rod, and swing rod and device are cut with scissors
It connects, the movable end and swing rod of electric pushrod are hinged, and electric pushrod connects trigger, and trigger is separately connected main power source contact, standby
With power contact and armature contact.
According to the above technical scheme, it is preferable that armature contact connection auxiliary switch.
The beneficial effects of the utility model are: when the power break occurs, backup power source can be switched fast, reduce because power-off is made
At loss.
Detailed description of the invention
Fig. 1 shows the schematic view of the front view of the embodiments of the present invention.
In figure: 1. main power source contacts, 2. backup power source contacts, 3. armature contacts, 4. electric pushrods, 5. swing rods, 6. triggerings
Device, 7. auxiliary switch.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, a kind of ac panel power switch device of the utility model, including main power source contact 1, backup power source touching
Point 2, armature contact 3, electric pushrod 4, main power source contact and backup power source contact are fixedly mounted on inside device, armature contact peace
On swing rod 5, swing rod is hinged with device, and the movable end and swing rod of electric pushrod are hinged, and electric pushrod connects trigger 6, touching
Hair device is separately connected main power source contact, backup power source contact and armature contact.
In the present embodiment, armature contact is connected to main power source contact, when main power source breaks down, trigger by swing rod
Start electric pushrod, electric pushrod drives swing rod movement, makes armature contact connection backup power source.
According to the above technical scheme, it is preferable that armature contact connection auxiliary switch 7.Auxiliary switch can control the connection of circuit
Or it disconnects.
The beneficial effects of the utility model are: when the power break occurs, backup power source can be switched fast, reduce because power-off is made
At loss.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
