Description
Technical field
The utility model is related to dual power supply technical field more particularly to a kind of double power-supply automatic transferring devices.
Background technology
Existing equipment usually needs to connect dual power supply on using.The double power-supply automatic transferring device occurred on the market at present
(double power supply automatic switching switch) slowly generally at 3 seconds or so, the various electric appliances of transfer process and equipment can all stop switch speed mostly
Machine or needs are restarted, meanwhile, structure is more complicated, expensive, and the general the degree of automation of easy converter is not high, is applicable in
Limitation, sound is also big when dual power supply works, and can only realize power-off switching, and it is big to switch sound, it is impossible to which reflection currently makes very well
Use power conditions.For this purpose, we relate to a kind of double power-supply automatic transferring device
Utility model content
To solve deficiency of the prior art, the purpose of this utility model is to provide a kind of double power-supply automatic transferring device, purport
Not high in the existing simple double power-supply automatic transferring device the degree of automation of solution, the unhappy of conversion speed is applicable in limitation, no indicated work
Can, operating noise can be led to the problem of.
To achieve the above object, the technical solution of the utility model is：A kind of double power-supply automatic transferring device, including 220V
The common power supply of AC, the stand-by power supply of 220V AC, the electromagnetic relay being electrically connected with common power supply, the electromagnetic relay it is normal
Contact portion is opened often with power supply, the normally-closed contact connection stand-by power supply of electromagnetic relay, the movable contact company of the electromagnetic relay
Electrical equipment is connect, the electromagnetic relay uses three normally opened contacts, three normally-closed contact, and the electromagnetic relay is wherein normally opened all the way
Contact connect common power supply indicator and stand-by power supply indicator light with normally-closed contact respectively；The electromagnetic relay coil uses
12V DC power, and transformer and rectifier are connected between the coil terminals of electromagnetic relay and common power supply, the electromagnetism
Voltage detection module is also associated between the coil terminals of relay and common power supply.
The beneficial effects of the utility model：It can automatically switch when common power cut-off or low pressure, use scope is wide, switching speed
Fast switching intervals to be spent in 5-15mS, can realize that various electric appliance instruments, instrument, equipment etc. are not shut down, operating noise is minimum,
Have instruction function, show currently used power status.Meanwhile realize that the common supply voltage of automatic detection is too high or too low automatic
Stand-by power supply is switched to, with the various electric appliance load of protection power source output terminal
Description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of double power-supply automatic transferring device, the standby electricity of common power supply 1,220V AC including 220V AC
Source 2, the electromagnetic relay 3 being electrically connected with common power supply 1, the common power supply 1 of normally opened contact connection of the electromagnetic relay 3, electromagnetism
Relay 3 normally-closed contact connection stand-by power supply 2, the electromagnetic relay 3 movable contact connection electrical equipment, the electromagnetism after
Electric appliance 3 uses three normally opened contacts, three normally-closed contact, and wherein normally opened contact connects the electromagnetic relay 3 respectively with normally-closed contact all the way
Connect common power supply indicator 4 and stand-by power supply indicator light 5；3 coil of electromagnetic relay using 12V DC power, and electromagnetism after
Transformer 6 and rectifier 7, the coil-end of the electromagnetic relay 3 are connected between the coil terminals of electric appliance 3 and common power supply 1
It is sub to be also associated with voltage detection module 8 between common power supply 1.
The utility model uses three normally opened three normally closed electromagnetic relays 3, transformation after 220V AC are often powered with power supply 1
Device 6 can drop to 220V voltages in direct currents of the 12V again after rectified device 7 and be sent to 3 coil of electromagnetic relay, be powered using 12V DC
Electromagnetic relay 3 substantially without noise, relay is attracted at this time, then original normally opened contact is connected, (state is common electricity
Source 1 powers), normally-closed contact disconnects；Electromagnetic relay 3 discharges after common power supply 1 powers off, and electromagnetic relay 3 returns to original at this time
Carry out normally off, normally closed to be powered (namely stand-by power supply 2 is powered), normally opened contact disconnects.
Voltage detection module 8 is also associated between the coil terminals of the electromagnetic relay 3 and common power supply 1, when common
It is automatic to disconnect common power supply 1 and the connection of electromagnetic relay 3 during 1 brownout of power supply, it is powered using stand-by power supply 2.
When dual power supply is that common power supply 1 is powered, green indicator light can light on the left of dual power supply output terminal；When common electricity
When the power failure of source 1 switches to stand-by power supply 2, red indicating light can light on the right side of dual power supply output terminal.Convenient for observing at any time.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
