Background technology
In operation of power networks, for, situations such as Transfomer Substation Reconstruction, the maintenance of equipment, needing to set up mobile substation generation temporarily
Load is powered for original transformer station, mobile substation facility compact requires that rapid deployment is removed with tearing open, to mobile substation
The monitoring of accident resultant signal has been used up increasing one piece of accident resultant signal screen newly in former transformer station, and this will expend substantial amounts of manpower thing
Power, and dismounting bothers very much, as mobile substation is simply put into operation temporarily, will remove again in the short time, so newly-increased thing
Therefore resultant signal screen display is obtained and is bothered very much.
The content of the invention
A kind of micro transformer station integrated warning system is provided in order to solve the above-mentioned technical problem present invention, it is therefore an objective to solve to move
Dynamic transformer station expends a large amount of manpower and materials when disposing and tearing open and remove in former supervisory control of substation room installation and removal accident resultant signal screen,
Excessively troublesome problem.
It is micro transformer station integrated warning system of the present invention up to above-mentioned purpose, is made up of following structures：Charger, charger
Power to lithium battery group, lithium battery group is powered to two-position relay and 5V boost modules, two-position relay control involution is surveyed
Examination button, chimes of doom IC and power amplifier module, chimes of doom IC to power amplifier module sending signal, power amplifier module with raise
Sound device connects, and 5V boost modules are connected with voltage indicating circuit, and voltage indicating circuit is connected with LED light, two-position relay
Device is provided with input terminal.

2nd, it is standby：When alarm is not activated, two-position relay（DC24V-ST2-L2）In release conditions, 24V liters
Die block (LM2577) is in power failure state.5V boost modules（LM2577）Power supply is obtained from lithium battery group, output 5V voltages are supplied
To the cell voltage indicating circuit being made up of LM358, and shown by LED light.
3rd, alarm：By External input terminals introduce 220V DC signals series resistance to two-position relay adhesive
Coil power supply, relay adhesive, internal two groups of contact adhesives are respectively turned on two loops：
1）24V boost module power supplys are connected, and 24V boost modules start 24V power supplys to be provided for device.
2）Connect chimes of doom IC (KD9561), the 24V power supplys of power amplifier module (TDA2030), the 3.3V of chimes of doom IC
Reduction voltage circuit is made up of LM7808 and 1117-3.3, and now chimes of doom IC sends audio signal, Jing after power amplifier module amplifies
Alarm sound is sent by speaker.
4th, involution：After involution testing button is pressed, the involution coil power of connection two-position relay, coil magnetization, after
Electrical equipment discharges, and disconnects the power supply of lithium battery and 24V boost modules, chimes of doom IC and power amplifier module, and chimes of doom disappears, device
Switch to holding state.
