In the power supply system of the automatic meteorological station, an air switch, a power supply lightning protector, a switching power supply, a storage battery, an inverter and a deconcentrator are electrically connected according to requirements, the direct current output end of the switching power supply is connected with the deconcentrator and the direct current input end of the inverter in parallel, the alternating current output end of the inverter is connected with the deconcentrator, and the deconcentrator continuously outputs alternating current and direct current. When the commercial power is cut off, the storage battery can be used for continuously providing alternating current and direct current for the automatic weather station equipment.

Description

AC/DC double-output backup power supply for automatic meteorological station

Technical Field

The utility model relates to an automatic weather station backup power with output 12V direct current and 220V alternating current can continuously provide required 12V and 220V power supply for automatic weather station equipment under the commercial power outage condition.

Background

At present, the well-known backup power supplies of the automatic weather station are all 12V direct current single output and mainly comprise a switching power supply and a storage battery, 220V mains supply is connected into the switching power supply and converted into 12V direct current output and 13.8V direct current output, 12V directly supplies power for the automatic station system, 13.8V is connected with the storage battery to charge the storage battery, and when the mains supply is powered off, the storage battery is automatically converted into the storage battery to supply power, so that the continuous work of 12V direct current power supply equipment of the automatic weather station is realized. However, besides the 12V dc power supply device, the automatic weather station device also has a device that needs 220V ac power supply, for example, the precipitation weather phenomenon instrument sensor adopts 220V ac power supply, and these devices can only directly use the commercial power supply to work at present, and when the commercial power is cut off, the devices cannot work, so that the related weather observation data is lack of measurement, and the integrity and usability of the automatic weather station data are seriously affected.

Disclosure of Invention

In order to solve current automatic weather station backup power only has 12V direct current single output, can't satisfy the backup power supply demand of all equipment in automatic weather station, the utility model provides an automatic weather station alternating current-direct current dual output backup power with simultaneous output 12V direct current and 220V alternating current to when satisfying the commercial power outage, automatic weather station equipment is to the backup power supply demand of 12V direct current and 220V alternating current.

The utility model provides a technical scheme that its technical problem adopted is: A12V direct current-to-220V alternating current inverter is connected in parallel with a switching power supply and a 12V direct current output end of a standby power supply of the current automatic meteorological station, the positive and negative poles of the direct current input end of the inverter are connected with the positive and negative poles of 12V output of the switching power supply through a 12V direct current deconcentrator, and the 220V output end of the inverter is connected with a zero-live wire wiring deconcentrator for connecting 220V alternating current power supply equipment. When the commercial power is cut off, the output is automatically switched to the storage battery for power supply output, 12V direct current is supplied continuously, 220V alternating current is continuously output after inversion of the inverter for the automatic weather station equipment to use, the integrity and the usability of the data of the automatic weather station are ensured, and the purpose that the automatic weather station equipment can continuously work without being influenced by the commercial power is achieved.

The utility model has the advantages that: the automatic power supply device has the advantages that the 12V direct current required by the automatic weather station can be continuously supplied, meanwhile, the 220V alternating current can be continuously output, especially, the backup supply requirement of the automatic weather station on the alternating current is met, the automatic weather station is not influenced by the power failure of the mains supply, the structure is simple, the safety is high, the realization is easy, and the work is reliable.
