Filtration module of battery used in transformer substation environment temperature and humidity monitoring system

The invention discloses a filtration module of a battery used in a transformer substation environment temperature and humidity monitoring system. The filtration module of the battery used in the transformer substation environment temperature and humidity monitoring system comprises a battery body, a first resistor, a first capacitor, a second capacitor and a first inductor, wherein the two ends of the first resistor are connected with the positive pole of the battery body and the first inductor respectively, the other end of the first inductor is opposite to one end, connected with the first resistor, of the first inductor and is connected with a voltage output line, one end of the first capacitor and one end of the second capacitor are both connected to a circuit between the first resistor and the first inductor, and the other end of the first capacitor and the other end of the second capacitor are both grounded. When the battery body conducts power supplying, a filter circuit formed by the first capacitor and the second capacitor can filter part ripple waves, and therefore influence caused by the ripple waves on the environment temperature and humidity monitoring system can be reduced.
