The invention relates to a power distribution net box type
transformer environmental parameters on-line
monitoring system which includes the steps that aiming at any one of box-type
transformer substations, the power distribution net box type
transformer environmental parameters on-line
monitoring system is provided with a plurality of sensors, wherein at least the temperature of a
high pressure charged body in the environmental parameters of the box-type transformer substations, the
high frequency partial discharge, the temperature and
humidity in the box-type substation are monitored correspondingly by the sensors, and the monitored data of the various sensors are received and sent to a front-end
data acquisition unit of a monitoring center based on a wired or
wireless communication mode. The
data processing server device of the monitoring center carries out the storage and
processing analysis for the received data to generate a real-time
dynamic monitoring curve and produces an audible and visual alarm when the monitored data exceed a set threshold value, and meanwhile the alarm information can notify attendants in the relevant areas in a
text message form, so that the time of
incident response is shortened and the economic loss is reduced.
