Breath (2.f) is stored in the memory module, the good gas concentration measurement information of the aggregation process of processor module, warning message,
The information such as equipment running status (2.g) are sent to the communication module；2) processor module processes what the communication module was issued
Command information (2.h)；3) processor module operational factor is arranged, and command information (2.d) is issued the communication module；
The storage module be used for storage information (2.f), including concentration of ozone gas metrical information, warning message, can store to
Few 3 months quantity of information；When information is had access to, the information of transferring storage from the storage module by the processor module
(2.f)；
The display module is used for showing current information and historical data information (2.e), runs including the communication server
State, concentration of ozone gas metrical information；
The power module is powered to communication module, processor module, storage module, display module respectively.
5. power distribution automation ring main unit partial discharge monitoring system according to claim 4, it is characterised in that the distribution
Automatization's ring main unit partial discharge monitoring system will give the distribution on concentration of ozone gas metrical information, warning message automatic
The mode for changing terminal (3) has two kinds：One kind is power distribution automation ring main unit partial discharge monitoring system according to the communication server (2)
The process cycle of setting, after regularly finish information processing on deliver letters breath (2.i) to the distribution power automation terminal (3)；Another
Kind it is to be issued to transfer command information (2.j) and put to power distribution automation ring main unit local by the distribution power automation terminal (3)
Pyroelectric monitor system, after the power distribution automation ring main unit partial discharge monitoring system receives command information (2.j), carries out at information
Science and engineering is made, information processing finish after on deliver letters breath (2.i) to the distribution power automation terminal (3).
