Technical field
The present invention relates to a kind of electric network information treatment system, especially relate to a kind of residual current remote data acquisition and operation monitoring system.
Background technology
The data acquisition of a residual current distant place and operation monitoring are carried out in requirement according to national grid agriculture [2011] No. 66 files.What propose according to " Shanghai Electric Power Co " 12 " program for the development of science and technology " considers power distribution network security reliability, economy and risk outline, disposes and strengthens Serving for Rural Electrical Safety work, promote the rural power service environment of creating policy.State's net companies ask carries out follow-up of quality and statistics to the operating aftercurrent action protecting equipment of rural power grids, agriculture net platform region is equipped with data acquisition based on residual current and supervising device and can realizes monitoring the parameters of the reliable electricity consumption of rural safe and data summarization and provide necessary protection.But at present to this low voltage power distribution network of rural power grids, also lack effective data acquisition and operation monitoring means.
Summary of the invention
Object of the present invention is exactly provide a kind of data acquisition accurately convenient, stable residual current remote data acquisition and operation monitoring system to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of residual current remote data acquisition and operation monitoring system, this system is connected to low voltage power distribution network, described system comprises residual current transformer, electric power mutual-inductor, residual current and load monitoring device, wireless communication apparatus, alarm protecting apparatus and platform district Computer Service platform, described residual current transformer and electric power mutual-inductor are all connected to the inducer for line outlet end of transformer of low voltage power distribution network, described residual current and load monitoring device respectively with residual current transformer, electric power mutual-inductor, wireless communication apparatus is connected with alarm protecting apparatus, described platform district Computer Service platform connects wireless communication apparatus by wireless network,
Residual current and load monitoring device gather residual current data and network load data respectively by residual current transformer, electric power mutual-inductor; after treatment by wireless communication apparatus by wireless network by data upload to platform district Computer Service platform; receive the command information from platform district Computer Service platform simultaneously; if the residual current data that residual current and load monitoring device collect and network load data exceed alarm and protection value; then reported to the police by alarm protecting apparatus, and protection act is carried out to low voltage power distribution network.
Described residual current transformer is connected on the earth connection of inducer for line outlet end of transformer, and this residual current transformer is open type residual current transformer;

Described data outputting module exports data by the form of form, curve or figure.
Compared with prior art, the present invention has the following advantages:
1, whole system can carry out the collection and monitor of every data to low voltage power distribution networks such as rural power grids, compensate at present for rural power grids operational factor, the especially blank of the acquisition monitoring aspect of residual current data.
2, residual current transformer adopts open type residual current transformer, because residual current current values is under normal conditions all very little, (being generally less than 100mA) and when there is single-phase or two-phase ground connection, earth current can be very large, and the output of open type residual current transformer is sensitive and accurate to the requirement of small-signal, anti-impact of living big current, can improve data precision, guaranteed security of operation again.
3, adopt wireless network that data are transferred to platform district Computer Service platform in real time, facilitate operator on duty to monitor in real time, grasp the ruuning situation of electrical network at any time, can process in time for accident.
4, platform district Computer Service platform can, by software to the data analysis uploaded and process, make operator on duty can obtain relevant information more intuitively.
5, residual current transformer is connected to the earth connection (close to neutral line place) of inducer for line outlet end of transformer, as long as installation site is correct, earth connection electric current just equals residual current (i.e. the leakage current of this transformer), therefore only need to adopt the residual current transformer comprising an earth connection to detect residual current, much easy for installation with the zero-sequence transformer comprising employing 4 outlets (A phase, B phase, C phase and the neutral line).
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1; a kind of residual current remote data acquisition and operation monitoring system; this system is connected to countryside low-voltage electric distribution network network, comprises residual current transformer 11, electric power mutual-inductor 12, residual current and load monitoring device 2, wireless communication apparatus 4, alarm protecting apparatus 3 and platform district Computer Service platform 5.
Wherein, residual current transformer 11 adopts open type residual current transformer, be connected to the earth connection (close to neutral line place) of countryside low-voltage electric distribution network network inducer for line outlet end of transformer, be connected with residual current and load monitoring device 2 simultaneously, because residual current current values is under normal conditions all very little, (being generally less than 100mA) and when there is single-phase or two-phase ground connection, earth current can be very large, and the output of open type residual current transformer is sensitive and accurate to the requirement of small-signal, anti-impact of living big current again, data precision can be improved, guaranteed security of operation.Electric power mutual-inductor 12 is connected on the live wire of inducer for line outlet end of transformer, is connected equally with residual current and load monitoring device 2.Residual current and load monitoring device 2 gather residual current data and network load data, row relax of going forward side by side respectively by residual current transformer 11, electric power mutual-inductor 12.
Residual current and load monitoring device 2 are connected with wireless communication apparatus 4 and alarm protecting apparatus 3 respectively, and wireless communication apparatus 4 is connected to platform district Computer Service platform 5 by GPRS wireless network.Residual current and load monitoring device 2 gather and after deal with data, GPRS wireless network is passed through by data upload to platform district Computer Service platform 5 by wireless communication apparatus 4, operator on duty is facilitated to monitor in real time, grasp the ruuning situation of electrical network at any time, can process in time for accident, simultaneously by wireless network, residual current and load monitoring device 2 can receive the command information from platform district Computer Service platform at any time.If the residual current data that residual current and load monitoring device 2 collect and network load data exceed alarm and protection value, then reported to the police by alarm protecting apparatus 3, and protection act is carried out to low voltage power distribution network, ensure the security of operation of electrical network.
