Compared with prior art, the present invention has the following advantages:
1, whole system can be carried out every data acquisition and monitoring to low voltage power distribution networks such as rural power grids, has remedied at present for the rural power grids operational factor, especially the blank of residual current data acquisition monitoring aspect.
2, residual current transformer adopts the open type residual current transformer, because residual current current values under normal conditions is all very little, (being generally less than 100mA) and occuring single-phase or during two-phase ground connection, earth current can be very large, and the requirement that the open type residual current transformer is exported small-signal is sensitive and accurate, anti-impact of living large electric 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, make things convenient for the operator on duty to monitor in real time, grasp at any time the ruuning situation of electrical network, can in time process for accident.
4, platform district Computer Service platform can be by data analysis and the processing of software to uploading, so that the operator on duty can obtain relevant information more intuitively.
5, residual current transformer is connected to the earth connection (near neutral line place) of inducer for line outlet end of transformer, as long as the installation site is correct, the earth connection electric current just equals residual current (i.e. the leakage current of this transformer), therefore only need to adopt to comprise that the residual current transformer of an earth connection detects residual current, easy for installation a lot of with the zero-sequence transformer that comprises 4 outlets of employing (A phase, B phase, C phase and the neutral line).
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1; a kind of residual current remote data acquisition and operation monitoring system; this system is connected in the 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 the open type residual current transformer, be connected to the earth connection (near 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 under normal conditions is all very little, (being generally less than 100mA) and occuring single-phase or during two-phase ground connection, earth current can be very large, and the requirement that the open type residual current transformer is exported small-signal is sensitive and accurate, again anti-impact of living large electric current, can improve data precision, 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 with residual current and load monitoring device 2 equally.Residual current and load monitoring device 2 gather residual current data and network load data, and process by residual current transformer 11, electric power mutual-inductor 12 respectively.
