Because it is underground that ground network is embedded in, conventionally test carries out on ground.Can't the CSE reference electrode be placed on ground network and the interface that soil contacts during measurement, but be placed on ground surface directly over the ground network, or more farther place.The potential data of ground test has comprised that the deviation of introducing falls in IR in the measuring circuit, and the pipe to soil potential reading that measures is more negative than the current potential of ground network and the direct contact interface of soil.
The utility model content
The utility model technical problem to be solved is to overcome the defective that above-mentioned prior art exists, and a kind of grounding net of transformer substation anode loss protection remote control is provided, to eliminate the current potential of ground test
The deviation of introducing falls in IR, and can support many remote measurement equipment.
For this reason; The utility model adopts following technical scheme: grounding net of transformer substation anode loss protection remote control; It is characterized in that it comprises supervision control PC, GSM Modem, a plurality of remote measurement equipment and a plurality of pipeline test pile; Remote measurement equipment is connected with the pipeline test pile, remote measurement equipment access to mobile network, and GSM Modem is connected with supervision control PC; To keep watch on also access to mobile network of control PC, realize keeping watch on the exchanges data between control PC and the remote measurement equipment.
GSM Modem realizes the wireless access of PC, the exchanges data between realization and the remote measurement equipment.The system that considers is not high to the frequent degree of the operation of data collection and control, and the equipment room transmission of Information can consider to adopt the mode of short message (SMS), helps the reduction of operating cost.Keep watch on the control PC friendly man-machine interface is provided, the functions such as management of the demonstration of realization test data, the input of control command and equipment, parameter.
As the further technical scheme of the utility model; Described supervision control PC comprises single-chip microcomputer, gsm module, USART module and eeprom chip; Described single-chip microcomputer is connected with eeprom chip with described gsm module, USART module respectively; Described gsm module is connected to one and stores card, and described single-chip microcomputer is connected with remote measurement equipment, and described remote measurement equipment is made up of electric potential signal modulate circuit and circuit of measurement and control.Remote measurement equipment can be arranged on by the pipeline test pile, realizes measurement and measurement control to pipe to soil potential, and the information transmission between the control PC is realized and kept watch on to remote measurement and control equipment access to mobile network through the mobile network.
As the further technical scheme of the utility model, described pipeline test pile is connected to auxiliary test piece and anode.
The beneficial effect that the utlity model has: the deviation of introducing falls in the current potential IR that a) can eliminate ground test; B) can support many remote measurement equipment; C) can monitor ground network cathodic protection antiseptic effect in real time, avoid corrosion failure ground network.
Below in conjunction with Figure of description and embodiment the utility model is described further.
