Three, if meet thunderstorm weather or air humidity big, when the person during, might discharge to the person and cause meter reading personnel's fortuitous casualty accident because of high-tension electricity too closely take place distance near high-tension bus-bar or near the high pressure measurement device;
Four, manually ascend a height and check meter, written notes cause the continuous data misalignment easily soon.
Summary of the invention
The technical problems to be solved in the utility model is, overcome the defective that measuring apparatus exists on the present ultra-high-tension power transmission line, provide a kind of and stand in the designation data that just can directly read watt-hour meter on the high-voltage power metering device on the ground, need not the professional and ascend a height and check meter, reduce labor intensity, the generation, work safety, data of avoiding the personal accident casualty accident accurately, infrared copy meter high-voltage power metering device reliably.
The technical scheme that the utility model technical solution is adopted is:
This infrared ray meter reading high-voltage power metering device, comprise: three-phase high-voltage line A, B, C, and the voltage transformer pt that links to each other with triple-phase line A, B, C, current transformer CT, it is characterized in that: set up one and voltage transformer pt, the three-phase electronic multifunctional electric energy meter that the output terminal of current transformer CT links to each other reaches with matching used the checking meter of three-phase electronic multifunctional electric energy meter and uses palm PC.Three-phase high-voltage line A, B, C become 6 kilovolts of electric system or 10 kilovolts of high voltages into standard 100V low-voltage through voltage transformer pt; Through triple-phase line current transformer CT the little electric current 5 that the electric current in the high-voltage system becomes low-voltage standards is pacified.Pressure-wire a, the b that the secondary side of voltage transformer pt is drawn, c are amplified to A/D converter through voltage sampling module, buffering, the electric current line that current transformer CT1, CT2 secondary side are drawn is through current sampling module, buffering is amplified to A/D converter, to output, output terminal is respectively RS485 interface, LCD demonstration, telemechanical output, infrared emission, infrared reception through digital integrated circuit, CPU; Infrared emission and receive window are set in the palm PC.This infrared ray meter reading high-voltage power metering device is applicable to the metering of the high voltage electric energy of 6 kilovolts or 10 kilovolts two electric pressures, can be installed on the ultra-high-tension power transmission line or electric power pylon apart from tens centimeters of ultra-high-tension power transmission lines, working environment is not had specific (special) requirements.The meter reading personnel stands in identity distance infrared ray meter reading high-voltage power metering device 8-10 rice, ground, and hand-held palm PC receives the data message that the three-phase electronic multifunctional electric energy meter sends at a distance, can carry out remote remote measurement electric energy meter continuous data.
Infrared ray meter reading high-voltage power metering device of the present utility model utilizes palm PC to receive the data message that the three-phase electronic multifunctional electric energy meter sends at a distance, thereby realizes remote remote measurement electric energy meter continuous data.Therefore overcome above-mentioned defective, utilized infrared ray meter reading high-voltage power metering device of the present utility model, the advantage that is had is:
(1) stands in the designation data that just can directly read watt-hour meter on the high-voltage power metering device on the ground.
(2) reduce labor intensity, avoid the generation of personal accident casualty accident.
(3) need not the professional ascends a height and checks meter.
(4) utilize palm PC to check meter, work safety, data are accurately, reliably.
