Embodiment
With reference to Fig. 1, provide a kind of intelligent substation patrol method, it comprises step: 1) select a predetermined detection area circuit; 2) checkout gear by installing near the high-voltage switch gear of this region wire diagnoses its opening and closing movement state, and carry out signal transacting, described checkout gear has: switch folding position transducer 41, for measuring folding or the vibration of described high-voltage switch gear 1; Temperature sensor 8, for measuring the temperature value at high-voltage switch gear place; Magnetometer 10, for measuring the AC alternating magnetic field intensity that region wire produces; And processor 4, connect described switch folding position transducer 41, temperature sensor 8 and magnetometer 10 to carry out signal conversion and process; 3) process the data obtained far-end is transferred to transformer station Yun Jian center.
In one embodiment, accelerometer selected by switch folding position transducer, for measuring the displacement of high-voltage switch gear respectively and be converted to charge signal to processor 4 on the x, y, z direction of three-dimensional planar.
In one embodiment, folding position transducer 41 is electric charge output type accelerometer or low-impedance voltage output type (IEPE) accelerometer.To produce high-speed sampling value.Traditional piezoelectric accelerometer exports a charge signal be directly proportional to acceleration by inner sensitive core body.The high impedance charge signal that in actual use, transducer exports must convert thereof into voltage signal in low impedance by secondary meter and could read.Because high impedance charge signal is very easy to be interfered, so the Signal transmissions between transducer to secondary meter must use low noise shielded type cable.Because the serviceability temperature of electronic device is limited in scope, so the measurement under hot environment generally still uses electric charge output type.The ICP type piezoelectric accelerometer that IEPE type piezoelectric accelerometer is namely usually alleged.The electric charge that piezoelectric transducer transducer exports converts low-impedance voltage to by the preamplifier being contained in sensor internal and exports.IEPE type transducer is generally two wires output form, namely adopts constant current voltage fed; Direct current supply and signal use same single line.Usual direct current part passes through high pass filter elimination at the output of constant-current power supply.The great advantage of IEPE type transducer is that measures signal quality is good, noise is little, anti-external interference ability strong and telemeasurement, particularly novel data actuation is much equipped with constant current voltage source, therefore, IEPE transducer directly can be connected with data actuation and without any need for other secondary meter.In vibration-testing, IEPE transducer replaces traditional electric charge output type piezoelectric accelerometer gradually.
