中文摘要:
      时间域激发极化法技术规定,测量大地极化率参数必须要应用恒流电源供电,才能获得正确的极化率值,但由于研制激电法恒流供电电源难度较大、成本高,至今我国时域法的供电电源大部分仍是电压源供电。针对我国激电法观测系统应用电压源发送机的失误,作者研发了IPF-5000 5kW大功率恒流源发送机系统。经对比实验,该系统工作稳定,恒流性能良好,且较为轻便,可保障激电法正确测量。
英文摘要:
      Based on the technical manual of time domain IP method, it is necessary to use the constant current power supply to measure the parameters of the earth polarization. However, due to the difficulty and high cost of developing IP constant current power supply,currently, most of the power supply in time domain method is still a voltage source. Aiming at solving the problem, the authors developed a high-power constant current source transmitter system i.e., IPF-5000 5kW. By comparing the experiment results, this system is stable and has good performance of constant current. The system can ensure the accurate measurement of IP method.
