Abstract

The invention discloses a four-electrode double-electromagnetic-transmitter system. The system comprises a first transmitter, a second transmitter, a first power supply line, a second power supply line, a third power supply line, a first electrode, a second electrode, a third electrode, and a fourth electrode. The first and second transmitters are connected through the first and second power supply lines. The first electrode is electrically connected with the first transmitter, and the second electrode is electrically connected with the second transmitter. The first transmitter is electrically connected with the fourth electrode through the third power supply line, and the second transmitter is electrically connected with the third electrode through the third power transmission line. The first and second transmitters cooperate with each other, so as to enable a current waveform to be transmitted outwards through the above four electrodes. According to the invention, the currents passing through two twisted power supply wires of the third power supply line are equal and are opposite in direction, and the formed electromagnetic fields are counteracted, thereby reducing the impact on the transmission current from the parasitic inductance of the power supply lines. The system can emit a high-frequency current.

Description

technical field [0001] The invention relates to the field of detection technology, in particular to a four-electrode double electromagnetic transmitter system. Background technique [0002] Controlled source electromagnetic detection plays a very important role in solid mineral detection, offshore oil and gas exploration and submarine engineering evaluation. As the artificial excitation field source of the controllable source electromagnetic field in the controllable source electromagnetic detection, the controllable source electromagnetic transmitter is one of the hardware foundations of the controllable source electromagnetic detection method, and is also an important link in the entire controllable source electromagnetic detection system. refer to figure 1 Shown is a schematic structural diagram of a traditional electromagnetic transmitter system. A traditional electromagnetic transmitter system usually includes a diesel generator 01, an AC / DC rectifier module 02, a tra...
