High-power direct current IP measuring system with direct feed

Abstract

The invention discloses a high-power direct current IP measuring system with direct feed. The high-power direct current IP measuring system comprises a power supply, a transmitter and a receiver matched with the transmitter. The power supply is connected with the power source end of the transmitter, the power supply is a high-voltage and high-power power source based on a battery, and the transmitter is an intermittent transmitting transmitter. The power supply is formed by connecting a plurality of battery modules in series, wherein fault units of the battery modules can be automatically cut out of the series sequence. The power supply comprises a direct current high-voltage power supply circuit which comprises a low-voltage battery and an isolation DC-DC boosting module, and the low-voltage battery is connected with the power source end of the transmitter through the isolation DC-DC boosting module. The transmitter is provided with a controlled electronic switch K with the load switching function. The power supplying current is large, the transmitting power of the transmitter is high, and the measuring effect is good. The power supplying fault tolerance is good, and reliability is high. The power supplying efficiency is high, energy sources are saved, carrying is convenient, oil does not need to be burned, running cost is low, and the high-power direct current IP measuring system is environmentally friendly.

Description

technical field [0001] The invention relates to the field of high-power IP exploration, in particular to a directly powered high-power DC IP measurement system. Background technique [0002] With the increasing demand for non-ferrous metals in the international and domestic markets, a new round of mining development is booming. However, the exposed ores on the surface in areas with better geographical conditions in my country have basically been found. The current prospecting objects are mainly concealed and Deep buried mines increase the difficulty of geological exploration and put forward new requirements for geophysical exploration. With the advancement of science and technology, geophysical prospecting instruments are constantly being updated, and new, high-power, and stable-performance geophysical instruments are constantly emerging. [0003] Electrical prospecting (referred to as electrical method) is based on the differences in the electrical properties of various roc...

Problems solved by technology

③Balanced load: Since the high-voltage rectified power supply of the high-power transmitter is provided by the 220V AC power from the generator through transformation and rectification, the high-voltage DC power supplies power to the ground with a square wave signal with a duty ratio of 1:1 through the bridge. , during the time when the power supply is stopped, the generator is in the no-load state, which is prone to speeding, which is unfavorable to the generator

[0018] 2. Low efficiency and high energy consumption:

[0020] 3. Poor power quality:

[0021] Because it is impossible to ensure that the balanced load impedance is exactly the same as the resistance to ground, and there are problems such as rectified power supply filtering, the input power supply voltage still fluctuates to a certain extent, and the power supply obtained by the transmitter is not pure, which will have a certain adverse effect on the detection.
