Electric exploration signal transmitter

Abstract

This invention discloses a sender of electric exploration signals, which applies IPM as the power conversion device to carry out intelligent control matched with a micro-controller, designs a dead zone time adjusting circuit at the input end of the drive isolation circuit control signals composed of a multiple analog switch, a resistor, a capacitor and OR gate and NOT-gate, a thermistor is set on the IPM surface and is connected with a temperature reducing system and a micro-controller to control the on and off of the fan intelligently by the micro-controller.

Description

technical field [0001] The invention relates to an electrical prospecting signal transmitter, in particular to an electrical prospecting signal transmitter for geological prospecting. Background technique [0002] Existing electrical prospecting signal transmitters generally use silicon controlled rectifiers or IGBTs as inverters, which have the following defects: first, the integration level is not high, and additional control and protection circuits are required, resulting in a bulky system; second, There is no overheating protection; the third is that the protection speed is not timely; the fourth is that troubleshooting is difficult; the fifth is that the dead time cannot be adjusted; Most of the current is 100mA ~ 200mA, the power consumption is relatively large, and the cooling fan is not adjustable, resulting in excessive power consumption of the whole machine. Contents of the invention [0003] The purpose of the present invention is to provide an electrical prosp...
