Abstract

The invention relates to a subsection intelligent controller for an underground electric locomotive string, which belongs to the technical field of controller structures and comprises a control switch. The input end of the control switch is connected with a power supply, a Hall current transformer is arranged between the power supply and the control switch, the control switch comprises a digital logic circuit and a transistor IGBT, the output end of the IGBT is connected with the string, a gate pole of the IGBT is connected with the output end of an oscillator and a rail connected with the ground, the output end of the oscillator is connected with an inductor which is connected with the string, a capacitor is installed in a locomotive on the rail, and the capacitor is connected with the string through an electric arc. The subsection intelligent controller is reasonable in circuit design and capable of shrinking string electrification range as much as possible, shortens string electrification time and greatly reduces accident incidence.

Description

technical field

[0001] The invention relates to a segmented intelligent controller for underground electric locomotives, and belongs to the technical field of controller structures. Background technique

[0002] As the main transportation equipment in underground mines, DC electric locomotives are widely used in various places. Due to the narrow mine tunnels and humid air, people and locomotives pass in the same tunnel, and it is easy for people to touch the wires by mistake and cause electric shock accidents, which poses a threat to safety management. Work brings difficulty. Contents of the invention

[0003] The object of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a kind of structure and circuit design that is reasonable, can minimize the charging range of the wire, shorten the charging time of the wire, and greatly reduce the accident rate. segment intelligent controller.

[0004] The present invention is achieved ...
