Technical Field

The invention relates to the technical field of material conveying, in particular to a power supply system for a long-distance belt conveyor.

Background

At present, belt conveyors comprise common flat belts and tubular conveyors, and are commonly used for mining and transportation of mines; the invention mainly aims at long-distance common belt conveyors and pipe belt conveyors, the distance of transport is from several kilometers to dozens of kilometers, the low-voltage (lighting, detection, alarm, stretch switch, material flow, material level and the like) power supply is generally carried out by adopting a mode of leading a power supply from a fixed transfer station or a power supply point as a starting point and laying cables along the way, the distance between each transfer station or the fixed power supply point is generally more than several kilometers during long-distance transportation, the power supply mode causes serious voltage drop far away from the fixed power supply end to cause electric energy waste, and the cable selection diameter is large and the cost is high; once the main line circuit has a problem, the influence distance is long, and the workload of circuit maintenance is large.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: a power supply system for a long-distance belt conveyor is provided, which is low in cost and low in energy consumption.

The solution of the invention is realized by the following steps: a power supply system for a remote belt conveyor comprises a plurality of remotely distributed transfer stations, wherein distributed power sources are arranged between the transfer stations.

On the basis, a plurality of distributed power supplies are arranged between adjacent transfer stations.

On the basis, the larger the distance between the adjacent transfer stations is, the larger the number of distributed power sources is.

On the basis of the above, the more power supply facilities are arranged between the adjacent transfer stations, the more distributed power sources are arranged.

According to the technical scheme, the technical scheme provided by the invention has the following advantages:

the invention provides a power supply system for a long-distance belt conveyor, which comprises a plurality of long-distance distributed transfer stations, wherein a distributed power supply is arranged between the transfer stations. Therefore, the power supply system reduces the cable model selection diameter and reduces the engineering cost; the voltage drop of the circuit and the electric energy loss (long distance) are reduced, and energy is saved; the circuit fault has small influence range and is easy to overhaul.
