Why Does the Light of an Underground Xiangtan Electric Locomotive Become Dim?

2025-10-13

The underground Xiangtan electric locomotive is an essential piece of mining transport equipment, playing a key role in underground operations. However, sometimes operators may notice that the locomotive’s lights appear dim, which can affect both work efficiency and operational safety. This article explores the possible causes of dim lighting and provides practical solutions.

1. Power Supply Issues

A common cause of dim lights is an unstable power supply. During underground operation, the traction network voltage may drop, or the battery supply voltage may decrease, resulting in weak lighting. The solution is to ensure that the power source functions normally. Regular inspection and maintenance of power equipment help maintain a stable voltage output.

2. Poor Contact Between Current Collectors and Overhead Lines

For trolley-wire locomotives, poor contact between the current collector and the overhead wire can cause dim lights. Inconsistent contact reduces current transmission, directly affecting the lamp brightness. To fix this, check the contact condition regularly, clean the collector and wires, and repair any worn components to ensure smooth power delivery.

3. Faulty Parallel Lighting Resistors

The lighting system of a locomotive often includes parallel resistors. If one of these resistors is open-circuited, it may lead to partial dimming or failure of the lights. Regular inspection of the lighting circuit is necessary to confirm resistor continuity and performance. Replace any damaged resistors promptly to restore full brightness.

In conclusion, underground Xiangtan electric locomotive lights may become dim due to power supply issues, poor contact between the current collector and overhead line, or problems with parallel lighting resistors. Regular maintenance and inspection of the power system, electrical contacts, and lighting circuits are essential to ensure stable and bright illumination. Proper care helps maintain efficient and safe operation in underground mining environments.
