Insulation Monitoring and Fault Location in Non-coal Mines

Date:07-12  35  Belong to:SOLUTION
Sikcon relies on its complete products lines and excellent performance to be applied in the insulation monitoring project of China's three major non-ferrous metal mines. In this project, Sikcon's high-voltage insulation monitoring device was applied. The high-voltage insulation monitoring device is mainly used for automatic monitoring of high-voltage motors above 3kV after shutdown, replacing the traditional manual detection method of megohmmeters. It is used for insulation monitoring in damp and complex working conditions underground mines, which not only reduces labor intensity but also improves the safe operation and maintenance of high-voltage motors.

In addition, because the underground power grid system in mines is a neutral point ungrounded system (IT system), frequent dragging of mining machines and cables during mining operations poses a great challenge to the insulation performance of the power grid system. At the same time, the underground power grid system is complex, with large distributed capacitance and multiple power grid branches. Therefore, there is a strong demand for insulation monitoring and fault location products, as well as high requirements for product stability, measurement response time, and accuracy. Therefore, Sikcon's IFLS-600 insulation monitoring and fault location system has been highly recognized by end customers through on-site testing and application, especially in frequency converter power grid systems. The stability and measurement response advantages of IFLS-600 are more prominent, and its measurement performance is better than many similar products of European brands.
 

Application scenarios

  • Petroleum and Chemical
    The petrochemical industry has been one of the most important industries in the past half-century, closely related to human production and life. In the petrochemical industry, electrical equipment is widely used, including various high-voltage and low-voltage motors, which drive fans, compressors, pumps and other equipment. In addition, the system also contains a large number of high-power DC loads and nonlinear loads, such as frequency converters, UPS, rectifier devices, etc. These load types are complex and generate a large amount of harmonics, which further lead to increased losses of equipment such as motors and transformers, accelerate aging, and even cause power system faults ‌. Therefore, there are very high requirements for the design and operational safety of the power supply system. Therefore, preventive monitoring of electrical systems in the petrochemical industry is a must for modern production.

  • Mining
    在矿山系统中,有很大一部分原因的生产状况是因为设备线路绝缘老化、电气或电机绝缘故障导致。因此电气设备绝缘性能的预防性监测在日常运维和电气保养方面至关重要,矿山井下主要动力为电机,但当前矿山系统的电机绝缘性能预防性监测依然采取传统的监测方式,程序复杂,工作强度大,如果涉及高压电机,人工危险性高。
