Q:What is the SF6 ring main unit?

A:An SF6 ring main unit is a key component in medium - voltage power distribution systems. It uses SF6 gas for insulation and arc - quenching. Compact in design, it integrates functions like switching, protection, and connection. It ensures stable power supply in various scenarios, from urban grids to industrial zones, with high reliability and safety.

Q:How is SF6 measured?

A:SF6 can be measured in several ways. One common method is using a gas density monitor to measure the density of SF6 in a closed system. Another is via a pressure gauge to check its pressure, as pressure is related to gas content. Additionally, infrared spectroscopy can be used to analyze the concentration of SF6 in the air.

Q:What is the purpose of RMU?

A:The Ring Main Unit (RMU) serves crucial purposes in electrical distribution. It enables efficient power distribution in urban areas, industrial complexes, and commercial buildings. RMUs house switches, fuses, and circuit breakers to control and protect electrical circuits. They simplify connections between power sources and consumers, enhance grid reliability, and help manage load distribution, ensuring stable power supply.

Impact Analysis of Voltage Transformer Installation on Line Side vs. Load Side of Power Inlet Circuit Breaker for (ATS)
Impact Analysis of Voltage Transformer Installation on Line Side vs. Load Side of Power Inlet Circuit Breaker for (ATS)
Automatic backup switching (ABTS) devices are core components ensuring the safe, reliable, and stable operation of factory power grids. Their startup logic strictly follows the dual criteria of "loss of voltage in the working power supply + no - current detection", effectively avoiding misjudgments caused by secondary disconnection of voltage transformers (VTs) or maloperations of ABTS due to secondary circuit faults of current transformers (CTs). The activation condition requires both "no volta

Case Analysis of Abnormal Secondary Circuits in Voltage Transformers
Case Analysis of Abnormal Secondary Circuits in Voltage Transformers
1. Fault SituationIn September 2023, as a front - line fault maintenance worker, I detected abnormal voltage on the 10kV Section I bus of a substation during monitoring duty and informed the operation and maintenance team. The monitoring system showed: U0 = 0 kV, Ua = 6.06 kV, Ub = 5.93 kV, Uc = 6.05 kV, Uab = 10.05 kV, Ubc = 5.94 kVMy team and I rushed to the site. We suspected the secondary air circuit breaker of the 10kV Section I bus voltage transformer was closed and found the U - phase fus
