Analysis of Abnormal Causes of High-Voltage Cable Grounding Circulation and Typical Cases

I. Introduction to Cable Grounding Loop CurrentCables rated 110 kV and above use a single-core structure. The alternating magnetic field generated by the operating current induces a voltage on the metallic sheath. If the sheath forms a closed circuit through the earth, a grounding loop current will flow on the metallic sheath. Excessive grounding loop current (loop current exceeding 50 A, more than 20% of the load current, or a ratio of maximum-to-minimum phase current greater than 3) not only a

Considerations and Recommendations for Flame-Retardant Selection of High-Voltage Cables

1.Flame-Retardant Cable Classification StandardsThe flame-retardant standard system is divided into two main categories. The first category follows the "Classification of Burning Behavior for Electric and Optical Fiber Cables" GB 31247. Cables complying with this standard system are widely used in densely populated areas such as high-speed railways and subways. This standard imposes strict requirements on parameters such as smoke density, heat release, and total smoke production, and cables typi

Repair of high-voltage cable metallic sheaths

I. Functions of Metallic Sheaths and Necessity of RepairThe metallic sheath of high-voltage cables is a metal shielding structure laid outside the insulation layer, including types such as lead sheaths, aluminum sheaths, and steel wire armor. Its core functions include mechanical protection (resisting external impact and compression), electrochemical corrosion protection (isolating moisture and soil pollutants), electromagnetic shielding (reducing electromagnetic interference to the environment)

What factors need to be considered when designing a transformer?

Transformer design is a complex process that requires consideration of multiple factors to ensure safe and efficient operation. In addition, compliance with international and local regulations is essential to guarantee that transformers meet safety and performance standards. Below are key factors to consider in transformer design and the relevant regulations to follow:Transformer Design Factors: Voltage and Frequency: Determine the input and output voltage levels and the operating frequency. The

What failure modes are possible in a transformer? How to identify and fix these failures?

Transformers are critical components in power systems, and various failure modes can affect their operation. Timely identification and resolution of these failure modes are essential to prevent costly downtime and ensure system reliability. Below are some common transformer failure modes, along with methods to identify and address them: Insulation FailureIdentification: Insulation failure leads to decreased insulation resistance, which can be detected through insulation resistance testing (megge

A hybrid DC circuit breaker

A hybrid DC circuit breaker

Most DC molded-case circuit breakers use natural air arc extinction, and there are typically two arc extinguishing methods: one is conventional opening and closing, where the contacts axially stretch the arc, while the conductive circuit generates a magnetic field that bends and elongates the arc, pulling it lengthwise perpendicular to the arc axis. This not only increases the arc length but also induces lateral motion, enabling air cooling to achieve arc extinction.The other method involves the
