 What are the key points for the selection of outdoor vacuum reclosers?

  • System Parameter Matching: Choose a recloser that matches the rated voltage, rated current, and short-circuit current levels of the power system. Ensure that the rated voltage of the recloser is equal to or higher than the system voltage, the rated current meets the requirements of the line load current, and the rated short-circuit breaking and making currents are greater than the maximum possible short-circuit current in the system.

  • Reclosing Performance Requirements: Consider the specific requirements of the power system for the reclosing function, such as the number of reclosures, reclosing time intervals, and reclosing success rate. Based on different application scenarios and power supply reliability requirements, select a recloser with appropriate reclosing performance. For example, for critical power supply lines, a recloser with a higher number of reclosures and flexible reclosing time intervals may be required.

  • Type of Operating Mechanism: Choose an appropriate operating mechanism based on actual needs. Spring-operated mechanisms are suitable for outdoor environments where high reliability is required and maintenance conditions are relatively poor. Permanent magnet-operated mechanisms are better suited for applications requiring high action speed and frequent operations.

  • Environmental Adaptability: Given the harsh conditions of outdoor environments, consider the environmental adaptability of the recloser. This includes weather resistance, pollution resistance, and water and dustproof performance. Selecting a recloser with good environmental adaptability ensures stable performance during long-term outdoor operation.

  • Brand and Quality: Choose well-known brands and high-quality recloser products. These products have strict quality control systems in design, manufacturing, and testing, ensuring the performance and reliability of the product. Additionally, good after-sales service is an important factor to consider when choosing a brand, as it ensures timely resolution of issues that may arise during equipment operation.

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

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

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 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
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
