FAQ
Q: What are the interlocking regulations for bypass disconnectors in thermal power plants and substations?
A:
 The interlocking regulations for bypass disconnectors in thermal power plants and substations are as follows:
  • The bypass disconnector of each line can only be operated when the bypass circuit breaker is open and its bypass bus disconnector is closed. For the operation of the line bypass disconnector, it can only be operated when its outgoing line earthing switch is open.
  • The bypass bus-side disconnector of the bypass circuit breaker can only be operated when the bypass circuit breaker is open and the disconnector connected for bus tie operation is open.
  • The earthing switch on the bypass bus side of the bypass circuit can only be operated when the disconnector on the bypass bus side of the bypass circuit breaker is open.
  • The earthing switch on the bypass circuit breaker side of the bypass circuit can only be operated when the bypass circuit breaker and its bypass bus-side disconnector are open, and the disconnector connected for bus tie operation is open.
Q: How to Select Suitable Disconnectors Based on Altitude?
A:

In high-altitude areas, due to thin air, insulation distances need to be appropriately increased. Therefore, the following points should be considered during selection:

  • Rockwill Electric: DS7B-800D/5000, custom-designed for high-altitude applications, offers strong corrosion resistance and durability, adapts to complex outdoor environments, and features user-friendly operation with reliable safety interlock design.

  • Pinggao Electric: GW46-1100/6300, an ultra-high voltage (UHV) level product capable of providing sufficient insulation margin.

  • China XD Electric: GW47-1100/6300, also suitable for UHV environments and tested for plateau adaptability.

  • Siyuan Electric: GW5-G-252D/2000, though not at the UHV level, its improved design enhances performance under high-altitude conditions.

Comparison Points:

  • Insulation Distance: UHV-level models like GW46 and GW47 provide larger insulation distances, making them more suitable for high-altitude applications.

  • Altitude Correction: For non-UHV level products, it is necessary to refer to the altitude correction factors of specific models to ensure compliance with on-site conditions.

    Impact of DC Bias in Transformers at Renewable Energy Stations Near UHVDC Grounding ElectrodesWhen the grounding electrode of an Ultra-High-Voltage Direct Current (UHVDC) transmission system is located close to a renewable energy power station, the return current flowing through the earth can cause a rise in ground potential around the electrode area. This ground potential rise leads to a shift in the neutral-point potential of nearby power transformers, inducing DC bias (or DC offset) in their
