What is a GIS combined coil?

2021-11-04

   GIS Combined Coil Abbreviation for gas-insulated metal-enclosed switchgear. GIS combined coils usually refer to circular wire windings. Common coil applications include motors, conductors, transformers, and ring antennas. Coils in circuits represent inductance. Wires are wound one by one, and the wires are insulated from each other. Insulation can include air cores, iron cores, or magnetic powder cores, referred to as inductors. GIS combined coil inductors can be divided into fixed inductors and variable inductors. Fixed inductors are called inductors or coils. The unit is Henry (h), millihenry (mH), microhenry (uh), 1h=103mh=106uh.


   GIS Combined Coil It is a digital, compact, and intelligent combination. The main components of the GIS combined coil are: intelligent terminal, circuit breaker, isolator, grounding switch, busbar, electronic voltage transformer, electronic current transformer, lightning arrester, and infeed system, etc. This series is the main equipment of the intelligent digital substation in the smart grid, with small size, large design margin, small footprint, flexible configuration, easy installation, strong environmental adaptability, and less maintenance work to improve safety and reliability. The maintenance interval of the main components should not be less than 25 years. Using standard component block layout, the layout is flexible and easy to expand, meeting various main connection requirements. The GIS combined coil is suitable for 145kV (below 126kV) power systems and is widely used in power plants, substations, chemical plants, steel plants, mines, petroleum, and new energy industries.

GIS Combined Coil Product Characteristics


1. Uses electronic transformers and intelligent terminals with self-diagnosis.


2. The product uses sensors to monitor the gas chamber status of the equipment in real time. Measured parameters include gas pressure, temperature, and trace moisture content. In addition, it also monitors the operating mechanism operating current, number of operations, and braking coil current of the core equipment circuit breaker. Data collection helps to perform collection, integration, analysis, and judgment through fiber optic networks, and operation instructions, thereby optimizing the operation of the entire power system.


3. The interception performance breakthrough performance circuit breaker has the characteristics of "self-energy" and "thermal expansion".


4. The GIS combined coil product adopts a three-phase industrial sub-design, with a single bay width of only 0.8 meters. The all-aluminum shell structure is lightweight, with low loss, low noise, and low factory requirements.


5. The GIS combined coil is easy to install and maintain: the product adopts overall transportation of the bay, and the "block principle structure" makes installation convenient and the cycle short.


6. Good sealing performance. The product adopts a double-seal structure, and the annual leakage rate is far less than 0.5%.


7. The circuit breaker has a mature mechanism, three-phase mechanical linkage, oil-free, gas-free, high reliability, and more than 10 years of grid operation experience.


       8. GIS Combined Coil Design and manufacturing meet the requirements.
