Introduction of SF6 circuit breaker:

SF6 circuit breaker is a kind of high-voltage power switchgear with sulfur hexafluoride (SF6) gas as insulation medium and arc extinguishing medium. It is commonly used in power transmission and distribution systems for controlling the opening and breaking of circuits and protecting the safety of power systems.

Main features of SF6 circuit breaker:

1.  superior  insulation  performance:  sulfur  hexafluoride  gas  has  high  electrical insulation strength, which can effectively prevent short circuit caused by electric arc.

2. strong arc extinguishing ability: SF6 gas can quickly absorb the arc energy, so that the arc is quickly extinguished to prevent the fault from expanding.

3. Small size and compact structure: Due to the excellent insulating properties of SF6 gas, it is possible to design more miniaturized circuit breakers, which are suitable for places with limited space.

4. Long service life: SF6 gas does not react chemically with the metal parts of the circuit breaker, resulting in long equipment life and relatively low maintenance costs.

5. Good operational stability: the circuit breaker has a stable working condition under high voltage, which is suitable for frequent operation and harsh working environment.

6. International standards and safety approvals: Most SF6 circuit breakers comply with the standards of the International Electrotechnical Commission (IEC), ANSI and other standards  for  power  equipment,  and  have  obtained  a  number  of  international certifications. This ensures the safety, reliability and consistent performance output of the  equipment.  Using   SF6   circuit  breakers  means  you  are  choosing  a  globally recognized quality device.

SF6 circuit breaker working principle:

When the circuit breaker receives a control signal and needs to open the circuit, the contacts of the circuit breaker separate and the current generates an electric arc. At this time, the negative ions generated by the decomposition of SF6 gas can quickly absorb

the energy of the arc, thus making the arc extinguished and achieving the purpose of opening the circuit. When the circuit breaker is closed, the contacts close again to restore the normal operation of the circuit.

SF6 circuit breaker application scene:

SF6  circuit  breaker  is  widely  used  in  high-voltage  and  ultra-high-voltage  power transmission and distribution systems, such as substations, powerplants, industrial and mining enterprises. It is especially suitable for power systems with high requirements for reliability and environments with extreme climatic conditions, SF6 circuit breakers are used with high safety and stability.

Main applications of SF6 circuit breakers:

The main use of SF6 circuit breakers focuses on high-voltage and ultra-high-voltage power systems, which are widely used for power protection in power transmission and distribution   systems,   power   plants,   industrial   enterprises   and   various   critical infrastructures. Its main uses include the following aspects:

1. Protection and control of high-voltage transmission lines

SF6 circuit breakers are widely used for the protection and switching operation of high-voltage  transmission  lines.  In  high-voltage  transmission  systems,  where  the voltage level is usually  110kV  and above,  SF6  circuit breakers can reliably break circuits and prevent short-circuits, arcing and other electrical faults, thus ensuring the stable operation of the power system.

2. Circuit control in substation

SF6  circuit  breakers  are  one  of  the  most  commonly  used  switching  devices  in substations to manage the transmission and distribution of electricity. In substations, SF6 circuit breakers can effectively control and protect different busbars, power lines and equipments through reliable closing and breaking operations, ensuring fast power cut-off in case of faults and preventing the accident from expanding.

3. Generator protection in powerplants

In powerplants, SF6 circuit breakers are used for the protection of generators and their related equipment. In the process of power generation, any electrical fault may lead to equipment damage or even shutdown. SF6 circuit breakers protect generators and other equipment  from  faults  such  as  arcs,  short  circuits  and  overloads  through  fast  and effective fault isolation.

4. Electrical protection for industrial facilities and large buildings

Many industrial facilities, large commercial buildings and infrastructure projects (e.g. airports, railroads) require stable high-voltage power supply. SF6 circuit breakers serve as the core power protection equipment in these applications, ensuring that the point of failure can be isolated in time to ensure the safe operation of the system and reduce the outage time in the event of an abnormality in the power system.

5. Breaking and isolating load current

SF6 circuit breaker has good arc extinguishing performance and electrical insulation ability, and can safely disconnect and isolate the load current under normal working condition. It is suitable for frequent operation occasions, especially in the need for frequent closing and breaking operations in the power system (such as power load regulation, switching of distribution lines, etc.).

6. Suitable for high-voltage equipment protection in harsh environments

Compact  and durable,  SF6  circuit breaker  is able to work in a variety of extreme environments,  such  as  high  humidity,  high  pollution  and   severe  cold  areas.  Its applications include power systems in harsh conditions such as offshore wind farms, mines  and  oil  platforms,   ensuring   reliable  power  protection  even  in  complex environments.

7. Application in remote control and automated power grid

With the development of power systems in the direction of intelligence and automation, SF6 circuit breakers can be integrated with remote control systems and automation equipment to realize automatic closing and breaking operations and real-time fault detection. In smart grid and modernized power distribution system, SF6 circuit breaker becomes the key equipment for remote monitoring and power load management.
