High-voltage SF6 circuit breaker
Voltage range
110-330 kV
Frequency
50 Hz
Main characteristics:
- Circuit breaker is used as equipment for monitoring and protecting power systems, and can also be used as a switch for connecting individual power systems
- Circuit breaker is a structure based on three porcelain poles-phases for outdoor installation, installed on a frame with racks
- A spring-motor drive is installed in the circuit breaker cabinet
- The poles of the circuit breaker are filled with SF6 gas, a device for monitoring the density of the SF6 gas is installed in the switch frame
Outdoor disconnectors
Voltage range
110-330 kV
Main characteristics:
- Outdoor disconnectors 110-330 kV are used for switching de-energized sections of the electrical grid with a voltage class of up to 330 kV
- The design consists of individual poles, which, depending on the requirements, can be used in single-pole, double-pole or triple-pole installation options
- The design of the disconnector pole is made in the form of a two-column device with contact rotating in a horizontal plane and consists of a base, insulation columns, a conductive part and a grounding device
- The grounding device of the disconnector is a earthning switch (or two), permanently installed on the disconnector base and a fixed contact installed on the main contact
- The main parts of the disconnector are made of ferrous metals, treated with an anti-corrosion coating in the form of hot zinc
