AGS Gas-Insulated Switchgear

GIS circuit breakers are typically operated by hydraulic, pneumatic, or spring‑actuated mechanisms, while disconnect switches and earthing switches are generally driven by pneumatic, manual, electric, or electric‑spring actuators. In transmission lines, GIS serves both control and protection functions, making it one of the most critical pieces of power transmission and distribution equipment. With advantages such as compact size, minimal footprint, ease of installation and construction, immunity to external environmental conditions, safe and reliable operation, flexible configuration, simple maintenance, and long overhaul intervals, GIS has gradually replaced air‑insulated and oil‑less alternatives. It is now widely deployed in power grids at 72.5 kV and above, particularly gaining widespread adoption in hydropower substations and urban distribution substations. Moreover, GIS has become the preferred choice for ultra‑high‑voltage transmission and transformation equipment. As urban development expands in scale and pace, and in response to the needs of railway infrastructure, GIS is also finding practical applications in the medium‑voltage sector.

DSC High-Voltage Disconnect Switch

Reliable contact structure: spring‑pressed sliding contacts ensure self‑cleaning and self‑locking during closing, withstanding a 31.5 kA/3 s short‑circuit current; low and stable loop contact resistance. Double‑column, centrally interrupted, hot‑dip galvanized steel base; insulators are adjustable for leveling; standard 90° opening and closing stroke; excellent mechanical stability. Safety interlock: integrated hard‑mechanical interlock with the earthing switch, completely preventing erroneous live‑earth connections; available in male/female contact configurations for earthing. Universal mounting: compatible with rectangular and circular reinforced‑concrete poles; vertical drive shaft can be segmented to suit different installation heights; supports both electric and manual operating mechanisms. Easy maintenance: standardized disassembly and assembly procedures, accompanied by a comprehensive lubrication plan; three‑level periodic maintenance schedule; contacts and transmission components can be replaced individually. Complete protection: factory‑applied protective coating on conductive surfaces; optional anti‑condensation heating for the mechanism; all components resistant to outdoor weathering and corrosion.

AGL circuit breaker

The AGL‑126 outdoor high‑voltage AC sulfur hexafluoride circuit breaker (hereinafter referred to as the “circuit breaker”) is an outdoor‑mounted, three‑pole, 50 Hz AC high‑voltage switchgear that uses SF₆ gas as both the arc‑extinguishing and insulating medium. It can be used to make and break rated currents and fault currents, switch capacitor banks, and transfer circuits; it may also serve as a tie‑breaker, providing control and protection for transmission and distribution lines and associated equipment. It is particularly well suited for frequent operations and is equipped with a CT20 spring‑operated mechanism.

Solution of SF6 densimeter without disassembly and calibration (SF6 three-way valve)

Requirements for SF6 densitometer in the operation regulations of the State Grid, DL/T596-1996 Preventive Test Procedures for Electric Power Equipment implemented by the Ministry of Electric Power on January 1, 1997: "SF6 gas densitometer (including setting value) inspection" is included in the No. 13 of the "switchgear" section. The test time required in the regulations is 1-3 years, after major repair or when necessary, the specific calibration time is formulated by the pilot plants in each province, and it is generally appropriate to calibrate at least once every 3 years, It is applicable to high voltage circuit breakers and combined circuit breaker GIS of ABB, Siemens, Schneider, Areva and other brands. 1.

Manufacturing and debugging process of electric control system

3. Making the control cabinet and on-site construction 1) When making the control cabinet, the engineer shall first draw the power incoming wiring diagram of the PLC and the power supply wiring diagram of the output actuator; 2) Draw the layout of components in the electrical cabinet and the mutual wiring diagram; Draw the layout of control panel components. 3) If the power supply of PLC has interference, filter and isolation transformer shall be set. In addition, the engineer shall separate the signal line, power line and power line and use trunking or metal pipe for wiring. 4) Special attention shall be paid to the safe, correct, reliable, reasonable and beautiful installation, and the grounding of PLC shall be properly handled, and the anti-interference ability of the system shall be improved
