Zi Kai Box type fixed AC gis gas insulated switchgear Cabinet type
Bus connecting cabinet
The busbar connection cabinet is used to connect the cable to the busbar. The cabinet is equipped with a cable clamp for fixing the cable. Also can choose the current transformer, lightning arrester and other components. Cabinet width 375mm or 500mm.
Bus section cabinet
The bus section cabinet is always used with the bus lift cabinet, the basic cabinet is 375mm wide and equipped with a FLN36-12 or FLN48-12 or SFG type three-station SF6 load switch for the bus section.
Bus lifting cabinet
The busbar lifting cabinet connects the busbar to the bottom of the section cabinet with the load switch. When the cabinet is 500mm wide, it can be used as a measuring cabinet.
Measuring tank
The measuring cabinet is used to measure voltage, current and power. The front door and the lower door are equipped with special lead seal, which is convenient for the lead seal of the power supply department.
Dual power input cabinet
The equipment is composed of two load switch counters with electric power and a full set of standby automatic switching devices. In order to realize the automatic switching function of the system, the system not only has the traditional PT acquisition voltage in the voltage judgment, but also introduces the live display verification mode, and according to the actual situation, the equipment can be set as the following two working modes:
* The incoming line is one master and one backup
* The two lines are alternate to each other
Zi Kai Box type fixed AC gis gas insulated switchgear Feature
Footprint optimization: GIS equipment significantly reduces the space required due to its fully enclosed design, making it ideal for space-constrained environments.
Excellent reliability: By sealing all live components in the SF6 gas environment, GIS equipment is effectively insulated from external adverse factors, which significantly improves the operational stability and durability of the equipment.
Maintenance simplicity: The fully enclosed structure of GIS not only simplifies the maintenance process, but also reduces the necessary maintenance frequency, which reduces the maintenance cost of the equipment, while extending the interval period between two overhauls.
Low electromagnetic radiation: The metal shell of the GIS constitutes a solid barrier, effectively blocking the leakage of electromagnetic radiation, ensuring the stable operation of the device itself, and protecting the surrounding environment from electromagnetic interference.
