Prefabricated chamber of unilateral service is designed for receiving, monitoring, and protecting the electrical system from the 6/10 kV side in distribution devices with frequent switching operations. Its design prevents conflicting operations from being performed simultaneously.
It is used in transformer substations, industrial electrical installations, central closed transformer substations for agricultural consumers, oil and gas companies, watercraft and railway transport.
The Prefabricated chamber of unilateral service application is recommended for busbar currents up to 1000 A or short-circuit currents up to 31.5 kA.
The Prefabricated chamber of unilateral service cells manufactured by EDS-POWER allow for the elimination of interruptions in power supply and the associated losses.
FEATURES OF THE TECHNICAL SOLUTION
- Regarding the purpose, the types of cells include: line cells (providing switching and protection of incoming and outgoing lines), transformer cells (connecting and protecting power transformers), sectional cells (managing the introduction of reserves), auxiliary cells (for installing transformers for internal use, etc.).
- Service is only performed from the front of the cell - up to 1000 A (very rarely up to 1600 A).
- No compartmentalization.
- Power switches are mostly of a stationary type.
- Cable entry from above or below, placement of busbars from above or below.
- Monolithic welded construction of enclosures with removable panels.
ADVANTAGES OF EDS-POWER MANUFACTURING Prefabricated chamber of unilateral service CHAMBERS
- Low cost.
- They provide practically all the necessary functionality (switching, protection, distribution) depending on the specific project requirements.
- The design ensures the protection of the operating personnel from electric shock, with a series of interlocks implemented for this purpose.
- There are inspection windows on the doors to monitor the status of disconnectors inside the camera.
- EDS equipment has successfully undergone testing for fault localization during emergency operation.
- The dimensions of the cell are significantly more compact than the standard Prefabricated chamber of unilateral service size, which significantly saves workspace inside the transformer substation/distribution point.
- Extremely high operational reliability.
