10kVRated current:
630A, 1250A, 1600A, 2000A, 2500A, 3150A, 4000ACasing:
Usually, IP4X is required (to prevent solid objects with a diameter greater than 1mm from entering), and IP2X is required inside after the door is opened (to prevent fingers from touching live parts).Reliable grounding:
All metal casings, partitions, doors, etc., are reliably grounded.Observation window:
Used to observe the status of internal components.Core parameters
System and rated voltage
The system voltage is 12kV, and the rated working voltage is 10kV.
These are the basic voltage parameters for the switchgear to
operate in the power system, which determine its applicable voltage
level range, ensure matching with the 10kV transformer, and ensure
the stability and safety of power transmission.
Rated current range
The rated current has multiple specifications from 630A to 4000A to
meet the needs of transformers of different capacities and loads.
The current carrying capacity is a key indicator to measure whether
the switchgear can stably transmit electric energy. When the
current is too large, a switchgear with a suitable current level
must be selected to avoid overload.
Rated frequency
The rated frequency is 50Hz/60Hz, which adapts to the power grid
frequency in different regions. The stability of the frequency is
crucial to the normal operation of the transformer and switchgear.
Frequency deviation may cause abnormal operation of the equipment,
affecting the stability of the power system and the life of the
equipment.
Core features and advantages
Advantages of the removable structure
The removable structure facilitates the installation, maintenance,
and replacement of equipment and improves the flexibility and
maintainability of the switch cabinet. When the internal components
of the switch cabinet need to be repaired or replaced, the
components can be quickly removed to reduce power outage time and
improve power supply reliability.
Flexible operation and maintenance
The design of the switch cabinet focuses on the convenience and
flexibility of operation. Operators can easily perform opening and
closing operations, parameter settings, etc. At the same time, it
is equipped with a complete indication and alarm system to
facilitate real-time monitoring of the equipment operation status
and timely detection and handling of abnormal situations.
Importance of the live-protection interlocking
The five-protection interlocking is an important safety feature of
the switch cabinet. It prevents safety accidents caused by
misoperation, such as preventing the opening and closing of
disconnecting switches with load, preventing accidental entry into
live intervals, etc. Through mechanical and electrical interlocking
devices, it ensures the correctness and safety of operation and
ensures the stable operation of the power system.
