结尾
综上，MMLG01B1AA0001C 是 MMLG01 标准款的一个具体物料版本，需手动短接 CT、13/14 端子不可接 CT、且不适用于母线保护场景。
MMLG01B1AA0001C is a specific material version of the ALSTOM Midos series MMLG01 standard test block, which belongs to passive electromechanical isolation accessories.
Product features (5 items)
B1AA0001C is a material variant code representing a specific hardware revision status and production batch.
For conventional lines and transformer protection cabinets, MMLG02 dedicated version is required for busbar protection.
The CT circuit does not have automatic short circuiting, and the operator needs to manually install the short circuiting link in advance.
Terminals 13/14 are dedicated for tripping or isolating auxiliary power circuits, and are strictly prohibited from being connected to CT circuits.
Relying on internal mechanical contacts to achieve circuit isolation and connection, without the need for auxiliary power supply.
Product application areas (10 items)
Secondary injection test of conventional line protection cabinet
Regular calibration of transformer protection screen
Isolation of generator protection circuit in power plant
Distribution substation feeder protection test
Maintenance and upkeep of industrial user substations
Replacement of old Midos protective screen spare parts
Protection relay transformation transition interface
Test scenarios that require manual short circuiting of CT
Trip circuit safety isolation
Expansion of testing interface for relay protection panel cabinet
ending
In summary, MMLG01B1AA0001C is a specific material version of the MMLG01 standard model, which requires manual short circuiting of CT, 13/14 terminals cannot be connected to CT, and is not suitable for busbar protection scenarios.
