detailed introduce：LMZB-0.5A.B current transformer
- Project description：
LMZB-0.5A.B current transformer
The current transformer is casting resin insulated and used indoors.It is used for over -load protection of distribution transformer. The type of the relay fitting with the transformers is MPRB99 -1.00 - GF.The transformers can be executed according to the standards IEC.
二、 Type designation
The transformers are busbar type.When the single-phase cable goes through the hole,the relevant econdary current can be found in the outline of the secondary windinS;The transformer has two secondary windings. One of them is used for protection, the outline singe is SO,Sl (tap) and S2; another is used testing, the outline singe is C and D.
四、 Technical data
1.the highest working voltage:0.72kV；
2.power frequency voltage withstand level:3kV;If the SO and C are being connected with the earthen terminal EARTH inside of the transformer, this test is not requested.
3.The primary current change range and secondary current see form：
