MVTT14B1BA0773C | GEC ALSTHOM Relay Module

Whether in voltage disappears completely, or within the grid short-circuit fault | up when brake motor, the connection mode of low voltage protection, should be able to guarantee the motor disconnect.  For this, low voltage protection Wiring should meet the following requirements: 1.  Can reflect symmetric and asymmetric voltage drop.  Since the motor may also be braking in the asymmetric short circuit, the self-starting problem will also occur when the voltage is restored. 2.  When the one-phase or two-phase line is broken on the first-secondary side of the voltage transformer, and each phase line is broken on the secondary side (such as fusing), the protection device should not misoperate and send a signal.  But during the secondary circuit break failure, if At this time, the factory bus really loses voltage (or voltage drops to the specified value), the low voltage protection should still operate correctly. 3.  When the isolation switch or isolation contact on the primary side of the voltage transformer is disconnected due to misoperation, the protection device should not misoperate and should send a signal. 4.The operating voltages of 0.5 and 9s low voltage protection shall be set separately.  When the voltage is lost, the protection of a voltage relay connected to the in-line voltage can be achieved and can reliably respond to the three phases Short circuit.  However, when the two-phase short-circuit occurs, the protection formed by a voltage relay only works when the short-circuit occurs between the two phases of the relay, so the asymmetric voltage drop cannot be fully reflected.  for To ensure that protection can operate in all cases of two-phase short circuit, three-phase relay wiring can be used.  Several motors in the same section, powered by a busbar, usually have a common low voltage protection Let's put.  The voltage relay is connected to the transformer of the plant busbar.
