|
EDPM-220 type microprocessor-based motor differential protection device is suitable for 3kV ~ 10kV voltage asynchronous, synchronous motor. Used the ratio restraint principle, can be provied sensitive protection for various systems in a variety of large, medium capacity ( power over2000KW ) motor winding and lead-out wire of interphase short circuit fault. And EDPM-210 type microcomputer motor protection and monitoring device matching, improve the composition of the large, medium-sized motor protection and control.
Protection Function 1、Differential instantaneous protection 2、Ratio differential protection 3、Magnetic balance differential protection 4、Discrimination of CT breakingOrdering instructions Provide the following upon ordering: 1. Name, model and quantity of the device. Please specify any special requirement differs from our standard product. 2. Voltage class. The operating power supply for any device is intended for both AC and DC purposes, with 110V and 220V inputs; the 220V version will be provided unless otherwise specified. 3. Communication port: The device standard communication configure is a single 485. If needs dual RS485 network which shall be specified. 4. Ratings of key parameters For a protector, provide the nominal rated current (1Aor5A) For a device with the zero sequence current protection function in a low-current ground system, provide the rated zero sequence current (0.2Aor0.02A) 5. Term and place of delivery, means of transport 6. Other terms shall be negotiated. |
