How to handle how to handle when using the resistance cabinet? The resistance cabinet of the generator is a good combination of grounding equipment, which also includes a ground transformer. Its equipment has been constantly developing well and has a wide range of applications. Typically, it can be installed in power generation. In the power system, the power supply system of the substation, the power supply system of the industrial and mining enterprise, the system operating mode of the generator resistance cabinet is implemented in these grids. In accordance with it, the neutral point resistor is more suitable for the case where the neutral point of the system is in small resistance or the medium resistance. It has certain specific properties. When you fail during use, you need to trip it to remove the fault line.
The resistor cabinet inside the ground transformer is a very good grounding device. Its equipment is well developed from time to time and has a wide range of applications. Typically, it can be installed in power systems in power plants. Relatively has certain specific properties. When a resistance is flex, you need to trip now to remove the fault line.
The resistor cabinet is relatively applicable to the system where the system is low resistive or the medium resistance. It has certain specific properties. It is necessary to trip now to remove the fault line. By the ground and the resistance cabinet, the resistance is limited to the appropriate value, and the sensitivity of the relay protection can be improved to deal with the trip. At the same time, only a small amount of local burn occurs at the point of failure, limit the transient overvoltage to 2.6 times the normal line voltage to the voltage, limit the re-ignition of the arc, prevent the main device of the arc gap over voltage damage, and effectively Prevent iron frequency converters. Overpower to ensure that generators in the resistor can operate safely.
