Характеристики





1、The neutral point of the power system (mainly refers to the neutral point of the generator and transformer) operates in three ways: the neutral point is not grounded, the neutral point is grounded through the arc suppressing coil or resistance, and the neutral point is directly connected.

2、The operation mode of the neutral point of the power system is different, and its technical characteristics and working conditions are also different, so the influence and requirements on the reliability of operation, equipment insulation and its protection measures are also different.

3、The neutral point can be grounded through a resistor to limit the fault current to an appropriate value. On the one hand, the relay protection has sufficient sensitivity and selectivity, and at the same time, only local slight damage may occur at the fault point, and the transient overvoltage is limited. To 2.6 times of the normal line voltage to the neutral point voltage, limit the reignition of the arc, prevent the arc gap overvoltage from damaging the main equipment, and also have a significant effect on preventing ferromagnetic resonance overvoltage.3. DZ series neutral point grounding resistance cabinets mainly include generator neutral point grounding resistance cabinets, transformer neutral point grounding resistance cabinets, low-voltage neutral point grounding resistance cabinets, etc., and can be customized according to user needs.





technical indicators
1. The product can increase the grounding record function. Record the number of times the grounding resistance is grounded.
2. An isolating switch can be added for easy maintenance.
3. Rated voltage, current, transformer ratio of transformer or generator.
4. The way of entering and exiting the cabinet.
5. Resistor material, resistance value, flow current and flow time.
6. The capacity and transformation ratio of the transformer.
7. The material of the cabinet, the color of the spraying, and the degree of protection; whether the resistance is tapped.
8. Is the resistance cabinet installed with a grounding counting device.
9. If there are other requirements, please explain them when ordering.

Note: 1. The resistance value of the resistance cabinet can be from 1 ohm to 2000 ohm, and the current can be designed from 1 ampere to 2000 ampere. The allowable flow time is 10s, 15s, 30s, 60s, 2h. The error of resistance value is ±3%.
2. The resistance cabinet is used outdoors or outdoors. The cabinet body is supported by stainless steel plate or cold-rolled steel plate sprayed with plastic, with high corrosion resistance and high protection level.
3. An isolating switch can be added, which is convenient for maintenance, and a temperature and humidity control device can also be added.
4. An intelligent monitoring device can be installed, which can monitor the unbalanced current of the neutral point, the resistor sheet, and the temperature in the resistor cabinet under normal operation of the resistor cabinet, and can also monitor the current at the moment of a single-phase ground fault and record the number of grounding operations. And a communication interface is reserved, which can transmit the detected and recorded information to the main control room, so that the operating personnel can get the information in the first time.
