Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] The invention provides a 3kV-66kV power distribution system adaptive neutral point grounding device, such as figure 1 As shown, it includes a fast switch 3, and a first resistor 1 and a second resistor 2 connected in series, the other end of the first resistor 1 is connected to the neutral point of the system, the other end of the second resistor 2 is grounded, and the fast The switch 3 is connected in parallel with the first resistor 1; the resistance of the first resistor 1 is greater than the resistance of the second resistor 2; the action voltage of the fast switch 3 is greater than the relative ground voltage.
[0029] The first resistor 1 is a linear or non-linear resistor of several thousand ohms to tens of mega-ohms, preferably a non-linear resistor, such as a metal oxide varistor or a silicon carbide varistor (usually packaged in a porce...
