Embodiment 1
[0053] see Figure 1-Figure 10 As shown, this embodiment provides a method for researching and controlling the heating of the cable grounding wire adjacent to the three-phase reactor, including the following steps:
[0054] S1. Establish the electromagnetic field model of the reactor and the cable armor layer and use the equivalent resistance to equivalently form a closed loop between the grounding resistance at both ends of the armor layer and the ground, and load the reactor according to the actual operating power frequency current provided by the substation to conduct electromagnetic field The finite element numerical calculation is used to obtain the distribution of magnetic force lines in the space around the three-phase reactor and the current value of the grounding wire of the armor layer;
[0055] Among them, the establishment of the reactor and the electromagnetic field model of the cable armor layer is an overall three-dimensional model. First, when the reactor model...
