Application Research Of Arc Suppression Coil In Baoding Power Gria

To reduce single-phase fault of cables and overhead lines, and to eliminate over-voltage when grounding and such non-normal operations, arc-suppression coil is largely used in Baoding Grid. Application Research of Arc Suppression Coil in Baoding Power Grid is analyzed from the following aspects:(1) The grounding capacitance current measuring method is analyzed in this paper. Take Baoding Power Grid as an example, the pimples and application conditions of GW-2005with remote control and portable measuring device were given. Measured the grounding capacitance value and the grounding capacitance current of some Baoding substations were given.(2) But in actual operation, there have been massive arc-suppression coil defects. And the products from different manufacturers vary greatly, for this, in-depth study of way of distribution system grounding, arc-suppression coil selection is done in this paper. A detailed analysis of the arc-suppression coil grounding system, the range of applications, as well as its role, the arc suppression system tuning control; and the existing capacitor current detection method have been done. Detailed overview of the Baoding power grid operation, citing the current application of Petersen-coil type, manufacturer and other information are included.(3) Based on actual characteristics and circumstances of Baoding grid, improvement suggestions and comments are put forward.
