Arc suppression coil and grounding transformer cabinet
Arc suppression coil and grounding transformer cabinet
The role of the arc suppression coil is to provide an inductive current to compensate the grounding capacitor current after a single-phase grounding fault occurs in the power grid, so that the grounding current is reduced, and the speed of the recovery voltage at both ends of the faulting grounding arc is reduced to achieve the purpose of extinguishing the arc. . When the arc suppression coil is properly tuned, it can not only effectively reduce the probability of generating arcing ground overvoltage, but also effectively suppress the overvoltage amplitude, and also minimize the thermal damage of the fault point and the voltage of the ground network. Wait. The so-called correct tuning, that is, the inductor current is grounded or equal to the capacitor current, and the degree of tuning is described by the degree of detuning V in engineering. After the capacitor current flows into the ground, stray current is formed in the ground. This current may generate sparks, ignite gas explosions, etc., may cause the detonator to fire in advance, and corrode water pipes and gas pipes.
