Embodiment Construction
[0044] Such as figure 1 , figure 2 with image 3 A flow battery-based AC ice-melting method shown includes the following steps:
[0045] S1: Connect the end of the power transmission line to be thawed with the grounding system 4 including the resistor 41 and the sixth switch unit 42; one end of the resistor 41 is grounded, and the other end is connected to the end of the power transmission line to be thawed through the sixth switch unit 42 connected, execute S2;
[0046] S2: The main control system 5 according to the formula I C =(D / ρ)[(t s -t)(πh+πσεt 3 +2EVWc w +2EVW E L V ]Calculate the critical current I to prevent icing on the transmission line that needs to be melted C , where D is the wire diameter of the transmission line to be ice-melted, ρ is the resistivity of the wire of the power transmission line to be ice-melted, and t s is the surface temperature of the conductor of the transmission line that needs to be iced, h is the convective heat transfer coeffi...
