[0034] 1) Selection of current induction transformer 1:
[0035] When the load current is large, it can be carried out by connecting multiple units in parallel. In the scheme, a series current induction transformer is temporarily used as an example for calculation. In the implementation of this device system, the key technology lies in the determination of the capacity of the current induction transformer 1, and the diameter of the transformer core cross-section is selected according to the transformer design principle formula Among them, S is the rated capacity kVA of the transformer, K is the coefficient, take 50~55, and the power value of the estimated harmonic in this scheme is 25% of the entire load, that is, the apparent power S, therefore, take 600÷3=200A , when the shunted load is 200A, intercept 20% of the voltage in the load as the basis, ⊿U 1 =0.2×380V=76V, so the power capacity value of the converter transformer BL-(1) is selected as:
[0036] S 1 =⊿U 1 ·I = 7...
