How big is the insulation resistance requirement of the induction melting furnace to work properly?

(1) The resistance of the input loop of the rectifier of the induction melting furnace is not less than 10kQ to the ground after the water is passed through.

(2) Induction melting furnace rectifier thyristor (KP) tube circuit is greater than 100kfto

(3) The input loop resistance of the inverter of the induction melting furnace is not less than 2kQ to the ground after water is passed through.

(4) Induction melting furnace inverter thyristor (KK) tube resistance is greater than 10mo

(5) Induction melting furnace inverter output resistance is greater than 5kQ.

(6) The insulation of the induction coil of the induction melting furnace is not less than 100kQ without water, and the insulation to the ground after water is not less than 5kQ.
