Abstract

The invention relates to an electric furnace load automatic detection recorder, comprising a voltage mutual inductor, a current mutual inductor, a first Rogowski coil, a second Rogowski coil, a first low voltage measuring sensor, a second low voltage measuring sensor, an integrator and a processor; wherein the voltage mutual inductor and the current mutual inductor are arranged at the primary side of an electric furnace transformer, the first Rogowski coil and the first low voltage measuring sensor are arranged at short web close to the electric furnace transformer, the second Rogowski coil and the second low voltage measuring sensor are arranged at the tail end of a water-cooling cable, the voltage mutual inductor and the current mutual inductor are connected with the processor, and the first Rogowski coil, the second Rogowski coil, the first low voltage measuring sensor and the second low voltage measuring sensor are connected with the processor by virtue of the integrator. Heavy current at low voltage side is accurately measured by Rogowski coil, thus providing guarantee for recorder to realize accurate monitoring.

Description

technical field [0001] The invention relates to an automatic load detection recorder for a submerged arc furnace. Background technique [0002] The submerged arc furnace system in the prior art usually includes an electric furnace transformer 1, a short network 3, a water-cooled cable 4 and an electrode 2 (see attached figure 1 ). Due to the large current of the submerged arc furnace, there is currently no special instrument for detecting the electricity consumption data of the electrodes in the furnace body. And the current and voltage control of the electrode is to use the current and voltage of the high voltage side (primary side) of the electric furnace transformer as reference data, and cooperate with experienced operation methods. The process requirements for various smelted products cannot be precisely and quantitatively controlled, so the quality of the products and the best output cannot be ensured. Contents of the invention [0003] In order to overcome the de...
