Abstract
The utility model discloses a depressing control cabinet for a cold-heat dual-purpose rolling mill, comprising a cabinet body, wherein two alternating current vector type frequency converters are arranged in the cabinet body and are connected with two-roller depressing alternating current variable frequency motors; and the cabinet body is provided with an incoming line reactor, an isolation switch and a contactor. The depressing control cabinet for the cold-heat dual-purpose rolling mill has simple structure; and the two-roller depressing alternating current variable frequency motors are controlled by two 45KW alternating current vector type frequency converters and the depressing speed can be adjusted. The incoming line reactor is used for reducing the harmonic waves, surge and peak point current of a main power supply, improving the low-frequency conduction anti-interference performance, protecting power electronic elements of a driving mechanism, improving power factors and preventing the tripping caused by voltage spike pulse of the main power supply. When in overhaul, the power supply is disconnected by using the isolation switch and is connected after the overhaul is finished so as to ensure the safety in work. The contactor is used for frequently switching on or off an alternating current circuit and a direct current circuit and has the characteristics of high control capacity and remote operation.
Description
Technical field
The utility model belongs to the milling equipment technical field, is specifically related to the control cubicle of depressing that a kind of cold, hot two-purpose milling train uses.
Background technology
