Abstract

The invention, which belongs to the technical field of metallurgical equipment, discloses an automatic switching control system for an alloy electric vibration fault behind a converter. The system comprises a WINCC, a PLC, a frequency converter, a first motor, a second motor, a first circuit breaker and a second circuit breaker. The WINCC is connected with the frequency converter through the PLC;a control panel of the frequency converter is connected with an auxiliary contact of the first circuit breaker and the second circuit breaker; a power supply terminal of the frequency converter is connected with a main contact of the first circuit breaker and the second circuit breaker; the first circuit breaker is connected with the first motor, and the second circuit breaker is connected with the second motor. A fault parameter scheme and a normal parameter scheme are set in the frequency converter; and when the frequency converter detects that the level signal of the auxiliary contact of the first circuit breaker or the second circuit breaker changes, the working parameters of the frequency converter are switched from the normal parameter scheme to the fault switching scheme. The frequency converter automatically judges whether a fault occurs during operation or not, and then controls to make a decision that whether to operate after automatic reset or to be in a standby state. According to the system provided by the invention, high-timeliness fault switching can be realized, and stable operation of electric vibration is maintained.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an automatic switching control system for alloy electric vibration failure after a converter furnace. Background technique [0002] Alloy electro-vibration after the steel-making converter is the key equipment for feeding the steel-making converter. One frequency converter uniformly controls the synchronous operation of two electro-vibration motors. However, when one of the motors fails, the operator needs to go to the site to manually change the inverter parameters to drive the remaining electric vibration motor to run, so as to ensure the stable performance of the alloy electric vibration. This also leads to poor timeliness for troubleshooting, which affects the feeding time and steelmaking time, and restricts the smooth production. Contents of the invention [0003] The invention provides an automatic switching control system for alloy electro-vibration faul...
