Oil circulation air-cooling control system of transformer of submerged arc furnace

Abstract

The invention discloses an oil circulation air-cooling control system of a transformer of a submerged arc furnace. The oil circulation air-cooling control system of the transformer of the submerged arc furnace comprises an air cooling system, a control device, a temperature sensor, an actuating module, an LCD (liquid crystal display) and an operating module, wherein the air-cooling system comprises a circulating oil system and an air cooler and is connected with the actuating module; the control device comprises a programmable logic controller (PLC), a wireless communication module and a remote controller; the remote controller is wirelessly communicated with the programmable logic controller (PLC) remotely through the wireless communication module; the temperature sensor detects the temperature of oil on the top of an oil tank of the transformer in real time, and transmits acquired oil temperature signals to the programmable logic controller (PLC); and the LCD and the operating module are connected with the programmable logic controller (PLC). The air-cooling control system has a remote control function, an intelligent monitoring function and a manual monitoring function, and can accurately and efficiently control an air-cooling system of the transformer in real time from multiple functions; and long-term normal running of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of transformers, and relates to an oil circulation air cooling control system for submerged arc furnace transformers. Background technique [0002] Submerged arc furnace, also known as electric arc furnace or resistance electric furnace, is mainly used for reducing and smelting ore. It is an industrial electric furnace with huge power consumption. The submerged arc furnace is in the working state of continuous operation for a long time during the smelting operation. In its working state, the normal and stable working voltage must be ensured to ensure the normal operation of the submerged arc furnace and improve its working efficiency. The submerged arc furnace transformer is the most critical large-scale supporting equipment for the submerged arc furnace. Especially during the melting period of smelting ore, the voltage transformer needs to maintain the highest electric power and be in a high-intensity conti...
