Electric control chamber arrangement structure under copper alloy casting furnace platform

Abstract

The invention relates to an electric control chamber arrangement structure, in particular to an electric control chamber arrangement structure under a copper alloy casting furnace platform. The electric control chamber arrangement structure comprises a transformer chamber and a power supply control chamber which are adjacently formed in the front and rear portions of the lower portion of the equipment furnace platform; the transformer chamber is formed in the rear portion of the lower portion of the equipment furnace platform; a smelting furnace transformer and a heat-preservation furnace transformer are arranged in the transformer chamber; a smelting furnace power supply control cabinet and a heat-preservation furnace power supply control cabinet are placed in the power supply control chamber; a ventilation pipeline is mounted on an upper top plate of the power supply control chamber; a communicating underground air channel is formed in the underground of the power supply control chamber and the underground of the exterior of the power supply control chamber; an air supply fan outside the power supply control chamber is connected with the outer end of the underground air channel;an underground air channel outlet is formed in the position, close to a wall, of the power supply control chamber; the other end of the underground air channel communicates with the lower end of the underground air channel outlet; and the upper end of the underground air channel outlet communicates with one end of the ventilation pipeline. Safe and reliable operation of a transformer and power supply control equipment is effectively ensured.

[0002] It is known that the copper alloy melting and casting production line is mostly arranged in the middle of the workshop, consisting of a melting furnace, a holding furnace, and a casting machine. The main power load is concentrated on the high-power electric heating equipment supporting the melting furnace and holding furnace; Rectification devices, including rectification transformers, power supply cabinets, rectification cabinets, compensation cabinets, control cabinets and other electrical equipment; according to the technical requirements of equipment and the manufacturing capacity of transformers, comprehensively considering factors such as equipment costs, the current rectification or voltage regulation of high-power induction heating furnaces Most of the transformers are oil-immersed transformers. In the past, the conventional design is to arrange the rectifier or voltage regulating transformer of the melting furnace and holding furnace in the workshop, and the power control equipment of the furnace is arranged in the control room under the furnace table. The distance between the transformer and the power control equipment is relatively small. The line loss and long-term operation loss are relatively large; the oil-immersed transformer is arranged in the workshop close to the melting furnace and the holding furnace, which can solve the problem of line loss, but there are big problems in the ventilation and fire prevention of the transformer. Mineral oil plays the role of insulation and cooling. The transformer room belongs to Class C fire hazard environment, and the transformer and power supply control cabinet are also heating equipment. Therefore, a method is proposed to ensure the normal ventilation of the transformer room and the electric control room in the workshop environment, and meet the The layout structure of the electric control room under the copper alloy melting and casting furnace platform according to the fire protection design specification has become the basic appeal of technicians in the field
