Anti-seismic I-type industrial case suitable for power station/power plant instrument control system

Abstract

The invention relates to an industrial case, belongs to the technical field of industrial instrument control equipment cases, and aims to improve the anti-seismic capacity, electromagnetic interference resistance and ventilation cooling of the industrial case. The industrial case is characterized in that the upper, lower, left and right outer side surfaces of the case are welded into a whole in a seamless manner by a metal plate; an upper fan bracket and a lower fan bracket in the case are fixedly connected with the case through stud bolts respectively; card guide rails are connected side by side into a whole to form a card guide rail component between the upper fan bracket and the lower fan bracket; metal shielding bars are arranged in mounting clearances among front and back panels of the fan brackets and card panels; a through hole position on a guide plate arranged between the lower fan bracket and the card guide rail component corresponds to a clearance between cards on the card guide rail component. The outer side surfaces of the case are welded into a whole in the seamless manner through the metal plate, so that the internal structure is compact and firm, the anti-seismic performance is good, and internal components can be prevented from being influenced by extreme temperature conditions, continuous vibration environment and unexpected shock environment.

Description

technical field [0001] The invention belongs to the technical field of industrial control equipment, and in particular relates to a cabinet suitable for installation and protection of electric equipment with high safety and reliability requirements such as power station or power plant instrument control system. Background technique [0002] For a complete control system platform, the chassis plays an important role in ensuring the normal operation of the system. First, the chassis provides a suitable location for each component inside, thereby protecting the internal components from a variety of external environments and conditions, including various extreme temperature conditions, continuous vibration environments, and accidental shock environments. In addition, the chassis is also an integral part of the system EMC design. Because industrial chassis are often used in harsh environments and will encounter more complex environmental factors, compared with general commercial...
