Outdoor explosion-proof vertical electrical control cabinet with built-in heat dissipation protection structure
Technical Field
The invention relates to the technical field of electric power, in particular to an outdoor explosion-proof vertical electrical control cabinet with a built-in heat dissipation protection structure.
Background
The electrical control cabinet is formed by assembling switch equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements, and the arrangement of the electrical control cabinet meets the requirement of normal operation of an electric power system, is convenient to overhaul and does not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be switched on or off by means of a manual or automatic switch. When the fault or abnormal operation occurs, the circuit is cut off or an alarm is given by the aid of the protective electric appliance. The measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or send out signals for deviation from normal working state. The explosion-proof agent is commonly used in various distribution, distribution and transformation substations, and has three requirements for preventing explosion: ignition point; combustion supporting gas (special substances can be combusted and exploded under non-O condition, for example, Mg can be violently combusted in carbon dioxide); combustibles are considered, one of the requirements is limited, and the generation of explosion is limited. Selecting corresponding explosion-proof instrument and explosion-proof electrical equipment, wherein the standard structure comprises: explosion-proof type, increase ampere type, positive pressure type, fill husky type, intrinsically safe type and oil charge type, corresponding explosion-proof instrument and explosion-proof electrical equipment are generally selected to the blast-proof measure, and the standard structure has: the explosion-proof type, safety-increasing type, positive pressure type, sand-filled type, intrinsic safety type, oil-filled type and the like, select an adaptive ventilation method, prevent or reduce the possibility of combustible substance leakage to the maximum extent, do not use or use as little as possible electric elements which are easy to generate electric sparks, and adopt a nitrogen-filled method and the like to maintain an inert state. Some electrical control cabinets can install the open air at present, and the open air environment is more abominable for electrical control cabinet's heat dispersion is relatively poor, often can receive debris impact moreover, and dust and stone etc. cause the influence to the switch board, and electrical components itself has certain danger in the use, can produce the spark because of various reasons and explode even, cause serious harm.
Therefore, we propose an outdoor explosion-proof vertical electrical control cabinet with a built-in heat dissipation protection structure, so as to solve the problems mentioned above.
