Power distribution cabinet 1, its main principle is the use of bottom-proof measure dielectric isolation ignition source so as to achieve the purpose of proof; 2, this product can be installed according to user requirements of various common monitoring instruments, analytical instruments, display instruments, Monitor Microcomputer touch screen, power inverter and general electrical components, electrical components built on the basic user unrestricted; 3, which is mainly composed of the cabinet, automation systems, gas distribution systems, alarm systems, power distribution system components; cabinet from positive pressure chamber and the secondary chamber composition, vice intracavitary automation systems, alarm systems, and user access to cable; positive pressure chamber installed user distribution system components; power distribution cabinet 4, the pressure explosion-proof electrical cabinet according to user requirements were customized into a box, piano desktop and cabinet structure, divided into upper and lower cabinet structure and around the structure. Box generally use welded steel, powder coated, front door operation; Qin its desktop and cabinet cabinet using standard profiles welded joints have been for each of its special sealed; front door after door repair operation. Steel materials generally used GB710-88 cold-rolled steel, can also be used GB3280-84 stainless steel according to user requirements; 5, according to the air intake divided into ventilated and compensated. Vented gas supply for the continuous operation, positive working heat chamber loaded with gas path components can be taken away, with good heat dissipation; compensating for the intermittent supply, the positive pressure chamber has a good seal, the small air consumption ; power distribution cabinet 6, the user must provide the gas source, the requirements are: clean air or nitrogen gas source pressure: 0.2MPa-0.8MPa; usually wind instrument user site can meet the requirements. According to user requirements, our company supply system from its design. Power Distribution Cabinet
