Ring Main Unit (RMU) Switchgear and Box Type Transformer Substation
Overview It is used for motor centralized control and capacitance compensation of power and distribution in power generation and supply system of three-phase AC 50Hz, rated working voltage 400V (690V), rated current 4000A or less. It is applicable to power plants, petroleum industry, chemical industry, metallurgical industry, textile industry and high-rise buildings and other occasions, as well as high automation occasions that require connection with computers such as large power plants and petrochemical systems. The product has passed the national compulsory product certification (CCC certification), in compliance with the GB7251.1 and JB/T9661 standards, and it passes a long test run assessment.
TECHNICAL CHARACTERISTICS The frame adopts 8NF open-type steel, the main frame is equipped with Φ9.2mm of mounting holes of which the number of molds is E= 20mm and E = 100mm, and the frame is assembled flexibly and conveniently Each function room of the switch cabinet is isolated from each other, and the compartments are divided into function unit, busbar room, and cable room. The role of each room is relatively independent The horizontal bus is arranged in a flat arrangement after the cabinet to enhance the ability of the bus of resisting electric power, enabling the main circuit to have basic measures of high short-circuit strength. The design of the cable compartment makes it convenient for the cable going in and out The height of the drawer is 160mm. The drawer changes only in height, and its width and depth remain unchanged. The drawer of the same function unit has good interchangeability. The rated current of the unit circuit is under 400A The drawer panel has obvious marks of separation, integration, test, and extraction. The drawer unit is equipped with a mechanical interlock. The drawer unit is the main body and has both withdrawing and fixing type. It can be combined together, and used freely The protection grade of the cabinet is IP30, also it can be customized.
