High voltage switch cabinet
High voltage switch cabinet is used for power system of power generation, transmission, distribution and power conversion and consumption of on-off and control or protect, voltage grade in 3.6kV~550kV electrical products, mainly including high voltage circuit breaker, high voltage disconnecting switch and grounding switch, high voltage load, high pressure automatic reclosing and sectionalizer, HV operating mechanism, high-pressure explosion-proof power distribution equipment and high voltage switch cabinet and so on. High voltage switchgear manufacturing industry is the power transmission equipment manufacturing industry is an important part of, in the electric power industry occupies very important position.
Composition of switch cabinet
Switchgear shall meet the GB3906-1991 "3-35 kV AC metal closed switch equipment" standard requirements, consists of two parts, the cabinet and the circuit breaker, cabinet is composed of a casing, electrical components (including insulation), a variety of institutions, the second terminal and connection etc..
Cabinet material
1) cold-rolled steel sheet or steel for welding cabinet); 2) aluminum zinc coated steel plate and galvanized steel (for assembled cabinet). 3) stainless steel plate (magnetic). 4) aluminum ((magnetic). 2. The cabinet function unit: 1) main busbar chamber (general main busbar arrangement according to the "triangle" or "1" glyph 2) circuit breaker chamber 3) cable chamber 4) relay and instrument room 5) cabinet top of a small bus room 6) second terminal room
