Low voltage switch cabinet Fundamentals training materials vacuum switchgear basics in actual use multiple vacuum breaker into the metal cabinet, Luoyang New low voltage, high voltage switchgear constitution. In addition to the circuit breaker switchgear, also install play the role of isolation circuit isolating switch, from the security role of the grounding switch, measure or protection from the effects of current and voltage transformers, from the over-voltage arrester or protective effect RC absorber, but also install secondary circuit components and circuits, connection of cables or overhead lines can be used for relay into the cabinet, the switch cabinet as a function of a combination of a relatively independent power distribution equipment. In switching stations, transmission lines power plant substation, receives power user terminal substations are extensive use of various switchgear. About 10 years ago, equipped with less oil circuit breaker switchgear occupies almost a monopoly in the country, Changge low voltage switch cabinet, but with the rise of a vacuum circuit breaker, low oil switch refuse gradually back seat. Since 1993 made 'oil-free transformation' requirements since, also contributed to this trend, some provinces even banned the continued use less oil switch refuse in the city grid and key users of the station building, while the old station is gradually be replaced with a vacuum switch less oil switchgear. MCB SZRB2-125SZRB2-125 series MCB for AC 50 or 60Hz, rated voltage of 400V and single phase 230V, rated current 125A and below the line, buildings and electrical equipment used to short-circuit , with overload protection, low voltage, but also under normal circumstances, as infrequent line conversion, but also to isolate the switch and as a line-voltage protection and long way off. The product appearance, small size, light weight, power trip setting precise, reliable action, high breaking capacity, tripping quickly, rail, combined mode design with auxiliary contacts, alarm indication contacts, undervoltage release , shunt trip accessory combination, to meet the needs of different users, the housing and components of high fire-retardant and impact-resistant plastic, long service life. This product complies with IEC60947-2 and GB14048.2 standards.
