ZMNS-0.4 low-voltage cabinet details of the cabinet frame modulo the C = 25mm profiles, through a variety of connectors, self-tapping screws and hex bolts, the frame structure without special tools that can be assembled into various forms cabinet properties with high strength and flexibility. multifunction breaking isolation plate is installed between the main bus room and electrical room, engineering thermoplastic material used is made with a high flame, high strength and high impact can be effectively prevent accidents caused by a short circuit between the arcing caused by the switching element due to failure with the bus. using standard modular design, the cabinet according to customer requirements can be combined into a chest of drawers, fixed counters, cabinets and fixed compartment mixed cabinet, drawer unit standard Specifications are 8E / 4,8E / 2,8E, 16E and 24E (E = 25mm) five specifications, the same size drawers can be easily interchanged by the operating handle and large interlocking drawer can be accurately positioned in the connection, experiment, separate and move the location of each position on the front panel has a corresponding logo, simple, intuitive when the circuit breaker closing, mechanical interlock drawer movement ban in order to ensure safe operation of enclosure protection class:... IP30 , IP40. Low voltage switch cabinet Fundamentals training materials vacuum switchgear basics in actual use multiple vacuum breaker into the metal cabinet, composed of high voltage switchgear. 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 district opened high and low voltage, the switch cabinet has become a relatively independent composition distribution function devices. 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, but with the rise of a vacuum circuit breaker, low voltage switch Gongyi City, refused to progressively less oil switch back seat. Since 1993 made 'oil-free transformation' requirements since, low voltage, but 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, The old station will gradually be replaced with a vacuum switch less oil switchgear.
