summary
blokset low voltage switch cabinet can be used in low-voltage systems all require high reliability: electrical distribution system and electric control system. widely used in industrial and mining enterprises, high-rise buildings, municipal construction and other types of low-voltage system; products comply with gb7251.1, gb/t23359, jb/t9661 and other relevant standards.
blokset type low voltage switch cabinet has the following obvious characteristics：
1.overall: it is a complete system of integrated schneider electric switch element, the protection equipment is designed according to the optimization of the coordination;
2.reliability is designed and tested in accordance with international standards;
3.modular: by the standard prefabricated components, can be quickly made, easy to modify and save costs.
4.intelligent: components that can contain advanced protection and communication functions are integrated into the device for use in power distribution and motor protection.
conditions of use
indoor ambient temperature: not low dry -5 c, not higher than +40℃, the average is not higher than +35℃
altitude: not more than 2000m
relative humidity. when +40℃ is not more than 50℃, the lower temperature allows a higher relative humidity (up to 90% when the ambient temperature is 20℃).
earthquake basic intensity: no more than 7 degrees
protection level：ip30、ip43、ip54
blokset structure characteristics
1.the switch cabinet is a drawer type structure and a fixed separation structure. the height of each cabinet is 40 modules. each module is high 50mm. drawer bus: single occupy 6 double modulus, occupy 10 main bus modules; the other cabinet: single occupy 4 double modulus, occupy 8 modulus, for the rest of the switch function unit effectively occupy the installation module.
2.multi-functional modular power distribution cabinet is divided into: a) (d) b) power factor compensation cabinet (dc) c) motor control center (mf) fixed type) d motor control center (cabinet drawer type mw type) e) converter and soft starting cabinet (type ms) f) distribution box (c type)
3.the cabinet is composed of the basic framework and framework and basic framework, and by the standards of prefabricated and assembled with various specifications. these components can be assembled into frames of different sizes. the basic frame and the extended frame can be combined to form a variety of depth and width of the switch cabinet.
3 kinds of depth, 6 kinds of width：
depth: 400mm, 600mm, 1000mm, by a 400mm and a 600mm depth of the basic framework of the composition. width: 500mm (mw type), 700mm, 900mm (mw type), 1200mm (for mt40b/5o masterpact / 63), according to the need, can be in the 700mm wide basic frame on both sides to increase the expansion cabinet (200mm or 400mm).
4.the switch cabinet is divided into a bus bar room, an element room, an outlet cable chamber and an auxiliary part room by using the grounding metal partition board, and the partition form of the compartment is 1, 2b, 3b, 4a and 4b in five forms.
5.switch element mounting method has the fixed, the insert type, the drawer type.
functional units in the drawer height specifications are: 300mm, 150mm, 450mm, 600mm, 750mm. the required switching elements are installed in a drawer of the switch cabinet, which can ensure the rapid and reliable maintenance and repair.
insert switch and other components can be installed in a fixed unit interval, according to the different height of the fixed interval switch and other components of the size, generally 150mm, 300mm, 450mm, 600mm and other high. fully independent, safe and reliable between different intervals.
