Mnsz type low voltage draw out switchgear






Product category: Product Center switchgear Series Product Description: compact design, strong universality, high safety, easy assembly details Equipment Overview: mnsz low voltage draw out switchgear is a combined low voltage switchgear assembled with standard module (hereinafter referred to as device). The device is suitable for power supply and distribution system with AC 50 (60) Hz, rated working voltage 380V and below. Used for power generation, transmission, energy conversion box and energy consumption equipment   The control of the system.         The device conforms to iec60439-11999 Part V, gb7251.1-1997 low voltage switchgear and control equipment and JB / t9661-1999 low voltage draw out switchgear.   Product features: the device was developed in the late 1990s. After many improvements, it is at the leading level in China. Compact design: it can hold more functional units in a small space, and can hold up to 36 8e / 4 drawer units. The C-type material with 25 mm modulus can meet the requirements of various structural forms, protection levels and use environment. Adopt standard module design: it can form protection, operation, conversion and other standard units, and users can choose and assemble them according to their needs. With more than 200 kinds of assembly parts, the frame structure and drawer unit of different schemes can be formed. High safety: a large number of high-strength flame-retardant engineering plastic components are used to effectively strengthen the protection safety performance, with anti arc design and personal safety guarantee for operators. High technical performance: the main parameters reach the contemporary international technical level. The cold plate or aluminum zinc coated plate is used for the plate, and the cabinet is maintenance free. It is convenient to update and improve the equipment.     Service conditions: ambient air temperature not higher than + 40 ℃, not lower than - 10 ℃, average temperature within 24 hours not higher than + 35 ℃. Atmospheric conditions: the air is clean, the relative humidity is not more than 50% when the maximum temperature is + 40 ℃, and a larger relative humidity is allowed when the temperature is lower, such as 90% when the temperature is + 20 ℃. However, considering that humidity condensation may occur occasionally due to temperature change. For indoor use, the altitude of the place of use shall not exceed 2000m. The device is suitable for transportation and storage at the following temperatures: - 25 ℃ to + 55 ℃, and can reach + 70 ℃ in a short time (no more than 24 h). Under these extreme temperatures, the device conditions shall not be damaged irrecoverably. If the above service conditions cannot be met, the user and the manufacturer shall negotiate to solve the problem. When the unit is used with offshore drilling and production platform and nuclear power station, a separate technical agreement shall be signed.
