Overview
photovoltaic grid-connected cabinet is suitable for power distribution systems with AC 50Hz, rated working voltage 380V and rated working current 2000A of power users such as centralized ground, series ground and distributed ground, and is used for power conversion, distribution and control of power, lighting and power distribution equipment.
products have the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure and high protection level. Can be used as a low-voltage switchgear replacement products.
AC low-voltage distribution cabinet in line with IEC439 "low-voltage switchgear and control equipment", GB7251 "low-voltage switchgear" and other standards.
Normal use environment
◆ The ambient air temperature is not higher than 40 ℃ and not lower than -5 ℃. The average temperature within 24h shall not be higher than 35 ℃.
◆ For indoor installation and use, the altitude of the use place shall not exceed 2000m.
◆ The relative humidity of the surrounding air does not exceed 50% at the highest temperature of 40 ℃, and a larger relative humidity is allowed at lower temperatures. (For example, 90% at 20°C) The effect of accidental condensation due to temperature changes should be considered.
◆ When the equipment is installed, the inclination of the vertical plane shall not exceed 5%.
The equipment should be installed in the place without severe vibration and impact, and not enough to make electrical components subject to corrosion.
◆ When the user has special requirements, negotiate with the manufacturer.
