Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power distribution cabinets, and particularly relates to an outdoor power distribution cabinet with temperature regulation. Background Art
[0002] The distribution cabinet is the final equipment of the power distribution system and is a general term for the motor control center. The use of distribution cabinets is very common in life, and different types of distribution cabinets are used according to different usage scenarios. In most areas, there is a temperature difference throughout the year, morning, noon and night, especially the temperature difference between summer and winter is large, and the fluctuation range can reach dozens of degrees. This makes the temperature of the distribution cabinet's use environment change, and its internal electrical components may not be able to adapt to the large temperature difference, which in turn affects its normal use. In particular, some distribution cabinets need to be installed outdoors, and most of the common outdoor distribution cabinets do not have a temperature regulation function and cannot adjust their internal temperature according to the temperature changes in the actual use environment.
[0003] First, low temperatures can cause the performance of insulating materials in electrical equipment to deteriorate, such as reducing dielectric strength and increasing insulation resistance, which may cause discharge, breakdown, or even short circuit failures. In addition, some non-metallic materials become more brittle at low temperatures, increasing the risk of rupture due to vibration or impact.
[0004] Secondly, under high temperature environment, the service life of electronic products in low-voltage distribution cabinet (such as residual current protection device, electronic instrument) will be greatly shortened. At the same time, high temperature will cause the performance of these devices to be unstable, the operation reliability will be reduced, and the measurement accuracy will be affected. High temperature may cause the electrical components inside the distribution cabinet to overheat, and then fail, including poor contact, short circuit, burning and other serious problems.
[0005] In summary, there are some problems in the use of outdoor distribution cabinets without temperature regulation function, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
