Tianjin distribution box manufacturers / distribution box price in the domestic supply and distribution system and the United States in the distribution cabinet models there are many, they are the cabinet structure or technical parameters are different. Under the influence of the following factors, often need to modify the design of a good drawing, or even re-design, it will not only affect the construction plans for the distribution system, power distribution cabinet manufacturers back in time to complete the distribution cabinet shelf production brought a certain problems. Drawing influence has been designed to change the factors are as follows: 1. Distribution Cabinet recommended by the manufacturer's own production of the product may not be suitable for the user to user. 2. The institute for some new container type and do not quite understand just be designed according to user requirements. 3. The user does not fully understand their own needs, not according to their own needs to choose when selecting cabinet types. To solve these problems, to meet user needs more accurately select specific distribution cabinet model, the following power supply system for the domestic characteristics of commonly used for analysis of low voltage distribution cabinet. Next, the inlet distribution cabinet cabinet structure or technical parameters for analysis. The main features of the domestic distribution cabinet is the specific model of the same type of domestic distribution cabinet manufacturers produced inconsistent, the specific structure of the distribution cabinet is also somewhat different, the main electrical components installed in the distribution cabinet can also be imported brands for domestic brands. The following description of the relevant technical parameters. 1. The maximum rated current of the main bus: the main bus can carry a maximum current rating. 2. Rated short time withstand current:, Plants in a strip circuit under test conditions in the national standards GB7251.1-2005 8.2.3 can be safely carried prescribed short time withstand current rms value given by the manufacturer . 3. Peak short time withstand current: under specified test conditions specified by the manufacturer of this circuit can successfully withstand the peak current. 4. Protection class: According to prevent contact with live parts IEC60529-1989 standards provided by the equipment, as well as the invasion of exotic solid and liquid entry levels. See detailed classification IEC60529 standards. 5. Internal separate ways: according to IEC60529-1989 standards to protect the personal safety of the switchgear independent divided into several compartments of different ways. Technical parameters between different types of distribution cabinets have very different technical parameters and the basic import distribution cabinets are better than domestic distribution cabinet, but it does not consider the import and distribution cabinet to be good than domestic distribution cabinet . Here the actual work experience, to talk about the following: 1. import distribution cabinet is developed abroad, are generally available for distribution for the global market. Due to the requirements of each country for the distribution system and habits are not the same, so the import and distribution cabinet is not necessarily fully applicable in the domestic market. 2. The main electrical components used in the import and distribution cabinets are imported brand products, some cabinet or some cabinet accessories must be imported, so causing the price of imported power distribution cabinets higher than normal number of domestic distribution cabinet . 3. Imported distribution cabinet technical parameters, although high, but in most cases only the use of a part, or even simply can not use. Such as the number of imported loop distribution cabinet can be installed in a cabinet than the domestic distribution cabinets are more, but that is the premise of reducing the capacity of the circuit can be achieved, in most cases can not meet user needs. Technical parameters 4. Although domestic distribution cabinet distribution cabinet lower than imports, but in most of the domestic power supply system has been able to meet user needs. 5. On the quality of the distribution cabinet, as long as the manufacturers in strict accordance with the requirements of 3C Manufacturing and testing, quality domestic distribution cabinet is not necessarily worse than the quality of imported distribution cabinet. Therefore, the choice of distribution cabinet models, should do the following: 1. Understand the desired user, the user select the most suitable type according to the actual situation of the cabinet. 2. Try using well-known manufacturers of domestic container type, not blindly choose the technical parameters relatively high import distribution cabinet, this could easily lead to a waste of resources. 3. Due to the distribution of imported brands and cabinet cabinet adopted the main components are the same. So choose to import distribution cabinet, should pay attention to the parameters of the main components, it must be able to meet user needs.
