At present, the primary industry in society is the most important industry, and the development of industry is the embodiment of a country's development, and the degree of industrial development is closely related to the country's overall development. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt commutation device quickly and braking device effectively. However, industrial plugs are often used in industries that we often say. What are industrial plugs, and what significance do industrial plugs have for industrial production and development? But most of us haven't touched industrial plugs, so we don't know the purpose and function of industrial plugs, but we only need to know that industrial plugs are an indispensable tool in industrial production and have powerful functions, the existence of this socket box and its uniqueness and importance.Because industrial plug boxes are widely used, with the development of science and technology, there are more and more types of industrial plug boxes. Industrial plugs are suitable for outdoor places such as various industries, electric power industry, railway industry, chemical industry, coal industry, automobile industry, shipbuilding industry, container terminals, airports, large amusement parks, steel industry, industry, construction, food industry and tertiary industry.At the same time, we can give him some definitions about industrial plugs.Structural characteristics of industrial plugsAccording to the installation mode: it can be divided into mobile type, open type and concealed type;According to whether the socket box is equipped with protective devices: no protective devices, fuses and micro-circuit breakers;According to whether the socket box is equipped with interlocking device, it is divided into: without interlocking, with mechanical interlocking and with interlocking;According to whether the outlet box is equipped with a safety transformer: no transformer or transformer;The general configuration of the power box is as follows1. The outer box is made of practical engineering plastic aluminum alloy +ABS shell by die casting, and then the surface is sprayed with plastic to beautify.2. Internal parts such as Chint, Schneider and abb are commonly used;3. The socket box has the function of overload short-circuit protection in use safety, which can protect the use safety of the circuit;4. With advanced modular structure and various circuits, users can freely choose and assemble according to their own needs;5. It can also be specially installed according to the special requirements of users, such as surge protector, ammeter, voltmeter and other internal components; And a padlock and a metal handle can be arranged on the outer box body.6. Steel pipes are used for cable wiring.The characteristics of industrial plug boxes are different from those of ordinary households. Industrial plugs are more durable and of very good quality. The production materials are all high temperature resistant and fireproof materials, and the chemical properties of these materials are more stable. At the same time, the box material can also be flame retardant, self-extinguishing, aging resistant and good in thermal stability. Generally, the choice of industrial plugs is European-style sockets, so the more round the European-style sockets, the more cards they bring, so general equipment is not suitable for use. When it is used with our ordinary household socket, you need to add an adapter to use it. Therefore, our industrial plugs generally need to be customized according to customer requirements. Ask customers to provide the size information of the boxes they want, as well as the specifications of industrial plugs and the brands needed for switches.
