Everyone has many household appliances, from air conditioners to refrigerators to computers, televisions and electric fans. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. IP54, that is, dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. There are many household appliances, but it is impossible to install so many. Fix them on the wall with the skin switch on the wall. At this time, the necessity of socket appears, so in the same situation, because there are many industrial devices, industrial plugs are also essential. Our electricity consumption is 220v, so the voltage limit of all electrical appliances in our home is 220v, and the working voltage of industrial plugs and sockets is 380v. This is because there are a lot of power equipments that consume a lot of electricity, and the household voltage can't meet their start-up. The emergence of industrial plugs is to meet everyone's needs.At present, most household plugs and sockets do not have strict protective measures, but the protective measures for industrial plugs and sockets are very strict, and the connection of industrial plugs and sockets is equipped with anti-falling devices and excellent fire prevention devices. The anti-falling device can prevent the industrial plug and socket from being separated naturally when being broken. There is also a fire prevention measure, which is equivalent to the plugs and sockets we use everyday. Sometimes, when the plugs are turned on, there will be lights flashing. Industrial plugs and sockets are also a phenomenon. However, fire prevention measures are designed to prevent this situation, even if there is a flash, it will not affect the objects nearby.Sockets that we don't use at home are usually scattered directly there, which is the same in the industry. We don't have a good habit of sorting out long-term industrial plugs. Whether it's a socket or an industrial plug, it's best to clean it up if it is not used for a long time.When industrial plugs and sockets are not used or cleaned for a long time, some dirty things such as dust will slowly accumulate between the north and south poles of the plugs and the sockets of the sockets, and when the dirty things such as dust accumulate more and more, they may also become conductors, which will eventually make the power supply in an energized state. This situation is called dirt accumulation and conduction. Under normal circumstances, it will lead to poor contact of the circuit. If the situation is serious, it will also lead to partial heating of the industrial plug and deformation of the insulating resin of the industrial plug and socket, which will lead to short circuit and fire.These conditions may be less developed in summer or other drier environments, so no one pays much attention to them, but the above problems are likely to occur in humid air environment in autumn and winter.
