I. Common problems in the use of industrial plugs and sockets1. The waterproof cover is not fastenedUnfastened waterproof covers of industrial plugs and sockets seriously affect the waterproof performance of industrial plugs and sockets, especially in some outdoor environments that are easily exposed to rain. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack. 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. 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.2. Unplug without removing the anti-dropping knot.Industrial plugs and sockets all have anti-dropping structure. When inserting or unplugging, you must hold the handle of the plug first, then open the cover of the splash-proof socket or loosen the bayonet for unplugging, otherwise it will get stuck and can't be pulled out. If you use brute force to pull and plug, the plug or socket will be smooth.3. Pull out the plug when interlocking.For some industrial plugs and sockets with interlocking function, it is only when the switch is in the power-off state that the plug can be unplugged, but when the switch is powered on, the socket will lock the plug and cannot be unplugged. However, there are always some people who don't understand this situation. When the interlocking device is powered on, it is pulled out by brute force, which eventually leads to the industrial plug interlocking device being scrapped.4. Pull the cable and unplug it.General industrial plugs with internal cable clamps are generally not easy to pull out. But there are always some users who always unplug the cable, which will cause cable damage over time.5. Store industrial plugs at will.6. Plug in the industrial plug directlyIn reality, there are always many people who do not directly connect the wires to the plugs and sockets for convenience, which is a very common mistake in industrial plugs and sockets, but the consequence is very dangerous, because the connection between the wires and the copper core inside the sockets is not tight, and it is easy to give off heat when used with electricity, so long-term use will cause damage to industrial plugs.7. Wrong protection levelGenerally speaking, IP67 can be used instead of IP44 industrial plugs in places where IP44 industrial plugs are needed, but IP44 can't be used instead in places where IP67 industrial plugs are needed. Improper use of the protection level will affect the performance.Second, prevention methodsIn recent years, in news or online reports, we often see accidents such as fires caused by improper use of industrial plugs and sockets, so we must take certain preventive measures to protect their lives and property to the maximum extent. By summarizing some common problems in the use of industrial plugs, we now provide you with some preventive methods to learn.1. Industrial plug socket is an advanced technology introduced from abroad in recent years. Many people are not familiar with the professional knowledge in this field and some special structures of industrial plugs and sockets, and common-sense mistakes are easy to occur in the installation process.
