For a long time, it has been known that the unqualified quality of industrial plugs and sockets can easily lead to accidents. 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. 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. 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. Some time ago, a worker of an electrical appliance company suddenly yelled and fainted when testing an electric fan. There was a 2 mm click black spot in the vein of the right wrist. After the rescue failed, he died. The reason is very simple, that is, the unqualified industrial plugs and sockets were purchased, which caused such an accident; Therefore, the quality of products is very important.So speaking of electricity, where does it come from? The insulation resistance of the aluminum frame of the fan winding was measured by 1000v oscillograph, and abb industrial plug reached 700 ohms. Therefore, the electric shock cannot be caused by the leakage of the fan. It is understood that there is a movable wooden block on the counter with four single-phase three hole socket, of which three socket grounding holes are located at the top, four socket grounding holes are located at the right, socket phase holes are located at the right, socket phase holes are located at the left, and industrial plug socket phase line holes are located at the top. The center-to-center distance between the two holes is 14.7mm.. The center distance between the big hole and the two small holes is 15.2 mm The positions of these three holes are similar to those of a regular triangle.First, it ranks high, and the socket board devices should be neat and consistent. Generally viewed from the front of the socket, they are arranged clockwise as: ground (e), phase (a) and neutral line, and the bottom of the socket is often marked.Second, the arrangement of the plug should be able to prevent contact with charged objects and prevent one foot (that is, one foot is inserted into the human body and the other foot is outside).Third, the three-core wires on the plug should be connected correctly. The core parts of the connection box should not be misconnected to avoid electrification.Especially for industrial power consumption, we should pay more attention to the purchase and use of industrial plugs, and choose qualified industrial plugs and sockets, because industrial power consumption is greater!Zhejiang Co., Ltd. provides industrial plugs, industrial plugs, connectors and other connector products.
