Electrical power system equipment is referred to on the generators, transformers, power lines, circuit breakers and other equipment, electrical equipment which is installed with a certain degree of risk. Therefore, electrical equipment installation, we should pay attention to safety precautions following the installation of electrical equipment : 1, the metal casing of electrical equipment must be grounded or connected to ground zero to do the same equipment and the same supply network does not allow access to zero and some take some ground zero 2, the power transmission system and various types of high and low pressure switch.. When debugging, should be related to the switch handle removed or locked, hanging badges, to prevent accidental closing. 3, more than one distribution panel (box) heavy lifting and transport equipment when installed side by side, the fingers can not put two plates (box) The joint position, do not touch the screw and screw connections. 4, when installing high-pressure oil switch, automatic air switch to return to spring switching equipment, should switch to the off position. 5, the metal casing pressure test device shall be earthed at both ends of the cable under test equipment or, if not in the same place, the other side should be guarded or locked. of instruments, such as checking the wiring is correct, after the evacuation, before the boost. 6, electrical equipment or materials, as non-impact test, boost or buck, should be carried out slowly. reason to suspend or end the pressure test, you should cut off the power supply, safe discharge lifting equipment installation, equipment and boost the high side shorted to ground. 7, outdoor use electrical equipment, should have good performance or a reliable rain rain facilities. distribution box must be strong, complete and rigorous use of the distribution box placed debris is prohibited. 8, current transformers prohibit open, the voltage Do not short and transformers to boost mode. 9, electrical equipment all fuses (kg) should be rated for its load capacity to adapt. prohibit the use of other metal wire instead of a fuse (piece) 10. When handling distribution cabinet, should When there is someone directing, acting in unison. 11, tick tank, lifting equipment when lifting holes, must wear protective glasses, a hammer handle not loose. chisel not curl, crack. played walls, floors through the eye wall back, not someone close to the floor below. often use a crane who, in the course of lifting equipment handling equipment, the use of a crane operator, crane hoists shall make stayed oblique, that hoisting rope hanging objects through the center of gravity and perpendicular that allowed the oblique oblique hanging. Many people do have some questions, why not oblique crane hanging it? a crane hanging oblique possible overload hypothesis lifted from the ground on the weight of the object Q, vertical lifting, rope tension S As long as Q is equal to or slightly larger than Q, the weight can be off the ground. However, if the oblique, and wire rope to the ground at an angle to the vertical. According to the principles of mechanics, the rope tension acting on the S, can be decomposed into an object vertically upward The force P and the horizontal movement of the force F, to make the objects hanging from the floor, P F at least equal to Q. As the same time the angle increases. That is, the larger the angle of the swash hanging time, the hanging The same heavy objects rope when the force is greater. Therefore, if a heavy load full vertical lifting, then there must overload oblique hanging, rope and even pulled off the accident occur. 2, crane hanging oblique produce inertia force, endangering another person around, hanging oblique generated when the horizontal component of F, while leaving the ground in front of the weight is affected by friction. In an instant off the ground, will enable objects to the vertical center of the swing, it is possible and hang hanging staff worker or other objects around the collisions caused by an accident. In short, if oblique hanging, not only will cause overload pull off the rope, and make heavy swing squeeze hit objects and people, causing personal and equipment accidents equipment lifting handling company | Sunshine lifting equipment | Lu in the company's services are provided by Shandong Lu first mechanical equipment installation Limited.
