Electrical Appliances: How To Make The Correct Layout And The Circuit In The Distribution Box
The correct distribution box line configuration can save time and circuit, which requires us to master certain technology and skills, according to these skills to wiring, in order to achieve the effect. The power distribution cabinet distributes the electric energy of a circuit of the upper power distribution equipment to the nearest load. This equipment shall provide protection, monitoring and control of the load. The power cabinet is a combination of electrical control cabinets that provide power for the normal operation of the whole machine, including fuses, circuit breakers, contactors, frequency converters, high-voltage cabinets, transformers, etc. According to the electrical wiring, the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are required to be assembled in closed or semi enclosed metal cabinet or on the screen to form a low-voltage distribution box. In normal operation, the circuit can be connected or disconnected by manual or automatic switch. Necessary safety measures shall be taken for power distribution equipment, such as covering or placing dangerous naked charged body outside the range of people's outstretched arm. The correct line configuration scheme can save time and line, which requires us to master certain technology and skills, and to wire according to these skills, so as to achieve the effect.
First, location. The low-voltage power distribution location should be close to the load center of the chamber, providing less dust, less corrosive medium, dry and slight vibration, and should leave room for appropriate development; 2. The layout of power distribution equipment. The layout of low voltage distribution room shall follow the principles of safety, reliability, economy and applicability of distribution equipment, and shall be convenient for installation, operation, treatment, maintenance, testing and monitoring. In the same chamber between the high-voltage electrical equipment and the low-voltage electrical equipment, the rows arranged between the power distribution cabinets have left an appropriate distance and the outlet channel. Necessary safety measures shall be taken for the layout of power distribution equipment. If the potential risk caused by naked charged body is beyond the scope of human shielding arm, it shall be added or placed. When the baffle and the shell are difficult, the three conditions that can be protected should meet the barrier of distribution line layout: the line with the characteristics of the workplace environment; the compliance function of the building; the degree of accessibility between people and wiring; due to the possible occurrence of the electromechanical stress short circuit; and; Other stresses and conductors during the installation or operation of wiring may be affected, and the weight distribution lines shall be arranged to avoid the external environment: the thermal effect of external heat source shall be avoided; the water intrusion into the body or the damage caused by being brought into use shall be prevented; external mechanical impact damage shall be prevented by stopping the belt; Instead of a large amount of dust should be avoided due to the impact of wiring to dust accumulation; to avoid damage due to strong solar radiation.
