1) Whether the type, specification and quantity of the components used meet the requirements of the drawings;
2) Whether the installation and layout of components meet the process requirements;
3) The indicators, buttons, and meters on the panel should be horizontal and vertical (design should also consider ergonomic requirements, such as buttons, meters, etc. cannot be installed too high or too low, otherwise operation and observation Are inconvenient);
4) Whether the components have complete signs, nameplates, and whether the contents on the labels are correct; Xiangtai Electric-Low Voltage Switchgear
5) Whether the component installation is reliable, reasonable and meets the installation requirements of the component manufacturer (for example, some components can only be installed vertically, horizontal installation is not allowed, and some are not allowed to tilt, etc.).
6) Also check whether the electrical clearances and creepage distances of live parts in electrical components and functional units meet the requirements, and whether the arcing distances of circuit breakers and AC contactors are qualified.
7) The distance between live conductors such as exposed live terminals of electrical components and metal components (such as frames, partitions, door panels, etc.) must not be less than 20㎜, and insulation measures must be taken if the requirements are not met. There should be baffles between the fuses of each phase to prevent the adjacent fuses from being affected when the fuse of one phase is blown.
