The safety performance of Power Distribution Cabinet is a crucial link in the power system, and its protection involves many aspects. First of all, from the perspective of design and material selection, the outer shell of the Power Distribution Cabinet should be made of heat-resistant and flame-retardant materials to prevent fires caused by external fire sources. At the same time, the internal high-temperature components must also use high-temperature-resistant materials to ensure that overheating does not occur during long-term operation. In addition, for electrical insulation, insulating materials, such as insulating boards, should be used, and protective sleeves should be installed at the contact points between wires and brackets to avoid electric shock accidents.
In terms of protective measures, Power Distribution Cabinet requires reliable grounding measures. The setting of grounding wires, inspection and maintenance of grounding devices, and grounding in accordance with relevant national regulations are key steps to ensure that no contact current will occur when equipment or personnel are energized. At the same time, fire prevention measures are also essential, including establishing fire escapes and setting up fire extinguishers to deal with possible fire accidents.
In addition to the above basic safety measures, the installation and maintenance of Power Distribution Cabinet are also important aspects to ensure its safety performance. Power Distribution Cabinet and switch box should be installed upright and firmly, and should not be inverted or skewed, and the vertical distance between the bottom and the ground should meet relevant standards. In addition, it is strictly forbidden to use plug connections for power cords entering the Power Distribution Cabinet. A safer and more reliable connection method should be used. Each electrical equipment should have its own dedicated switch box and must meet the requirements of "one machine, one gate and one leakage" to avoid safety accidents caused by misoperation.
In daily use, users should use electrical equipment strictly in accordance with the rated power of the equipment to avoid overheating or short circuiting the circuit due to overload use. At the same time, it is necessary to regularly check the operating status of Power Distribution Cabinet to discover and solve existing problems in a timely manner. It is also very important to keep the area around the Power Distribution Cabinet clean to prevent dust and debris from entering the Power Distribution Cabinet and affecting the heat dissipation and normal operation of the equipment.
To sum up, the safety performance guarantee of Power Distribution Cabinet is a comprehensive work, involving many aspects such as design, material selection, installation, maintenance and daily use. Only by comprehensively considering and strictly implementing these measures can the safe and stable operation of Power Distribution Cabinet in the power system be ensured.
