1. Ensure Proper Insulation Based on Environment
Typically, the temperature range required for high and low voltage switchgear is between -10℃ and 45℃. If the ambient temperature is too high, the conductivity of metal components decreases while resistivity increases, oxidation accelerates, and the insulation strength of insulating components deteriorates. Conversely, excessively cold environments can cause significant internal stress in equipment components, compromising the reliability of insulating parts. Therefore, it is necessary to add reinforced insulation-type electrical components and insulation protective measures as needed. The surrounding environment should be free of ignition sources, pollution, and corrosive chemicals.
2. Implement Proper Dust Prevention and Inspection
Metal equipment on high and low voltage switchgear should be coated with appropriate paint for rust and corrosion prevention. To eliminate the impact of dust accumulation on insulation performance, dust inside the equipment should be regularly cleaned with a brush. For frequently operated switches, regular inspection of fixing screws for looseness is required, along with lubrication and tightening.
3. Ensure Proper Internal Wiring of High and Low Voltage Switchgear
Occasionally, due to production needs, temporary power may need to be drawn from the switchgear to supply high-voltage equipment. When wiring, strictly comply with electrical safety management regulations. Use insulated wires with good insulation performance, ensuring safety meets the load requirements. Wiring should be performed by professional electricians, ensuring smooth connections without knots, no intertwining between wires, and reliable grounding. When the temporary power supply is no longer needed, the additional power facilities should be promptly removed, and the site cleaned.
