Fengheng Technology provides professional heat dissipation solutions for the power equipment industry. Its products are widely used in high and low voltage switchgear, distribution cabinets, prefabricated substations, dry-type transformers, ring main units, medium-voltage switchgear and other equipment, meeting the stringent requirements of power equipment for high reliability, moisture and condensation prevention and long service life.<\/p>\n

\n

I. Four Core Pain Points in Power Equipment Heat Dissipation<\/h2>\n

Pain Point 1: High temperatures inside the cabinet shorten the lifespan of the equipment.<\/h3>\n

Phenomenon:<\/strong>Excessive internal temperature in switch cabinets and distribution cabinets accelerates the aging of components such as circuit breakers and relays.<\/p>\n

root cause:<\/strong>Hot air inside the cabinet cannot be effectively expelled, causing heat to accumulate.<\/p>\n

Industry data:<\/strong>For every 10\u00b0C increase in temperature, the lifespan of electrical equipment decreases by approximately 501 TP3T.<\/p>\n

Pain Point 2: High requirements for waterproofing and moisture-proofing of outdoor distribution boxes<\/h3>\n

Phenomenon:<\/strong>Outdoor distribution boxes and box-type substation fans malfunction after being exposed to water or moisture, leading to condensation and short circuits inside the cabinet.<\/p>\n

root cause:<\/strong>It uses a regular fan instead of an IP-rated fan and has no anti-condensation design.<\/p>\n

Industry Standards:<\/strong>Outdoor electrical equipment typically requires IP54, IP55 or higher protection ratings.<\/p>\n

Pain Point 3: The requirement for high reliability during 24\/7 continuous operation<\/h3>\n

Phenomenon:<\/strong>Electrical equipment operates continuously year-round, and insufficient fan life leads to heat dissipation failure.<\/p>\n

root cause:<\/strong>Inexpensive oil-bearing fans have a lifespan of only 10,000 to 20,000 hours, far below the design lifespan of electrical equipment.<\/p>\n

Industry data:<\/strong>Electrical equipment is designed for a lifespan of 20-30 years, and fans must be maintenance-free for 5-10 years.<\/p>\n

Pain Point 4: Safety Insulation Requirements in High-Voltage Environments<\/h3>\n

Phenomenon:<\/strong>The fan inside the high-voltage switchgear has insufficient insulation, posing a potential safety hazard of leakage.<\/p>\n

root cause:<\/strong>The fan was not reinforced with insulation.<\/p>\n

Industry Standards:<\/strong>Fans inside high-voltage equipment need to have enhanced insulation and withstand voltage \u22652.5kV.<\/p>\n

IV. Key Points of Heat Dissipation Design for Power Equipment<\/h2>\n

1. Cabinet ventilation design<\/strong><\/p>\n

    \n
  • The air inlet and outlet need to have sufficient area to form effective convection.<\/li>\n
  • The air inlet and outlet positions should be staggered to avoid airflow short-circuiting.<\/li>\n
  • A bottom-in, top-out air duct design is recommended.<\/li>\n<\/ul>\n

    2. Moisture-proof and condensation-proof design<\/strong><\/p>\n

      \n
    • Outdoor equipment should have at least IP55 protection.<\/li>\n
    • Dehumidification with heater, fan-assisted circulation<\/li>\n
    • The cabinet must be well-sealed to prevent moisture from entering.<\/li>\n<\/ul>\n

      3. Insulation and Safety Requirements<\/strong><\/p>\n

        \n
      • The insulation of the fan inside the high-voltage equipment needs to be strengthened.<\/li>\n
      • The fan power cord must have a protective sleeve.<\/li>\n
      • The installation location should avoid exposed live parts.<\/li>\n<\/ul>\n
        \n

        V. Frequently Asked Questions (FAQ)<\/h2>\n

        Q1: How long can the fan in a switch cabinet typically last?<\/h3>\n

        A: Original factory AC oil-impregnated bearing fans typically last 3-5 years. Fengheng AC dual ball bearing fans can last 8-10 years.<\/p>\n

        Q2: What should I do if water gets into the fan of an outdoor distribution box?<\/h3>\n

        A: We selected an IP55 protection-rated fan. The Fengheng IP55 series is rainproof and dustproof, making it suitable for outdoor installation.<\/p>\n

        Q3: What specifications of fan are used in a prefabricated substation?<\/h3>\n

        A: The prefabricated substation has a large space, so large-size fans (20060, 25489) need to be selected to ensure sufficient ventilation.<\/p>\n

        Q4: Are there insulation requirements for the fan inside the high-voltage switchgear?<\/h3>\n

        A: Yes. The fan inside the high-voltage switchgear needs enhanced insulation design, with a withstand voltage of \u22652.5kV to ensure safety.<\/p>\n

        Q5: Do you support sample testing?<\/h3>\n

        A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.<\/p>\n
