Flameproof electrical equipment is greatly influenced by working conditions and environment during actual operation. Harsh environments can significantly affect the performance of Flameproof electrical equipment, and prolonged adverse effects can reduce its Flameproof capabilities, or even result in a complete loss of Flameproof performance. Typically, these adverse factors mainly include the following aspects:

Adverse Factors in the Operation of Flameproof Electrical Equipment

Humid Environment

Storing or operating flameproof electrical equipment in a humid environment for a long time can easily lead to a reduction in the electrical insulation resistance, damage to the insulation, causing leakage or breakdown of the equipment. Humid environments also damage the Flameproof performance of increased safety and non-sparking equipment, and have extremely adverse effects on the safe operation of flameproof or other Flameproof types of electrical equipment. Additionally, the humid environment can cause rust at the flameproof joints of the flameproof electrical equipment, creating potential safety hazards for safe operation.

Extreme Temperatures

Generally, the working environment temperature for flameproof electrical equipment is between -20℃ and +40℃. If the ambient temperature exceeds +40℃, it will affect the surface temperature and winding temperature of the equipment, causing its temperature to rise rapidly in working condition, thereby negatively impacting its Flameproof performance. On the other hand, long-term operation under high temperatures severely damages the electrical insulation performance of the equipment. This may cause the electrical equipment's shell to deform, accelerate the aging of components, worsen the operating condition, and reduce the Flameproof performance.

Strong External Impact

Flameproof electrical equipment subjected to strong external impact or vibration during operation can significantly affect its mechanical performance and strength, easily causing loosening or disconnection of electrical connections. Additionally, overloading the motor, frequent starts, and reverse braking conditions can lead to equipment overheating, reducing equipment lifespan and safety.

Corrosive Gases or Liquids

Corrosive gases or liquids from the external environment can easily damage the shell and insulation layer of flameproof electrical equipment, resulting in a significant reduction in Flameproof performance and protection rating. This can also cause poor electrical contact and electrical sparks during operation, posing great safety hazards to the surrounding production environment. Moreover, it can cause corrosion of electrical wires and cables, reducing their lifespan.

Safety Inspection of Flameproof Electrical Equipment

Visual Inspection

Mainly conduct daily inspections of the equipment's external damage and integrity.

Professional Equipment Testing

During maintenance, any potential safety hazards can be identified and tested for Flameproof electrical performance and safety using professional electrical maintenance equipment. This will help determine if there are any hidden dangers in the equipment's operation. Professional equipment testing usually involves periodic inspection.

Special Inspection

This inspection generally occurs during scheduled equipment maintenance, or can be conducted in response to common damages identified in flameproof electrical equipment, allowing for targeted special inspection work.
