Cause Analysis of Frequent Damage to High-Voltage Packs on Burners in Tire Pyrolysis Oil Production Equipment

Considering the high-temperature and high-dust operating conditions of tire pyrolysis oil production equipment, the main causes of frequent high-voltage pack damage can be categorized as follows:

1. Damage Caused by Severe Working Environment

High-Temperature Baking and Inadequate Heat Dissipation

The burner is adjacent to the high-temperature zone of the pyrolysis furnace. Long-term exposure to radiant heat accelerates the aging and embrittlement of internal insulating materials in the high-voltage pack, leading to electric leakage or breakdown. If the equipment lacks an effective heat dissipation structure, accumulated heat will burn out internal components.

Dust and Oil Contamination

Carbon black dust and oil-gas generated during oil refining adhere to the surface of the high-voltage pack. Once they penetrate the interior, they damage insulation performance, causing inter-turn short circuits or external arcing in the coil, and eventually burning out the high-voltage pack.

Severe Vibration Impact

Vibration from the burner during operation loosens internal solder joints and shifts coils in the high-voltage pack, leading to poor circuit contact or short circuits, which in turn cause high-voltage pack failure.

2. Damage Caused by Abnormal Electrical Systems

Voltage Fluctuations and Overload

Unstable power supply voltage or excessively high ignition frequency of the burner places the high-voltage pack in a long-term overload state, resulting in excessive internal current that overheats and burns the coil.

Circuit Faults

Short circuits, open circuits, or poor contact in the ignition circuit generate instantaneous high-current surges that exceed the high-voltage pack’s load capacity, causing damage.

Spark Plug Malfunctions

Carbon deposits, electrode wear, or abnormal gaps in the burner spark plug lead to insufficient ignition energy, forcing the high-voltage pack to continuously output higher voltage. This increases the load and accelerates aging and damage.

3. Product Quality and Maintenance Issues

Inherent Quality Defects of the High-Voltage Pack

If the selected high-voltage pack is not suitable for high-temperature industrial conditions or uses low-quality insulating materials, its temperature resistance and corrosion resistance will be insufficient, leading to early failure or frequent damage.

Inadequate Maintenance

Failure to regularly clean dust and oil from the high-voltage pack surface or inspect circuit connections allows hidden risks to accumulate, eventually triggering faults.
