The fume extractor is leaking electricity

When the oil fume purifier vehicle experiences leakage during use, it not only affects the normal operation of the equipment, but may also pose a risk of electric shock to the operators. The solution to this problem needs to start with the analysis of the causes of electrical leakage, combined with professional investigation and safety measures, in order to completely eliminate hidden dangers. This article will revolve around“ Oil fume purifier vehicle leakage; This core issue requires a systematic review of possible causes, solutions, and prevention strategies.

1、 Common causes of electric leakage in oil fume purifiers

1. Equipment aging or circuit damage

The oil fume purifier vehicle is exposed to high temperature and high humidity environments for a long time, and the insulation layer of the internal circuit may break due to aging, corrosion, or mechanical damage, resulting in current leakage. For example, cracks in the outer skin of power cords, exposed copper wires inside, or loose connections at electric field components can all cause electrical leakage.

2. Grounding system failure

Grounding is a crucial link in ensuring electrical safety. If the grounding wire of the equipment is loose, broken, or the grounding resistance is too high, when leakage occurs inside the equipment, the current cannot be introduced into the ground through the grounding wire, but may be conducted to the human body through the equipment shell, causing the risk of electric shock.

3. Static electricity accumulation not released

During the operation of the oil fume purifier vehicle, the electric field components will generate static electricity. If the electrostatic discharge device (such as discharge needle, grounding copper bar) malfunctions, static electricity may accumulate to dangerous voltage, causing leakage or electric sparks.

4. The humid environment exacerbates the risk of electrical leakage

The humidity in the kitchen environment is high, and if the sealing of the equipment is insufficient, water vapor may seep into the internal circuits, leading to a decrease in insulation performance. Especially during the rainy season or for equipment that has not been thoroughly dried after cleaning, the probability of electrical leakage significantly increases.

2、 Professional troubleshooting steps for leakage problems

Step 1: Power off inspection

After discovering a leakage, immediately cut off the power supply to avoid the risk of electric shock. Use a multimeter or insulation resistance tester to measure the resistance between the equipment casing and the grounding wire. If the resistance is below 0.5 megohms, it indicates the presence of leakage.

Step 2: Conduct a regional investigation

Step 3: Grounding System Test

Use a grounding resistance tester to measure the resistance between the grounding wire and the ground. The national standard requires a grounding resistance of 4 ohms. If it exceeds the standard, a new grounding wire must be laid.

3、 Guanglan Purifier: The Core Advantage of Safe Design

In response to the issue of leakage, the Guanglan purifier incorporates multiple safety designs during the research and development phase:

• Power cord inspection: Observe whether the outer skin of the power cord is damaged, whether the plug is loose or burnt..
• Electric field component inspection: Check if the electric field plates are deformed, if the connecting wires are loose, and if the electrostatic discharge device is working properly..
• Control box inspection: Open the control box and check whether the internal wiring is aging, whether the components are burned or damp..

  4、 Solution to leakage problem

  1. Replace the aging circuit

  If the insulation layer of the circuit is found to be damaged during inspection, it is necessary to immediately replace the power cord that meets the standards and use waterproof connectors to fix the connection.

  2. Repair the grounding system

  Re lay the grounding wire to ensure that the grounding electrode is buried at a depth of 1.5 meters underground, and use a reducing agent to lower the grounding resistance. Regularly check if the grounding wire connection is secure.

  3. Clean up static electricity accumulation

  Regularly clean the electric field components and check whether the discharge needle is worn or blocked. Guanglan purifier is recommended to undergo professional maintenance every 3 months to ensure the normal operation of the static discharge device.

  4. Improve the usage environment

  Install the oil fume purifier in a dry and ventilated location to avoid direct contact with water sources. After cleaning the equipment, it needs to be thoroughly dried before being powered on for use.

  5、 How to prevent leakage problems?

  • Double layer insulation protection: The internal circuit uses high-temperature resistant and corrosion-resistant insulation materials, and the outer layer is equipped with protective sleeves to provide double protection against leakage..
  • Intelligent leakage protection device: Equipped with a leakage sensor, it automatically cuts off the power supply within 0.1 seconds when abnormal current is detected, avoiding electric shock accidents..
  • Moisture proof sealing structure: The equipment casing is designed with an IP55 protection level, effectively blocking the intrusion of water vapor and extending the service life of the circuit..
  • Professional Grounding Guidance: Guanglan Purifier provides detailed grounding installation guidelines to ensure that the grounding resistance meets the standards and eliminate leakage hazards from the source..
