The aging rack of the aging cabinet is divided into product area and load area, separated by an electric wooden board in the middle. Test products are placed in the product area, and the load for testing products is placed in the load area. The load and its connecting wires are provided by the customer themselves; The load area is not controlled by temperature, and an exhaust fan is installed to exhaust the heat generated by the product due to load operation, so as to maintain it at room temperature.

Protection method for aging cabinet

When operating stably or exceeding the set temperature (≥ 2 ℃), the cooling air duct in the product area is opened to maintain a constant temperature inside the product area

2. Over temperature protector: When the circulating fan malfunctions or the heater loses control, cut off the heating system and product power supply

3. Air incinerator protector: When the temperature of the heating tube gauge rises to 100 ℃, cut off the power supply of the heater

4. Ceramic wire: Heating tube overcurrent protection

5. Leakage switch: System overcurrent and leakage protection

6. Indicator light and buzzer sound and light alarm device: When protecting against overheating and motor overcurrent, the indicator light and buzzer will sound an alarm

7. If the exhaust fan in the load area malfunctions, cut off the power supply of the product

8. The system is equipped with smoke alarm devices, with 2 in the product area and 2 in the load area. When the smoke alarm is triggered, the system power is cut off

9. Overload protection for exhaust fans and circulating fans.

10. Power supply under phase protection to prevent reverse rotation of the circulating motor caused by changes in the phase sequence of the power grid

Aging cabinet protection system

1. Fan overheat protection

2. Overall equipment under phase/reverse phase protection

3. Overload protection of refrigeration system

4. Refrigeration system overpressure protection

5. Overall equipment timing

6. Water pump overheat, overcurrent protection

7. Other protections include leakage, water shortage, operation indication, and automatic shutdown after fault alarm.
