What is the reason for frequent tripping in cold storage?
1. Overload. When overloaded, you can reduce the power load or stagger the power usage time of high-power equipment.
2. Leakage. Leakage is not easy to check. If there is no special equipment, you can only try one by one to see which equipment is prone to tripping. In addition, aging of the line will also cause tripping.
3. It will trip immediately when there is a short circuit.
4. The defrosting circuit is leaking electricity. Remove the leakage protection and try.
5. Control switch, use a multimeter to test the circuit of the cold storage. If there is no short circuit or leakage, it means that the instantaneous current is too large. Replace it and control the switch.
6. If it trips when the power is turned on, check the control box.
7. If the compressor trips at the moment of starting, check the internal fan and the external unit. The internal fan is easy to check, see if the fans inside are running, and the external unit.
8. Powered parts: cooling fan, compressor, solenoid valve, check them yourself.
There are many reasons for cold storage tripping. Here are some reasons for cold storage tripping:
1. First, observe whether the tripping is regular: If the cold storage trips regularly, check whether there is a problem with defrosting. It may be a leakage of the defrosting heating pipe or the water heating wire;
2. Whether the compressor trips after running for a while. If so, it may be high and low pressure protection. Check whether the refrigerant is lacking or other reasons;
3. Whether the compressor overload protection trips, check whether the pressure protection value is within the range, because the protection value in winter and summer will be adjusted inconsistently
4. It may also be that the company’s voltage is insufficient, and undervoltage causes the cold storage to trip. This requires professional cold storage maintenance workers to operate;
5. It may be that the relay in the electrical box has poor contact. You can tighten all the terminals in the electrical box.
6. Check whether there is leakage in the door frame heating wire and the cold storage light circuit of the cold storage;
7. It may also be that the wires of the cold storage are damaged.
