Supermarket refrigerators are one of the very common household appliances in our daily lives. In order to better enable us to use supermarket refrigerators in our daily lives, we need to carry out maintenance. Next, let us teach you the methods of maintaining supermarket refrigerators.

First: Voltage loss protection

The zero voltage protection of supermarket refrigerators is controlled by a knife switch to switch on and off the circuit of the motor. When the power supply suddenly disconnects and the motor stops, if the power supply is suddenly restored at this time, the motor will resume starting. However, if this situation is serious, it may cause production and personal accidents.

Therefore, if there is a self-locking link in the control circuit of the supermarket freezer, there will be corresponding voltage loss protection. When the power supply suddenly loses power and suddenly resumes, the button should be restarted to start the motor.

Second: Short circuit protection

In order to ensure the safety of all aspects of electrical equipment, when any electrical appliance in the supermarket freezer experiences a short circuit, the circuit itself must have protective capacity to reduce damage to other electrical appliances. Short circuit protection consists of a fuse and an automatic switch

The two are jointly composed.

Third: Overload protection, i.e. thermal protection

The rated current allowed for the household appliance itself is generally the rated current of the electric motor. If the load on the motor is too large or due to other electrical faults, the current passing through the motor exceeds its rated current, the main motor will be in load operation. Although the fuse will not blow for a while, the motor may burn out over time.
