The refrigerator is a must-have household item in our home, and in order to protect the refrigerator, the refrigerator protector will appear. The following small series will introduce the principle and use of the refrigerator protector .
How the refrigerator protector works
In the process of running the refrigerator, it is inevitable that the voltage will be unstable. However, in this case, the operation of the refrigerator will be hindered, causing damage to the internal components of the refrigerator, and the refrigerator protector can perfectly solve this problem. one question. The refrigerator protector uses a high-gain four operational amplifier integrated circuit as a comparison amplifier, and uses a bidirectional thyristor as an automatic switch in the power supply loop, and is equipped with a power supply indicator. The protector circuit has a simple structure, good reliability, and volume. Small, light weight, low cost, low power consumption, and various protection functions such as undervoltage, overvoltage, overcurrent, and delay start. A power socket type refrigerator protector comprising a circuit of buck, rectification, voltage stabilization, sampling, delay, etc., characterized in that a high gain four operational amplifier integrated circuit is used in the protector circuit as a comparator, A two-way thyristor is used as a power supply circuit automatic switch, and has an overcurrent protection relay and a power on/off indicator. The refrigerator protector is a socket type refrigerator protector, which mainly uses two-way controllable silicon as a power supply circuit as an automatic switch, and is equipped with a power supply indicator. The refrigerator protector has a simple design and a simple structure. At the same time, it has the characteristics of small size, light weight and low cost. Its largest function is the function of various refrigerators with undervoltage, overcurrent, overvoltage and delay start. Effectively guarantees the working environment of the refrigerator, reduces the damage of the voltage to the compressor of the refrigerator, and prolongs the service life of the refrigerator.
Three characteristics of the refrigerator protector
1. Energy saving. The refrigerator protector intelligently controls the time of power outages and power supplies to regulate the downtime and start-up time of the refrigerator and other appliances.
2. The time adjustment range of the refrigerator protector is: 5 to 140 minutes for shutdown and 5 to 140 minutes for startup.
3. Delay protection: The delay protection of the refrigerator protector protects the compressor of the refrigerator by means of power-on, which effectively reduces the damage caused by the power supply to the compressor.
The above is the working principle of the refrigerator protector and its three characteristics, I hope you can more clearly understand the refrigerator protector through this article, and better use it in real life.
