As an important part of electrical equipment, overload protector has important application value in modern life, aiming to protect electrical equipment from problems such as circuit overload. This article will introduce the working principle, functions and application scenarios of overload protector.

working principle

The overload protector mainly detects the current in the circuit through the current sensor. Once the current in the circuit exceeds the designed working current range, the overload protector will automatically cut off the circuit, thereby protecting electrical equipment and personal safety.

Function

1. Temperature protection: When electrical equipment or lines are overloaded by overcurrent, the overload protector system will immediately interrupt the power supply and stop current transmission to protect electrical equipment from damage and reduce maintenance costs and time costs caused by electrical equipment repairs.

2. Electrical protection: The overload protector can detect the magnitude of the current in the circuit. Once the set current is exceeded, the system will automatically cut off the power source to avoid electrical failure and damage caused by circuit overload. At the same time, it can also protect the safety of the line and prevent the occurrence of accidents such as fire.

3. Personal safety: The overload protector can avoid personal injury. When the circuit fails, it will immediately cut off the power supply to prevent people from being shocked.

Application Scenario

1. Household applications: overload protectors are usually used in the protection of household electrical equipment, such as high-voltage electrical appliances, lighting systems, TVs, computers, microwave ovens, etc.

2. Industrial applications: In the industrial field, overload protectors are often used to protect various electrical equipment, such as motors, generators, transformers, etc., and are also used in various production lines and machinery to protect the safety of electrical equipment and workers.

3. Application in public places: overload protector is also often used in power system protection in public places, such as shopping malls, schools, public computer rooms, etc.

In short, overload protector has become an indispensable part of electrical equipment in modern life. Its main function is to protect electrical equipment and personal safety by monitoring the current in the circuit and automatically cutting off the circuit. The application scenarios cover households, industries and public places and many other fields.
