What is overload protection?
Overload protection is most often used with reference to electrical systems. It is a safety mechanism to prevent or minimize damage that can occur from electrical failures. In general, if the problem occurs in the electrical circuit, the electricity current will be automatically cut off by the protective system. In addition to electrical systems, another type of overload, sometimes called thermal protection, can be used to protect motor systems and similar devices. This is due to overload protection. Most electrical systems are designed with a secure security or overload mechanism that it takes when something has gone wrong in the circuits and automatically cuts off electricity to avoid occurring fire or other problems.
The electrical circuit is designed to carry a certain amount of energy or voltage. The energy flow, called the current, should travel from one point to the other unlimited. If this current is interrupted, it causes what is runningThey are known as short -circuit . If the electrical system is designed correctly, the overload protection will begin to stop the energy flow until the interrupt source is removed.
electric current interruption may occur from the inside of the circuit itself. For example, if a device such as a toaster overheats or failures, it can send an excessive energy increase through the perimeter, exceeding those designed to carry. This increase will be interpreted as an interruption of current and often triggers overload protection. External sources, such as damage that occurs due to a tree -falling tree branch, can also disrupt electric current and activate the protection of the circuit overload.
Depending on where the problem occurs, the power supply can be interrupted into the insulated section or the entire electrical system. For example, when using an example of a residential electrical system if the person's VL dryerAsy can cause a breaker tripping, affecting only the output into which the hair dryer was connected. On the other hand, the electrical increase caused by a lightning strike can cause the main circuit breaker in the house to stumble and cut off the energy throughout the house. Similarly, if the tree falls on the outer electrical line, electricity could be interrupted throughout the neighborhood due to the location of the interruption.
Another type of overload protection, often called thermal overload protection, is built into some mechanical devices such as engines or engines. In this case, the protection is designed to prevent damage to the engine or other similar device caused by overheating. Overloading relays to the engine, engine or other device is designed to respond to excessive internal temperatures and automatically turn off the power supply in the unit to prevent permanent damage and allow forced cooling periods.
