A short circuit is a serious accident that can lead to dangerous consequences. From the point of view of physics, a short circuit is a consequence of the contact of several points of an electrical circuit, which have different potential values that were not originally foreseen. A distinction is made between single-phase, two-phase and three-phase closures. If you buy high quality electrical products, you can prevent short circuits.
Varieties of devices for protecting electrical appliances from emergency network modes
One of the simplest, but at the same time quite effective devices for protection against short circuits, is a fuse. Initially, only this method of preventing an accident was used for domestic purposes. Due to its convenience, simplicity and low cost, the device is used even now. It quickly responds to an emergency mode that has arisen and effectively protects semiconductor devices. The disadvantage of the fuse is that after operation it is required to replace it with a new device or repair the existing one. Surely everyone knows what a cork is. This was the most common fuse in the past.
More advanced fuses are automatic steam plugs. They differ in the following characteristics:
- suitable for multiple use;
- can protect not only from short circuits, but also from network overloads.
A convenient way to protect against short circuits is a circuit breaker, which prevents accidents by timely shutting down the system. There are instantaneous releases, the principle of which is electromagnetic. There are also time-delayed releases. Both of these devices operate on the same principle.
How to protect an apartment from a short circuit?
A short circuit is a very terrible and dangerous accident, so protection against it must be thought out in advance. Special machines installed in shields on each staircase of apartment buildings will help prevent short circuits. If possible, it is recommended to install a personal shield. This will allow you to achieve higher protection for your electrical appliances. You must always remember about safety and buy high-quality electrical goods in order to prevent a short circuit.
