Industrial switchboard is a space where electrical equipment is installed. This switchboard is not necessarily metal and there are also non-metallic materials. As mentioned, there are various equipments inside the electrical panel, which are different according to the purpose for which the electrical panel is designed. To put it better, each of the equipment used in the electrical panel has a specific role and function, which are used for the same purpose in the electrical panel.
Types of Industrial Electricity
Metal Enclosed Panels
This category of industrial switchboards are closed metal enclosures in which there are many electrical equipments. The electrical equipment available in this type of switchboard are: switches, current transformers, voltage, busbars, measuring devices, etc. All these equipments are installed inside the switchboard. Metal Enclosed switchboards are divided into two categories, which we will explain below.
Metal Clad panels These types of electrical panels are designed in such a way that the compartments are separated in their interior. Separation of compartments has an advantage, and that is, if an error occurs in one of the compartments, it remains in the same compartment and its error is not transferred to the other compartment. This is very important for the electrical panel because in this way other compartments are protected from damage in the event of an accident.
Metal Clad panels include four parts: Busbar compartment Cable compartment Key compartment Control compartment
Compartment Type Panels
In this type of electrical panels, unlike the previous panels that we explained about them, its inner compartment is not divided into smaller parts.
Equipment
⦁ introduction of fuses
Fuses are among the most important and key equipment inside the industrial switchboards, which protect the circuit against short circuits and overload. Electrical panels also have a fuse, whose important task is to prevent the increase in the amount of electric current entering the circuit.
⦁ Introducing the miniature key
The miniature switch or MCB is also considered as another widely used and important equipment in the industrial switchboard, which can automatically and under certain conditions such as overload (passage of illegal current) or short circuit, completely cut off the current in the electrical circuit in the network. slow down If we want to compare fuses and miniature switches, we must say that miniature switches are more reliable and more sensitive than fuses.
⦁ Introduction of bimetal
Another suitable and excellent equipment for industrial switchboards are bimetals, by means of which you can easily convert temperature changes into mechanical displacement. Regarding the main and important task of non-metals in industrial switchboards, we can mention the protection of the three-phase motor against overload in low voltage applications.
⦁ Introduction of thermal key
In the industrial switchboard, the thermal switch or MPCB is actually a type of electrical component that protects the electric motor against external factors and conditions, among the important and main tasks of these switches.
⦁ Introducing the power cut-off switch
Circuit breakers are widely used in industrial switchboards, that's why they can be categorized as roller, micro switch, selector, etc. based on the type of activity they have.
Introducing the compact key Compact switches or MCCB are other electrical protection devices that are considered among industrial electrical equipment. Compact switches are used in a wide range of frequencies and voltages of 50 and 60 Hz. The main difference between compact switches and miniature switches is that compact switches are much larger than miniature switches and can have a rated current of up to **** amps, and these switches are also adjustable.
⦁ Introducing the contactor The task of connecting and disconnecting the current to the electric motor in the industrial switchboard is the responsibility of the contactor. Keep in mind that in case of problems such as voltage drop, phase shift, three-phase voltage asymmetry, and also one of the phases is disconnected, the contactor will not allow the motor to start.
