What is a powerboard?
What is the electrical panel and what components and parts does it consist of and what models and options does it have? All these questions are among the most common questions that newcomers to the field of electrical industry ask the experts in this field and look for an understandable answer. In fact, it can be said that the electrical panel is a set of mechanical and electrical parts of control, measurement, protection and adjustment equipment, sometimes embedded It is in a metal box that is used to control, power and distribute electrical energy in the electrical industry and is used to protect the users of the equipment.
In fact, electrical panels protect all equipment such as on/off switches, control knobs, display tools, etc. against environmental factors and protect users from electric shock.
Types of electrical panels
In terms of voltage level, the types of switchboards are divided into two categories: medium voltage switchboard (MV) and low voltage switchboard (LV). and voltage, control equipment, etc., and it is mostly used for industrial purposes in two types, fixed and sliding.
On the other hand, low pressure switchboards are used in transformer stations and when high voltage current is converted to low pressure and in order to electrify buildings with equipment suitable for such voltage, such as control, measurement, protection equipment, etc. Weak pressure panels are designed based on standard sizes and depending on the installation location, from materials such as iron, cast iron, etc., in standing, wall, in-use, and in-use models.
Most of the signs in the engine room and open spaces are assigned to the standing type and other examples are used for covered spaces. The installation of panel devices as well as the wiring inside the electrical panel should be done in such a way that the repair, separation and replacement of wearable parts can be done easily.
Most of the time, mosaic system is preferred over other methods due to ease of access. Of course, the weak pressure panels are divided into the following categories based on the location and location, as well as the power source and its role in the power control and distribution system:
Low pressure main board
Semi-main panels of weak pressure
Facilities and equipment sub-panels
Lighting sub-panel
Structure of electrical panels
The structure of the electrical panel is generally divided into two categories: COMPARTMENT TYPE and METAL CLAD. In COMPARTMENT TYPE, the available compartments are continuous and not separated from each other, hence each part has a mutual effect on the other part.
But in the METAL CLAD sample, the chambers are installed separately from each other, so the error of one cell is not transferred to another, and thus the adjacent chambers are protected from damage. The different parts in METAL CLAD are divided into four parts: the compartment with the cable, the cable head compartment, the control compartment including the measuring, protection, control equipment and finally the key compartment.
The most important components of the powerboard
The most important components of the electrical panel according to the needs of employers include a fuse to protect the circuit against short circuit and overload, a miniature switch with the possibility of not burning, a metal switch with the ability to cut off the circuit in case of a sudden increase in temperature, and to protect three-phase motors. . Also, the thermal switch with the function of protecting electric motors against overload, the current leakage switch with the function of protecting the user from electrocution, the conductor with a function similar to a relay are other essential parts in all types of electrical panels.
Of course, a push button or an electric switch to manually disconnect and connect the current, a signal light to show the on and off status, a warning light with the mission of remote alarm, a timer to send the signal timing, and finally the terminal, micro switch, cable duct and... are also among the other equipment available in electrical panels, which are available in most of them.
What is a Warning Panel?
In order to eliminate the technical problems that cause the lack of The electrical panel works properly, before mounting the electrical plan designed by the contractor, they use a table called wiring to test the defects and minimize the defects. Thus, what are the benefits of using electrical panel wiring?
To answer this question, we can say: minimizing mistakes, improving the speed of electrical work assembly, applying a comprehensive method with the lowest percentage of errors, having a table for measurement and troubleshooting. And finally, he knew the possibility of developing the electrification system in the future.
What is a power panel cell?
The switchboard cell is made of wooden frame or skeleton and special columns and is made with the help of bolts and nuts or CO2 welding with a certain degree of IP protection according to the client's request from galvanized sheets with a structure according to two models of adhesive foam and Injection foam is designed.
To explain the applications of switchboard cell, what is it? It can be said that the use in power, distribution and control systems is the best place to use these cells because of their strong skeleton and no change in their structure.
Specifications of the power panel
Specifications of electrical panels, including low pressure and high pressure panels under IEC standard, have 8 separate sections that examine each electrical panel from different aspects. We will get to know you better:
Rated voltage (UR)
Rated Insolation Level
Rated Frequency
Rated Normal Current
Rated Short Time Withstand Current of electrical panel
Rated Peak Withstand Current
Nominal short circuit time
Nominal voltage of auxiliary equipment of electrical panel (Auxiliary Circuits Voltage)
What is the MDP powerboard?
And what is its role after the main electricity cable enters the building? Because they consider MDP as one of the main types of electrical panels, the transmission of electrical energy to all building units and common areas is considered one of the main tasks of this panel, and it is considered to have three main parts: the electricity input part, the meter part, and the service part.
