electrical panel

The switchboard is a compartment for installing and wiring electrical or electronic equipment, where switches, control and protection parts, and display devices (voltage, current, frequency, power, cosine phi, etc.) are installed on it. Also, electrical panels are used to prevent electric shock to equipment users and protect equipment against environmental factors.

Types of electrical panels in different industries

Distribution Panels: These panels are usually used to distribute electricity in buildings and industrial units. They include switches, protection circuits and equipment needed to distribute electricity to various consumers.
Control Panels: These panels are used to control and manage devices and machines in various industries.
Industrial Automation Panels: These panels are used for the automation of industrial processes and systems. These types of boards include programmable circuits (PLC), sensors, displays and other advanced control equipment.
Protection and Safety Panels: These panels are used to protect electrical systems and equipment in industries.
Power Distribution Panels: These panels are used for high power distribution in large industries. This type of powerful switchboard includes items such as transformers, power switches, protection circuits and other power distribution equipment.

Also, in some special industries such as oil and gas industries, chemical industries and processing industries, there are also special electrical panels that distribute electricity and control special processes in these industries.

The main components of the electrical panel

Switches and circuit breakers: for disconnecting and connecting electrical current as well as protection against overload and short circuit.

Relays: devices for controlling and commanding electrical equipment.

Fuses: to protect circuits against excess currents.

Voltmeter and ammeter: to measure and display voltage and current.

Contactors and timers: for automatic control of electrical equipment.

Switchboard operation

Power circuits

All connections that transfer energy from the network to the consumer are called power circuits, such as a three-phase contactor that delivers three-phase current to the consumer.

Command circuits

In fact, the part of the circuit that plays a role in connecting and disconnecting the contactor and controlling the work of the consumers is called the command circuit. This circuit has nothing to do with the power circuit and it stimulates the contactor coil so that the contactor is connected or disconnected. .

current consuming equipment (consumers)

There are equipments that are made to convert electrical energy into other forms of energy such as light, heat, movement, etc.

Types of keys used in electrical panels

Switches used in switchboards are devices that are used to perform one or more of the following purposes in electrical circuits:

Control
protection
connect and disconnect
Separation of different parts from each other

Fuse selection

The choice of fuse is based on the type of circuit protection (overload, short circuit) and considering the type of load (fast or fast-acting fuse, delayed or slow-acting fuse) and by referring to the characteristic curves of the fuse performance (time current curve). If several fuses are used in a row to provide local protection, it is better to select the upstream fuse with a factor of 1.6 times the downstream fuse in order to prevent untimely operation of the fuse as much as possible. Circuit protection devices are selected according to the adjusted permissible current (after applying different coefficients to the required current, such as the synchronism coefficient).

The standard of the internal components of the electrical panel

The equipment inside the panel must be designed, manufactured and tested according to the standards of the table below or one of the similar valid international standards.

Electrical panel in Yazd

The manufacture of electrical panels in Yazd in the form of professional design and professional assembly of all types of standing and wall panels, which includes all types of industrial panels such as main – Ats – PLC – dpo electrical panels, etc. and guillotine etc. are done.

The steps of making an electrical panel

Assembling electrical panel in Yazd electrical panel factory

In the Yazd switchboard factory, which is the most sensitive issue in the construction of the switchboard in Yazd, the assembly stage of the switchboard must be done well because the staff are trained to maintain the quality of the switchboard, including beauty and compliance with safety issues.

During the assembly stage, all the electrical equipment is placed on the assembly plate and in the designated place by the bridges made in the metal part of the panel, and after the ducting equipment is installed, it is suitable for the considered space and the volume of the wires. It is supposed to pass through the channels and be installed. In the next step, it is time to wire the panel.

The wiring of the panel should be selected according to the desired part for which the amperage is intended. For example, for the 63 amp automatic switch, grade 10 wire is used. All wiring with the desired wire number as It is done exactly as indicated in the map.

At the end, after the wiring is finished, all the connections and technical checks and tests are done and the panel is prepared for the packaging stage.

Industrial switchboard in Yazd

The construction of electrical panels in Yazd includes ready-made or ordered panels, and industries, factories, and mass production companies in Yazd present their panels in the form of a project to the panel-making companies, and contracts with them are closed on the specified date. Signs are installed and delivered.
