Industrial switchboard

Industrial electrical panels are in the form of compartments inside which parts and Electrical control equipment is installed. This enclosure protects its equipment and parts from environmental factors and prevents people from being electrocuted. Usually, these panels are made of different materials such as metal, polycarbonate and composite, and their internal equipment is different depending on the use of the electrical panel.

Inside the enclosure of the industrial switchboard, electrical or electronic equipment such as switches, knobs and displays are arranged in a row are insulated; Therefore, the operator can easily control, repair and replace them.

1. Metal Enclosed Panels: These panels have a metal enclosure inside which all electrical equipment including switches, current and voltage transformers, measuring devices, busbars are installed. Metal Enclosed boards are divided into two categories: Metal Clad boards and Compartment Type boards. 2. Metal Clad switchboards: In the Metal Clad industrial switchboard, there are different compartments separately so that when an error occurs in one compartment, the other compartments are not damaged and do not suffer from errors. 3. Compartment Type Panels: These panels are another type of Metal Enclose switchboards, unlike Metal Clad industrial switchboards, the compartments are connected and not separated from each other. 4. Withdrawable switchboards: Industrial switchboards are usually used to control motors and have greater safety and easier service. 5. Rack electrical panel: The shape of the rack electrical panel is like a shelf, and it is the place to install all kinds of control, telecommunication, measurement and electronic enclosures on this electrical panel. 6. Swing switchboard: This industrial switchboard model is a rack type switchboard and has a high price due to its movable glass door. In the Swing switchboard behind the equipment, it is visible and easy to access.

In all types of industrial switchboards, low pressure switchboards and home switchboards, the installation location is very important and has a great impact on the way the switchboard is made. According to the place of installation, industrial and household switchboards are divided into two categories, internal and external. 1. Indoor: The place of installation of the indoor type of electrical panel in a closed environment includes inside the hall, shed, workshop. 2. Outdoor: Outdoor electrical panels are designed and built in such a way that they can be installed in the open environment.

Electrical panels are classified as follows depending on their voltage level. HV switchboard or high voltage switchboard: voltage between 36,000 and 40,000 volts, maintenance of this group of switchboards is very important and SF6 gas is used for their maintenance (due to lack of reactivity). MV or medium pressure switchboard: the voltage consumption is between 1,000 to 36,000 volts, which is divided into different types such as subsurface medium pressure industrial switchboard, metal includes, padded, sliding, gas insulated, metal cold, etc. LV switchboard or weak pressure: consumption voltage less than 1000 volts, which is divided into different categories based on the type of building, such as rack, wall, table and standing industrial switchboards.

The voltage level of the medium pressure switchboard is between 1000 and 36000 volts. Medium pressure switchboards are assembled as multi-cells, and the components and equipment inside it include the body, switch or generator, medium pressure contactor, ground isolating switches, busbar, relay, measuring equipment, voltage and current transformer, and control equipment. The equipment used in the medium pressure switchboard must be made of quality and standard materials to minimize the possibility of any accident. Medium pressure switchboards are produced in two categories: fixed medium pressure switchboard (Fix) Withdrawable medium pressure switchboard

According to the appropriate pressure and voltage, the main application of this model is in various types of electrical panels in large industries and factories, which compared to Weak types of fizos have more pressure and therefore are used in a wide range of electrical systems and equipment related to them.

In this group of types of building electrical panels, there are various equipments such as earth disconnector switches, power switches, load disconnect switch, voltage measuring transformers and Current, medium pressure contactors and.. are used.

Weak voltage switchboards are produced at a voltage level of less than 1000 volts. This switchboard includes weak pressure disconnecting and connecting equipment, control equipment, measurement, protection, indicator, regulator; All these devices are connected to each other by means of connectors. The nominal voltage of low pressure panels is up to 690 volts and the service voltage is up to 400 volts. The size, design and material of these signs are determined based on the installation location and the type of application; Usually, the weak pressure panel is made of cast iron and iron and is built in, facing, wall, standing and covered. Note that the equipment and wiring inside the electrical panel must be accessible so that it can be repaired and inspected easily.

The main use of this board is to protect electrical circuits and the equipment used in them, which are used in all kinds of commercial and industrial facilities, transformers, power supply circuits And.. is used. This panel is also used in refineries, converter stations, power stations, etc.

To make a low pressure switchboard, which is one of the most widely used types of switchboards, various equipments including transformers, contactors, double bushings, Micro switch, limit switch, single-phase and three-phase bimetal, transformer, automatic switches, all kinds of cables, etc. are used.
