Modern and reliable power supply and automation solutions
Switchgears form the basis of power distribution circuits for household and industrial power and lighting installations. Distribution cabinets, switchboards and items are delivered pre-assembled or assembled to order according to standard and individual schemes.
What is the switchboard?
A switchboard, point or cabinet is one of the varieties of a low-voltage complete device designed for receiving, distributing and metering power supply, used in single- and three-phase current systems under voltage up to 1 kV. In addition, the electricity distribution point protects the network from over-design loads and short circuits, the device is also used for rare switching on and off of the lines of group electrical circuits (up to 6 cycles), starting asynchronous motors and protection against electrical injuries.
Contents of the switchboard
The switchgear is a metal or plastic box with a door, which contains switching, protective and measuring devices. The installation method depends on the type of device: switchboards are equipped with mounting panels, cabinets – with modular housings. The complete set of switchgears is limited to devices necessary for the distribution of currents within one room, floor or functional area; the minimum set of equipment includes:
- main switch-disconnector;
- residual current device;
- buses, terminals and other switching elements;
- energy consumption meter;
- protective and control equipment;
- elements of low-current networks (optional).
The switchgear is connected to external outgoing circuits; one of them is used for power supply; to protect against unauthorized access, the door is locked with a lock, and the wiring diagram and contacts are closed with a metal screen, which is attached to the panel with clamps. The shell of the cabinet is occupied by a chassis frame with circuit breakers; incoming and outgoing power lines are connected to the zero bus; in some cases, isolated neutral is established.
The design of distribution points varies depending on the scale and functions of the power equipment; device assignments are displayed in the series nomenclature. Let’s briefly consider the five main types of distribution points on which all known modifications and special solutions are based:
- main distribution boards – carry out the main distribution of power supply in low voltage systems;
- input and input-distribution devices – carry out input, distribution and metering of electricity in the room;
- distribution points – serve small-sized premises and separated areas of premises
- metering and distribution boards – assembled on a DIN rail using modular equipment in order to distribute and meter energy to end users.
For the correct functioning of all types of switchgears, a professional calculation of equipment and strict adherence to installation techniques are required. LLC “AVR PLUS” carries out design and installation of switchboards; our experts will help you choose the right equipment and optimize the operation of the power grid.
Manufacturing of points, cabinets and power distribution boards
Today, distribution points of 380/220 V are common with the use of a switch-disconnector at the input and fuses of the PN2 type (more often) and PR-2 (less often) as protective devices for both single and three-phase lines. This is unreliable and troublesome in actual use. Often, these assemblies are installed in administrative offices, corridors and other places that are accessible not only to electrical personnel. There are usually no guards (panels) at such distribution points, and this is potentially dangerous.
Structural solutions from “AVR PLUS”
The current solution, today, is the modernization of the switch cabinet with the replacement of the main switch with a modern automatic machine or switch (even with a visible break in the contacts), and voltage lines – with modular circuit breakers, while the housing of the enclosure with busbars can be left without changes; or a complete replacement of the enclosure with a new one, more compact and aesthetically pleasing with reliable protection equipment. The availability of accessories for connecting electrical elements and their safe operation allows you to get a compact panel at the output of the same power, completely suitable for use by non-electrical personnel (although in the conditions of a workplace, at least the initial groups must have an electrical safety permit for at least the initial groups). p>
Modular switchboards are widely used as final distribution switchboards, for large units a wide selection of enclosures made of different materials is presented, which will satisfy even the most demanding designer in new and refurbished facilities. The specialists of our company work with all types of switchgear equipment and will be happy to help you in its selection, both from a technical and aesthetic point of view.
