MDB. Main Distribution Board

The main distribution board (MDB) was created for receiving and further redistribution, monitoring and accounting of electricity by consumers. As additional functions, MDB can be used to protect lines from short circuits, overload and current leakage.

The Group of companies "Teplovye Sistemy Llc" sets the development of Russian production as one of its most important tasks. The company already has its own production facilities of more than 600 m2 and continues to invest in production. A wide range of products both in a universal version and on demand allows to ensure a short production time: from 20 to 45 days, depending on the complexity of the equipment. Using Schneider Electric licensed components as working equipment, we improve the reliability and service life of products in full compliance with world quality standards.

MDB design

MDB includes:

• Input panel for arrangement of automation for power reception

  Sectional panel with circuit breaker for connection of several sections from one input

  Backup power supply device

  Monitoring devices

Visually MDBs can be very different from each other since they are produced for different numbers of inputs and outputs. More often though the main distribution boards are made with two inputs and outputs. Power is supplied from transformers, and output is made through a sectional panel. One of the important advantages of the main distribution board is the ability to disassemble all sections.

New modern low-voltage equipment manufactured by "Teplovye Sistemy Llc" is designed specifically to support production and business development. It is highly effective for several reasons:

• Quality and ease of use, thanks to the usage of components made by the world-class manufacturers: ABB, Schneider Electric, KEAZ:

• Always ready for sale, because is always available.

• Production according to individual projects is possible.
• High reliability at affordable prices.

When choosing a type of MDB, it is important to pay attention to its characteristics. The following indicators are decisive:

• Grounding system.

  Degree of protection as per GOST.

• Rated system voltage.
  

Also, in the design of the MDB, the following devices are used: metering devices, control devices, instrumentation, load switches. "Teplovye Sistemy Llc" has developed and implemented in its equipment the ability to connect a remote control system using proprietary software and plug-in touch monitors.

Installation process

The product installation process is simple. But here the sequence of operations performed is very important. For example, first it is necessary to install circuit breakers on the panel, adjust the placement of copper buses. Power supply of MDB sections is carried out using mutually redundant lines. Plastrons made of non-combustible material are used to protect against electric current damage.

During installation, rheostats and regulators, fuses and signaling devices, relays and circuit breakers are also installed in the main distribution board.
