Complete switchgears КРУ are designed to:
The main functional units of КРУ have been tested in the very tough conditions of high dust and gas content, extreme temperature and humidity content – and have demonstrated the best parameters.
High-speed vacuum breaker, fault-tolerant control blocks and micro-controller systems are a guarantee of the reliability of the КРУ.
КРУ can be used not only as single devices, but as an integral part of the distribution point.
The basis of the КРУ diagram design is a micro-controller block of МКЗП connections, which performs about 30 different protection diagrams, tens of automatic control functions. That’s why you can realize any automatic control projects of the industrial current collectors with the help of КРУ.
The specific design of КРУ prevents the personnel from performing the actions which can result in dangerous situations. This is achieved by application of great number of electric, mechanical and electro-mechanical interlocking systems.
These interlocks allow to avoid the following:
In the distribution point there are some electric interlocking systems, preventing the supply of voltage to the earthed section of the busbar.
The КРУ-based distribution devices are the complete engineering products, providing the user with the widest TV and automatic control possibilities, realization of different dispatch systems, data transfer and archiving, as well as numerous functions of automatic control and relay protections.
The КРУ cabinets have the compact dimensions – they are rather tiny in comparison with the existing analogues. This advantage is the most important during designing of the large distribution device – it demands less space and maintenance of the cabinets is more comfortable. That is why КРУ are called-for at the industrial enterprises.
External appearance of the КРУ cabinets is thought over in all the details: it is easy-in-use, practical and informative. There are only required control and warning system elements at the door and the covers. They are located in such a manner that does not create the visual overload, boring the maintenance personnel. The КРУ cabinets are easy and comfortable to work with, that positively results in quality and production efficiency.
The distribution devices, mounted of КРУs, are located in detached, easily mounted modular buildings manufactured by EXC. The modular buildings have got their own heating and electricity supply systems; they can be equipped for the regular staying of the personnel-on-duty. When it is necessary, the distribution device can be shifted into another pace. You will need only several hours for the dismantling and subsequent assembling of the modular building.
