SN RSL-I switchgears
SN RSL-I switchgear is the so-called smart switchgear.
It has been designed as an element of Smart Grid and manufactured as part of the Innotech ID 182726 programme. It was a special type of order, developed based on an agreement concluded between the National Centre for Research and Development (NCRD) and Elektromontaż-Lublin Sp. z o.o. This is mainly the achievement of authors of this very type of a switchgear, developed by the industrial and scientific consortium. It consisted of such entities as the abovementioned Elektromontaż-Lublin Sp. z o.o. as the consortium leader, plus Transformex Sp. z o.o. from Warsaw, Tele and Radio Research Institute and Lodz University of Technology. The resulting product is fascinating through its innovativeness and perfect operation.
Advantages of SN RSL-I switchgears
The basic advantages of the smart SN RSL-I switchgear include full local and remote controllability, which offers maximum comfort and safety, as well as auto-diagnostics. Another advantage is of course the affiliation with the Smart Grid and operating safety. This is a highly reliable switchgear and a model that requires minimum scope of operating activities from the personnel. The switchgear operates at the rated voltage of 17.5 kV and 24 kV.SN RSL-I switchgears – a modern solution
So what are the novelties when it comes to the solutions applied in the SN RSL-I switchgear? Above all, this is a brand new and revolutionary electrical power measurement system, which offers additional opportunities in every field of its operation. What does it consist in? This is a system that applies an innovative solution of hybrid current and voltage transformers with electronic elements. How can we benefit from this solution? It allows us to eliminate a measuring cell and a double number of transformers, mainly used for protection and diagnostic purposes. What is also new is the application of a smart bay controller – ISP 70, adapted to work with the Smart Grid system and an extended diagnostic mechanism related to ISP 70 modules (power quality analyser, remote diagnostics unit, criterial recorder unit and communications unit in the IEC 61850 standard). It all allows notifying the user of occurring events and measuring the temperature of busbar contacts and air humidity in the cell.MV RSL-1,6 switchgears
A SN RSL transformer switchgear, variant 1 and 6, is a top quality product which allows uninterrupted and reliable electrical connection and operating efficiency. It is failure-free owing to traditional methods and special technological solutions applied in the manufacturing process. SN switchgears in variant 1 and 6 were manufactured with a bay width of 650 millimetres and based on direct drives. They operate in the so-called rear arrangement, also referred to as a reverse arrangement, with appropriately applied cut-off switches with earthing switches. In this aspect both variants differ from each other, as the first one includes
ABB cut-off switches of the OR type, while the sixth variant uses ZWAE cut-off switches of the OM type.
The operation of this type of a switchgear is based on inserting a special removable lever into the drive socket. This triggers the activation of the cut-off switch (activate or deactivate positions). A drive socket is located directly on the cut-off switch shaft, therefore it is convenient to control and locate. After all, a drive lever for earthing blades, necessary for proper and efficient operation of the MV switchgear of the RSL type, has a similar position. What are the benefits of such a drive? Above all, it allows minimising the width of a cell, thus it increases operating performance and convenience of using these variants of the MV switchgear. Additionally, for economic and security reasons, a mechanical interlock of cut-off switches with earthing blades has been applied. This factory-installed function prevents activation of the cut-off switch when the earthing switch is closed and closing of the earthing switch when the cut-off switch is activated.
RSL switchgear – structure
High quality technical manufacturing of the entire switchgear has been guaranteed. The sole busbar system is made of an insulated copper rod, while partitions between the cells are made of insulation plates. The MV RSL-1 and RSL-6 switchgear is not arc-proof; it is offered only in the “0” standard version. Rated voltage at which the switchgear in these variants operates is, obviously, 17.5 kV and 24 kV. We are dealing here with 3 phases at a rated frequency of 50 Hz. When it comes to the protection rating, we are dealing with IP2XD and IP4X values, therefore these are high quality products that safeguard the security of the entire system. MV switchgears of the RSL-1 and RSL-6 type offered by us meet the European standards PN-EN 62271-200:2012 and PN-EN 6227-1:2009. Additionally, the sixth variant comes with the Compliance Certificate no. 059/2014 issued by the Institute of Power Engineering in Warsaw.
