From the beginning of this year of energy of branch of OAO «Moscow incorporated elektrosetevaya company» – East electric networks – executed near 60% annual program on replacement on the feed-in centers of measurings transformers of tension (TN) of 110 kv. A plan foresees 2009 years replacement of a 91 phase of TN. To date the specialists of enterprise by an economic method replaced 54 phases on substations «Paradises», «Likino», «Orbit», «Comb», «Selfheal», «Misheron’», «Twins», «Botino», «Grodok» and «Lilac». For
improvements of functioning of substations, increases of pozharobezopasnosti, and also declines of expenses on exploitation of feed-in centers at replacement of producing the resource of old measurings transformers of tension new TN is everywhere used with oily
by an isolation. They are hi-tech, pressurized, vzryvobezopasnye, practically neobsluzhivaemye during all term of exploitation, which makes no less than 30 years.Measurings transformers of tension are to one of important links of all complex
equipment of substation. They serve for transformation of high tension to low, standard values, which is used for the feed of devices of defence and automation, and also facilities of account and measuring. They the same as and transformers of current, the instrumentation insulate
devices and devices of protecting from high tension, providing safety of their service. Such works were conducted the other day on substation 110/10 kv «Selfheal». Substation is major in the power supply of city Selfheal. Feed-in center by power
40 Mvt provides electric power the kommunal’no-bytovuyu, industrial infrastructure of naukograda: more than 25 thousand of population, large scientific institutes, factories (Experimental factory of Russian Academy of sciences, factory «Ostalko») and other Old TN, set on
substations,
(services of substations, services of relay defence and automation) here set new analogues – measurings transformers of tension of the European production of firm TRENCH. Works are very important, because this equipment is the necessary element of measuring chains,
account of electric power, chains of relay defence. The cost of works on replacement of six phases made about two million roubles», – told to the portal EnergyLand.info deputy of main engineer on the high-voltage networks of branch Yuri Stukalin. to the words of chief Distant
groups of substations of the East electric systems of Vyacheslava Peskova, in a next 2010-om year substation «Selfheal» will be shown out in complex major repairs. But work on modernization of feed-in center actively conducted already now. Besides replacement of Tn-ov in a list
basic works replacement of inputs will enter on oily switches. Also inputs on power transformers will be transferable on new – with a hard isolation. Old porcelain insulators will be substituted by hi-tech and reliable polymeric. To all vysheperechislennomu
the concrete protections of substation will be repaired, maslopriemnoe and oil-sump equipment, buildings and buildings, being on territory of energoob’ekta and other This complex of works will allow considerably to promote reliability of power supply of city
Selfheals.
