OAO «Generating company» (republic of Tatarstan) continues realization of the program of technical rearmament and reconstruction of the opened distributive devices (I YELL) of teploelektrostanciy of republic. The question is not only about replacement «old» on the same «new». It «new» differs from «old» on principle, as supposes the increase of economy and reliability of the station. In same queue, it positively tells and in-process at the wholesale market electric power
and powers, and also on the financial results of generating company. So, systematic replacement is produced morally and physically out-of-date switches 110-500 kv and transformers of current and tension 110-220 kv on elegazovye, switches 6-10 kv on vacuum with simultaneous
substituting of zaschit by a microprocessor, disconnectors – on modern, inputs of oily switches and transformers – on impermeable. In 2008 replacement of air switches is completed 110 kv in the closed distributive device (ZRU) of Kazanskoy Tec-1 and air
switches 500 kv on elegazovye on Nizhnekamskoy hydroelectric power PLANT. It allowed considerably to increase reliability of these stations. Through them delivery to power is carried out in the grid of republic and single grid of Russia. Replacement of switches will be completed in a current year
500 kv on Zainskoy GRES. Replacement of switches proceeds 110 kv in YELL -110 kv Kazanskoy Tec-2, Kazanskoy Tec-3 and in ZRU of Nizhnekamskoy TEC. Due to these measures reliability of energy supply of enterprises of petrochemical industry of Republic increases substantially,
in particular OAO «Kazan’orgsintez», OAO «Nizhnekamskneftekhim», OAO «Nizhnekamskshina», OAO «TAIF-NK». There is a stake of elegazovykh switches on January, 1, 2009 110-500 kv from the general amount of OAO set on the stations «Generating company» made more 50%. In a flow
25 years major repairs for them practically are not required. It means that annually «Generating company» will save a more than 25 million rub on these switches
