The service of technical diagnostics JOINT STOCK COMPANY of "Mosenergo
- Moscow Regional Administration of Power System Management"
approached the thermal-vision inspection of the thermal networks of
the capital. The application of this method will allow JOINT STOCK COMPANY of
"Mosenergo - Moscow Regional Administration of Power System
Management" to save means for conducting of repair campaign.
Heat viewing is conducted, as a rule, two times per year - by early spring and by late autumn, when it is sufficiently cold and heat conductors work in the heating
regime. At its basis the possibility of obtaining the visible image of objects
with their thermal (infrared) radiation lies. With the aid of the special camera is fixed "anomalous" thermal
field, i.e., the leakage of hot water, not yet appeared on the earth's surface. Inspection is conducted with the aid of the special equipment, which if necessary is established on the helicopter. Into the composition of thermal-vision system also enters personal
computer and software, intended for treating the obtained by camera photographs and
conducting statistics according to the results of inspections. This technology was developed by the specialists GNPP Of
"aerogeofizika". Method gives the possibility to operationally reveal not only
sections, on which already occurred the emergency, but also to determine the places of the disturbance of the
heat-moisture-proof layer of conduit.
The key advantage of thermal-vision inspection consists of that, that in conjunction with the complex of other diagnostic works, it is possible to reveal defects on the underground thermal networks, without producing the dissection of soil. Because of this technology of power engineering they can in proper
time prevent the appearance of interference, ensuring the reliable and uninterrupted heat supply of users in the
winter period. Planning the repair of heat conductors is not less important task of
heat viewing. After comparison with the map of Moscow streets thermal photographs
are transferred to the operational regions of the thermal networks OF
JOINT STOCK COMPANY "Mosenergo - Moscow Regional Administration of
Power System Management". Thus, specialists obtain additional information about the state of
conduits, which is used for determining the necessary volumes of repair work.
At present JOINT STOCK COMPANY of "Mosenergo - Moscow Regional
Administration of Power System Management" attends about 2,5 thousand. km of thermal networks, more than third which already manufactured its period of operation. In 2004 the energy company produced the transfer of more than 85,5 km
of the worn thermal mains. Now the thermal networks OF JOINT STOCK COMPANY "Mosenergo - Moscow
Regional Administration of Power System Management" approached the
creation of special information base, in which will be contained the data about the state of capital
heat-net equipment. Use by complete, the reliable and operationally obtained information with planning of
the repair of heat conductors it will allow approximately to 30% to
increase the effectiveness of expenditures due to the transfer of the
actually being needed the replacement of sections conduits.
