EXAMPLES OF PROTECTION OF ENERGY OBJECTS

LIST OF BUILDINGS, PREMISES AND CONSTRUCTIONS OF RAO UES OF RUSSIA ENTERPRISES, TO BE EQUIPPED BY AUTOMATIC FIRE EXTINGUISHING DEVICES

1. ENERGY ENTERPRISES

1.1.Transformers and reactors with a voltage of 500 kV and higher irrespective of capacity, as well as transformers with a voltage of 220-330 kV with an output of 200 MBA or more.

1.2. Transformers with a capacity of 63 MBA and more with a voltage of 110 kV and above, installed in the chambers of closed substations of deep entry and in closed distribution plants of power stations and substations.

1.3. Transformers with a voltage of 110 kV and higher with a unit capacity of 63 MBA or more installed near the building of a hydroelectric power station.

1.4. Cable facilities (cable tunnels, closed galleries, floors, passage cable shafts) of thermal power plants irrespective of capacity, hydroelectric power stations with a capacity of 100 MW and above, substations with a voltage of 500 kV and above, as well as closed substations of 110 kV deep input with 63 MVA transformers and higher .

1.5. Cable facilities (cable tunnels, closed galleries, floors, passage cable shafts) of power stations and substations with oil-filled cables, with the exception of cable structures, in which oil-filled cables are laid in metal pipelines.

1.6. Underground spaces of rooms for computers, systems for centralized control and management of the technological process of thermal and hydraulic power stations, as well as substations with a voltage of 500 kV and above.

1.7. Closed warehouses flammable liquids, as well as rooms with installations for the regeneration of oils with an area of ​​500 m2 and more.

Notes:

  1. This list applies to the projected and reconstructed buildings, premises and facilities of enterprises.
  2. The choice of fire-fighting equipment (water, foam, gas or powder) is determined by technological requirements and feasibility study.

The above objects are proposed to be protected using powder fire extinguishing systems based on powder fire extinguishing module «Buran» and fire extinguishing aerosol generators «TOR».

According to paragraph 9.1.6 of SP 5.13130.2009 «Fire alarm and fire extinguishing systems are automatic. Norms and design rules «-» Fire-extinguishing powders must comply with the requirements of GOST R 53280.4. In this case, the breakdown voltage parameter is not taken into account for the pulsed powder fire extinguishing modules. »

Since the modules «Buran» for their design and tactical and technical indicators are related to the impulse action modules, i.e. The time of submission of the extinguishing agent in them does not exceed 1 sec, they fall within the scope of this paragraph.

Thus, fire extinguishing systems based on powder extinguishing modules «Buran» and self-extinguishing fire extinguishers produced by the Group of Companies «EPOTOS» can protect energy facilities regardless of the voltage on the contacts of electrical equipment:

  • Lead-in cells of transformers;
  • Oil circuit breakers (even in the open air);
  • Shields КРУН, КРУ, relay boards, etc .;
  • Transformer chambers, transformer points;
  • Cable ducts, tunnels, ducts, etc .;
  • Main shields, control rooms, computer centers;
  • Warehouse, technological and household premises of any area, including explosive rooms.

 

Modules «Buran-8W», installed as part of an independent fire extinguishing system.

To protect the conditionally sealed energy facilities, the association «EPOTOS» offers the use of generators of the fire-extinguishing aerosol «ТОР-1500», «ТОР-3000».

The fire extinguishing aerosol generators «ТОР-1500», «ТОР-3000» are successfully used as part of ship systems of aerosol bulk fire extinguishing, in container diesel generator sets, in the premises of transformer substations, cable channels, cable cellars, etc.
