Abstract
The invention discloses a fire preventing and controlling method for an underground transformer substation. The method comprises the following steps: 1) dividing fire-preventing zones in the underground transformer substation according to a process system; 2) fully safeguarding the underground transformer substation by a full-automatic fire-preventing system; 3) arranging a fire detecting warning control system in the underground transformer substation; and 4) arranging an smoke discharge preventing system in a public zone and a technology device room. Compared with the prior art, the fire preventing and controlling method disclosed by the invention gives a full consideration of the features of deep underground depth, difficult fire extinguishment and smoke discharge and the like and is capable of guaranteeing production and safety and controlling fire immediately in case of finding hidden danger of fire so as to reduce loss caused by fire based on a principle of self-prevention and self-rescue.
Description
Technical field
The present invention relates to a kind of fire prevention and control method, especially relate to a kind of underground and become station fire prevention and control method.
Background technology
Underground substation is one of of paramount importance functional area in building, because equipment is numerous, also fire possibility occurrence is become larger, this just makes, and how fire preventing controls the very important of the degree change of fire with effective, for layout and the fire fighting mode of large-scale substation, not yet there is ripe referential standard at present, the construction of transformer station is beyond the scale standard of existing design fire safety rules and code, therefore adopt rational Design Scheme of Fire-Control to the fire safety ensureing transformer station, avoid or reduce fire occurring, the project construction of substation project and long-term safety are run and has great significance.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of underground substation fire prevention and control method are provided.
Object of the present invention can be achieved through the following technical solutions:
Underground substation fire prevention and control method, is characterized in that, comprises the following steps:
1) underground substation is pressed process system and divide fire district, each fire compartment has an emergency staircase to lead directly to ground, and be provided with all the people present's Fire lift, each fire compartment has the second emergency exit to be connected with adjacent fire compartment, have belt fire-fighting between each fire compartment, evacuate main channel and be connected with emergency staircase and Fire lift, each use is partly connected with main channel by aisle; 2) automatic fire extinguishing system full guard is taked in this underground substation, corresponding fire suppression measures is taked according to different object of protections, by the classification of fire hazards in each room, the room of the Class Cs such as oil-containing electrical equipment is adopted to the fire suppression measures of thin water spray extinguishing, less and the class D of automatic water jetting fire-fighting or penta class electric room should not be adopted to adopt extinction using gas to add automatic water jetting fire-fighting for combustible, cable interlayer, passage and all penta class rooms that can fire-fight by water and passage adopt automatic sprinkling fire-extinguishing; 3) fire detecting and alarm control system is set; 4) in public domain, smoke control system is set with process equipment room.
Compared with prior art, the present invention takes into full account that the subterranean depth of underground substation is dark, fire attack and the feature such as fume emission is difficult, based on from anti-principle of saving oneself, ensure that production and safety, and when there is disaster hidden-trouble the very first time control the intensity of a fire thus reduce the loss.
Detailed description of the invention
1) by process system transformer station subregion, four independently fire compartments are divided into.Each fire compartment has an emergency staircase to lead directly to ground, and is provided with all the people present's Fire lift.Each fire compartment has the second emergency exit to be connected with adjacent fire compartment.Have belt fire-fighting between each fire compartment, evacuate main channel and be connected with emergency staircase and Fire lift, each use is partly connected with main channel by aisle.
2) take automatic fire extinguishing system full guard, take corresponding fire suppression measures according to different object of protections.By the classification of fire hazards in each room, the room of the Class Cs such as oil-containing electrical equipment is adopted to the fire suppression measures of thin water spray extinguishing; Less and the class D of automatic water jetting fire-fighting or penta class electric room should not be adopted to adopt extinction using gas+automatic water jetting fire-fighting (as subsequent use) for combustible.Cable interlayer, passage and all penta class rooms that can fire-fight by water and passage adopt automatic sprinkling fire-extinguishing.
3) arrange fire detecting and alarm control system, unmanned place needs device height reliable, and not by electromagnetic interference influence, without wrong report.Aspirating smoke detector is adopted to electrical equipment room.The general detectivity adjustable range 0.005% ~ 20% of this detector, compared with smoke point detector sensitivity 3% ~ 5%, aspirating smoke detector has high sensitivity, can carry out detecting at Initial Stage of Fire and report to the police, generate initial stage elimination disaster hidden-trouble at fire, the loss of fire is dropped to minimum.
4) in public domain and process equipment room arranges smoke control system, and transformer station's smoke controlling arranges scope and mainly contains: the smoke controlling of smoke bay and the smoke controlling in process equipment room in public domain.The former is mainly for evacuating personnel during fire, and this is similar to the smoke evacuation in civil buildings; The latter is then mainly for safe operation and the production restoration of equipment.
