A kind of self-extinguishing box-type substation
Technical field
The utility model relates to a kind of box-type substation, specifically a kind ofly can monitor indoor environment temperature automatically, and the unwatched box-type substation of self-extinguishing in time.
Background technology
Along with the fast development of Chinese national economy, the progressively raising of living standards of the people, electric load improves year by year, and the user also has higher requirement to the reliability and the security of power supply.Box-type substation is to integrate high and low pressure switch cubicle and transformer, both can in manufactory, also can assemble the movably preassembled transformer station device of completion at the construction field (site).Box-type substation is operation out of doors generally, is in unattended state, and its surrounding environment is comparatively abominable, because of the operation of variation of temperature and electric power is prone to cause fire.Basically be not equipped with fire fighting device in the present known box-type substation, have only in the box-type substation of only a few to be equipped with some simple manual extinguishing's devices, but do not have automatic fire-extinguishing function.Therefore, cause fire, must carry out the manual extinguishing through the keeper, and when box-type substation is difficult to arrive in the very nick of time the scene apart from the distant keeper of management station, will cause serious electric power accident and economic loss in case box-type substation breaks down.
Summary of the invention
[0003] to above-mentioned defective, the utility model provides a kind of box-type substation with automatic fire-extinguishing function, to strengthen the security of transformer station.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of self-extinguishing box-type substation; Comprise that suspended type ultrafine dry powder constant temperature automatic fire extinguisher (1), box-type substation (2), superconduction start line (8); Wherein suspended type ultrafine dry powder constant temperature automatic fire extinguisher (1) is made up of suspension ring (3), foamite storage tank (4), pressure indicator (5), shower nozzle (6), pressure indicator (5), temperature-sensing element glass marble (7) again; It is characterized by: suspended type ultrafine dry powder constant temperature automatic fire extinguisher (1) suspension is fixed on the top cross beam of box-type substation (2); Its shower nozzle (6) down, the temperature-sensing element glass marble (7) that is equipped with on the shower nozzle (6) all is connected with on each shower nozzle (6) and starts line (8).
The beneficial effect of the utility model is: the safe operation situation that can detect box-type substation automatically; Automatically detect transformer unexpected fire dangerous situation that occurs when operation; Can in time stamp out a fire automatically, strengthen the security performance of box-type substation and can reduce to the economic loss that fire causes minimum.

Marginal data:
Suspended type ultrafine dry powder constant temperature automatic fire extinguisher (1), box-type substation (2), suspension ring (3), foamite storage tank (4), pressure indicator (5), shower nozzle (6), pressure indicator (5), temperature-sensitive glass marble or fusible link (7), superconduction start line (8).
The specific embodiment
Combine accompanying drawing to further specify to this reality is novel at present.
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of unattended self-extinguishing box-type substation of the utility model; It comprises that suspended type ultrafine dry powder constant temperature automatic fire extinguisher (1), box-type substation (2), suspension ring (3), foamite storage tank (4), pressure indicator (5), shower nozzle (6), temperature-sensitive glass marble (7), superconduction start line (8), wherein are equipped with ultra-fine dry powder and driving gas in the foamite storage tank.The mounting disc seat of suspended type ultrafine dry powder constant temperature automatic fire extinguisher is fixed on box-type substation (2) top cross beam, and in the time of fixedly, its shower nozzle (6) should note protecting the temperature-sensing element (7) on the shower nozzle (6) down during installation.When fire took place, when environment temperature surpasses shower nozzle (6) temperature-sensing element, glass marble (7) expanded by heating broke, and jar internal pressure of being pollinated of the pressing plate on the shower nozzle (6) promotes to come off, extinguishing chemical under the driving gas effect fast ejection put out a fire.
The work reason of the utility model is to adopt superconduction to start the fire-fighting principle of line (8): with starting line (8) the startup line (8) on the shower nozzle (6) of each extinguishing device (1) is serially connected during installation; Stranded close and firm is answered in each junction, and bandages with adhesive plaster.Startup line (8) one ends should be fixed on the top, protection zone or be wrapped on the protection thing.When the protection zone breaking out of fire, the superconduction of igniting starts line (8), starts extinguishing device and spurts the extinguishing chemical fire extinguishing automatically.When using superconduction to start line (8) to start, ignite as long as the fire that takes place in the protection zone starts line (8) to superconduction, no matter whether the environment temperature of protection zone reaches the setting value of extinguishing device (1), and extinguishing device (1) all starts automatically puts out a fire; Fire makes the protection zone environment temperature reach extinguishing device (1) setting value, and whether no matter superconduction starts line (8) is ignited, and extinguishing device 1 also all starts fire extinguishing automatically.
