Abstract
The utility model provides an electrical cabinet with a fire hazard alarm system. A Plurality of electrical devices, an air sampling pipe network for carrying out air exhaust sampling for the electrical devices, a smog detector for detecting gas outputted by the air sampling pipe network, and a display control unit for receiving an output signal of the smog detector and uploading the output signal are mounted in the cabinet body. With the electrical cabinet, fire hazard, even smoldering fire can be detected at a very early stage of a fire hazard, through collecting air samples around the electrical devices and sending the samples in a centralized manner to the smog detector to carry out detection; and fired hazard situation is detected in real time when fire hazard occurs, so as to facilitate timely and right judgments of monitoring personnel and remote operation personnel, and further to reduce damages of an accident.
Description
Technical field
The utility model relates to a kind of electrical box, relates in particular to a kind of electrical box that possesses utmost point incipient fire warning system.
Background technology
Adopting unattended remote automatic monitoring system is the development trend of change, power distribution station, but the defect of remote monitoring maximum is that fire is not had to the way of effectively processing, once electric equipment breaking out of fire, just may expand rapidly burning apparatus and even spread to Other related equipment, cause large-scale destruction and economic loss.And the warning of former seconds and the expansion information of fire condition are afterwards occurring fire, the monitor staff's of Dui Yu transformer station analysis field condition is extremely important.
Conventional scheme is at the corridor of electrical box spatial placement smoke detector now, just at smoke detector, finds after smog, starts to report to the police frequently.Like this following problem that exists is set: 1, smoke detector only gathers after certain degree at smog, just can sense the generation of fire, and this static detection method is subject to spacial influence larger, the position that the installation position of smoke detector and fire occur conventionally can not be just at the three unities, thereby can not find fast fire dangerous situation; 2, the signal that smoke detector sends is interrupted in originally, only at flue gas, gather certain degree and just can stablize, will cause like this monitor staff's paralysis, inadequate to alarm signal attention degree originally, think it is wrong report by mistake, delayed best processing opportunity; 3, for the early alert of trying one's best, multiple sense cigarette and temperature detector are set conventionally, so just need to configure a large amount of detection probe, cause the huge of fire detection system, brought higher failure rate, reduced equipment dependability.
Electric equipment needs the meaning of utmost point early alert to be: 1, the integrated degree of electric equipment is more and more higher, and function is more complete, and volume is less, and cost is more expensive, more needs protection.2, the employing of ventilation and air-conditioning equipment, the temperature that fire is produced plays cooling effect, and smog has been played to diluting effect, needs high sensitivity.3, the plastic insulating layer of electric wire, cable, for increasing anti-flammability, has all added the additive of halide and phosphate and so on.During burning, can discharge toxic gas and corrosive gas, therefore will avoid forming dense smoke.4, electric equipment can not be shut down or break in service, needs early alert.
Based on above-mentioned, proposing a kind of electrical box that possesses utmost point incipient fire warning system becomes the problem that the utility model faces.
Utility model content
Technique effect of the present utility model can overcome above-mentioned defect, and a kind of electrical box that possesses utmost point incipient fire warning system is provided, and early warning continuity is strong opportunity for its warning, simple in structure, safeguard less, can meet the requirement of power station being carried out to fire alarm.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electrical box that possesses fire alarm system, some electric equipments, the air sampling pipe network in order to each electric equipment is bled and sample are installed in this casing, in order to detect the smoke detector of air sampling pipe network output gas, and the indicative control unit in order to receive smoke detector output signal and to be uploaded.
Further, described air sampling pipe network comprises air pump, trunk pipeline and each branch road tubule being connected with trunk pipeline, and described trunk pipeline connects described smoke detector.
Further, between described trunk pipeline and described smoke detector, filter is installed.
Further, described each electric equipment is all arranged in a closed cabinet body separately, and this cabinet top connects branch road tubule, and below has air-vent.
Further, described smoke detector and indicative control unit are installed on described box inside wall.
Further, described trunk pipeline is fixed on top in casing.
Compared with prior art, advantage of the present utility model and good effect are as follows:
The utility model is by gathering electric equipment surrounding air sample, and concentrate and be sent to smoke detector detection, can go out fire dangerous situation in the utmost point earlier detection of electrical fire, or even smoldering fire, detection of fires situation in real time after there is the condition of a fire, be convenient to monitor staff and remote operation personnel make correct judgement in time, and then the infringement of minimizing accident.
The utility model is reported to the police opportunity early, and simple in structure, maintenance is lacked, and can meet the requirement of power station being carried out to fire alarm.
Read by reference to the accompanying drawings after embodiment of the present utility model, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment electrical principle block diagram;
Fig. 2 is the utility model example structure schematic diagram;
In each figure: 1, casing; 2, electric equipment; 3, cabinet; 4, trunk pipeline; 5, branch road tubule; 6, smoke detector and indicative control unit.
Embodiment
With reference to figure 1 and Fig. 2, the present embodiment proposes a kind of electrical box that possesses fire alarm system, and electric equipment 2, air sampling pipe network, smoke detector and indicative control unit 6 are installed in this casing 1.
Totally 8 groups of the present embodiment electric equipments, certainly, also can specifically arrange group number as required.
Described air sampling pipe network, can be the set of multichannel pipeline, for simplicity, comprise air pump, trunk pipeline 4 and each branch road tubule 5 being connected with trunk pipeline 4, described trunk pipeline 4 connects described smoke detector, and each branch road tubule lays respectively at respectively to be organized near electric equipment.Under the effect of air pump, by each branch road tubule 5, extract electric equipment gas around, and output in smoke detector by trunk pipeline 4.Smoke detector is analyzed above-mentioned gas, and detection signal is exported to indicative control unit as the concentration of smog, and described indicative control unit is uploaded to higher level's scheduling and operator on duty by above-mentioned signal, thereby can more early find and avoid fire.
Thereby in order to exist impurity to affect the detection of smoke detector in the air that prevents from sucking, the present embodiment is provided with filter at trunk pipeline and described smoke detector junction.
