Abstract
The utility model discloses a detecting device of a foam spray fire extinguishing system, which is composed of a line type temperature sensing cable, a converter, a human-computer interface, a PLC and a temperature module. The human-computer interface, the PLC and the temperature module are mounted in a fire control cabinet, a beginning end of the line type temperature sensing cable is uniformly wound surrounding a main transformer and on an oil conservator in sine wave shape, and after being wound, a finishing end and the beginning end are in parallel connection on an input terminal of the converter. The utility model is high in detecting precision, and can digitally display temperature of the surface of the main transformer to bring convenience for observation. The detecting device of a foam spray fire extinguishing system is simple in structure, high in reliability and convenient in use and maintenance, and provides reliable protection measures for operation of the transformer.
Description
Technical field
The utility model relates to a kind of fire-fighting fire extinguishing sniffer, refers in particular to the special-purpose foam spray fire extinguishing system sniffer into fire-fighting fire extinguishings such as oil immersed power transformer, Oil-burning Boiler Room, fuel electric generator room, small-sized oil storage tank, kart storehouse, small-sized freight car temporary repairing shed, small-sized oil depots.
Background technology
At present, the fixed extinguishing system of domestic transformer adopting mainly is a water spray fire extinguish system, and this is to be applied to outdoor large transformer fire-fighting a kind of fixed extinguishing system the earliest.This system is by underground conservation pool, intake pipe, fire pump, descend fire chief net, water spray by-pass valve control, transformer water atomizing standpipe, horizontal branch pipe, atomizer, starting mode of pump control and protective device etc. to form annularly.In the winter of cold, the water capacity in the water tower is easily frozen and the bursting by freezing pipeline, because variable frequency pump is in the speed governing operating condition all the time, because of impurity in the water weares and teares very big to pump, compare with the variable frequency pump in the running water system, supporting fire supply system such as water pump, pipe network takes up an area of greatly, cost is high, and the regular maintenance management also bothers.What at present general control mode adopted is that temperature sensing cable is wrapped on the transformer body, temperature feedback signal by temperature sensing cable is given fire alarm control unit, the shortcoming of this kind mode is because the maintainer steps on temperature sensing cable when overhauling main transformer disconnected easily, as fail in time to find, can the safety of main transformer be constituted a threat to.Research and develop a kind of simple in structurely, it is necessary that the user can come the different novel fire-fighting system of flexible combination with protection domain according to the fire type of protected body.
The utility model content
The technical problems to be solved in the utility model provides a kind of foam spray fire extinguishing system sniffer, this foam spray fire extinguishing system sniffer is simple in structure, make up flexible and changeable, wide, the anti-adverse environment, convenient for installation and maintenance of its temperature detection device monitoring range.
The utility model will be separated fast technical problem and be realized by following scheme: foam spray fire extinguishing system sniffer.Be installed in the Fire Control Cabinet etc. by linear temperature sensitive cable, converter, (man-machine interface, PLC, thermal module) and form.
Employing with linear temperature sensitive cable be wrapped in uniformly main transformer around and on the conservator of transformer, can reflect accurately around the main transformer everywhere temperature and the temperature of conservator, when the main transformer temperature exceeds 105 ℃ of design temperatures, promptly give main transformer Fire Control Cabinet feedback signal, send warning.
The utility model also comprises following scheme: linear temperature sensitive cable is by the flexible cable of two temperature and resistance leads after the crust shielding processing.It reaches on the conservator around main transformer uniformly with the shape of sine wave, the temperature of main transformer is carried out 24 hours continuous monitorings, when finding position, main transformer somewhere sudden temperature rise, when temperature exceeds 105 ℃, linear temperature sensitive cable is sent to the temperature and resistance signal in the converter, resistance signal is become the signal of telecommunication of 4～20AM through converter, feed back to the thermal module among the PLC in the Fire Control Cabinet, in thermal module is sent to man-machine interface in the fire-fighting control after relatively, Fire Control Cabinet is promptly sent sound and light alarm, Deng the main transformer high-pressure side, medium voltage side, after the low-pressure side outage, can start froth fire extinguishing system main transformer is carried out quick extinguishing.
The utility model has the advantages that: foam spray fire extinguishing system sniffer, simple in structure, reliability is high, working service is convenient, for the transformer operation provides reliable protective measure.
Because the linear temperature sensitive cable in the foam spray fire extinguishing system sniffer is uniformly around main transformer and on the conservator of transformer, its heat detection certainty of measurement height, linear temperature sensing cable can show the main transformer surface temperature with digital form, be convenient to observe.Anti-adverse environment, convenient for installation and maintenance.
Description of drawings
Below in conjunction with accompanying drawing for an embodiment:
Fig. 1 is the three-dimensional view of main transformer
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is a converter case front view
The specific embodiment
As Fig. 1, Fig. 2, foam spray fire extinguishing system sniffer.Be installed in the Fire Control Cabinet etc. by linear temperature sensitive cable, converter, (man-machine interface, PLC, thermal module) and form.Its feature: be to adopt shape uniform winding reaching around the main transformer on the conservator, twine back clearing end and starting end parallel way and be connected on the converter input terminal with linear temperature sensitive cable starting end sine wave.Can reflect accurately around the main transformer everywhere temperature and the temperature of conservator, when the main transformer temperature exceeds 105 ℃ of design temperatures, promptly give main transformer fire-fighting control flow feedback signal, send warning.A main transformer needs about 200 meters linear temperature sensitive cable.
Converter case in converter case, the foam spray fire extinguishing system sniffer as shown in Figure 3 is fixed on the side of main transformer with the Luo bolt.The input of converter opens top with temperature sensing cable and clearing end is in parallel in succession, and the thermal module in output and the main transformer switch board among the PLC is connected.
Claims (2)
1, foam spray fire extinguishing system sniffer is by linear temperature sensitive cable, converter, and man-machine interface, PLC, thermal module are formed; Described man-machine interface, PLC, thermal module are installed in the Fire Control Cabinet, its feature: be to adopt shape uniform winding reaching around the main transformer on the conservator with linear temperature sensitive cable starting end sine wave, twining back clearing end and starting end parallel way is connected on the converter input terminal, can reflect accurately around the main transformer everywhere temperature and the temperature of conservator, when the main transformer temperature exceeds 105 ℃ of design temperatures, promptly give main transformer fire-fighting control flow feedback signal, send warning.
2, a kind of foam spray fire extinguishing system sniffer according to claim 1 is characterized in that, a described main transformer needs about 200 meters linear temperature sensitive cable.
