With reference to Fig. 5, data processing module is arranged in a regulator cubicle.Data processing module is used for collecting and process each detector The startup of the signal, the low electric quantity signal of power-supply device and the linkage thereof that gather standby electricity power supply signal, sound and light alarm signal and driving are outstanding Hanging dry powder extinguisher signal.Data processing module has six groups of on-off model to input: 2 smoke detectors 27-1,27-2, and 2 The signal that individual heat detector 21,22, linear infrared beam sensor 28 and low electricity are reported to the police, 2 analog quantity 4-20ma signals are defeated Enter: Temperature Humidity Sensor 20 and the signal of gas detector 24;The output of three groups of switching signals: connect audible-visual annunciator, open standby Electricity power supply and the signal of driving suspension type powder fire extinguisher.
Data processing module 26 is provided with and transmits the RS485 interface of signal and wireless biography to host computer or external fire alarming and control device Defeated device.The RS485 communication interface that data processing module 26 carries is easy to data and is transferred to independent external fire alarming and controlling dress Put.Possess the fire alarming and control device of the functions such as supervision, warning, coordinated signals, for matured product, can be to the report accessed Alert and fire-fighting signal addresses, to determine source and the position of alarm signal.Meet GB4717-2005 " fire alarm control unit ", GB16806-2006 " fire-fighting linkage control system " requirement.
Data processing module 26 carries wireless transmission function, can be by signal by being wirelessly transmitted to independent external host computer.
With reference to Fig. 4, power-supply device includes wind-driven generator, solar panel, accumulator, wind/light complementation controller and AC220V Stand-by power supply.Wind-driven generator and solar panel outdoor open-air are installed, wind/light complementation controller, stand-by power supply, accumulator It is arranged in unified regulator cubicle.Wherein wind-driven generator, solar panel, accumulator respectively with wind/light complementation controller phase Even, wind/light complementation controller and AC220V stand-by power supply provide DC24V power supply for each equipment.
The use of the cable channel cover plate of fire monitoring of the present invention and self-extinguishing is described below.
1 cover plate is arranged
Cable duct is mainly distributed on outdoor, and the cable duct in transformer station is also distributed in 10kV switch gear room, GIS is indoor and indoor Capacitor chamber, arc suppression coil room etc..Its space relative closure but blow-by, belong to unattended region but region is long and narrow.
This cover plate need not lay on cable duct comprehensively, need only be arranged in following location: cable duct corner, cable connector are sentenced And need the position paid close attention to.It is arranged at cable connector, owing to end is typically to make by hand at the scene, by on-the-spot bar Part limits and makes the impact of dispersibility by hand, is the weak link of cable insulation, so strengthening supervision.Cable duct corner Cable is easily pulled when laying, and is easily subject to heating in this place, so strengthening supervision.
It is to be noted that have no occluder between linear infrared beam sensor need to be considered on two cover plates when arranging.
2 monitor in real time
It is arranged on the gas detector on cable channel cover plate body, linear infrared beam sensor, Temperature Humidity Sensor, the spy of sense cigarette Survey the detecting element such as device, the signal detected is delivered to after data processing module 26 collects, can be by signal by being wirelessly transferred To independent external host computer, or it is transferred to independent external fire alarming and control device by RS485 interface, monitors electricity in real time Situation in cable ditch.The data that multiple cable channel cover plates transmit can be addressed by independent external fire alarming and control device.
3 start fire extinguishing
Suspension type powder fire extinguisher, directly can be triggered by fire, or receives startup after electrical control signal.
Nozzle pressing plate is withstood in temperature sensing glass ball upper end, at the nominal operating temperature arranged, i.e. 57 DEG C orange, 68 DEG C of redness, 79 DEG C Expansion explosion when yellow, 93 DEG C or 107 DEG C of greens, 121 DEG C or 141 DEG C are blue, nozzle pressing plate be pollinated pressure inside the tank promote come off and Automatically turning on spray fire extinguishing agent, temperature sensing glass ball meets GB18428-2010 " automatic fire extinguishing system glass bead " requirement.
In the present embodiment, suspension type powder fire extinguisher is provided with electric-controlled type and starts temperature sensing glass ball, and suspension type powder fire extinguisher uses The temperature sensing glass ball of electric-controlled type starts.After fire alarm control system confirms the condition of a fire, send fire extinguishing and instruct to Fire extinguisher, go out Fire controller action connects the electronic starter power supply on extinguishing device, makes glass bead burst, nozzle spray fire extinguishing agent;Or Temperature sensing glass ball, nozzle spray fire extinguishing agent are directly ignited in flame range territory.
If breaking out of fire, Temperature Humidity Sensor, smoke detector, heat detector 21,22, linear infrared beam sensor and The signals such as gas sensor exceed setting threshold values, host computer or fire alarming and control device display alarm information immediately, on-the-spot acousto-optic Reporting to the police and start suspension type powder fire extinguisher: when taking to be transferred to host computer mode, the action of suspension type powder fire extinguisher relies on Its glass bead of naked light explosion in cable duct and start;It is transferred to independent external fire alarm control when being taken through RS485 interface During device mode processed, the action of suspension type powder fire extinguisher relies on its glass bead of naked light explosion in cable duct directly to trigger, or Receive and started by the signal of fire alarming and control device.
For electrically activating during 4 low electricity
If battery goes wrong or the most overcast and rainy calm weather causes accumulator capacity not enough, exceed what wind/light complementation controller set During accumulator capacity, wind/light complementation controller sends electricity low signal and inputs to data processing module 26, and data processing module 26 is defeated Go out control contactor KM2, open backup power supply system and work on.
Embodiment described above is only to be described the preferred embodiment of the present invention, not design and the model to the present invention Enclose and be defined, without departing under design premise of the present invention, the ordinary skill technical staff technology to the present invention in this area Various modification that scheme is made and improvement, all should fall into protection scope of the present invention, the technology contents that the present invention is claimed, Through all recording in detail in the claims.
