Cable ditch is that cable concentration lays most places, is widely used in transformer station and a large amount of civilian installation, and its fire risk is the biggest:
Cable in ditch is the cable of band outer insulation jacket, outer insulation jacket be mainly composed of high polymer such as plastics, rubber and rubber,
The cable of some specific use also has many additives；Cable typically uses built on stilts cluster laying, and residing environment is the most poor,
Operation maintenance difficulty；Surveillance and control measure plus cable running safety is more single, it is impossible to day and night monitor in the range of all fronts, therefore
To accident or the hidden dangers in its running such as cable breaking out of fires, it is impossible to control timely and effectively, breaking out of fire
Probability the highest；Meanwhile, cable duct is the most local narrow and small, and cable detonation once occurs in cable duct, even if power-off, the intensity of a fire is also
Being difficult to control, the intensity of a fire can quickly be prolonged combustion along Cable Group and be expanded, and existing extinguisher is often difficult to fully put into so that the intensity of a fire
Can not be checked in little scope and be put out in short-term.
Transformer station is the assembly place of transmission and disttrbution in power system, plays voltage of transformation, accepts and distribute electric energy, control electric power
Flow to and adjust the effect of voltage.The transformer station that significance level is the highest, is all provided with within its cable floor, control room, cable shaft etc.
Put fire automatic detection warning, and automatic fire-extingishing fire device is set according to fire-fighting relevant code.But substantial amounts of cable duct in standing,
And transmission line of electricity also has substantial amounts of cable duct, all do not have effective fire fighting monitoring and fire extinguishing to arrange.It addition, domestic 10kV
PVC plastic cable below electric pressure is widely used, and its defect is the most aging, easy firing.Particularly common plastics cable
The most easily catching fire, and the HCl gas produced passes through gap, hole can permeate, and electric device is indoor, wet gas forms dilute salt
Acid is attached on each devices such as electrical equipment, power plate, control and sealer, and forms one layer of conducting film, seriously reduces equipment
With the insulating properties of connection circuit, after fire is extinguished, still affect safe operation.Even if using insulation cleaning agent cleaning performance the most not
Good, form secondary harm.High temperature before combustion can make insulating barrier, rubber sheath produce a large amount of CO because of pyrolysis, if electric
Cable ditch is disposed in the interior, then can damage personnel.

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.
