The bottle valve of the power source of the existing oil immersed transformer oil discharge and nitrogen charge fire extinguishing device is always under the open state, and the nitrogen charge pipeline (3) is always under the high-pressure state, which can easily cause that the fire extinguishing device is under maloperation and fails to operate. In the utility model, a starting bottle (1) is arranged to be used as drive source for opening a high-pressure nitrogen cylinder (11), a membrane-type bottle valve (4) is arranged on the high-pressure nitrogen cylinder (11), and replaces the common rotary-type bottle valve, an electromagnetic bottle valve (2) on the starting bottle (1) and the membrane-type bottle valve (4) on the high-pressure nitrogen cylinder (11) have two starting-up structures of electrically automatic starting and emergency manual starting, and are respectively provided with a signal output structure, and the function of signal output alarm can be realized when the nitrogen pressure is too low or high.
Description
Technical field
The utility model relates to a kind of extinguishing device, particularly a kind of oil-immersed power transformer oil draining nitrogen filling fire extinguishing device.
Background technology
The bottle valve of the power source nitrogen cylinder of existing oil-immersed power transformer oil draining nitrogen filling fire extinguishing device is in open mode at ordinary times, the nitrogen blanketing valve road is in high pressure conditions for a long time, easily cause and fill the nitrogen flexible pipe, pressure-reducing valve, wearing out of parts such as choke valve, thereby cause the chronic leakage of high pressure nitrogen, when the gas pressure of nitrogen blanketing valve road inner accumulated surpasses oil removal assembly top oil pressure, nitrogen will charge in the transformer body, cause the device maloperation, cause the high-voltage fence security incident, even draw not lifting device maloperation, the pressure of long-time nitrogen cylinder reduces, can cause extinguishing device because of the hypotony tripping, can not be to the transformer action of putting out a fire, thus the safe operation of transformer influenced, cause great power grid accident.
Summary of the invention
The purpose of this utility model is to provide a kind of oil-immersed type transformer oil draining nitrogen filling fire extinguishing device that above-mentioned shortcoming, good airproof performance, use are reliable, can effectively avoid extinguishing device malfunction and tripping that overcomes.
The utility model is achieved in that a kind of oil-immersed type transformer oil draining nitrogen filling fire extinguishing device, comprise FHC, switch board and place oil extraction pipeline in the FHC, the low highly dense valve, oil removal assembly, nitrogen blanketing valve road, draining valve, nitrogen bottle, oil extraction let out to drive valve gear, this nitrogen cylinder bottle valve is the diaphragm type bottle valve, substitute common rotary bottle valve with this valve, be provided with and start bottle as the drive source that starts high-pressure nitrogen bottle, fill nitrogen in the startup bottle, open the bottle valve of high-pressure nitrogen bottle when being used to start extinguishing device.High-pressure nitrogen bottle and the bottle valve that starts bottle respectively are provided with a signal export structure, cross when nitrogen pressure and can realize signal output alarm function when low or too high.
As further improvement of the utility model, this nitrogen cylinder bottle valve and start on the bottle bottle valve this releasing pressure automatically hole respectively is set, and have charged automatic startup and emergently manually boot two kinds and start structures.
Operation principle of the present utility model is: after device receives fire signal, DC current (DC24V, 1.5A) by fire alarm control unit output starts electromagnet, electromagnet starts the diaphragm of releasing that release punctures the broken electromagnetism bottle valve of acupuncture, discharge driving gas, driving gas is opened the bottle valve of high-pressure nitrogen bottle through the primer liner copper pipe, thereby finishes the startup of system.Just in case when the power failure emergency occurring, available finger is held and is started bottle safety fastener handle, and safety fastener is pulled out, bounce hand push button, make the diaphragm of releasing that punctures the broken container value of acupuncture, discharge driving gas, use the same method the bottle valve of manual unlocking high-pressure nitrogen bottle.
Compared to existing technology, this device solves nitrogen blanketing valve road sealing and reliable in action problem, prevented the leakage of nitrogen, improved the reliability of extinguishing device action.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1. start bottle, 2. electromagnetism bottle valve, 3. nitrogen blanketing valve road, 4. diaphragm bottle valve, 5. choke valve, 6. oil removal assembly, 7. draining valve, 8. switch board, 9. valve gear is driven in oil extraction, 10. FHC, 11. high-pressure nitrogen bottles.
The specific embodiment
As shown in the figure, the utility model comprises FHC (10), switch board (8) and places high-pressure nitrogen bottle (11), startup bottle (1), nitrogen blanketing valve road (3), choke valve (5), oil removal assembly (6), draining valve (7), oil extraction in the FHC (10) to drive valve gear (9).Electromagnetism bottle valve (2) on the startup bottle (1) links to each other by nitrogen blanketing valve road (3) with the diaphragm bottle valve (4) on the high-pressure nitrogen bottle (11), after device receives fire signal, by the electromagnet on DC current (DC24V, 1.5A) the startup electromagnetism bottle valve (2) of fire alarm control unit output, electromagnet starts the diaphragm of releasing that release punctures the broken electromagnetism bottle valve (2) of acupuncture, discharge driving gas, driving gas is opened the diaphragm bottle valve (4) of high-pressure nitrogen bottle through primer liner nitrogen blanketing valve road (3), thereby finishes the startup of system.Diaphragm bottle valve (4) on the high-pressure nitrogen bottle (11) and the electromagnetism bottle valve (2) that starts on the bottle (1) respectively are provided with a releasing pressure automatically hole, can prevent that the chronic leakage of gases at high pressure from causing the valve body error starting, diaphragm bottle valve (4) and electromagnetism bottle valve (2) are when normally starting, the releasing pressure automatically bore closure, the storage of higher pressures gas that prevents normal release is let out the hole discharge from this, thereby finishes the normal release of gas.Diaphragm bottle valve (4) and electromagnetism bottle valve (2) have charged automatic startup and emergent manually boot two kinds and start structures, just in case when the power failure emergency occurring, available finger is held and is started bottle safety fastener handle, safety fastener is pulled out, bounce hand push button, make the diaphragm of releasing that punctures the broken container value of acupuncture, discharge driving gas, same method, the bottle valve (4) of manual unlocking high-pressure nitrogen bottle (11) diaphragm.This scheme has solved the sealing and the reliable in action problem on existing oil draining nitrogen filling fire extinguishing device nitrogen blanketing valve road; prevented the chronic leakage of nitrogen; improved the reliability of extinguishing device action; effectively avoided by the Accident of Transformer that error action of device is done and the tripping work causes, thereby protected the safe operation of high-voltage fence.
Electromagnetism bottle valve (2) band signal export structure on diaphragm bottle valve (4) on the high-pressure nitrogen bottle (11) and the startup bottle (1), cross when nitrogen pressure and can realize signal output alarm function when low or too high, alarm signal is transferred to control system in the switch board (8) in the master-control room, and with sound and light alarm.
