Description
Technical field
The utility model relates to a kind of extinguishing device, and particularly a kind of oil-immersed power transformer fills the nitrogen extinguishing device, is applicable to the quick extinguishing of oil-immersed power transformer and similar oil-filled power equipment.
Background technology
The nitrogen release that existing transformer fills the nitrogen extinguishing device is to finish by the unlatching of nitrogen relief valve, each connecting portion of its valve inner mainly seals by elastic rubber gasket and sealant, valve body relies on mechanical actuation device to open, after receiving actuating signal, fill the action of nitrogen electromagnet specifically, its draw bar is drawn back, weight loses to support and falls, pound down the valve rod that fills the nitrogen relief valve, valve body is opened, and discharges nitrogen.Rubber gasket wears out easily, weares and teares and distortion in long-time, thereby causes the chronic leakage of nitrogen; After the action of nitrogen relief valve, nitrogen also may be revealed from valve seal, causes the gas shunting, thereby has influence on the release time of nitrogen.Can not guarantee after weight falls that valve body can open fully, whether can discharge smoothly thereby have influence on nitrogen.Filling the nitrogen relief valve relies on travel switch to accept actuating signal, whether travel switch, the action of filling nitrogen electromagnet and valve body directly have influence on the nitrogen relief valve and can normally open, and when producing, need constantly to adjust travel switch, fill position component such as nitrogen electromagnet, weight, valve body, be difficult for installing, debugging, waste time and energy.The actuating signal of tradition extinguishing device is by a plurality of contact relays, time relay control, and the contact is many, can produce mechanical wear and electric arc burn, and easily loose contact causes signal correctly not send; And wiring is many, reliability, maintainable poor; Be not easy to realize decentralised control, centralized management, real-time data acquisition, Long-distance Control and browse.
Summary of the invention
The purpose of this utility model be to provide a kind of overcome above-mentioned shortcoming, good airproof performance, use reliable, can realize that the oil-immersed power transformer of on-line monitoring, Long-distance Control fills the nitrogen extinguishing device.
The utility model is achieved in that a kind of oil-immersed power transformer fills the nitrogen extinguishing device, comprise FHC, switch board and place nitrogen bottle in the FHC, the low safety valve, oil removal assembly, nitrogen blanketing valve road, oil extraction safety valve, draining valve, oil extraction let out to drive valve gear, be provided with on this nitrogen blanketing valve road and fill the nitrogen magnetic valve, the PLC controller is set in this switch board, fills nitrogen extinguishing device, fault alarm and the signal is far passed by PLC controller opens or control.
As further improvement of the utility model, this fills the nitrogen magnetic valve has charged automatic startup and emergent manually boot two kinds and start structures.
Operation principle of the present utility model is: when filling the nitrogen extinguishing device and not moving, it is normally closed to fill the nitrogen magnetic valve, and nitrogen is charged in the pipeline of magnetic valve upstream, and after receiving actuating signal, magnetic valve is opened fast, discharges nitrogen.If magnetic valve do not switch on, can open manually, guaranteed under the no power situation normally the opening of magnetic valve like this.In switch board, send the control signal of extinguishing device, realize fault alarm and the signal is far passed by the PLC controller.
Compared to existing technology, this device solves fill nitrogen relief valve sealing and reliable in action problem, prevented the leakage of nitrogen, improved the reliability of extinguishing device action; Adopt the PLC controller to make that the device wiring is simple, extensibility, maintainable good; Can carry out Automatic Control and telecommunication network control to device, each key component duty of extinguishing device and transformer correlation behavior are carried out real time on-line monitoring.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, FHC, 2, the nitrogen bottle, 3, fill the low safety valve of letting out of nitrogen magnetic valve, 4, the low safety valve of letting out, 5, the oil removal assembly, 6, the nitrogen blanketing valve road, 7, the oil extraction safety valve, 8, draining valve, 9, switch board, 10, the PLC controller, 11, oil extraction drives valve gear.
The specific embodiment
As shown in the figure, the utility model comprise FHC 1, switch board 9 and place nitrogen bottle 2 in the FHC 1, fill nitrogen magnetic valve 3, the low safety valve 4, oil removal assembly 5, nitrogen blanketing valve road 6, oil extraction safety valve 7, draining valve 8, oil extraction let out drive valve gear 11.Fill nitrogen magnetic valve 3 and be installed on the nitrogen blanketing valve road 6 nitrogen bottle 2 and low letting out between the safety valve 4, have charged automatic startup and emergently manually boot two kinds and start structures.When extinguishing device did not move, it was normally closed to fill nitrogen magnetic valve 3, and nitrogen is charged in the pipeline of nitrogen magnetic valve 3 upstreams, after receiving actuating signal, filled nitrogen magnetic valve 3 and opened fast, discharged nitrogen.If filling nitrogen magnetic valve 3 does not switch on, can open manually, guaranteed like this to fill normally opening of nitrogen magnetic valve 3 under the no power situation.This scheme has solved prior art and has filled nitrogen relief valve sealing and reliable in action problem, has prevented the leakage of nitrogen, has improved the reliability of extinguishing device action.
PLC controller 10 is installed in switch board 9, open or control by PLC controller 10 and fill the nitrogen extinguishing device, realize fault alarm and the signal is far passed, this extinguishing device can design special real-time monitoring system software in order to accepting analytic signal, realizes whole extinguishing device duty real time on-line monitoring, Long-distance Control and data remote and the function browsed.Extinguishing device judges whether to need to start the fire extinguishing program according to data on the main control system and alarm; Also the data and the alarming value that can set in advance according to the user judges whether to surpass predetermined value by main control system, then starts the fire extinguishing program automatically if surpass this numerical value.But control the recovery of opening, stopping of fire extinguishing action and various states by the network remote live.This device has functions such as detection, warning, fire extinguishing, real time on-line monitoring, Long-distance Control and browsing data, has realized the automation control of overall process, safety, reliable.
