Description
Technical field
The present invention relates to technical field of wind power generation, particularly relate to a kind of gas fire-fighting controller.
Background technology
The disaster hidden-trouble of blower interior is many.At present, wind energy turbine set does not have or seldom installs intelligent fire equipment, is only put two tool dry powder extinguishers in fan engine room mostly.Blower fan unmanned, can not the early detection condition of a fire, if breaking out of fire, easily brings about great losses.Automatic fire protection system monitors the condition of a fire hidden danger that blower interior may exist in real time, and notifies gas fire-fighting controller, controls gas fire-extinguishing medium and puts out the condition of a fire occurred.
Blower interior electromagnetic environment is more harsh, due to the existence of high-frequency apparatus and powerful device, causes comprising conduction interference between spacing electromagnetic radiation and cable and is all difficult to avoid.Between gas fire-fighting controller and gas fire-extinguishing medium, control line wiring is coupled to interfering signal unavoidably, in order to avoid the property loss that gas fire-extinguishing medium causes due to interfering signal false triggering, even personnel suffocate, very high to the reliability requirement of gas fire-fighting controller.
Blower interior need be divided into multiple not overlapping area of fire protection mutually, comprise at the bottom of wheel hub district, cabin district, tower and bear one deck etc. at the bottom of one deck, tower, multiple cabinet needing monitoring is there is again in each fire district, the grouping of gas fire-extinguishing medium, distribution, triggering are relatively complicated, require relatively high to the circuit volume of gas fire-fighting controller.
Existing traditional gas Fire extinguisher is difficult to all meet the requirement of Wind turbines internal operation on circuit volume He in EMC Design two.
Multiloop function due to gas fire-fighting controller inside is realized by the circuit units of multiple homogeneity; this circuit units is responsible for receiving, process information and send instruction, and the part of interface wherein receiving information and the interface sending instruction all need to adequately protect.
Feedback information input exports with instruction and is all connected gas fire-extinguishing medium, and this part function needs outside wiring to realize, so need to protect it.Panel command reception is carried out for button, and this part port protection needs to consider static discharge, comprises the protection of contact discharge and atmospherical discharges two kinds of patterns.Communication needs wiring to realize equally, must protect port.
The design capacity of gas fire-fighting controller is exactly controllable loop sum.The feeder number of gas fire extinguisher can increase according to design or minimizing circuit units realizes.Consider the electromagnetic environment that blower interior is relatively harsh, it is more complete that port-guard part needs do, and inevitably increases the area of circuit units circuit board.Because blower interior area of fire protection divides relatively complicated, need the area of fire protection of multiple independent control, therefore need multiple circuit units.Blower interior space is compact, also has a definite limitation to the volume of gas fire-fighting controller, can not stop escape way when one deck is installed at the bottom of tower.If gas fire-fighting controller volume is excessive simultaneously, requires also can rise to the material of rack, cause holistic cost significantly to rise.
Therefore, there is following shortcoming in current gas fire-fighting controller:
1, the feeder number of gas fire-fighting controller can not meet blower fan area of fire protection division requirement;
2, Electro Magnetic Compatibility does not meet the demands;
3, because extinction using gas cellar area is comparatively large, cause gas fire-fighting controller volume too large, cost increases, and installs difficulty.
Summary of the invention
Loop sum, interactional technical problem between Electro Magnetic Compatibility and controller volume three in the design of Wind turbines gas fire-fighting controller is applicable to for solving, the present invention proposes a kind of gas fire-fighting controller, the safety coefficient of whole blower fan can be improved, save cabinet space, do not affect Electro Magnetic Compatibility, guarantee that controller normally runs at blower interior.
For reaching this object, the present invention by the following technical solutions:
A kind of gas fire-fighting controller, be applicable to Wind turbines, comprise core control devices and 8 loop apparatus, each loop apparatus comprises the port-guard module of data processing module, feedback information input module, command output module, panel command reception module, communication module and correspondence, wherein feedback information input module, command output module, panel command reception module and communication module respectively with corresponding port-guard model calling, described port-guard module be used for port-guard is carried out to the input/output signal of place loop apparatus.
Preferably, described loop apparatus comprises two independent sectors, and described port-guard module is positioned on an interface board, and other parts of described loop apparatus are positioned on a circuit board.
Preferably, be connected by connecting line between described interface board with described circuit board.
Preferably, be connected by connector between described interface board with described circuit board.
Preferably, described interface board is put with described circuit board is overlapping in space, is positioned at cabinet inside.
Preferably, described port-guard module comprises common mode inductance, TVS and XY electric capacity further.
Technical Design of the present invention has the gas fire-fighting controller of 8 loop apparatus, can ensure that each independent zone of protection of blower interior can be assigned to a loop, improves the safety coefficient of whole blower fan; Under the prerequisite not increasing gas fire-fighting controller volume, divide plate to design the signal processing of circuit units and port-guard part, spatially overlappingly can place, save cabinet space, do not affect Electro Magnetic Compatibility, guarantee that gas fire-fighting controller normally runs at blower interior.
