Abstract
The present invention is a kind of stand-by boiler interlock test method of proterctive equipment.By adjusting the aperture of participation interlock test equipment in advance, order participates in the equipment not on-load of interlock test, avoids stand-by boiler to interlock and jumps when car is tested the damage of correlation test equipment and infringement.What the method for operating of proterctive equipment of the present invention was applicable to that " regulation " specify possess interlocking protective device and need carry out the power-equipment of regular interlock test (static or dynamically interlock test) and the protection of device and equipment thereof.Method of the present invention had both been conducive to stand-by boiler interlock test and had tested rapidly, was conducive to again the equipment that the protection of interlock test process participates in test.
Description
Technical field
The present invention relates to the stand-by boiler interlock test method of a kind of proterctive equipment (boiler accessory machinery).
Background technology
Relevant " regulation " regulation, safety attachment and the interlocking protective device of every platform boiler want periodic maintenance and test, to ensure that it is sensitive, reliable.In order to ensure the safe and reliable of stand-by boiler and close rule use, car test (also must do before unplanned urgent kindling) jumped by the interlocking that monthly regularly will do stand-by boiler, and because stand-by boiler back-up period is longer, the frequency therefore doing interlock test is also more.No matter be do Static and dynamic interlock test, interlock test condition: induced draft fan, pressure fan, fire grate, feeder should stop in automatic trip when arbitrary parameter arrives interlocking jumping car parameter.If but boiler induced-draft fan and pressure fan adopt frequency conversion fan (widely using), when stand-by boiler does regularly interlocking jumping car test, need to restart after interlock of fan stop jumping, and now blower fan stop jumping rear fan shaft coupling still at high-speed cruising, generally need to wait for that blower fan just can restart after stopping, otherwise can because of blower fan do not stop completely time, produce a back electromotive force, frequency converter overload is caused to trip, simultaneously because the tripping operation of fan frequency converter overload causes the serviceable life of the damage of blower fan being reduced to blower fan, Frequent Troubles, cause restarting increasing when car test jumped by interlocking and operate the frequency.
Summary of the invention
The object of this invention is to provide a kind of stand-by boiler interlock test method of proterctive equipment simple to operation (boiler accessory machinery); the method of operating of this proterctive equipment (boiler accessory machinery) is good by practical application verification the verifying results; both be conducive to stand-by boiler interlock test to test rapidly, be conducive to again the equipment that the protection of interlock test process participates in test.
When doing stand-by boiler interlock test, with circuit signal source feedback interlocking pre-set parameter, have nothing to do with fans load, only need to start blower fan and participate in testing.
When the present invention is achieved in that stand-by boiler regular interlock test, by adjusting the aperture that (can on the spot or program control adjustment) participates in interlock test equipment in advance, order participates in the equipment not on-load of interlock test, avoids stand-by boiler to interlock and jumps when car is tested the damage of correlation test equipment and infringement.
When doing stand-by boiler interlock test, induced draft fan aperture is adjusted to " 0 ", pressure fan, fire grate, feeder adjustment aperture is " 0 ", stack damper is opened 10% and is carried out regular interlock test, i.e. pressure fan, induced draft fan, fire grate, feeder not on-load, so just can avoid making stand-by boiler interlocking and jump when car is tested the damage of correlation test equipment or infringement.
The present invention is applicable to (relevant " regulation " specify) possesses interlocking protective device and need carry out power-equipment and the device of regular interlock test (static or dynamically interlock test).Method of operating of the present invention is good by practical application verification the verifying results, has both been conducive to stand-by boiler interlock test and has tested rapidly, is conducive to again the equipment that the protection of interlock test process participates in test.
Accompanying drawing explanation
Fig. 1 is the stand-by boiler interlock test method of operating schematic diagram of proterctive equipment of the present invention.
In figure, 1-boiler induced-draft fan, 2-boiler fan, 3-boiler grate motor, 4-coal feeder of boiler.
Embodiment
As shown in Figure 1, when stand-by boiler is regularly interlocked, by interlocking direction successively on the spot or program control adjustment participate in the aperture of interlock test equipment, specifically be adjusted to boiler induced-draft fan (1) aperture for " 0 ", boiler fan (2) aperture is " 0 ", and boiler grate motor (3) aperture is " 0 ", and coal feeder of boiler (4) aperture is " 0 ", the aperture adjustment completing participation interlock test equipment when stand-by boiler is regularly interlocked is arranged, and stack damper is opened 10% and carried out regular interlock test.Like this, to the damage of correlation test equipment and infringement when stand-by boiler interlocking jumping car can be avoided to test, the object of protection interlock test system and correlation test equipment is reached.
Claims (2)
1. the stand-by boiler interlock test method of a proterctive equipment; it is characterized in that by adjusting the aperture participating in interlock test equipment in advance; order participate in interlock test equipment not on-load carry out interlock test again; to the damage and the infringement that participate in interlock test equipment when avoiding stand-by boiler interlock test, the equipment of described participation interlock test is pressure fan, induced draft fan, fire grate, feeder.
2. the stand-by boiler interlock test method of proterctive equipment according to claim 1; it is characterized in that when doing stand-by boiler interlock test, induced draft fan aperture being adjusted to " 0 "; pressure fan, fire grate, feeder adjustment aperture is " 0 "; i.e. pressure fan, induced draft fan, fire grate, feeder not on-load, stack damper is opened 10% and is carried out regular interlock test.
