Abstract
The invention relates to an interlocking testing method for a standby boiler of a protection device. The interlocking testing method comprises the following steps: pre-adjusting the opening degree of the device participating in interlocking testing and enabling the device participating in the interlocking testing to have no charge so as to prevent damage and harm to the related testing device during interlocking bumping testing of the boiler. An operation method of the protection device disclosed by the invention is suitable for protection of power equipment, and devices and facilities thereof, which have interlocking protection devices and need to perform periodical interlocking testing (static or dynamic interlocking testing) according to provisions of laws and regulations. The method disclosed by the invention is conductive to not only rapid interlocking testing of the standby boiler, but also protection of the devices participating in testing during the interlocking testing process.
Description
Technical field
The present invention relates to the stand-by boiler interlock test method of a kind of protection equipment (boiler accessory machinery).
Background technology
Relevant " rules " regulation, the safety attachment of every boiler and interlocking protective device are wanted periodic maintenance and test, to guarantee its sensitivity, reliable.In order to guarantee the safe and reliable of stand-by boiler and to close rule use, regularly to do per month the interlocking jumping car test (unplanned emergency lift stokehold also must be done) of stand-by boiler, because the stand-by boiler back-up period is longer, the frequency of therefore doing interlock test is also more.No matter be to do the Static and dynamic interlock test, the 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 (being widely used), when stand-by boiler is done regular interlocking jumping car test, need to restart after the interlock of fan stop jumping, and this moment, blower fan stop jumping rear fan shaft coupling was still at high-speed cruising, need generally speaking to wait for that blower fan stops just to restart afterwards, otherwise when can not stop fully because of blower fan, produce a back electromotive force, cause the tripping operation of frequency converter overload, cause the serviceable life that the damage of blower fan is reduced blower fan because of the tripping operation of fan frequency converter overload simultaneously, Frequent Troubles causes restarting the operation frequency when increasing the test of interlocking jumping car.
Summary of the invention
The stand-by boiler interlock test method that the purpose of this invention is to provide a kind of protection equipment (boiler accessory machinery) simple to operation; the method of operating of this protection equipment (boiler accessory machinery) is good by the practical application verification the verifying results; both be conducive to the stand-by boiler interlock test and tested rapidly, be conducive to again the equipment that the protection of interlock test process participates in test.
When doing the stand-by boiler interlock test, feed back the interlocking pre-set parameter with the circuit signal source, irrelevant with fans load, only need the startup blower fan to participate in test and get final product.
When the present invention is achieved in that the regular interlock test of stand-by boiler, participate in the aperture of interlock test equipment by adjusting in advance (can on the spot or program control adjustment), the equipment that order participates in interlock test is on-load not, when avoiding the stand-by boiler interlocking to jump the car test to damage and the infringement of correlation test equipment.
When doing the stand-by boiler interlock test, the induced draft fan aperture is adjusted into " 0 ", it is " 0 " that pressure fan, fire grate, feeder are adjusted aperture, stack damper is opened 10% and is carried out regular interlock test, be not on-load of pressure fan, induced draft fan, fire grate, feeder, in the time of so just can avoiding doing the stand-by boiler interlocking and jump the car test to damage or the infringement of correlation test equipment.
The present invention is applicable to power-equipment and the device that (relevant " rules " regulation) possesses interlocking protective device and need carry out regular interlock test (static or dynamic interlock test).Method of operating of the present invention is good by the practical application verification the verifying results, both has been conducive to the 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.
Description of drawings
Fig. 1 is the stand-by boiler interlock test method of operating schematic diagram of protection equipment of the present invention.
Among the 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 the interlocking direction successively on the spot or program control adjustment participate in the aperture of interlock test equipment, specifically be adjusted into boiler induced-draft fan (1) aperture and be " 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 setting of the participation interlock test equipment when finishing stand-by boiler and regularly interlocking, stack damper are opened 10% and are carried out regular interlock test.Like this, to damage and the infringement of correlation test equipment, reach the purpose of protection interlock test system and correlation test equipment in the time of can avoiding the stand-by boiler interlocking to jump the car test.
Claims (2)
1. stand-by boiler interlock test method of protecting equipment; it is characterized in that by adjusting in advance the aperture that participates in interlock test equipment; the equipment that order participates in interlock test is on-load not, when avoiding the stand-by boiler interlocking to jump the car test to damage and the infringement of correlation test equipment.
2. the stand-by boiler interlock test method of protection equipment according to claim 1; it is characterized in that when doing the stand-by boiler interlock test, the induced draft fan aperture being adjusted into " 0 "; it is " 0 " that pressure fan, fire grate, feeder are adjusted aperture; be not on-load of pressure fan, induced draft fan, fire grate, feeder, stack damper is opened 10% and is carried out regular interlock test.
