Description of drawings
Fig. 1 is the structural scheme of mechanism of generator of the present invention.
Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, does detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention, it will be more clear making above-mentioned and other purpose, characteristic and advantage of the present invention.Reference character identical in whole accompanying drawings is indicated identical part.Painstakingly do not draw accompanying drawing in proportion, focus on illustrating purport of the present invention.
Be illustrated in figure 1 as wind-driven generator of the present invention, it has comprised generator main body 1, and this generator main body has comprised intake grill 9 and exhaust outlet 10, wherein is provided with ozone sensor in the exhaust outlet position.The present invention utilizes the ozoniferous characteristic gas of generator local discharge; The place is provided with the ozone detecting sensor at the generator exhaust outlet; Process is confirmed the partial discharge state strength that generator is in operation to the detection of ozone concentration, thereby generator insulating is effectively monitored.With respect to traditional detection method for local discharge, ozone detects not to be needed to shut down, easy for installation, detection sensitivity is high, the characteristics that expense is low, can carry out the generator local discharge monitoring constantly.Its working principle is: the intensity of local discharge signal can directly reflect the situation of generator insulating system; Can produce ozone gas during generator local discharge; The present invention can judge generator local discharge intensity through detecting concentration of ozone gas; Effectively reflect the generator insulating state, master control shows, reports to the police and stores.
In the present embodiment; Be provided with two ozone sensors 3,4 in exhaust outlet 10 positions; The signaling line of ozone sensor and power line are electrically connected in the master control cabinet 2; For example, the power line of ozone sensor meets the DC24V of master control cabinet, and the signaling line of ozone sensor connects the analog amount interface of the WP351 module of master control cabinet PLC.But those skilled in the art should be appreciated that, the invention is not restricted to two, all can more than one or two.Plural ozone sensor can be monitored ozone content multi-faceted, more fast accurately.Control ozone sensor through master control cabinet 2, and the signal of ozone sensor is handled.After the sensor energize testing signal is sent to the master control cabinet, the master control cabinet is judged the generator insulating state through the signal of gathering.
Preferred, in the present embodiment, the signaling line of ozone sensor and power line are received in the generator auxiliary connection box 5, are electrically connected in the master control cabinet through auxiliary connection box 5.As shown in the figure, the signaling line of the signaling line of ozone sensor 3 and power line 6 and ozone sensor 4 and power line 7 are connected respectively in the auxiliary connection box 5, are connected on the master control cabinet 2 through connecting line 8 again.
When work; To corresponding autotest of primary control program compiling; And set 3 thresholdings; The master control meeting was sent and is preserved a guard sign and gives central control chamber when master control received current signal greater than the 1st thresholding, required next staff to march into the arena and when safeguarding generator insulating was checked and safeguarded; Master control can be sent and preserve a guard sign equally and given central control chamber when master control received current signal greater than the 2nd thresholding, required in a week, to on-the-spot generator insulating to be carried out remedial measure; Halt instruction was sent in the master control meeting when master control received current signal greater than the 3rd thresholding, and sent a failure code and inform the shutdown reason to central control chamber.Described preceding two thresholding blower fans normally move, and described the 3rd thresholding fan trouble shut down regulation and after the isolation layer reparation of generator infringement is good, can be started shooting.
In above description, a lot of details have been set forth so that make much of the present invention.But above description only is preferred embodiment of the present invention, and the present invention can implement much to be different from alternate manner described here, so the present invention does not receive the restriction of top disclosed practical implementation.Any skilled personnel are not breaking away under the technological scheme scope situation of the present invention simultaneously; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to technological scheme of the present invention, or are revised as the equivalent embodiment of equivalent variations.Every content that does not break away from technological scheme of the present invention to any simple modification, equivalent variations and modification that above embodiment did, all still belongs to technology of the present invention according to technical spirit of the present invention.
