Specific embodiment
Embodiment one：
A kind of isolator detecting equipment, including water filling device 1, detection probe 2, processing unit 3, display module 4, the water filling dress
It puts 1 to connect with detection probe 2, the detection probe 2 is electrically connected with processing unit 3, the processing unit 3 and 4 electricity of display module
Connection, the detection probe 2 are internally provided with electrode 21, and the processing unit 3 calculates insulator according to the information that electrode 21 acquires
Equivalent salt density, and pass through display module 4 and show.
When the detection probe 2 is arranged on 7 surface of insulator, housing bottom forms cavity 24, and the electrode 21 is located at shell
In vivo, the detection probe housing 25 is in double-layer structure, and housing bottom 251 is made of flexible material and is open in horn-like,
The flexible material is pressurized after discharge gas in negative pressure state, described so as to firmly adsorb detection probe on 7 surface of insulator
Cavity 24 is used for the ionized water that water filling device is received to inject.
Heating element 22 and temperature sensor 23 are equipped in cavity 24, the heating element is opposite with temperature sensor to be set
It puts.Perturbations 5 are additionally provided in cavity 25, the perturbations 5 are arranged on the side wall of cavity, and perturbations 5 include blade 51
And the motor 52 being connect with blade, the perturbations are set close to the heating element.When detection probe is fixed to insulation
Behind sublist face, water filling device injects ionized water into cavity, and then heating element 22 heats ionized water so that insulator
Filthy accelerate dissolving, while temperature sensor detection water temperature, while perturbations 5 start to act, and on the one hand further speed up
Filth dissolving, on the other hand hands over the higher temperature water added near element with lower temperature water near temperature sensor
It changes, by the detection of water movement water temperature more evenly, the rotating speed of the blade 51 is 30 revolutions per seconds.
In order to enable the data of detection are more accurate, insulator is first divided into n region, detection probe choosing in the present embodiment
One of region is selected, and insulator surface is fixed in the region.

Value maintains the constant temperature 15 seconds to 50 DEG C；
By the conductivity of electrode measurement solution, then according to the salt density Pi of Conductivity Calculation solution, insulation is determined through converting
The filthy situation in the sub region；
Then other regions are replaced, finishes until each region of insulator is detected and preserves testing result.
Then processing unit 3 calculates the equivalent salt density of insulator according to formula
This programme is by the way that directly the filthy of each region of dissolving insulator forms solution at the scene, you can effectively determines insulator
Filthy situation, it is filthy due to not being related to the wiping of intermediary substance, detection data is more accurate.
In most cases, the filth of insulator surface is relatively uniform, but is also not excluded for non-uniform situation occur, because
This in this embodiment, also adds the judgement that local filth causes insulator to fail, i.e., whether the more local close Pi of salt is more than
5P, more than then there are local risk, otherwise it is assumed that devoid of risk.
This programme passes through the direct filthy situation in detection insulator each region at the scene, you can effectively judges the whole of insulator
Body situation, since the intermediary's substance wiping do not given up is filthy, detection data is more accurate.
The detection device further includes radio transmission elements 6, by the pollution level, detection time and location transmission of detection
It is stored to remote center, and forms the pollution level curve that each insulator changes over time, then prediction needs the time safeguarded.
It is stored by sending data to remote center, not only can effectively determine the state when front insulator, Er Qieke
It is changed with time situation with further reacting the insulator, according to its time for breaking down of the information prediction of big data, done
To timely prevention.
