Description
Technical field
The invention belongs to transformer noise technical field of measuring equipment, and in particular to a kind of 10kV distribution transformer noise survey
Measure device and its measurement method.
Background technique
In recent years, distribution transformer had been increasingly appearing in residential quarter and public place, and distribution transformer is made an uproar
Sound is increasingly becoming environmentally friendly new problem concerned by people.Distribution transformer needs to carry out sound level test, detector in sampling Detection
Noise level, to determine if to meet relevant criterion requirement.
Transformer noise is generated by the vibration of iron core, winding, fuel tank and cooling device.And transformer body noise
Size, it is related with the factors such as the magnetic flux density of iron core when the rated capacity of transformer, the performance of silicon steel sheet and rated no-load.Separately
Outside, when transformer load is higher or external environment temperature is higher, in order to reinforce the cooling effect of transformer, Self-cooling transformer
Oil can be recycled in cooling fin, this process can also generate noise.
According to the requirement of " the 10th part of power transformer: sound level measurement " GB/T 1094.10-2003: making an uproar to transformer
When sound measures, for transformer of the fuel tank height less than 2.5m, it is specified that contour line should be located at the level at fuel tank height 1/2
On face, under the conditions of air cooling equipment (if there is) is out of service carry out sound level measurement when, it is specified that contour line should be sent out away from benchmark
Face 0.3m is penetrated, the microphone of noise measuring set should do the movement for being similar to even speed on the defined outline line around test product.
Currently, the sound level test of distribution transformer detects, or using conventional main transformer noise measuring method.It is logical
It crosses survey crew and holds integral type sound level meter, the measuring probe of sound level meter is extended into noise testing desired position and is surveyed
Amount.But this measurement method has Danger Electric shock risk.
Because the fuel tank height of usual 10kV distribution transforming only has 0.8m or so.When no-load test, low-pressure side applies voltage rating
400V, on high-tension side voltage can then reach 10kV.According to GB 26860-2011 " electric power safety working regulation power plant and power transformation
Stand electric part " regulation, when equipment does not have a power failure, 10kV and safe distance below are 0.70m.Distribution transforming noise testing usually exists
Spacious test room floor carries out, and the high-pressure side 10kV casing height is about 0.3m, in addition fuel tank height, total height is about
1.1m.At this time, testing crew is when carrying out height 0.4m, noise testing from transformer case horizontal distance 0.3m, hence it is evident that
It is unsatisfactory for the requirement of " electric power safety working regulation power plant and substation's electric part " safe distance, there is Danger Electric shock risk.
