Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

Dry type transformer

Mendoza.With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.

The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the load can be reduced or the operation of the transformer can be stopped.

When leaving the factory,Mendoza500 KVA oil immersed transformer, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.

Brief introduction of zero line of power transformer

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name,MendozaDistribution rectifier transformer, source, sampling date, sampling person, weather conditions and other materials of the oil sample.

Dry type transformer, a static electrical equipment, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the 29 kinds of dry-type transformer commodities manufactured by 29 manufacturers in 12 provinces and municipal districts across the country,MendozaInternal structure diagram of oil immersed transformer, 6 kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of 80%& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible so as to reduce the electric field component intersecting with the insulating parts.

reform.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by 1000V megger, the resistance value exceeds 2m ohm bus.

Protection mode for type selection of dry-type test transformer

Wiring mode of dry-type transformer:

Mendoza.In specific daily life we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

Noise solution of dry-type transformer

When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
