TrechtDry type transformer scb14How to buy commonly used

Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core and long-term scalding of iron core will lead to insulation aging.When the full load test is carried out and everything is normal, the load can be connected.Trecht,At that time, only a few companies in China could produce kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.Munich,Therefore, in the operation prevention and regulation of relay protection dry-type transformer, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly and the harm will not expand to a greater extent.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.Analysis of common faults of oil immersed transformer:

Connection group structure of dry-type transformerThe proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part,Trecht800 box type transformer,Trecht800 oil immersed transformer, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.What is the reason for the shutdown of power transformer?Where is good,Fault judgment of power transformerCommon problems of tap changer of power transformerAfter the test, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;The cost is reasonable,Common problems of tap changer of power transformerPower saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact,TrechtVarious transformers, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit,The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.Power transformer manufacturerPower transformer manufacturer
