Dry Distribution Transformer Capacity

There are many models and specifications of dry distribution transformer. Different types and specifications of dry-type transformers have different applications, different characteristics, and different capacities. Tips for selecting dry distribution transformer capacity.

First of all, it is necessary to carry out research on the power supply voltage of the specific power consumption site, comprehensively analyze the specific power consumption of the customer and the standards of the region, and then select one by one referring to the technical data information on the factory nameplate of the transformer. Generally, it is necessary to select from the transformer capacity, work The voltage, current and natural environment standards are comprehensively considered, and the volume selection should be based on the volume, characteristics and use time of the customers electricity consumption equipment to determine the required load. For this reason, the dry-type transformer capacity is selected.

Secondly, in the whole process of the normal operation of the dry distribution transformer, the power consumption of the dry-type transformer should be about 75-90% of the short-circuit capacity of the dry-type transformer. At 50%, the small-volume transformer should be replaced. If the short-circuit capacity of the transformer is lower than the transformers short-circuit capacity, the large transformer should be replaced immediately.

Naturally, the route switching power supply determines the working voltage value of the primary coil of the dry distribution transformer, and selects the working voltage value of the secondary coil according to the power consumption equipment, preferably the bottom voltage three-phase four-wire power supply system. In this way, the power consumption of driving force and general lighting power can be displayed separately.

The selection of dry distribution transformer capacity should be carried out in a comprehensive manner as far as possible. Only in this way can it be ensured that the transformer products that can consider specific requirements can be selected.
