31500KVA oil-immersed transformer

Product description

The 31500KVA oil-immersed transformer independently developed by the company is an environmentally friendly distribution transformer, which has two sizes and two types of fixed capacity and two types of smooth capacity, and the operation mode can be automatically converted. It solves the problem that the periodic load change range of the 1OkV distribution network is relatively large and leads to large transformer consumption, and overcomes the problem of operation and maintenance caused by the manual adjustment of the volume of the transformer without load capacity regulation. Compared with the selection of two sub-mother transformers, the selection of S11(13)-M-ZT on-load capacitance transformer reduces the cost of equipment purchase and installation, and the space is reduced, the construction period is reduced, and the operation and maintenance workload is significantly reduced.

Fields of application

The 31500KVA oil-immersed transformer is not only suitable for rural power grids with large periodic load changes, but also for some urban commercial areas, development zones, industrial zones and other radio stations with significant day and night load changes.

Technical characteristics

1. The engineering economic performance is good, and the product can greatly reduce the no-load loss of the transformer by 50-60% and the reactive power loss of the power grid by 20-30%.

2. Spiral coil with vertical oil duct, better internal heat dissipation; The efficient support of the coil end face has been improved, and the capacity of the short circuit resistance is very strong.

3. The shell adopts the sealed structure of corrugated oil tank to avoid contact between gas, moisture and transformer oil, which reduces the aging level of oil and prolongs the service life of the transformer; According to the elastic deformation of the corrugated sheet, the volume transformation of transformer oil expansion and cold contraction is adjusted.

4. The product is an outdoor structure, with high pollution resistance level and good heat discharge; There is no need to replace the transformer oil during the normal service period, reducing maintenance and ensuring the safe operation and stability of the power grid.

5. The transformer is equipped with a pressure release safety protection device, when the transformer fault pressure is too high, it can be reliably and safely released through the pressure release valve to avoid the expansion of the accident.
