According to SCB13-80KVA Dry type transformer Typical design requirements, as station power and lighting needs, must set up station transformer. Low loss Dry type transformer The Department is specially designed for SCB13-80KVA. Dry type transformer Matching design. The special structure is adopted to optimize the design of the external dimensions under the premise of meeting the requirements of various performance parameters of the standard. It fully meets the installation requirements of dry type transformers and is an ideal matching transformer for SCB13-80KVA dry type transformers. The SCB13-80KVA dry type transformer transformer with low loss is directly charged from the bus side on the primary side, and there is usually a winding on the two side (0.4KV is used for electricity and lighting in the station. According to customer requirements, the two side can add a group of winding (0.1KV, 50VA for station equipment measurement, control and protection.

SCB13-80KVA dry type transformer features:
The 1. coil is made of copper wire winding or foil winding, the non-woven fabric film is used as raw material, and the non-woven fabric film has relatively thin insulation thickness and high voltage resistance. It is an ideal winding material for small size, high output and high reliability electrical products. High pressure resistant, epoxy resin without filler, vacuum drying degassing and dewetting, integral pouring, high mechanical strength, short circuit resistance and strong impact resistance.
2. the end of the high voltage winding and the intermediate tap are embedded with copper inserts, which are of good steel property and easy to adjust, and are beautiful and neat.
3. the core is made of 120 new cold rolled silicon steel sheet and 45 degree inclined multi step joint. The surface is covered with resin insulating coating, which is moisture resistant, rust proof and noise reducing.
4. the iron core, clamping parts and coils are clamped by elastic parts, so that the coil is in a stable compacting state to reduce noise.
The 5.SCB13-80KVA dry type transformer is designed according to the self cooling design. The longitudinal ventilation channel is reserved in the wall of the integral high (low) pressure coil housing, which can be equipped with forced air cooling device (cooling fan). The forced air cooling device can increase the output capacity by 20%.
6. equipped with thermostat, platinum resistance (PtlOO) is placed in the embedded hole at the top of the low-voltage coil. In order to monitor the temperature rise of transformer winding, it can automatically start and stop the cooling fan, and has the function of fault alarm, over temperature alarm and over temperature trip, providing reliable overload protection device for dry type transformer, so as to improve the safety of dry type transformer operation.
