Product Description

product description

SG-F series imported equipment supporting three-phase dry-type isolation transformer is a new generation of energy-saving power transformer developed and produced by our factory on the basis of referring to similar products and combining my country's national conditions. The winding adopts the method of unfinished and whole-column winding; the transformer is vacuum dipped, so that the insulation level of the transformer can reach the F level or H level, and the product performance has reached the advanced level at home and abroad. SG-F series three-phase dry-type isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltage below 3300V. . The various input and output voltage levels of the product, the connection group, the number and position of the adjustment taps (generally ±5%), the distribution of the winding capacity, the configuration of the secondary single-phase winding, the use of the rectifier circuit, whether the belt is required Shells, etc., can be carefully designed and manufactured according to user requirements.

Features

Establishing a new neutral line-grounding in the isolation transformer can relieve the common mode interference of the power grid and the troubles of other neutral lines. The isolation transformer converts the three-wire △ connection into a four-wire Yo system, and the shielding further eliminates the high-frequency pulse interference coupled by the transformer. Although the shielded isolation transformer can effectively prevent interference from various NGs (pulse and high-frequency noise), the transformer must be properly grounded and very strict, otherwise the anti-common mode interference will be ineffective. The company can design and produce high-quality isolation transformers for customers.

Features advantages:

ØHigh isolation

ØN-G has good performance

ØHigh common mode interference rejection

Ø Convert △ to Y or Y to △

Ø Voltage taps are easy to change

ØDesigned according to the special performance requirements of users
