automatic tracking arc suppression coil compensation device
Automatic tracking arc suppression coil compensation device applies the automatic tracking arc suppression coil compensation technology and supporting single phase earthing computer line section technology. The complete device includes neutrality poit isolation switch, Z-type earthing transformer, adjustable capacity arc suppression coil, damping pressure limiting resistance box, and controller. The earthing transformers is used in the unearthing system of the neutrality point, and to lead the neutrality point; adjustable capacity arc suppression coil is the core inductor coil with secondary winding supply the emotional current for the system. Impregnation wrapping arc suppression coil has the features of good cooling, no need of die and flexible design.

- 1、low noise, high energy-saving. The core applies high permeability cold rolled grain oriented silicon steel, three step lap, 45 degree fully inclined joint form, no punched hole, and thus reduced the technology loss and no-load loss, and it applies the international first-class automated shear line, hill-type folding equipment molding at the first time, and therefore reduce the noise problem of the core structure. 2、Flexible design, prompt delivery. The production of the products is not affected by the die, and the production cycle of the non-standard products can shorten five or more days. 3、Good cooling system. The HV and LV coil applies the multi airflue structure and therefore they are of good cooling. The products does not need the forced ONAF, can run safely under the electricity peak load of 120% circumstance. 4、Hign mechanical strength of the coil and high ability withstanding impulse. The HV coil after several times of vacuum pressure impregnation, baking, and therefore has the features of high mechanical strength of solid coil and can withstand the severe external force and instant current inpact. 5、High grade heat-resistant insulation. The main components material heat-resistant temperature is of 180 degrees (H class), and the core part applies the Dupont NOMEX paper of the United States as the insulation medium (HV, LV coil) heat-resistant temperature is of 220 degree (C class). 6、Green, environment-protection. HV and LV coil does not support combustion, and does not release the toxic gases, and the main materail can be decompositioned recovery after the service life. 7、Dust-proof, moisture-proof, strong ability of anti-pollution. It applies the special coil impregnation technology, and therefore the transformer is of good dust-proof, moisture-proof, and anti-pollution, and it can be used in all kinds of adverse circumstance, and can transmiss the power successfully one time under the 95% humidity. 8、The controller includes singlechip, signal acquisition conversion systems, liquid crystal displays, relay, vacuum contacts, capcitors and so on. It has the function of automatic print of the moitoring record, and the features of accurancy counting of capacitant current, high effeciency of compensation current, accurancy fault line choice, reliable operation, its technology is on the leading place in the State.
