ENTF-S
ENTF-S Dynamic thyristor switching switch
产品概述:
ENTF-S dynamic thyristor switching switch is a high-power dynamic fast compensation switching switch specially designed for power capacitors with voltage levels of 0.69kv and below. It has fast follow-up speed and response time of 10-20 milliseconds. It is mainly applicable to impact loads and electrical loads requiring rapid switching of capacitors, such as electric welding machine, steel rolling, port crane, elevator, frequency conversion furnace and other occasions in line with rapid changes.
产品特点:
The pre charging mode is adopted, and the next round of switching can be carried out without waiting for the completion of capacitor discharge, so as to truly realize the high-speed switching of less than 20ms;
Reasonable structural design, simple wiring and convenient installation and commissioning;
An effective protection circuit is adopted to improve the anti harmonic ability of the regulator;
The variable frequency speed regulating fan with temperature controller can reliably ensure that the thyristor works within the specified temperature range, with a service life of more than 100000 hours and maintenance free;
It can be controlled by DC12V input or by communication;
Input when the voltage difference is zero and cut off when the current is zero to ensure that there is no inrush current;
Make full use of integrated circuits, reduce discrete components as much as possible, make the switch volume as reasonable and as small as possible, and reduce the cost of the whole cabinet; The anti-interference circuit design improves the anti-interference ability of the switch, effectively prevents the thyristor breakdown fault caused by false triggering, and has passed the four-level standard of EMC test;
It can detect the operating temperature of the switch and upload the temperature status through communication;
It has the functions of undervoltage, overtemperature and phase loss protection.
