According to the volt-microsecond product ∫udt and the frequency fp of the trigger pulse, the volt-microsecond product of the known trigger pulse should be less than or equal to the rated volt-microsecond product of the KCB trigger transformer in the frequency range.
This is a kind of high voltage fully enclosed thyristor trigger transformer with excellent performance and structure. It has the characteristics of small size and compact structure, but its most significant feature is high electrical resistance, especially suitable for the use of thyristor control circuits with high operating voltage.
Features
① Totally-encapsulated printed circuit board being able to be directly welded and assembled;
② High capability of mechanical and environmental isolation, compact in structure, solid, vibration-proof, moisture-proof and flame-resistance;
③ High dielectric strength between coils;
④ Ratio can be changed by customers to meet the requirement for triggering;
⑤ Able to match thyristors of all capacities;
⑥ Able to be used as common pulse transformers
Applications
The triggering transformer is used with thyristor. It is commonly connected in between controlled triggering unit and controlling grid of thyristor to transfer triggering pulse in thyristor equipment; and acts as a reliable isolator between high and low voltages. KCB Series triggering transformers can be used for the following equipment:
① Voltage and speed controlled equipment;
② Electric welding machine;
③ Elevator;
④ Power supply with intermediate frequency;
⑤ Rectifier;
⑥ Inverter frequency converter;
⑦ Self-controlled device;
⑧ Other thyristor device.
