FAQ
Q： What is a SF6 circuit breaker?
A：
An SF6 circuit breaker is a type of high-voltage circuit breaker that uses sulfur hexafluoride (SF6) gas as the arc extinguishing and insulating medium. It can safely interrupt electrical current and isolate electrical circuits.
Q： What is SF6 used for?
A：
SF6 (sulfur hexafluoride) is mainly used as an arc extinguishing and insulating medium in high-voltage electrical equipment like circuit breakers, switchgear, and transformers. It's also used in some types of high-voltage transmission and distribution systems, and in some industries for leak detection and as a tracer gas due to its stability and unique properties.

As a front - line fault maintenance worker, I deal with current transformers (CTs) daily. A CT’s secondary winding in operation must never open - circuit! Once open - circuited, the secondary current and demagnetizing potential vanish. All primary - side magnetic potential then becomes the iron core’s exciting potential, sharply increasing its magnetic flux density. High voltage on the secondary side will endanger safety anytime.Despite strict power operation regulations, user electr

What are the causes of current transformer faults and the countermeasures for faults?
As a front - line maintenance technician, I deal with current transformers (CTs) daily. CTs convert high - magnitude primary current to low - magnitude secondary current for substation/line protection and measurement, operating in series long - term. However, they face faults from external (unbalanced loads, wrong wiring, etc.) and internal (insulation defects) issues. These faults, like secondary open - circuits or insulation breakdown, harm measurement accuracy, protection operation, and grid

Automatic backup switching (ABTS) devices are core components ensuring the safe, reliable, and stable operation of factory power grids. Their startup logic strictly follows the dual criteria of "loss of voltage in the working power supply + no - current detection", effectively avoiding misjudgments caused by secondary disconnection of voltage transformers (VTs) or maloperations of ABTS due to secondary circuit faults of current transformers (CTs).
