FAQs
What is the primary purpose of a Switch Dynamic Characteristics Test Set?
A: To ensure the reliable operation of power systems by analyzing the mechanical health of circuit breakers. It detects faults like wear, aging, or misalignment before they cause failures.
What key parameters does it measure?
A: It measures critical time, speed, and displacement in a single test. This includes opening/closing time, bounce time, contact speed, stroke, over-travel, and coil current.
Why is “bounce time” a critical measurement?
A: Excessive bounce signals mechanical instability that could lead to contact erosion or arc reignition. High bounce values indicate worn components, risking damage to the switch and system failure.
What are the main features of modern test sets?
A: Modern test sets are portable, integrated, and “intelligent,” featuring all-in-one testing, on-site capabilities, and anti-interference design. Future units will leverage AI for predictive maintenance and smarter defect detection.
