(1) deterministic process of the empirical parameter error that will inevitably induce one;
(2), if the machine performance of isolating switch changes, empirical parameter will be difficult to accurately reflect the just minute moment that closes of contact.
What the contact of isolating switch generally adopted is similar dull and stereotyped dock structure, in the collision meeting that closes moment dynamic/static contact, on isolating switch surface, produces strong vibration, therefore can determine on-off time by the vibration signal in monitoring breaker making process.Sub-switching operation does not have contact collision accident, but dynamic/static contact is in firm minute moment, and due to the self-closing power overcoming from arc-chutes, motion connecting portion produces strong friction, adds the influence factors such as arc noise, on gear train, also can produce certain vibration.Test discovery, the vibration that the amplitude of separating brake vibration produces than the collision of closing a floodgate is little.Because used vibration transducer sensitivity is very high, so still can collect separating brake vibration signal in place, with this, reflect the just minute moment of contact.In test, vibration transducer is arranged on to the bottom of the insulated tension pole close to from moving contact.
The mode 1 of above-mentioned employing, determines that an empirical parameter has just divided constantly as contact closing, exists very large error in practical operation; Mode 2, relies on vibration signal to detect accurately, but data acquisition and analyzing and processing more complicated, sensor precision prescribed is high, and whole equipment cost is high.
