It is suitable for the setting range during startup: 0.5~30A 2~8 times of the overcurrent setting value is more than 2~6 times of the 40A overcurrent setting value until 60A 2 to 4 times the current setting value 0.5 seconds after D-Time Stall This value is set to a multiple of the overcurrent set value. It is suitable for the setting range during operation: 1.5~5 times of 0.5~50A overcurrent setting value up to 1.5~4 times of 60A overcurrent setting value. Adjustable from 0.2 to 5 seconds Missing phase The maximum phase imbalance ratio of the three-phase current exceeds 85% (OFF/ON) OFF, adjustable from 0.5 to 5 seconds Reverse phase The phase sequence of the three-phase current is not reciprocal (OFF/ON) OFF, within 0.15 seconds Current imbalance Current imbalance rate = (maximum phase current - minimum phase current) / maximum phase current × 100% Current imbalance rate ≥ set current imbalance rate setting range: 10~50% Adjustable from 1 to 10 seconds Ground Exceeding the setting ground current value setting range: OFF, 0.03~10A Adjustable from 0.05 to 10 seconds

Wooden Sleeper

Railroad construction wooden sleeper characteristics
Wooden sleepers ,also called Pinus Sylvestris Wooden Tie,Rail Wood Ties,Rail Hardwood Sleepers,Rail Hardwood Ties, has good elasticity, light weight, easy fabrication, and other significant characteristics of insulation performance is good. Fasteners with wood blocking connection simple, laying and maintenance, transportation is convenient, wooden sleeper and have bigger friction coefficient between gravel ballast. Wooden sleeper toughening corrosion, can absorb more than other sleeper train weight and less prone to fracture. But its drawback is that use fixed number of year is shorter, consumption of large amount of wood. Wooden sleeper easy to corrupt, the reason from insect pests, the influence of the environment and climate, and the spike on the wood blocking hole by using long relaxation, wooden sleeper most commonly so only decades of life. To effectively extend the service life, sleepers generally must be used after filling the anti-corrosion. The sleepers, now use are embalmed, to prevent pests and to extend the use fixed number of year.
