JYFK series intelligent compound switch(capacitive switch)

Functions＆Features

○Control function

1.Auto searching to find the best opportunity to switch, quick response

2.When the switch is taking action, closing at voltage through zero, opening at current through zero

○Protection function

1.when phase failure, switch will automatically self-lock and close

2.At normal operation, f phase failure occur, the response time not more than 0.2s

3.When system is out of power supply, switch will automatically trip, response time not more than 0.2s

○Displaying function

The switch has the indication of ON, OFF, and phase failure

Working condition

○Ambient conditions

1.Temperature:-40℃-70℃

2.Relative humidity:＜50%at+40℃

＜90%at 20℃

3Altitude not more than 2000m

4.Vibration:no severe vibration and impact allowed

○Operating conditions

1.Input control value:

Voltage signal: High potential(3.8-24V) for control switching on,Low pote -ntial(0V-0.7v)for control tripping, DC input resistance≥2KΩ,

2.Power consumption: public compensating switch not more than 3W,separately compensating switch not more than 5W

3.Input performance:at normal use,insulating resistance not less than 10mΩ,insulating level between phase to enclosure or to earth:AC2500V 50Hz,1min

Characteristics

○The contacting resistance of the switch ≤0.002Ω，the temperature rise at rated current ≤10℃

○The system voltage is within 20%-+15%rated voltage,itcan work normally

○During switching the surge current is not more than 1.5times of rated

Current of the capacitor

○Switch response time≤30ms，the space between two operations:public compensating switch:45A(380v)≥30s；others≥6s

○The residual voltage on the terminals of the capacitor is not more than the one which it occur when at 100%rated voltage the current pass through zero

○When closeing at dynamic voltage through zero zero-point voltage shall not more than 1.5%rated voltage(electric phase angle 1°)

○Operation life:3*105operations

Outline size:191mm*116mm*82mm
