Working Environment
1. Location: Indoor or outdoor
2. Altitude: Below 2000m
3. Temperature: -45℃ ~ +45℃
4. Radial Ice Thickness: Less than 10mm
5. Earthquake Fortification: Class 8
6. Pollution Class: III, IV
Cautions
1. Make sure good ventilation for indoor use. The minimum face of capacitor face toward the sunlight for the longest time.
2. Mounted on the rack, spacing between layers must be more than 50mm, row spacing must be more than 150mm. The bottom of the capacitor should be no less than 200mm away from the ground for indoor use, no less than 300mm for outdoor use. The distance between the bottom and the roof shall not be less than 1000mm.
3. Soft connection for capacitors, must be The connection should be done by clamping two wrenches up and down. The tightening torque less than 52N·m.
4. Have the label outforward facing, to facilitate the inspection.
5. While mounting the capacitor on insulation rack, electric potential must be fixed.
6. Have the capacitor shell connect to the ground, Make sure the ground contact is good.
Notes
1. The capacitor should have the internal faulty protection, over-current, over-voltage, no-voltage protection;
2. When the voltage on the busbar exceeds the specified load, capacitor not allowed to connect;
3. When network disconnection, not allowed to reconnect within 10mins.
4. The capacitor discharge happens after network disconnection;
5. Before contacting the conductive part of the capacitor disconnected from the network, even if the capacitor has automatically discharged, the outlet end of the capacitor must be short-circuited and connected to the ground wire for separate discharge.
6. Frequently check whether the contact of all electrical connection points is good, and if there is an accident, it should be handled in time to avoid accidents.
Repair and replacement
1. Leaking
2. Capacitance loss more than 6%
3. Ground contact is short out
4. Insulating resistor to the ground less than 2000 megohm
5. The capacitor terminals cracks
6. The capacitor shell bulged
7. The operating time more than 10 years;
Frequently Asked Questions
What are the ambient working conditions required for these power capacitors?
They can be installed indoors or outdoors at an altitude below 2000m. The ambient operating temperature must stay within -45℃ to +45℃, with ice thickness less than 10mm, earthquake fortification class 8, and pollution class III or IV.
What is the recommended tightening torque for terminal connections?
Capacitors should use a soft connection. The connection must be tightened by clamping two wrenches up and down, keeping the tightening torque strictly below 52N·m to prevent damage.
How long must I wait to reconnect the capacitor after a network disconnection?
After a network disconnection, you must not reconnect the capacitor within 10 minutes to allow the capacitor to safely discharge.
What safety measures are required before contacting the conductive parts?
Even if the capacitor discharges automatically after network disconnection, you must short-circuit the outlet end of the capacitor and connect it to a ground wire for separate discharge before touching any conductive parts.
When should a capacitor be repaired or replaced?
A capacitor must be repaired or replaced if it leaks, has a capacitance loss exceeding 6%, experiences a shorted ground contact, shows insulating resistance to ground under 2000 megohms, has cracked terminals, a bulged shell, or has been in operation for more than 10 years.
