China 3-Phase HV Power Capacitor 100Kvar to 1000Kvar - Quality Suppliers & Reliable Factory Solutions

Specification Table

Working Environment

• Indoor or outdoor
• Altitude: below 2000m
• Environment Temperature: -45℃~+45℃
• Radial thickness of ice: less than 10mm
• Earthquake fortification class: 8
• Pollution class: III, IV

Cautions

• Make sure good ventilation for indoor use. The minimum face of capacitor face toward the sunlight for the longest time.
• 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.
• 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.
• Have the label outforward facing, to facilitate the inspection.
• While mounting the capacitor on insulation rack, electric potential must be fixed.
• Have the capacitor shell connect to the ground, Make sure the ground contact is good.

Notes

• The capacitor should have the internal faulty protection, over-current, over-voltage, no-voltage protection;
• When the voltage on the busbar exceeds the specified load, capacitor not allowed to connect;
• When network disconnection occurs, not allowed to reconnect within 10mins.
• The capacitor discharge happens after network disconnection;
• 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.
• 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

• Leaking
• Capacitance loss more than 6%
• Ground contact is short out
• Insulating resistor to the ground less than 2000 megohm
• The capacitor terminals cracks
• The capacitor shell bulged
• The operating time more than 10 years;
