Assembling shunt capacitor

Introduction:

1. Small size and good appearance.

1. The shell is made by first-class steel.

1. According to different compensation structure, assembling shunt capacitor could be divided in to: Regular oil pillow type and full-sealed assembling shunt capacitor. 

1. The insulating oil of full-sealed assembling shunt capacitor is isolated from the air, to guarantee the insulating oil quality. The volume change of oil caused by the temperature could be compensated by the metal expander.

Environment　　　

1) Altitude：≤ 2000m

2) Ambient temperature：-25~55℃

3) Installation site：Indoor or outdoor

4) Capacitance tolerance between measured and rated is less than 0—+4%

5) The installation and operation site should be no conductive or explosive dust, no harmful gas and vapor, no tense mechanism shake.

Product characteristics

1) High quality raw materials: Adopt double-side roughened polypropylene film, ultrathin aluminum foil(4.5μm) and benzyl toluene oil for improving the product electric performance.

2) Foil edges auto-folding：Foil edges auto-folding at the two side terminals and edges in order to improve the distribution of electric field and level of partial discharge.

3) Internal fuse： Fuse with patented technology and elements of isolated structure can eliminate refusal-to-move, maloperation and group burst of fuses. Make the capacitors more secure and reliable.

4) Discharge resistor： Each series string has a discharge resistor, the high quality high-voltage glazed resistors can make capacitor’s residual voltage reducing from √2Un to less than 75V within 10 minutes after capacitors are power off.

5) Advanced core assembly line： The progress of core rolling, voltage withstand picking, internal fuse assembly, core compressing and core packing are all finished on the assembly line to guarantee the assembly quality.

6) Automatic TIG pulse welding: The welding of capacitor container joint, joint between container shell and container cap, joint between lifting hook and container are finished by robots, make the welding seam smooth, graceful, solid and no leakage.

7) Shot-blast treatment: Remove the dirt and oxide layer of the stainless steel, and roughen the surface to increase the adhesive strength of painting, and also inspect the container seam welding quality.

8) Painting robot: Import painting robot and super speed rotating electrostatic spray gun make the container painting even and smooth.

Application:

The assembling shunt capacitor installations are used for power correction, improving quality of network and reducing transmission line losses in the three-phase power system having frequency of 50 Hz and voltage of 6 kV, 10 kV and 35 kV respectively. The product has advantages of easy installing and maintenance, safe operation, smaller installing area requirement, etc., it is especially suitable for the situation of smaller installation space.
