RPC / RCM / RCL capacitor racks (withdrawable modules) for 0.4 kV reactive power compensation switchboards
Country: Italy · Model: RPC / RCM / RCL
The withdrawable capacitor racks RPC, RCM and RCL arrive on site as a ready 0.4 kV compensation step, in the RPC series from 25 to 100 kvar at 400 V. Three-phase sets of single-phase capacitors, a contactor and fuses are already mounted on a galvanized steel frame, and in anti-resonance versions a reactor as well, so a panel builder assembles from them a bank of the required power in their own cabinet.

Description
The RPC racks fit 19-inch cabinets of data centres and energy centres, and their RPC-B15 and RPC-B50 versions have a power of 25, 50, 75 or 100 kvar, as well as 37.5 kvar, and contactors with pre-insertion resistors. The RCM racks go into G6E and G8E cabinets, without reactors (B15, B35, B50) or in the anti-resonance versions AAR/100, AAR/600, AAR/6, AAR/138, AAR/D20. All RCL racks for G9E cabinets have blocking reactors AAR/138 or AAR/D20. The self-healing MKP capacitors with a pressure protection device and a discharge resistor are impregnated with vegetable oil free of PCB and connected in delta, and they withstand 1.1 Un overvoltage and 1.3 In current, with a capacitance tolerance of −5/+10 %. The reactors of 189 Hz (p = 7 %) or 138 Hz (p = 14 %) have a temperature sensor that switches the step off on overheating. The power circuits are protected by NH-00 gG fuses of 100 kA and switched by AC6-b contactors, and the auxiliary circuits are supplied from 230 V AC.
How to choose
The version is chosen by the current THD in the network. Without a reactor the B15 works up to 15 %, the B35 up to 25 %, the B50 up to 35 %, and the anti-resonance AAR versions withstand up to 100 %. As the permissible harmonic level grows, so does the capacitor voltage, from 415/450 V in the B15 and 450/500 V in the B35 to 500/550 V in the B50, AAR/100 and AAR/600, and 550/600 V in the AAR/6, AAR/138 and AAR/D20 versions. The steps are controlled by a BMR 4, BMR 6 or HPR controller, and for targeted sinking of the 5th harmonic there is the passive FAM05 filter for 245 Hz.

FAQ
Does a cabinet with RCM capacitor racks need ventilation?
Yes, the rack is IP00 and has no fan of its own, so ventilation and the enclosure are provided by the panel builder.
What losses does the reactor of an anti-resonance rack have?
A 189 Hz reactor has losses of 6 W/kvar and a 138 Hz reactor 6.5 W/kvar, and they are included in the thermal calculation of the cabinet.
What are the dimensions of the RPC module for a 19-inch cabinet?
The dimensions given for the RPC module are 440 × 340 × 490 × 270 mm.
Which standards and directives do the RCM and RCL racks comply with?
The racks comply with IEC/EN 60831-1/2, EN 61921 and directives 2014/35/EC and 2014/30/EC, and 100 % of them undergo inspection and insulation tests.
