Product description
Destination:
Mobile grounding and short-circuiting devices are used according to labor protection norms in the internal and external electrical installations of electrofilters (de-energized).
They serve to delimit the work or protection area.
Constructive and functional characteristics:
Mobile earthing devices consist of:
• electrical insulating rod L = 1500 (2000) mm
• application lamella on the phase - made of brass with a section of 50 mm²
• bronze earthing clip
• flexible grounding conductor s = 35 mm² length 3000 mm.
The short circuit consists of:
• 2 bronze earthing clamps
• flexible grounding conductor s = 35 mm2 length 3000 mm
Before de-energizing the bars to be connected to the ground, there is a continuous voltage (made from the alternating voltage) with the following parameters:
• The rectified voltage at the peak 80 / 111 kV
• Negative polarity
• Arithmetic value 55 /65 kV
• Mechanical resistance 1500 N
• Short circuit current 5 kA for 0.5 seconds
Symbology:
For mobile grounding device:
• Msp P111 -1 x 40 + 35/3 -0
• Msp P – grounding device pole type
• 111 – the peak-corrected value
• 1 x 40 – 1 application blade per phase
• 35/3 – flexible conductor with a section of 35 mm, 3m length
• 0 – assembly is done on round conductor
Mod de comandare:
Mobile earthing device 111 kV
For short circuit:
Short circuit 100 E – 11A
