HV test lab
It is mainly used in power transformers, high-voltage transformers, lightning arresters, high-voltage switches, high-voltage XLPE cables and other power products, and its main function is to prevent the interference of electromagnetic waves from space on the partial discharge measurement of the system, so as to ensure that the partial discharge test of power products is not interfered with by the outside.
• Rated voltage: 100kV ~ 2000kV (and above)
• Partial Discharge Performance: ≤ 2.0PC (after the completion of the shielded faraday cage, if the partial discharge of the equipment is less than 2PC, the noise level of the shielded hall system can also be less than 2.0PC)
• Dimensions: 120m (length)× 40m (width) ×39m (height)
• Attenuation method measurements: according to MIL-STD-285, IEEE299-1991;
• Insulation resistance: ≤10KΩ
• Magnetic field: 10kHz attenuation 60dB; Linear ramp up to 100kHz attenuation of 80dB
• Electric field: 80dB attenuation from 1kHz to 100kHz
• Ground resistance: < 1.0 Ω
Six-sided shield: 1 Set
Control room: 1 Set
Cable transport vehicle 10-100t: 1 car (transport weight 10-100t)
Shielded big door: 1 (height 2m-12m, width 1.5m-10m)
Shielded small door: 1 (height 2m, width 1.0m)
Ventilation channel windows: several
Lighting, power cabinets, grounding systems, and so on.
At present, we produce two types of high-voltage shielded hall structures
- spliced type
- welded type
Below table is example on power cable HV lab, we can customize dimension according to your requirement.
