Cable guide car
This system is developed from the foreign advanced technology & interrelated product. It suits the testof PD detect，withstand test and PD fault locate of the XLPE cables under 50OkV. The relevantrecommendations; GB/T11017-2002、GB/T12706-2008、and lEC60502-2005.
The whole system has the advantage of the compact structure，multi-function, easy operate andsafety. lt can supersede the analogously equipment of foreign production. It is composed of high voltagereactor, double shield isolation transformer, regulator, high voltage capacitive divider, high voltage injectioncapacitor, PD detector, PD fault locator and shielded room. The whole system more than three hundredhave been using in the electric wire & cable manufactures.
1、(Figure Drawing of the system )
2、 Main feature )
●PD level: ≤2Pc
●Quality facror: :Q≥40
●Accuracy of fault locating: ≤±2.5M ( ± 1% )
●Accuracy of voltage measurement: ≤ ±3%
●The system has the function of timer, ARC detector,interlock, over current protection, zero start andoutput tap setting control.Tuning range can work on the PD test, withstand test and fault locate of powercable of max.Cross-section 400mm2, longest length 2000m for rated voltage under 110kV.
3、（Main feature of shield room and control room )
●Resistance of ground is less than 1Q or less than resistance of ground power distribution.(These shallbe done by user according to our drawing)
●Resistance of insulating layer ≥ 100OMQ
Attenuation of shield room: 10kHz-100 kHz:60dB-80dB,
Dimensions of the shield room suits the user requirement. The whole structure of the building is madeof steel frames. The wall is covered with steel plate. Sandwich-structure color steel plates filled with formare used to decorate the outside wall The control room is composed of sandwich-structure color steelplates, the window and door is made of aluminum aiioy. The floor covered with internal decoration floorplates.
