Wire Cable Testing Machine Partial Discharge System for XLPE cable
under 500KV
This system is developed from the foreign advanced technology &
interrelated product. It suits the test of PD detect, withstand
test and PD fault locate of the XLPE cables under 500KV. The
relevant recommendations: GB/T11017-2002, GB/T12706-2008 and
IEC60502-2005
The whole system has the advantage of the compact structure,
multi-function, easy operate and safety. It can supersede the
analogously equipment of foreign production. It is composed of high
voltage reactor, double shield isolation transformer,regulator,
high voltage capactive divider, high voltage injection capacitor,
PD detector, PD fault locator and shielded room. The whole system
more than three hundred have been using in the electric wire &
cable manufactures.
- Figure Drawing of the system
- Main feature
PD level: ≤ 2 Pc
Quality factor: ≥ 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 and output tap setting control.
Tuning range can work on the PD test, withstand test and fault
locate of power cable of max. Cross section 400mm2, longest length
2000m for rated voltage under 110KV.
- Main feature of shield room and control room
Resistance of ground is less than 1 Ω or less than resistance of
ground power distribution. (These shall be done by user according
to our drawing)
Resistance of insulating layer ≥ 1000M Ω
Attenuation of shield room: 10kHz-100kHz:60dB-80dB
10kHz-100MHz:70dB-100dB
Dimensions of the shield room suits the user requirement.The whole
structure of the building is made of steel frames. The wall is
covered with steel plate. Sanwich-structure color steel plates
filled with form are used to decorate the outside wall. The control
room is composed sanwich-structure color steel plates, the window
and door is made of aluminum alloy. The floor covered with internal
decoration floor plates.
