Partial Discharge System for XLPE cable under 500KV --- Wire Cable Testing Machine
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.
- Main feature
1.1 PD level: ≤ 2 Pc
1.2 Quality factor: ≥ 40
1.3 Accuracy of fault locating: ≤± 2.5M (± 1%)
1.4 Accuracy of voltage measurement: ≤ ±3%
1.5 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.
2. Main feature of shield room and control room
2.1 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)
2.2 Resistance of insulating layer ≥ 1000M Ω
2.3 Attenuation of shield room: 10kHz-100kHz:60dB-80dB
10kHz-100MHz:70dB-100dB
2.4 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.
