6KV Biasing magnetic Petersen coil

6KV Biasing magnetic Petersen coil

6KV Biasing magnetic Petersen coil

1.Steplessly and continuously adjustable
2.Dynamic compensation,no damping resistor is required

1.Purpose:

This product is used in 6KV~66KV systems whose neutral point is ungrounded to limit the arcing currents during ground faults.

when single-phase grounding takes place, it is capable of adjusting the reactance in a very short time to make residue reactive component of fundamental wave become zero.

 

 

2.Features:

2.1           High precision of regulation

2.2                 High reliability and long service life

2.3                 Rapid response

2.4                Online real-time scanning and automatic tracking compensation

2.5           Dynamic compensation, no damping resistor is required

2.6           Dynamic compensation, no damping resistor is required

3.Principle:

6KV Biasing magnetic Petersen coil

 

4.Structure:

4.1             Control cabinet

4.2             Biasing magnetic arc-suppression coil

4.3             Grounding transformer( The grounding transformer is used to provide an artificial neutral that can carry load in the 6kV and 10kV, 35 kV systems without of neutral points for use of body of arc suppression coil. )

THT-LJK120J Zero-sequence Current Transformer

THT-LJK120J Zero-sequence Current Transformer

THT-LJK120J Zero-sequence Current Transformer

1.high precision
2.good linearity
3.safe operation
4.artsy exterior
5.convenience installment,fixing space saving

1.Service conditions:

1.1 Highest temperature: +80°C;

1.2 Daily average temperature: +60°C;

1.3 Lowest temperature: -20°C.

1.4 Height above sea level: 1000m (When specially orders for plateau using)

1.5 Relative humidity: <85%

 

2. Main data about products

2.1 AC voltage: 0.4kV (electric cable)

2.2 Electric network frequency: 50Hz

2.3 Homonymy end: The primary side is “L1”. The secondary side is “ K1”  

2.4 The model, the data and the outlook sizes see the graph.

 

3. Installment

3.1 The unit transformer has no limit of the cable laid or not, the concrete method as follows:

3.1.1 Dismantles the joint sheeting of "K1/" " K2";

3.1.2 Loosening and dismantling the two inner hexagon bolts, then the transformer can be divided into two parts;

3.1.3 The transformer is wrapped on the electric cable, polishes two contact faces, lightly spreads anti-rust oil, twists in the hexagon bolt after corresponding the two parts, the two parts must to be together in order to avoid effecting performance;

3.1.4 Unite the joint sheeting to fix on "K1/" " K2" ;

3.1.5 The two parts of the unit transformer cannot be exchanged with others of them.

  THT-LJK120J Zero-sequence Current Transformer

Note:Φ8.5 X 4 bores are pass bores ,B,C is the size within the four bores; the transformer can be installed horizontally.We suggest using the M6 bolts to install the transformer.
