LJK type zero sequence current transformerDetailed product description：

The LJK series square, open-ended zero sequence current transformer is a cable type, with an ABS engineering plastic shell and resin casting for full sealing. It has good insulation performance, beautiful appearance, high sensitivity, good linearity, reliable operation, and easy installation. Its performance is superior to general zero sequence current transformers. Widely applicable, it is not only suitable for electromagnetic relay protection, but also for electronic and microcomputer protection devices. Users can choose the appropriate zero sequence current transformer according to the operation mode of the system (neutral point grounded, neutral point ungrounded, high resistance grounded, low resistance grounded, arc suppression coil grounded).

Terms of Use
1. Environmental temperature: -10 ℃ to 60 ℃, with a daily average temperature not exceeding+40 ℃
2. Altitude ≤ 1000m (special order for high-altitude use)
3. Relative humidity ≤ 85%
4. The surrounding medium is free of conductive dust, conductive metals, corrosive gases, mold, etc. that may damage the insulation.
Product category and main data
1. Voltage 0.38-66KV
2. Grid frequency 50Hz
3. Same name end, once inserted from the front "L1" side of the transformer, and the second is "K1"
4. The model, data, and external dimensions are shown in the chart.

Install
1. The installation of the integral transformer should be carried out before laying the cable, and the cable should pass through the transformer during laying.
2. The installation of open-ended transformers can be carried out at any time, and the specific installation method is as follows:
(1) Remove the connecting pressure plates of transformers' K1 'and' K2 '.
(2) Loosen and remove the two hexagonal bolts on the top of the transformer, and the transformer will be divided into two parts.
(3) Insert the transformer onto the cable, clean the two contact surfaces, apply a thin layer of rust proof oil, align the two parts of the transformer, and tighten the hexagonal socket bolts to avoid affecting performance.
(4) Fix the connecting piece on "K1 '" and "K2'".
(5) The upper and lower parts of the open type transformer cannot be interchanged with other transformers.
