Zhejiang Dahu Electric Co., LTD is a professional manufacturer of high and low voltage transformers.
Hello, here are some detailed information about LZZBJ9-35 type rear-mounted extended output current transformer:
Product Overview:
LZZBJ9-35 type current transformer is suitable for rated frequency of 50Hz, rated voltage of 35kV power system, power supply gas measurement and electrical protection with
.
Normal use conditions:
Ambient temperature: Maximum 65 ºC, daily average does not exceed 40 ºC, minimum -45 ºC.
Altitude not exceeding 1000m.
Installation place: inside 35kV vacuum circuit breaker.
Atmospheric conditions: the atmosphere is free from filth and aggressive and explosive media that seriously affect the insulation performance of the transformer.
.
Structure Introduction:
This type of transformer is indoor epoxy resin casting fully enclosed structure, its core is made of microcrystalline alloy or high-quality magnetically conductive silicon steel sheet wound into a ring, the secondary conductor is evenly wound on it. The primary conductor is wrapped with reinforced insulation to avoid turn-to-turn short circuits between the conductors. Primary and secondary coils are cast in epoxy resin, with good insulation and moisture resistance, is an ideal alternative to oil-immersed transformers.
It is an ideal alternative to oil-immersed transformers.
Technical Parameters:
The ratings of the transformers are shown in Table 1, including the rated outputs, rated short-time thermal currents (RMS) and rated dynamic stabilizing currents (peak) at different combinations of accuracy levels
.
Insulation level: 40.5/95/185kV.
.The product implementation standard is GB20840.2-2014 current transformer
.Installation use and maintenance:
The transformer arrives at the use of units need to do the following checks: packing list, product certification, instruction manual and factory certificate of conformity should be attached to the packing box. Product specifications should meet the requirements. The product structure has no defects or damage caused by transportation or other reasons.
The product structure has no defects or damages caused by transportation or other reasons.
The grounding bolt should be properly grounded before the transformer is used. During operation, the secondary winding must be reliably connected to the load, and the secondary winding not in use must be shorted to the secondary outlet terminal.
The secondary winding must be connected to the load reliably during operation.
Outline and mounting dimensions:
Specific information on the shape and installation dimensions can be referred to the product specification or the information provided by the manufacturer.
LZZBJ9-80
This LZZBJ9-35 type current transformer is widely used in power systems for its miniaturization, stability and reliability, especially in 35kV miniaturized switchgear.
