    The 2021 PTS 7th China International Power Transformer Market and Technology Development Summit Forum

    2021-07-07

    Background of The Forum

    01.Present Situation

    In power system, power transformer is the basic equipment of power transmission and distribution, and it is also an important primary equipment. There are about 17 million transformers operating on the grid in our country, with a total capacity of 11 billion kVA. Transformer loss accounts for about 40% of the power loss of transmission and distribution. According to the calculation, the annual power loss is about 250 billion kWh, which has great potential for energy saving.

    02.Policy Implementation

    On January 15, 2021, the general office of the Ministry of industry and information technology, the general office of the State Administration of market supervision, and the General Department of the National Energy Administration officially released the “Transformer Energy Efficiency Improvement Plan (2021-2023)”. Compared with the original standard, the loss index of various types of transformers in the new standard has decreased by about 10-45%, which is superior to the requirements of the relevant standards of the European Union and the United States.

    03. Exploration

    The formulation and implementation of a new round of transformer energy efficiency improvement plan can not only promote the optimization and upgrading of China’s transformer industry chain, accelerate the improvement of transformer energy efficiency, but also reduce the level of transmission and distribution losses, further promote the green, low-carbon and high-quality development of the grid, increase the supply of high-efficiency transformer market, and expand  green new kinetic energy.

    Since its implementation on June 1, the entire industry chain of power transformers has paid great attention to this event. As industrial  information integration platforms focusing on global power transformers, 「WangCai New Media] and「Power Transformer Focus 」 also used their own advantages to plan “The 7th China International Power Transformer Market and Technology Development Summit Forum”

    This forum will provide an in-depth interpretation of market policies, raw materials, and energy efficiency improvement technologies, combined with the future direction of the industry. And topics about the digital upgrade of power transformation technology, the development of advanced transformer technologies, and the green manufacturing of power equipment will also be discussed.

    LVQB-220 SF6 Gas Insulation Standalone Current Transformer was Widely Used by China Southern Power Grid

    2021-04-03

    LVQB-220 standalone current transformer insulation in SF6 gas was widely usde by  State Grid Corporation of China.

    The standalone current transformer is for the current measuring and protection for the power systems.

    Rated voltage: 40.5kV~550 kV

    Rated primary current: 50~8000A

    Rated secondary current: 1A, 2A, 5A

    Rated frequency: 50Hz or 60Hz

    Maximum output: 200VA(GB, IEC AS standards), or B-1.8, C800 (IEEE standard)

    The accuracy classes: 0.2S, 0.2, 0.5S, 0.5, 5P, 10P, PX, PR, TPY, TPZ (GB, IEC AS standards),

    or 0.15, 0.3, C (IEEE standard)

    The bushing is made by silicon rubber or porcelain.

    The enclosure is made by aluminum alloy casted, there is SF6 density monitor to monitor the

    gas pressure, and with a pressure relief device, the produce is very safe. The insulation material

    is SF6 gas, the leakage not exceed 0.1%/year. The partial discharge less than 5 PC.

    The product service life is very long , more than 30 years even get to 40 years and do not need

    any special maintenance. Our technology has reached the international leading level.


    Current transformer works

    2020-11-20

    The Current Transformer 

    The Current Transformer ( C.T. ), is a type of “instrument transformer”

    It designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary.

    Current transformers reduce high voltage currents to a much lower value.

    It provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a standard ammeter.

    The principal of operation of a basic current transformer is slightly different from that of an ordinary voltage transformer.
