China Power Transformer type test standard
We have a perfect quality management system. Each china power transformer will be tested in strict accordance with relevant standards before delivery and make sure our chinese power substation transformers which will meet clients requirements.
Our chinese power Transformers are common and important equipment in the power system, and their safety and reliability play a vital role in the operation of the power grid. In order to ensure the performance and quality of transformers, it is necessary to carry out a variety of type tests to verify that it meets the relevant standards and specifications. This paper will introduce the standard contents and requirements of transformer type test.
First of all, the type test of transformer includes, but is not limited to, the following aspects, temperature rise test, short time test, overload test, partial discharge test, electrical strength test, insulation resistance test and so on. These test items are designed to verify the performance and reliability of the transformer under normal and abnormal operating conditions.
When conducting type tests, they need to be operated in strict accordance with the relevant standards and specifications. For example, the temperature rise test needs to be conducted in accordance with the requirements of national standard GB1094.1-2013 “Power Transformer Part 1, General Technical Requirements” to ensure that the temperature rise of the transformer under rated load conditions meets the standard requirements. And the short-time test needs to be carried out in accordance with GB1094.2-2013 Power Transformers Part 2, Tests, to verify the performance of the transformer under overload conditions for a short period of time.
In addition to national standards, there are also some common international standards, such as the IEC standard. When conducting the type test, standards such as IEC60076-1 “Power transformers - Part 1: General” can be referred to ensure the comprehensiveness and accuracy of the test.
During the test, data collection and recording are required in strict accordance with the standard requirements. Various parameters of the transformer, such as temperature, current and voltage, need to be monitored during the test and the data recorded. These data are essential for assessing the performance and reliability of the china oil power transformer.
In addition to data collection during the test, the test results need to be analyzed and evaluated after the test. By analyzing the test data, the performance of the transformer under different operating conditions can be derived, so as to assess whether it meets the standard requirements.
In general,our china power transformer type test is an important means to ensure transformer performance and reliability. Through the test in strict accordance with the standard requirements, can effectively verify the quality and performance of the chinese power substation transformer, for its safe operation in the power system to provide protection. I hope that this article can help the standard content and requirements of transformer type test, and provide reference for the safe and reliable operation of the transformer.
TEST LABORATORY
Type Tests
-
Temperature Rise Test IEC60076
In this test, the compliance of oil and winding temperatures with both standard and technical specifications is verified.
-
Determination of Sound Levels IEC60076
It is the verification that the sound (noise) level created by the transformer and its related equipment under operating conditions meets the customer requests and/or the demands in the standards.
-
Light Impulse Test (LI) IEC60076
Impulse tests are applied to transformers in order to verify their resistance against both atmospheric lightning discharges and transient overvoltages during switching.
It is to determine the life of the transformers by vacuuming and filling the boilers depending on the temperature and pressure changes in the operating conditions of the transformers.
