Accuracy test

1、 Core parameters
Rated voltage: 35kV, suitable for medium voltage power systems, is a commonly used selection for high-voltage equipment procurement
Rated frequency: 50Hz/60Hz, compatible with mainstream global grid frequencies, can be directly adapted to projects in various regions
Insulation method: Oil paper insulation, using a combination of high-quality insulation oil and insulation paper, with stable insulation performance and strong voltage resistance
Installation form: Outdoor type, structural design suitable for outdoor environment, able to resist the influence of natural factors such as wind, rain, sand, etc

2、 Key technical indicators
One time current range: 5A~2000A, covering most measurement requirements for working conditions. Common specifications include 5/5, 10/5, 30/5, etc., supporting customization of special specifications according to procurement needs
Secondary current: standard 5A output, in line with international universal interface standards, can be directly matched with supporting equipment such as electric meters and relays
Thermal stability current: 1 second effective value (e.g. 5A current corresponds to 0.5kA, 2000A current corresponds to 1020kA), able to withstand short-term thermal shock under fault conditions without any risk of damage
Dynamic stable current: peak output (e.g. 5A current corresponds to 1.28kA, 2000A current corresponds to 2550kA), able to resist the electromagnetic force generated by short-circuit current and maintain structural integrity
Temperature rise limit: The maximum temperature rise of the winding is 55 ℃ (measured by resistance method/thermometer method), and the maximum temperature rise of the top oil layer is 50 ℃ (measured by thermometer method), effectively avoiding insulation aging due to overheating and extending product service life

3、 Precautions for use and procurement
Production and maintenance: The LB6-35 Current Transformer undergoes vacuum drying and oil immersion treatment before leaving the factory to thoroughly remove moisture and air, ensuring insulation reliability; Due to the non fully sealed structure, the oil quality needs to be checked regularly during use, and filtration or replacement may be necessary to ensure the continuous and stable operation of the equipment

Applicable scenarios:

LB6-35 Current Transformer is designed specifically for current monitoring and protection of high-voltage transmission lines, it can provide accurate current signals, support energy metering, relay protection, and system control work, and ensure the safe and stable operation of the power grid.
