 Description of technical parameters of current transformer

1, Main purpose and scope of use Cty series and ctyk series current transformers produced by our company. It is mainly applicable to the measurement, monitoring and relay protection of current and electric energy in AC circuits of 0.66kv and below.
This series of products are produced and tested according to the national standard gb1208, and the accuracy grade is better than the requirements of the national standard; At the same time, in order to meet the needs of modern microcomputer protection and other equipment for small current, the secondary output of this series can not only comply with 1a and 5A specified in the national standard, but also achieve Ma level output or mv level output. Compared with the former, the accuracy is greatly improved, and the accuracy is better than 0.1 specified in the national standard.
*  the product shell adopts imported flame retardant ABS, with flame retardant grade of 94-V0, high temperature resistance and good flame retardant performance.
*  epoxy resin is used for pouring, which is waterproof, moisture-proof, shockproof, high temperature proof and better stability. Combined with the optimization of magnetic materials and windings in product design, the working temperature of this series of products can reach more than 85 ºC, providing the most reliable guarantee for your equipment.
*  wiring mode: installation terminal type, stranded wire type (stranded wire ≤ 1m), screw injection type,
2, Service environmental conditions
*  ambient temperature - 30 ºC ~ 70 ºC, maximum temperature resistance 120 ºC
*  altitude ≤ 3000m
*  power frequency withstand voltage 3000V / 1min50hz
*  used in places without direct invasion of rain and thunder, serious pollution and violent vibration
3, Product model and technical parameters
*  measure CT primary current 5 ~ 6300A, secondary current 5A, 1a, 0.1A and 0.05A, protect CT primary current 200 ~ 6300A, secondary current 5A, 1a, 0.1A and 0.05A, residual current CT primary current 0 ~ 5a, secondary output voltage 1V or current 2mA, 20mA double winding CT primary current 5 ~ 6300A, secondary current 5A, 20mA, 1a and 20mA
*  rated working voltage ac0.66kv (equivalent ac0.69kv, GB156-2003)
*  rated frequency 50 ~ 60Hz
*  when used, the working current shall not exceed 1.1 times the rated current for a long time, it is allowed to be used for a short time at 1.2 times the rated value for no more than 1h, and the instantaneous (< 1s) working current shall not exceed 60 times the rated current.
4, When selecting low-voltage transformer, the general problems needing attention are as follows:
1). Determine the application environment of transformer: when selecting transformer, first clarify the primary current of transformer, and then estimate the size of primary conductor according to national standards. For example, the primary is a cable, and the diameter of the cable needs to be estimated according to the current; If it is a busbar, it is necessary to estimate the busbar width according to the current and corresponding data; If the cable diameter and busbar width have been defined, it can be directly used to select the perforation size of the transformer.
2). determine the service conditions of the transformer: after the through hole diameter of the transformer is determined, the transmission distance of the transformer must be considered. This determines the secondary load of the transformer, especially for the output 5a, the influence of transmission distance is particularly important and can not be ignored. Some customers feed back information during use and commissioning: the accuracy error of the transformer is relatively large, and then doubt the quality problem of the transformer. In fact, it is also the problem here. When ordering, the transmission distance is not considered, but the rated capacity of the selected transformer is too small, and the total load impedance of the secondary load and transmission line is greater than the rated capacity.
3). determine various electrical parameters of the transformer: determine the rated current of the transformer: select the rated current and the rated current ratio according to the measured current, and the general rated current is more than 2 / 3 of the load current. Determine the transformation ratio of the transformer: when the secondary current of the transformer is 5A and the measured current is relatively large (> 100a), the primary can be penetrated by a single turn; When the measured current is less than 100A, it is recommended to apply multi turn threading in the primary stage to improve the carrying capacity and accuracy. When the transformation ratio is very small, the accuracy of the transformer is difficult to be relatively high. If you want high-precision products, you need to increase the volume, thus increasing the cost.
4). Detailed treatment of transformer: the general standard transformer has a unified size. If the standard transformer cannot meet the application, it needs to be customized according to the installation space and site environment. Customization requires detailed parameters and strict installation dimensions.
