New current transformer analysis

The split core current transformer is mainly used for electrical measurement and electrical maintenance. It has the characteristics of high flexibility, good linearity, reliable operation, and convenient installation, especially its open-close structure can be completed without tools. Without changing the cable, the device can be used more and more widely. We can choose the corresponding split core current transformer ratio according to the operation requirements of the system.   Split core current transformer   1. Select the corresponding specification product according to the parameters such as primary current and busbar section. A wire passes through the window of the transformer.   2. When the instrument position of this device is far away from the current transformer or the loop load is large, the specification of 1A secondary current should be given priority;   3. Pay attention to the number and specifications of the busbar, and then we can determine to choose an split core current transformer that matches the window size.   4. We can choose the ratio of the rated current ratio according to the size of the measured current. We should choose a rated current that is two-thirds larger than the measured current;   But there are things that need to be paid attention to, for example, when we open the flap, stop the secondary wiring through the crimping piece, and reset the flap after the secondary wiring is led out. Electric energy metering can be directly applied to the small hole of the flip cover to increase the seal and prevent electricity theft.   The working current of the split current transformer does not exceed 1.1 times the rated value for a long time, but it can be used for a short time at 1.2 times the rated value, but pay attention to the time, the time cannot be too long, and the time cannot exceed 1 hour;   Split current transformers are suitable for general measurement and maintenance of highly maneuverable, limited space or non-continuous power systems.   Hemei Electronics, with products covering more than 30 provinces, cities and districts in China and exported to more than 20 regions, mainly produces magnetic materials/current transformers/power supply CT/transformer cores/electromagnetic shielding shells/high-frequency current transformers and other business segments.
