Open type current transformer for energy-saving renovation

Description :

　　AKH-0.66K Open Type Current Transformer

　　Selection and installation methods

　　Select the corresponding specification product based on parameters such as primary current and busbar cross-section. A wire passes through the transformer window once. Open the flip cover, perform secondary wiring through the crimping piece, and reset the flip cover after the secondary wiring is led out. Measuring electrical energy can be directly achieved by sealing the small holes on the flip cover with lead seals to prevent electricity theft.

　　The working current shall not exceed 1.1 times the rated value for a long time, and it is allowed to be used for a short time at 1.2 times the rated value for no more than 1 hour;

　　According to the magnitude of the measured current, select the rated current ratio, generally choosing a rated current that is about 2/3 larger than the measured current;

　　The polarity of the product is represented by the primary wiring symbols P1 and P2, and the corresponding secondary wiring symbols S1 and S2; S1 represents the same named end of P1, and S2 represents the same named end of P2;

　　The measuring instrument is connected to terminals S1 and S2. At this time, the total load of the connected circuit should not exceed the rated load of the transformer. When the installation location of the instrument is far away from the current transformer or the circuit load is large, the secondary current specification of 1A should be preferred;

　　Pay attention to selecting transformers with matching window sizes based on the specifications and number of busbars.
