AKH-0.66K series open current transformer renovation project

Description :

　　Overview:

　　AKH-0.66K seriesLow voltage switchable current transformerEasy to install, no need to dismantle the busbar once, can also be operated with electricity, does not affect the normal use of electricity by customers, and can be used in conjunction with relay protection, measurement, and metering devices. Mainly used in power distribution system renovation projects, it is easy to install, does not require dismantling the busbar once, and can also be operated with electricity, without affecting the normal use of electricity by customers. It saves manpower, material resources, and financial resources for user renovation projects and improves efficiency. This series of current transformers can be used in conjunction with relay protection, measurement, and metering devices.

　　Selection instructions: 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 should 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. Based on the size of the measured current, the rated current ratio should be selected, generally about 2/3 larger than the measured current; The polarity of the product is represented as: primary wiring symbols P1 and P2, 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 the S1 and S2 terminals, and 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.
