KYN-40.5 Series
This series of products are suitable for indoor single busbar and single busbar section in power system, of three-phase AC 50Hz, 40.5kV rated voltage, and main busbar rated current up to 2500A. For the moment, the technical parameters are in the leading level in domestic.
Main Features

The products are metal-clad enclosed structure, which consist of enclosure and handcart. The enclosure is designed as the assembly style, adopting aluminum-zinc steel plate,using double folding process by CNC equipment. As a result, the product with high mechanical strength and good appearance has strong capacity of anti-corrosion and anti-oxidation. According to different applications, the handcart can be classified as circuit breaker handcart, voltage transformer handcart, metering handcart and isolation handcart, which greatly meet user’s requirements for various schemes. Handcart applies Screw propulsion mechanism, and with the help of self-locking nature of the screw, it can prevent accidents caused by handcart traverse due to the role of electric power. Function compartment is provided with a separate pressure relief passage, the device will automatically open to release the internal pressure when an arc fault occurs, in order to ensure the safetey of personnel and equipment. The product is designed as composite insulation, and by optimizing the electrode geometry, the device is made to be compact structure and reliable insulation to meet the full conditions required. The bushing and the contact box adopts external shielding structure with mean internal pressure, effectively suppresses the thermal breakdown and the electrochemical breakdown of solid insulating materials under AC electric field, therefore to improve the insulation life as well as prevent it from aging. The product contains the earthing switch operating mechanism interlock device with our independent intellectual property rights, which strengthens the reliability and safety of the products, and meets the “Five prevention” requirements.

Application Areas

The product has been widely used in petrochemical, metallurgy, cement, textile, power plants, enterprises and institutions, for the distribution incoming and distribution of power system secondary substation, used as control protection and monitoring.

Other Features

With the help of computer technology, network communication technology, the product can be used for measurement (voltage, current, active power, reactive power), metering (active energy, reactive energy), protection (quick break, overcurrent, ground, reclosing, over-voltage, under voltage, unbalanced voltage, unbalanced current), control (clsoing and opening of circuit breakers and electrical equipment), recording (phase current and voltage waveform when breakdown) ,displayi (electricity, running status), communications, complete equipment status monitoring and fault diagnosis (including online status monitoring, “four remotes" functions, fault recording, analysis and communication).
