Review of the product
KYN28A-12 Armored removable metal distribution device of alternating current is suitable for an internal three-phase 50 Hz with a nominal voltage of 12 kV of a power supply system, mainly used at power plants, substations, industrial and mining enterprises, electricity distribution centers, as a reception and distribution of electric energy and management, protection and monitoring of the chain. KYN28A-12 Distribution device has various functions of protection against improper operation, including preventing the movement of the trolley with the load, preventing the ground switch from closing the circuit breaker in the closed position, preventing the ground switch from closing on behalf of the pad to prevent an accidental entrance into the charged compartment and other functions. The KYN28A-12 distribution device is equipped with various functions to prevent improper operation, including preventing the movement of the cart with the load, prevention of the circuit breaker in the closed position of the ground switch, the prevention of the ground switch on the block, the prevention of an erroneous entrance to the electrified compartment.
The KYN28A-12 circle is equipped with high-voltage vacuum variable current switches with excellent characteristics, such as 3AS-12, VD4, HVX12, etc. The secondary circuit of the circle is equipped with reliable control and protection elements; The tire has a heat -shrinkable casing to cover insulating products, optimizes the shape of the electrodes, and the cabinet has a compact structure. The Kyn28A-12 is technologically advanced, has stable characteristics, reasonable structure and ease of use, safe and reliable equipment for the distribution of electricity.
The value of the model
terms of Use
1. Environmental temperature: upper limit +40 ° C, lower limit -25 ° C.
2. Relative humidity: an average daily no more than 95%; The average monthly is not more than 90%.
3. Height above sea level: no more than 1000 m.
4. The surrounding air should not be noticeably contaminated with dust, smoke, corrosion and combustible gases, pairs or saline fog.
5. Vibration or the movement of the soil outside the distribution device and control equipment is insignificant.
If operating conditions go beyond the above range, the user must consult with us to determine the permissible range and technical measures.
Advantages of performance
1. The good electrical characteristics: the nominal current is usually 630A and lower, which can satisfy the demand for the distribution of electricity and control in various scenarios. Due to the high strength of insulation and explosive ability, it can ensure stable operation of the energy system.
2. Function of the blocking: it is equipped with a perfect function of the “five -profile blocking”, i.e. Prevention of opening and closing the switch with a load, preventing the wrong entry into the charged interval, preventing improper opening and closing the main switch, preventing the closure of grounding equipment with electricity, preventing the ground switch from the supply of electricity when closing, which effectively prevents the safety risk caused by improper operation.
3. Bending and convenient operation: it can be manually controlled or electrically, which is convenient for users to choose in accordance with the actual needs.
