Product Details

Electrical Cubicle KYN61-40.5 Draw-out HV Metal Enclosed Switchgear


Introduction:

It is an indoor switchgear, assembly operating under the conditions of three phase 50/60Hz and rated 40.5KV AC voltage.

It complies with GB3906-2006, IEC62271-200 and other relative standards.

 

Features:

●The switchgear and partition boards adopting Al-Zn alloy coated steel plates and frame adopting multiple bending technology make high overall intensity and good earth continuity.

●The switchgear is combined type and the handcart of breaker is floor structure type.

●The new composite insulating vacuum circuit breaker has the characteristics of interchangeability and simple replacement.

●The handcart adopts screw propulsion mechanism, which moves the handcart easily and prevent misoperation to damage the propulsion mechanism.

●All the operations could be done when the cabinet door is closed.

●The interlocking between the main switch, the handcart and the switch cabinet adopts the mandatory mechanism of mechanical locking, meeting the functions of five-preventions.

●The cable room is spacious and can be connected to a number of cables.

●The protection level is IP4X, which effectively prevents the equipment from being invaded by sundries and insect pests.

●The switchgear runs safely and reliably through the harsh condensation, filth and internal arc tolerance test.

 

Service environment:

(1) Normal operating conditions:

- Ambient temperature: -10 ° C ~ 40 ° C

- Daily average RH does not exceed 95%; monthly average RH does not exceed 90%

- The daily average value of steam pressure does not exceed 2.2k Pa and does not exceed 1.8kPa

- the altitude does not exceed 1000 meters;

- the surrounding air is not responsible for any pollution, smoke, password or flammable air, steam or salty fog;

- the external vibration of the switching device and the control device or the terrestrial dither is negligible;

- The secondary electromagnetic interference voltage caused in the system is not more than 1.6kV.

(2) Special operating conditions

- According to IEC60694, GB / T11022, manufacturers and users can agree on special service conditions to deviate from normal service conditions

- In order to prevent condensation, the switchgear needs the heater to be put into use

- When the switch ears are ready and service conditions. The heat problem of the switch ear can be

Solved by ventilation facilities.

 

Applications:

It is mainly used for power transmission & distribution for generators, transformer substations and the industry and mine enterprises. It can also be used to control, protect and monitor electric circuits, and useful to frequent operating conditions.
