1. Descriptions and applications
KYN61-40.5 armored metal enclosed switch cabinet is the latest product developed by our company using the foreign technology brought in. It meets the requirements of GB3906, IEC298, IEC694, DL404 and other standards. It applies to all kinds of substations, power stations, industrial and mining enterprises, high-rise buildings, and it's particularly suitable for frequent operation occasion.
2. The features of the products
1)Programmed and formulized operation interfaces make operation easy for operator.
2)Promoting institutions with unique design make handcart realize automatic positioning in the process of pushing in&out, also enable the isolated contacts to contact more reliable.
3)The height and wedth of the tools handcart is adjustable and realize interlocking with the switchgear. It can put different kinds of handcarts on he ground and platform to maintain.
4)CT installation is changed cabinet back vertical installation to suspension setting, the space of cable chamber increases to 800m3, it's convenient to install and maintain the cables.
5)Handcart, earthing switch and cable chamber interlocks with each other. When handcart is working, the operation botton of earthing switch is locked that the earthing switch can't close; When the earthing switch is closed, the handcart can't move; And if the earthing switch is not closed, the door of the cable chamber can't be open.
6)Circuit breaker interlocks with cabinet door. Cabinet door isn't closed, the circuit breaker can't work, so that it can preserve human body from hurting by electric arc. When pull out the circuit breaker, the cabinet door will be shut automatically and locked forcibly to avoid error touch to high voltage parts.
7)Advanced electric-field distribution and design of insulation structure make the insulation of product more reliable.
