17.5KV 1250A Armoured type high voltage panel cabinet

Short Description:

KYN28-12 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a new type of product designed and developed by our company on the basis of absorbing domestic advanced manufacturing technology, which can replace various old metal-enclosed switchgear, such as KYN1-12, JYN2-12 and other products. Its products have the following obvious advantages: the shell of the product is completely assembled by bolts, which has high mechanical strength, which effectively ensures the neatness and beauty of the product, and the cabinet door is sprayed with plastic, which has strong impact resistance and corrosion resistance. The enclosure has an IP4X rating. The switch of this product can be equipped with VD4 vacuum circuit breaker produced by ABB, C3 series fixed load switch, and can also be equipped with a variety of domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace similar foreign products. No matter what kind of circuit breaker is selected, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation is greater than 60mm. Its circuit breakers have the unique advantages of long life, less maintenance and small size.

KYN28A metal-cased closed drawer switch device is suitable for 3.6~15kV three-phase AC power network of 50Hz. The equipment can be used for power distribution and control, monitoring and protection of the power circuit. It can be applied to the singular bus, and double bus system.
The following notable merits are included:
Shield is composed of aluminum, zinc and bolt, enjoying high mechanical strength. The painted doors of cabinet make the device nice-looking and elegant. Shield protection level is IP4X.
China-made VS1 series vacuum breaker, as well as VD4 vacuum breaker (made by ABB) is adopted for the main switch.
Any breaker adopted boasts merits including: long lifetime, less maintenance and small size etc.
Perfect and reliable functions prevent wrong operation.

STRUCTURAL CHARACTERISTICS
It consists of two main parts: cabinet and middle type withdrawable part (handcart).Cabinet is divided into four separate chambers. I’ts shell’s protection level is lP4X and when the doors of the chambers and breaker are opened itsIP2X. This switchgear can be installed, adjusted and maintained from the front, therefore it can be installed back to back, against the wall and in dual arrangement
1.Shell and others
The main cabinet of switchgear is made of imported aluminized zinc thin sheet steel and the use of multi-fold process, endowing the cabinet with anti-oxidation and strong corrosion resistance
2.Handcart
The Handcart and cabinet insulation coordination and the mechanical interlocking is safe According to different application purposes, handcart can be divided into breaker
Handcart voltage transformer handcart, metering handcart, isolation handcart and so on. According to different modulus, various handcarts change in the building block way. Handcarts with the same specifications can exchange completely freely. lf we want to withdraw handcart from cabinet, a specifications trolley is enough. Besides, due to the mid-set design, the handcart has a small volume which enables the checking and maintenance work extremely convenient
3.Chamber
The main electrical components of switchgear have their own independent chambers, SP breake handcart chamber, bus chamber, cable chamber and relay instrument chamber. Between the chambers have reached the degree of lP2X , Except for relay chamber, the other three chambers their own pressure relief channels
4.Anti-misoperation interlocking device
Switchgear contains safe and reliable interlocking device, completely measuring up to the requirements of “five preventions”
5.Essure relief device
Essure relief device is installed above the breaker handcart chamber , bus chamber and cable chamber. When fault arc inside the breaker or bus occurs, then the pressure relief metal plate installed on the top will open automatically, releasing and discharging gas to make sure the safety of operators and switch cabinets.
