KYN28A-12(Z)indoor armored removable switch cabinet

Overview

KYN28A-12(Z) type indoor armored removable switchgear, suitable for three-phase AC 50Hz, rated working voltage 3.6-12KV power supply system, used for the transmission and distribution of single bus segmented systems that receive and distribute electrical energy Control device. Mainly used in power plants, small and medium-sized generators, power distribution in industrial and mining enterprises and institutions, and power reception and transmission in secondary substations of electrical systems, as well as large high-voltage motor starting. The switch cabinet adopts a middle-mounted structure, which saves about 50% of the space of the circuit breaker's handcart room, which is more conducive to the installation of cables. The protection level of the shell is IP4X. Small size, light weight, reducing floor space. The cabinet shell material is imported aluminum-zinc coated sheet with strong corrosion resistance and oxidation resistance. It has high mechanical strength, which effectively ensures the neatness and beauty of the product, and has the ability to resist internal arc accidents. Safety of operating personnel. The product has a complete "five prevention" function, which can effectively prevent electrical misoperation accidents. It is the mainstream product of the domestic 10kV indoor series.

 

Features

◆The central cabinet of this series is composed of two parts: the cabinet body and the withdrawable part (handcart). A maintenance trolley is also attached for use when the circuit breaker is pulled out. The middle cabinet is a fully assembled structure, and the handcart has the characteristics of small size and light movement, and the whole machine has a strict and reliable interlocking mechanism to ensure safe and reliable use.

◆The shell of the center cabinet is assembled with high-quality aluminum-zinc coated steel sheets after bending, so the assembled center cabinet can maintain the uniformity of dimensions. The middle cabinet is divided into a circuit breaker room, a busbar room, a cable room, and a relay instrument room by a metal partition. Each functional unit is independent; the IP4X enclosure and compartment protection level are fully considered in the design of the switch cabinet. In the event of an arc accident, strict tests have been carried out in accordance with the GB3906 and IEC298 standards, which can effectively guarantee personal safety and limit fire joint operation accidents caused by internal fault arc accidents to the greatest extent.
