The switch-gear is know for its high reliability, safety, and ease of operation. lt features modulardesign components, including circuit breakers, protection relays, and metering devic.es, which are housed in a robust enclosure. The KYN28A-12 offers comprehensiveprotection and control over the electrical network, ensuring secure and efficient powerdistribution in demanding environments.
Technical parameters
Structure
The switchgear is designed according to the armored metal-enclosed switchgear inGB3906-91.The rectifier body is composed of two parts:the cabinet body and the centrawithdrawable part (handcart).The cabinet is divided into four separate compartments,and theprotection level of the outer shell is IP4X and it is IP2X when the door of each small room andthe door of the circuit breaker is opened.With overhead incoming and outgoing lines,cableincoming and outgoing lines and other functional schemes,it can be a power distributiondevice in various schemes after arrangement and combination.The switchgear can beinstalled,debugged and maintained from the front,so it can be double-arranged back to backand installed against the wall,which improves the safety and flexibility of the switchgear andreduces the floor space.

HXGN61-12 (SF6) Overview
The HXGN-12(SF6) ring main unit (RMU) is a type of compact, metal-enclosed switch-gear used in 12kV power distribution networks. lt is typically used in urban and ruralpower distribution, industrial power distribution, and compact substations. The HX-GN-12(SF6) RMU is designed for reliable power distribution and protection, offeringfeatures like load break switches, circuit breakers, and protection relays. lts compactsize and robust design make it suitable for installation in confined spaces, providing asafe and efficient solution for secondary power distribution networks. The RlU en-sures minimal power interruptions and ease of operation and maintenance.
Technical parameters
Structutal features and working principle
This ring network type cabinet makes air as the insulating medium and it is mainly assembled with ZFN 口-10/630 type vacuum load switch. And there are two cabinet schemes-incoming cabinet and outgoing cabinet.
1. Incoming cabinet scheme
There is a ZFN 口-10/630 type vacuum load switch on the main circuit inside the cabinet with isolating knife, and grounding knife. They are all installed in one machine stand and they areinter locked, realizing the connection of three working stations of busbar, isolation and grounding. Inside the cabinet, components such as CT, PT can be installed flexiblv.
2. Outgoing cabinet scheme
There is a ZFN -10/630 type vacuum load switch, fuse with striker (used as isolating switch)and grounding knife on the main circuit inside cabinet, and the three working stations operation can be realized. Inside the cabinet the componments such as CT/PT and ZNO ar.rester can be installed flexibly, so the metering cabinet can be removed. nside the incomingcabinet and outgoing cabinet, there is insulating protecting baffle interlocked with grounding switch. And inside the cabinets, the mechanical interlocks are adopted between each switchand baffle as well as the cabinet door with the requirement of “five-prevention”and iP2X of theprotection degree of the cabinet enclosure.
