Classification, types and common models of 10KV high voltage switchgear

1. Classification of 10KV high voltage switchgear:
According to the cabinet structure, 10KV high voltage switchgear can be divided into four categories: metal closed interval switchgear, metal closed armored switchgear, metal closed box switchgear and open switchgear.
A. Metal enclosed spacer switchgear (denoted by the letter J) : Similar to armored metal enclosed switchgear, its main electrical components are also installed in separate compartments, but with one or more non-metallic partitions conforming to a certain level of protection.
Such as JYN2- type high pressure switch cabinet.
B. Metal enclosed armored switchgear (represented by letter K) : the main components (such as circuit breakers, transformers, busbars, etc.) are respectively installed in the grounded metal enclosed switchgear in the compartment separated by metal partitions.
For example: KYN28A- type high voltage switch cabinet.
C. Metal closed box switchgear (represented by letter X) : switchgear whose shell is metal closed switchgear.
Such as XGN2- type high voltage switch cabinet.
D, Open switch cabinet: no protection grade requirements, part of the shell is open switch equipment.
Such as GG-1A(F) type high voltage switch cabinet.
Commonly used 10KV high voltage switch cabinet model

2. Types of 10KV high voltage switchgear
10KV high voltage switch cabinet if divided by type, can be divided into central cabinet, ring network cabinet, box change, four categories.
A, central cabinet.
Central cabinet is called metal armored central removable switch equipment.
It is a high voltage power distribution device, with the highest working voltage of 3.6/7.2/12kV. It is a complete set of indoor power distribution device of three-phase AC 50Hz single bus segment system or double bus segment system.
Common 10KV central cabinet models are KYN-28, KYN44-12 and so on.
B. Ring network cabinet.
Ring network cabinet (Ring Main Unit) is a set of high voltage switchgear in metal or nonmetal insulation made assembling interval type Ring network cabinet put oneself in another’s position inside or the electrical equipment of the power supply Unit, its core part USES the load switch and fuse, has the advantages of simple structure, small volume, low price, can improve the power supply parameters and performance and safety, etc.
C. Box change.
Box-type substation is a kind of high voltage switchgear, which is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil construction power distribution room and power distribution station, and becomes a new complete set of transformer and distribution devices.

3, common 10KV high voltage switch cabinet model
A, KYN28A-12 central cabinet, KYN28A-12 central cabinet, also known as indoor metal armored pull out switch equipment is mainly used for power plants, industrial and mining enterprises distribution and power system of the secondary substation of the power receiving, power transmission and large motor starting.
For control, protection, real-time monitoring and measurement purposes.
Have perfect five defense function.
B, HXGN17-12 Ring network cabinet: HXGN17-type high voltage switch cabinet (referred to as ring network cabinet), three-phase ac rated voltage 10kV, rated frequency 50Hz indoor box type AC metal closed switch equipment.
Suitable for factories, workshops, residential, high-rise buildings and other places of power distribution system, ring power supply or double power supply radiation power supply system, play the role of acceptance, distribution and protection, also suitable for box substation.
C, XGN2-12: XGN2-box type fixed metal closed switch equipment, is used for 3-10kV three-phase AC 50Hz as a single bus and single bus segment system to receive and distribute electric energy device, especially suitable for frequent operation places.
It is mainly used for power plant, industrial and mining enterprise distribution, secondary substation of power system and starting of large motor, etc.
Implement control, protection, real-time monitoring and measurement.
Cabinet body for the full assembly type structure, with perfect five defense functions.
D. Fixed high voltage switchgear is suitable for receiving and distributing electric energy in 3-10KV three-phase AC 50Hz system, and has the functions of controlling, protecting and monitoring the circuit.
The bus system is single bus and single bus section.
