MV Gas Insulated Switchgear Panel Descriptions:

· MV Gas insulated Switchgear Panel, referred to as C-GIS, is an expansion of high-voltage GIS products in the medium-voltage field. It uses low-pressure SF6 gas, N2 gas or mixed gas as the insulating medium of the switchgear, uses vacuum or SF6 as the arc-extinguishing medium, and concentrates and seals medium-voltage components such as busbars, circuit breakers, and isolating switches in the box. High-tech products integrating intelligent control, protection, monitoring, measurement and communication are produced by using modern insulation technology, breaking technology, manufacturing technology, sensing technology and digital technology. It has the advantages of small size, light weight, good safety, high reliability, and can be used under harsh environmental conditions.

· The reason for using GIS is: in the high-voltage system, the use of separate elements requires a large distance between each phase, and hydropower stations are mostly located in mountainous areas, and it is difficult to find large flat land. Due to the small size of GIS, this problem can be solved very well.

· Air insulated switchgear for utility and industry, covering also highly demanding applications, such as data centers, oil and gas, mining, marine and nuclear power. A wide choice of products designed as per IEC, ANSI, CSA, ENA, GB, GOST and other standards.

UniGear primary switchgear:The UniGear family of IEC switchgear and motor control centers for primary distribution offer a unique opportunity by freely combining different types of panels (UniGear ZS1, UniGear 550, UniGear 500R and UniGear MCC) in to the same switchgear, giving the highest flexibility while optimizing footprint. The new intelligent UniGear Digital solution maximizes benefits by using sensors and IEC 61850 based technologies.

· UniSec secondary switchgear:For secondary applications, the highly innovative UniSec range of IEC switchgear offers standardized modules and panels with fused switch-disconnectors and circuit breakers, also with dedicated Smart Grid solutions.

MV Gas Insulated Switchgear Panel Advantage:

· Maximum safety

· Each functional compartment is completely independent

· High pressure parts are completely sealed

· High voltage components are not affected by external pollution

· Insulation performance is not affected by site altitude

· Minimize size(Space savings of up to 70% compared to conventional switchgear)

· More convenient operation

· Longer service life, not affected by the environment

· Fewer maintenance requirements means maximum savings in operating costs

· Longer service life than other switchgear, thus saving new investment

· The saving of infrastructure land and space greatly reduces the total investment and operating costs.

MV Gas Insulated Switchgear Panel Applications:

· Generate electricity

· Power distribution

· Use electricity

MV Gas Insulated Switchgear Panel design:

· Laser welded, stainless steel plate housing

· Modular design

· No need for gas recovery or replenishment during on-site consolidation operations

· Dedicated pressure release channel

Internal cone cable entry system

SF: gas insulation:

· The busbar room is a sealed air room

· The circuit breaker chamber is a sealed air chamber

MV Gas Insulated Switchgear Three position switch:

A stick switch driven by a motor with three functions:

· Connection, isolation and grounding

· The middle position is an isolated position

· extreme position

· Isolation switch "closed" or grounding switch "closed"

· Any operation needs to be carried out without current, that is, when · · the circuit breaker is opened

· Only a few moving parts in the air chamber

Operating mechanism outside the gas chamber:

· The contact slider is driven by the motor turning the insulated shaft

· Emergency manual operation with optional mechanical lock

· A position can be detected by sensors or auxiliary switches

· with mechanical position indicator

VD4X circuit breaker:

· Circuit breaker poles placed horizontally

· The operating mechanism is outside the gas chamber

· The pull rod between the pole of the circuit breaker and the · mechanism moves back and forth

· Sealed sleeve connection

· Cooperate with the three-position switch to realize the grounding function

· Circuit breakers are of higher quality than earthing switches

· More operations can be performed on faults

· Vacuum breaking does not cause deterioration of SF gas

MV Gas Insulated Switchgear Control Scheme:

· user-specified multifunction device

· REF542plus includes all overcurrent and distance protection

· separate protective device

· Prevent misuse

· logic programmable

· Optional electromechanical misuse protection

· Mechanical interlock between circuit breaker and three-position switch (optional)

· Advanced proximity or auxiliary switches

· Density sensors monitor the gas pressure in each chamber

· Fast trip on internal arc fault (optional)

· Current/voltage measurement selectable

· Sensors in the gas chamber

· Current Transformer in Gas Chamber

· voltage transformer

· External plug-in type to prevent accidental contact with high-voltage parts

· According to different protection and control units, flexible way to connect with the automation system.

MV Gas Insulated Switchgear Panel Transport Packaging:

· Our container type compact substation is desined for easy transportation and fast installation. Which is pre-assembled for easy set-up and commissionin.All components type-tested.

· Package substation is prefabricated substation; ready for installation at site. Package substations are most preferred solutions nowadays as there are Concerns regarding space, aesthetics and safety.Much more safety for the public and operators compared to traditional civil works substations.
