HGIS-72.5(126)HYBIRED SF6 GAS INSULATING SWITCHGEAR is a new ideal switch manufactured by our company. It has the advantages of GIS, such as compact structure, little occupation, stable reliability, little maintenance and the advantages of AIS, like low price, convenient inspection and repair, lowest influence to the environment. Different to other routine products, it considers substation performance as a whole, and its modularized design can perfectly meet all the arrangement requirement, especially the requirements of newly constructing, extending and modifying to the power station and substation.
HGIS-72.5(126) plug and switch system is also called hybid gas insulated switchgear or half gas insulated switchgear, it is one kind of complete apparatus which is filled with SF6 as insulating and arc extinction medium, and it combines components like circuit breaker, disconnector, earthing switch, built-in current transformer(external current transformer is busbar penetrating type), inlet and outlet line bushing into one earthing metal enclosure. It is applicable to power system with three-phase 50Hz/60hz, rated voltage of 72.5~126kV, and it has the function of opening and closing loading current and short current, coupling, changing-over, controlling, measuring, system-adjusting, safe-insulation to live equipment during overhauling.

Main Characteristics
,,,,.
  Small occupation; light weight; compact structure; bay transportation is available and it is in the leading position in domestic country.
"+",,,3,,20,.
    The incorporated breaker is of self-energized style (pressure and thermal expansion) with a simple and reliable structure, strong breaking capability, short arcing time, long service time, 3 cycles of total breaking time and 20 times of breaking at full capacity.
CT26,,,,10000,"".
The breaker adopts CT26 spring mechanism with a simple and compact structure, high reliability, low maintenance, and long mechanical life up to 10000 times, so it conforms with the "no oil" requirement.
,,,,,,.
The enclosure adopts antirust aluminium alloy material which has advantages of light weight, small loading requirement to the earth, high auti-corrosion ability, small eddy-current loss, low temperature on the enclosure, and high through-current capability.
,,.
 New sealing material which is applicable to withstand high, low temperature and has anti-corrosion ability is adopted to improve the sealing performance of the product.
,,.
  Disconnecting earthing switch can be set on the side of the line, and current transformers can be arranged on both sides of the circuit breaker to guarantee conforming with the domestic design standards.
SF6GIS40%,,,.
  The utilization of the SF6 is only 40% of the GIS, it has low operation noise, low radio interference. So it meets the environmental protection requirement.
,(,,),.
  It can be operated in the toughest environmental conditions, such as places of heavy pollution, frequent hails, high altitudes, frequent earthquakes, hard to dig mountainous terrain and crowded urban districts with limited space.
,,,.

It adopts modularized design idea, and various wiring types such as single busbar, single busbar section-division, double busbar, etc. can be formed.
,.
  Insertion structure is adopted to ensure the convenient and flexible overhauling.
,.
  Preassembling in the company is adopted to greatly shorten the installation and construction period.
,,SF6.
  On-line monitoring to partial discharging, moisture in SF6 and intelligent control technology such as photoelectricity transformer are realized.
