Product Description
Specifications switchegear:
1.Easy installation and maintenance-free
2.Full-sealed&all insulated
3.Top ten Switchgear manufacutre&ISO9001
1.Feautre and benefits: 1.7kv to 36kv are available 2. All insulated and full-sealed 3.Compact and modular design 4, Flexible and smart 5 .Ease of installation and maintainance-free 6 .Ease and safe to operate 2.Description The SF6 Ring main unit is made up of modular units containing fi xed, disconnectable orwithdrawable metal-enclosed switchgear, using sulphur hexafl uoride (SF6) or vacuum. The SF6 Ring main unit are used for the MV section in MV/LV Transformer substations in publicdistribution systems and MV consumer or distribution substations up to 36 kV. HXGN series SF6 units are designed for indoor installations. Their compact dimensions are: a.375 to 1500 mm width
b.1600 to 2250 mm height
c. 840 to 1400 mm depth
this makes for easy installation in small rooms or prefabricated substations.Cables are connected via the front.
All control functions are centralised on a front plate, thus simplifying operation.The units may be equipped with a number of accessories (relays, toroids,instrument transformers, Surge Arrester, control and monitoring, etc.). 3.Normal operating conditions
Ambient air temperature:
1) less than or equal to 40°C
2) less than or equal to 35°C on average over 24 hours
3) greater or equal to –5°C.
Altitude
1) less than or equal to 1000 m
2) above 1000 m, a derating coeffi cient is applied (please consult us).
Solar radiation
1) no solar radiation infl uence is permitted.
b Ambient air pollution
1) no signifi cant pollution by dust, smoke, corrosive and/or fl ammable gases,
vapours or salt.
Humidity
1) average relative humidity over a 24 hour period, less than or equal to 95%
2) average relative humidity over a 1 month period, less than or equal to 90%
3) average vapor pressure over a 24 hour period, less than or equal to 2.2 kPa
4) average vapor pressure over a 1 month period, less than or equal to 1.8 kPa.
For these conditions, condensation may occasionally occur. Condensation can be
expected where sudden temperature changes occur in periods of high humidity.
To withstand the effects of high humidity and condensation, such as breakdown of
insulation, please pay attention on Civil Engineering recommendations for design
of the building or housing, by suitable ventilation and installation. 4.Electrical characteristics
5.Compartments description a. Busbar compartment The three insulated busbars are parallel-mounted. Connection is made to the upper pads of the enclosure using a field distribution with integrated captive screws. b. Switch compartment This compartment is separated from the busbar compartment and the connection compartment by the enclosure surrounding the switch, the disconnector and the earthing switch. c. Connection and switch compartment d. Operating-mechanism cover These covers contain the various operating functions for the:switch and earthing switch,disconnector(s),Circuit Breaker,contactor and the voltage presence indicator. 6. Cetification ISO9001:2008 ISO14001:2004 ABB authorized certificate Schnieder authorized certificate 7. Ordering Instructions
