Xgn15-12 sulfur hexafluoride(SF6)high voltage ring network cabinet is a kind of compact and expandable switch equipment suitable for distribution automation system.The adoption of sensing technology and the latest protection relay makes the switch cabinet qualified even for hospitals and airports with demanding operation requirements.
This switch meets the requirements of iec420-1990,GB3906 and other standards,and has the function of preventing the load switch from closing,preventing the grounding switch from closing the load switch and the interlock of the lower door when it is in the closed position.
Design description
1.Load switch unit fln36-12
The switch cabinet can be divided into monomer,monomer,double pipe outlet,2 units,3 units,4 units,5 units of standard and in line with side casing type,load switch main circuit part sealed by epoxy resin made of APG process casting insulation shell,the insulation shell with good insulation performance,simple structure,convenient installation,safe and reliable.Each unit has an independent intervals,the top of the bus connection,can above multi-cell and cabinet.
The standard configuration
Mixer 630 a bus
◆three-station load/ground switch
Spring operating mechanism
◆position indication of load switch and ground switch
◆incoming/bus voltage indicator(single or bus extension type)
◆outgoing voltage indicator
◆all switch functions can be added to the panel padlock mode to achieve control
◆the interlock between the grounding switch and the cable room door
Mixer SF6 barometer
◆grounding copper bar
Optional configuration
◆short circuit and ground fault indicator
◆current transformer and ammeter for measurement
◆measuring current transformer
Switch position key lock
◆electric operation mechanism
2.Cable branch box load switch unit
The load switch to cable branch box dedicated development and design,can be divided into single left into line,single casing pipe line on the right side,the main loop of the load switch part sealed by epoxy resin made of APG process casting insulation shell,wire loop can be divided into four most road,therefore,relatively simplified structure,easy to install,more secure;The SF6 load switch makes the single switch cable branch box smaller,easier to install and more reliable.
The standard configuration
Mixer 630 a bus
◆three-station load/ground switch
Spring operating mechanism
◆position indication of load switch and ground switch
◆incoming/bus voltage indicator
◆outgoing voltage indicator
◆all switch functions can be added to the panel padlock mode to achieve control
Mixer SF6 barometer
◆grounding copper bar
Optional configuration
◆short circuit and ground fault indicator
3.Load switch fuse combination electrical unit
The integrated electrical unit is used for transformer protection of 1250KVA and below capacity.This unit is load switch ring network cabinet with fuse.When the grounding switch is closed,the lower side of the fuse will be grounded at the same time,and the safety isolation between the upper side of the fuse and the power supply will be realized to ensure the safety of personnel when replacing the fuse.In order that the fuses in one phase will not cause the electrical equipment to run out of phase,this unit is equipped with a tripping linkage mechanism.When the tripping observation window shows red,it means that the tripping device ACTS or the fuse breaks and trips.This unit can be combined with other units to realize ring network power supply.
The standard configuration

◆three-station load/ground switch
Spring operating mechanism
◆position indication of load switch and ground switch
◆incoming/bus voltage indicator(single or bus extension type)
◆outgoing voltage indicator
◆all switch functions can be added to the panel padlock mode to achieve control
◆the interlock between the grounding switch and the cable room door
Mixer SF6 barometer

◆external bus
4.Vacuum circuit breaker unit
Adopt spring-type vacuum circuit breaker:the mechanical life can reach 10000 times;(fast protection action,no more than 30ms breaking time),easy to achieve level difference.Upper and lower disconnecting switches can be configured.Vacuum circuit breaker and isolation switch adopt mechanical interlock,provide visual isolation break,flexible collocation,the whole system is air insulation.
The standard configuration
Mixer 630 a bus
◆630A fixed vacuum circuit breaker module(VS1)
◆controller CM(DC/AC/220/48/24v operating power supply)
◆isolation switch(GN30,GN19)
◆automatic power supply and external power supply microcomputer integrated protection device(grt-y200,grt-z100)
Mixer protection CT
◆grounding and cable bin door locking
◆auxiliary contact of vacuum circuit breaker switch position:2NO+2NC
◆operating power supply(including power supply PT,power module,backup battery)
Optional configuration
