Indoor AC Hv Sf6 Power Distribution Switchgear

Model NO.: HXGN-40.5(F)(F. R)/630-20 50-31.5 Installation: Indoor High-voltage Phase: 3 Phase Transport Package: Wooden Cases Origin: Ningbo China Type: Low-voltage Frequency: 50Hz Trademark: CNVILLE Specification: iEC CE, ISO HS Code: 85
General:
    HXGN-40.5(FF. R)/630-2050-31.5 Indoor HV SF6 Switchgear(here in after shorted as "RMU")is a 50Hz AC three-phase indoor HV Power Distribution equipment. It is a combination electrical apparatus with hold switch and ground connection switch and the bus of his return circuit seal up in the metal case aspect, adopting spring conduce motive construct, with SF6 gas regards to arc and insulation dielectric. It is suitable in40.5kV ring supply of Power Supply circuit or double radiation power feed promptly when the circuit breaks down, having raised the reliability and utilization ratio. Especially is suitable in power supply load density greatly and the industry business zone or rural area villages and towns of cable feed network. At the same time RUM is safety in use, not bullied waits influence, installs easy, keeps in repair few and save place, and is fit for loading in box type substation very much, load switch or the load switch-fuse combination the electrical apparatus in RMU also can be used as complete switchgear by self.
 
Structure:
    The switch room forms by the bus sealed up between ability return circuit ( including load switch and ground connection switch) and his return circuit of metal case aspect. The outer covering is welded by 3mm's cold rolling steel plate. Every ability return circuit includes a load switch and a ground connection switch. The load switch is formed by the moving finger system of perpendicular moving and the still finger located down, when the switch floodgate, moving finger move downward and the load switch is put through. Ground connection switch is formed by moving and still knife, and after the spring is crossed, ground connection switch is out through quickly. There are 4 rectangle assembly process holes in top and back of switch room, and the observation window is loaded in the face of RMU, and can see "branch" and "close" of ground connection switch. The explosion proof device is loaded in back of RMU.
    Load switch adopt the calm blowing inside type structure, it is strong in extinguish arc and just not influencing alternate and the insulation to the earth, moving and the still finger both have the arc finger, and has raised greatly in opening and breaking times.
    The transformer protection return circuit is formed by fuse and the load switch room, the high pressure limit stream fuse is loaded in insulation shell aspect that poured by epoxy, after the fuse fusing , flick the pin and the load switch divides the floodgate.
    Operating structure room is located in the face of RMU, in every ability return circuit, load switch process manpower or motor-driven energy storage spring structure, ground connection switch allocates manpower energy storage spring constructs, the face has operation hole to be used in load combined floodgate, and directive light of branch or combined floodgate an d motor-driven branch or combined floodgate button and has the imitation thread, switch situation display plate and locking seat, the operation of load switch and ground connection switch possesses the interlock device in order to prevent the glitch.
