XGN74-12/630(J200)-20 Type Ring Main Unit
(with branch fast plug in & out function)-Node Cabinet
XGN74-12/630(J200)-20 Type Ring Main Unit (with branch fast plug in & out function)-Node Cabinet has a group of main lines with three-position load switchgear. The main circuit is equipped with the traditional functions of SF6 insulated metal enclosed switch and anti-misoperation interlocking function. The node cabinet can also be equipped with a group of branching line with three-position load switchgear. The branching line has one side rapid plug in & out function. Thus, with similar floor arear, this kind of node cabinet can replace SF6 insulated metal enclosed switch. Meanwhile, the number of reserve cabinets is increased. The node cabinet has three main functions:
1. The node cabinet can realize bypass repair when the circuit is in service.
2. It can realize temporary power taking when the circuit is in service.
3. We can carry out insulation test for the ring main unit and cables without opening the door of the unit and removing the terminal of the cable. So the failure checking and scheduled testing can be satisfied.
● The node cabinet can meet normal functions of LBS Cabinet;
● It can provide temporary power supply or power distribution;
● It can realize both sides cable phase checking to prevent safety accidents caused by phase lacking or phase difference;
● Low gas pressure latching function can be realized, avoiding low pressure mal-operation;
● Manual latch system can be used to avoid mistake operation;
● Full sealed case structure can be used to solve rusting issues inside operating mechanism.
● Fast plug in cable can be used as terminal interface, improving reliability of cable installation.
