Abstract

The invention discloses a main bus chamber with a stripping function without power failure of a ring main unit. The main bus chamber comprises a cabinet top box mounted at the top of a switch cabinet, two groups of static contact sleeves arranged in the cabinet top box, and a movable door device arranged in the cabinet top box, wherein each group of static contact sleeve comprises a contact shell fixed at the top of the switch cabinet and a static contact arranged inside the contact shell; the static contact is connected with a main bus in the switch cabinet; the movable door device comprises a bracket, two groups of movable door guide rods arranged on the bracket, two groups of horizontal movable doors which can slide along the movable door guide rods, and transmission pieces driving the movable doors to slide; the two ends of each group of movable door are respectively connected with the transmission pieces; each transmission piece is arranged on the bracket; and when each group of movable door is reset, the static contact sleeves correspond to one another up and down. The main bus chamber disclosed by the invention has the advantages of small size, accuracy for guiding, reliability for transmission, foldable storage of the movable doors, in-position protection, simplicity in operation and reliability in connection.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a main busbar room of the ring network cabinet with the function of adding and dismantling cabinets without power failure. Background technique [0002] In the normal production of power supply enterprises, the reliability of power supply is mainly affected by two aspects: fault power outage and planned power outage. Due to the improvement of the power grid construction level, the probability of power outage due to failure has been greatly reduced, so reducing the time of planned power outage has become an important factor affecting the reliability index of power supply. Planned blackouts include power cuts, capacity increases, various maintenance and construction blackouts, etc. At this stage, with the large-scale operation of new fully insulated and fully sealed ring network cabinets, there are more and more opportunities to add cabinets to ring network cabinets,...
