Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, refers in particular to a kind of miniaturization high voltage permanent vacuum breaker module.
Technical background
Along with the development of China's miniaturization high-tension switch cabinet, must development of miniaturized high voltage permanent vacuum circuit-breaker to satisfy the requirement of miniaturization high-tension switch cabinet.At present, the miniaturization switch cubicle selected for use in operation of power networks of China has XGN15-12 and XGN68-12 type high-tension switch cabinet.But the main switch of these switch cubicles is mainly selected sulphur hexafluoride on-load switch and side shock mount operating mechanism formula vacuum circuit-breaker for use.The sulphur hexafluoride on-load switch need charge into the sulfur hexafluoride gas of call prohibition use in the world.Sulphur hexafluoride on-load switch and the common shortcoming of side shock mount operating mechanism formula vacuum circuit-breaker are: at long-time on/off switch or be subjected to the influence that extreme climate expands with heat and contract with cold, therefore its trip gear can cause wearing and tearing or be out of shape malfunctioningly, cause unnecessary power outage.Therefore, domestic most of high-tension switch cabinet manufacturer all adopts the miniaturization permanent magnetism vacuum breaker module of the ISM-12 that German Te Ruide company produces.The miniaturization permanent magnetism vacuum breaker module of the ISM-12 that Germany Te Ruide company produces adopts three permanent magnet mechanisms of three-phase.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of miniaturization high voltage permanent vacuum breaker module is provided.
For achieving the above object, the solution that the utility model is taked is: a kind of miniaturization high voltage permanent vacuum breaker module, insulated tension pole is set on the framework, conductive strips are set on insulated tension pole, conductive clip is set on conductive strips, the insulated tension pole upper end is in the vacuum tube, by the copper flange conductive strips are connected with busbar, fixed insulation tube on the framework, insulated tension pole and vacuum tube are in the insulating cylinder, the vacuum tube upper end is fixed by nut, excess of stroke spring external member is set in the framework, excess of stroke spring external member is connected with insulated tension pole, the splined shaft that a permanent magnet mechanism also is set in the framework and can rotates, and permanent magnet mechanism is connected with mechanism's connecting lever, mechanism's connecting lever connects splined shaft, splined shaft connecting lever one end connects splined shaft, the other end connects the connecting lever connecting plate, and the connecting lever connecting plate other end connects output toggle arm, and the output toggle arm other end connects excess of stroke spring external member.
The utility model has been owing to adopted permanent magnet mechanism and subtracted force transmission mechanism, with regard to not existing in long-time on/off switch or being subjected to the influence that extreme climate expands with heat and contract with cold and causing wearing and tearing or be out of shape malfunctioningly, causes the problem of unnecessary power outage.Its operation principle is as follows: horizontal pushing mechanism connecting lever when permanent magnet mechanism moves, and mechanism's connecting lever clockwise rotates splined shaft, and the splined shaft connecting lever also clockwise rotates simultaneously; When permanent magnet mechanism moved to closing position, splined shaft connecting lever and connecting lever connecting plate were in alignment, this moment the output toggle arm left end move downward, right-hand member moves upward, excess of stroke spring external member also moves upward, and promotes insulated tension pole vacuum tube is closed a floodgate; When splined shaft connecting lever and connecting lever connecting plate were in alignment, the counter-force of excess of stroke spring external member 80% was born by splined shaft, and remaining counter-force is just born by permanent magnet mechanism, reduced the confining force that the needs of permanent magnet mechanism are born widely.
The utility model three-phase has only a permanent magnet mechanism and mechanism's connecting lever, by splined shaft three cover transmission components (splined shaft connecting lever, connecting lever connecting plate, output toggle arm) can be set, and makes the three-phase divide-shut brake, and therefore, framework (mechanism's casing) can be made forr a short time.
