Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, the structure of pole in especially a kind of high-pressure vacuum breaker.
Background technology
Pole is as the core parts of circuit breaker, and its insulation property have determined the insulation property of whole circuit breaker.The pole insulation property comprise two aspects, the one, interior insulation property, the 2nd, external insulation performance.The indoor good insulation preformance of 12KV pole vacuum extinction of domestic production can reach power-frequency withstand voltage 60KV/Min, lightning impulse withstand voltage 100KV/Min.Pole arc control device external insulation performance is mainly determined by the creepage distance and the clearance between the conductive pieces of its insulation crust.Be subjected to the restriction of pole installation, overall dimension and accessory size, 12KV pole external insulation level is power-frequency withstand voltage 42KV/Min, impulse withstand voltage 75KV/Min.Can not satisfy the instructions for use of high-insulativity under the special environment for use.In order to satisfy the common method that adopts of specific (special) requirements be: between the connected circuit breaker frame face of the seating plane of pole, add insulating barrier, it is kept apart, increase creepage distance, reach and improve its external insulation level.Though this method is feasible, need to increase correlated parts, increase production cost, increase the production management difficulty.
The utility model content
The purpose of this utility model is to provide a kind of good insulation preformance, pole that reliability is high, satisfies the instructions for use under the particular surroundings, guarantees the vacuum circuit-breaker safe and reliable operation.
The technical solution of the utility model is: a kind of pole of high insulation, comprise the outlet seat, following outlet seat, be flexible coupling, housing, vacuum interrupter, insulated tension pole is wherein gone up the upper end that the outlet seat is installed in housing, and vacuum interrupter is arranged on the inner chamber upper end of housing, the top of vacuum interrupter and last outlet seat overlap joint, the lower end conducting rod of vacuum interrupter is provided with and is flexible coupling, and the other end that is flexible coupling is connected with following outlet seat, and following outlet seat is installed in the lower end of housing top inner chamber, the lower end conducting rod of vacuum interrupter is connected with insulated tension pole, and insulated tension pole runs through the lower part of frame inner chamber.
Further, in such scheme, the described other end that is flexible coupling is fastened on down the end face of outlet seat with metal fastenings.
It is simple and reliable for structure that the utility model adopts, in upper and lower outlet seat centre distance and down under the constant condition of installation dimension such as outlet seat center distance to the ground, distance in the reduction between outlet seat and vacuum interrupter faying surface, to be flexible coupling and change end face into following outlet seat overlapping mode and overlap, increase down the outlet seat and be attached thereto the electric-conductor ground clearance, increase simultaneously down the outlet seat over the ground in the housing along face creepage distance and insulated tension pole outer face creepage distance.Do not increase new parts, technical performance is stable, with low cost, has improved production efficiency and product quality greatly.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is a general 12KV pole structural representation before improving.
Among the figure: the last outlet seat of 1-, the 2-vacuum interrupter, 3-is flexible coupling, outlet seat under the 4-, the 5-housing, 6-insulated tension pole, 7-metal fastenings, the upper and lower outlet seat of D1-centre distance, outlet seat center distance to the ground under the D2-, outlet seat and be attached thereto the electric-conductor ground clearance under the D3-.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 and Fig. 2 compare, Fig. 1 is the pole of the insulation that provides of the utility model, comprise outlet seat 1, vacuum interrupter 2, be flexible coupling 3, following outlet seat 4, housing 5, insulated tension pole 6 is on pole, following outlet seat centre distance D1 and down under the constant part of installation dimension such as outlet seat center distance to the ground D2, last outlet seat 1 is installed in the upper end of housing 5, vacuum interrupter 2 is arranged on the inner chamber upper end of housing 5, the top of vacuum interrupter 2 and last outlet seat 1 overlap joint, the lower end conducting rod of vacuum interrupter 2 is provided with and is flexible coupling 3, and 3 the other end of being flexible coupling is fastened on down the end face of outlet seat 4 with metal fastenings 7; Following outlet seat 4 is installed in the lower end of housing 5 top inner chambers, and the lower end conducting rod of vacuum interrupter 2 is connected with insulated tension pole 6, and insulated tension pole 6 runs through the lower lumen of housing 5.Because the interior insulation and the upper and lower outlet seat of the pole centre distance D1 of vacuum interrupter 2, and outlet seat center distance to the ground D2 can satisfy high insulating requirements down, distance in the reduction between outlet seat 1 and vacuum interrupter 2 faying surfaces, vacuum interrupter 2 is moved on the whole, to be flexible coupling and 3 change end face with following outlet seat 4 into by side overlap joint and overlap, make down outlet seat 4 and be attached thereto electric-conductor ground clearance D3 and increase, housing 5 is interior along the face creepage distance over the ground for outlet seat 4 under also increasing, and improves the insulation property of pole; Meanwhile increase insulated tension pole 6 outer face creepage distances, improve the insulation property of insulated tension pole 6.
The utility model is by increasing following outlet seat and being attached thereto the electric-conductor ground clearance and increasing the outer creepage distance of creepage distance and insulated tension pole in the housing over the ground of outlet seat down, improve the insulation property of pole, do not increase new part, the simple compactness of product structure, technical performance are stablized, do not change between the connected circuit breaker frame face of the seating plane of pole, the production efficiency height is guaranteed the vacuum circuit-breaker safe and reliable operation.
