Description
Technical field
The utility model belongs to high voltage electrical apparatus technical field, is specifically related to a kind of outdoor AC high-voltage vacuum circuit breaker.
Background technology
At present, outdoor AC high-voltage vacuum circuit breaker is mainly applicable to exchange in 50Hz, 40.5kV electric power system, as the use of a deciliter load current, overload current and short circuit current, it both can be used for the control and protection of power plant, transformer station, power equipment and power circuit, also can be used for the place of frequent operation; It is not only applicable to the construction of new electric substation, and is applicable to the use of reforming without oil of old electric substation.But because the structural design of existing outdoor AC vacuum circuit breaker is reasonable not, thus this outdoor AC vacuum circuit breaker exists, and maintenance is not convenient, the defect of mechanical property parameter instability.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provide a kind of structure simple, overhaul outdoor AC high-voltage vacuum circuit breaker that is convenient, stable performance.
For achieving the above object, the utility model adopts a kind of outdoor AC high-voltage vacuum circuit breaker, comprise T-shaped proof mechanism of water case, be arranged on the operating mechanism in proof mechanism of water case, be evenly distributed on three insulated columns on proof mechanism of water case upper surface, arc control device are provided with in described each insulated column, and be provided with fixed contact in each arc control device, described operating mechanism is connected with each insulated column respectively by three groups of transmission mechanisms, described each transmission mechanism includes insulated tension pole, connecting lever, be arranged on the guide rod in insulated column, the lower end interlock of described insulated tension pole is arranged on the link rod on operating mechanism, one end interlock of described connecting lever is arranged in the coupling head of described insulated tension pole upper end, and the other end of connecting lever is arranged on the lower end of guide rod, described guide rod is set with spring base on one end of arc control device, touch spring is provided with in described spring base, the top of described guide rod can with the disconnection of the fixed contact in the divide-shut brake action realization of operating mechanism and arc control device with closed.
The beneficial effects of the utility model are: this outdoor AC high-voltage vacuum circuit breaker have structure simple, overhaul advantage that is convenient, stable performance.The operating mechanism of this vacuum circuit-breaker drives link rod action, and link rod drives insulated tension pole to move up and down, and insulated tension pole drives connecting lever to rotate, thus connecting lever drives guide rod to move up and down, and namely realizes the closed and disconnected of the fixed contact in guide rod and arc control device.And the transmission mechanism of this vacuum circuit-breaker is arranged on the side of insulated column, and this transmission mechanism comprises insulated tension pole, connecting lever and guide rod, and the length of adjustment insulated tension pole and guide rod, what just can adjust this vacuum circuit-breaker opens distance and contacting travel.
