Description
Technical field
The utility model relates to high voltage electrical apparatus technical field, especially relates to a kind of Novel vacuum circuit breaker.
Background technology
In High-Voltage Electrical Appliances field, high-pressure vacuum breaker is the core component in complete equipment of high voltage switch, is the electric equipment for control and protection electric power system.Vacuum circuit-breaker mainly comprises vacuum interrupter, operating mechanism and support, vacuum interrupter and operating mechanism are all arranged in frame, need the circuit access vacuum interrupter of break-make, vacuum interrupter mainly comprises the porcelain shell playing insulating effect, fixed contact and moving contact, the moving contact of operating mechanism and vacuum interrupter is connected, connection between the upper moving contact of control vacuum extinction indoor, disconnect, thus realize circuit breaker and close and turn-off current, vacuum short-circuiting device product product structure common is at present complicated, assembly work is loaded down with trivial details, the current transformer changed during maintenance on product is inconvenient.
Utility model content
For the deficiencies in the prior art, the utility model discloses a kind of Novel vacuum circuit breaker, this product need not increase casing, and Product Assembly is simple, changes current transformer convenient during maintenance.
To achieve these goals, a kind of Novel vacuum circuit breaker that the utility model provides, comprise circuit breaker case, casing is provided with vacuum circuit breaker body, isolation switch, casting type current transformer and support and be flexible coupling, described vacuum circuit breaker body and isolation switch one are installed, mechanical interlocking is had between vacuum circuit breaker body and isolation switch, described support installing is at vacuum circuit breaker body outgoing line side, current transformer is installed on support, screw rod is adopted to be connected between current transformer with support, vacuum circuit breaker body is provided with operating mechanism and conducting rod, conducting rod is connected with being flexible coupling with current transformer, the described employing red copper foil that is flexible coupling is flexible coupling.
The vacuum circuit-breaker beneficial effect that the utility model provides is that vacuum circuit breaker body and current transformer one are installed, current transformer adopts outdoor poured with epoxy resin type current transformer, be specially adapted to little no-load voltage ratio vacuum circuit-breaker, casing need not be increased, Product Assembly is simple, change current transformer during maintenance convenient, well compensate for deficiency of the prior art, be worth of widely use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, vacuum circuit breaker body; 2, isolation switch; 3, current transformer; 4, be flexible coupling; 5, conducting rod; 6, operating mechanism; 7, support; 8, casing.
