Description
Technical field
The utility model relates to the electric switch technical field, especially relates to and the supporting use of vacuum circuit-breaker, drives to isolate between knife plate and the contact with the elastic force of centering spring to open and close the isolating switch that is electrically connected.
Background technology
Outdoor AC high-voltage vacuum circuit-breaker, especially pole vacuum circuit breaker are widely used in the usefulness that transformer station and industrial and mining enterprises' distribution system and rural power grids do protection and control; The pole vacuum circuit breaker that institute uses and produces at present domestic and international power transmission and transformation industry and the electric power manufacturing scarcely is with isolating switch, though individual product has isolation fracture, the divide-shut brake of isolating switch by manpower control, therefore is subjected to people's subjectivity to influence bigger entirely; The poor reliability of its anti-misoperation mechanism, and volume, weight all obviously strengthen, and causes and use and install inconvenience.
Summary of the invention
The purpose of this utility model is to remedy the defective of prior art, a kind of advantages of compact and light structure is provided, obviously as seen isolation fracture makes accurately opening and closing in place of switch with default elastic force, and and circuit breaker between the supporting isolating switch of pole vacuum circuit breaker of reliable anti-misoperation mechanism is arranged.
For achieving the above object, the technical solution of the utility model is such: the supporting isolating switch of a kind of pole vacuum circuit breaker comprises the underframe shared with pole vacuum circuit breaker summation current transformer, is fixedly installed in insulated leg installing rack and operating axis and the centering spring device, motion arm, insulated tension pole, the insulated leg that are attached thereto on the underframe and is connected parts such as isolation knife plate on the insulated leg; Because of being complementary with three of vacuum circuit-breaker, this isolating switch also has three groups to isolate knife plate, a shared operating axis, on the shaft part of every group of operating axis, be fixed with two connecting rods, one and insulated tension pole bottom are hinged, another connecting rod and centering spring device are hinged, and the centering spring device is to be hinged on underframe, the centering spring device therewith during rod hinge connection at angle; On the said insulated leg installing rack, insulated leg is installed, insulated leg top is fixed with a touch base, and terminal block is installed on the touch base, and hinged one isolates knife plate on the touch base top; The contact of the current transformer that the isolation knife plate other end links to each other with vacuum circuit-breaker is electrically connected; Said insulated tension pole top is hinged with the stage casing that isolates knife plate; The fixedly connected motion arm in the outer end of operating axis; In the underframe outside one interlock plate is arranged, this junction panel links to each other with the drive stay of vacuum circuit-breaker, moves and indentation or stretch out with the divide-shut brake of vacuum circuit-breaker, blocks the motion arm of isolating switch when stretching out.
Owing to adopted technique scheme, the utility model is than prior art, and the structural configuration compact and reasonable is easy for installation, and obviously as seen isolation fracture and when opening circuit, isolates knife plate away from electrical contact, meets people's custom, safe in utilization; During breaking-closing operating, dependent manual operation drives the divide-shut brake action by spring force subsequently to compressing the coupled connecting rod of centering spring in line the time, therefore can accurately not put in place with the manpower factor affecting; Set interlock plate is when the vacuum circuit-breaker closing operation, because of the drive stay interaction energy stretches out automatically with making process, promptly block the motion arm of isolating switch behind the combined floodgate, make its akinesia, have only when the vacuum breaker open operation, interlock plate indentation, the motion arm of isolating switch just can be carried out the divide-shut brake action, can effectively prevent the misoperation that may occur.
