Background technology
Isolating switch is in high-voltage switch electric appliance, to use maximum a kind of electrical equipment, as its name suggests, that in circuit, to play the principles and structure of itself of buffer action fairly simple, but because use amount is large, the impact of design, foundation and the safe operation of functional reliability requirement Gao，Dui electric substation, power plant is all larger.The main feature of disconnecting link is without arc extinguishing ability, can only in the situation that there is no load current, not divide, closes circuit.
At present, isolating switch in using on existing market its when mounted, conventionally all can be set with outside a stuffing box, therefore for the situation in stuffing box, staff cannot see clearly in time, after all needing stuffing box to open, the situation that whether puts in place when for example stuffing box inner driving medium closes a floodgate etc. can see clearly, and in maintenance or debugging, be in like manner also the same, complex operation, inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of debugging, easy to maintenance and facilitate staff to observe the isolating switch open type transmission case body of drive disk assembly transmission
For the above-mentioned technical problem of determining, the technical solution adopted in the utility model is: a kind of isolating switch open type transmission case body, and its innovative point is: mainly comprise open type casing, rotating shaft, conductive clip, operation flange, base, extension spring, contact tube;
Described open type casing is mainly that L shaped terminal block forms by the cross section of two busbars that be arranged in parallel and busbar bottom, what between two busbars, be arranged in parallel has two rotating shafts, and vertical setting between two rotating shafts and busbar is respectively arranged with a conductive clip in single rotating shaft;
Described contact tube is divided into contact tube and lower contact tube, and upper contact tube has two, cross-shaped setting, upper end at upper contact tube is provided with voltage equalizing ball, lower contact tube has two, is arranged on respectively in conductive clip, between upper contact tube and lower contact tube, by connector, is connected;
Described connector mainly comprises connecting axle and connecting plate, connecting axle is divided into fixed connection shaft and is flexibly connected axle, described flexible connection axle and fixed connection shaft be arranged in parallel, and being flexibly connected axle is all connected by connecting plate with the two ends of fixed connection shaft, between described flexible connection axle and connecting plate, be flexibly connected, between fixed connection shaft and connecting plate, be fixedly connected with, be flexibly connected axle and be connected with upper contact tube, fixed connection shaft is connected with lower contact tube;
