Abstract
The utility model relates to a generator glass steel end hoop structure, end hoop structure includes that garter spring and end hoop connect, go side hoop articulate between the garter spring, adopt to dismantle between the garter spring connects with the end hoop and be connected, the garter spring surface is equipped with the insulated paint layer. The utility model discloses simple structure, reasonable in design, not only simply but also practical, its performance requirement accorded with the generator technology requirement. The utility model discloses the deformation that not only can less cast garter spring produces in welding process, when the generator need be maintained, the garter spring can be dismantled, and used repeatedly saves the cost, in addition, still have advantages such as insulating properties is good, manufacturing process simple, low in manufacturing cost, implementation convenience.
Description
Technical field
The utility model relates to a kind of stator end hoop structure, especially relates to a kind of generator fiberglass end cuff structure.
Background technology
End hoop is a vitals in large-sized water turbine generator stator, to connect into diameter by some butt garter springs be 4000mm ~ 25000mm(differing in size according to hydraulic generator capacity to end hoop) an annulus, for a fixture at colligation stator bar two ends.
Hydraulic generator stator end cuff structure of the prior art generally comprises cast garter spring and end hoop joint, and between cast garter spring and end hoop joint, the general welding manner that adopts connects.Its Problems existing is, existing welding manner, although make cast garter spring firmly be fixed on end hoop joint, not quick detachable, safeguard inconvenient, and welding manner connects, and easily makes cast garter spring be out of shape, causes it to use.
In addition, traditional generator end hoop generally adopts stainless steel structure, and insulation property are bad, need partly repeatedly bag mica paper tape and dipping lacquer glass tape, complex structure, and cost is high.
Utility model content
In order to overcome the deficiency that prior art exists, the utility model provides that a kind of structure is simple, good insulation preformance, be convenient to the generator fiberglass end cuff structure changed, cost is low.
A kind of generator fiberglass end cuff structure, described end cuff structure comprises garter spring and end hoop joint, and connected by end hoop joint between described garter spring, adopt between described garter spring and end hoop joint and removably connect, described garter spring outer surface is provided with insulating lacquer layer.
As preferably, be fixedly connected with by trip bolt between described garter spring with end hoop joint.
As preferably, described trip bolt is arranged along the circumference of garter spring.
As preferably, be connected by countersunk head pin between described garter spring with end hoop joint.
Removably connect and avoid garter spring produce distortion in welding machine process, can refitting be dismantled, not only easy to use, and saved cost.
As preferably, the fit clearance that described garter spring binds round joint with end is 0.08 ~ 0.12mm.
As preferably, described garter spring is cast garter spring.
The utility model structure is simple, reasonable in design, and not only simple but also practical, its performance requirement meets generator techniques requirement.The utility model not only can the distortion that produces in welding process of less cast garter spring, and when generator needs to safeguard, garter spring can be dismantled, and reuses, and saves cost; In addition, the advantage such as also have that good insulation preformance, manufacturing process are simple, low cost of manufacture, enforcement are convenient.
