Abstract
The invention discloses a directly-connected transmission mode, which comprises a mechanism, a shell, a shaft seal, an insulated pulling rod and an O-type sealing ring, and is characterized in that the mechanism output shaft is directly connected with the transmission shaft of an isolation switch. Setting of a complicated external connection rod and a crankshaft can be avoided, the fewest of transmission parts between the mechanism and the isolation switch and the maximum of the transmission efficiency are met, the transmission mechanism is sealed in the O-type sealing ring, the weather resistance of the transmission system is enhanced, the mechanical performance of products is improved, and the product reliability is enhanced.
Description
Technical field
This technology refers to a kind of drive mechanism of high-voltage switch gear technical field, is particularly used for gas insulation metal seal combined electrical apparatus
(
Referred to as
GIS)
The mechanism of middle disconnecting switch and body power transmission shaft are directly connected technology.
Background technology
Tradition
GIS
The disconnecting switch of middle three-phase adopts same mechanism, and by external connecting rod and connecting lever the breaking-closing operating of disconnecting switch is realized, while in order to block the electric link between three-phase, pull bar between phase and phase also needs to arrange insulation system.To realize three-phase synchronous, need to couple together to form an entirety with same mechanism by complicated external connecting rod and connecting lever between three-phase, so not only reduce the transmission efficiency of mechanism, and the external connecting rod and connecting lever of complexity are exposed in atmospheric environment, running part can produce corrosion or other impurity interference because of ambient influnence, be that the normal operation of equipment leaves hidden danger.
The content of the invention
This technology is directed to deficiencies of the prior art, there is provided a kind of mechanism's direct connection technology, the folding of disconnecting switch is realized, in being applied to gas insulation metal seal combined electrical apparatus.Mechanism's output shaft is directly directly connected with disconnecting switch power transmission shaft, it is to avoid complicated external connecting rod and connecting lever is arranged, and not only meets that drive disk assembly between mechanism and disconnecting switch is minimized, and transmission efficiency is maximized, and transmission system is enclosed in
O
In type sealing ring, with atmospheric isolation, increase the weatherability of transmission system, improve the mechanical performance of product, increased the reliability of product.
This technology is achieved through the following technical solutions, and the present invention includes：Mechanism, housing, sealing, insulated tension pole,
O
Type sealing ring.Wherein：Mechanism is directly connected with shell flange face, passes through
O
Type sealing ring is closed, and mechanism's output shaft of the inside is connected with disconnecting switch power transmission shaft by spline, then by drive mechanism drive disconnecting switch moving contact realizes folding again.
Described drive mechanism includes：Sealing, insulated tension pole, wherein：Insulated tension pole is arranged between moving contact.
During work, when needing to carry out disconnecting switch combined floodgate, operating mechanism actuating sealing, sealing drives insulated tension pole, insulated tension pole to drive moving contact movement by spline, mutually close with quiet sidepiece part by spline, forms the "on" position of disconnecting switch；When the separating brake for realizing disconnecting switch is needed, operating mechanism actuating sealing, sealing drives insulated tension pole, insulated tension pole to drive moving contact movement by spline again, be separated with quiet sidepiece part by spline, forms the gate-dividing state of disconnecting switch.
