Description
Technical field
The present invention relates to outdoor high-voltage protection apparatus for electric apparatus, and in particular to a kind of disconnecting switch rain cover.
Background technique
High voltage isolator (disconnecting link) is the important component of power grid, play isolated power supply, change system operation mode,
The important function such as grid switching operation are carried out, but the kinematic link for providing driving device to disconnecting link is through mechanism case, due to portion
The design defect of man, subsidiary factory, leakproofness are poor.The leakproofness of mechanism case is especially not sufficient to ensure that in rainy season, the problem is that: one,
Top cover of box design is unreasonable, and top cover is the plane of larger area, is easy ponding, so cabinet is caused to corrode for a long time；Two, it is driven
There is sealing ring in the part that connecting rod passes through the hole on mechanism case top cover, seamed between meeting and kinematic link rotation axis after sealing ring aging
Gap will be poorly sealed because of sealing ring in strong wind heavy rainfall, and rainwater penetrates into inside mechanism case, leads to electricity inside mechanism case
Machine, gear, etc. transmission parts corrode bite, cause disconnecting link position and the failures such as not corresponding from the background；Three, sealing ring is exposed easy to aging
It falls off, the particles such as dust are easily accessible cabinet long time sedimentation in electric appliance unit, make short circuit between secondary component damage, terminal block, very
It refuses point to refuse to close to there is disconnecting link, influences grid switching operation and accident treatment, cause to society's delay power supply or even large-area power-cuts,
Cause huge economic loss.
