Abstract
The present invention provides a kind of outdoor inflatable mechanism case for power system; overcome the deficiencies in the prior art part; using inflatable all-sealed structure so that be in normal pressure state in mechanism case body all the time, reduce its inner member; such as button, heater and its temperature and humidity control device; and the component for causing it internal is at anaerobic state, isolate with moisture, oxygen etc., the non-maintaining structure of formation; the component in casing can be effectively protected, maintenance can be greatly reduced again.To be with more revolutionary meaning.
Description
Technical field
The invention belongs to power system high-tension apparatus field, and in particular to a kind of outdoor inflatable machine for power system
Structure case.
Background technology
Mechanism case is equipped with greatly for outdoor high-voltage electric appliance equipment in power system, and mechanism case is switchgear（Main bag
Include breaker and disconnecting switch）Operating mechanism, for driving switch equipment breaking-closing operating.According to the difference of its product, its
Inner member is different.It is common, the secondary component composition such as major motor and contactor, button inside isolating switch mechanism case,
Circuit breaker mechanism case is more relative complex, is mainly made up of the secondary component such as running part and relay, button.Existing machine
Structure case multidigit is hanging, is connected by kinematic link with switchgear body.
Power system open air mechanism case it is very many, existing structure be can free open-type, equipped with chamber door.With main out of doors
By chamber door surrounding adhesion sealing ring, then chamber door is closed by door lock handle and prevents rainwater moisture from entering.Have to reach more
The waterproof moisture-proof effect of effect, generally arranges an appropriate number of heater and its temperature and humidity control device in mechanism case, and
Casing top and bottom appropriate location are provided with spiracle, so that the inside and outside aerial respiration that completes of casing is exchanged.Have also on casing
Add rain cover.However, fact proved, on the basis of existing structure, although taking many measures, waterproof, moisture proof
（Condensation）The problem of do not solved at all, the problems such as still largely there is mechanism case watered and wetting, corrosion of elements, safeguard
Workload is big.
The content of the invention
