Description
Technical field
It the utility model is related to switchgear technical field, more particularly to a kind of Novel armored type withdraw-type is AC metal closed
Switchgear.
Background technology
The indoor complete distribution of ZKYN28-12 armored type withdraw-type ac metal closing switch gears system three-phase alternating current 50Hz
Device, for receiving and distributing the network power of 3.6~12kV and carry out circuit control protection and monitoring.In the past 10 years
ZKYN28-12 switchgears are constantly subjected to the favor of numerous users, are the mainstream cabinet types in high pressure complete set of equipments.As power plant,
Substation and industrial and mining enterprises receive and the three-phase electric energy of distribution 50Hz, 35kV power grid is used, and control, protection and inspection are played to circuit
The functions such as survey, can be also used for the place of frequent operation, possess perfect " five is anti-" function.Traditional ZKYN28-12 switchgears
With following defect：First, security deficiency：In breaking circuit breaker, complete, such as need manual for electronic separating brake under normal circumstances
Breaking circuit breaker, then be switched on cabinet door progress.Because abnormal use condition or maloperation cause internal short circuit fault to cause
During striking, if opening door operation, it would be possible to the person is caused greatly to injure.Therefore switchgear, which possesses, forces door-closing operation just
It is extremely important.At present, major part ZKYN28-12 switchgears on the market are not to force door-closing operation, i.e. breaker chamber
Door can operating breaker in the case where opening, closing；2nd, decompression cover is easy to fall off：Switchgear decompression cover is routinely each three
Metal bolts and three nylon bolts are fixedly mounted；3rd, structure is not sufficiently stable, maintenance inconvenience.
Utility model content
The purpose of this utility model is AC metal closed in order to solve ZKYN28-12 armored types withdraw-type in the prior art
The problem of switchgear security deficiency, decompression cover is easy to fall off, and structure is not sufficiently stable, maintenance inconvenience, and what is proposed is used for one kind
Novel armored type withdraw-type ac metal closing switch gear.
To achieve these goals, the utility model employs following technical solution：
