The purpose of the utility model is to overcome the deficiency of the prior art, there is provided a kind of suitable for the exhausted of GG1A switchgears
Edge protective plate, improves the insulating protection level and job security of GG1A switchgears, and helps to reduce power off time, brings
Economic benefit.
Technical solution is used by the utility model solves its technical problem：
A kind of insulating protective plate suitable for GG1A switchgears, the GG1A switchgears top, which is equipped with, is exposed to outer main mother
Line and bus isolating switch, including insulating protective plate and U-shaped mounting portion；The U-shaped mounting portion is arranged at the insulating protective plate
Bottom, and Matching installation is in the top of the GG1A switchgears rear frame；The insulating protective plate is secured to the U-shaped peace
The top in dress portion, and the main bus-bar to the GG1A switchgears and bus isolating switch formation insulation masking.
As a preferred embodiment, the insulating protective plate includes two insulation support plates, this two insulation support plates are angled
Be fixed together mutually, form a dog-ear shape, the dog-ear shape be inclined to the rear sides of the GG1A switchgears with ensure safety away from
From.
As a preferred embodiment, the U-shaped mounting portion totally two, which is arranged on the insulating protective plate
Two side of left and right of bottom.
As a preferred embodiment, the insulating protective plate is rotationally pivotally mounted in the U-shaped mounting portion, and can cover
Switch between state and inspecting state.When the insulating protective plate is located at shielding status, insulating protective plate is shielded in switchgear
Back side top, main bus-bar and bus isolating switch to switch cabinet top portion form insulation masking；The insulating protective plate is positioned at inspection
When repairing state, the insulating protective plate is dug to switchgear side, and operation maintenance personnel can be to the main bus-bar and busbar in switch cabinet top portion
Disconnecting switch carries out repair and maintenance.
As a preferred embodiment, the pivoting point of the insulating protective plate and the U-shaped mounting portion has two rotary spacings, should
Two rotary spacings of insulating protective plate correspond to the shielding status and inspecting state respectively.
As a preferred embodiment, the insulating protective plate uses high resistance high-molecular organic material.
The beneficial effects of the utility model are：
1. improve dielectric level；Large area is used according to due to a kind of protection plate part of GG1A switchgears protective plate
Isolation material, can greatly improve apparatus insulated level.
2. improve job security；After a kind of GG1A switchgears protective plate, during daily tour, avoid with
The risk of charging equipment exposed part distance deficiency.
3. the injury for preventing top apparatus explosion, fracture belt from coming；Because have a kind of protection of GG1A switchgears protective plate with
Buffer action, when there is a situation where supporting porcelain insulator breaking, explosion at the top of GG1A switchgears, the personnel that avoiding to bring are pounded
Injure the risk of electric shock.
4. economic benefit.When without this protective plate, personnel should meet as defined in safety enough with powered position exposed part
Safe distance, if operating distance, not less than requiring, charging equipment should have a power failure.Due to a kind of GG1A switchgears protective plate
The protection played and buffer action, provide according to safety, when 10kV, below 35kV have insulating barrier, human body and instrument with it is powered
The distance between position can be less than the safe distance in the case of non-inductive windings.Therefore, using a kind of GG1A switchgears protective plate,
Help to reduce unnecessary power failure work, reduce corresponding power economy loss.
5. it is flexible and convenient to use, the conventional maintenance maintenance of switchgear is not influenced.Insulating protective plate can be in state of insulation and inspection
Repair and switch between state.Main bus-bar that can be to switch cabinet top portion by the way that insulating protective plate is dug after switchgear power-off and mother
Line disconnecting switch carries out Maintenance and Repair.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But one kind of the utility model is fitted
Insulating protective plate for GG1A switchgears is not limited to embodiment.
