Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Such as each accompanying drawing, high voltage power distributing cabinet water-proof top cover device, including high-voltage board water-proof top cover assembly 1 and high-voltage board cabinet 2,
The high-voltage board water-proof top cover assembly 1 reserves spacing by support member and the upper surface of high-voltage board cabinet 2, is arranged on high-voltage board cabinet
2 tops.The support member includes Left-side support plate 6, Right side support plate 7, front apron 4 and rear baffle 5, the Left-side support plate 6,
Front apron 4, Right side support plate 7 and rear baffle 5 are fixed on the lower surface of high-voltage board water-proof top cover assembly 1 from beginning to end respectively.Wherein, it is described
Front apron 4 and rear baffle 5 are made up of thin plate, offer grid hole thereon.
The front apron 4 supports the height on direction to support the height on direction, the Left-side support plate higher than rear baffle 5
6 and Right side support plate 7 support direction height its tend to diminish from the direction of front apron 4 to the direction of rear baffle 5 along its length.Institute
Stating high-voltage board water-proof top cover assembly 1 includes high-voltage board waterproof top top cover 3, the left and right side point of the high-voltage board waterproof top top cover 3
It She You not drop down on the left of top cover on the right side of tank 3-1 and top cover and drop down tank 3-2, drop down on the right side of tank 3-1 and top cover and drops down on the left of the top cover
It is respectively equipped with the outside of tank 3-2 on the left of the upper seam 3-3 of splicing and splicing lower seam 3-4, or the top cover and drops down tank 3-1 and top
Lid right side, which is dropped down on the outside of tank 3-2, is respectively equipped with the lower seam 3-4 of splicing and the upper seam 3-3 of splicing, in the splicing seam 3-3 with
The lower seam 3-4 of splicing is mutually linked, and the space closed completely is formed when coordinating each set splicing of power distribution cabinet.The high-voltage board waterproof
Exceed power distribution cabinet back door 16 in the horizontal direction of top cover 3 of top.
The upper surface of the high-voltage board cabinet 2 is provided with cable vault's explosion-proof relief plate 9, the and of main bus-bar room explosion-proof relief plate 10
Breaker chamber explosion-proof relief plate 11, cable vault's explosion-proof relief plate 9, main bus-bar room explosion-proof relief plate 10 and breaker chamber are explosion-proof
Fixed between pressure relief plate 11 and corresponding cell by plastic screw.Small mother is also set up in the upper surface of the high-voltage board cabinet 2
Line passage 13, small bus room cover plate 12 is covered with the small busbar channel 13.
Specific structural principle：Respectively there are a supporting plate, respectively Left-side support plate in the side of high-voltage board waterproof top top cover 3 or so
6 and Right side support plate 7, for supporting high-voltage board waterproof top top cover 3, supporting plate has certain altitude, to high-voltage board waterproof top top cover 3
Certain space is left between the upper surface of high-voltage board cabinet 2, for the motion space of each explosion-proof relief plate under top plate,
I.e. cable vault's explosion-proof relief plate 9, main bus-bar room explosion-proof relief plate 10, breaker chamber explosion-proof relief plate 11 are in each small indoor generation
Pressure release during arcing, prevent the expansion of accident.Fixed between explosion-proof relief plate and corresponding cell by plastic screw, its screw
A certain amount of load can be born, ensures that explosion-proof relief plate comes off in portion under normal circumstances；When the generation of chamber arcing is powerful
During thrust, its plastic screw will be broken automatically, explosion-proof relief plate side plastic screw is come off, and form pressure release passage, removal
Internal arcing pressure, ensure the safety of other equipment.It is high when arcing in cabinet by drawing off, and reaches in high-voltage board waterproof top top cover 3
There are two pieces of baffle plates the front and rear sides of pressure cabinet waterproof top top cover 3, and respectively compared with front apron 4 and rear baffle 5, grid hole is provided with baffle plate,
Gas pressure caused by arcing can be drawn off forwards, backwards, meanwhile, front apron 4 is made up with rear baffle 5 of thin plate, has prevented foreign matter
Getting in, fixing point is that the top of high-voltage board waterproof top top cover 3 is fixed, and bottom does not set fixing point, when pressure reaches to a certain degree,
When grid hole has little time to draw off big pressure on baffle plate, front apron 4 will be open with rear baffle 5, form larger pressure release passage,
Ensure that internal arcing produces pressed gas and discharged in time.
To realize above-mentioned function, the present invention by the high-voltage board waterproof top top cover 3 on high-voltage board water-proof top cover assembly 1 above
The left and right sides, which has to drop down on the left of top cover on the right side of tank 3-1 and top cover respectively, drops down tank 3-2, when there is current to drop down at the top of power distribution cabinet,
Water, which passes to, to be dropped down in tank.It is low after height before top cover support part Left-side support plate 6 and Right side support plate 7, just make high-voltage board waterproof
The water dropped down in the top cover 3 of top in tank trickles backward, and dropping down the mouth of a river by the left and right sides on rear baffle 5 flows out.Push up on high-voltage board waterproof top
Lid 3 exceeds power distribution cabinet back door 16, water droplet is directly dripped to ground.The left and right sides of high-voltage board waterproof top top cover 3 has in splicing respectively
The seam 3-3 or lower seam 3-4 of splicing, each set of power distribution cabinet form the space closed completely when splicing, will not produced in splicing part
The situation of raw leak.Because power distribution cabinet and cabinet easily form error, produce and spell cabinet gap, the spelling cabinet of high-voltage board waterproof top top cover 3
It is designed with regulating error, seam 3-3, which is caught in, in splicing drops down tank (dropped down on the left of top cover on the right side of tank 3-1 or top cover and drop down tank 3-2)
There are several millimeters of regulation leeway centre, left and right, splice lower seam 3-4 and are caught in the upper seam 3-3 of splicing curved mouth, also there is several millimeters
Leeway is adjusted, this ensures that the complete splicing between seam, does not have the generation of drainage.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
