Specific embodiment
It is practical below in conjunction with this to enable the purpose of this utility model, feature, advantage more obvious and understandable
Attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that under
The described embodiments are only a part of the embodiments of the utility model in face, and not all embodiment.Based on the utility model
In embodiment, all other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.
It please refers to shown in Fig. 1 to Fig. 5, present embodiments provides a kind of GIS device CT secondary terminal box rain cover, including a left side
Rain cover 10 and right rain cover 11, convenient for tight installation.
Wherein, which is provided with round macropore behind, is pierced by for CT secondary terminal box 21.
Further, 10 top of left rain cover and front edge are equipped with groove 12, and the left rain cover 10 passes through recessed
Slot 12 and right 11 assembly and connection of rain cover, cable punching hole is arranged at the bottom of 11 assembled formation of the left rain cover 10 and right rain cover
13, it is fixed by screw 14 between the left rain cover 10 and right rain cover 11.
CT secondary connection outer sheath tube can be pierced by by the cable punching hole 13, be laid in CT secondary connection outer sheath tube
Secondary cable 23.The design of cable punching hole 13 can be coupled in lower end with CT secondary connection outer sheath tube, on the one hand prevent outer shield
Casing is hurt under stress by rain cover marginal portion；Another aspect rainwater can be flowed vertically along 13 surface of cable punching hole
Under, prevent rainwater by entering rain cover inside cable punching hole 13.Cable punching hole 13 doubles as drainage, if to prevent that rain occurs
When water is entered inside rain cover, facilitate rainwater to exclude, avoid long-term ponding, lead to internal humidity, equipment is got rusty.
Left 10 top of rain cover and front edge are designed using groove 12, are matched with right 11 top of rain cover and front edge
It is combined dress, rainwater can only flow away along right 11 rain cover surface of rain cover, so that rainwater will not enter inside rain cover.Installation
When, left rain cover 10 first can be buckled in CT secondary terminal box 21 from left to right and fixed with hand, right rain cover 11 is past from the right side
Left (position point slightly lower than left rain cover 10 and rear facilitates right rain cover 11 to be inserted into groove 12) compresses left rain cover 10, then
Right rain cover 11 is pushed up into insertion 12 bottom of top groove, then right rain cover 11 is pushed and plugged forward into 12 bottom of front groove,
Two parts rain cover is finally tightened into fixation with screw 14.
Further, the left rain cover 10 and right rain cover 11 offer venthole 15 respectively, on the venthole 15
Add rain-proof cover 16.When internal moist, when temperature increases, moisture can be discharged from two sides venthole 15, prevent it is internal it is moist with
Condensation.It has installed rain-proof cover 16 above venthole 15 additional, can prevent rainwater from flowing backward and enter in rain cover.
Further, the front of the left rain cover 10 and right rain cover 11 is equipped with observation window made of organic glass
17, the observation window 17 is equipped with protective cover 18.Facilitate and daily checks 22 parameter of CT nameplate.
Organic glass observation window 17 has the characteristics that high transparency, high mechanical strength, light-weight.Observation window 17 is equipped with protection
Cover 18.When on the one hand preventing from damaging when organic glass observation window 17 or being bad with the sealing of rain-proof cover body, rainwater enters rain cover
It is internal；On the other hand avoid the long-term direct projection organic glass of sunlight that aging is caused to rupture and intake.
The observation window 17 is in a preset tilt angle.It is designed using tilt angle, outside rainwater can pass through when normal
18 top of protective cover is stayed with inclination, prevents rainwater collecting at 18 top of rain-proof sunshade protective cover.In addition, working as a small amount of rainwater
When into rain-proof sunshade 18 inside of protective cover, rainwater can also be stayed by the bottom that inner inclination designs, and prevent rainwater collection
Gather in 18 interior bottom portion of rain-proof sunshade protective cover.
Further, the front of the protective cover 18 also adds dodge gate 19；
The dodge gate 19 is fixed on 18 top of protective cover by hinge 20, and the bottom of the dodge gate 19 exceeds protective cover
18 bottom.Point slightly longer than 18 bottom of rain-proof sunshade protective cover is designed in 19 bottom of dodge gate, and aspect personnel strike out dodge gate with the hand
19.When normal operation, dodge gate 19 is in off state, and plays the role of rain-proof sunshade.When needing to check CT 22 parameter of nameplate, work
Make personnel and door can be opened check, shutting naturally after checking.
Further, screw 14 and 14 hole of screw are sealed using mesomorphism glue, prevents screw 14 and 14 hole of screw long
Phase rain erosion gets rusty into water.
Left rain cover 10 and right rain cover 11 are made of stainless steel material corrosion-resistant, that toughness is high.Avoid due to it is long when
Between expose to the sun and rain cause to get rusty, aging, deformation.
In conclusion a kind of GIS device CT secondary terminal box rain cover provided in this embodiment, can prevent CT secondary connection
The water inlet of 21 sealing strip of box, aging and terminal box infiltration phenomenon, extend the service life of equipment, reduce equipment fault and interruption maintenance
Risk, improve level of security.The venthole 15 of rain cover designs, and can avoid preventing moist and condensation inside rain cover, causes
Secondary terminal box 21, which gets rusty to insulate with internal unit, to be reduced.It is convenient that rain cover installs additional, scientific and reasonable, effectively extends maintenance week
Phase reduces maintenance cost, under the premise of guaranteeing safety in production, improves effectiveness of operation.
