Abstract
The utility model provides an insulating sheath specially designed for a high-tension switch tank body. The insulating sheath is provided with two cross pipe-shaped half casings (1 and 2), and thermal insulation layers (3 and 4) and a flexible heating plate layer (5) are sequentially adhered to the inner walls of the two cross pipe-shaped half casings. The insulating sheath comprises the two butted half casings which are designed according to the shape of the high-tension switch tank body and can wrap the high-tension switch tank body; in installation, the two half casings wrap the high-tension switch tank body and are in fastening connection through bolts, and a sealing structure is further arranged on the insulating sheath for full-enclosed wrapping, so as to realize favorable thermal insulation effect and rainproof effect; and if the external temperature is over low, a heating plate can be started to heat the tank body to lead the tank body to reach a needed temperature. Therefore, the utility model has the advantages of good thermal insulation effect, convenience in installation, aesthetic appearance, and rainproof property.
Description
Technical field
The utility model relates to a kind of muff, and specifically, it is a kind of high-voltage switch gear tank body special-purpose thermal insulation cover.
Background technology
High-voltage switch gear is the key equipment of power transmission and transformation system, and how in outdoor application, operational environment is extremely abominable, and especially at north cold area, extreme low temperature can reach below-40 ℃.The high-voltage switch gear tank interior requires to have higher insulation property, and it adopts sulphur hexafluoride (SF6) gas as insulating gas at present.When the tank body temperature dropped to below-40 ℃, this gas will produce liquefaction phenomenon, and the product insulation property are reduced, and easily caused bigger security incident.For this reason, need to give the high-voltage switch gear tank body that muff is set, at present, the muff of high-voltage switch gear tank body is all lack of standardization, and the most common is to carry out craft bag bundle with the rubber pange plate, this muff one be wrap up not tight, heat insulation effect is poor, the 2nd, be not with heating, cold especially-40 ℃ of areas still are difficult to reach the insulation requirement in the north, and it also has, and profile is not attractive in appearance, on-the-spot to be difficult for installing, can't effectively to protect shortcoming such as rainwater.
The utility model content
The utility model purpose is in order to overcome the shortcoming of prior art, a kind of high-voltage switch gear tank body special-purpose thermal insulation cover to be provided, and to reach good heat insulation effect, makes it have easy for installation, good looking appearance and rainproof characteristics simultaneously again.
Be real above-mentioned purpose, the technical solution of the utility model is as follows:
It has two cross tubulose half housings, is stained with insulation layer and flexible heating flaggy on the inwall of these two cross tubulose half housings successively; Be provided with bolt and buckle on described two cross tubuloses, half housing transverse tube abutment joint, half housing vertical tube abutment joint place is provided with extension to edge fit at described two cross tubuloses, and is provided with screw hole on extension butt joint limit.
The further improved technical scheme of the utility model is as follows:
Half housing transverse tube abutment joint place is provided with first hermetically-sealed construction at described two cross tubuloses, and this first hermetically-sealed construction constitutes interior flanging on the edge fit and T shape sealing strip by being located at described two cross tubuloses, half housing transverse tube; Half housing vertical tube abutment joint place is provided with second hermetically-sealed construction at described two cross tubuloses, and this second hermetically-sealed construction is made of the sealing strip that is clipped in the described two and half housing vertical tube extension limits; Be provided with the 3rd hermetically-sealed construction between the pipe end of described two cross tubulose half housings and high-voltage switch gear tank body, the 3rd hermetically-sealed construction is by the interior ring limit that is welded on pipe end and be inlaid in that U-shaped sealing ring on ring limit constitutes in this.
Described insulation layer is made of one deck rubber pange warming plate and an alumina silicate sheathing paper.
The utility model according to the shape fabricating of high-voltage switch gear tank body can be to half housing of two butt joints of tank body inclusion, and heat preserving and insulating material layer and heating plate be set on half inner walls, during installation, two and half housings are wrapped on the high-voltage switch gear tank body, and link together with screw, on this muff, also be provided with hermetically-sealed construction, carry out hermetically sealed parcel, make it reach good heat insulation effect, and rainproof; If ambient temperature is low excessively, can also enable heating plate tank body is heated, reach required temperature.Therefore, this muff has high insulating effect, easy for installation, good looking appearance and rainproof characteristics.

Embodiment
Referring to Fig. 1～3, it has two cross tubuloses, half housing 1,2, this two and half housing can form inclusion to the high-voltage switch gear tank body of cross tubulose, be stained with insulation layer and flexible heating flaggy 5 on the inwall of these two cross tubulose half housings successively, this routine insulation layer adopts one deck rubber pange warming plate 3 and one deck alumina silicate sheathing paper 4.On described two cross tubuloses, half housing transverse tube abutment joint, be provided with bolt and buckle 8, by bolt buckle 8 fastening, the transverse tube of two and half housings is partly fastened be bound up; On described two cross tubuloses, half housing vertical tube abutment joint, be provided with extension, and on extension butt joint limit, be provided with screw hole 9 edge fit 1-2,2-2; Fastening by the screw in the screw hole 9 can make the vertical tube of two and half housings partly be bound up.
Referring to Fig. 1～5, for guaranteeing to overlap interior temperature and effectively rainproof, half housing transverse tube abutment joint place is provided with first hermetically-sealed construction at described two cross tubuloses, and this first hermetically-sealed construction constitutes interior flanging 1-1,2-1 on the edge fit and T shape sealing strip 6 by being located at described two cross tubuloses, half housing transverse tube; Half housing vertical tube abutment joint place is provided with second hermetically-sealed construction at described two cross tubuloses, and this second hermetically-sealed construction is made of the sealing strip 7 that is clipped in described two and half housing vertical tube extension limit 1-2, the 2-2; Be provided with the 3rd hermetically-sealed construction between the pipe end of described two cross tubulose half housings and high-voltage switch gear tank body 13, the 3rd hermetically-sealed construction is by being welded on the interior ring limit 10 on the pipe end and being inlaid in that U-shaped sealing ring 11 on ring limit constitutes in this.
Referring to Fig. 5, after this muff 12 was installed on the high-voltage switch gear tank body 13, muff formed hermetically sealed parcel to high-voltage switch gear tank body 13, plays good insulation effect and rainproof effect.If ambient temperature is low excessively, can open heating plate, the heating by heating plate reaches required temperature.
