Background technology:

Dry-type transformer case is the significant components in the dry-type transformer system, and the excellent protection that provides of dry-type transformer is provided for it, guarantees the normal operation of dry-type transformer.The shrouding and the framework of the dry-type transformer case of industry use at present adopt fixed structures such as rivet, self-tapping screw more.Technologies such as it needs to hole in installation process, tapping, reaming, spot-facing, tighten the screws, installation and processing technology are complicated, and operating efficiency is lower.And the fixed structure outside of self-tapping screw is removable, does not reach purpose of safety.It needs aids such as electric drill, rivet equipment, screwdriver in assembling and dissembling process, damage shrouding and framework easily, can not recycle, and causes unnecessary waste.

The utility model content:

The problem that the utility model dry-type transformer case will solve is, overcomes above existing technological deficiency, and a kind of dry-type transformer case simple, safe, that can recycle of installing and removing is provided.

The technical solution of the utility model dry-type transformer case is, a kind of dry-type transformer case with following structure is provided, comprise polylith shrouding, a plurality of clamp and many beams, the be composed of a fixed connection cuboid framework of dry-type transformer case of adjacent beam, described clamp is made up of lock dog, slide bar and slide block; Be provided with two chutes for the clamp slip on the every beam, described chute is formed by the vertical slots that supplies slide bar to slide with for the level trough that slide block slides, and described vertical slots two curb girders are provided with and supply slide block to enter the interior groove of level trough; Be provided with two side edges of blocking a corresponding shrouding lateral surface respectively on the every beam, the end face that can support from the shrouding medial surface is arranged on the described lock dog; Described shrouding tightens along the end face with lock dog by the side of beam.

After adopting said structure, the utility model compared with prior art has the following advantages:

Because the utility model dry-type transformer case comprises polylith shrouding, a plurality of clamp and many beams, the be composed of a fixed connection cuboid framework of dry-type transformer case of adjacent beam, described clamp is made up of lock dog, slide bar and slide block, and described shrouding tightens along the end face with lock dog by the side of beam.This structure does not all need aids such as electric drill, rivet equipment, screwdriver in assembling and dissembling process, its installation and processing technology simple and fast, dismantle also very convenient, not fragile shrouding and framework.Shrouding, clamp, beam can be recycled after dismounting, economize on resources; And this structure only could be dismantled in novel dry-type transformer case, and is outside non-disconnectable, and security performance strengthens.

The described lock dog of the described clamp of a kind of improvement as the utility model dry-type transformer case is a cuboid.Rectangular shape is easy to processing, and face area is bigger, can firmly tighten shrouding, increases fail safe.

A kind of slide bar, slide block that improves described clamp as the utility model dry-type transformer case is cylindrical.Cylindrical shape is easy to processing, also reduces the difficulty of processing of the chute that is mated.

A kind of diameter that improves the length dimension of described lock dog greater than slide block as the utility model dry-type transformer case.Can tighten shrouding, safer.

The described groove of a kind of improvement as the utility model dry-type transformer case all has two on each chute; Described clamp on each chute, all have two respectively with two groove fit.Dry-type transformer case can be subjected to external impacts unavoidably in handling process, design two grooves and cooperate respectively at clamp, considers safety problem especially.

Embodiment:

Below in conjunction with drawings and the specific embodiments the utility model dry-type transformer case is described further.

See also Fig. 1 to Fig. 6, the utility model dry-type transformer case comprises polylith shrouding 1, a plurality of clamp 2 and many beams 3, adjacent beam 3 connects to form the cuboid framework of dry-type transformer case by bolt, and described clamp 2 is made up of lock dog 2.1, slide bar 2.2 and slide block 2.3; Be provided with two chutes 4 on the every beam 3 for clamp 2 slips, described chute 4 is formed (being T-slot) by the vertical slots 4.2 of sliding for slide bar 2.2 with for the level trough 4.1 that slide block 2.3 slides, and 4.2 liang of curb girders of described vertical slots are provided with for slide block 2.3 and enter the interior groove 5 of level trough 4.1; Be provided with two sides of blocking corresponding shrouding 1 lateral surface respectively on the every beam 3 along 3.1, the end face that can support from shrouding 1 medial surface is arranged on the described lock dog 2.1; The side of described shrouding 1 by beam 3 along 3.1 with the end face chucking of lock dog 2.1.

As preferred in this example: slide bar 2.2, the slide block 2.3 of described clamp 2 are cylindrical, and slide block 2.3 is a cuboid; The length dimension of described lock dog 2.1 is greater than the diameter of slide block 2.3; Described groove 5 all has two on each chute 4; Described clamp 2 all has two to cooperate with two grooves 5 respectively on each chute 4.

Clamp 2, chute 4 and groove 5 are finished the chucking action because of cooperating, various must the coupling.According to general knowledge as can be known: described slide block 2.3 diameters are slightly less than the width of level trough 4.1, and greater than the diameter of slide bar 2.2, described slide block 2.3 highly is slightly smaller than the degree of depth of level trough 4.1; The diameter of described slide bar 2.2 is slightly less than the width of vertical slots 4.2; The height sum of slide bar 2.2 and slide block 2.3 is a bit larger tham vertical slots 4.2 and level trough 4.1 degree of depth sums.The width of described level trough 4.1 is greater than the width of vertical slots 4.2.

Installation process is: at first, shrouding 1 is installed, the side of shrouding 1 and beam is fitted along 2.1; Secondly, rotate clamp 2, when the end face 1 (or end face 2 2.5) that makes lock dog 2.1 and shrouding 1 are vertical clamp 2 insertion grooves 5 until level trough 4.2 bottom surfaces; The 3rd, clamp 2 advances half-twist behind the certain distance in chute 4, utilizes the lock dog of clamp 2 fixing shrouding 1 and beam 3 chuckings.Install remaining shrouding 1 successively, finally form dry-type transformer case.

During dismounting, only need rotation clamp 2 nine ten degree, when the end face 1 (or end face 2 2.5) that makes lock dog 2.1 and shrouding 1 are parallel with clamp 2 release chutes 4 to groove 5 places, take out clamp 2, take away shrouding 1, and looser a bolt, just realized the dismounting of dry-type transformer case with the method.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all belong in the protection range of technical solutions of the utility model according to the utility model technical spirit.
