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

Since the dry-type transformer shell of the present invention includes multiple sealing plates, multiple clamps and multiple beams, the adjacent beams are fixedly connected to form a cuboid frame of the dry-type transformer shell, and the clamps are composed of lock blocks, slide bars and slide blocks. The sealing plate is clamped by the side edge of the beam and the end face of the locking block. This structure does not require electric drills, rivet equipment, screwdrivers and other auxiliary tools in the process of assembly and disassembly. Sealing plates, clips, and beams can be recycled after disassembly to save resources; and this structure can only be disassembled inside the new dry-type transformer shell, and the outside cannot be disassembled, which enhances safety performance. the

As an improvement of the dry-type transformer shell of the utility model, the clip and the lock block are rectangular parallelepiped. The cuboid shape is easy to process, and the end surface area is large, which can firmly clamp the sealing plate and increase safety. the

As an improvement of the dry-type transformer shell of the utility model, the sliding rod and the sliding block of the clip are both cylindrical. The cylindrical shape is easy to process, and also reduces the processing difficulty of the chute matched with it. the

As an improvement of the dry-type transformer shell of the utility model, the length of the locking block is larger than the diameter of the sliding block. The sealing plate can be clamped tightly, which is more secure. the

As an improvement of the dry-type transformer shell of the utility model, there are two grooves on each chute; two clips on each chute are respectively matched with the two grooves. The shell of the dry-type transformer will inevitably be impacted by external forces during the handling process. Two grooves are designed to fit the clips respectively, taking into account safety issues. the

Detailed ways:

The dry-type transformer housing of the present invention will be further described below in combination with the accompanying drawings and specific embodiments. the

Please refer to Fig. 1 to Fig. 6, the dry-type transformer housing of the present invention includes a plurality of sealing plates 1, a plurality of clips 2 and a plurality of beams 3, and the adjacent beams 3 are connected by bolts to form a cuboid frame of the dry-type transformer housing. The clip 2 described above is composed of a lock block 2.1, a slide bar 2.2 and a slide block 2.3; each beam 3 is provided with two chutes 4 for the clip 2 to slide, and the chute 4 is composed of a slide bar 2.2 for sliding. The vertical groove 4.2 and the horizontal groove 4.1 for sliding block 2.3 are formed (i.e. T-shaped groove), and described vertical groove 4.2 side beams are provided with groove 5 for sliding block 2.3 entering in the horizontal groove 4.1; The root beams 3 are provided with two side edges 3.1 which respectively block the outer side of a corresponding sealing plate 1, and the lock block 2.1 has an end surface which can reach the inner side of the self-sealing plate 1; the sealing plate 1 passes through the beam 3 The side edge 3.1 is fastened with the end face of the lock block 2.1. the

As preferred in this example: the slide bar 2.2 and slide block 2.3 of the clip 2 are cylindrical, and the slide block 2.3 is a cuboid; the length dimension of the lock block 2.1 is greater than the diameter of the slide block 2.3; the groove 5 There are two on each chute 4 ; there are two clips 2 on each chute 4 to cooperate with the two grooves 5 respectively. the

Clip 2, chute 4 and groove 5 are due to cooperate to complete the clamping action, and all must match.
