Embodiment 1

[0031] Such as figure 1 Shown: The dust-proof and heat-dissipating device for transformers in the workshop, including a cabinet body 1. There is a space for installing the transformer inside the cabinet body 1. There is a cabinet door 12 on the front side of the cabinet body 1. The top of the cabinet body 1 is fixedly connected with an upper Cover 11, the upper cover 11 is a curved surface with a high middle and low sides, and the horizontal projection of the upper cover 11 covers the horizontal projection of the cabinet body 1. The left and right sides of the cabinet body 1 are provided with heat dissipation windows 2, and the positions of the heat dissipation windows 2 on the cabinet body 1 are fixedly connected with dust-proof nets, which can completely cover the heat dissipation windows 2.

[0032] The inside of the heat dissipation window 2 is provided with a waterproof mechanism, and the outside of the heat dissipation window 2 is provided with a rainwater collection mec...

Embodiment 2

[0045] Compared with the first embodiment, this embodiment differs only in the internal structure of the heat dissipation pipe.

[0046] A flow rate control device is provided at the water outlet position of the heat dissipation pipeline 6,

[0047] Such as Figure 4 As shown: the flow rate control device includes a folded plate 61 located inside the heat dissipation pipe 6 and a cylinder 63 with a piston rod 64, a spring 62 is fixed between the folded plates 61, and the right end of the folded plate 61 is fixedly connected to the heat dissipation pipe 6. The left end of the heat dissipation pipe 6 is fixedly connected with the piston rod 64 of the cylinder 63 , and the cylinder 63 is fixed inside the heat dissipation pipe 6 .

[0048] The working process of this embodiment:

[0049] When the temperature in the cabinet body 1 rises, the gas in the cylinder 63 will be heated and expand, pushing the folding plate 61 to fold, and the area where the folding plate 61 blocks the w...

Abstract

The invention relates to the field of electric equipment, in particular to a dust-proof and heat-dissipating device for a transformer in a workshop, which includes a cabinet for installing a transformer, a cabinet door for a switch cabinet, and an upper cover covering the top of the cabinet. There are heat dissipation windows, and the cabinet body is located on the inner wall of the upper heat dissipation window side, and a waterproof mechanism is provided. The waterproof mechanism includes a reel fixed at the bottom of the cabinet body and a waterproof curtain curled on the reel; the cabinet body is located on the outer wall of the heat dissipation window side. Equipped with a rainwater collection mechanism, the rainwater collection mechanism includes a base located at the bottom of the heat dissipation window and fixedly connected with the cabinet body, a slide rail fixedly installed on the base, and a water tank for collecting rainwater from the upper cover. A supporting piece is fixed between them; a connecting rope is arranged between the water tank and the waterproof curtain, and the connecting rope is fixedly connected with the water tank and the waterproof curtain respectively. The invention can avoid the problem of transformer failure caused by rainwater entering the cabinet through the heat dissipation window.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a dust-proof and heat-dissipating device for workshop transformers. Background technique [0002] With the maturity of my country's electric power technology, various electric power equipment develops rapidly. Transformer is one of the most common electric power equipment, and its operation status directly determines the safety, stability and reliability of power system operation. Transformers can be divided into dry-type transformers and oil-immersed transformers according to cooling methods. There are many mechanical equipment in the production workshop and the operating load is large, so the workshop generally adopts oil-immersed transformers with strong overload capacity. It is easy to generate heat. If the heat is not dissipated in time, the transformer will fail due to excessive temperature. [0003] In order to solve the problem of transformer heat dissipation, the Chine...
