Problems solved by technology

It is also unable to meet the requirements in hoisting operations
[0006] The invention with the notification number CN209149902U discloses a dustproof cover for a transformer, which also belongs to the aforementioned structure. The PVC film and thin magnetic strips used in it are extremely restrictive in dustproofing, and the force and strength cannot be used in hoisting. The most important thing is that the dust-proof effect is not ideal, and it is impossible to retrieve the lifting point, let alone meet the high requirements such as the cleanliness of the site environment, wind force, and oxygen content inside the body.

Embodiment 1

[0025] Such as figure 1 , a mobile dust cover for a transformer hanging core, including four angle steel frames 3, the frames 3 are connected and fixed by bolts to form a square frame, dust-proof windows 1 and glass windows 2 are arranged on each side of the frame, and can be used Movable clamping mode, so that the form can slide, the dustproof window 1 is located in the middle, the glass window 2 is located on both sides, the middle part of the angle steel frame 3 is provided with a cross column 4, which is used for supporting and limiting; the lower part of the angle steel frame 3 is The dustproof non-woven fabric 5 is set, thereby forming a cloth cover structure at the lower part of the dustproof cover. Preferably, two dust-proof windows and two glass windows are provided for dust-proof and observation of internal conditions. In order to adapt to different transformers, the size of the formed dust cover is preferably 6000mm in length, 3300 mm in width and 650 mm in height,...

Embodiment 2

[0029] This embodiment provides a structure of a dust-proof window on a dust-proof cover. The dust-proof part of the dust-proof window has three layers, including an activated carbon layer, a filter paper layer and a non-woven fabric layer. During production, the filter paper is used to wrap the activated carbon , the surroundings are glued to form a filter, and the outside of the filter is wrapped with non-woven fabric, and then fixed with the window frame. The size can be specifically set according to the size of the specific window opening. Preferably, activated carbon is particles that can adsorb PM3, so as to achieve the technical effects of dust prevention and ventilation.

Abstract

The invention discloses a transformer dust cover for hoisting operation. The dustproof cover comprises four angle steel frames, wherein the frames are connected and fixed through bolts to form a square frame, dustproof windows and glass windows are arranged on all faces of the periphery of the frame, transverse columns are arranged in the middles of the angle steel frames, and dustproof non-wovenfabric is arranged on lower portions of the angle steel frames. The dustproof cover is advantaged in that the dustproof cover is simple in structure, easy to manufacture and connect and convenient touse, the dustproof windows and the glass windows can play a role in dust prevention and observation, a non-woven fabric cover structure is adopted at the joint of the transformer and the dustproof windows, and dust isolation can be effectively guaranteed. The dustproof cover is advantaged in that the movable windows and the windows are adopted, the windows can be opened according to a hoisting point, hoisting is facilitated, and the high requirement for the field environment is met.

Description

technical field [0001] The invention relates to the technical field of transformer hoisting, in particular to a movable dustproof cover for a transformer hanging core. Background technique [0002] The substation is the link connecting the power grid, and the transformer is the core equipment of the substation, especially the main transformer, which is the core of the core and directly affects the efficiency and effect of the substation. The transformer hanging core work is an important item for transformer inspection. The main transformer hanging core work has extremely high environmental requirements during installation, and the site environment cleanliness, air humidity, ambient temperature, wind force, and oxygen content inside the body need to be met. Therefore, dust-proof measures should be taken on the upper part of the transformer when lifting the core to ensure that no dust and other debris enter the transformer body, improve the installation quality of the transfor...
