Method for using sealing strips for conducting sealing in box-type substation of wind power plant

Abstract

The invention relates to a method for using sealing strips for conducting sealing in a box-type substation of a wind power plant, and belongs to the technical field of substations. According to the technical scheme, door frame steel plates of an outer door of the box-type substation are folded into door frames (5) with rectangular sections, one edge, facing a door leaf (6), of each rectangular section is provided with a gap (7), a fixing end of each magnetic sealing strip is guided into the corresponding gap from one end of the corresponding gap, and each magnetic sealing strip is arranged on the corresponding door frame of the outer door of the box-type substation; the plane of each magnetic surface faces the door leaf, a sealing body of each magnetic sealing strip is bent in the direction of the corresponding fixing end and makes close contact with the inner side of the rectangle of the edgefold of the corresponding door frame so as to serve as a first layer of sealing protection between each door frame and the door leaf, and a second layer of sealing protection is formed between the door leaf and the magnetic surfaces. According to the method, the magnetic sealing strips are convenient to install and not prone to falling off, and the double-layer sealing structure guarantees sealing performance of the outer door of the box-type substation, prolongs service life of electric equipment, and improves operation safety and stability of the box-type substation.

Description

technical field [0001] The invention relates to a method for sealing with a magnetic sealing strip in a box-type substation of a wind farm, especially suitable for box-type substations operating in harsh environments such as high altitude, heavy wind and sand, heavy salt spray, and low temperature, and belongs to the technology of substations field. Background technique [0002] With the rapid development of the wind power industry, more and more box-type substations are operating on the site of wind power generation. The operating environment is harsh, and natural conditions such as wind and sand, rain and snow, moisture, salt spray, and large temperature differences will affect the safety of box-type substations. The operation has a great impact, so the sealing requirements for the enclosure of the box-type substation are very high. The outer door of the box-type substation is often opened and closed during use. If the sealing strip is loose and falls off or the door is s...

AI Technical Summary

Problems solved by technology

The outer door of the box-type substation is often opened and closed during use. If the sealing strip is loose and falls off or the door is slightly deformed, the door will not close tightly; and because the capacity of the box-type substation in a wind farm is generally not less than 1600kVA, the transformer is relatively large. In order to observe , Easy maintenance, the outer door of the box-type substation is usually made larger, and it is easier to close the outlet line tightly

If the outer door is not closed tightly, sand, dust, rain, snow, etc. will be blown into the interior of the shell, affecting the normal operation and service life of electrical components, and what is more, it will cause electrical short circuit and cause safety accidents

The sealing strip of the background art has small deformation and poor elasticity, which is more obvious when the temperature is very low. It is common that the outer door is not easy to close, and the locking rod is difficult to reach the proper position; or after the outer door is closed, the sealing strip cannot fully contact the door leaf. Internal contact, poor sealing, etc.
