Description

A storm door for substations in coastal cities

technical field

The utility model relates to the field of doors and windows, in particular to a windproof door of a substation in a coastal city.

Background technique

At present, Guangdong Province, which is located in the tropical and subtropical monsoon climate zone, is often hit by typhoons from June to October, and the power of typhoons has always shown a strong trend over the years. In recent years, the typhoon's rapid wind and strong destructive power have caused disproportionate impacts on more than 500 substations in 13 cities along the coast of Guangdong.

For traditional open substations, since the equipment is directly exposed to the outdoor environment, when a typhoon comes, the equipment in the substation without building protection barriers will directly face the invasion of wind and rain, and are prone to failure in severe weather conditions. Among these potential failures, in addition to the siltation of drains and leakage of buildings, which are common in typhoon days, the damage to operating equipment caused by blown iron sheets is more direct and violent. In the process of iron sheet hidden danger investigation for wind and flood prevention, the staff tend to ignore the problem of the overall closed structure gate adopted by the substation.

At present, the façade of the door commonly used in open substations is a whole stainless steel plate, and its frame support structure is mainly stainless steel columns around it. The following problems exist in the actual use of coastal typhoon areas:

First, when a strong typhoon hits, the frame support structure is mainly stainless steel columns around the gate, due to the uneven force, it is easy to twist and deform in the weak bearing area in the middle, which further causes the gate to loosen, even if the gate is still on the track On the other hand, the gate after the deformation of the facade is difficult to put into normal use again;

Second, when a strong typhoon hits, the entire stainless steel façade with a large area and no holes will directly bear the power of the typhoon. When the wind is strong enough, the unbearable gate will loosen and even fall off the track, or even be blown Going to outdoor equipment threatens the safe operation of the power grid.
