Abstract

The utility model discloses a novel outdoor casing ventilating structure, which is characterized in that ventilating openings [5] are arranged on each lateral surface of a protective steel plate casing [4], and the novel outdoor casing ventilating structure is provided with a rain-shielding hood [1], a U-shaped elastic nut [2] is clamped in a round hole on the inner edge of the rain-shielding hood [1], a sealing joint strip [3] is arranged on the inner edge, the rain-shielding hood is fixed on the ventilating openings [5] on the casing panel through a bolt, and a protective netting [6] is arranged in the rain-shielding hood. The utility model has the advantages of simple structure, convenient processing, low manufacture cost, excellent application and polarization prospect, which needs not complex punching equipment, can totally satisfy the protective and ventilation requirements when equipment are used outside under bad condition, and guarantees the safe, reliable and normal run of equipment in the casing.

Description

A kind of novel outdoor ventilation for enclosures structure

Technical field

The utility model relates to a kind of aeration structure, is specifically related to the aeration structure of a kind of dry-type transformer or the employed outdoor shell of other equipment.

Background technology

For electric equipments such as dry-type transformers,, must there be the rainproof shell of good ventilation condition to protect if it is used the open air.Common outdoor type outer cover of steel plate generally adopts the aeration structure of venetian blind type, have following deficiency: 1) size in each louvre ventilation hole is approximately " 12*50mm ", for reaching the draught area of regulation, need on outer cover of steel plate, open number row venetian blind type ventilation hole, the utilance of draught area is generally 50%, even the overall dimension of needs increase shell, needing special punching apparatus, difficulty of processing is higher; 2) out of doors under the situation of condition very severe (weather of violent storm) can not play good protective action to equipment, can not prevent that well rainwater from splashing in, can not prevent that maybe less mosquito from flying into two and influencing equipment.

Summary of the invention

The purpose of this utility model is to provide a kind of novel outdoor ventilation for enclosures structure at the deficiencies in the prior art, this aeration structure can reach IP13 or higher degree of protection, and electric equipments such as assurance transformer are the purpose of safety, reliable normal operation in the enclosure.

The technical scheme that the utility model adopted is: on the shoulder guard shell of equipment, according to actual draught area needs, offer ventilating opening on each side; Be provided with the guard shield that keeps off the rain of " L " shape, card is gone up the U-shaped elastic nut in the circular hole at edge within it, and sealing joint strip is set on the inside edge; With the guard shield that keeps off the rain of " L " shape by bolt outside housing face-plate is opened the air port, sealing joint strip can prevent that rainwater from infiltrating, and in the protective cover that keeps off the rain protection network is set, and prevents that less mosquito from flying into and influence the transformer normal operation from ventilation hole.

In order to prevent to dabble, influence the transformer normal operation, in the guard shield that keeps off the rain, except that protection network is set, anti-splash board is set again, preventing less mosquito when ventilation hole flies into, prevent to dabble and influence the transformer normal operation.

According to key points in design of the present utility model, described protection network also can be arranged on the ventilating opening of shell.

The utility model is simple in structure, easy to process, do not need complicated punching apparatus, low cost of manufacture, and the protective ventilation demand can satisfy equipment fully and use under the situation of inclement condition out of doors the time, assurance equipment is safety, reliable normal operation in the enclosure, has the good application and promotion prospect of frame.

Embodiment

In structure shown in Figure 1, on the shoulder guard shell 4 of equipment,, on each side, offer ventilating opening 5 according to actual draught area needs; Be provided with the guard shield 1 that keeps off the rain of " L " shape, card is gone up U-shaped elastic nut 2 in the circular hole at edge within it, sealing joint strip 3 is set on the inside edge, the guard shield 1 that keeps off the rain connects firmly housing face-plate by bolt and opens outside the air port 5, sealing joint strip can prevent that rainwater from infiltrating, protection network 6 is set in the protective cover that keeps off the rain, prevents that less mosquito from flying into from ventilation hole and influence the transformer normal operation.

In structure shown in Figure 2,, in the guard shield 1 that keeps off the rain, except that protection network 6 is set, anti-splash board 7 is set again in order to prevent to dabble.

In structure shown in Figure 3, according to key points in design of the present utility model, described protection network 6 also can be arranged on the ventilating opening 5 of shell.

Claims
