Abstract
The utility model relates to the cabinet body of a high-tension metal closed looped-network switch cabinet, which comprises a cabinet body. The upper end of the cabinet body is provided with a vent hole communicated with the air inside the cabinet body. The upper end of the cabinet body is fixedly provided with an exhaust fan and the vent hole is covered by the exhaust fan. According to the technical scheme of the utility model, the heat radiation of the cabinet body of the switch cabinet is performed timely, so that the accelerated aging phenomenon of electrical elements is avoided. Therefore, the normal service lives of electrical elements are ensured.
Description
Technical field
The utility model relates to a kind of power supplying and distributing equipment that is applied to electric power system, is specifically related to a kind of high-pressure metal sealing looped network switch cabinet body.
Background technology
Ring main unit has played the function of branch, segmentation and contact in distribution system, therefore be used widely in the cable net transformation of ground, city.Ring main unit is a kind of miniaturization, switchgear cheaply, is applicable to the power supply of ring network power supply and terminal, and the distribution system as city ring network power supply, industrial and mining enterprises, skyscraper, residential quarters etc. also is applicable to the integral and intelligent transformer station of packing into.At present, in the production industry of ring main unit, be the space of a relative closure in the ring main unit, electric elements are when internal operation, can send a large amount of heats, the cooling air can only rely on the gap on the cabinet to enter in the cabinet, because the gap is little, can't flow very soon again in cabinet, after entering, air also becomes hot gas, if untimely discharge is then accelerated electric elements easily and worn out, cause shorten the useful life of electric elements.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model is to provide a kind of high-pressure metal sealing looped network switch cabinet body that can in time dispel the heat, and to avoid the accelerated ageing of electric elements, guarantees the normal useful life of electric elements.
The technical scheme that realizes the utility model purpose is as follows:
High-pressure metal sealing looped network switch cabinet body comprises the cabinet body, and the upper end of described cabinet body is provided with the air vent hole that is communicated with cabinet body interior space, and a ventilation fan is fixed in the upper end of cabinet body, and air vent hole is stated in this Air-exchange fan hood residence.
Adopted such scheme, the air vent hole of the utility model by being communicated with in cabinet body interior space, a ventilation fan is fixed in the upper end of cabinet body, air vent hole is stated in this Air-exchange fan hood residence, during use, forced ventilation effect by ventilation fan, the intrinsic gas of cabinet is aspirated, make extraneous cooling air constantly enter into the cabinet body, these cooling air skim over from the surface of electric elements, take away the heat on the electric elements, thereby avoid the accelerated ageing of electric elements, guarantee the normal useful life of electric elements.
Further, the upper end of described cabinet body also is provided with an overhead guard that covers described ventilation fan, and the side wall surface of this overhead guard is provided with steam vent.When switch cabinet body when outdoor environment uses, by the effect of overhead guard, can prevent that dust or rainwater from directly falling on the ventilation fan, ventilation fan exerts an influence.
Further, the back of axially intersecting of the axial and overhead guard of described steam vent is the acute angle of spending less than 90.The arrangement of steam vent can reduce rainwater as far as possible and enter into overhead guard inside.
Further; between ventilation fan and overhead guard; also be provided with a profile and be pyramidal protective cover; fixedly connected with the inwall of overhead guard in the lower end of this protective cover; between the connecting portion of protective cover and overhead guard, be provided with sealing gasket; the top of protective cover is provided with pore, and the sidewall of described overhead guard is provided with osculum, and this osculum is corresponding with the conical surface of protective cover.By the effect of protective cover, when rainwater enters into overhead guard when inner from steam vent because the outer surface of protective cover is the conical surface, therefore, by the effect of protective cover outside wall surface, can make rainwater along the outer surface of protective cover to dirty, discharge by osculum then.
