Abstract
The invention discloses a cooler of a medium-voltage switchgear. The cooler is fixed at the top end of a pressure releasing channel of a switch cabinet, the interior of the cooler is connected with the pressure releasing channel, and the cooler comprises at least two cooling assemblies and a ventilating assembly which are arranged on the lower portion and a pressure releasing plate which is arranged at the top. Each cooling assembly comprises a framework, a multi-layer V-shaped screen arranged in the framework and fixing plates used for fixing the upper end and the lower end of the screen. The distribution directions of the multi-layer V-shaped screens arranged in the at least two cooling assemblies are perpendicular mutually. The ventilating assembly is a framework, and the screens are arranged on four walls on the periphery of the ventilating assembly. The cooler is arranged on the pressure releasing channel of the switch cabinet and with two ends sealed, and during arcing in a switch chamber, scorching grains and gases are cooled and filtered through the cooler and then are released into the air, and safety of operation staffs in a whole power distribution house is ensured.
Description
Technical field
The present invention relates to the cooling of the hot gas that the internal arc fault of medium voltage switchgear equipment produces.Can be widely used in the closed distribution houses such as boats and ships, offshore platform, nuclear power station uses.
Background technology
Along with the progress of society, the fail safe of medium voltage switchgear equipment internal arc fault more and more comes into one's own.But by existing national standard and IEC standard, if scorching hot particle and hot gas that the internal arc fault produces directly are emitted on power distribution room within doors, also can only ensure the safety of the operating personnel in the 800mm scope around the switch cubicle that breaks down, and the safety that exceeds the personnel of this scope in power distribution room can not get ensureing.Present safest method is that hot gas that the internal arc fault is produced is by extending to outdoor discharging by the metal enclosed pressure release passage that consists of.But the power distribution room in some place such as nuclear power station, offshore platform, boats and ships etc., because being subjected to the structural constraint in house directly to discharge hot gas outside the room, scorching hot particle and gas that the internal arc fault produces can only directly be emitted on power distribution room within doors, and this is within doors staff's security presence hidden danger.
Summary of the invention
Technical problem to be solved by this invention is to solve the problem that hot gas that prior art medium voltage switchgear equipment internal arc fault produces may cause casualties, provide a kind of make scorching hot particle and gas in advance cold filtration discharge again the medium voltage switchgear equipment cooler of support personnel's safety to greatest extent.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the medium voltage switchgear equipment cooler, it is characterized in that, described cooler is fixed on the releasing channel of switch cabinet top, its inside and pressure release passage communicate, and described cooler comprises the pressure relief plate at cooling package, ventilation assembly and the top of bottom.
Preferably, described cooling package comprises a framework, is located at the multilayer V-type web plate in the framework and is used for the fixed head at fixed network board two ends.
Preferably, described cooler comprises at least two cooling packages, and the arragement direction of multilayer V-type web plate is mutually vertical in these described at least two cooling packages.
Preferably, described ventilation assembly is a framework, and its peripheral wall is web plate.
Preferably, described ventilation assembly is fixedly mounted on the described cooling package; Being preferably riveting method, can also be other fixed form that it may occur to persons skilled in the art that certainly.
Preferably, described cooler also comprises the pressure relief plate at its top, and pressure relief plate is being fixed by the mode that air-flow is opened.
Preferably, described pressure relief plate is fixed in the bolt mode.
Advantage of the present invention is:
1. cooler is installed on the pressure release passage of closed at both ends of switch cubicle, and during the inner arcing in switch gear room, scorching hot particle and gas are discharged in the air by behind the cooler cold filtration, guarantee within doors operating personnel's safety of whole power distribution room.
The switch cubicle that cooler is installed need not by pipeline hot gas to be discharged power distribution room, and the scope of application is more extensive, such as nuclear power station, offshore platform, boats and ships etc.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Such as the described medium voltage switchgear equipment cooler of Fig. 1-Fig. 4 preferred embodiment,
Medium voltage switchgear equipment cooler 20 is fixed on pressure release passage 11 tops of switch cubicle 10, and its inner and pressure release passage 11 communicates, and two cooling packages 23 bottom cooler 20 comprises, is riveted on ventilation assembly 22 on the cooling package 23 and the pressure relief plate 21 on top; Wherein, cooling package 23 comprises a framework 231, is located at the multilayer V-type web plate 235 in the framework 231 and is used for the fixed head 234 at fixed network board two ends about in the of 235; Ventilation assembly 22 is a framework 221, and its peripheral wall is that web plate 222 is riveted on the framework 221, and in the preferred embodiment, the aperture of web plate is less than 1mm, and the size of ventilation assembly 22 is identical with cooling package 23, the cross-ventilation when being used for the switch cubicle normal operation.
In the preferred embodiment of the present invention, medium voltage switchgear equipment cooler 20 comprises at least two cooling packages, the arragement direction of the multilayer V-type web plate in these at least two cooling packages is mutually vertical, for laterally arranging, the multilayer V-type web plate in another cooling package is for vertically arranging such as the multilayer V-type web plate in the cooling package.
In the another preferred embodiment of the present invention, the pressure relief plate 21 on medium voltage switchgear equipment cooler top is being fixed by the mode that air-flow is opened, as being fixed on cooling package or the ventilation assembly in the bolt mode, certainly, can also be those skilled in the art commonly use other can realize the fixed form opened by air-flow.The pressure relief plate of cooler is that level covers on the ventilation assembly when switch cubicle works, and can prevent that foreign matter from being entered by the switch cubicle top with vertical dripping.In case inside switch cabinet has arc fault, pressure relief plate can be opened by air-flow, guarantees that the switch cubicle internal pressure discharges rapidly.
Certainly, above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all Spirit Essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
