Abrégé
(EN)
A pressure relief device for electrical equipment housing, includes a valve body having a pedestal that projects above a mounting flange and a table on the pedestal that supports a two-stage valve assembly that can be sized in diameter independently of the working area of the flange beneath the table. The design is particularly applicable to retrofit applications for large power distribution equipment with the footprint of the pressure relief device fixed by the design of the equipment housings. The first-stage valve opening can be sized substantially as large as vent openings in the housings and the second-stage valve openings can be sized in the desired relationship with the first-stage opening for optimizing valve performance independently of the constraints imposed by the footprint of the device.

一种用于电力设备壳体的减压装置包括一阀体,该阀体具有突起在一安装法兰之上的一底座以及在底座之上的一台面,该台面支承一两级式阀组合件,可独立于台面之下的法兰的工作区来设置该阀组合件的直径。本设计尤其可应用于对大型电力输配设备的翻新应用,其中减压装置的装置覆盖面由设备壳体的设计而固定。第一级阀孔的尺寸可被设置成基本上与壳体中的排放孔一样大,而第二级阀孔的尺寸可被设置成与第一级阀孔具有所需的关系,从而可不受装置的装置覆盖面所施加的限制来优化阀性能。
