Abstract
The utility model provides a rain cover for a density relay of a sulfur hexafluoride combined switch. The rain cover comprises a cover body, a rain cover fixation plate and a glass plate, wherein the relay is arranged in the cover body, and ventilators are arranged on the side wall of the cover body. The downward ventilators are arranged on the side wall of the rain cover and the vapor in the rain cover or the rain drops formed by the vapor in the rain cover flows out through the downward ventilators of the rain cover by the convection natural wind, so as to exert the rainproof effect, and simultaneously the service life of the relay is prolonged, moreover the rain cover is simple in structure, convenient to install and better to use.
Description
Technical field
The utility model relates to a kind of high pressure and ehv power transmission switchgear, relates in particular to the rain cover of the density monitor of outdoor type unit switch (GIS).
Background technology
The sulphur hexafluoride unit switch is widely used at high pressure and ehv power transmission system break road device.The reliable and secure operation that how to guarantee the sulphur hexafluoride electric product has become one of vital task of power department.Sulfur hexafluoride gas density relay is one of key element of sulphur hexafluoride electric switch, it is used for detecting the variation of sulfur hexafluoride gas density in the sulfur hexafluoride electrical equipment body, and its performance quality directly has influence on the reliable and secure operation of sulfur hexafluoride electrical equipment.The rain cover of the common usefulness of prior art all is not with ventilating opening, in routine use because of daytime and when night, the temperature difference XOR rained, easily at the inner steam that forms of rain cover, and steam can't timely and effectively be got rid of, this will density monitor, valve body etc. causes certain corrosiveness, also can produce to the sight glass plate effect of atomizing, thereby the user of service is difficult for observing inner sulfur hexafluoride density relay numerical value, therefore from practice, be necessary the structure of rain cover is improved.
The utility model content
The purpose of this utility model is to provide a kind of rain cover of outdoor type density monitor that can available ventilation.
For achieving the above object, the utility model is used for the rain cover of the density monitor of sulphur hexafluoride unit switch, mainly comprises cover body, rain cover fixed head and glass plate, is provided with relay in the described cover body, and wherein, described faceshield side wall is provided with ventilating opening.
Further, described ventilating opening is bent downwardly from the faceshield side wall inclination and extends to form.
Further, described ventilating opening is strip.
Further, described ventilating opening is arranged on three sidewalls of cover body.
Further, described ventilating opening is made as respectively three on faceshield side wall.
Further, described rain cover fixed head is arranged on the bottom of cover body, and it locks on sulfur hexafluoride density relay with cover body by bolt.
Further, described glass plate is arranged on the cover body side, is connected with cover body by bolt.
Further, described ventilating opening be shaped as semicircle or square.
Further, described ventilating opening is arranged on two sidewalls of cover body.
Further, described ventilating opening is being made as respectively more than 1 or 2 or 3 on the faceshield side wall.
The beneficial effects of the utility model: the rain cover of the density monitor of the utility model sulphur hexafluoride unit switch, this rain cover sidewall is provided with ventilating opening down, natural wind by convection current can be taken away the steam in the rain cover, or the raindrop that the steam in it forms are flowed out from bucker ventilating opening down, played rainproof effect, also increased the useful life of relay simultaneously, and this rain cover has been simple in structure, be convenient to install, result of use is good.
