Abstract
The utility model discloses a kind of SF6 density monitors sunshade thermal insulation cover, including inner shell (1), shell (3), with link muscle between inner shell (1) and shell (3)（2）It is fixed, inner shell（1）And shell（3）Between gap length be 8～15 ㎜, draw-in groove (5) is set on the inside of inner shell (1), shell (3) outer surface applies sunshade thermal insulation coating, shell (3) both sides open up the bottom of 10～16 louvres (4), inner shell (1) and shell (3) and open up observation port (6).Using this utility model, the temperature inside SF6 density monitors is little with ambient temperature difference, effectively reduces false alarm phenomenon, it is ensured that the normal operation of main equipment, reduce cost of equipment maintenance.This utility model is particularly well-suited to the sunshade thermal insulation protection of High aititude, high ultraviolet area SF6 density monitors.
Description
Technical field
This utility model is related to a kind of SF6 density monitors sunshade thermal insulation cover.
Background technology
SF6 (sulfur hexafluoride) density monitor is widely used in power equipment, and which passes through gas inside pressure value consersion unit
Body density, plays a part of whether supervision equipment gas leaks, and pressure value is affected to cause numerical value difference by variation of ambient temperature
Situation happens occasionally, and " SF6 gas pressures are low " warning message occurs.The sunshading cover for using at present be monolayer PVC materials and with after
Sunshading cover without hollow out between electrical equipment, when in sun direct projection to sunshading cover, protective cover surface temperature is raised and conducts heat
To inside relay, due to SF6 density monitor small volumes, relay internal temperature is easily caused higher than ambient temperature.Press
According to the operation principle of SF6 density monitors, when relay internal temperature is more than 20 DEG C, relay is mended according to internal temperature
Repay.Ambient temperature is bigger with relay internal difference in temperature, and relay is more to the unreasonable compensation in the direction of reduced pressure, or even
Compensate less than alarming value, it is impossible to reflect the internal gas pressure of equipment itself, cause equipment " SF6 gas pressures are low " to report by mistake
It is alert.False alarm can cause main equipment to be not normally functioning, and cause plant maintenance personnel to judge by accident, increase cost of equipment maintenance.
The content of the invention
The purpose of the present utility model is directed to above-mentioned weak point, there is provided a kind of good SF6 density of sunshade thermal insulation effect
Relay bilayer hollow out sunshade thermal insulation cover.
What this utility model was realized in：Including inner shell 1, shell 3, it is characterized in that between inner shell 1 and shell 3 with link
Muscle 2 is fixed, and the gap length between inner shell 1 and shell 3 is 8～15 ㎜, and draw-in groove 5 is arranged on the inside of inner shell 1, and 3 outer surface of shell is applied
Sunshade thermal insulation coating, 3 both sides of shell open up the bottom of 10～16 louvres 4, inner shell 1 and shell 3 and open up observation port 6.
SF6 density monitors are snapped in this utility model draw-in groove 5 during use.When sunlight, one be by
Sunshade thermal insulation coating is applied in 3 outer surface of this utility model shell, the infrared ray, ultraviolet in most of sunlight is reflected,
Reduce the accumulation of the heat on 3 surface of shell of the sun；Two be this utility model using in double-deck engraved structure, there is air centre
Thermal insulation layer, reduces shell 3 to the conduction of heat of inner shell 1；Three is that 3 both sides of this utility model shell have opened up louvre 4, is accelerated
Air heat-insulation layer is exchanged with extraneous air.
Using this utility model, the temperature inside SF6 density monitors is little with ambient temperature difference, effectively reduces wrong report
Alert phenomenon, it is ensured that the normal operation of main equipment, reduce cost of equipment maintenance.This utility model is particularly well-suited to high sea
Pull out, the sunshade thermal insulation of the regional SF6 density monitors that ultraviolet is strong is protected.
Description of the drawings
Fig. 1 is this utility model structural representation；
Fig. 2 is cross-sectional view of the present utility model.
In figure：1-inner shell, 2-link muscle, 3-shell, 4-louvre, 5-draw-in groove, 6-observation port.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further illustrated.
This utility model includes inner shell 1, shell 3, it is characterized in that being fixed with link muscle 2 between inner shell 1 and shell 3,
Gap length between inner shell 1 and shell 3 is 8～15 ㎜, and draw-in groove 5 is arranged on the inside of inner shell 1, and 3 outer surface of shell applies sunshade thermal insulation
Coating, 3 both sides of shell open up the bottom of 10～16 louvres 4, inner shell 1 and shell 3 and open up observation port 6, this utility model system
The material of work preferably selects PC.
