Abstract
The utility model discloses a purifier for gas supplying device of switch, comprising a casing(3). The casing (3)inner is equipped with a cavity(7), and the both ends of the casing(3) are respectively equipped with an air drain(8) and an air intake(2). A molecular sieve(4) are installed in the cavity(7) of the casing(3) accessing the air intake(2). The bottom of the molecular sieve(4) is equipped with s strainer(5), and in the cavity(7) of the casing(3) accessing the air drain(8) is equipped a strainer(6). The purifier inner is equipped with a molecular sieve used for filtering moisture and a strainer made of metal titanium used for filtering the granular impurity. The purifier can effectively absorpt the moisture in the sulfur hexafluoride gas, and can filter the granular impurity in the sulfur hexafluoride gas, and can ensure the sulfur hexafluoride gas charged into the switch dry and clean, then makes safe running of the switch operate. The molecular sieve and the strainer make the entire air-filled fore-and-aft process lie in air-proof status, and can evade the sulfur hexafluoride gas injuring the human body by draining into the atmosphere to destruct the atmospheric environment.
Description
Technical field
The utility model relates to a kind of gas cleaning plant, is a kind of switch making-up air device clarifier.
Background technology
The switch of using in order to ensure load on the power equipment allotment and failure removal can normally move use safely, needs when the switch internal gas pressure drops to certain value, splits to close with dry pure sulfur hexafluoride and carries out tonifying Qi.At present, people are pure in order to ensure the sulfur hexafluoride gas drying that charges in the switch, often need to embathe the tonifying Qi pipeline with pure sulfur hexafluoride flushing tonifying Qi pipeline with watery hydrochloric acid, remove pipeline endoparticle shape impurity and moisture purpose to reach.But, exist consuming time longlyer with existing impurities removing method, and be difficult to the effect of effective removal of contamination, and sulfur hexafluoride gas is harmful, directly be discharged into during flushing in the atmosphere and can pollute, and the healthy of workmen arrived in serious threat atmospheric environment.
Summary of the invention
The purpose of this utility model, provided a kind of switch making-up air device clarifier, it is installed between switch and the making-up air device, make switch, clarifier, making-up air device and gas cylinder form a system that envelope is close, both can remove particulate contamination and moisture in making-up air device and the tonifying Qi pipeline effectively, and guarantee that the sulfur hexafluoride gas drying that enters in the switch is pure, but make the switch safe operation, can avoid sulfur hexafluoride gas to enter the atmosphere pollution environment again effectively, influence people's health.
The purpose of this utility model is achieved through the following technical solutions: switch making-up air device clarifier, it has housing, the two ends of housing set out gas port and air inlet respectively, near the air inlet place molecular sieve is installed in the housing, filter screen is installed in the bottom of molecular sieve, near the place, gas outlet screen pack is installed in the housing.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: molecular sieve is the activated carbon molecular sieve.Filter screen is a stainless steel filtering net.Screen pack is the Titanium screen pack.On the air inlet of housing seal cover is installed, seal cover is installed on the gas outlet.
Good effect of the present utility model is: the molecular sieve of filtration moisture and the Titanium screen pack of filtering particle shape impurity are equipped with in its inside, can absorb the moisture in the sulfur hexafluoride gas effectively, filter the particulate contamination in it, can guarantee that the sulfur hexafluoride gas drying that charges in the switch is pure, make the operation of switch trouble free service.And it makes the front and back process of whole inflation be in air-tight state, can avoid sulfur hexafluoride gas to enter atmosphere and destroy atmospheric environment, and human body is damaged.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Switch making-up air device clarifier, it has housing 3, offer cavity 7 in the housing 3, the two ends of housing 3 set out gas port 8 and air inlet 2 respectively, near air inlet 2 places molecular sieve 4 is installed in the cavity 7 of housing 3, filter screen 5 is installed in the bottom of molecular sieve 4, near 8 places, gas outlet screen pack 6 is installed in the cavity 7 of housing 3.Molecular sieve 4 is activated carbon molecular sieves.Filter screen 5 is stainless steel filtering nets.Screen pack 6 is Titanium screen packs.Seal cover 1 is installed on the air inlet 2 of housing 3, seal cover 9 is installed on the gas outlet 8.During tonifying Qi, gas cylinder, making-up air device and switch making-up air device are connected with stainless steel flexible hose successively with clarifier, the switch making-up air device directly is connected with switch with clarifier, the switch of opening all valves in the tonifying Qi path and making-up air device is split to close and is replenished sulfur hexafluoride gas, after the pressure in the air gauge display switch reaches certain numerical value, close the valve on the tonifying Qi path and the switch of making-up air device and stop tonifying Qi.Technical scheme described in the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology.
Claims (5)
