Abstract

The utility model discloses an SF6 gas on-line micro-water density detection device. The device comprises a one-way valve (4); the one-way valve (4) is connected with a gas passage (5); the gas passage (5) is connected to a density detection meter (2) and a double-throw switch (3); and the other end of the double-throw switch (3) is connected with an on-line micro-water density detection device (7). The utility model has the benefits that the gas passage of an early-stage product can be renewed and replaced, the device can serve supervision function on indication efficiency of the operation of an electrified density test relay of equipment of the early-stage product, and the micro-water content value of SF6 gas, thereby reducing problems such as equipment outage, SF6 gas run off during gas micro-water test, and the like which are caused by frequent equipment operation maintenance tests, and providing conditions for reliable operation of electric equipment and effective resource maintenance, that is obtaining win-win benefits.

Description

The online little water-mass density pick-up unit of SF6 gas
Technical field
The utility model relates to a kind of little water-mass density pick-up unit, the online little water-mass density pick-up unit of particularly a kind of SF6 gas.
Background technology
SF6 (sulfur hexafluoride) normal temperature and pressure is the nontoxic gas of no color or smell down.Do not burn.To thermally-stabilised, the chemical property torpescence.Generally adopt the little water of off-line measurement, density at present, need to exit, numerous and diverse process such as tonifying Qi, troublesome poeration and dangerous, also there are online little water and Density Detection product single, sensor life-time is short, lacks intellectuality, can't check the variation of little water in arbitrfary point and density, daily servicing amount height, the waste resource.
Summary of the invention
At the shortcoming that the little water-mass density of existing off-line detects, the utility model provides a kind of SF6 gas online little water-mass density pick-up unit.
To achieve these goals, the measure taked of the utility model:
The online little water-mass density pick-up unit of a kind of SF6 gas, comprise retaining valve, retaining valve links to each other with air flue, air flue is connected respectively to Density Detection table and two-way switch, the other end of two-way switch links to each other with online little water proving installation by air flue, air flue links to each other with electrical equipment simultaneously, and electrical equipment, Density Detection table, two-way switch, retaining valve, air flue and online little water proving installation are fixed together;
The link position that air flue links to each other all is provided with threeway, and the material of O-ring seal is an ethylene-propylene diene copolymer;
Electrical equipment, Density Detection table, two-way switch, retaining valve, air flue and online little water proving installation are to be fixed together by set bolt.
The beneficial effects of the utility model: make the early production gas circuit obtain upgrading and substitute, it is telltale simultaneously can also to carry out the micro-water content value of usefulness, SF6 gas of live testing density monitor action indication to its equipment, thereby reduce because of equipment frequent operation checking experiment, the problems such as SF6 gas that the equipment that causes is stopped transport, the little water test of gas is run off are for the power equipment reliability service has obtained the effective conservation of resources and benefit doulbe-sides' victory.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
The online little water-mass density pick-up unit of a kind of SF6 gas, comprise retaining valve 4, retaining valve 4 links to each other with air flue 5, air flue 5 is connected respectively to Density Detection table 2 and two-way switch 3, the other end of two-way switch 3 links to each other with online little water proving installation 7 by air flue 5, air flue 5 links to each other with electrical equipment 1 simultaneously, and electrical equipment 1, Density Detection table 2, two-way switch 3, retaining valve 4, air flue 5 are fixed together with online little water proving installation 7.All link positions of link position that all link to each other with air flue 5 link to each other by threeway, and the unified ethylene-propylene diene copolymer raw material that adopts of O-ring seal has strengthened sealing like this, makes more reliable performance.
The online little water-mass density device of SF6 gas installs humidity sensor and the pressure transducer moisture in the on-line monitoring SF6 gas simultaneously additional, the action of temperature and density monitor, can start low pressure alarming automatically by preset value or user's set-point, little water exceeds standard and reports to the police and blocking device, show real time data and draw state variation tendency figure automatically by daemon software. this on-line monitoring system, change traditional time-consuming, bothersome, the off-line measurement mode of taking gas, measure little water of SF6 gas and variable density in real time accurately, react little water, the historical variations trend of density content, enter workstation by the teletransmission of R485 bus, user side is equipped with on-line monitoring software, the user can check the little water and the density of arbitrfary point easily, carry out preventive maintenance according to the datamation state, for the normal operation of power equipment escorts.
The beneficial effects of the utility model: make the early production gas circuit obtain upgrading and substitute, can also carry out the usefulness of live testing density monitor action indication, the micro-water content value supervisory role of SF6 gas to its equipment simultaneously, thereby reduce because of equipment frequent operation checking experiment, the problems such as SF6 gas that the equipment that causes is stopped transport, the little water test of gas is run off. For the power equipment reliability service has obtained the effectively conservation of resources and benefit doulbe-sides' victory.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
