Description
Technical field
The present invention relates to a kind of combined electrical apparatus air leakage point and quickly searches device.
Background technique
With greatly developing for electric utility, SF6 gas is widely used in its excellent insulation performance and arc extinction performance
In electrical equipment, the operation of GIS also obtains swift and violent development.But the leakage of GIS not only will affect the normal operation of equipment, more
The harm on body and on life can be brought to service personnel.So being hunted leak to FS6 for fast accurate just seems especially heavy
It wants.And existing detection mode is directly to be detected using the concentration detector of SF6 gas close to equipment, because of not confined space
Cause detection inaccuracy.
Summary of the invention
The purpose of the present invention is to provide a kind of combined electrical apparatus air leakage points quickly to search device, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme:
A kind of combined electrical apparatus air leakage point quickly searches device, including cover, sealing ring, top sealing ring, top connecting column, turns
Axis, vacuum pump, SF6 gas concentration detector, cavity, top vent, the cover bottom one week integrally formed with sealing ring,
The covering on top is equipped with top sealing ring, and top connecting column, the top connection are equipped at the top of the top sealing ring
Column top is equipped with vacuum pump by shaft, is equipped with SF6 gas concentration detector at the top of the vacuum pump, inside the cover
Cavity is offered, offers top vent in the top connecting column, and top vent is connected with vacuum pump.
Preferred: it further includes connection pedestal, screw thread and rubber hose, institute that the combined electrical apparatus air leakage point, which quickly searches device,
It states and screw thread, the company is offered with pedestal connection, the connection base top outside is connect by shaft at the top of the connecting column of top
It connects pedestal to be connected by screw thread with vacuum pump bottom, passes through rubber hose in the top vent opened up in the top connecting column
It is connected across connection pedestal with vacuum pump.
Preferred: the cover and sealing ring are all made of the production of viscous silica gel material.
The beneficial effects of the present invention are: the present invention has rational design, the accurate positionin of device air leakage point can be quickly searched, and mention
On-line treatment method out can ensure the normal operation of equipment, and being capable of effective safeguard work personnel health and life security
It is not encroached on.
