Abstract
The utility model relates to the field of overhauling and maintenance of a power system, in particular to a multifunctional inflation switching device. According to the technical scheme, the device comprises a pressure reducing valve, a pipeline and an inflation port, wherein a gas bottle is connected with equipment through the pressure reducing valve, the pipeline and the inflation port; a gas drying dust remover is arranged between the pressure reducing valve and the pipeline; the tail end of the pipeline is connected with a three-way exhaust valve; and a check ball valve is arranged between the three-way exhaust valve and the inflation port. The device has the beneficial effects that: the inflation port is convenient and fast to connect; the check ball valve is adopted at the tail end; the adaptive pipeline is adopted for connection; the working efficiency is increased; strict control over water content in an inflation process can be realized through a gas dryer and the three-way exhaust valve; the inflation quality is guaranteed; and the actual application effect that one box can be used for all purposes can be realized through various types of inflation ports.
Description
Technical field:
The utility model relates to electric power system repair and maintenance field, the multi-functional inflation switching device of the tonifying Qi maintenance work of particularly a kind of electric power system GIS equipment and SF6 circuit breaker.
Background technology:
In electric power system, the SF 6 high-voltage electric equipment, in running because the device manufacturing process problem, and day-to-day operation monitoring such as water content are tested, tend to cause body interior pressure to reduce, density descends, thereby need periodically carry out inspection tonifying Qi work.And not having simple and easy fast and be suitable for the quick air-inflating apparatus of dissimilar producers equipment in the market, the on-the-spot conventional tube connected modes such as iron wire colligation that adopt make the loaded down with trivial details and charge-air mass of tonifying Qi work to guarantee more.
Summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of multi-functional inflation switching device is provided, and realizes the pipeline butt joint fast, avoids pipeline to reverse, and carries out gas replenishment process moisture in real time and handles, and adaptive inflation interface comprehensively is provided.
Its technical scheme is: comprise pressure-reducing valve, pipeline, inflation interface, gas cylinder is through pressure-reducing valve, pipeline, inflation interface connection device, the dry deduster of gas is set in the middle of described pressure-reducing valve and the pipeline, the terminal three-way exhaust valve that connects of described pipeline is provided with the check ball valve between three-way exhaust valve and the inflation interface.
The beneficial effects of the utility model are: the inflation interface is convenient and fast connection, tail end adopts the check ball valve, adopt adaptive type pipeline to connect, increase work efficiency, can realize that by gas-drying apparatus and three-way exhaust valve the strictness to moisture is controlled in the gas replenishment process, guarantee charge-air mass, all types of inflation interfaces can be realized one case all-round practical effect.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model comprises pressure-reducing valve 2, the pipeline 4 of the special-purpose armouring inflation of a cover, inflation interface 7, gas cylinder 1 is through pressure-reducing valve 2, pipeline 4, inflation interface 7 connection devices 8, described pressure-reducing valve 2 and the pipeline 4 middle dry dedusters 3 of gas that are provided with, the described pipeline 4 terminal three-way exhaust valve 5 that connect are provided with check ball valve 6 between three-way exhaust valve 5 and the inflation interface 7.
Gas replenishment process, gas is after pressure-reducing valve is derived, at first pass through the dry deduster 3 of gas of SF6, guarantee the real-time processing of moisture, connecting line, open three-way exhaust valve 5, residual air in the pipeline is discharged, achieve a butt joint with inflation interface 7 fast by check ball valve 6, ball valve sealing can realize that the nothing in the pipeline installation process reverses, various types of inflation interfaces can satisfy the inflation interface butt joint of the dissimilar SF6 equipment in current market.
