Description

A kind of SF6 equipment inflation contact switching device special tool
Technical field
The utility model belongs to gas-charging connection conversion equipment technical field, particularly a kind of SF6 equipment inflation contact switching device special tool.
Background technique
Increase along with the electric substation of company's electrical network enlarges, in electric power system, original oil-filled type power equipment (circuit breaker, mutual inductor) is replaced by SF6 type gas-filled type power equipment gradually, and SF6 type gas-filled type power equipment overall performance is good, stable.But along with the increase of working time, the sealability of equipment descends to some extent, and the phenomenon that often leaks air is in operation.If the pressure of SF6 can not in time return to rated pressure, the insulation of power equipment will reduce, and continues operation serious accidents such as dielectric tracking just might take place, and has a strong impact on safety, the reliable operation of electrical network.But because equipment producer model is numerous, cause gas-charging connection also a lot, former is to adopt single inflatable tool, can only connect according to model institute of producer connector at every turn, producer's gas-charging connection can not be general mutually, can't carry out charged inflation to it with supporting gas tube, efficiency of construction is lower.CN 202501124 U disclose a kind of transit joint for the work of SF6 gas delivery, comprise a joint matrix, and an end of joint matrix is provided with female adapter, and the other end of joint matrix is provided with outside thread D worker LO joint.But the corresponding joint that uses of described transit joint for the work of SF6 gas delivery is limited after all, and the probability that appearance can't transition be used is bigger, and loses easily.
The model utility content
The utility model purpose is to provide a kind of safe SF6 equipment inflation contact switching device special tool easy to use, comfortable.
To achieve these goals, the technical solution adopted in the utility model is: a kind of SF6 equipment inflation contact switching device special tool, it comprises six-way valve, crossover sub and producer's gas-charging connection, four valve ports of described six-way valve both sides arrange crossover sub, described crossover sub connects described producer gas-charging connection, the anterior port of described six-way valve arranges pressure instrument, and described six-way valve afterbody port arranges the pipeline that connects charger.
Described pipeline connects the SF6 gas cylinder by decompression table.
Described crossover sub is set to nut connector, and described nut connector one end arranges internal thread, and the other end is provided with outside thread.
The utility model comprises six-way valve, crossover sub, producer's gas-charging connection and the pipeline that connects charger, whole device forms an integral body, portably use conveniently, avoided adopting in the original using process single inflatable tool to cause the incompatible phenomenon of gas-charging connection of different manufacturers, can realize charged inflation, improve efficiency of construction; Four valve ports of described six-way valve both sides arrange crossover sub, described crossover sub connects described producer gas-charging connection, described crossover sub often is the gas-charging connection of the different manufacturers different size of use, solved in the daily SF6 of carrying out tonifying Qi process, the unmatched obstacle of gas-charging connection, the anterior port of described six-way valve arranges pressure instrument, accuracy to judging in duct cleaning and the gas replenishment process before can guaranteeing to inflate, everything goes well with your work lays a solid foundation in order to inflate, described pipeline connects the SF6 gas cylinder by decompression table, guarantee that the pressure of SF6 can in time control in rated pressure, the insulating properties that keeps power equipment, avoid having ensured the safety of system because insulating properties reduces the serious accidents such as dielectric tracking that cause, reliable operation; Described crossover sub is set to nut connector, described nut connector one end arranges internal thread, the other end is provided with outside thread, can be well suited for the male threaded stub of most gas-charging connection, improved adaptability, solved connection back and forth and caused the aging problem that causes of sealing gasket, connected fast simple.The utility model is by installing the crossover sub of a cover six-way valve and producer's gas-charging connection afterbody additional, the gas-charging connection of different manufacturers different size is united, carry out in the SF6 tonifying Qi process daily, reduced the unmatched obstacle of gas-charging connection, both improve working efficiency, guaranteed the reliable operation of equipment again.After the project implementation, the time when shortening each model filling apparatus gas of scene, also reduced personnel and vehicle One-Shift Costs, comprehensively improved economic benefit.The utility model is simple in structure, easy to use, is convenient to generally promote the use of.
