Description
Technical field
The utility model relates to a kind of GIS, particularly relates to a kind of with SF
6/ N
2mist is the novel GIS of dielectric.
Background technology
Adopt pure SF
6gas as the gas-insulated switch (gas insulated switchgear, be called for short GIS) of dielectric because the advantage that its floor space is little, reliability is high is in electric power system.SF
6gas also exist low temperature easily liquefy, higher to technological requirement, expensive, there is the problems such as stronger greenhouse effect, a large amount of SF that current Chinese scholars have studied
6substitute gas, but be difficult in a short time find out and can replace SF completely
6and to the gas that environment is safe from harm, how to reduce pure SF
6gas is also the problem solved in present field as the gas-insulated switch insulating gas of dielectric to the harm of environment.
Utility model content
The purpose of this utility model is to provide a kind of with SF
6/ N
2mist is the novel GIS of dielectric, can replace pure SF
6the substitute medium of gas, sets up containment vessel outside GIS chamber, reduces SF
6gas is to the harm of air.
The protective layer of the utility model further object solution prior art coil outside and insulating barrier easily scratch and are short-circuited, and the problem of not locating very well when coil is fixed.
The utility model adopts following technical proposals:
A kind of with SF
6/ N
2mist is the novel GIS of dielectric, comprise multiple air chamber, airtight, insulation mutually between multiple air chamber, also include mutual inductor coil housing and coil, the chamber of annular is provided with in described mutual inductor coil housing, be provided with coil in described chamber, described coil is fixed in chamber by organic gel; The chamber peripheral hardware of the annular of described solenoid housing has coil cover plate, and described coil cover plate is fixed by screws on solenoid housing; Also dead ring is provided with between the inner ring of the annular chamber of described solenoid housing and coil cover plate.
The number of described coil is at least one, is provided with insulation board between described coil and coil.
Described solenoid housing is metal shell.
Insulating gas in described air chamber is SF
6and N
2gaseous mixture.
Gas-insulated switch of the present utility model can adopt pure SF reaching tradition
6gas is as the function of the gas-insulated switch of dielectric.Due to N
2stable chemical nature, and be easy to obtain, the cost of dielectric can be reduced, to reduce SF
6discharge, and then reduce impact on environment, be applied in lower temperature environment.Further set up mutual inductor coil housing and coil at insulator, solve the circulation problem that coil is outside reliably, the electric current on housing can be blocked by increase dead ring well, ensure that the certainty of measurement of coil and jamproof ability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The GIS of current whole group is divided into multiple air chamber, is opened by different element separate, seals completely between each air chamber, is convenient to recovery and the inflation/deflation of gas, can reduces power failure range during maintenance, is conducive to installing and enlarging work.Wherein every section of bus is divided into several air chamber, and circuit breaker is also divided into body air chamber, CT air chamber, disconnector cabinet, lightning arrester air chamber, circuit PT air chamber etc., seals completely between each air chamber.
A kind of with SF
6/ N
2mist is the novel GIS of dielectric, comprises multiple air chamber, and airtight, insulation mutually between multiple air chamber, the insulating gas in described air chamber is SF
6and N
2gaseous mixture.For better increasing insulated enclosure effect, as shown in Figure 1, the utility model has additional mutual inductor coil housing 1 and coil 2 at disc insulator, the chamber 8 of annular is provided with in described mutual inductor coil housing 1, be provided with coil 2 in described chamber 8, described coil 2 is fixed in chamber by organic gel 6; Chamber 8 peripheral hardware of the annular of described solenoid housing 1 has coil cover plate, and described coil cover plate 5 is fixed on coil housing, on 1 by screw 7; Dead ring 4 is also provided with between the inner ring of the annular chamber 8 of described solenoid housing and coil cover plate.The number of described coil is at least one, is provided with insulation board 3 between described coil and coil.Described solenoid housing 1 is metal shell.
Good protection coil 2 is coil 2 protective layer will be caused to break because of friction vibrations in assembling; Fixed form is firm when can not should be GIS vibrations there is relative vibration and causes the inaccurate of measurement data in coil 2, and structure is simple, the flexible and changeable coil 2 being applicable to various structures size; The fixed form screw 7 of solenoid housing 1 or pin are fixed simple and reliable, and coil 2 vibrations in surface add the reliability of product well, and the accuracy measured of coil 2 and reliability.The utility model also solves the outside circulation problem of coil reliably, can be blocked the electric current on housing well, ensure that the certainty of measurement of coil 2 and jamproof ability by increase dead ring 4.
Traditional GIS is the pure SF filling certain air pressure
6gas, in view of SF
6gas also exist low temperature easily liquefy, higher to technological requirement, expensive, there is the problems such as stronger greenhouse effect, be difficult in a short time find out and can replace SF completely
6and to the gas that environment is safe from harm, the utility model then proposes the SF by filling certain air pressure in each air chamber
6/ N
2mist, wherein because circuit breaker air chamber operational environment is comparatively severe, require higher to dielectric, the air pressure filled is greater than other air chamber.Disc insulator plays support and electric insulation effect to conductor, also plays sealing function to single air chamber simultaneously.So adopt SF
6/ N
2mixed gas insulation is the GIS of dielectric, can guarantee that equipment normally runs, and can alleviate pure SF simultaneously
6the problem brought.
