Description
Technical field
It is especially a kind of for gas insulation switch cabinet on-load switch pressure test the utility model is related to power domain
Seal line apparatus.
Background technology
Gas insulation switch cabinet is using hypobaric SF6 Gas, N2 Gas or mixed gas are as switchgear
Dielectric, with vacuum or SF6 For arc-extinguishing medium, the medium pressure elements such as busbar, breaker, disconnecting switch concentration is enclosed in case
In body, integrated use modern times insulation technology cut-offs technology, manufacturing technology, sensing technology, the collection intelligently control of digital technology production
System, protection, monitoring, measurement, communication are in the new high-tech product of one.Gas insulation switch cabinet is before being taken into use, it is necessary to right
It carries out industrial frequency AC pressure test, judges that the energy of various overvoltage is born in gas insulation switch cabinet insulation by pressure test
Power, this experiment is to ensureing that gas insulation switch cabinet safe operation has important meaning.
It is compact-sized due to gas insulation switch cabinet, between coupling box phase and phase, coupling box and cabinet
Air gap distance between body is inadequate, when carrying out industrial frequency AC pressure test, coupling box to cabinet and phase and phase it
Between insulation breakdown phenomenon or insulation edge flashing phenomenon easily occurs, be not achieved as defined in test voltage value, be also easy to cause gas
Body insulated switch cabinet is damaged.
The content of the invention
Show to overcome existing gas insulation switch cabinet that insulation breakdown easily occurs when carrying out industrial frequency AC pressure test
As or insulation edge flashing phenomenon deficiency, the utility model, which provides, a kind of is used for the pressure-resistant examination of gas insulation switch cabinet on-load switch
The envelope line apparatus tested, the envelope line apparatus for being used for gas insulation switch cabinet on-load switch pressure test have blocked putting for the air gap
Power path efficiently solve the problems, such ass coupling box during pressure-resistant to closing on cabinet electric discharge.
The technical solution of the utility model is：A kind of envelope for gas insulation switch cabinet on-load switch pressure test is traditional thread binding
It puts, including metal connecting plate, the metal connecting plate one side is connected with resistance to voltage cable, and resistance to voltage cable is internally provided with high-potting cable copper
Line, the connection of metal connecting plate opposite side is there are three plug insulated envelope, and metal connecting plate surface is equipped with silica gel sheath.
The metal connecting plate is equipped with metal connecting plate line nose, and the plug insulated envelope passes through metal screw and metal connecting plate
Line nose is connected.
The utility model has the advantages that：Due to taking said program, plug insulation is fixed on metal connecting plate
Big envelope when carrying out pressure test, on plug insulated envelope insertion gas insulation switch cabinet on-load switch coupling box, is handed over
The dielectric strength at coupling box is enhanced when flowing pressure-resistant, so as to prevent phase and phase and relatively between there is air insulation
Breakdown or flashover, play a very good protection.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic diagram of silica gel sheath.
1- silica gel sheaths in figure；The resistance to voltage cables of 2-；3- plugs insulated envelope；4- high-potting cable copper wire；5- metal connecting plates；
6- insulation closure；7- metal connecting plate line noses；8- metal screws.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Fig. 1, Fig. 2, a kind of envelope line apparatus for gas insulation switch cabinet on-load switch pressure test, including gold
Belonging to connecting plate 5,5 one side of metal connecting plate is connected with resistance to voltage cable 2, and resistance to voltage cable 2 is internally provided with high-potting cable copper wire 4,
It can be directly connected on test voltage mutual inductor, not only added security but also improve test efficiency.5 opposite side of metal connecting plate connects
It connects there are three plug insulated envelope 3, plug insulated envelope 3 is made of the silicone rubber sleeve material of height insulation, and when ac voltage withstanding enhances
Dielectric strength at coupling box, prevent phase and phase and relatively between there is air insulation breakdown or flashover,
Play a very good protection, and plug the slightly wide rear end bore of 3 front end bore of insulated envelope slightly it is narrow be suitable for plug fix
On coupling box.Plug insulated envelope 3 is internally provided with metal screw 8, and the metal connecting plate 5 is equipped with metal connecting plate line
Nose 7, metal screw 8 are connected by screw with metal connecting plate line nose 7, and are plugged 3 outside of insulated envelope and be equipped with insulation closure.It is described
5 surface of metal connecting plate is equipped with the silica gel sheath 1 of insulation, is closed when can prevent pressure-resistant and discharged cabinet flashover.
When carrying out pressure test to switchgear, three plug insulated envelopes 3 of the envelope line apparatus are inserted into gas-insulated
On switchgear on-load switch coupling box, internal metal screw 8 is made to be adequately exposed to coupling box interior metal
High-potting cable copper wire in resistance to voltage cable is connected on test voltage mutual inductor by structure after fixing good position, then split
It closes cabinet and carries out pressure test.The envelope line apparatus avoids coupling box to cabinet due to insulation distance during pressure test
Gas-insulated punch-through not enough occurs or insulation edge flashing phenomenon, present apparatus structural insulation performance are better than common electricity
Cable greatly improves work efficiency.
