Description
Technical field
The present invention relates to a kind of outlet black box that significantly can improve FLN36 and SFG on-load switch degree of protection, belong to switching technique field.
Background technology
On-load switch is the vitals in power distribution equipment, and the housing of conventional on-load switch (as FLN36, ABB-SFG) generally adopts reinforced epoxide resin vacuum to pour into a mould and forms, and inside fill SF6 gas, on-load switch top is connected with bus, bottom leading-out wire.The position be connected with outlet due to on-load switch is all naked leakage electric component or current－carrying conductor, there is no seal approach, causing the IP degree of protection of existing on-load switch, not high enough (outdoor degree of protection is generally IP33, indoor is IP30), the impact of environmental factor is very easily subject to during operation, in particular for heavy industry, chemical industry, the switchgear of mountain area, rivers, coastal area and humid tropics climatological region, the insulation flashover accident occurred all is caused by the filth of moisture, condensation, dust and chemical industry mostly.Therefore, the sealing property improving on-load switch and outlet connecting portion, to the failure rate reducing distribution network, guarantees that the safe operation of electric power system is significant.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of load switch wire-outlet black box is provided, to improve the degree of protection of on-load switch, ensure the safe operation of electric power system.
Problem of the present invention is realized by following technical scheme:
A kind of load switch wire-outlet black box, formation comprises outlet current－carrying conductor, the upper end of described outlet current－carrying conductor connects post by overlap joint fixed screw with the outlet of on-load switch and is connected, lower end is docked with the prefabricated connection-peg of outlet, the outer surface of outlet current－carrying conductor is provided with prefabricated silicone rubber insulation layer, the one side that described prefabricated silicone rubber insulation layer is relative with the epoxy package of on-load switch is provided with the seal boss of annular, prefabricated silicone rubber insulation layer also leaves overlap joint fixed screw installing hole, in described overlap joint fixed screw installing hole, silicone rubber seal plug is installed.
Above-mentioned load switch wire-outlet black box, the bottom of described prefabricated silicone rubber insulation layer is provided with electrification in high voltage attention device, described electrification in high voltage attention device comprises electric capacity, current-limiting resistance and light-emitting diode, and three is connected in series rear one end leading-out wire current－carrying conductor, a terminate ground wire.
Above-mentioned load switch wire-outlet black box, overlap joint fixed screw installing hole interference fit on described silicone rubber seal plug and prefabricated silicone rubber insulation layer, the inwall of described overlap joint fixed screw installing hole is provided with cannelure, the sidewall of silicone rubber seal plug is provided with the annular protrusion matched with the cannelure overlapped on fixed screw installing hole inwall.
The present invention utilizes prefabricated silicone rubber insulation layer and silicone rubber seal plug to be sealed by outlet current－carrying conductor, outlet current－carrying conductor and external environment are isolated, improve the class of insulation and the degree of protection of on-load switch, completely eliminate the environmental factors such as humidity, temperature and filth to the harmful effect of insulation property, ensure that the safe operation of electric power system.Electrification in high voltage attention device can send warning light signal when outlet current－carrying conductor is charged, reminds maintainer to take care.The present invention adopts the method for cast to make, and achieves the standardization of product, modularization, is convenient to processing and assembling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is structural representation of the present invention;

Embodiment
Referring to Fig. 1 ~ Fig. 3, traditional F LN36, to there is sealing property in ABB-SFG switchgear bad, easily enters dust, be subject to external environment influence, the shortcoming that electric accident rate is high.The present invention includes outlet current－carrying conductor 10, prefabricated silicone rubber insulation layer 9, silicone rubber seal plug 2, the outlet of outlet current－carrying conductor 10 and on-load switch is connect post and wraps up by prefabricated silicone rubber insulation layer 9 and silicone rubber seal plug 2, prevent extraneous moisture, dust and the filthy outlet damaging outlet current－carrying conductor 10 and on-load switch from connecing post, electrification in high voltage attention device 12 reminds service work personnel to take care timely and effectively.
The present invention is the European plugs of prefabricated silicon rubber, and assembly adopts the form of standard cell combination, is convenient to processing and assembling.
This assembly fundamentally solves the sealing problem of the main current-carrying part of on-load switch, the IP degree of protection of product is made to be promoted to IP67 by IP30, and have electrification in high voltage attention device 12 to do charged warning, prevent charged misoperation, effectively ensure the operational security of maintainer.And the present invention in prefabricated silicone rubber insulation layer, even if do not connect power supply, also can make diode displaying because of components and parts wherein and line because of the reason of high voltage induction by previously prepared for electrification in high voltage attention device 12.
After the present invention uses sealing assembly, even if there is flood, on-load switch also can normally run at short notice, and can be adapted to the installation environment of High aititude.
