The load switch lead-out sealing assembly seals the wire-outlet current carrying conductor through the prefabricated silica rubber insulating layer and the silica rubber sealing plug, isolates the wire-outlet current carrying conductor from the external environment, improves protection level of the load switch, thoroughly eliminates bad influence on insulating performance caused by environment factors of humidity, temperature, dirt and the like and ensures safe operation of a power supply system.
Description
Technical field
The present invention relates to a kind of outlet black box that can significantly improve FLN36 and SFG on-load switch degree of protection, belong to the switching technique field.
Background technology
On-load switch is the vitals in the power distribution equipment, on-load switch commonly used (as FLN36, housing ABB-SFG) is general to adopt reinforced epoxide resin vacuum cast to form, in fill SF6 gas, on-load switch top is connected with bus, the bottom leading-out wire.Because the position that on-load switch is connected with outlet all is naked electric leakage gas element or current, there is not seal approach, causing the IP degree of protection of existing on-load switch, not high enough (outdoor degree of protection generally is IP33, indoor is IP30), very easily be subjected to Effect of Environmental 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 that takes place is all caused by moisture, condensation, dust and chemical industry filth mostly.Therefore, improve the sealing property of on-load switch and outlet connecting portion to reducing the failure rate of distribution network, guarantee that the safe operation of electric power system is significant.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of on-load switch outlet black box is provided, to improve the degree of protection of on-load switch, guarantee the safe operation of electric power system.
Problem of the present invention is realized by following technical scheme:
A kind of on-load switch outlet black box, comprise the outlet current in the formation, the upper end of described outlet current connects post by the overlap joint fixed screw with the outlet of on-load switch and is connected, dock with the prefabricated connection-peg of outlet the lower end, the outer surface of outlet current 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, also leave overlap joint fixed screw installing hole on the prefabricated silicone rubber insulation layer, in the described overlap joint fixed screw installing hole silicone rubber seal plug is installed.
Above-mentioned on-load switch outlet black box, the bottom of described prefabricated silicone rubber insulation layer is equipped with the electrification in high voltage attention device, described electrification in high voltage attention device comprises electric capacity, current-limiting resistance and light-emitting diode, a termination outlet current after the three is connected in series, a termination ground wire.
Above-mentioned on-load switch outlet black box, overlap joint fixed screw installing hole interference fit on described silicone rubber seal plug and the prefabricated silicone rubber insulation layer, the inwall of described overlap joint fixed screw installing hole is provided with cannelure, and the sidewall of silicone rubber seal plug is provided with the annular protrusion that is complementary with the cannelure that overlaps on the fixed screw installing hole inwall.
The present invention utilizes prefabricated silicone rubber insulation layer and silicone rubber seal plug that the outlet current is sealed, outlet current and external environment are isolated, the class of insulation and the degree of protection of on-load switch have been improved, thoroughly eliminate the harmful effect of environmental factors such as humidity, temperature and filth to insulation property, guaranteed the safe operation of electric power system.The electrification in high voltage attention device can send the caution light signal when the outlet current is charged, remind the maintainer to take care.The present invention adopts the method for cast to make, and has realized the standardization of product, and modularization is convenient to processing and assembling.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is structural representation of the present invention;
Fig. 3 is connection diagram of the present invention;
Fig. 4 is the electrical schematic diagram of electrification in high voltage attention device.
Each list of reference numerals is among the figure: 1, bus; 2, silicone rubber seal plug; 3, on-load switch; 4, ring main unit in the distribution box; 5, outlet black box; 6, the prefabricated connection-peg of outlet; 7, seal boss; 8, overlap joint fixed screw; 9, prefabricated silicone rubber insulation layer; 10, outlet current; 11, annular protrusion; 12, electrification in high voltage attention device; C, electric capacity; R, current-limiting resistance; D, light-emitting diode.
Embodiment
Referring to Fig. 1～Fig. 3, traditional F LN36, ABB-SFG switchgear exist sealing property bad, easily advance dust, are subject to external environment influence, the shortcoming that the electric accident rate is high.The present invention includes outlet current 10, prefabricated silicone rubber insulation layer 9, silicone rubber seal plug 2, prefabricated silicone rubber insulation layer 9 and silicone rubber seal plug 2 connect post with the outlet of outlet current 10 and on-load switch and wrap up, prevent that extraneous moisture, dust and the filthy outlet that damages outlet current 10 and on-load switch from connecing post, electrification in high voltage attention device 12 reminds the 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 has fundamentally solved the sealing problem of the leading electricity part of on-load switch, make the IP degree of protection of product be promoted to IP67 by IP30, and have electrification in high voltage attention device 12 to do charged caution, and prevent charged misoperation, effectively ensured maintainer's operational security.And the present invention prepares electrification in high voltage attention device 12 in prefabricated silicone rubber insulation layer in advance, even do not connect power supply, and also can be because of wherein components and parts and line because of the former of high voltage induction thereby make diode displaying.
After the present invention used the sealing assembly, even flood takes place, on-load switch also can normally move at short notice, and can be adapted to the installation environment of high height above sea level.
