Abstract
A load switch inlet and outlet wire sealing assembly belongs to the technical field of switches. The technical scheme is that the sealing assembly comprises an outlet wire current-carrying conductor, wherein the upper end of the outlet wire current-carrying conductor is connected with an outlet wire connection pole of a load switch by a lap fixation screw, the lower end is butted with an outlet wire splicing head, an epoxy resin cast layer is arranged on the outer surface of the outlet wire current-carrying conductor, a sealing gasket is arranged on the butting surface of the epoxy resin cast layer and an epoxy resin shell of the load switch, a lap fixation screw mounting hole is arranged on the epoxy resin cast layer, and a silicon rubber sealing plug is mounted in the lap fixation screw mounting hole. The outlet wire current-carrying conductor is sealed by the epoxy resin cast layer and the silicon rubber sealing plug, thus the outlet wire current-carrying conductor is isolated from the external environment, the insulation level of the load switch is improved, and the adverse effects of environment factors such as humidity, temperature and pollution on the insulation performance are thoroughly eliminated, and the safe operation of a power supply system is ensured.
Description
Technical field
The utility model relates to a kind of outlet black box that can significantly improve FLN36 and SFG on-load switch degree of protection, belongs to the switching technique field.
Background technology
On-load switch is the vitals in the power distribution equipment, and the housing of on-load switch (such as FLN36) commonly used is general to be adopted reinforced epoxide resin vacuum to pour into a mould 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－carrying conductor, 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 subject to the impact of environmental factor 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 occurs 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.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of on-load switch line black box is provided, and to improve the degree of protection of on-load switch, guarantees the safe operation of electric power system.
Problem described in the utility model is realized by following technical scheme:
A kind of on-load switch line black box, comprise the outlet current－carrying conductor in the formation, the upper end of described outlet current－carrying conductor connects post by the overlap joint fixed screw with the outlet of on-load switch and is connected, dock with the outlet connection-peg lower end, outer surface at the outlet current－carrying conductor is provided with the poured with epoxy resin layer, be provided with seal washer on the interface of the epoxy package of described poured with epoxy resin layer and on-load switch, also leave overlap joint fixed screw installing hole on the poured with epoxy resin layer, in the described overlap joint fixed screw installing hole silicone rubber seal plug is installed.
Above-mentioned on-load switch line black box, overlap joint fixed screw installing hole interference fit on described silicone rubber seal plug and the poured with epoxy resin layer, be provided with cannelure on the inwall of described overlap joint fixed screw installing hole, be provided with the annular protrusion that is complementary with the cannelure that overlaps on the fixed screw installing hole inwall at the sidewall of silicone rubber seal plug.
The utility model utilizes poured with epoxy resin layer and silicone rubber seal plug that the outlet current－carrying conductor is sealed, make the isolation of outlet current－carrying conductor and external environment, improved the class of insulation of on-load switch, thoroughly eliminate the harmful effect of the environmental factors such as humidity, temperature and filth to insulation property, guaranteed the safe operation of electric power system.The utility model 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 utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is connection diagram of the present utility model.
Each label is among the figure: 1, bus; 2, silicone rubber seal plug; 3, on-load switch; 4, distribution box; 5, outlet black box; 6, outlet connection-peg; 7, seal washer; 8, overlap joint fixed screw; 9, poured with epoxy resin layer; 10, outlet current－carrying conductor; 11, annular protrusion.
Embodiment
Referring to Fig. 1～Fig. 3, traditional F LN36 switchgear exists sealing property bad, easily advances dust, is subject to external environment influence, the shortcoming that the electric accident rate is high.The utility model comprises outlet current－carrying conductor 10, poured with epoxy resin layer 9, silicone rubber seal plug 2 and seal washer 7, poured with epoxy resin layer 9 and silicone rubber seal plug 2 connect post with the outlet of outlet current－carrying conductor 10 and on-load switch and wrap up, and prevent that extraneous moisture, dust and the filthy outlet that damages outlet current－carrying conductor 10 and on-load switch from connecing post.
The utility model is the European plugs of poured with epoxy resin, and poured with epoxy resin layer 9 fitted seal packing ring 7 are finished the sealed insulation of outlet current－carrying conductor, 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, makes the IP degree of protection of product be promoted to IP67 by IP30.After using the sealing assembly, even flood occurs, on-load switch also can normally move at short notice, and can be adapted to the installation environment of high height above sea level.
