Abstract
A load switch bus sealing assembly belongs to the technical field of switches. The technical proposal is that the load switch bus sealing assembly comprises a bus current-carrying conductor, a silicon rubber connecting sleeve and a bus sealing sleeve, wherein the silicon rubber connecting sleeve is in a cylindrical shape, the bottom of the silicon rubber connecting sleeve is sleeved on a bus connection pole of a load switch, a bus through hole is arranged on the side wall of the silicon rubber connecting sleeve, the end of the bus current-carrying conductor is threaded into the silicon rubber connecting sleeve through the bus through hole and fixedly connected with the bus connection pole by a lap fixation screw, a silicon rubber sealing plug is arranged on the upper end of the silicon rubber connecting sleeve, the bus sealing sleeve is sleeved on the outer part of the bus current-carrying conductor, and the end of the bus sealing sleeve is arranged in the bus through hole on the side wall of the silicon rubber connecting sleeve. The bus is sealed by the silicon rubber connecting sleeve and the bus sealing sleeve, thus the bus 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 bus seal assembly 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 bus 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 bus 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 bus seal assembly 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 bus seal assembly, comprise the bus current－carrying conductor in the formation, silicon rubber adapter sleeve and bus sealing shroud, described silicon rubber adapter sleeve is tubular, the bus that its lower end is enclosed within on-load switch connects on the post, be provided with the bus via hole on the sidewall, the end of described bus current－carrying conductor penetrates in the silicon rubber adapter sleeve and connects post by the overlap joint fixed screw with bus from the bus via hole and is fixedly connected with, the upper end of silicon rubber adapter sleeve is provided with the silicone rubber seal plug, it is outside that described bus sealing shroud is enclosed within the bus current－carrying conductor, and its end is positioned at the bus via hole on the silicon rubber adapter sleeve sidewall.
Above-mentioned on-load switch bus seal assembly, described silicone rubber seal plug and silicon rubber adapter sleeve interference fit, be provided with cannelure on the inwall of described silicon rubber adapter sleeve upper end, the sidewall of silicone rubber seal plug be provided with silicon rubber adapter sleeve inwall on the annular protrusion that is complementary of cannelure.
Above-mentioned on-load switch bus seal assembly, the bus via hole interference fit on described bus sealing shroud and the silicon rubber adapter sleeve sidewall.
The utility model utilizes silicon rubber adapter sleeve and bus sealing shroud that bus is sealed, with bus current－carrying conductor and external environment isolation, 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. 2 is the structural representation of bus current－carrying conductor and bus sealing shroud;
Fig. 3 is the structural representation of silicon rubber adapter sleeve;
Fig. 4 is connection diagram of the present utility model.
Each label is among the figure: 1, bus sealing shroud; 2, silicon rubber adapter sleeve; 3, on-load switch; 4, distribution box; 5, outlet; 6, connection-peg; 7, bus current－carrying conductor; 8, silicone rubber seal plug; 9, overlap joint fixed screw; 10, annular protrusion; 11, bus seal assembly.
Embodiment
Referring to Fig. 1～Fig. 4, the utility model comprises bus current－carrying conductor 7, bus sealing shroud 1, silicon rubber adapter sleeve 2 and silicone rubber seal plug 8, bus sealing shroud 1, silicon rubber adapter sleeve 2 and silicone rubber seal plug 8 connect post with the bus of bus current－carrying conductor 7 and on-load switch and wrap up, and prevent that extraneous moisture, dust and the filthy bus that damages bus current－carrying conductor 7 and on-load switch from connecing post.
The utility model utilizes local coating technology with the isolation of bus and external environment, and assembly adopts the form of standard cell combination, utilizes the compression seal characteristic of silicon rubber, the silicon rubber pre-constructed unit is connected with bus and seals.
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.
