Abstract
The utility model discloses a gas isolation load switch casing and a load switch employing the casing, in particular, the casing includes a housing (1), a transparent cover (2), fixed bolts (3) and an O-shaped seal ring (4); the housing (1) is provided with a ring seal groove (5) on its end face, the O-shaped seal ring (4) is embedded in the ring seal groove (5), and the transparent cover (2) is connected with the housing (1) through the fixed bolts (3) in a seal manner. By means of embodiment of the utility model, sealing property of the load switch casing is improved, and a cover of the load switch casing is transparentized, thereby operators can view inner structure and operation situation of the load switch easily.
Description
Technical field
The utility model relates to the electric power system field, relates in particular to a kind of gas-insulated on-load switch shell and uses the on-load switch of this shell.
Background technology
In electric power system, power distribution network plays the important function of distributing electric energy, and on-load switch is the important switchgear that makes up power distribution network.So-called on-load switch is meant and can closes in overload condition ShiShimonoseki of normal galvanic circle conditioned disjunction regulation, carrying and drop-out current, also can be under unusual galvanic circle condition (for example short circuit) in accordance with regulations the switchgear of time loaded current; It is a kind of switchgear between circuit breaker and isolating switch, can cut off rated load electric current and certain overload current, also can carry the short circuit current of stipulated time, but can not cutting-off of short-circuit electric current, many and high-tension fuse is used, by high-tension fuse cutting-off of short-circuit electric current; It has simple arc-control device, closes, cut-offs in the pass in the process of load current, and extinguish arcs prevents device damage rapidly.
At present, in existing power distribution network, there are various forms of on-load switches, distinguish according to the arc quenching principle that is adopted and to comprise SF6 gas load switch and vacuum load switch; So-called SF6 gas load switch is exactly the SF6 gas of sealing certain pressure in the on-load switch shell, thereby reaches the purpose of on-load switch insulation and arc extinguishing; So-called vacuum load switch is exactly that the gas in the on-load switch shell is extracted out, thereby forms an enclosed vacuum space, to reach the purpose of on-load switch insulation and arc extinguishing; Apparently, the sealability of on-load switch shell directly determines the insulation property and the arc extinction performance of these two kinds of on-load switches.Existing on-load switch shell comprises housing and cap, and described housing closely is connected by bolt with cap, and described cap is provided with seal groove, can promote the sealing property between housing and cap, and described cap is provided with charge valve.
In the technique scheme, there are the following problems at least:
The first, the housing and the cap of existing on-load switch shell are opaque material, in on-load switch divide-shut brake and running, can't observe the divide-shut brake situation and the operation conditions of on-load switch; For example, the SF6 gas load switch of a kind of collection of ubiquity three stations on the market (promptly close close, isolation, ground connection three stations) one, because its housing and cap have all adopted opaque material, so can't observe the change of the inner station of on-load switch, this can bring very big inconvenience in the installation and maintenance process.
The second, existing on-load switch shell will be located on the cap the seal groove that housing and cap play important sealing function, because the limitation of existing cap forming technique, the end face evenness of its set seal groove is relatively poor, influences sealing property to a certain extent.
Three, existing on-load switch shell has been located at charge valve on the cap, because the limitation of existing cap forming technique, the end face evenness of the air-filled pore of installation charge valve is also relatively poor, also influences sealing property to a certain extent.
Summary of the invention
The purpose of this utility model provides a kind of gas-insulated on-load switch shell and uses the on-load switch of this shell, so that improve on-load switch body seal performance, and realized the transparence of on-load switch shell cap, to make things convenient for the staff on-load switch internal structure and operation conditions are observed.
The purpose of this utility model is achieved through the following technical solutions:
A kind of gas-insulated on-load switch shell comprises: housing 1, translucent cover 2, set bolt 3 and O RunddichtringO 4;
The end face of described housing 1 is provided with annular seal groove 5, and O RunddichtringO 4 is embedded in the annular seal groove 5, and translucent cover 2 is connected with housing 1 by set bolt 3 and seals.
Preferably, this device also comprises charge valve, and described charge valve is located on the housing 1.
Preferably, the material of corresponding translucent cover 2 is a Merlon.
Preferably, the material of corresponding housing 1 is an epoxy resin.
Preferably, be evenly equipped with fixing hole on the corresponding housing 1, also be provided with fixing hole on the correspondence position of described translucent cover 2, described set bolt 3 is connected translucent cover 2 by fixing hole and seals with housing 1.
Preferably, the number of fixing hole is 8 on the corresponding housing 1, and the number of fixing hole is 8 on the described translucent cover 2, and the number of described set bolt 3 is 8.
A kind of on-load switch, described on-load switch have adopted the gas-insulated on-load switch shell described in the technique scheme.
The technical scheme that is provided by above-mentioned the utility model as can be seen, gas-insulated on-load switch shell that the utility model embodiment provides and the on-load switch of using this shell have improved the sealing property of on-load switch shell by seal groove and charge valve being arranged on the housing 1 of on-load switch shell; Realize the transparence of on-load switch shell cap by cap being made translucent cover 2, thereby made things convenient for the staff that on-load switch internal structure and operation conditions are observed.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
