Abstract

The utility model provides a gas detecting structure of a three-phase shunt reactor. In order to enable gas generated inside a container (2) of the three-phase shunt reactor not to stay inside the container and to be rapidly guided into a gas relay (5), the upper portion of the container (2) is inclined oppositely to ground; and a piping (4) used for an oil storage cabinet is arranged at the highest position of the upper portion of the container (2). Besides, the piping (4) is directly welded on a sleeve bag flange (7) of a sleeve bag (3); a plurality of cluster portions for connecting clusters of hardware (8) are arranged on the piping (4) connected with the sleeve bags (3); the cluster portions are connected by the piping (4); the cluster portions slightly parallel to the upper surface of the container (2) and inclined oppositely to the ground are connected onto the piping (4) of the container (2); and the gas relay (5) is arranged between the oil storage cabinet (6) and the cluster portions.

Description

The gas of parallel three phase reactor detects structure

Technical field

The gas that the utility model relates to a kind of parallel three phase reactor detects structure.

Background technology

Comprise the parallel three phase reactor under the situation of interior shunt reactor, will produce gas in the inside of container sometimes,, detect unusually by being collected in the gas that produces in the container so between container and oil conservator, Buchholz relay is set in general continuous use.In the general shunt reactor, the mounting structure of the existing Buchholz relay that uses for example has by the open communique of Japanese Utility Model 1992-127617 number etc. disclosed.

In this structure,, being provided with on this pipe arrangement on the basis of part parallel to the ground, be connected, on the parallel position, this ground Buchholz relay being set with oil conservator from pipe arrangement is erect on parallel container upper vertical ground, ground.

But because of parallel above the container to ground; so the gas that produces in inside is trapped in above the internal tank easily; and; this relay of invar is arranged on the parallel pipe arrangement in ground; so the gas that internal tank is produced promptly imports to relatively difficulty of Bu Hehuo Wurz protection relay; its result, unusual sometimes detection is slower.

Particularly in that parallel three phase reactor neutral point is outside when connecting, subsidiary 6 sleeve pipes, its sleeve pipe bag of mounting also needs 6, and the gas that essential internal abnormality produces is not trapped in sleeve pipe bag inside, and the structure of inflow Buchholz relay.

The utility model content

The technical problem that solves

Problem to be solved in the utility model is that the inner gas that produces of parallel three phase reactor is promptly imported Buchholz relay.

Technical scheme

The design is on the parallel three phase reactor, makes container (2) top face tilt relatively, the highest point on this container (2) top, and risers is to the pipe arrangement (4) of oil conservator.

In addition, go up directly welding pipe arrangement (4) in the sleeve pipe bag flange portion (7) of sleeve pipe bag (3), the pipe arrangement (4) that connects each sleeve pipe bag (3) is provided with the portion of trooping of trooping with binding hardware (8), with this portion of trooping with pipe arrangement (4) UNICOM.And the pipe arrangement (4) that connects this portion of trooping is with container (2) top almost parallel and to ground inclination, also is connected with pipe arrangement (4) from container (2) erect.

Buchholz relay (5) is arranged on aforementioned trooping between portion and the aforementioned oil conservator (6).

Beneficial effect

Because of towards the pipe arrangement (4) of container (2) top and oil conservator (6) face tilt relatively,, be imported into Buchholz relay (5) by pipe arrangement (4) so be not trapped in inside at the gas of the inner generation of container (2).

Embodiment

Use accompanying drawing, the utility model is described.In the parallel three phase reactor, take in the device body (1) that iron core and coil etc. constitute in container (2) inside of Fig. 1 record, usually, container (2) inside is full of insulating oil.The top of container (2) is face tilt relatively, and the highest point risers on this container (2) top is to the pipe arrangement (4) of oil conservator (6).

On the sleeve pipe bag (3) among Fig. 1, pipe arrangement (4) is directly welded in going up in sleeve pipe bag flange portion (7) as shown in Figure 3, the pipe arrangement (4) that connects each sleeve pipe bag (3) connects with binding hardware (8) shown in Figure 4, and this forms the portion of trooping of the pipe arrangement (4) shown in the B of Fig. 2.

As shown in Figure 2, the portion of trooping of the pipe arrangement at three places (4), two places near by oil conservator (6) are the parts that connect four pipe arrangements (4), are the parts of three pipe arrangements of connection (4) from oil conservator (a 6) place farthest.

As shown in Figure 2, the portion of trooping at three places is by pipe arrangement (4) UNICOM, and, as shown in Figure 1, for almost parallel above the container (2), to ground inclination.

Buchholz relay (5) is arranged on above-mentioned trooping between portion and the oil conservator (6) as depicted in figs. 1 and 2.

Formation as above then takes place unusually at device body (1), and when producing gas, this gas is not trapped in inside, is transmitted to the top of the inclination of container (2), perhaps collects by the pipe arrangement (4) of the inclination of the above-mentioned portion's connection of trooping through sleeve pipe bag (3).Therefore, gas promptly can be imported Buchholz relay (5).Thus, can promptly detect device body (1) take place unusual.
