Description

A connection and fixing structure of a dry-type transformer and a protective cover

Technical field:

The utility model relates to a connection and fixing structure of a dry-type transformer and a protective cover.

Background technique:

The protective cover of the dry-type transformer is generally of the bell type. There is no connection between the protective cover and the transformer, and the relative position is not fixed. It is possible to damage the transformer or the protective cover due to collision during transportation, or place it at will when it is in place at the site, so that the distance between the transformer and the protective cover is too large on one side and too small, and the electrical safety distance cannot be reached. The service life of the transformer is greatly reduced.

Invention content:

The utility model provides a connection and fixing structure of a dry-type transformer and a protective cover in order to solve the problems existing in the above-mentioned prior art.

The technical scheme adopted by the utility model is as follows: a connection and fixing structure of a dry-type transformer and a protective cover, including a protective cover, a transformer, a screw rod and a fastening nut, the top of the transformer is provided with four through holes, four A set of through holes are located on both sides of the transformer, a screw rod is passed through each through hole, a fastening nut is threadedly connected to the top of each screw rod, and the screw rod is axially positioned on the transformer. The protective cover is sleeved on the transformer, the bottom end of the screw rod is penetrated on the protective cover, a fastening nut is threadedly connected to the bottom end of the screw rod, and the screw is axially positioned on the protective cover.

Further, a channel steel is arranged around the lower port of the protective cover, a through hole is arranged on the channel steel, and the bottom end of the screw rod is penetrated in the through hole of the channel steel.

Further, the screw rods are arranged obliquely.

The utility model has the following beneficial effects:

The utility model has the advantages of simple structure and convenient operation, so that the transformer and its casing can be connected together more effectively, which can avoid damage to the transformer or the protective casing during transportation or when it is in place on site, and at the same time ensures the transformer and the protective casing. safe distance from the shell.

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings.

1 to 3, a connection and fixing structure of a dry-type transformer and a protective cover of the present invention includes a protective cover 1, a transformer 2, a screw 3 and a fastening nut. The two clips on the top of the transformer 2 are both There are two through holes, and the two through holes on each clip are located on both sides of the clip, a screw 3 is penetrated in each through hole, and a screw is threaded on the top of each screw 3. Fix the nut and axially position the screw 3 on the transformer 2, the protective cover 1 is sleeved on the transformer 2, the bottom end of the screw 3 is worn on the protective cover 1, and the bottom end of the screw 3 is threadedly connected with a fastening The nut and the screw 3 are positioned axially on the protective housing 1 .

In order to facilitate the screw 3 to be worn on the protective cover 1, a channel steel 11 is provided around the lower port of the protective cover 1, a through hole is provided on the channel steel 11, and the bottom end of the screw 3 is penetrated through the channel steel. 11 in the through hole. Screw 3 inclined setting.

The utility model utilizes four screws to connect and fasten the through holes of the channel steel at the bottom of the protective cover to increase the connection and fastness of the transformer and the shell. The utility model makes the transformer and its casing more effectively connected together, can avoid damage to the transformer or the protective casing during transportation or on-site, and also ensures the safe distance between the transformer and the protective casing.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some improvements can be made without departing from the principles of the present invention, and these improvements should also be regarded as the present invention. The scope of protection of the utility model.
