Description

Technical Field

[0001] The utility model relates to the field of transformer equipment, in particular to an installation structure for a gas relay gas collecting box of a transformer. Background Art

[0002] In the power system, a transformer is a key energy conversion device. To ensure the safe operation of the transformer, a gas relay is widely used to detect internal faults of the transformer. As an important part of the gas relay, the gas collecting box is responsible for collecting the gas generated during faults. The existing gas collecting box is installed on the terminal box of the transformer. Usually, a U-shaped mounting bracket is welded on the outer wall of the terminal box, and a mounting base plate is screwed on the back of the gas collecting box. The gas collecting box is fixed by screwing or welding the mounting base plate and the mounting bracket, so as to realize the installation of the gas collecting box. For such an installation structure, a mounting bracket needs to be welded on the terminal box for each installation of a gas collecting box. If the position of the gas collecting box needs to be adjusted due to installation errors, the mounting bracket can only be welded again, making the installation and disassembly of the gas collecting box very inconvenient, time-consuming, laborious and material-consuming. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an installation structure that is convenient for the installation and disassembly of the gas collecting box, is easy to use, and saves time, labor and materials in installation.

An installation structure for a gas relay gas collecting box of a transformer includes a mounting bracket fixedly connected to the terminal box of the transformer and a mounting base plate for mounting the gas collecting box. A vertically extending mounting vertical plate is detachably and fixedly connected to the mounting bracket, and the mounting base plate is screwed and fixed to the mounting vertical plate through a first bolt.

[0005] In this solution, by screwing the mounting base plate onto the mounting vertical plate, multiple mounting base plates can be installed on one mounting vertical plate, greatly reducing the usage amount of the mounting brackets and making the processing and manufacturing more convenient. When the position of the gas collecting box needs to be adjusted, there is no need to weld the mounting bracket again, making the installation and disassembly of the gas collecting box more convenient and saving time, labor and materials in the process.

[0006] As an optimization, multiple groups of first screw holes for screwing the first bolt are provided on the mounting vertical plate, and the multiple groups of first screw holes are arranged vertically.

One end of the two first vertical sides is fixedly connected to the side wall of the terminal box, the other ends of the two first vertical sides are connected through the first horizontal side, and a second screw hole for the second bolt to pass through is provided on the first horizontal side.

[0009] As an optimization, the reinforcing bracket and the mounting vertical plate are fixedly connected by a third bolt.

[0010] As an optimization, the cross-section of the reinforcing bracket includes two opposite second vertical sides, a second horizontal side, and two third horizontal sides. Both ends of the second horizontal side are fixedly connected to one end of the two second vertical sides. The other ends of the two first vertical sides are respectively fixedly connected to one end of the two third horizontal sides. The other ends of the two third horizontal sides are away from each other. A second screw hole for the second bolt to pass through is also provided on the second horizontal side, and a third screw hole for the third bolt to pass through is provided on the third horizontal side.

[0011] As an optimization, the mounting bottom plate includes a first rectangular portion and a second rectangular portion extending horizontally. A first screw hole for the first bolt to pass through is provided on the first rectangular portion. One end of the first rectangular portion extends to the outside of the terminal box and is fixedly connected to the second rectangular portion. A fourth screw hole for mounting the air collecting box is provided on the second rectangular portion.

[0012] As an optimization, the width of the first rectangular portion is half of the width of the second rectangular portion.

[0013] The beneficial effects of the present utility model are as follows: In this solution, the mounting bottom plate is screwed and installed on the mounting vertical plate, and multiple groups of first screw holes are reserved on the mounting vertical plate. Multiple mounting bottom plates can be installed on one mounting vertical plate, greatly reducing the usage amount of the mounting brackets and making the processing and manufacturing more convenient. When the position of the air collecting box needs to be adjusted, there is no need to re-weld the mounting brackets, making the disassembly and assembly of the mounting bottom plate more convenient, saving time, labor, and materials in the process. The connection strength between the mounting vertical plate and the mounting bracket is improved through the reinforcing bracket. The reinforcing bracket and the mounting bracket, as well as the reinforcing bracket and the mounting vertical plate, are all screwed, which is convenient for disassembly and assembly.
