Description

An upper water tank for buried transformers

technical field

The utility model relates to an upper opening water tank of an underground transformer.

Background technique

The buried transformer is installed in the basement or cellar, which can advocate green power and optimize the urban environment. It is suitable for streets, highways, bridges, tunnels, parking lots, and is suitable for lighting and power systems in urban environments, airports, ports, tourist attractions, etc., especially Suitable for densely populated central cities. The buried transformer is divided into two parts above ground and underground, and its body is installed in a pit constructed of concrete without occupying surface space. The cover of the buried transformer is equipped with high-voltage casing and low-voltage terminals, high-voltage load switch and backup fuse, plug-in lightning arrester, pressure relief valve, vacuum pressure gauge, temperature control and oil level indicator. These accessories can be found in Observe and operate on the ground. The oil tank is made of stainless steel, with a fully sealed structure and a closed welded structure along the tank to minimize the sealing area, and can operate safely for a long time in the special environment in the ground.

The upper end of the pit of the buried transformer is usually composed of two side-opening flip covers. There will be gaps at the joints of the two flip covers, so it is inevitable that rainwater will flow into the pit through the gaps in rainy days, resulting in water accumulation inside the pit, which will damage the transformer. Insulation causes trouble.

Contents of the invention

The purpose of this utility model is to overcome the defects of the prior art, and provide an upper mouth water tank for buried transformers, which can resist rainwater from entering the pit from the butt joint of two flip covers, and effectively improve the internal water accumulation in the pit , which provides favorable conditions for the safe and reliable operation of buried transformers.

The technical solution to achieve the above purpose is: an upper water tank for a buried transformer, the buried transformer includes a rectangular cubic pit with the upper part exposed to the ground and an upper end open, a transformer installed in the pit, and a The above-ground part of the upper end of the pit, the above-ground part includes a ventilation window and a cover plate, and the ventilation window includes a window installed on the outer side of the wall on the upper end of the pit, the window consists of front and rear side frames and The left and right frames are surrounded; the cover plate includes a left flip cover whose left end is hinged on the upper end of the left frame and a right flip cover whose right end is hinged on the upper end of the right frame; The butt joints when the left and right flaps are closed are bridged between the center of the upper inner surface of the front side frame and the center of the upper inner surface of the rear side frame through a connecting piece, and the upper opening is connected to the bottom surface of the water tank. A drain pipe leading to the exterior of the rear side frame.

The upper water connection tank of the above-mentioned buried transformer, wherein, the upper water connection tank is made of stainless steel.

The water tank at the upper opening of the buried transformer of the utility model can resist rainwater from entering the pit from the butt joint of the two flaps, effectively avoid water accumulation inside the pit, and can also be used as a vertical support for the left and right flaps, It provides favorable conditions for the safe and reliable operation of the buried transformer.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to FIG. 1 , the buried transformer includes a rectangular cube pit 10 with the upper part exposed to the ground and an upper end open, a transformer installed in the pit 10 and an aboveground part located at the upper end of the pit 10 . The above-ground part includes ventilation windows and covers. The ventilation window includes a window 2 installed on the outer wall of the upper surface of the pit 10, and the window 2 is surrounded by front and rear side frames 21, 22 and left and right side frames 23, 24; It includes a left flip cover 31 whose left end is hinged on the upper end of the left side frame 23 and a right flip cover 32 whose right end is hinged on the upper end of the right side frame 24 .

Referring to Fig. 2 again, the upper mouth water tank 5 of the buried transformer of the present utility model is bridged between the center of the upper inner surface of the front side frame 21 and the center of the upper inner surface of the rear side frame 22 by a connector 50 This position corresponds to the butt joint gap when the left and right flaps 31, 32 are closed, so that the rainwater flowing down from the butt joint gap can flow in the water receiving tank 5, and the bottom surface of the upper opening water receiving tank 5 is connected to the rear side The outer drain pipe 6 of the frame 24 is used to discharge the accumulated water in the upper water receiving tank 5 without overflowing into the ground pit 10 .

Please refer to Fig. 2 again, connector 50 comprises a groove-shaped part and two mounting pieces respectively connected to the rear ends of both sides of the groove-shaped part with a width adapted to the width of the upper mouth water tank 5, and two mounting pieces are respectively provided with three mounting holes.

When installing the top water tank 5 of the buried transformer of the present utility model, first fix the two connectors 50 on the upper inner side surface of the front side frame 21 and the upper inner side surface of the rear side frame 22 respectively by screws, Then only need to put the two ends of the upper mouth water tank 5 on the grooved part of the connecting part 50 and get final product. When the transformer in the ground pit 10 needs to be hoisted in and out, do not just can take out the catch tank 5 easily with any tool. The catch water tank 5 adopts stainless steel to make, can also be used as the longitudinal support file of left and right flip cover 31,32.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
