Abstract
The utility model relates to a transformer-earthing device, which belongs to a structural design for the earthing of the iron cores and clamps of a transformer. The transformer-earthing device comprises an oil tank-earthing wire and an earthing flange. The transformer-earthing device has the following characteristics: the lower section of an oil tank is provided with a cavity, in which the earthing flange is arranged, the earthing flange is provided with an epoxide resin terminal board, lead-out conductive rods are inserted in the epoxide resin terminal board, one end of each lead-out conductive rod is connected with the iron core-connecting wire and the clamp-earthing connecting wire of the transformer-earthing device, the other end of each lead-out conductive rod is connected with an earthing conductive rod through a short-circuiting sheet, and the earthing conductive rods are connected with the oil tank-earthing wire. Consequently, the utility model has the advantages of convenientconnection, simple structure, high reliability, low fabrication cost, stain resistance and the like.
Description
(1) technical field
The utility model relates to a kind of transformer grounding device, belongs to a kind of of transformer core, the design of folder ground connection.
(2) background technology
Present stage, the earthing mode of transformer core, folder is the top by fuel-economizing case on the transformer, and utilization grounding sleeve, ground connection copper bar and post insulator cause the lower oil tank place, thereby realizes the function of transformer core and folder reliable ground.Because the transformer type body is bigger, required ground connection copper bar is many, for this reason, makes the transformer manufacturing cost increase waste of raw materials.
(3) summary of the invention
The utility model provides a kind of cost low transformer grounding device in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of transformer grounding device, comprise lower oil tank, fuel tank earth connection, its special character is: establish a cavity on the described lower oil tank, be provided with the ground connection flange in the described cavity, described ground connection flange is provided with the epoxy resin terminal board, be plugged with on the described epoxy resin terminal board and draw conducting rod, a described end of drawing conducting rod is connected with the iron core connecting line and the folder ground connection connecting line of transformer grounding device, the other end of drawing conducting rod is by the short circuit sheet, be connected on the ground connection conducting rod, described ground connection conducting rod is connected on the fuel tank earth connection.
For safety and attractive in appearance, at epoxy resin terminal board peripheral hardware one protective cover.
Therefore, the utlity model has easy to connect, simple in structure, high reliability, low cost of manufacture, advantage such as anti-pollution.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks schematic diagram for the master of the utility model transformer grounding device.
Fig. 2 is the side cross-sectional schematic of the utility model transformer grounding device.
Fig. 3 is the schematic diagram of traditional transformer earthing device.
Fig. 4 is the schematic diagram of the utility model transformer grounding device.
Among the figure, 1 fuel tank earth connection, 2 draw conducting rod, 3 ground connection flanges, 4 epoxy resin terminal boards, 5 short circuit sheets, 6 ground connection conducting rods, 7 protective covers.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises lower oil tank, fuel tank earth connection 1, its key points in design is: establish a cavity on the described lower oil tank, be provided with ground connection flange 3 in the described cavity, described ground connection flange 3 is provided with epoxy resin terminal board 4, be plugged with on the described epoxy resin terminal board 4 and draw conducting rod 2, a described end of drawing conducting rod 2 is connected with the iron core connecting line and the folder ground connection connecting line of transformer grounding device, the described other end of drawing conducting rod 2 is connected on the ground connection conducting rod 6 by short circuit sheet 5, described ground connection conducting rod 6 is connected on the fuel tank earth connection 1, described epoxy resin terminal board 4 peripheral hardwares one protective cover 7.
The iron core of this device, folder ground connection connecting line and draw conducting rod 2 and reliably be connected utilize short circuit sheet 5 to be connected respectively to ground connection conducting rod 6 then, thereby realize the function of transformer core and folder reliable ground; This transformer grounding device is compared with traditional structure, has saved parts such as transformer grounding sleeve pipe, ground connection copper bar, post insulator, thereby has saved the installing space of transformer outside, and the transformer appearance design is rationalized more.This device is mainly used in the power transformer of 110kV and above electric pressure.That this transformer grounding device has is easy to connect, simple in structure, high reliability, characteristics such as anti-pollution, is the up-to-date substitute of traditional structural design.
