Abstract
The utility model discloses a transformer grounding device, including transformer tank, wire, earth connection, its characterized in that: still the boss form ground connection that middle part on the transformer tank case lid was provided with the through -hole risees the seat including setting up, the terminal box and ground connection nut, the lid that set up on ground connection risees the seat close the cover on ground connection risees the seat, the wire pass through ground connection and rise the through -hole of seat and connect in the terminal box, the earth connection is connected on the ground connection nut, terminal box and ground connection nut between still be provided with the lead -out wire. The utility model has the beneficial effects of, this device simple structure has two protect function, has solved the situation that the grounding sleeve that exists in former iron core, the folder ground connection can not bear big pressure, and the installation maintain convenient.
Description
Technical field
The utility model relates to transformer manufacture technology, is specifically related to a kind of transformer grounding device.
Background technology
Existing transformer core, folder ground connection majority are for draw wire respectively from yoke on iron core and iron core upper clamping piece place, wire termination is connected on the grounding sleeve end being arranged on transformer tank tops, and grounding sleeve head end is connected the mode ground connection of induced current being introduced underground with copper bar.This kind of earthing mode needs to install two grounding sleeves at case lid top, the proof pressure of grounding sleeve is less, easily there is oil leakage phenomenon in the situation of bearing pressure larger at transformer, when transformer running environment (as underground substation) does not possess overall maintenance condition, this kind of situation cannot be remedied.
Utility model content
For the above-mentioned defect existed in prior art and deficiency, the utility model provides a kind of transformer grounding device.
The utility model is achieved by the following technical solution, a kind of transformer grounding device, comprise oil tank of transformer, wire, earth connection, it is characterized in that: also comprise the boss-shaped ground connection that the middle part be arranged on transformer oil tank cover is provided with through hole and raise seat, be arranged on ground connection and raise terminal box on seat and grounding nut, cover the cover raised ground connection on seat, the through hole that described wire raises seat by ground connection is connected in terminal box, earth connection is connected on grounding nut, is also provided with lead-out wire between described terminal box and grounding nut.
Described wire is at least two.
Usefulness of the present utility model is, this apparatus structure is simple, has two defencive function, solves the situation that the grounding sleeve existed in former iron core, folder ground connection can not bear large pressure, and convenient for installation and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that B-B of the present utility model is to zoomed-in view;
In figure, 1, wire, 2, terminal box, 3, lead-out wire, 4, grounding nut, 5, cover, 6, ground connection raises seat, 7, earth connection, 8, oil tank of transformer.
Embodiment
Below by indefiniteness embodiment and by reference to the accompanying drawings to utility model further instruction:
As shown in drawings, a kind of transformer grounding device, comprise oil tank of transformer 8, wire 1, earth connection 7, also comprise the boss-shaped ground connection that the middle part be arranged on oil tank of transformer 8 case lid is provided with through hole to raise seat 6, be arranged on ground connection and raise terminal box 2 on seat 6 and grounding nut 4, cover the cover 5 raised ground connection on seat, the through hole that described wire 1 raises seat by ground connection is connected in terminal box 2, earth connection 7 is connected on grounding nut 4, is also provided with lead-out wire between described terminal box 2 and grounding nut 4.
As specific embodiment, from transformer core, wire 1 is drawn at yoke and iron core upper clamping piece place respectively, raise seat 6 by the ground connection on oil tank of transformer 8 case lid to be again connected with terminal box 2 terminal, the lead-out wire 3 finally by terminal box 2 connects grounding nut 4 and iron core induced current is introduced underground.If there is terminal box 2 leakage scenarios in transformer long-play under larger pressure, without the need to changing any parts, only the lead-out wire 3 of terminal box 2 need be separately fixed at the grounding nut 4 on ground connection rising seat 6, be grounded function, then with cover 5, terminal box 2 being sealed in ground connection raises in seat 6, solves terminal box 2 leakage problems.
Claims (2)
1. a transformer grounding device, comprise oil tank of transformer, wire, earth connection, it is characterized in that: also comprise the boss-shaped ground connection that the middle part be arranged on transformer oil tank cover is provided with through hole and raise seat, be arranged on ground connection and raise terminal box on seat and grounding nut, cover the cover raised ground connection on seat, the through hole that described wire raises seat by ground connection is connected in terminal box, earth connection is connected on grounding nut, is also provided with lead-out wire between described terminal box and grounding nut.
2. transformer grounding device according to claim 1, is characterized in that: described wire is at least two.
