Description
Technical field
The utility model relates to a kind of ground lead structure for large-sized transformer core, belongs to transformer equipment technical field.
Background technology
In the structure of large-scale power transformer, unshakable in one's determination draw by the grounding sleeve on case lid, and cause fuel tank bottom by ground lead and be connected with ground plate, reach the object that makes iron core grounding.Ground lead is a copper bar integral manufacturing traditionally, and the hole of opening some quantity on copper bar, is fixed on fuel tank by bolt and insulator.But because fuel tank exists the factors such as the distance of highly inconsistent, copper bar and fuel tank is inconsistent, easily cause copper bar size long, processed complex, transportation and fitting operation inconvenience.
Utility model content
The utility model object is to provide a kind of ground lead structure for large-sized transformer core, the grounding copper bar of ground lead structure disconnects to be made, be divided into two parts, every section of copper bar length, bending are reduced, be convenient to processing, transportation, grounding copper bar is fixedly clamped by supporting insulator, can effectively avoid, because making the assembling difficulty that causes of tolerance, solving the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of ground lead structure for large-sized transformer core, comprise supporting insulator, grounding copper bar one, grounding copper bar two and grounding sleeve, described grounding copper bar one, grounding copper bar two clamps and is connected mutually with supporting insulator, being fixedly installed on fuel tank by supporting insulator strengthens in the outer limit of iron, between grounding copper bar one and grounding copper bar two, be connected to each other by lug plate and securing member, grounding sleeve comprises iron core grounding sleeve pipe and folder grounding sleeve, grounding copper bar two comprises iron core grounding copper bar and folder grounding copper bar, respectively with corresponding iron core grounding sleeve pipe, folder grounding sleeve is connected to each other.
Described supporting insulator comprises screw, pressing plate, insulator, holder, bolt and packing ring, grounding copper bar one or grounding copper bar two are arranged between pressing plate and holder, one end of insulator is clamped pressing plate to be connected with holder by screw, and the other end is strengthened the outer limit of iron by bolt and packing ring and fuel tank and is fixedly connected with.
Described securing member comprises brass bolt, copper nut, copper washer one, brass screw and copper washer two.
The beneficial effects of the utility model are: grounding copper bar disconnects to be made, the corresponding general part of grounding copper bar one for being made into for the different distance of copper bar and fuel tank, improve the standardization level of transformer, also make grounding copper bar two length shorten simultaneously, bending reduces, and is convenient to processing, the transportation of copper bar; The fixed form of supporting insulator and copper bar is the structure being fixedly clamped, and copper bar is located without perforate, has avoided the installation difficulty causing because making tolerance.
