Description
Technical field
The utility model belongs to transformer manufacture technology, has related to specifically the mounting structure of a kind of 500kV generator transformer 500kV sleeve pipe bottom wiring in fuel tank.
Background technology
For 500kV transformer, 500kV wears cable formula sleeve pipe and can directly be connected with lead-in wire, because 500kV electric pressure is higher, need to add in sleeve pipe voltage equalizing ball outside shielding measure (insulating cylinder is directly enclosed in sleeve pipe voltage equalizing ball outside) to reduce real work field intensity, thereby reduce the distance of sleeve pipe to each several part, closely reduce volume of transformer.If Chinese Patent Application No. is 2008200525940 to disclose a kind of novel 500kV casing tube coil outgoing device, according to the finite element method of ELAX-2D and the electric field situation respectively calculating, enclose certain moulding pulp insulation at 500kV sleeve pipe voltage equalizing ball outer surface, adding two-layer insulating paper cylinder, between insulating paper cylinder, place stay form oil clearance, employing be thin paper cylinder, small oil gap.
But the transformer that is bolt fastening structure for 500kV sleeve pipe bottom, transformer lead is connected in voltage equalizing ball and completes with sleeve pipe, and insulating cylinder can not be by all shieldings of 500kV lead-in wire, and this has just easily produced safety problem.Therefore, on market, be badly in need of a kind of safe and reliable wiring construction that is directed to the 500kV sleeve pipe of structure with bolts and design.
Summary of the invention
The purpose of this utility model is the deficiency existing for existing 500kV sleeve pipe bottom wiring construction, provides voltage equalizing ball in a kind of components and parts reasonable Arrangement simple in structure, safe and reliable, each, bushing oil not need additionally to wrap paper pulp to meet the 500kV sleeve pipe bottom wiring construction of insulation distance needs.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of 500kV sleeve pipe bottom wiring construction, is the mounting structure of 500kV generator transformer high-pressure section 500kV sleeve pipe bottom wiring in fuel tank, comprises insulating cylinder, lead wire insulation shielding cylinder and is arranged on binding post and the voltage equalizing ball of insulating cylinder inside; Described binding post is arranged on voltage equalizing ball inside; Insert in insulating cylinder one end of described lead wire insulation shielding cylinder, and the one end of entangling voltage equalizing ball; Described binding post is connected with the lead-in wire entering in voltage equalizing ball through lead wire insulation shielding cylinder by bolt fastener.
In the utility model, set up a lead wire insulation shielding cylinder, having solved insulating cylinder when 500kV sleeve pipe bottom is bolt fastening structure can not, by all defects of shielding of 500kV lead-in wire, make 500kV sleeve pipe bottom wiring construction more safe and reliable; And adopt above-mentioned wiring construction, voltage equalizing ball not to need to wrap separately paper pulp, also can meet the needs of insulation distance, for installation and the transport of product have brought facility.
Further illustrate, described lead wire insulation shielding cylinder be shaped as bowl of a pipe shape.
The installation steps of wiring construction of the present utility model:
Step 1: first with lead wire insulation shielding cylinder, 500kV lead-in wire is connected, be about to lead-in wire through lead wire insulation shielding cylinder;
Step 2: binding post and voltage equalizing ball are installed to 500kV sleeve pipe bottom;
Step 3: voltage equalizing ball is moved up, expose binding post, then going between to connect is connected with binding post bolt fastener by the lead-in wire in lead wire insulation shielding cylinder;
Step 4: complete after above-mentioned wiring, insulating cylinder is dropped on to lead wire insulation shielding cylinder outside, so far 500kV lead link structure completes.
Compared with prior art, the beneficial effect that the utility model possesses:
1. adopt wiring construction of the present utility model, the insulating cylinder of fuel tank, bushing, bushing and 500kV lead-in wire shielding cylinder are put and are able to reasonable Arrangement, the needs of easy-to-connect have been met, the needs of part voltage levels voltage equalizing ball to insulation distance in bushing oil are met again, make voltage equalizing ball not need to wrap separately paper pulp, easy-to-connect operates, can save manpower again, raises the efficiency, and ensure presentation quality, save the floor space of oil tank of transformer.
2. the utility model has been realized the maximization of fuel tank internal space utilization, makes again voltage equalizing ball in bushing oil not need additionally to wrap paper pulp simultaneously, meets the needs of insulation distance, for installation and the transport of product have brought facility.
3. owing to adopting rational lead wire insulation shielding cylinder (bowl of a pipe shape), can reduce the floor space of transformer, save transformer oil, thereby reduce the total amount of transformer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-binding post, 2-voltage equalizing ball, 3-insulating cylinder, 4-lead wire insulation shielding cylinder.
