Abstract
A cable incoming device of transformer high-voltage side solves the problems that presently high voltage sides of 66 kV transformers in electric power system are usually led out by oil-air condenser bushings, transformers are arranged high and are not easy to go deeply into loading center, and high frames for transformer room have high cost and waste land resource. The cable incoming device of transformer high-voltage side comprises a transformer main oil tank equipped with a lateral port, and the lateral port is connected with a lifting seat through a flange which is provided with a condenser oil-oil separating casing. A leading-in terminal of the condenser oil-oil separating casing is connected with a high-voltage winding lead wire, and the top and the bottom of the lifting seat use flanges to respectively connect with a condenser casing and a cable plug head both for test which are connected with a leading-out terminal of the condenser oil-oil separating casing. Connection parts among the transformer main oil tank, the condenser casing and the cable plug head both for test and the lifting seat are provided with seal devices. The cable incoming device of transformer high-voltage side has advantages of small occupation area, space-saving property, loading center accessibility, convenient assembly and maintenance, good craftiness, beautiful appearance and easy operation.
Description
Technical field
The utility model relates to a kind of transformer high-voltage side long cable section of ingoing line device that is applied to power transmission and transformation system.
Background technology
Electric power system 66KV transformer high-voltage side adopts oil-air capacitance graded bushing to draw more at present, and transformer integral body is very high, should not go deep into load center, and room, transformer room frame is very high, cost height, waste land resource.
Summary of the invention:
The purpose of this utility model will solve the problems referred to above that prior art exists, and provides a kind of easy for installation, is convenient to go deep into the transformer high-voltage side long cable section of ingoing line device of load center.
The utility model is achieved in that it is provided with the side mouth on the transformer main fuel tank, on the side mouth, be connected with the seat that raises by flange, on flange, be provided with condenser type oil-oily disrance sleeve, condenser type oil-oily disrance sleeve end of incoming cables is connected with the high pressure winding leads, seat top and bottom are connected with test condenser-type terminal and cable connect-disconnect plug respectively by flange raising, test is connected with condenser type oil-oily disrance sleeve leading-out terminal respectively with the cable connect-disconnect plug with condenser-type terminal, at oil tank of transformer, test is provided with sealing device with the junction of condenser-type terminal and the cable plug and the seat that raises.
The utlity model has following advantage:
1, floor space is little, conserve space
Transformer main fuel tank inner high voltage winding leads leads to the outside seat that raises through condenser type oil-oily disrance sleeve, compare with conventional condenser oil-casing air, owing to can adopt side inlet wire mode, reduce whole transformer overall dimensions, save construction area and space, improve land utilization ratio, remarkable in economical benefits.
2, can go deep into load center
Owing to adopt and can pull out formula cable connect-disconnect plug, reduce the safe distance of people and electrified body, be suitable for and go deep into the load center power supply, shorten and send electrical distance, reduce line loss.
3, installation, easy to maintenance
Because the main fuel tank transformer oil is isolated mutually with the interior transformer oil of the seat that raises, and need not bleed off transformer oil in the main fuel tank during installation, installation workload is little, saves the set-up time, increases work efficiency.No matter interior still this line leading device of main transformer goes wrong, and deals with separately, is independent of each other.When transformer is tested, condenser type oil-tubing and casing is connected with capacitance graded bushing with test, after test is finished, will tests capacitance graded bushing and pull down with cable, good with cover plate and flange seal.When transformer is worked, use cable to be connected and get final product with the cable sleeve connect-disconnect plug.
4, good manufacturability
This installs good looking appearance, and good manufacturability is easy to operate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, on transformer main fuel tank 1, be provided with the side mouth, be connected with the seat 8 that raises at the side mouth by flange 3, on flange 3, be provided with condenser type oil-oily disrance sleeve 4, condenser type oil-oily disrance sleeve 4 ends of incoming cables are connected with high pressure winding leads 2, flange 6 is passed through in seat 8 tops and bottom raising, 10 are connected with test condenser-type terminal 5 and cable connect-disconnect plug 11 respectively, test is connected with condenser type oil-oily disrance sleeve 4 leading-out terminals respectively by cable 7 with cable connect-disconnect plug 11 with condenser-type terminal 5, connecting transformer main fuel tank 1 and the seat 8 that raises, test is used condenser-type terminal 5 and is raise the flange 3 of seat 8 and the cable plug 11 and the seat 8 that raises, 6 and 10 places are provided with seal gasket 12, as sealing device, guarantee that transformer main fuel tank 1 does not mix and the seat 8 seepage oil that prevent to raise with the seat 8 interior oil that raise.Transformer main fuel tank 1 inner high voltage winding leads 2 leads to outside rising seat 8 through condenser type oil-oily disrance sleeve 4, and transformer oil and transformer main fuel tank 1 interior transformer oil are isolated mutually by seal gasket in the seat 8 that raises.Fitting operation hand hole 9 on the seat 8 that raises, various connection work in the seat 8 of being convenient to raise.
