Abstract
The utility model relates to a maintenance tool for a transformer, and provides an auxiliary test tool for an oil and gas bushing transformer. The auxiliary test tool for the oil and gas bushing transformer is characterized by compressing an insulation shielding cover, a conductive hook, a high-voltage insulation cable and a terminal, wherein one end of the high-voltage insulation cable is electrically connected with the conductive hook, and the other end of the high-voltage insulation cable is electrically connected with the terminal; and the insulation shielding cover is sleeved on the high-voltage insulation cable which is located at one end of the conductive hook. When at use, the conductive hook hooks the bushing of the oil and gas bushing transformer through the check hole of a sulfur-hexafluoride enclosed-type assembled switch gear; the insulation shielding cover sleeved on the high-voltage insulation cable moves to the conductive hook to play the role of insulation and shielding; the terminal is electrically connected with a test instrument, and when the test is carried out, the test instrument is started for carrying out the test, such that the demands of conventional test items for oil and gas bushing transformer on-site maintenance can be met, and the auxiliary test tool for the oil and gas bushing transformer has the advantages of security and reliability, convenient carrying, high maintenance efficiency and the like.
Description
Technical field
The utility model relates to the Repair of Transformer instrument, specifically, is a kind of oil-gas casing transformer ancillary test instrument of using for the oil-gas casing Repair of Transformer.
Background technology
Sulfur hexafluoride sealed combination electrical equipment is widely used in the electric power system, prior art takes directly bushing shell for transformer to be packaged in the connected mode in the sulfur hexafluoride sealed combination electrical equipment, because bushing shell for transformer and sulfur hexafluoride sealed combination electrical equipment shell spacing are little, need bushing shell for transformer encapsulation tank body when carrying out Repair of Transformer, maintenance workload is large, and overhaul efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the shortcoming of prior art, provide a kind of easy to carry, overhaul efficiency is high, is used for the oil-gas casing transformer ancillary test instrument that the oil-gas casing Repair of Transformer is used.
The scheme that solves its technical problem employing is: a kind of oil-gas casing transformer ancillary test instrument, it is characterized in that: it comprises insulation shielding cover, conductive hook, high voltage insulation cable and terminal, one end of described high voltage insulation cable is electrically connected with conductive hook, the other end of high voltage insulation cable is electrically connected with terminal, is nested with the insulation shielding cover at the high voltage insulation cable that is positioned at conductive hook one end.
The utility model oil-gas casing transformer ancillary test instrument, conductive hook is hooked the sleeve pipe of oil-gas casing transformer during use by the inspection opening of sulfur hexafluoride sealed combination electrical equipment, being placed on insulation shielding cover on the high voltage insulation cable moves to the conductive hook place and plays the insulation shielding effect, terminal is electrically connected with test apparatus, during test, the firing test instrument can be tested, can satisfy the needs that the oil-gas casing transformer field overhauls every routine test project, have safe and reliable, easy to carry, the overhaul efficiency advantages of higher.
Description of drawings
Fig. 1 is that oil-gas casing transformer ancillary test instrument master looks schematic diagram;
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure: 1 terminal, 2 high voltage insulation cables, 3 conductive hook, 4 insulation shielding covers.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, oil-gas casing transformer ancillary test instrument of the present utility model comprises high voltage insulation cable 2, conductive hook 3, insulation shielding cover 4 and terminal 1.One end of described high voltage insulation cable 2 is electrically connected with conductive hook 3, and the other end of high voltage insulation cable 2 is electrically connected with terminal 1, is nested with insulation shielding cover 4 at the high voltage insulation cable 2 that is positioned at conductive hook 3 one ends.
When oil-gas casing transformer ancillary test instrument of the present utility model used: hook 3 inspection openings by sulfur hexafluoride sealed combination electrical equipment hooked the sleeve pipe of oil-gas casing transformer, be placed on insulation shielding cover radome 4 on the high voltage insulation cable 2 and move to conductive hook 3 places and play the insulation shielding effect, terminal 1 is electrically connected with test apparatus.During test, the firing test instrument can be tested.
