Background technology
On November 28th, 2005, ratified to issue DL/T976-2005 " live line tool, device and equipment preventive trial code " with reform committee member by People's Republic of China's national development. In this standard, propose, the test product of 220KV and following electric pressure should be able to be tested by short duration power frequency withstand voltage (taking without puncturing, generating heat as qualified without flashover and without obvious).
Utility model content
The utility model object is to provide a kind of voltage withstanding experiment device of simple in structure, livewire work that operating efficiency is high insulating cord.
Scheme of the present utility model is as follows: the voltage withstanding experiment device of insulating cord for livewire work, comprise support bar, base, bearing block, bearing mounting and testing jig, described base four overturning angles arrange lower end support set, and described support bar one end is socketed by lower end support set;
Described bearing mounting is made up of back-up block and a pair of upper end support set, and described a pair of upper end support set tilts to be welded on respectively two ends, back-up block bottom, and the described support bar other end is socketed by upper end support set;
Described bearing block is fixed on bearing mounting, and the main shaft being fixed on testing jig is fixed by bearing and bearing block, makes testing jig rotatable;
On described testing jig, be fixed with somely to connector, between connector, stainless steel tube can be set, be used as earth electrode or high-field electrode.
Further, described testing jig comprises a pair of epoxy resin board and main shaft, and main shaft passes respectively the epoxy resin board middle part be arrangeding in parallel and stretches out, and a pair of epoxy resin board is fixed.
Further, described connector comprises body, and body two ends arrange bolt hole, and body middle part arranges U-shaped protuberance; Body is fixed on testing jig by bolt passing through bolt hole; Stainless steel tube snaps in U-shaped protuberance.
Further, described support bar, testing jig, main shaft are made by insulating materials.
Further, described base bottom is provided with castor.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The voltage withstanding experiment device of insulating cord for livewire work, comprises support bar 1, base 2, bearing block 3, bearing mounting and testing jig 4, and base 2 four overturning angles arrange lower end support set 5, and support bar 1 one end is fixed by socket by lower end support set 5; Bearing mounting is made up of back-up block 6 and a pair of upper end support set 7, and a pair of upper end support set 7 tilts to be welded on respectively back-up block 6 two ends, bottom, and support bar 1 other end is fixed by socket by upper end support set 7; Bearing block 3 is fixed on bearing mounting, and the main shaft 7 being fixed on testing jig 4 is fixed by bearing and bearing block, makes testing jig 4 rotatable;
Testing jig of the present utility model comprises a pair of epoxy resin board 8 and main shaft 9, main shaft 9 passes respectively epoxy resin board 8 middle parts that be arranged in parallel and stretches out, some to connector 10 by being fixed with on a pair of epoxy resin board fixing test frame, between connector, stainless steel tube 11 can be set, be used as earth electrode or high-field electrode. Connector 10 comprises body, and body two ends arrange bolt hole 11, and body middle part arranges U-shaped protuberance 12; Body is fixed on testing jig by bolt passing through bolt hole; Stainless steel tube 11 snaps in U-shaped protuberance 12; On the termination of stainless steel tube and U-shaped protuberance, through hole is all set, can passes through hole by metal wire both are fixed.
Support bar of the present utility model, testing jig, main shaft are made by insulating materials; Base bottom is provided with castor, can move at any time.
The utility model, in the time of test, is only placed two stainless steel tubes on testing jig, be used as respectively earth electrode or high-field electrode, connects the output line of earth connection and external high pressure testing arrangement. According to the difference of test voltage, two stainless steel tubes are placed also difference of distance.
Although above detailed description of the invention of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that description contains yet, all should be within protection domain of the present utility model.
