500kV arresters are one of important electrical equipments of power system, when Lightning Over-voltage or operation occurs in power network
During overvoltage, its safe operation to power system plays a very important role.In order that arrester is in power system security
Reliability service to arrester, it is necessary to carry out preventive trial, including measurement DC reference voltage and the 0.75 times of direct current of having a power failure
Leakage current pilot project under reference voltage.But at the scene in test process, due to what is installed on induced electricity, grading ring and wire
Leaked electricity under the influence of the factors such as the position of ground wire, on-the-spot test D.C. reference voltage of arrester and 0.75 times of DC reference voltage
Stream, often occurs that test data is exceeded, therefore to install bare copper wire in sleeve pipe upper and lower side and be shielded or in pressurized line installing
Insulating cord, by drawing pressurized line with sleeve pipe angle into 90, so that test data is normal, but this brings pole to on-site maintenance
Big inconvenience.Therefore, the experience and historical data that on-the-spot test at present is substantially by testing crew are judged, without one
Individual reliable test connection device is in 90 ° to solve the problems, such as test of lightning arrester shielding and pressurized line and arrester.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the existing mode of connection, there is provided one kind is set using arrester self structure
Meter, easy to operate, safe and reliable 500kV Zinc-Oxide Arrester anti-interference test terminations.
The purpose of this utility model is achieved through the following technical solutions：
A kind of 500kV Zinc-Oxide Arresters anti-interference test termination, includes support, Zinc-Oxide Arrester, one end
The insulating bar laterally set with installation screw, two be embedded with scalable copper wire and both ends pass through latch connection formed elasticity
Shading ring；The Zinc-Oxide Arrester is placed on support, and two elastic shading rings are respectively fitted over Zinc-Oxide Arrester upper and lower two
Save on the upper and lower metal connecting piece between bushing porcelain vase, drawn from scalable copper wire and be circumscribed with shielding binding clip；It is provided with
Two panels outer end is connected to the connection copper sheet on two elastic shading rings, level of the inner with bending of two panels connection copper sheet
Connection joining seam simultaneously mutually overlaps, and the one end of lateral isolation bar with installation screw is installed on connection joining seam by adjusting trip bolt
On, insulating bar is mutually perpendicular to arrester bushing；At least two V-arrangement locator cards, front end are welded with insulating bar top surface
High-potting pressurized line with high-voltage connecting wire clamp, which is horizontal, to be placed in V-arrangement locator card, and high-voltage connecting wire clamp is clipped in metal company
On fitting, it is 90 ° to make pressurized line and arrester bushing porcelain vase angle；Pressurization line back end be linked in sequence DC generator, survey
Trial signal connecting line and control cabinet.
The utility model utilizes the structure of arrester itself, and is substituted using the shading ring be easy to latch and opened existing
Bare copper wire set, by connect copper sheet connect insulating bar, make insulating bar vertical with the bushing porcelain vase of arrester, by high pressure
The pressurized line of experiment is lain on insulating bar, and the angle realized between pressurized line and bushing porcelain vase is in 90 °, is met lightning-arrest
The requirement of device high-potting operational procedure.Using the utility model, tester carries out sleeve pipe winding without using bare copper wire and come
Shielded, drawn without using insulation pull rope so that pressurized line and sleeve pipe angle are in 90 °, avoid pressurized line angle not
The time that sufficient and repeated multiple times wiring wastes, improve test efficiency.
