Abstract
The utility model relates to a high-voltage test auxiliary device used for a 10kV oxide lightning arrester. The device comprises a test connecting rod and an insulating partition. The test connecting rod comprises a rod body and an end joint. The rod body comprises a middle insulating section and a conducting section used to externally connect with a test line. The end joint is provided with external threads connected with a conducting end of the lightning arrester. The center of the middle insulating section is provided with a conductor electrically connect the end joint with the conducting section. The center of the insulating partition is provided with a hole through which the rod body of the test connecting rod can pass. Since other components on a copper bar (or an aluminum bar) do need dismounting, the device is convenient and fast, and is safe and reliable, and has good practicality.
Description
Technical field
The utility model relates to a kind of high-potting servicing unit for 10kV Oxide Arrester.
Background technology
Enclosed switchgear, because floor area is little, compact to design, holds more functional unit with less space and is widely used.Closed while waiting 10kV Oxide Arrester in small space to carry out high-potting to being installed on such, need remove the electric conductor being connected with lightning arrester and keep apart, the passage of test lead and lightning arrester pressurized portion and around electric conductor also must keep suitable safe distance, conventionally can adopt insulation to cover the measures such as isolation and guarantee insulating requirements, but the application of the method has certain limitation, often need to determine according to the installation site of lightning arrester and surrounding space, the space, installation site of lightning arrester is open, the electric conductor that is connected to lightning arrester is easily removed and is convenient to and keeps apart and can meet insulating requirements with insulating material, adopt said method.But the on-the-spot installation site that often can encounter lightning arrester is that one end is directly connected on grounding body, the other end is directly connected on copper bar (or aluminium row), being equivalent to copper bar (or aluminium row) and grounding body is clamped on lightning arrester, this class lightning arrester is after first arrester ground end being fixed at first when mounted, when being installed, lightning arrester other end screw rod is passed copper bar (or aluminium row) to the upper default eyelet of copper bar (or aluminium row) simultaneously, with nut, fix again, therefore require testing crew must first remove copper bar (or aluminium row), and on copper bar (or aluminium row), conventionally can be connected to current transformer, grounding switch, the miscellaneous equipment facilities such as outlet cable, the workload of therefore removing copper bar (or aluminium row) is very large, or by the installation standing screw complete removal at lightning arrester two ends, lightning arrester is taken out to transfer on safe place and test, these two kinds of methods all will be brought very large workload to testing crew, so that cause test of lightning arrester work loaded down with trivial details, inefficiency.
Summary of the invention
In order to overcome 10kV Oxide Arrester in above-mentioned small space, test inconvenient problem, the utility model provides a kind of high-potting servicing unit for 10kV Oxide Arrester, has advantages of safe and reliable, convenient and swift, practical.
The utility model has adopted following technical scheme: comprise test connecting rod and insulating barrier; Described test connecting rod comprises the body of rod and end-fitting, the body of rod comprises intermediate insulation section and is used for the conductive segment of external p-wire, end-fitting has the external thread being connected with lightning arrester conducting end, has the electric conductor that end-fitting is electrically connected to conductive segment in the middle of intermediate insulation section; In the middle of described insulating barrier, have the through hole passing for the shank portion of test connecting rod.
Further, the body of rod is provided with overhang insulation section in conductive segment outside.
Further, the body of rod is right cylinder.
The beneficial effects of the utility model are: owing between copper bar (or aluminium row) and lightning arrester conducting end, insulating barrier being set, and the test connecting rod of employing and copper bar (or aluminium row) insulation is as the coupling arrangement with the external test clamp of lightning arrester, do not need to remove other electric elements on copper bar (or aluminium row), alleviated staff's workload, convenient and swift, practical.And test connecting rod is the insulating material of outer envelope with insulating barrier with copper bar (or the aluminium row) position contacting, and the situation of high-voltage discharge ground connection can not occur during high-potting, guarantees safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model test bar linkage structure schematic diagram.
Fig. 2 is the utility model insulating barrier structural representation.
Embodiment
As shown in Figure 1, test connecting rod comprises the body of rod 2 and end-fitting 21, and the body of rod 2 be right cylinder, the body of rod 2 comprises intermediate insulation section 22, be used for external p-wire conductive segment 23 and be located at the overhang insulation section 24 outside conductive segment.Before end-fitting 21 is located at the intermediate insulation section 22 of the body of rod, end-fitting 21 has the external thread being connected with lightning arrester conducting end; There is the electric conductor 221 that end-fitting 21 is electrically connected to conductive segment 23 centre of intermediate insulation section 22, the insulation course 222 that skin is made for insulating material.
In the middle of insulating barrier 1, have the through hole 11 passing for the body of rod 2 parts of test connecting rod.
The intermediate insulation section 22 of the body of rod 2, overhang insulation section 24 and insulating barrier 1 insulating material used is epoxy resin.
Before test, first remove nut, the screw rod of lightning arrester one end for being connected and fixed, it is disconnected with the copper bar being connected (or aluminium row), insulating barrier 1 is placed between copper bar (or aluminium row) and lightning arrester conducting position, then by the end-fitting 21 of test connecting rod penetrate copper bar (or aluminium row) upper eyelet and the through hole 11 on insulating barrier 1 of fixing lightning arrester is installed and is screwed in the eyelet of lightning arrester be fixed.Now, intermediate insulation section 22 parts of the body of rod 2, through copper bar (or aluminium row), are clamped in testing wire clamp on the conductive segment 23 of test connecting rod, then the high-potting of carrying out according to a conventional method Oxide Arrester.
