Abstract

The utility model relates to the technical field of current transformers, particularly to a gas-insulated current transformer. The technical scheme of the gas-insulated current transformer is that the gas-insulated current transformer comprises a base, a casing pipe, a lead pipe, a primary conduit, a shielding cylinder, an outer casing and an explosion-proof disc, wherein the casing pipe is fixed on the base, the top of the casing pipe is connected with the outer casing, the primary conduit and the shielding cylinder are arranged inside the outer casing, the lead pipe is arranged inside the casing pipe, the bottom of the lead pipe is connected with the base, the top of the lead pipe is connected with the primary conduit, and the top of the outer casing is provided with the explosion-proof disc. The gas-insulated current transformer has the advantages of avoiding internal insulation flashover during the operation of the gas-insulated current transformer, guaranteeing the normal working of circuits and the safe and reliable operation of products and grid systems.

Description

A kind of gas insulated high voltage current transformer
Technical field
The utility model relates to the current transformer technical field, particularly a kind of gas insulated high voltage current transformer.
Background technology
Along with the enforcement of the strong intelligent grid plan of State Grid Corporation of China, transformer station will develop to intelligent substation, and primary equipment will upgrade to intelligent power equipment, and secondary device then becomes intelligent control unit, and this is a revolutionary variation.For products such as transformer, instrument transformers, will make the transition to the intelligentized self-diagnostic function of representative.At present, need to be equipped with Insulated Current Transformers in the 500 kV transformer stations, insulation flashover in Insulated Current Transformers is in operation and takes place in succession, cause fault, the gas insulated high voltage current transformer erecting bed, due to limited conditions, generally all can't carry out the test of product partial discharge quantity, therefore the safe and reliable operation to product and network system affects.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of gas insulated high voltage current transformer is provided.
Its technical scheme is: comprise base, sleeve pipe, fairlead, conduit, shielding cylinder, shell, burst disk, sleeve pipe is fixed on the base, the sleeve pipe top connects shell, be provided with conduit and shielding cylinder in the shell, described inside pipe casing is provided with fairlead, the bottom of fairlead connects base, and the top of fairlead connects a conduit, and the top of shell is provided with burst disk.
Be provided with the high-tension shielding cover between described fairlead and the sleeve pipe.
The outside of described sleeve pipe is provided with the silica gel sheath.
The beneficial effects of the utility model are: avoid Insulated Current Transformers to be in operation interior insulation flashover takes place, guarantee the circuit operate as normal, guarantee the safe and reliable operation of product and network system.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the last figure: base 1, sleeve pipe 2, high-tension shielding cover 3, fairlead 4, conduit 5, shielding cylinder 6, shell 7, burst disk 8, silica gel sheath 9.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
A kind of gas insulated high voltage current transformer, comprise base 1, sleeve pipe 2, high-tension shielding cover 3, fairlead 4, conduit 5, shielding cylinder 6, shell 7, burst disk 8, sleeve pipe 2 is fixed on the base 1, sleeve pipe 2 tops connect shell 7, be provided with conduit 5 and shielding cylinder 6 in the shell 7, described sleeve pipe 2 inside are provided with fairlead 4, and the bottom of fairlead 4 connects base 1, the top of fairlead 4 connects a conduit 5, and the top of shell 7 is provided with burst disk 8.Be provided with high-tension shielding cover 3 between described fairlead 4 and the sleeve pipe 2.The outside of described sleeve pipe 2 is provided with silica gel sheath 9.
Insulation flashover in the utility model can be avoided Insulated Current Transformers to be in operation taking place guarantees the circuit operate as normal, guarantees the safe and reliable operation of product and network system.
