Abstract
Disclosed is a CT wire jumping pipe type bus-bar fitting which comprises a pipe type bus-bar clamp. The CT wire jumping pipe type bus-bar fitting is characterized in that two groups of wires are connected to the pipe type bus-bar clamp and arranged on two sides of the pipe type bus-bar clamp respectively, each group of wires includes one or more wires, and one end of each group of wires is connected with a CT device clamp, a base insulator is arranged under the pipe type bus-bar clamp, grading and shielding rings are arranged on the upper and lower sides of the pipe type bus-bar clamp, and a support fixed on the base insulator is arranged between the two grading and shielding rings. The CT wire jumping pipe type bus-bar fitting has the advantages that displacement generated from earthquake, wind vibration and expansion with heat and contract ion with cold can be compensated, damage to a connection portion is prevented; and by aid of further arrangement of the grading and shielding rings in the fitting, the pipe type bus-bar clamp is shielded completely, and coronas of the pipe type bus-bar clamp is avoided. The CT wire jumping pipe type bus-bar fitting is mainly used in connection between a CT device and the pipe type bus-bar in power stations, and is in particular suitable for connection between the CT device and the pipe type bus-bar in the power stations in Qinghai-Xizang region which has frequent earthquakes and great temperature difference between day and night.
Description
Technical field
The utility model belongs in a kind of power circuit manages bus connecting device, particularly a kind of CT lead jumper connection pipe capital tool that is applied in the transformer station.
Background technology
At present; CT equipment with the mode that adopts that is connected of pipe bus is: the external part daughter board is communicated with the pipe bus through the pipe bus clip from CT equipment; This connection is a rigidity, and earthquake, aeolian vibration, expand with heat and contract with cold etc. all can cause damage to the junction, and serious meeting causes the outage of whole transformer station; Influence several line powerings, tend to cause the loss of tens million of units.
Summary of the invention
The technical problem that the utility model will solve provides a kind ofly can realize bit shift compensation, prevent the CT lead jumper connection pipe capital tool of the hurtful connection in junction CT equipment with the pipe bus.
The CT lead jumper connection pipe capital tool that the utility model relates to comprises the pipe bus clip, and its special character is: on the pipe bus clip, be connected with two groups of leads; Described two groups of leads are arranged in pipe bus clip both sides, and every group of lead has one or more, and every group of lead other end is connected with the CT device clamp; Below the pipe bus clip, be provided with base insulator; Upper and lower respectively being provided with of pipe bus clip all pressed shading ring, all presses at two to be provided with support between shading ring, and described support is fixed on the base insulator.
Above-mentioned CT lead jumper connection pipe capital tool, described CT device clamp is made up of two bolt type dual lead device clamps, has connecting bolt on the described bolt type dual lead device clamp.
Above-mentioned CT lead jumper connection pipe capital tool, the length of described lead is greater than the distance between CT device clamp and the pipe bus clip.
Above-mentioned CT lead jumper connection pipe capital tool when every group of lead is many, is provided with the insulation separaant between per two leads.
The utility model has the advantages that: make to be rigidly connected to become through the method that between CT device clamp and pipe bus clip, adds lead to flexibly connect.This connection can compensate the displacement of shaking, expanding with heat and contract with cold and producing because of earthquake, wind, reduces stress thereby reach, and increases reliability, prevents the junction is caused damage.Owing to add in the gold utensil and all press shading ring, will manage bus clip and shield fully, avoided pipe bus clip corona.The utility model is mainly used in each power station CT equipment and pipe being connected of bus, and is particularly useful in earthquake takes place frequently, day and night temperature the is big power station, area, Qinghai-Tibet CT equipment and manages being connected of bus.
