Abstract
The utility model discloses a high tension switchgear current transformer and earthing switch are connected female structure of arranging, include the cabinet body, a looks current transformer and female row, B looks mutual -inductor and female row, C looks mutual -inductor and female arranging and the earthing switch operating axis, the female of C looks current transformer arranges to the board of bending, and this bends the board by the vertical board and the level of the upper and lower end of this the vertical board plate -type one -tenth recess of bending, the notch of board recess of bending is relative with the earthing switch operating axis. The utility model has the advantages of safe and reliable.
Description
Technical field:
This utility model relates to one high-tension switch cabinet forever, and particularly a kind of high-tension switch cabinet current transformer is connected the structure of busbar with earthed switch。
Background technology:
The current transformer of the cable vault of the middle-placed switch cabinet of high-tension switch cabinet is installed generally two ways, a kind of rear portion that current transformer is installed to middle-placed switch cabinet, and another kind is the bottom that current transformer is installed to middle-placed switch cabinet。In both mounting means, the busbar that connects between C phase current mutual inductor and earthed switch operates the electric clearance of the axle standard less than electrical safety distance 125mm from earthed switch, in order to overcome electric clearance apart from little defect, it is generally adopted and installs insulated sleeve additional on operation axle, but owing to equipment operating environment changes, insulation ag(e)ing, cause C to be connected busbar to ground connection switching manipulation axial discharge, cause personnel and equipment security incident。
Summary of the invention:
This utility model purpose is to provide a kind of safe and reliable high-tension switch cabinet current transformer and is connected the structure of busbar with earthed switch。
The technical solution of the utility model is, a kind of high-tension switch cabinet current transformer is connected the structure of busbar with earthed switch, axle is operated including cabinet, A phase current mutual inductor and busbar, B phase transformer and busbar, C phase transformer and busbar and earthed switch, it is characterized in that: the busbar of described C phase current mutual inductor is bending plate, this bending plate is formed groove by the horizontal bending plate of vertical plate He the upper and lower end of this vertical plate, and it is relative that the notch of described bending plate groove operates axle with earthed switch。
This utility model has safe and reliable advantage compared with the prior art。
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is the A-A profile of Fig. 1。
Detailed description of the invention:
Electric clearance between ground connection switching manipulation axle is easily caused the defect of security incident by the C existed to the solve prior art busbar that is connected less than 125mm, this utility model adopts following technical proposals, as shown in Figure 2, A phase current mutual inductor and B phase current mutual inductor are absent from more greatly potential safety hazard with the spacing operating axle, the mainly close together of C phase current mutual inductor, for this, structure connecting busbar 7 of C phase current mutual inductor is made bending plate, described bending plate is upper by riser and this riser, the horizontal plate of lower end forms groove, the groove port of this bending plate is relative with the operation axle of earthed switch, the distance between bending plate and operation axle is made to increase, and the standard of the 125mm much larger than regulation, make it have safe and reliable advantage。
To the control room 2 in cabinet 1, breaker chamber 3, bus-bar room 4 and cable vault 5, the busbar of A phase transformer 10, the busbar of B phase transformer 9 and C phase current mutual inductor 6 and earthed switch operation axle 8 etc. all without modification。
