Description

The unsettled fixed support instrument of a kind of power transmission line overhead ground wire
Technical field
The utility model relates to the unsettled fixed support instrument of a kind of power transmission line overhead ground wire.
Background technology
Be eliminate the line parameter circuit value uneven impact on circuit relay protection performance during three phase line erection; line phase-sequence detection transposition need be carried out; the overhead ground wire that certain distance erection is corresponding above three phase line simultaneously; to eliminate the positive and negative Zero sequence parameter imbalance of three phase line that electromagnetic unbalance causes; thunder-strike current is directly imported grounding net of transformer substation simultaneously; prevent thunder and lightning direct stroke frame three-phase ceases to be busy road, cause three phase line disconnection fault.Therefore; development erection is convenient; effectively can hang fixed retainer vacant lot line, guarantee that three phase line triphase parameter balances, the power transmission line overhead ground wire unsettled fixed support instrument improving relay protection of transmission line Reliability of Microprocessor has very important practical engineering value.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing; namely technical problem to be solved in the utility model is to provide a kind of erection conveniently; effective suspension fixed retainer vacant lot line; guarantee that three phase line triphase parameter balances, improve the unsettled fixed support instrument of power transmission line overhead ground wire of relay protection of transmission line Reliability of Microprocessor.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the unsettled fixed support instrument of a kind of power transmission line overhead ground wire, comprise an insulating bar, one end of described insulating bar is arranged with two fixtures, described fixture comprises two intermediate plates, the other end of described two pieces of intermediate plates is provided with screwed hole, screw is provided with in this screwed hole, the two ends of described screw are provided with dead ring respectively, described two dead rings are connected by a chain, the other end of described insulating bar is arranged with connector, the other end of described connector is arranged with lengthened insulative bar, the other end of described lengthened insulative bar is provided with pullover, described pullover end is provided with hanging ring, described hanging ring is used for hanging overhead ground wire.
Further, described connector and to be pulloverly all fixed on insulating bar by rivet.
Compared with prior art, the utility model has following beneficial effect: the utility model erection is convenient, effectively hangs fixed retainer vacant lot line, guarantees that three phase line triphase parameter balances, and improves relay protection of transmission line Reliability of Microprocessor.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
