Abstract
The utility model discloses a novel cable line pi connection system for a transformer substation. The pi connection system comprises a pole; a support cross arm is arranged along the vertical direction of a cable line and at the top of the pole; carrying pole supportings are respectively arranged along the parallel direction of the cable line and at the two ends of the support cross arm; suspended lightning arresters are respectively arranged at the two end of the carrying pole supportings; cables below the suspended lightning arresters are fixed via the pole; and the middle part of the support cross arm is fixed on and parallel with the pole. By adopting a carrying pole principle design, forces applied onto components at the two ends of the pi connection system are balance, the arrangement of the two ends are symmetrical and reasonable, the support structure is simple and clear, the structure is compact and reasonable, and a demand for the electric apparatus safety distance of the plurality of lightning arresters can be fully met.
Description
One, technical field:
The utility model relates to a kind of cable line, particularly relates to a kind of novel cable line π of transformer station welding system.
Two, background technology:
Transformer station increases sharply along with the city, and corresponding supporting cable line adopts π to connect mostly or T connects existing overhead transmission line, and this just requires π extension bar (tower) to have characteristics such as floor space is little, rational in infrastructure, connecting line disconnected, and is handsome in appearance.
Present π link all be to from a direction of circuit go into ground situation; The suspension of parts such as lightning arrester, cable termination, the fixing requirement of satisfying the security appliance distance easily; But when need to both direction go into the ground situation time, on same line bar each parts to satisfy security appliance apart from the time difficulty relatively just.
Three, utility model content:
The utility model technical problem to be solved is: a kind of novel cable line π of transformer station welding system is provided, and according to " shoulder pole " principle, fulcrum is at the center; The identical lightning arrester of two ends suspension; Stressed identical, remain balance, and make the suspension of lightning arrester satisfy the requirement of security appliance distance.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of novel cable line π of transformer station welding system; Comprise the line bar; Said line bar top is provided with the support cross-arm along the cable line vertical direction, and said support cross-arm two ends are provided with shoulder pole respectively along the cable line parallel direction and support, and two shoulder poles support two ends and are respectively arranged with suspended-type surge arrester.
The logical mast of cable of said suspended-type surge arrester below is fixed.
On the online bar of said support cross-arm center fixed, vertical with the line bar.
The positive beneficial effect of the utility model is following:
1, the utility model is provided with the support cross-arm through online bar top along the cable line vertical direction; Said support cross-arm two ends are provided with shoulder pole respectively along the cable line parallel direction and support; Two shoulder poles support two ends and are respectively arranged with suspended-type surge arrester, make a plurality of lightning arresters satisfy the requirement of security appliance distance like this.
2, the utility model utilization shoulder pole principle design makes each parts stress balance of both sides, and the two ends symmetrical arrangement is reasonable, and supporting construction is simple and clear, and compact conformation is reasonable, has simplified the mode of connection.
Four, description of drawings:
Fig. 1 is the structural representation of the utility model.
Five, embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1; A kind of novel cable line π of transformer station welding system; Comprise line bar 5, line bar 5 tops are provided with along the cable line vertical direction and support cross-arm 1, and said support cross-arm 1 two ends are provided with shoulder pole respectively along the cable line parallel direction and support 2; Two shoulder poles support 2 two ends and are respectively arranged with suspended-type surge arrester 3, and the cable 4 logical masts 5 of suspended-type surge arrester 3 belows are fixed; On the online bar 5 of said support cross-arm 1 center fixed, vertical with line bar 5.
This utility model utilization shoulder pole principle design makes each parts stress balance of both sides, and the two ends symmetrical arrangement is reasonable, and supporting construction is simple and clear, and compact conformation is reasonable, makes a plurality of lightning arresters can fully satisfy the requirement of security appliance distance.
