Abstract
The utility model discloses a 35kV low-voltage side incoming line configuration structure. A jumping line is introduced from a main transformer bus and is vertically connected with a 35kV bus. The jumping line is provided with an insulating switch, a circuit breaker and a current transformer successively. The 35kV low-voltage side incoming line configuration structure has the following advantages: compact integral layout, and small occupation area. Furthermore, another set of equipment can be equipped at opposite side of the inlet line separately, and therefore the space is sufficiently used.
Description
Technical field
The utility model relates to a kind of 35kV low-pressure side inlet wire arrangement.
Background technology
Original 35kV low-pressure side inlet wire arrangement, main transformer bus 1 is conventional along the female inlet wire mode of pipe, as shown in Figure 1 with 35kV bus 2.In this case, isolating switch 3, circuit breaker 4, current transformer 5 all are arranged on the 35kV bus 2.For guaranteeing electrical safety, should guarantee the safe distance of 2.5-3m between above-mentioned isolating switch 3, circuit breaker 4, the current transformer 5, this arrangement is compact inadequately, and floor space is bigger.
In addition, as shown in Figure 3, traditional bus-bar potential transformer 9 is positioned at the side of 35kV bus 2, and integral layout is in disorder and not compact.
Summary of the invention
The purpose of this utility model provides a kind of floor space and compact 35kV low-pressure side inlet wire arrangement of layout of reducing.
For achieving the above object, the utility model is by the following technical solutions:
A kind of 35kV low-pressure side inlet wire arrangement is drawn wire jumper from the main transformer bus, and wire jumper is connected with the 35kV bus is vertical; On described wire jumper, set gradually isolating switch, circuit breaker summation current transformer.
Corner at described wire jumper is provided with post insulator.
Arranged beneath voltage transformer at the 35kV bus.
Adopt the utility model of technique scheme, 35kV low-pressure side inlet wire mode is optimized for perpendicular to 35kV pipe generatrix direction inlet wire, the integral layout compactness, floor space is less.In addition, inlet wire offside at interval can also be arranged another one equipment at interval, has made full use of the space.
Description of drawings
Fig. 1 is conventional along the female inlet wire mode figure of pipe.
Fig. 2 is inlet wire mode figure of the present utility model.
Fig. 3 is the arrangement figure of conventional voltage instrument transformer.
Fig. 4 is the arrangement figure of voltage transformer in the utility model.
Embodiment
As shown in Figure 2, a kind of 35kV low-pressure side inlet wire arrangement, it draws wire jumper 7 from main transformer bus 1, wire jumper 7 and 2 vertical connections of 35kV bus, promptly perpendicular to 35kV pipe bus 2 direction inlet wires, the corner at described wire jumper 7 is provided with post insulator 8 simultaneously.On wire jumper 7, set gradually isolating switch 3, circuit breaker 4 summation current transformers 5 then.
In addition, be erected on the 35kV bus structure 6 at 35kV bus 2, and at the arranged beneath voltage transformer 9 of 35kV bus 2.
Claims (3)
1. a 35kV low-pressure side inlet wire arrangement is characterized in that: draw wire jumper (7) from main transformer bus (1), wire jumper (7) and vertical connection of 35kV bus (2); On described wire jumper (7), set gradually isolating switch (3), circuit breaker (4) summation current transformer (5).
2. 35kV low-pressure side inlet wire arrangement according to claim 1 is characterized in that: the corner at described wire jumper (7) is provided with post insulator (8).
3. 35kV low-pressure side inlet wire arrangement according to claim 1 is characterized in that: at the arranged beneath voltage transformer (9) of 35kV bus (2).
