Abstract
The utility model discloses a closed intensive busbar bridge. The closed intensive busbar bridge comprises four groups of connecting busbars positioned in a shell, wherein the connecting busbars penetrate through the shell, and the two ends of each connecting busbar are respectively provided with a soft connector; and the soft connectors are respectively fixedly connected with a leading-out busbar of a distribution cabinet and a secondary-side joint of a transformer, and the lower part of the shell is fixedly connected to a support frame. According to the closed intensive busbar bridge, as the soft connectors are adopted at the joints, the shape processing of the leading-out busbar of the distribution cabinet or a transition joint on the wire outlet side of the transformer is avoided, the distance among the distribution cabinet, the busbar bridge and the transformer does not need to be precisely measured, and the mounting difficulty is reduced. Due to the sealing property of the busbar bridge, after the closed intensive busbar bridge is put into use, the closed intensive busbar bridge is not in direct contact with an environment, the short-circuit phenomenon caused by dust accumulation on the busbars is avoided, and the safety performance of the busbars is further improved. When cleaning and overhaul of lighting are performed in a transformer room, the direct contact between a person and the busbars is avoided, professional staff is not required during daily maintenance work, and the maintenance cost of a low-voltage transformation and distribution room is reduced.
Description
Technical field
The utility model relates to the connection bus bridge of Circuit Fault on Secondary Transformer outlet to power distribution cabinet inlet wire in a kind of low-voltage power supply and distribution system, relates in particular to the low pressure that a kind of dust is more, dust stratification is more serious and becomes the distribution environment with closed intensive bus bridge.
Background technology
At present the connection bus of Circuit Fault on Secondary Transformer outlet to power distribution cabinet inlet wire all adopts exposed bus in the low-voltage power supply and distribution system, and all adopts copper with transformer, power distribution cabinet junction or aluminum plate shape bus is connected firmly at bus.Transformer causes power distribution cabinet bus, power distribution cabinet, and to draw bus be plate shape metal material (general busbar cross-section long * wide be 100 * 10); Because the installation site of two kinds of buses and angle are different; Make when bus is installed; Must do certain shapes processing (bending etc. like brace) at transformer, power distribution cabinet with the bus junction could be connected two kinds of buses normally, has strengthened installation difficulty like this.In addition, in the switchgear house normal course of operation, because bus is exposed, dust stratification is difficult to avoid on the bus, causes the short circuit between the bus easily, and serious accident takes place.And because bus exposed, make the regular maintenance of transformer room, like hygienic cleaning, difficulty very during the illumination maintenance must let the professional implement during maintenance, cause the year maintenance maintenance cost that becomes switchgear house in rising trend year by year like this.
The utility model content
The purpose of the utility model is to provide a kind of and reduces installation difficulty, the raising bus operational safety performance that low pressure becomes the switchgear house connection bus, and reduces the closed intensive bus bridge that low pressure becomes switchgear house regular maintenance cost.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of closed intensive bus bridge comprises four groups of connection buss that are positioned at shell, and said connection bus runs through shell, and two ends are respectively equipped with and are flexible coupling; Said be flexible coupling draw bus with power distribution cabinet respectively and be fixedly connected with the transformer secondary side connector, said outer casing underpart is fixedly connected on the bracing frame.
Said connection bus is fixedly connected with shell through Bus line cramp, and intensive being integral.
Between the said connection bus, be provided with insulation filler between connection bus and the shell.
The said two ends that are flexible coupling are respectively copper coin, and an end is fixedly connected with connection bus, and the other end draws bus with power distribution cabinet or the transformer secondary side connector is fixedly connected; The ropy that the said middle part that is flexible coupling is compiled into for the copper cash that is fixedly connected with the two ends copper coin.
The said total sectional area that is flexible coupling the middle part copper cash is not less than the sectional area of termination copper coin.
The closed intensive bus bridge that the utility model provides; Because adopting, the junction is flexible coupling; Avoided power distribution cabinet is drawn bus or transformer outlet side transition joint is done processing in shape; Need not the distance between power distribution cabinet, bus bridge, the transformer is accurately measured, reduced installation difficulty.Because the sealing of bus bridge, not have directly with environment in the back of coming into operation and to contact, the short circuit phenomenon of having avoided the bus laying dust to cause has afterwards improved the security performance of bus.The transformer room has avoided the people to contact with the direct of bus when sweeping health and repairing lighting, does not need professional, common electrician just can safeguard in the line service, has reduced low pressure and has become the switchgear house maintenance cost.

Among the figure: the 1-shell, 2-connection bus end, 3-is flexible coupling, 4-transformer secondary side connector; The 5-transformer, the 6-bracing frame, the 7-power distribution cabinet, the 8-power distribution cabinet is drawn bus; The 9-connection bus, 10-insulation filler, 11-connecting bolt, 12-Bus line cramp; 13-connecting bolt, 14-copper coin, the 15-middle part that is flexible coupling.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the utility model is done further to specify.
As shown in Figure 1; A kind of closed intensive bus bridge comprises four groups of connection buss 9 that are positioned at shell 1, and connection bus 9 runs through shell 1; Connection bus 9 two ends are connected with bolt respectively and are flexible coupling 3; Be flexible coupling and 3 draw bus 8 with power distribution cabinet 7 respectively and be connected with transformer 5 secondary side joints 4 usefulness bolt, the bottom of shell 1 is fixedly connected on the bracing frame 6 with bolt 11, and bracing frame 6 is fixed on ground.
As shown in Figure 2, shell 1 is made up of four iron plates, and the iron plate of upper and lower is fixedly connected through Bus line cramp 12 usefulness bolts 13, and the iron plate of both sides is fixedly connected with the iron plate of upper and lower through bolt 13.Connection bus 9 comprises A phase, B phase, C phase and zero line, intensive being integral between them, compact in design, good sealing effect.Between the connection bus 9, be provided with insulation filler 10 between connection bus 9 and the shell 1.
As shown in Figure 3,3 the two ends of being flexible coupling are respectively copper coin 14, one ends and are connected with connection bus 9 usefulness bolt, and the other end draws bus 8 with power distribution cabinet or transformer secondary side connector 4 usefulness bolt are connected.The use 1mm of middle part 15 for being fixedly connected with two ends copper coin 14 is flexible coupling
