Description
Technical Field
The utility model relates to a low voltage generator car protects the power supply field, concretely relates to low voltage generator car protects lapped bridging device of convenient cable of power supply usefulness.
Background
Along with the development of science and technology and the progress of society in recent years, the improvement of people's living standard, the continuous increase of power consumption, electricity has become the indispensable component of people's daily life, in case the power failure problem has appeared and has caused a great deal of inconvenience for people's life and work, consequently the reliability of supplying power becomes one of the important index of power supply service quality, this index promotes the continuous improvement of whole power supply level, wherein utilize low-voltage generator car to carry out the power supply to the switch board because of the construction power failure, also is one of the important measure of reducing the house number when having a power failure.
The low-voltage power generation car is used for guaranteeing power supply, and power needs to be cut twice before and after power supply is guaranteed. At present, when the power supply of a power generation car is guaranteed, about 70-120 minutes is needed for each power failure. How to shorten the power failure duration when the power generation car guarantees to supply power work becomes the problem of utilizing the key concern of low pressure power generation car guarantee power supply. The inventor finds that the cable assembly and disassembly time of the power failure operation is long when the low-voltage generator car is protected for power supply at present through investigation and research, the average time is between 50 and 90 minutes, and the long time consumption of the power failure operation of the low-voltage generator car is the symptom. Further, the inventor finds that when the existing low-voltage power generation car is used for cable lap joint during power supply protection, the original nut on the stud of the busbar or the wiring pile head of the power distribution cabinet needs to be unscrewed, then the copper nose at the end part of the cable of the low-voltage power generation car is sleeved on the stud of the busbar or the wiring pile head of the power distribution cabinet, and the original nut is locked to complete cable lap joint (the cable lap joint operation processes all need to operate in a power failure state, namely the existing cable lap joint needs to disassemble the original nut and install the original nut, and the two operation steps are carried out); when the cable is disassembled, the original nut on the stud of the wiring pile head or the busbar of the power distribution cabinet needs to be unscrewed, then the copper nose at the end part of the cable of the low-voltage power generation vehicle is taken down, and then the original nut is locked on the stud of the wiring pile head or the busbar of the power distribution cabinet again (the above cable disassembling operation process needs to operate in a power failure state, namely the original nut needs to be disassembled and the original nut needs to be locked again when the cable is disassembled at present, and the two operation steps are adopted). The cable assembling and disassembling method has the advantages that operation steps are multiple when the cable is assembled and disassembled when the low-voltage generator car is protected for power supply at present, and therefore the problem that long time is consumed for assembling and disassembling the cable when the low-voltage generator car is protected for power supply is caused. On the other hand, the original nuts on the studs of the busbar or the wiring pile heads of some power distribution cabinets can be corroded frequently in the long-time use process, so that the original nuts on the studs of the busbar or the wiring pile heads of the power distribution cabinets are not easy to detach, and the cable taking time is further prolonged.

Similarly, compare in the power failure operation "when cable dismantlement among the prior art and need dismantle the original nut of original device and install the original nut once more, these two operating procedure" compare, the bridging device of this scheme of use, cable dismantlement power failure operation when the power supply is protected to the low voltage generator car, only need to dismantle the bolt of the copper nose and the electrically conductive bridging member of the cable tip of connecting the low voltage generator car, then take off the cable of low voltage generator car can, the original nut of installing the original device step has been saved, thereby effectively simplify the power failure operation step of cable dismantlement when the power supply is protected to the low voltage generator car, and then it is long when effectively shortening the power failure operation of cable dismantlement when the power supply is protected to the low voltage generator car.
Preferably, the conductive lap joint is a conductive lap plate, and the included angle between the conductive lap plate and the axis of the conductive lap nut is less than 10 degrees. So, when installing on the double-screw bolt of female arranging or wiring pile head of electrically conductive overlap joint nut to the switch board, can effectively avoid electrically conductive overlap joint board and all the other parts of switch board to take place to interfere.
Preferably, the conductive strap is parallel to the axis of the conductive strap nut. So, when installing on the double-screw bolt of female arranging or wiring pile head of electrically conductive overlap joint nut to the switch board, can further effectively avoid electrically conductive overlap joint board and all the other parts of switch board to take place to interfere.

Therefore, the thickness of the conductive lapping plate is set to be 1-5 mm in the scheme, so that the strength of the conductive lapping plate is ensured.
Preferably, the conductive strap is fixedly connected to a side surface of the conductive strap nut. So, be favorable to improving the area of contact of electrically conductive overlap joint spare and electrically conductive overlap joint nut to improve the electrically conductive efficiency between electrically conductive overlap joint spare and the electrically conductive overlap joint nut.
