Description

Overlapping device and method for power-generating car power protection and power supply capable of shortening power failure time
Technical Field
The invention relates to the field of power supply of low-voltage generator cars, in particular to a lapping device and a lapping method for power supply of generator cars, which can shorten the power failure time.
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 more 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 the cable is long in assembling and disassembling time 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.

When the lap joint device is used for protecting the power supply of the low-voltage power generation car, an operator can directly lock the conductive lap joint nut on a bus bar or a stud of a wiring pile head of a power distribution cabinet by the insulating protective clothing without power failure (the original nut on the bus bar or the stud of the wiring pile head of the power distribution cabinet is not required to be screwed off); and then, the circuit is disconnected, and power failure operation is carried out, namely, the bolt penetrates through the copper nose at the end part of the cable of the low-voltage generator car and the connecting through hole of the conductive lapping piece, so that the copper nose at the end part of the cable of the low-voltage generator car is locked on the conductive lapping piece, and the lapping of the cable is completed.
