The cut-in method of use mainly has three kinds：
A kind of method that traditional access method is fastened using spanner and bolt：Terminal bolt on controller switching equipment busbar is dismantled
Connecting wire or needs punch wiring on busbar, then the cable of emergency power supply A, B, C phase and zero line is accessed into low-pressure side busbar
It is powered.Execute-in-place is limited by controller switching equipment installation site and busbar spacing sometimes, is wasted time and energy.
Another access method of the emergent interface of mobile stand-by power supply：Mobile stand-by power supply is not pre-installed to controller switching equipment
Emergent interface is reequiped, and it is higher to install cost additional, and utilization rate is not also high.
A kind of last U bolt formula clip switching method：Emergency power generation vehicle cable is first connected on the one of 4 external switchings respectively
End, then the other end is distinguished into clip on A, B, C phase low-pressure side busbar and zero line.Clip switching method can be by copper bar orientation
Limitation, is not suitable for transversely arranged copper bar；It is more painstaking during assembly and disassembly, and easy-to-use fastener shifts even on copper bar
Come off.
The content of the invention
The purpose of this utility model is that there is provided a kind of emergency power generation vehicle 0.4kV in order to overcome the shortcoming of above-mentioned prior art
Power supply quickly accesses the access device of user side, and emergency power generation vehicle 0.4kV power supplys quickly access the access device solution of user side
Conventional spanner of having determined plus the method for bolt fastening take 20-30 minutes；Clip forwarding method takes 10-15 minutes, and can be achieved should
Energy is quick respectively for four connectors of urgent telegram source A, B, C phase and zero line, reliably and securely access low-pressure side busbar, takes less than 5
Minute completes connection and is powered；In the case where carrying out reliable protection measure, and it can reduce client with powered completion access operation and stop
The electric time.With safety, it is quick, reliable the characteristics of, access device is applicable to the controller switching equipment busbar of all kinds of specifications, nothing respectively
It need to be fastened, and can quickly accessed, with good current-carrying capacity and insulating capacity, when shortening the access of emergency power supply using bolt
Between, the continuous reliable electricity consumption of user is ensured, power emergency ability is improved, improves power supply with protecting electrical efficiency.
The utility model solves the technical scheme that its technical problem used：A kind of emergency power generation vehicle 0.4kV power supplys are fast
The access device of fast accessing user side, including copper coin, it is respectively arranged on the left hangers and right hangers of copper coin both sides, located at copper coin one end
And the copper pincers component that two copper clamp composition is symmetrical arranged with copper coin cross central line, set two layers of bronze medal to clamp component and be simultaneously respectively arranged on copper
The top and bottom of plate, copper pincers are articulated with copper coin and are cased with realizing the spring of self-return, and spring is placed on copper pincers above and pacified
In mounting hole loaded on copper coin；One end of left hangers and right hangers is located at copper coin sidepiece, and the other end is mutually fastened or split
Form loop connection.
Further, two copper pincers are symmetrical arranged to form a pincerlike bayonet socket, and the width of pincerlike bayonet socket is from outside to inside gradually
Narrow.Locked after access by pincerlike bayonet socket or adjustable mode, anti-locking apparatus comes off.
Further, the described copper coin other end is provided with the copper billet being connected with emergency power generation vehicle cut cable and reserves wiring
Hole.
Further, insulating sleeve or prefabricated insulating gum cover are cased with described left hangers and right hangers.Using insulation sleeve
Pipe or prefabricated insulating gum cover are taken up, with good insulation characteristic.
Further, copper jaw surfaces are silver-plated or tin plating.
In summary, access device of the present utility model is the new connection structure of emergency power generation vehicle and controller switching equipment busbar
Part, every copper pincers composition lamination combining type structure, with auto-reset function（Also self-compensating function can be）, clamping force is with connecing
Touch busbar area and increase（It is inserted perpendicularly into busbar）, the copper pincers component point each layer of double-layer structure, which is, independently to be patched, every layer of copper pincers
Component can independently swing, the two-sided independent compression of copper pincers component, not involve mutually.The copper pincers component of the structure is to use busbar
Produce bending or area is wide and disalignment is not more than 2mm, every layer of copper pincers component can ensure that and be pressed from both sides with bus contact area
Close, it is ensured that mutual through-current capability.The controller switching equipment busbar of all kinds of specifications is applicable to, without bolt, power supply is improved with protecting electricity effect
Rate.In scheduled overhaul, can in advance by generator car and civil power it is grid-connected after, then disconnect civil power, power supply free of discontinuities can be accomplished, lifting is supplied
Electricity consumption both sides' effectiveness of operation.The static pressure and spring for clamping the two-sided independent hold-down gear of component using copper mutually press from both sides double two panels copper pincers
Tightly, every piece of copper sheet size is about the mm of 60mm × 50, and thickness 8mm, total current-carrying capacity is about 800~1000 peaces, is in close contact with busbar
Part temperature rise must not exceed 45K, and the temperature rise of electric-conductor contact site is no more than 50K.Access after controller switching equipment busbar by pincer card
Mouthful or adjustable mode locked, effectively prevent from coming off, with conveniently, safely, fast, it is reliable the characteristics of.Can quickly access,
With good current-carrying capacity and insulating capacity, operations staff's workload is reduced, operating efficiency is improved, it is ensured that equipment safety is reliably transported
OK.
