Description
Technical field
The present invention relates to a kind of electric power access device, especially a kind of low pressure is confluxed master clamp.
Background technology
Electric reliability requires more and more higher at present, to ensure that user does not have a power failure, meets an urgent need and protects electricity, power transmission, interim power taking, confession
The operating mode of electricity is more and more common, ensures that user power utilization demand has become normality by using jury rig power supply or power taking.
Emergency service for 0.4kV user or power taking operation at present, be by by jury-rigged connecting cable with
The low-voltage distribution cabinet connection of user, is transferred to another user, China's distribution at present by jury rig to customer power supply or power taking
The low-voltage distribution cabinet used is the standard distributed cabinet of GGD or GCK patterns, and internal interface is low-voltage busbar, general nothing on busbar
Mounting hole has remaining mounting hole, and standard differs, need to be by jury-rigged connecting cable termination and busbar upper installing hole during operation
Or punch and be connected by screw bolts on busbar again.
Due to the spacing very little of busbar or other electrical bodies, the access operation of cable must be completed under power down mode, mesh
There is the access that two methods realize cable as previous, one kind is that spare interface or reserve tank are pre-set on low-voltage distribution cabinet, electricity
Cable accesses spare interface or reserve tank under power down mode, then by the switch power transmission in spare interface or reserve tank, realizes
User's normal electricity consumption of low-voltage distribution cabinet is not influenceed when power supply or power taking, but is that needs are matched somebody with somebody to normal low pressure the shortcomings that the program
Electric cabinet transformation, pre-sets spare interface or reserve tank, and cost of investment is high, and utilization rate of equipment and installations is low；Using short during another method
When the mode that has a power failure cable is directly accessed into low-voltage distribution cabinet, be advantageous in that investment is low, access is simple, but access procedure needs pair
The user of former low-voltage distribution cabinet is had a power failure, it is impossible to meets the reliability requirement that responsible consumer does not have a power failure.
Therefore, jury-rigged connecting cable accesses the problem of busbar in low-voltage distribution cabinet under live state, at present
It there is no known technology solution.
The content of the invention
For problem above, conflux master clamp the invention provides a kind of low pressure, solve emergency guarantee equipment cable in band
The problem of busbar in low-voltage distribution cabinet is accessed under electricity condition.
The technical solution adopted by the present invention is as follows：
A kind of low pressure is confluxed master clamp, including the bar that confluxes, and bar one end of confluxing sets busbar fixture, and the other end sets connecting seat, its
Middle busbar fixture includes the neck that can be caught in busbar, and the fastener that can fasten the busbar being caught in is set in neck；Connection
Connector is set on seat；The busbar fixture, the bar that confluxes, the outer surface of connecting seat and fastener are respectively provided with insulating protective layer.
Further, described low pressure is confluxed master clamp, and the neck can be U-type groove.
Further, described low pressure is confluxed master clamp, and the fastener can be fastening bolt, one side of the neck
Bolt hole is provided with, the fastening bolt is arranged in bolt hole, and fastening is realized by the spiral in bolt hole.
Further, described low pressure is confluxed master clamp, is set in the neck relative with the bolt hole position trapezoidal
Gap, conductive spring leaf is installed in the trapezoidal gap.
Further, described low pressure is confluxed master clamp, and the fastening end of the fastening bolt sets the solid plate of pressurization, described
The solid plate of pressurization is the plate that diameter is more than fastening bolt fastening end diameter, is set on the solid plate of pressurization and reinforces pressing plate dovetail groove.
Further, described low pressure is confluxed master clamp, and the both ends of the bar that confluxes are respectively provided with transition connection step.
Further, described low pressure is confluxed master clamp, and the quantity of the connecting seat is multiple, passes through pole of confluxing respectively
Bar is connected with confluxing.
Further, described low pressure is confluxed master clamp, sets powered indicator lamp and connecting seat dust-proof on the connecting seat
Cap.
Further, described low pressure is confluxed master clamp, and the insulating protective layer set on the connecting seat can be along connecting seat
Axial opening and closing.
Further, described low pressure is confluxed master clamp, and anchorage bar installing port is provided with the fastening bolt, is passed through
The anchorage bar coordinated with the anchorage bar installing port realizes the fastening of fastening bolt；The fastening rod outer surface is respectively provided with insulation and protected
Sheath.
Further, busbar fixture described above and the bar that confluxes are that conductive material makes；The anchorage bar by stock,
Cross bar, fastening interface, insulating barrier composition；Overall parcel insulating protective layer outside the anchorage bar；Described anchorage bar one end is set
Fasten interface；The fastening interface and anchorage bar installing port are supporting；The anchorage bar other end sets cross bar；Cross bar and anchorage bar
Perpendicular connection.
Scheme as a further improvement on the present invention, the U-type groove front end face can be zigzag；Further improving connection can
By property and stability.
The present invention compared with prior art, has the advantages that：
（1）Because low pressure is confluxed, master clamp outside is overall to wrap up insulating barrier, and low pressure confluxes master clamp in access low-voltage distribution cabinet
It is overall to keep insulation during busbar, thus avoid low pressure conflux cause in master clamp access procedure because busbar spacing is small and
The problem of causing phase fault, solve the problems, such as that jury rig cable accesses busbar in low-voltage distribution cabinet under live state；
（2）Because low pressure master clamp one end of confluxing sets busbar fixture, busbar fixture can directly be caught in the mother in low-voltage distribution cabinet
On row, therefore whether the conflux access of master clamp of low pressure is not had mounting hole to be influenceed by the busbar in low-voltage distribution cabinet, can be direct
Connection；
（3）Due to setting fastener in the neck of busbar fixture, it is possible to achieve to the fastening for the busbar being caught in, fasten after compressing,
Solve the problems, such as that low pressure is confluxed the connection reliability of master clamp；
（4）Due to low pressure conflux master clamp neck internal clamp outer surface set insulating protective layer, fastener is in fastener cycle
Be completely disposed in insulation protection, thus fastener pass through in fastener cycle with busbar in low-voltage distribution cabinet or other electrical bodies it is exhausted
Edge protective layer is isolated, and avoids short trouble；
（5）Due to overall parcel insulating barrier outside anchorage bar, during anchorage bar screws or unscrews fastening bolt, anchorage bar is whole
Body insulate, therefore anchorage bar is in low-voltage distribution cabinet between busbar during operation, can avoid it is short-circuit caused by contact electrical body therefore
Barrier；
（6）Because the low pressure master clamp tail end that confluxes sets connecting seat, connector is set on connecting seat, the connector can be screw thread
Hole, jury-rigged cable one end crimp type terminal, it is connected by stud with screwed hole, therefore different length or the cable of specification are equal
The connection with connecting seat can be realized by stud, realizes the height interchangeability of cable.
