Description
Technical field
The invention belongs to high-voltage electrical appliances fields, especially with regard to a kind of outdoor high voltage cable branch box switchgear.
Background technique
Outdoor high voltage cable branch box is used for the connection and tap of power cable, generally by shell, with insulating protective layer
Busbar, connecting cable and cable connector composition.Such as the High-Voltage Cable Branching Case of number of patent application CN200720099790.9, packet
It includes shell, the intracorporal bracket of the shell is set, multiple cable inner cone plugging formula connectors are housed on the bracket, it is described
Shell be made of glass fiber reinforcement unsaturated polyester layer.With lightweight, anti-condensation, corrosion-resistant, ageing-resistant, all insulation, resistance
The features such as combustion.Its major defect is that apparatus insulated grade is low, and the power-frequency voltage born is 42kV/1min, lightning impulse voltage
85kV(peak value), it may be only available for the electric system of 12kV voltage class.
Summary of the invention
The purpose of the present invention is being directed to existing deficiency, a kind of class of insulation height is provided, 24kV voltage etc. is suitable for
The joint-box of grade.
Technical solution of the present invention includes cabinet, cable and cable connector；Mainly cable connector is T-type insulation noose
Structure, the T-type insulation sleeve is interior to be equipped with connecting terminal, which is made of conductive clip, conductive tube and conductive core, and conductive clip is inserted
In the vertical cavity of T-type insulation sleeve, lower end have with the mutually matched inner hole of cable end conducting wire, upper end by screw with lead
One end of battery core is fixedly connected, and conductive tube is inlaid in the vertical cavity wall of T-type insulation sleeve, and upper end is electrically connected with conductive clip, lower end
It is sleeved on the periphery of cable accessory, T-type insulation sleeve vertical component lower port periphery is equipped with tightening device；Two T-type insulation
It is connected with each other between set by insulating bar, conductive core is encapsulated in the inner hole of insulating bar.
It is an advantage of the invention that cable connector is T-type insulation nested structure, two T-types are insulated by the insulating bar with conductive core
Cable in set is connected with each other, and makes to keep space length between every cable, prevents two cables from intersecting, and the class of insulation is high,
It can be used for the electric system of 24kV voltage class.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Joint-box as shown in Figure 1, including cabinet 1, cable 5 and cable connector 7；Cable connector 7 is T-type insulation sleeve
Structure, the T-type insulation sleeve is interior to be equipped with connecting terminal, which is made of conductive clip 10, conductive tube 8 and conductive core 4, leads
Electricity folder 10 is inserted into the vertical cavity of T-type insulation sleeve, and lower end has and the mutually matched inner hole of 5 end leads of cable, upper end
It is fixedly connected by screw 11 with one end of conductive core 4, conductive tube 8 is inlaid in the vertical cavity wall of T-type insulation sleeve, upper end and conduction
10 electrical connection of folder, lower end are sleeved on the periphery of cable accessory 6, and cable accessory 6 is conduct piece, upper end and 5 end leads of cable
Electrical connection, T-type insulation sleeve vertical component lower port periphery are equipped with tightening device 3, by cable accessory 6 and the fastening installation of cable 5
In cable connector 7, guarantee that the conducting wire of 5 end of cable is reliably electrically connected with conductive core 4；By insulating between two T-type insulation sleeves
Bar 12 is connected with each other, and conductive core 4 is encapsulated in the inner hole of insulating bar 12, insulating bar 12 make to keep between every outlet cable space away from
From preventing two cables from intersecting, insulator cap 13 installed on the T-type insulation sleeve at 12 both ends of insulating bar, T-type insulation sleeve outer surface is set
There is semi-conductive layer 9.
Cabinet 1 is equipped with charge indicating device 2, and the charge indicating device 2 is by being mounted on current detector and case on cable
Display composition on body, prompts the electrification of operator's route.
