Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in figure 1, a kind of cable branch box according to the utility model embodiment, including casing 9 and chamber door 7,
The top of the casing 9 is fixedly connected with case top 8, and glass door is provided between the chamber door 7 and casing 9, is set in the casing 9
Copper bar is equipped with, copper bar branch 6 is provided with the copper bar, the enter line side and outgoing line side of the casing 9 respectively set a powered display
Device, the electrification display include inductosyn 1 and the display window 3 electrically connected with the inductosyn 1, the sense
Inductive transducer 1 is electrically connected with the copper bar branch 6, and the display window 3 is arranged on the chamber door 7.
In a specific embodiment of the present utility model, the bottom of the casing 9 is provided with support frame, support frame as described above
Including the support platform being made up of channel-section steel 4, the bottom of the support platform is provided with some support posts 5.
In a specific embodiment of the present utility model, the side of the casing 9 is provided with arrester 2.
In a specific embodiment of the present utility model, the casing 9 is made up of metal foil or stainless steel plate, described
The thickness of metal foil or stainless steel plate is 2mm and handled using preservative treatment and spray painting.
In a specific embodiment of the present utility model, set in the casing 9 close to the position of the inner side of chamber door 7
It is equipped with glass door.
In order to facilitate above-mentioned technical proposal of the present utility model is understood, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
It is described in the utility model be fixedly connected with mode and the conventional technical means such as can be connected with, weld replace.
9 all metal foils of casing or stainless steel plate, thickness 2mm, handled using corrosion protection design and special spray painting,
Reliability service in adverse circumstances（Life-span >=30 year）.Outdoor round-the-clock, full protection structure, soaked suitable for high temperature, severe cold, flood
Bubble, the region of high dust.Using hermetically sealed, all insulation structure, without insulation distance, all silicon rubber in electrification in high voltage part or
EPDM.Prefabricated cable connector, is effectively ensured personal safety.
The bottom of casing 9 is provided with support frame, and aerial casing 9, which avoids ground hot gas, may cause casing 9 to hang water for a long time
Mist, mist caused by water smoke is reduced as far as possible and is dodged.
Electrification display is using the field coupling principle between high voltage electric field and sensor, is felt outside safe distance
Answer formula（It is contactless）Measurement, receives high-voltage charged body electric field signal, and send display window to and be compared judgement.In casing 9
An electrification display is respectively configured on interior inlet-outlet line interval, the display window 3 of electrification display is placed on chamber door 7 and each interval
Corresponding position, is easy to operations staff to observe.Electrification display is as judging a whether powered important evidence of equipment not
It is direct basis, can not thinks that the lamp on display window 3 extinguishes and be judged as equipment out of power, because indicator lamp or control line may
Break down.If the lamp on display window 3 is bright, it may be said that bright cable branch box is powered, reminds operating personnel to be careful not to open
Chamber door 7.If lamp, which extinguishes, can open chamber door 7, electrical verification operation is carried out, due to charging equipment all insulation, is then needed outside connect-disconnect plug
Portion's insulating lid and insulator are removed, and electrical verification is carried out by 10KV high voltage electroscopes.
High pressure observation window can be set in casing both sides, and high pressure observation window will consider the blast impact of short-circuit test, need to use
Implosion guard simultaneously installs explosion-proof net additional.For cost consideration, the utility model is provided with glass door between chamber door 7 and casing 9, its
With make, it is easy for installation, have a safety feature, the advantages of preventing electrostatic.After opening chamber door 7, glass door can play the work of isolation
With reminding operating personnel to pay attention to electrical body, by glass door it can be seen that situation in whole casing 9.
For the smaller or compact-sized cable branch box of casing, the difficulty for adding electrification display is larger or can not increase
Potential indicator, so the powered situation of casing can not be judged by electrification display, therefore, in the process of maintenance
In, the safety ground to cable branch box is just particularly important.
The cable unplugg of plug-in type cable branch box mainly by stud, insulator, insulating barrier, interior semi-conductive layer,
Stress cone, ground connection eye, outer semiconducting layer, crimp type terminal, rear end cap composition.In current maintenance process, cable branch box stops
The rear end cap of cable unplugg is opened after electricity, instrument is reused after electrical verification insulator is taken out into ground connection.Because what is used at present
It is too short to take out the instrument of cable unplugg insulator, it is compact-sized if the casing of cable branch box is smaller, taken using instrument
Certain danger during going out insulator be present, so lengthening improvement can be carried out to cable unplugg, with increase operation
Security performance.
Electrical verification needs to be grounded cable branch box after terminating, using connecting screw and the cable branch box that at present uses
Ground wire, which is connected, is made the connecting screw with grounding function, and discharge process is first carried out to it after taking out insulator, then will tool
Cable branch box is grounded in the cable unplugg that the connecting screw access for having grounding function lengthens.
To sum up, by means of above-mentioned technical proposal of the present utility model, as long as former not belt switch plug-in type cable feeder pillar case
Body is sufficiently large, you can a cable branch box transformed, increasing the cost of electrification display on casing only needs 1000 yuan,
If cable branch box body is too small, it is difficult to installs electrification display again, need to only use the instrument improved to plug head-tail
Insulation is turned on, insertion screw rod to cable branch box carry out electrical verification, envelope line, be so not required to substantially what investment can also eliminate safety it is hidden
Suffer from.Cable branch box adds one of safety precautions equipped with electrification display equivalent to the operation maintenance to personnel.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
