Description
Technical field
The utility model relates to system for distribution network of power field, particularly relates to a kind of cable branch box of tape jam measuring ability.
Background technology
Power cable is mainly used in the electric energy transmitted and distribution power plant sends, and the double fastening means done between all kinds of electric equipment.Compared to overhead transmission line, cable has that floor space is little, power supply reliability is high, safer to the person, run simply, not by advantages such as ectocine, maintenance workload are little.But, because cable is buried in underground, when cable breaks down, be difficult to fault Timeliness coverage, and then can not restore electricity in time to power supply interrupted district.
The effect of current cable branch box carries out tap or switching to cable.Cable branch box is widely used in open air, and along with the progress of technology, the cable branch box of present belt switch also constantly increases, but current cable branch box also exposes following problem:
(1) cable tap or adapter are positioned at cable branch box, because cable branch box only plays cable branch or switching effect, when cable breaks down time, cannot identify failure cable, must be identified by the fault phase of manual method to cable, inefficiency.
(2) fault detector has been installed additional in cable branch box in Ye You electric company at present, and namely below each cable end, installed cable fault indicator, when a certain of cable is broken down mutually, the indicator light of fault detector can brighten.But this way also needs manually to open cable branch box, then carry out fault detector check work.Due in the middle of actual motion, cable branch box surface may produce induction electrostatic, can injure electric power patrolman time serious, therefore also there is certain danger to the operation of cable branch box.
What above problem all can incur loss through delay cable fault and cable fault phase searches the time, thus this extends the service restoration time of power supply interrupted district, is very disadvantageous to raising power supply reliability.
Utility model content
The purpose of this utility model is exactly to solve the problem, provide a kind of cable branch box of tape jam measuring ability, not only possesses cable branch basic function, and can automatic fault detection cable and cable fault phase, and be directly presented at casing outside, facilitate distribution network failure to investigate personnel to carry out while failure cable searches, improve power distribution network accident search capacity and power supply reliability.
To achieve these goals, the utility model adopts following technical scheme:
A cable branch box for tape jam measuring ability, comprising: casing;
Be provided with cable branch equipment in described casing, be provided with Cable fault examination equipment in described casing, described Cable fault examination equipment and control device connects, and described controller is connected with display screen; Described display screen is arranged on the outer wall of casing
The top of described casing is provided with solar power plant, and described solar power plant is that controller is powered.
The outside of described display screen is provided with polymethyl methacrylate protective cover.
Described controller is connected with malfunction indicator lamp, and described malfunction indicator lamp is located on cabinet exterior.
Often organize cable and be furnished with a display screen, every phase cable is furnished with a set of Cable fault examination equipment, and each display screen can show the cable fault information of corresponding group, comprises cable line title, fault phase, time of failure and fault current size.
The inwall of described casing is provided with reset button.
The beneficial effects of the utility model are:
Traditional cable branch box and fault detector are combined, and at casing arranged outside fault display device, when cable breaks down, Electric Power Patrol personnel are not needed to open cable branch box, can cable fault scenario directly outside casing in inspection box, not only increase the search efficiency to cable fault, and make Electric Power Patrol personnel avoid contact feeder pillar casing.While protecting Electric Power Patrol personnel, improve the power supply reliability of power distribution network.Controller adopts solar power generation to power, and takes full advantage of new forms of energy.

Fig. 2 is casing overall schematic figure.
Fig. 3 is the utility model exterior display screen schematic diagram.
Wherein, 1. display screen, 2. wire, 3. cable, 4. Cable fault examination equipment, 5. busbar, 6. controller, 7. solar power plant, 8. casing.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As Figure 1-3, a kind of cable branch box of tape jam measuring ability, comprising: casing 8; Be provided with cable branch equipment busbar 5 in casing 8, for being separated by cable 3, be provided with Cable fault examination equipment 4 in casing 8, Cable fault examination equipment 4 is current sensor, and Cable fault examination equipment 4 is connected with controller 6, and controller 6 is connected with display screen 1; When detect reach the fault curre of setting by the electric current of cable time, controller can trigger display screen display fault message; Display screen 1 is arranged on the outer wall of casing 8.The top of casing 8 is provided with solar power plant 7, and solar power plant 7 is powered for controller 6.
Often organize cable 3 and be furnished with a display screen 1, every phase cable 3 is furnished with a set of Cable fault examination equipment 4, and each display screen 1 can show the cable fault information of corresponding group, comprises cable line title, fault phase, time of failure and fault current size.
Controller 6 is connected with malfunction indicator lamp, and malfunction indicator lamp is located on casing 8 outer wall, is positioned at display screen 1 side; Malfunction indicator lamp lights, and facilitates Electric Power Patrol personnel to carry out trouble shoot, after Electric Power Patrol personnel find failure cable, can not open cable branch box, direct read failure cable and fault separate, then notify electric power first-aid class carry out breakdown repair.The outside of display screen 1 is provided with polymethyl methacrylate protective cover, can prevent rainwater from immersing and artificial destruction.
The inwall of casing 8 is provided with reset button.Reset button is inside cable branch box, and the electric power first-aid personnel only possessing maintenance qualification open cable branch box and to this system reset, could ensure that this system can not be touched by non-electricity personnel.
Under normal circumstances, the cable branch box of this tape jam measuring ability only does cable branch and switching use.In non-faulting situation, Cable fault examination systems axiol-ogy, less than failure cable, does not send fault-signal.When the electric current by cable 3 reaches the fault curre of setting, the display screen 1 being positioned at cable branch box outside starts, and shows fault phase, the fault current of cable 3 and points out with light flash.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection range; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection range of the present utility model.
