Abstract
The utility model discloses a high-voltage cable distribution box, belonging to the technical field of cable distribution devices. The high-voltage cable distribution box comprises a box body, a cable is arranged in the box body on which an electrified display device is arranged, one end of the electrified display device is connected with a detector, and the other end of the electrified display device is grounded. When the cable in the box body is electrified, the detector detects potential, and the electrified display device makes corresponding display according to the detection result of the detector, so as to give an alarm to personnel and avoid danger.
Description
Technical field
The utility model belongs to cable distribution device technique field, especially relates to a kind of High-Voltage Cable Branching Case.
Background technology
High-Voltage Cable Branching Case is a kind of electric equipment of investing as outdoor cable tap, raising power supply reliability, saving in the electric power system, is widely used in places such as avenue, residential quarters, skyscraper, park, school.
The casing of High-Voltage Cable Branching Case is provided with case lid, is provided with cable in the casing.Have high voltage when during operate as normal work in the cable junction, if, electric shock accidents may take place at this time opening case lid.And sometimes in order to overhaul, must case lid be opened, if it is whether open the preceding casing inner cable of being not sure of charged, very dangerous.
Summary of the invention
The utility model provides a kind of High-Voltage Cable Branching Case to deficiency of the prior art, can show whether the casing inner cable is charged.
For solving the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of High-Voltage Cable Branching Case; Comprise casing, be provided with cable in the said casing, said casing is provided with charged display unit; Said charged display unit one end links to each other other end ground connection with checkout gear.When switching in the casing inner cable, checkout gear detects voltage, and charged then display unit is made corresponding demonstration according to the testing result of checkout gear.
In the technique scheme, preferred, said charged display unit comprises dial plate and indicator light, and said dial plate is fixed on the top of said casing, and said indicator light is fixed in the said dial plate.When checkout gear detects cable when charged, indicator light sends light.
In the last technical scheme, preferred, said checkout gear comprises a sheet metal, and said sheet metal is near said cable.What feed in the cable is generally alternating current, sheet metal near cable after, and form an electric capacity between the cable, and electric capacity is indirect current, so as long as in the cable electric current is arranged, sheet metal just can make indicator light luminous with current delivery to indicator light.
The beneficial effect of the utility model is: when switching in the casing inner cable, checkout gear detects current potential, and charged then display unit is made corresponding demonstration according to the testing result of checkout gear, and personnel are made caution, avoids occurring dangerous.
