Abstract
The utility model discloses an electricity-filch monitoring device with a current transformer, comprising a box body for anti-stealing electric energy, a current transformer arranged on the box body for anti-stealing electric energy, a connected cable and so on, the box body for anti-stealing electric energy comprises an upper box body and a lower box body, a plurality of locking plates and locking grooves, which are disposed according to a certain intervals, are provided on the main surface of the box body, one lateral side of the box body is provided with a cable inlet, the current transformer is embedded in the plurality of locking grooves through a plurality of grooves, the terminal of the current transformer is closed in the box body for anti-stealing electric energy, electricity can be stolen only by destroying the box body, the box body can not be recovered once destroyed, therefore, the illegal activity that the electricity is stolen by using the current transformer can be powerfully prevented.
Description
The utility model relates to a kind of current transformer anti-electricity-theft device.
At present, in power supply system, the measurement of distribution transformer output electric work is all generally adopted behind mutual inductor ratio, measure with kilowatt-hour meter again, and all bright transformer output that is contained in of instrument transformer, the shortcoming of its existence is: one, easily carried out stealing by people's line falling.Two, the modes such as current transformer that easily are replaced little no-load voltage ratio are come stealing.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of and is difficult for by the current transformer anti-electricity-theft device of stealing.
The purpose of this utility model is to realize like this, the current transformer anti-electricity-theft device is by anti-electricity-theft box body, be installed in the current transformer on the anti-electricity-theft box body, compositions such as connection cable, it is characterized in that, described anti-electricity-theft box body is divided into upper cartridge body and lower box body two parts, the upper cartridge body interarea is provided with the last box clamp of arranging at regular intervals, two adjacent clamps are formed draw-in groove, the clamp spacing is slightly larger than the recess width of current transformer, two sides are real plate, wherein a side is provided with cable inlet, end face is real plate, the top, back does not have long narrow fixed head, on described fixed head, be provided with several fixing holes, middle and lower part, back and bottom surface hollow, the interarea of described lower box body is provided with and the corresponding box clamp down of upper cartridge body interarea, the bottom surface is real plate, the back is that real plate and top are provided with and corresponding several fastener holes of the long narrow fixed head in upper cartridge body back, end face, two sides hollow, fastening bolt is equipped with on top, back at anti-electricity-theft box body, be connected with seal wire between fastening bolt, the two ends of seal wire is provided with the lead sealing piece, and described current transformer is stuck in the draw-in groove by groove, the instrument transformer terminals are enclosed in the box body, and connection cable penetrates cable inlet and links to each other with terminals.
Because the utility model current transformer anti-electricity-theft device, the terminals of current transformer are enclosed in the anti-electricity-theft box body, have only that box body is destroyed could stealing, and box body in case destroy just can not restore, this utilizes current transformer to carry out the illegal activities of stealing with regard to having prevented effectively.
