Embodiment
[0017] figure 1 , figure 2 , image 3 An example of the invention is given. refer to figure 1 , figure 2 , image 3 Make the invention. The substation cable trench cable discharge spotlight alarm detection device includes a cylinder body 1, which is characterized in that: a condenser lens 2 is embedded in the lower opening of the cylinder body 1, a sound alarm 3 is embedded in the upper opening of the cylinder body 1, and the cylinder body A photoelectric conversion module 4 is arranged in the cavity of 1, and the photoelectric conversion module 4 is connected to the sound alarm 3 through a wire 5; When a short-circuit fault occurs in the high-voltage cable, the generated arc light is condensed by the condensing lens 2 and irradiated on the photoelectric conversion module 4. The photoelectric conversion module 4 converts the condensed signal into an electrical signal, and then transmits it to the sound through the wire 5. The alarm 3 and the sound alarm 3 can report t...

The invention discloses a condensation alarm detection device for cable discharge of a cable trench of a transformer substation. The condensation alarm detection device comprises a barrel body; the condensation alarm detection device is characterized in that a condensation lens is embedded into a lower opening of the barrel body, a sound alarm is embedded into an upper opening of the barrel body, and a photoelectric conversion module is arranged in a cavity of the barrel body and connected with the sound alarm through a lead wire; the center of the condensation lens and the center of the photoelectric conversion module are arranged on one axis; a long-strip-shaped magnetic block is arranged at an upper end of the barrel body and an insulated guide wire penetrates a slide hole of the long-strip-shaped magnetic block. According to the detection device, a principle that arc light during cable short circuit is condensed and converted into an alarm signal is adopted, a cover plate used for isolating the cable trench is adopted at the same time, and the detection device is pulled through magnetic suction force to move along a cable, so that the detection device is simple in structure and easy to implement and can quickly find a cable short circuit position; the cover plate of the cable trench is opened in an accurate position, so that the labor intensity is greatly reduced, the labor efficiency is improved, and the detection device can be specially used for detecting cable faults of the cable trench of the transformer substation.
Description
technical field [0001] The invention relates to an improvement of a cable partial discharge detection device, which belongs to the technical field of substation cable trench cable detection, in particular to a substation cable trench cable discharge spotlight alarm detection device. Background technique [0002] Substation cables are laid in underground cable trenches and covered with cover plates. Due to the complex situation in the cable trench, the cables often break down. When the cable line fails and trips, the operating personnel need to check the equipment in the substation. If the cable fault occurs in the substation, because the cable is in the underground cable trench and covered by a heavy cable trench cover, it is difficult for the operator to observe it in place. In addition, the probability of the cable fault occurring in the cable trench in the substation is relatively small, and it is easier to be ignored. . At present, manual methods are usually used to fi...
