The utility model relates to power equipment technical field, specifically disclose a kind of auxiliary shielding cover and high-voltage conductor shielding structure, high-voltage conductor shielding structure includes insulating protective tube and auxiliary shielding cover, and insulating protective tube is used to wrap high-voltage conductor;Auxiliary shielding cover is coated in the outside of insulating protective tube, and auxiliary shielding cover includes shielding main body, handle, guard plate and V-shaped plate assembly, wherein the inverted eight-character shape tightening passage formed by V-shaped plate and eight-character shape guide passage, by depressing handle drive V-shaped plate self-adapting to gather, realize the tool-free quick wrapping and disassembly of guard plate to the bottom of insulating protective tube;Shielding main body covers connection area completely, and the thickening in the middle section of protective tube is combined with shielding segmented coating design, and the creepage distance is promoted to above 150mm, and the risk of electric leakage is blocked;V-shaped plate mechanical locking and annular protrusion-groove cooperation structure ensure that shielding cover anti-vibration loosening and wind environment stability.

The application relates to a kind of spaceborne wave tube amplifier high voltage joint miniaturization butt joint methods, comprising: stripping, shaping, tin lining high voltage wire between wave tube power supply and wave tube butt joint;Cutting the length of high-voltage polyolefin heat shrinkable sleeve required, and wear on the high voltage wire;Wave tube power supply and wave tube butt joint high voltage wire is hooked together, and the total length of hooking welding spot and bare wire core is controlled at 4-5mm;Point epoxy glue on the hooking welding spot and high voltage wire core;According to the required process, use hot air gun to blow the high-voltage polyolefin heat shrinkable sleeve and solidify epoxy glue.The application realizes the miniaturization and light weight of the high voltage butt joint between the wave tube power supply and the wave tube of the spaceborne wave tube amplifier, shortens the development cycle of the product, and reduces the high voltage butt joint integration process time between the wave tube power supply and the wave tube from 72 hours to 4 hours.

The application discloses a fault detection ring suitable for extra-high voltage conductors and relates to the technical field of extra-high voltage conductor fault detection.The fault detection ring comprises an upper frame, a lower frame and a control module, the upper frame and the lower frame form a cylindrical frame, one side of the cylindrical frame is hinged, and the other side is connected through a buckle, characterized in that: a mounting box is arranged on the lower side of the cylindrical frame, the mounting box is used for accommodating the control module and a power supply assembly, and two groups of detection mechanisms are arranged in the cylindrical frame.The application is provided with the upper frame, the lower frame, a moving mechanism and the detection mechanisms, can continuously move the cylindrical frame along the direction of the conductors through the electric wheels after the device is sleeved outside the extra-high voltage conductors, drives the wrapping shell to rotate through the first motor, makes the detection array circumferentially scan around the conductors, thereby continuously detects the local magnetic field distortion of the conductors, and has the advantage that the continuous detection capacity of the existing conductor detection device can be improved.

This invention discloses a split-type capacitor-driven power supply device, aiming to solve the problems of large size and ferroresonance risk of traditional electromagnetic PTs. The device includes physically separated high-voltage and low-voltage modules connected by cables. The high-voltage module is connected to a high-voltage conductor and couples electrical energy through a capacitor-driven energy extraction unit for preliminary conversion; the low-voltage module receives this energy and converts it into stable DC power output. This invention achieves complete electrical isolation between the high and low voltage sides through physical separation, eliminating the risk of ferroresonance and offering advantages such as high safety, small size, and high reliability.
