Description

Technical Field

[0001] The present invention relates to the technical field of spacer bars, and in particular to an installation device for preventing spacer bars from falling off. Background Art

[0002] In recent years, Henan Power Grid Company has been committed to improving the safety of its distribution network overhead lines. It has implemented various measures to enhance power supply reliability and mitigate the impact of severe weather on the safe operation of distribution lines. As a result, the number of medium-voltage overhead line failures has decreased annually. However, frequent severe convective weather, resulting in high-frequency, wind-induced discharge faults on large-span lines, continues to be a leading cause of distribution network failures at Henan Power Grid Company.

[0003] The essence of the large-span windage problem is that under the influence of strong winds, the conductors dance, causing the phase-to-phase distance to decrease. The reduced insulation distance causes the line to discharge to surrounding objects or between phases. The impact is particularly severe in windy and rainy weather. Rainwater attached to the conductors will gradually form intermittent water flows according to changes in wind direction. When the intermittent water flow formed by rainwater is in the same direction as the discharge flashover path, it will cause the discharge voltage in the air gap to drop, ultimately causing windage failure of the distribution network line. At the same time, in some areas with relatively unique terrain, the wind force at the wind outlet and wind duct location is often more concentrated, making the micro-meteorological characteristics of the area prone to windage failure of distribution lines. In particular, due to the mountainous terrain, the relatively high pole tower design and the large altitude difference, the conductors are required to withstand higher wind speeds. When the wind speed exceeds the standard that the conductor can withstand, it will cause the pole tower conductor insulator to tilt, and ultimately cause windage flashover failure.

[0004] Therefore, it is necessary to carry out research on key technologies for installing interphase spacers in large-span lines of 10kV distribution networks in Henan Province and the development and application of its devices. The research focuses on the structural characteristics of the hardware used to fix the end of the spacer bar, its fastening method and fastening system, so as to cooperate with the installation device to complete the installation of the spacer bar and hardware at the specified position; the research also focuses on the transmission method of the spacer bar and its connecting hardware from the release position to the specified installation position, the system structure of the installation device and the key technologies for driving and controlling it, as well as the return of the installation device from the specified installation position to the release position; the research also focuses on the technical scheme for moving the spacer bar installation device up and down the pole and the auxiliary system for operating and controlling the installation device; the practical application of interphase spacers for distribution lines is completed, and the effectiveness of the installation scheme before and after the installation of the interphase spacers is evaluated; the compilation of a specification for the installation scheme for interphase spacers in large-span lines can provide support for the installation of spacers in large-span distribution lines in Henan Province, reduce gap grounding faults, phase-to-phase short circuit faults, overcurrent protection tripping and other faults caused by windage discharge, improve the safe and stable operation level of the distribution network in Henan Province, and contribute to the construction of a reliable and strong power grid.

[0049] In the initial state, the control rod 54 is lifted by the spring at the bottom thereof, so that the circuit of the electromagnet 59 is closed, and the electromagnet 59 generates magnetism; the two fixing parts 5 with the spacer rod parts 6 are placed on the corresponding base parts 4 respectively, so that the fixed horizontal plate 51 is located in the horizontal groove 47 and the lower fixed plate 52 is located in the longitudinal groove 45. At this time, the electromagnet 59 is opposite to the iron block on the inner side of the vertical support plate 46, and absorbs the iron block, fixes the upper fixing plate 57 on the inner side of the vertical support plate 46, and fixes the spacer rod part 6 between the two base parts 4 through the fixing part 5; control the drone 1 to make it fly a circle at the location where the spacer rod part 6 needs to be installed, and the information of the laser sensor and the visual sensor are integrated to build a map, and the map information is sent back to the ground station. The operator then confirms the installation point based on the map information on the ground, and finally the drone 1 is based on The installation point information of the ground station is controlled by the onboard computer, and the drone autonomously navigates to a suitable position, hovers below the required installation position, and places the connecting shaft 39 directly above the wire 2. The motor in the sleeve 33 is started, and the motor drives the vertical plate 34 to rotate around the rotating shaft 32, so that the connecting shaft 39 is above the wire 2, reducing the flight altitude of the drone 1, and hanging the connecting shaft 39 on the wire 2. The telescopic cylinder in the first card body 37 is remotely controlled to start, and the piston rod of the telescopic cylinder retracts, pulling the second card body 38 and the connecting shaft 39 toward the first card body 37 through the fixing frame 30, so that the connecting shaft 39 slides into the first card body 37, reducing the distance between the first card body 37 and the second card body 38, and the wire is stuck in it. The drone 1 is hung on the wire 2, so that the drone 1 and the wire 2 remain relatively stationary, which is convenient for installing the spacer rod part 6;Through remote operation, the two telescopic cylinders 41 are started at the same time, and the piston rod of the telescopic cylinder 41 extends out, and the fixing part 5 and the spacer part 6 are lifted to the wire 2 through the base part 4. When the wire 2 is located in the corresponding lower fixing groove 53 and the control rod 54 is pressed downward, the spring under the control rod 54 contracts, and the control rod 54 moves downward, disconnecting the circuit of the electromagnet 59, and the magnetism of the electromagnet 59 disappears. The electromagnet 59 no longer attracts the iron block on the inside of the vertical support plate 46, and the upper fixed plate 57 turns to the lower fixed plate 52 under the action of the torsion spring at the connecting shaft 55, so that the upper fixing groove 58 is located above the lower fixing groove 53, forming a complete circular hole, and the wire 2 is stuck therein, and the telescopic cylinder 41 is manipulated to retract its piston rod, thereby lowering the height of the base part 4 and leaving the fixing part 5 and the spacer part 6. The drone 1 is manipulated to fly above the fixing part 5, and the mechanical arm under the drone 1 is extended, and the screwdriver under the mechanical arm is used to fix the upper fixing part The bolts on the plate 57 are screwed into the screw holes 56, fixing the upper fixing plate 57 to the lower fixing plate 52, tightly clamping the wire 2. In the same way, the upper fixing plate 57 of the fixing portion 5 at the other end of the spacer bar portion 6 is fixed to the lower fixing plate 52, clamping the other wire 2, and fixing the spacer bar portion 6 between the two wires 2. Similarly, the spacer bar portion 6 can be installed on any wire 2 that needs to be installed. After installation is completed, the telescopic cylinder in the first card body 37 is remotely controlled. The telescopic cylinder piston rod extends, pushing the second card body 38 and the connecting shaft 39 away from the first card body 37, causing the connecting shaft 39 to slide out of the first card body 37, increasing the distance between the first card body 37 and the second card body 38. The wire 2 is disengaged from between the first card body 37 and the second card body 38, raising the height of the drone 1. The motor is then operated to drive the vertical plate 34 to rotate in the opposite direction around the rotating shaft 32, causing the connecting shaft 39 to leave the wire 2, and the drone 1 performs the one-key return mission.
