Problems solved by technology

[0003] However, with the improvement of power supply reliability, power transmission live work is becoming more and more indispensable. At present, power transmission live work (especially ultra-high voltage live work) is facing a problem: there are various types of poles and towers, live work tools do not match, and the operation is difficult. The risk factor is high, which is unfavorable to the development trend of live work, which is the technical problem above. A general-purpose live work dummy device for transmission lines is now proposed.

Embodiment 1

[0029] Embodiment one: refer to Figure 1-Figure 9 , a side-phase dummy load device in a general-purpose live-work dummy load device for transmission lines, including a dummy load 1, which is divided into two pieces by the left side of the dummy load 1 to wrap the tightening screw 3, and at the same time after the bifurcation The dummy load 1 passes through the locking structure, and when tightening or loosening the tightening screw rod 3, the locking structure is tightened or loosened to realize the release of the dummy load 1 pair of tightening screw rod 3 Control, and the tightening screw 3 is provided with a ratchet wrench 2 at one end of the top of the dummy 1, through the ratchet wrench 2, the tightening wrench 3 can be quickly reciprocated, and then the outer ring of the screw rod connector 4 can be insulated Suspender 5 stretches out or retracts the insulating suspender 5 at the bottom under the rotation action of tightening screw rod 3, and the end of insulating suspe...

Embodiment 2

[0030] Embodiment two: refer to Figure 1-Figure 9 , on the basis of Embodiment 1, a middle-phase dummy load device in a general-purpose live-work dummy load device for transmission lines, the bottom surface of the dummy load 1 is provided with an adjustable support rod base 13, and the adjustable support rod base 13 There are two adjustable support rods 14 hinged at the bottom, through the adjustable support rod base 13 and the two adjustable support rods 14, the two can be adjusted, and the angle steel can be better grasped after the length is adjusted, which can be adjusted An angle steel fixture 10 is installed on one end of the support rod 14 away from the adjustable support rod base 13, the vertical section of the wire hook 6 becomes a "C" shape, the surface of the cross arm angle steel 9 is provided with a threaded hole, and the inside of the threaded hole is sleeved with a bolt. The insulator string 8 and the cross arm angle steel 9 are fixedly connected by bolts, and ...

Abstract

The invention discloses a universal live-line work false carrying device for a power transmission line, relates to the field of universal live-line work false carrying equipment, and provides the following scheme aiming at the problems that an existing universal live-line work tool is large in work difficulty, low in safety coefficient and the like, the universal live-line work false carrying device comprises a false carrying device, and the left side of the false carrying device is sleeved with a tightening lead screw; a ratchet wrench is arranged at the end, located on the top of the false arm, of the tightening lead screw. The universal hot-line work dummy arm device provided by the invention has the practical characteristics of a universal dummy arm, is small in size, light in weight and simple and convenient to mount, can mount the dummy arm within a few minutes no matter which tower type is in hot-line work of a power transmission line, can realize the effect of integrating multiple lines and multiple tower types, and is high in practicability. And moreover, the false arm can be moved from the original operation at the bottom of the cross arm to the operation on the cross arm surface, so that the operation safety distance is larger, the operation is more convenient, and the safety coefficient is greatly improved.

Description

technical field [0001] The invention relates to the field of general-purpose dummy load equipment for live work, in particular to a general-purpose dummy load device for live work on transmission lines. Background technique [0002] Live work refers to a method of maintenance and testing on high-voltage electrical equipment without power failure. Electrical equipment needs frequent testing, inspection and maintenance during long-term operation. Live work is an effective measure to avoid maintenance blackouts and ensure normal power supply. The content of the operation can be divided into several aspects such as live test, live inspection and live maintenance. The objects of live work include electrical equipment in power plants and substations, overhead transmission lines, power distribution lines and power distribution equipment. The main items of live work are: : Live replacement of line tower insulators, cleaning and replacement of insulators, flushing insulators with wat...
