Description
Technical Field
The invention belongs to the field of bypass operation, and particularly relates to a cable leading-in wire fixing device for bypass operation.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The bypass operation is mainly suitable for overhauling overhead conductors, ring main units, cable lines, transformers and temporarily taking electricity from the overhead lines or the ring main units to the overhead lines. Aiming at overhead conductor maintenance, pole tower replacement and the like, loads are transferred to a bypass system through a bypass load switch and a bypass cable, the power-off maintenance of an overhead line to be detected is realized, the standardized operation flow of the overhead line sign is maintained according to the comprehensive uninterrupted operation method of the 10kV distribution line, and the bypass cable is required to be connected to the overhead conductor. The tools that need to be used include insulating gloves, electroscope, insulating action bars, quick plug bypass cable connector, bypass cable terminal, bypass load switch, insulating cross arm etc. instrument. The live-line work of the bypass cable is applied to the work that an original operation line needs a disconnection process in the live-line maintenance process or the work that a power supply needs to be changed, and a set of temporary power supply bypass system is built by using the bypass cable to realize the maintenance of a disconnection point.
In the process of the whole bypass operation, whether the bypass system for temporary power supply can be successfully built directly influences whether the bypass operation can be carried out or not, and the maintenance work can not be carried out in a live working mode without the bypass system. The bypass cable installation is firstly provided with the insulating cross arm, and then the bypass cable is fixed on the insulating cross arm. There are two main ways to connect the cable lead-up to the overhead conductor: firstly, the cable head is transferred to the installation place by personnel on the wire pole by using the insulating operating rod. The method increases the operation tasks of operators on the line pole, consumes the physical strength of the operators, and simultaneously, electric shock is possibly caused by insufficient insulation distance between the cable head and the overhead line in the transmission process, so that personal casualty accidents are caused, and the method is not advisable; and secondly, the cable is extracted up and down through the bucket arm vehicle to realize the installation. When the power-taking overhead line meets the same-tower double-circuit line, the cable head of the bypass cable freely swings and mistakenly touches the same-tower circuit, so that potential safety hazards can appear and personal electric shock accidents can be caused. Meanwhile, the freely falling bypass cable joint increases the workload of operators in the hopper and reduces the working efficiency.
For example, chinese patent publication No. CN203747339U discloses an insulating bracket on a bypass operation column, which includes a first anchor ear and a second anchor ear having arc-shaped semicircular structures, and the first anchor ear and the second anchor ear can be matched to form a ring. The middle part of first staple bolt is equipped with the connecting pipe, and the one end of insulating tube is passed through connecting pipe and first staple bolt fixed connection, is equipped with cable fixing clamp on the insulating tube. The middle of the second hoop is provided with a support plate, and the extending direction of the support plate is vertical to the extending direction of the second hoop. The first staple bolt and the second staple bolt inboard all are equipped with the recess, and inside is equipped with anti-skidding rubber pad. In the use, connect the pole through first staple bolt and second staple bolt, fix insulating support safe and reliable on the bypass operation post on the pole, the cable fixation clamp on the insulating tube can be to joining in marriage the hanging wire or the drainage line that reliable fixed of net live working in-process and carry out interim fixing this moment, makes going on of live working ability safety fast more.
However, the above-mentioned insulating bracket on the bypass operation column can only be used for temporarily fixing a lead or a drainage wire, and the functional object is single, and the work flow of the bypass operation cannot be simplified, the installation time of the bypass cable is reduced, and the use is limited.
Disclosure of Invention
The cable head is fixed on the overhead line, so that the installation flow of the bypass operation cable lead-up line is simplified, the overall installation time is shortened, and meanwhile, the cable lead-up line cannot be mistakenly bumped down to a same tower line due to free swing in the whole installation process, potential safety hazards are generated, and personal and power grid losses are caused.
