Problems solved by technology

[0002] The phase sequence plate is used to identify the phase sequence of the distribution line. The phase sequence plate installed on the distribution line is basically a label plate made of metal or plastic. Yellow, green, red, and black represent A, B, and C respectively. , N phase difference, fixed on the cross arm by glue or screw tightening, the above-mentioned phase sequence plate is not very clear after being hung for a year and a half after being exposed to wind and sun; some brands hang in disorder On the crosspiece, it is extremely irregular; it is difficult to accurately distinguish the double (multiple) circuits on the same pole, and the corners of the line; it is difficult to determine the fault phase when searching for faults at night

Embodiment Construction

[0031] As shown in the figure, a distribution line phase sequence card includes a fixed block 1 and a lock block 2. The lock block 2 includes a hinged end 3 and a snap-in end 4. The hinged end 3 is hingedly mounted on the fixed block 1 and snapped The end 4 is snap-fitted with the fixed block 1, and the clamping mechanism 5 that can press the pipeline on the inner wall of the lock block 2 is installed on the lock block 2, and the bottom end of the fixed block 1 is provided with an identifiable mark 6 , after the fixed block and the locking block are snapped and connected, a closed mechanism is formed to connect the pipeline in the closed area, thereby realizing the connection between the entire device and the pipeline, and the snap-fitting of the snap-fit ​​end and the fixed block is used for the opening and closing of the locking block , the hinged end is used for the flexible connection between the lock block and the fixed block. When in use, the pipeline is sleeved between t...

Abstract

The invention discloses a distribution line phase sequence card which includes a fixed block and a locking block. The locking block includes a hinged end and a clamping end. The hinged end is installed on the fixed block in a hinged mode, the clamping end and the fixed block are clamped and matched, a clamping mechanism for pressing a pipeline on the inner wall of the locking block is mounted on the locking block, and the bottom end of the fixed block is provided with an identifiable identifier. The distribution line phase sequence card is convenient to use, is installed stably, is long in service life and has various functions. The distribution line phase sequence card can adapt well to pipelines with complicated lines and placed at high places, and the use effect at night is good.

Description

technical field [0001] The invention relates to a phase sequence plate of a power distribution line. Background technique [0002] The phase sequence plate is used to identify the phase sequence of the distribution line. The phase sequence plate installed on the distribution line is basically a label plate made of metal or plastic. Yellow, green, red, and black represent A, B, and C respectively. , N phase difference, fixed on the cross arm by glue or screw tightening, the above-mentioned phase sequence plate is not very clear after being hung for a year and a half after being exposed to wind and sun; some brands hang in disorder On the crosspiece, it is extremely irregular; it is difficult to accurately distinguish the double (multiple) circuit lines on the same pole, and the corners of the line; it is difficult to determine the fault phase when troubleshooting at night. Contents of the invention [0003] The present invention provides a distribution line phase sequence ...
