Technical Field

The invention relates to the technical field of relay protection and high-voltage tests, in particular to a charge and discharge type wire hanging rod.

Background

Before formal live operation, current and voltage transformers need to carry out 'polarity' and 'transformation ratio' calibration work of relay protection profession and test work such as high-voltage professional high-voltage withstand voltage, insulation and the like, primary side terminals of the transformers are connected with a high-voltage primary bus of a transformer substation, when some electrical performance experiments are carried out, test wires need to be hung on high-altitude high-voltage test terminals with the height of more than 5 meters, and at the moment, a special hanging bar with the length of more than 5 meters is needed.

The traditional wire hanging method is characterized in that insulating pull rods of power transformation operators are utilized to splice a temporary wire hanging rod with the length exceeding 5 meters in a section mode. Time and labor are wasted when the utility model is used, and the wire hanging effect is not ideal.

Even if the insulation pull rod of a power transformation operator is not used as a wire hanging tool, the insulation pull rod is specially equipped, and the traditional insulation pull rod is very long in length and inconvenient to place when being carried in a minibus of a team, so that the insulation pull rod needs to be assembled and connected in a section, time and labor are wasted, and a lot of inconvenience is brought to experimental work of the team. Therefore, how to develop a special high-altitude wire hanging rod which can be placed in a small backpack and is more than five meters long is a problem to be solved at present.
