Description

Technical Field

[0001] The invention relates to the technical field of equipment, in particular to a grinding wiring device for loop resistance testing. Background Art

[0002] Loop resistance is a parameter that indicates whether the connection of a conductive loop is good or not. It is usually used to characterize the contact condition of each connection point in the conductive loop. If the loop resistance exceeds the specified value, it may mean that a certain connection point in the conductive loop has poor contact. When running at high current, poor contact will cause local temperature rise, and in severe cases may cause oxidation and burning. Therefore, it is particularly important for equipment used for high current operation.

[0003] The loop resistor is usually installed on the top of the insulating rod. In order to ensure the safety of the transmission line, the power workers need to test the loop resistor regularly.
