Test rod for high-voltage nuclear phase instrument

Abstract

The invention belongs to the technical field of electric nuclear phase, and particularly relates to a test rod for a high-voltage nuclear phase instrument, which comprises the test rod and a contact electrode arranged at one end of the test rod, wherein the test rod comprises an inner rod, a middle rod and an outer rod; the inner rod, the middle rod and the outer rod are in nested connection witheach other; the top of the outer rod is connected with the contact electrode; a handle is arranged at the one end of the inner rod, far away from the contact electrode; a rebound spring is arranged ina central hole of the test rod, the one end of the rebound spring is fixed on the outer rod, the other end of the rebound spring is fixed on the handle, the rebound spring sleeves a fixed rod, the one end of the fixed rod is fixed on the top of the outer rod, the other end of the fixed rod is provided with a fixed round table, and the handle is internally provided with a locking mechanism matchedwith the fixed round table. By the adoption of the test rod for the high-voltage nuclear phase instrument, the test rod of an existing nuclear phase instrument is improved, and the test rod of the nuclear phase instrument becomes a structure capable of being automatically placed, so that the operation is more convenient and faster, meanwhile, a carrying amount of equipment is reduced, and construction by electric power engineering personnel is facilitated.

Description

technical field [0001] The invention belongs to the technical field of electric power nuclear phase, and in particular relates to a test rod for a high-voltage nuclear phase instrument. Background technique [0002] With the development of my country's economy, the demand for electricity continues to grow. While the capacity of the power grid continues to increase, there are higher requirements for the stability of the power system operation. Under the background of building a strong smart grid and advocating green energy, clean energy is gradually replacing fossil energy, and new substations are constantly being built. Newly built substations and rebuilt transmission lines must undergo a phase verification test before they are put into use to ensure that the phase sequence is correct. If a short-circuit accident is caused by grid connection and ring closure, the electrical equipment will be damaged in the slightest, and the original stability and balance of the power grid...

AI Technical Summary

Problems solved by technology

[0004] Because the high-voltage line is relatively high, it is generally necessary for the staff to assemble at least two test rods before measurement. At the same time, due to the need for assembly, the entire high-voltage nuclear phase equipment needs to carry more equipment, which is not conducive to the rapid operation of electric engineering personnel. construction work
