Lightning arrester device and regulating method for detecting automatic balance of direct current supply of transformer substations

Abstract

The invention discloses a lightning arrester device and a regulating method for detecting the automatic balance of direct current supply of transformer substations. The lightning arrester device comprises a hollow barrel. The hollow barrel is arranged at the upper end of an insulating telescopic rod and is perpendicular to the insulating telescopic rod, an annular magnet is arranged on a side of the barrel, the size of the annular magnet is matched with the diameter of a hole of the barrel, a motor is arranged in the barrel via a slide mechanism, a turntable sleeves an end of a rotary shaft of the motor, a conductive brush is arranged on the outer side of the turntable, a turntable tightness compression regulating mechanism is arranged in the barrel, and an elastic conductive sheet which is connected with the rotary shaft of the motor is arranged in the barrel. The lightning arrester device and the regulating method have the advantages that wires can be shifted onto metal components of a lightning arrester only by a single person in a time-saving and labor-saving manner and are in excellent contact with the metal components, the person does not need to climb to clean corrosion substances of the metal components, accordingly, the labor intensity is extremely low, more importantly, an integral wiring procedure can be completed by the single person in one minute, and the wiring efficiency is extremely high.

Description

technical field [0001] The invention belongs to the technical field of measurement and detection equipment for lightning arresters in substations, and in particular relates to an automatic balance detection lightning arrester device and adjustment method for DC power supply in substations. Background technique [0002] The function of the arrester in the overhead line is mainly to release overvoltage such as lightning and protect the power grid and electrical equipment from instantaneous overvoltage hazards, thereby ensuring the safe and stable operation of transmission lines and electrical equipment. [0003] At present, 35kV, 66kV, 110kV, 220kV, and 550kV voltage level surge arresters are installed outdoors. Due to long-term erosion by moisture, rain, snow, and corrosion, the metal parts are mostly iron, which is easy to rust and is extremely difficult to clean.

AI Technical Summary

Problems solved by technology

[0003] At present, 35kV, 66kV, 110kV, 220kV, and 550kV voltage level surge arresters are installed outdoors. Due to long-term erosion by moisture, rain, snow, corrosion, etc., most of the metal parts are made of iron, which is easy to rust and is extremely difficult to clean.

When measuring the conductance current of the arrester, it is difficult to accurately measure the conductance current of the arrester due to the influence of rust, which leads to poor contact, which brings inconvenience to the test work, and even causes misjudgment

The traditional test method has the following disadvantages: 1) It requires staff to climb up to operate and clean up the rusty metal parts. The operation requirements are relatively high, and the labor intensity is very high and the efficiency is low.

2) At least two people are required to bind the wires to the metal parts, and after cleaning, the test wires need to be bound to the metal parts. Due to the huge test current, the diameter of the wires is large and the quality of the wires is large, which is easy to cause the binding not tight enough. During operation, the binding place will heat up, or even burn the wires, which will affect the test effect and the test efficiency is extremely low
