Puncture type electric maintenance safety discharge fitting structure based on fault warning

Abstract

The invention discloses a puncture type electric maintenance safety discharge fitting structure based on fault warning. The puncture type electric maintenance safety discharge fitting structure basedon fault warning comprises a power transmission wire clamp, a fixed bolt and a base, wherein the fixed bolt is fixedly connected to the side end of the power transmission wire clamp, and the power transmission wire clamp is arranged above the base; the base is arranged below the fixed bolt; according to the structure, the fitting on an overhead line is monitored by utilizing the provided device with the fault warning function, the power transmission wire is punctured through a puncture needle and is in contact with a conductor of the puncture needle, so that partial current is transmitted to acontroller through a conductive plate, and a fault warning lamp can be powered on to be lighten up; and when the fitting cracks caused by fault due to external environment, the current passing through the puncture needle changes, the controller is powered off, the fault warning lamp is turned off, and therefore an overhaul personnel can be reminded that the fitting on the overhead line is damaged, so that the maintenance process can be timely carried out, the loss efficiency of the line fitting is reduced, and meanwhile, the problem of line faults is avoided, the economic loss caused by the line faults is effectively reduced, and the stable and reliable operation of the power grid is ensured.

Description

technical field [0001] The invention relates to the field of electric power maintenance, in particular to a puncture-type electric power maintenance safety discharge fitting structure based on fault warning. Background technique [0002] Fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical and electrical loads or play a certain protective role. They have the functions of supporting, fastening, connecting, and protecting transmission lines and lightning protection lines. The power fittings used on power lines are related to the safety of wires or towers. If one is damaged, it may cause line failure and have a certain impact on the safe discharge of the line. [0003] At present, the existing hardware structure has the following disadvantages: [0004] On overhead power lines, under the long-term action of the external environment, the contact surface of the fittings will be subject to friction and the material of ...

Problems solved by technology

[0004] On overhead power lines, under the long-term action of the external environment, the contact surface of the fittings will be subject to friction and the material of the fittings will gradually reduce until the load it bears exceeds its breaking load. Since most of the fittings are made of iron or aluminum, they are affected by the external environment. Affected, corrosion or rust is prone to occur, causing slow oxidation on the surface, causing hardware fracture and failure, and it is difficult for maintenance personnel to find and repair in time, resulting in line failure and large economic losses
