Description
Technical field
This utility model is related to a kind of detection part device of track traffic, and in particular to a kind of insulation of locomotive roof
Sub- detection means, for being detected to locomotive roof insulator dielectric performance in good time, category track traffic components/devices monitoring control
Technical field processed.
Background technology
In recent years, China's high ferro, heavy loading locomotive are achieved and are greatly developed, and electric railway total line length holds a safe lead which
He is national.
Used as electric railway, the onboard electrical part of locomotive is one of of paramount importance part of locomotive, locomotive vehicle-mounted electricity
The insulation of gas part is good most important with bad, and the insulation degradation of its part directly results in the reduction of safety coefficient, conevying efficiency.Than
Such as, the current electric railway service time be up to decades, even if high ferro has also run the several years such as military wide circuit；And as line
The locomotive vehicle-mounted electrical system of road operation is the key system components that locomotive electrical gasification drives, and these electrical system components are also all slow
Slow-motion enters aging period, at this moment needs constantly to electric apparatus mounted on vehicle, especially pantograph and top insulation, in-car inversion
The important electric components such as device, mobile transformer, master controller and motor carry out insulating properties detection, in case electric apparatus mounted on vehicle because
Break down for insulation ag(e)ing；But at present for the Insulation monitoring of electric apparatus mounted on vehicle still mainly passes through manual observation or logical
Crossing the instruments such as megameter is carried out in the way of periodic inspection, and the manpower and materials that this mode expends are big, and easily occur missing inspection,
False retrieval, and equipment deterioration state does not have judging basis, does not have the method for long term monitoring yet, so goes down for a long time, it is easy to occurs
The electrical equipment of operation troubles, circuit or locomotive is aging to cause insulation fault；Such as power locomotive top high pressure equipment is family
Outer installation equipment, it is desirable to which 25kv high voltage electric equipments have enough High-Voltage Insulation performances with locomotive roof, to prevent due to rain
The boisterous infringement such as snow and the attack of thunder and lightning atmospheric over-voltage.If locomotive roof high pressure equipment breaks down or because of other
Reason causes high pressure equipment failure, due to cannot failure judgement situation, once rise pantograph again, will cause electrion,
Ground connection, gently then causes pantograph pan bonding with contact net, heavy then blow contact net.In the end of the year 2006, Luoyang locomotive depot locomotive is just
Because snowing, top insulation is reduced, roof electric discharge, causes a large amount of locomotives to sit, and almost makes western Gansu Province sea line railway transportation paralysis, sternly
Railway transportation is disturbed again.Therefore it is badly in need of a kind of effective detection method of electric locomotive on-board electrical equipment on-line insulating properties of exploitation
And device.
Do not find there be the patent literature constructed with this utility model by patent retrieval, have with this utility model
The patent of certain relation mainly has following：
