Comprehensive monitoring and analyzing device for traction overhead line system

Abstract

The invention discloses a comprehensive monitoring and analyzing device for a traction overhead line system, which comprises a shell, and the shell internally comprises a water draining plate at the top of the shell, the top of the water draining plate is set to be semi-arc-shaped, and the water draining plate is made of an aluminum material; a bolt hole for fixing is formed in the shell, a steel connecting belt is adopted at the bolt hole fixing position, on one hand, the steel connecting belt is used for penetrating through a contact network to be connected with the device through a bolt, and on the other hand, the steel connecting belt and the external ground form a loop through the bolt hole for normal power supply and lightning protection and lightning protection; and the dry-type transformer is arranged in the device, and the transformation ratio of the dry-type transformer is 10.5 kV / 0.4 kV. The traction overhead line system comprehensive monitoring and analyzing device is externally made of novel materials, adopts a totally-closed mode, is internally filled with rare gas sulfur hexafluoride, has good insulation performance, can work well even under the high-temperature condition, is high in adaptability and can adapt to various climatic environment conditions.

Description

Technical field [0001] The present invention relates to the field of monitoring and analysis of rail transit, and is specifically a combined monitoring and analysis device for traction contact mesh. Background technique [0002] Contacting the net arch network is a critical part of the high-speed rail operation. Once the contact network has failed, it will affect the normal operation of the high-speed rail, which will even cause serious casualties, so we need to pay attention to the abnormal wear of the contact network. The reasons for contact network wear are: First, the fixed wear of the bows between the bows between the bows and slides in the bottom of the contact line; the adverse contact of the bow network system is often accompanied by the electrical bow and contact between contact between the network. The phenomenon, that is, the arc assembling arc, which will cause wear, long-term operation, and endless operations. In recent years, the maintenance of the high-speed rail c...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of equipment which is composed of aluminum alloy outer shell and carbon fiber inner shell and filled with sulfur hexafluoride gas inside, which overcomes the deficiencies of the prior art, and has a reasonable structural design, which effectively solves the existing problems. The monitoring device cannot detect the location of the fault in a specific and timely manner and monitor the cause of the wear of the catenary in real time, and cannot predict in advance whether a fault will occur and the probability of occurrence, and cannot remind humans to replace and repair the catenary. At the same time, Since the monitoring systems of the police stations in various jurisdictions can only measure the current and power quality of the high-speed rail when it is running, it cannot measure the conditions such as arcing and pantograph-catenary wear.
