Embodiment Construction

[0042] refer to Figure 2 to Figure 3 , the present invention is implemented like this:

[0043] A catenary arc suppression control device, used to eliminate catenary arc tripping and burns and other fault phenomena, the arc suppression control device 10 is composed of an arc suppression main controller MCU11, an overvoltage absorber MDA12 and a permanent magnet arc extinguishing switch 13, wherein the overvoltage absorber MDA12 and the permanent magnet arc extinguishing switch 13 are connected in parallel, and the main arc extinguishing controller MCU is the command controller of the permanent magnet arc extinguishing switch 13.

[0044] Every time the electric locomotive 40 passes through the electric phase splitter, it needs to pass through the non-insulated anchor joint and the insulating anchor joint. The non-insulated anchor joint completes the mechanical segmentation function, and the insulating anchor joint completes the two functions of mechanical segmentation and ele...

Abstract

The invention relates to a power supply device, in particular to an arc extinguishing control device for a contact net, which is mainly used for a railway contact net, and is used for eliminating the fault phenomenon of the contact net such as arc discharge, trip, burn and the like. The arc extinguishing control device consists of an arc extinguishing main controller MCU, an overvoltage absorber MDA and a permanent-magnetic controlled arc extinguishing switch, wherein the overvoltage absorber MDA and the permanent-magnetic controlled arc extinguishing switch are connected in parallel, and thearc extinguishing main controller MCU is connected with the permanent-magnetic controlled arc extinguishing switch. The arc extinguishing control device has the advantages that the device with the arc extinguishing capacity assists the arc discharge phenomenon between an electric arc and the contact net; electric appliances with the arc extinguishing capacity are arranged to inhibit the electric arc during the running so as to shorten the arcing time and arcing strength; and the device radically avoids trip accidents of the power supply and burn accidents for the electric appliances.

Description

technical field [0001] The invention relates to a power supply equipment device, in particular to a catenary arc suppression control device mainly used for railway catenary. Background technique [0002] Catenary is a special power supply equipment. Due to the particularity of its structure and use conditions, its failures are also various. Among all kinds of faults of railway electrified catenary equipment, electrical arc burn faults are more harmful because they are difficult to find beforehand, and have attracted more and more attention from power supply operation departments. In the electrified railway, the catenary equipment works under the dual action of force and electricity, so mechanical faults and electric arc burn faults constitute the main body of catenary faults. With the catenary running for many years, the speed of the electrified railway and the increasing traction capacity, the problems of tripping, main transformer failure and catenary burn caused by the e...
