Problems solved by technology

In fact, this method only replaces manual operation, and there are problems such as a long power outage area, a large loss of locomotive speed and traction, especially when the locomotive is running on a long slope, the loss is more obvious, so this method is not true. Achieved the purpose of automatic phase separation

Embodiment Construction

[0027] The technical problems to be solved, the technical effects and the technical features of the technical solutions of the present invention will be further described below in conjunction with the specific embodiments of the present invention shown in the accompanying drawings.

[0028] The basic principle of the electric locomotive pantograph arc extinguishing device of the present invention is: the AC power of the single-phase power grid is introduced into the arc extinguishing device composed of silicon stack components through the two insulated slide plates 2 and 3 of the pantograph through connecting wires In the process, the zero-crossing time of alternating current is extended every half cycle, and the half-wave arc extinguishing principle is used to restore the energy and medium in the arc gap to achieve the purpose of arc extinguishing.

[0029] Please refer to Fig. 1 and Fig. 2 first, which are schematic diagrams of the front view and top view of the electric loco...

Abstract

The invention relates to an electric locomotive pantograph arc blowout device, which comprises sliding plates arranged on a pantograph, an electrical connector and an automatic arc blowout component, wherein the bow head of the pantograph is provided with two sliding plates which are insulated with each other; and the automatic arc blowout component is arranged between the sliding plates of the pantograph and a main circuit breaker in series. The electric locomotive pantograph arc blowout device has the advantages of flexibility, convenience, and less loss of the locomotive speed and the tractive force because a driver reduces the complicated operations when passing through a split-phase point, technically eliminates the influences caused by surge current and switching over-voltage, is safer and more reliable, and has long service life and less investment.

Description

technical field [0001] The invention relates to a device capable of automatically running AC-powered electric locomotives, electric train units, urban rail cars, and subway locomotives between catenary phases, in particular to a pantograph arc-extinguishing device for electric locomotives. Background technique [0002] The catenary and the pantograph of the locomotive in the power transportation system are important equipment for transmitting electric energy to the locomotive to ensure the normal operation of the locomotive when the locomotive is running. It has always been the goal pursued by people to realize automatic phase separation of electric locomotives in AC power supply. [0003] The known technology is that when the locomotive passes the phase point, the ground automatically switches the electric phase-splitting device. This device has a complex structure, a very cumbersome control method, and poor anti-interference performance. [0004] Another way is the pole-m...
