Problems solved by technology

Although the operation switch is reliable, due to manual operation, it is far from meeting the requirements in terms of response time and work efficiency
However, some automatic power-off and transmission schemes are shelved because they are not suitable for complex and changeable conditions, especially underground conditions.
In particular, some wireless control devices are very sensitive to the interference of clutter and clutter in the underground or stripping field, and most of them require manual operation, resulting in many refusals and malfunctions, affecting normal operation
As for other control methods, such as on-rail pressure sensor method, auxiliary switch method on contact line, infrared detection method on roadway wall, etc., they cannot be adopted due to the harsh underground environment and many artificial conditions.

Abstract

The automatic power on-off device for electric locomotive consists of a host machine and auxiliary contact lines, and the contact line feeding power line, the contact line of the controlled electric locomotive and the pantograph constitute the control system. The host machine includes a machine core comprising a logically controlling relay system, a main circuit, a heat dissipating system, etc; and a explosion suppressing and heat dissipating casing. The host machine is connected to the outer auxiliary contact lines and inner auxiliary contact lines through the power-off signal line and power-on signal line and connected to the power line and controlled electric locomotive contact line through the feeding cable and the load controlling cable.

Description

Technical field [0001] The invention relates to a switchgear for carrying out power supply operation for the frictional contact line of an electric locomotive and performing power transmission stop operation. Background technique [0002] Coal mine underground transportation lanes (including the underground parking lot), the electric locomotive catenary needs to be powered in sections, especially the people-vehicle yard and the section where people pass frequently. This is of great significance to personal safety, production safety and energy saving. Relevant departments have stipulated that after people and vehicles enter the parking lot to stop, the contact line of the whole column of people and vehicles (not including locomotives) must be powered off. [0003] Segmental power outage refers to dividing the entire transportation line into several sections. On the one hand, when the locomotive travels to a certain section, the section is in the state of power supply, while ...
