Abstract

The invention is suitable for the technical field of substation design in urban rail transit and provides a ground brake resistor of urban rail transit. Control equipment and chopping equipment of the ground brake resistor are arranged in an underground substation. A resistor part of the ground brake resistor includes one or more wall hanging resistance boxes arranged on a wall at ventilation positions of an urban rail transit system. The wall hanging resistance boxes comprise groups of resistance grid units and box protecting shells. The box protecting shells are each in the shape of a cuboid and heat dissipation windows are arranged in six faces of each box protecting shell. The group number of resistance grid units is determined according to the actual mounting environment, and the sizes of the box protecting shells can be adjusted according to the group number of the resistance grid units. The resistor equipment of the ground brake resistor is arranged in form of one or more wall hanging resistance boxes, so that the problems of heat dissipation, land occupancy and coordination and the like due to large heat dissipation amount and large size of the ground brake resistor are solved.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit substation design, in particular to a ground braking resistor for urban rail transit. Background technique [0002] At present, the ground regenerative energy absorption device schemes adopted at home and abroad with relatively mature technology mainly include resistance energy consumption type, capacitor energy storage type, flywheel energy storage type, inverter feedback type, inverter + resistance hybrid type and two-way controllable type, etc. . [0003] Capacitive energy storage type, flywheel energy storage type, two-way controllable type and other equipment are not domestically produced at present, or there are export restrictions, or the price is too high, and the feasibility of domestic promotion and application is small. [0004] Resistive braking is simple, reliable, low in cost, and easy to be accepted by users. Regardless of whether resistance braking is set alone or mixed...
