Abstract

Disclosed is a railway vehicle bipolar isolating switch electric control device, belonging to control devices for DC 1500V isolating switches for contact screens of railway vehicles. The railway vehicle bipolar isolating switch electric control device comprises a bipolar isolating switch and an electric control device. The electric control device is structurally characterized in that: a motor drives a brake driving shaft and a roller shaft through a gear wheel; the primary transmission ratio is 4:1 and the secondary transmission ratio is 1:1; two concave rollers are installed on the roller shaft, with the notches staggered at an angle of 180 degrees so as to enable the two switches below to be connected or disconnected. In this way, the brake circuits can be interlocked. The bipolar switch is good in periodicity, little in wear and long in service life; the bake circuits of the motor can be interlocked; the connection and disconnection of the contacts of the auxiliary switch can be automatically controlled, thus meeting the requirements of controlling and protecting the motor and outputting signals.

Description

technical field [0001] The invention relates to a DC isolating switch, in particular to a DC1500V bipolar isolating switch used in urban rail transit catenary and its electric control device technology. Background technique [0002] In my country, 10 cities including Beijing, Shanghai, and Guangzhou have successively built urban rail transit systems, and a total of 22 lines have been put into operation or trial operation, with a total mileage of 602 kilometers. In addition, in the next 10 years, 15 cities in my country will build rail transit lines with a total length of 1,700 kilometers and a total investment of 620 billion yuan. However, the research and development and manufacture of DC1500V bipolar isolating switches required by the rail transit catenary are still blank in China. As a result, the domestic rail transit catenary has to be replaced by two completely independent unipolar isolating switches. Such substitutes obviously have the following deficiencies and defe...
