Embodiment Construction

[0020] The structure of the 1500V DC grid disconnecting switchgear of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0021] The 1500V DC grid isolation switchgear cabinet body 12 of the invention is as image 3 As shown, the overall dimensions are 1500mm (width) x 800mm (depth) x 2300mm (height). Its internal structure is as figure 1 , 2 As shown, it is divided into upper and lower compartments separated by a partition, the upper compartment is the secondary control room, namely the secondary compartment 4, and the lower compartment is the primary high pressure chamber, namely the primary compartment 5. The upper and lower compartments are respectively equipped with left and right doors, and the right door of the upper compartment is equipped with an indicator light for displaying the opening and closing state of the isolating switch, a changeover switch for changing the electric operation mode (proximity or telemetry...

Abstract

The invention provides a 1500V direct current Internet isolation switchgear. The isolation switchgear comprises a cabinet body. An Internet isolation switch I, an Internet isolation switch II and a contact isolation switch are all arranged on a transverse installation board of a first compartment in the cabinet body. A connection copper bar I is connected with an outlet board I of the Internet isolation switch I and an inlet board of the contact isolation switch. A connection copper bar II is connected with an outlet board II of the Internet isolation switch II and an outlet board of the contact isolation switch. The Internet isolation switch I and the inlet board and the outlet board of the Internet isolation switch II are respectively connected with an incoming cable and an outgoing cable. A secondary control loop is arranged on door plates of the first and second compartments. In the invention, the isolation switchgear a complete sets so that a process of installation and debugging on site can be omitted. Because the isolation switch is installed in the cabinet body, a protection grade is improved from IPOX to IP3X. The isolation switchgear has an exquisite shape. Maintenance is convenient. A 75% installation space can be saved. After realizing localization, construction costs of urban rail transit can be reduced.

Description

technical field [0001] The invention relates to a 1500V direct current grid disconnecting switchgear suitable for urban rail, subway and other rail traffic. Background technique [0002] 1500V DC isolating switch is a necessary product for the normal operation of urban rail and subway. It undertakes the tasks of normal power supply for vehicle operation and power failure isolation and conversion circuit in case of failure. It is an important equipment to ensure the normal operation of urban rail and subway. [0003] At present, the DC isolating switch is mostly installed on the pillar or the side wall of the building. This installation method is not convenient for installation, commissioning, operation and maintenance. The method of purchasing foreign or joint venture products has been adopted, which has high economic costs and difficult maintenance. Contents of the invention [0004] In order to solve the problems in the above-mentioned technologies, the purpose of the p...
