Abstract
The utility model discloses a single-pole switch cabinet for railroad electrification, which comprises a cabinet body and a mounting vehicle which can draw the cabinet body out. The top in the cabinet body is fixed with a secondary instrument box. The sidewall in the cabinet body is fixed with an insulator. The insulator is respectively fixed with an upper static contact and a lower static contact. On a holder of the mounting vehicle a breaker assembly mounting board, a pull rod linkage component, a current transformer and vehicle wheels are fixed. A vacuum breaker is fixed between an upper clamping element and a lower clamping element. The upper clamping element is fixed with an upper dynamic contact. The upper end which connects with a copper bar II is fixed with a lower dynamic contact. The upper dynamic contact is connected with the upper static contact. The lower dynamic contact is connected with the lower static contact. The switch cabinet supports everywhere and is reliably mounted. The stress is seriously considered when in electric connection to ensure the connection in a safe way. The fixed part and the mounting vehicle in the cabinet body are separately connected, which is easy to maintain and helpful to operate.
