High-voltage enclosed switch cabinet

Abstract

The present invention discloses a high-voltage enclosed switch cabinet. The high-voltage enclosed switch cabinet comprises a cabinet body, a breaker observation window is arranged at the door of the cabinet body, and upper and lower contact boxes are arranged in the cabinet body; a breaker with an isolation switch is arranged between the upper contact box and the lower contact box, the structures of the upper contact box and the lower contact box are same, and the upper contact box and the lower contact box are internally provided with fixed contacts; and the breaker is controlled to switch on or off by the operation mechanism of the breaker, upper and lower isolation switch moving contacts capable of vertically moving are arranged on the breaker, and the breaker controls the on state with the fixed contact through vertical telescoping to realize the mutual locking with the isolation switch. The switch cabinet is configured to directly install a valve on a contact box, the valve is directly pushed to open by a moving contact, and the transmission mode is simple and feasible, any extra transmission mechanisms are not needed, and the operation is convenient; and a breaker with an isolation switch is used to reduce the occupied space to a great extent, greatly decrease the size of a device and facilitate transportation and installation, and an observation window is arranged on the cabinet body, so that the running condition of portions such as a breaker and the like may be timely observed, and the safety of the device is ensured.

Description

technical field [0001] The invention relates to a high-voltage closed switchgear. Background technique [0002] At present, the existing high-voltage (3.6-40.5kV) enclosed switchgears are often heavy in weight, bulky in size, long in conductive circuits, many in connection points, and poor in heat dissipation performance, which is not conducive to safe operation. Contents of the invention [0003] The object of the present invention is to provide a high-voltage closed switchgear with small volume and high safety in view of the deficiencies in the prior art. [0004] The high-voltage closed switch cabinet of the present invention comprises a cabinet body, a circuit breaker observation window is arranged on the cabinet door of the cabinet body, an upper contact box and a lower contact box installed vertically are arranged in the cabinet body, and the upper and lower contact boxes There is a circuit breaker with isolating switch between the boxes. The upper and lower contact...
